- the reinforcement may be for the purpose of increasing the strength against the external impact to be applied to the frame (10 of FIG. 2) and for the purpose of adding, maintaining, and enhancing insulation from the outside.
- the bus bar 20 of FIG. 3 when the manufactured bus bar 20 of FIG. 3 is connected to the battery of the vehicle, the bus bar may be affected by vibration generated while the vehicle is driving. At this time, the vibration and pressure transmitted from the surrounding structure may be affected by the bending, such as a kind of reinforcement process to increase the resistance to the bending.
- the reinforcement part (reinforcement part) position may be one or more positions of the body part (420.520.620 of FIG. 5) and the sensing part (410, 510, 610 of FIG. 5), and the frame (10 of FIG. 2).

- FIG. 1 is a flowchart illustrating a process of manufacturing a bus bar (20 of FIG. 2) according to an embodiment of the present invention.
- the busbar 20 of FIG. 2 may be manufactured in the order of manufacture of a frame (S1), a primary reinforcement injection (S2), a secondary reinforcement injection (S3), and stripping (S4).
- the frame manufacture S1 may manufacture a frame (10 of FIG. 2) including a sensing unit (110 of FIG. 2) and a body unit (120 of FIG. 2).
- Frame (10 of FIG. 2) manufactured through a method such as a press may be manufactured as a bus bar (20 of FIG. 3) while being coupled through reinforcement and injection.
- the sensing unit 110 and the body unit 120 may be integrally formed, and do not include a separate bonding process. Therefore, generation
- the mechanical performance can be increased by being manufactured integrally.
- the mechanical performance may refer to the ability to maintain the bonding force by the bonding force, vibration, and the like, and the ability to resist breakage that may occur from external forces.
- Such performance is, for example, when a bus bar (20 in FIG. 3), which is an embodiment of the present invention, is included in a vehicle part, etc., has higher resistance than a bus bar manufactured by a combination of two members against vibration of the vehicle. Therefore, it may be advantageous.
- it is also possible to expect to improve insulation.

이하, 도면을 참조하여 본 발명의 구체적인 실시형태를 설명하기로 한다. 그러나 이는 예시에 불과하며 본 발명은 이에 제한되지 않는다.Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is only an example and the present invention is not limited thereto.
본 발명을 설명함에 있어서, 본 발명과 관련된 공지기술에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명을 생략하기로 한다. 그리고, 후술되는 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들로서 이는 사용자, 운용자의 의도 또는 관례 등에 따라 달라질 수 있다. 그러므로 그 정의는 본 명세서 전반에 걸친 내용을 토대로 내려져야 할 것이다.In describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or an operator. Therefore, the definition should be made based on the contents throughout the specification.
본 발명의 기술적 사상은 청구범위에 의해 결정되며, 이하의 실시예는 본 발명의 기술적 사상을 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 효율적으로 설명하기 위한 일 수단일 뿐이다.The technical spirit of the present invention is determined by the claims, and the following embodiments are merely means for efficiently explaining the technical spirit of the present invention to those skilled in the art.
그리고, 이하에서는 프레임(도2 의 10)을 강화하기 위한 방법 및 상기 방법으로 제조된 버스바(도 3의 20)에 대해서 후술하기로 한다. 여기서 강화란, 프레임(도 2의 10)에 가해질 외부충격에 대하여 강도를 증진시키는 목적과 외부로부터 절연성을 부가, 유지, 증진하기 위한 목적일 수 있다. 예를 들면, 제조된 버스바(도 3의 20)가 차량의 배터리와 연결되는 경우에는 차량이 주행 중에 발생하는 진동에 대한 영향을 받을 수 있다. 이때 주변 구조물로부터 전달되는 진동 및 가압에 의해 밴딩 등의 영향을 받을 수 있는데, 여기서 밴딩에 대하여 저항력을 증진시키는 일종의 강화과정이라고 할 수 있다. 따라서, 기계피로(fatigue)의 원인이 되는 상기 밴딩으로부터 강도를 증진시키기 위해 밴딩으로 인해 가장 취약한 지점을 제조과정에서 강화부(보강부)로 형성할 수 있다. 이러한 강화부(보강부) 위치는 바디부(도 5의 420. 520. 620) 및 센싱부(도 5의 410, 510, 610) 중 하나 이상의 위치가 될 수 있고, 프레임(도 2의 10)이 연결부(도 2의 112)를 포함할 경우, 연결부(도 2의 112)에 형성될 수 있다. 예를 들어, 상대적으로 폭이 좁게 형성되어 밴딩으로부터 취약한 연결부에 강화부가 형성될 수도있다. 물론, 연결부(도 2의 112)에는 만곡부(도 2의 113)가 형성되어 상기 밴딩이 가해지는 지점에 대하여 탄성을 지니도록 구조적으로 형성될 수도 있다.In the following description, a method for reinforcing the frame (10 of FIG. 2) and a bus bar (20 of FIG. 3) manufactured by the method will be described later. In this case, the reinforcement may be for the purpose of increasing the strength against the external impact to be applied to the frame (10 of FIG. 2) and for the purpose of adding, maintaining, and enhancing insulation from the outside. For example, when the manufactured bus bar 20 of FIG. 3 is connected to the battery of the vehicle, the bus bar may be affected by vibration generated while the vehicle is driving. At this time, the vibration and pressure transmitted from the surrounding structure may be affected by the bending, such as a kind of reinforcement process to increase the resistance to the bending. Therefore, the most vulnerable point due to the bending can be formed as a reinforcement part (reinforcement part) in the manufacturing process in order to increase the strength from the banding which causes mechanical fatigue. The reinforcement part (reinforcement part) position may be one or more positions of the body part (420.520.620 of FIG. 5) and the sensing part (410, 510, 610 of FIG. 5), and the frame (10 of FIG. 2). In the case of including the connection part 112 of FIG. 2, the connection part 112 may be formed in the connection part 112 of FIG. 2. For example, the reinforcement may be formed in a connection that is relatively narrow and weak in bending. Of course, the bent portion (113 of FIG. 2) is formed in the connection portion (112 of FIG. 2) may be structurally formed to have elasticity with respect to the point where the bending is applied.
또한, 외부로부터 절연성을 부가, 유지, 증진하기 위한 목적으로서, 피복의 기능을 할 수 있다. 즉, 외부로부터 노출되는 면적을 은폐시킴으로서 주변 구조물과의 불가피한 접촉에 의해 발생할 수 있는 쇼트 등의 전기적 사고를 방지할 수 있다. 상기 주변구조물뿐만 아니라 수분에 의한 접촉으로 인한 전기적 사고를 미연에 방지할 수 있다. 따라서, 경화 후에 전도체로 기능할 수 있는 강화주입물을 사출 시에 주입하지 않고 전기전도성을 억제할 수 있는 소재를 사출시에 주입할 수 있다. 예를 들어 수지재를 포함한 강화주입물이 사출시에 주입되어 절연성을 부가, 유지, 증진 시킬 수 있다.Moreover, it can function as a coating | cover for the purpose of adding, maintaining, and improving insulation from the exterior. That is, by concealing the area exposed from the outside, it is possible to prevent electrical accidents such as shorts that may occur due to inevitable contact with the surrounding structure. Electrical accidents due to contact with moisture as well as the peripheral structure can be prevented in advance. Therefore, a material capable of suppressing electrical conductivity can be injected at the time of injection, without injecting a reinforcement injection product that can function as a conductor after curing. For example, reinforcement injections containing resin materials can be injected during injection to add, maintain and enhance insulation.
이하에서는, 상기 강화부를 형성하기 위해 복수 회 강화 사출 과정이 이루어지는 실시예와 한 차례를 통해 강화사출 과정이 이루어지는 실시예에 대하여 후술하도록 한다. 1차 및 2차 사출성형이 이루어지는 실시예를 도 1 내지 도 6을 통해 설명하도록 하고, 도 7을 통해 한 차례 성형사출 과정을 통해 강화부가 형성되는 과정을 설명하도록 한다. 그리고, 도 7을 참조하여 설명할 때는 도 1 내지 도 6을 참조하여 설명한 내용과 비교하여, 차이점을 위주로 설명하도록 한다.Hereinafter, an embodiment in which a plurality of reinforcement injection processes are performed a plurality of times and a reinforcement injection process through one turn to form the reinforcement part will be described below. An embodiment in which primary and secondary injection molding are performed will be described with reference to FIGS. 1 to 6, and a process of forming a reinforcement part through a molding injection process will be described with reference to FIG. 7. In addition, when the description is made with reference to FIG. 7, the difference will be mainly described in comparison with the contents described with reference to FIGS. 1 to 6.
도 1은 본 발명의 일 실시예에 따른 버스바(도 2의 20)가 제조되는 과정을 나타낸 순서도이다.1 is a flowchart illustrating a process of manufacturing a bus bar (20 of FIG. 2) according to an embodiment of the present invention.
도 1을 참조하면, 버스바(도 2의 20)는 프레임 제조(S1), 1차강화주입물 주입(S2), 2차강화주입물 주입(S3) 및 탈거(S4)의 순서로 제조될 수 있다. 구체적으로, 프레임 제조(S1)는 센싱부(도 2의 110) 및 바디부(도 2의 120)를 포함하는 프레임(도 2의 10)을 제조할 수 있다. 프레스 등의 방법을 통해 제조된 프레임(도 2의 10)은 강화물과 사출을 통해 결합되면서 버스바(도 3의 20)로 제조가 될 수 있다. 상기 프레임(도 2의 10)은 센싱부(도 2의 110)에 만곡부(1113) 및 센싱공(111a) 등의 형상 및 바디부(120)의 만곡부(123) 및 중공홀(121a) 등의 형상을 포함하여 제조될 수 있다. 즉, 버스바(도 3의 20)의 베이스가 되는 형상이 마련될 수 있다. 여기서 센싱부(110) 및 바디부(120)는 일체형으로 형성될 수 있으며, 별도의 접합과정을 포함하지 않는다. 따라서, 결합구조에 의한 내구력 저하의 발생을 방지할 수 있다.Referring to FIG. 1, the busbar 20 of FIG. 2 may be manufactured in the order of manufacture of a frame (S1), a primary reinforcement injection (S2), a secondary reinforcement injection (S3), and stripping (S4). Can be. In detail, the frame manufacture S1 may manufacture a frame (10 of FIG. 2) including a sensing unit (110 of FIG. 2) and a body unit (120 of FIG. 2). Frame (10 of FIG. 2) manufactured through a method such as a press may be manufactured as a bus bar (20 of FIG. 3) while being coupled through reinforcement and injection. The frame (10 of FIG. 2) has a shape such as a curved portion 1113 and a sensing hole 111a and a curved portion 123 and a hollow hole 121a of the sensing portion (110 of FIG. 2). It can be produced including the shape. That is, a shape that serves as a base of the bus bar 20 of FIG. 3 may be provided. Here, the sensing unit 110 and the body unit 120 may be integrally formed, and do not include a separate bonding process. Therefore, generation | occurrence | production of durability fall by the coupling structure can be prevented.
즉, 일체형으로 제조됨으로써 기계적 성능이 증가될 수 있다. 여기서 기계적 성능은, 결합력 및 진동 등에 의해 결합력을 유지하는 성능 및 외력으로부터 발생할 수 있는 파손에 저항할 수 있는 성능 등을 의미할 수 있다. 이러한 성능은 예를 들어, 차량의 부품 등에 본 발명의 일 실시예인 버스바(도 3의 20)가 포함될 경우에 차량의 진동 등에 대하여 두 부재의 결합에 의해 제조된 버스바에 비해 보다 높은 저항성을 가지므로 유리할 수 있다. 물론, 상술한 바와 같이 절연성의 증진을 기대할 수도 있다. 이러한 강화부로부터 기대할 수 있는 효과는 선택적이므로, 당업자에 의해 절연성보다 강성을 우선시 하면 강화주입물이 금속재로 결정될 수 있고, 강성보다 절연성을 우선시 하면 수지재와 같은 소재로 결정될 수 있다. 따라서, 강화주입물의 소재는 선택적이며, 복수의 소재를 융합하여 절연성과 강성의 비중을 조절할 수 있다. 나아가, 강화부에 탄성을 부여할 수도 있다.That is, the mechanical performance can be increased by being manufactured integrally. Here, the mechanical performance may refer to the ability to maintain the bonding force by the bonding force, vibration, and the like, and the ability to resist breakage that may occur from external forces. Such performance is, for example, when a bus bar (20 in FIG. 3), which is an embodiment of the present invention, is included in a vehicle part, etc., has higher resistance than a bus bar manufactured by a combination of two members against vibration of the vehicle. Therefore, it may be advantageous. Of course, as described above, it is also possible to expect to improve insulation. Since the effect that can be expected from such a reinforcing part is optional, the reinforcement injection may be determined as a metal material when the rigidity is prioritized by the person skilled in the art, and when the insulation is prioritized by the rigidity, it may be determined by a material such as a resin material. Therefore, the material of the reinforcing injection is optional, it is possible to adjust the specific gravity of the insulation and rigidity by fusing a plurality of materials. Furthermore, elasticity can also be provided to a reinforcement part.
그리고, 상기 프레임 제조(S1) 과정에서 제조된 프레임은 예를 들어 5 mm 일 수 있다. 상기 5 mm 는 사출을 통해 강화되는 과정을 거치지 않고 제조되는 버스바의 두께의 50% 에 해당하는 두께의 일 예로서, 0.5 mm 에 한정되는 것은 아니다. 이하에서는 5 mm 두께로 제조되는 프레임을 예시로 하여, 버스바를 제조하는 과정을 설명하기로 한다.In addition, the frame manufactured in the frame manufacturing process S1 may be, for example, 5 mm. The 5 mm is an example of the thickness corresponding to 50% of the thickness of the bus bar manufactured without undergoing the process of strengthening through injection, it is not limited to 0.5 mm. Hereinafter, a process of manufacturing a bus bar will be described by taking a frame manufactured to a thickness of 5 mm as an example.
상기 프레임 제조(S1)를 통해 제조된 프레임(도 2의 10)은 내구력이 약한 부분, 즉 외력에 의해 응력집중이 발생할 수 있는 부분이 강화될 수 있다. 예를 들어, 프레임(도 2의 10)을 강화하기 위한 목적으로 강화주입물이 주입될 수 있다. 따라서, 상기 강화주입물을 주입하여 사출하기 위해 프레임(도 2의 10)을 1차사출성형금형에 배치시키고 1차강화주입물의 주입(S2)이 행해질 수 있다. 1차강화주입물은 예를 들어, 프레임(도 2의 10)의 일면을 대상으로 주입될 수 있다. 여기서, 프레임(도 2의 10)의 일면은 프레임(도 2의 10)의 저면이 될 수 있고, 저면의 일부 또는 전면이 될 수 있다.The frame (10 of FIG. 2) manufactured through the frame manufacturing (S1) may be strengthened a portion having a weak durability, that is, a portion where stress concentration may occur due to external force. For example, a reinforcement injection may be injected for the purpose of reinforcing the frame (10 in FIG. 2). Therefore, in order to inject and inject the reinforcement injection, a frame (10 of FIG. 2) may be disposed in the primary injection molding mold and injection (S2) of the primary reinforcement injection may be performed. The primary reinforcement injection may be injected, for example, on one surface of the frame (10 of FIG. 2). Here, one surface of the frame (10 of FIG. 2) may be the bottom of the frame (10 of FIG. 2), and may be part or the front of the bottom.
그리고 이후에 2차강화주입물의 주입(S3)이 행해지기 위하여, 금형을 재배치 시킬 수 있다. 1차강화주입물 주입(S2)에서 저면을 대상으로 강화주입물이 주입되었다면, 상부금형만 재배치되어 2차강화주입물이 주입될 수 있다. 이러한 경우에는, 프레임(도 2의 10)의 타면을 대상으로 2차강화주입물이 주입(S3)될 수 있다. 여기서 타면은 프레임(도 2의 10)의 상면이 될 수 있고, 상기 상면의 일부 또는 전체가 될 수 있다.Then, the mold can be rearranged in order to perform the injection of the secondary strengthening injection (S3). If the reinforcement injection is injected to the bottom in the primary reinforcement injection (S2), only the upper mold may be rearranged and the secondary reinforcement injection may be injected. In this case, the secondary strengthening injection may be injected (S3) on the other surface of the frame (10 of FIG. 2). The other surface may be an upper surface of the frame (10 of FIG. 2), and may be part or all of the upper surface.
다만, 1차강화주입물 주입(S2) 및 2차강화주입물(S3) 과정에서 센싱부(도 2의 110)는 전기전도가 가능한 단자로써, 강화주입물의 주입으로부터 차단될 수 있다. 따라서, 센싱부(도 2의 110)는 버스바(도 3의 20)로 제조 후에도 노출될 수 있다. 여기서 프레임(도 2의 10)은 비철금속으로 제조될 수 있으며, 예를 들면, 알루미늄 또는 동이 될 수 있다. 그리고 1차 및 2차 시에 주입되는 강화주입물은 적어도 수지를 포함할 수 있다. 그러므로 센싱부(도 2의 110)에 강화주입물이 차단되지 않을 경우, 센싱부(도 2의 110)를 통한 전기전도가 불가능할 수 있으므로 강화주입물이 차단될 수 있다. 나아가, 센싱부(도 2의 110)는 금, 은, 니켈, 주석 및 아연 중 하나의 소재로 도금될 수 있다. However, in the first reinforced injection (S2) and the second reinforced injection (S3) process, the sensing unit (110 of FIG. 2) as a terminal capable of electrical conductivity, it can be blocked from the injection of the reinforced injection. Accordingly, the sensing unit 110 of FIG. 2 may be exposed even after manufacture with the bus bar 20 of FIG. 3. The frame 10 of FIG. 2 may be made of nonferrous metal, for example, aluminum or copper. In addition, the reinforcement injection injected at the first and the second time may include at least a resin. Therefore, when the reinforcement injection is not blocked in the sensing unit (110 of FIG. 2), the electrical conductivity through the sensing unit (110 of FIG. 2) may be impossible, and thus the reinforcement injection may be blocked. Furthermore, the sensing unit 110 of FIG. 2 may be plated with one of gold, silver, nickel, tin, and zinc.
한편, 1차강화물주입 및 2차강화주입물을 주입하기 위해 배치된 금형은 프레임(도 2의 10)이 상기 금형 내에 고정된 후에 상기 강화주입물이 주입(S2, S3)될 수 있는데, 주입되는 강화주입물에 의해 상기 금형 내에서 프레임(도 2의 10)이 이동되는 것을 방지하기 위해 고정수단이 형성될 수 있다.On the other hand, the mold disposed for injecting the primary reinforcement injection and the secondary reinforcement injection can be injected (S2, S3), the reinforcement injection after the frame (10 in Figure 2) is fixed in the mold, injection Fixing means may be formed to prevent the frame (10 of FIG. 2) from being moved in the mold by the reinforcing injection.
상기 프레임에는 홀, 스파이크 및 드로윙 중 하나 이상이 형성될 수 있으며, 1차강화주입물 및 2차강화주입물과 프레임(도 2의 10)이 서로 접촉되는 접촉면에 형성될 수 있고, 접촉면 중 하나 이상의 접촉면에 형성되어 프레임(도 2의 10)과 1차강화주입물 및 2차강화주입물 중 하나 이상 간의 밀착력을 증가시킬 수 있다.The frame may be formed with one or more of holes, spikes and drawing, the primary reinforcement injection and the secondary reinforcement injection and the frame (10 in FIG. 2) may be formed in contact with each other, one of the contact surface It may be formed on the above contact surface to increase the adhesion between the frame (10 in FIG. 2) and one or more of the primary reinforcement injection and the secondary reinforcement injection.
한편, 주입된 강화주입물은 프레임(도 2의 10)에 고착되어 프레임(도 2의 10)에 내구성이 낮은 부분을 강화시킬 수 있다. 또한 이러한 강화주입물은 내구력의 증가 목적으로 행해질 수 있지만, 방열면을 형성하기 위해 행해질 수도 있다. 예를 들어, 바디부(120)의 일면에 강화주입물이 주입될 때 일부면적에 한하여 주입되도록 금형에 배치했을 때 강화주입물이 공급되지 않은 면적은 외부로 노출이 될 수 있다. 이러한 노출된 면은 버스바(도 3의 20)의 제조 후에도 노출이 되므로 전류가 흐르는 과정에서 발생하는 열이 방열되는 면이 될 수 있다. 예를 들어, 방열할 수 있는 면은 바디부(120)의 일면으로서 노출면적이 넓을수록 방열에 유리할 수 있다.Meanwhile, the injected reinforcement injection may be fixed to the frame (10 of FIG. 2) to reinforce the low durability portion of the frame (10 of FIG. 2). This reinforcement injection can also be done for the purpose of increasing durability, but can also be done to form a heat dissipation surface. For example, when the reinforcement injection is placed in the mold so that only a partial area is injected when one of the reinforcement injection is injected into one surface of the body part 120, the area where the reinforcement injection is not supplied may be exposed to the outside. Since the exposed surface is exposed even after the manufacture of the bus bar (20 in FIG. 3), the heat generated during the flow of the current may be a heat dissipating surface. For example, the heat dissipating surface is one surface of the body portion 120, and the wider the exposed area, the better the heat dissipation.
이어서, 금형의 탈거(S4)에서는, 강화주입물 주입(S2, S3)에서 프레임(도 2의 10)에 가이드(도 4의 330)를 더 포함하여 제조한 경우에, 가이드(도 4의 330)와의 분리가 될 수 있다. 이와 관련하여 도 4를 참조하여 구체적으로 후술하기로 한다. Subsequently, in the removal (S4) of the mold, when the guide (330 in FIG. 4) is further included in the frame (10 in FIG. 2) and manufactured in the reinforcement injection (S2, S3), the guide (330 in FIG. ) Can be separated from. In this regard will be described later in detail with reference to FIG.
도 2는 본 발명의 일 실시예에 따른 프레임(10)의 사시도이다.2 is a perspective view of a frame 10 according to an embodiment of the present invention.
도 2를 참조하면, 프레임(10)은 센싱부(110) 및 바디부(120)를 포함할 수 있다. 여기서 센싱부(110)는 단자와의 연결을 위해 센싱공(111a)이 형성될 수 있고, 상기 단자와의 이격거리에 따라 연결부(112)를 통해 바디부(120)와 연결될 수 있다. 즉, 센싱부(110)는 연결부(112)의 일측과 연결되고, 연결부(112)의 타측이 바디부(120)와 연결됨으로써, 센싱부(110) 및 바디부(120)는 전기적으로 연결이 될 수 있다. 본 실시예는 연결부(112) 상에 만곡부(113)가 형성되어 구조적으로 프레임(10)에 탄성을 부여할 수 있다. 앞서 설명한 바와 같이 차량의 부품에 포함될 경우 주행 중인 차량에 의해 진동이 발생할 수 있고 이에 대해 저항력 증가가 될 수 있는 구조일 수 있다. 상기 만곡부(113)는 바디부(120)에도 형성될 수 있다. 바디부(120)의 만곡부(123) 역시 상기와 같은 이유일 수 있다.Referring to FIG. 2, the frame 10 may include a sensing unit 110 and a body unit 120. The sensing unit 110 may be formed with a sensing hole (111a) for connecting to the terminal, it may be connected to the body portion 120 through the connecting portion 112 according to the separation distance with the terminal. That is, the sensing unit 110 is connected to one side of the connecting portion 112, the other side of the connecting portion 112 is connected to the body portion 120, the sensing unit 110 and the body portion 120 is electrically connected Can be. In this embodiment, the curved portion 113 is formed on the connection portion 112 to structurally impart elasticity to the frame 10. As described above, when included in the parts of the vehicle, vibration may be generated by the driving vehicle, and the structure may increase resistance thereto. The curved portion 113 may also be formed in the body portion 120. The curved portion 123 of the body 120 may also be the same reason as described above.
상기 프레임(10)은 앞서 설명한 바와 같이 두께가 0.5 mm 일 수 있다. 이러한 두께는 강화부(도 3의 213a, 220a)가 형성됨으로써, 더 두꺼워 질 수 있으므로, 프레임(10)을 제조할 때, 강화부의 두께를 고려하여 결정될 수 있다. 즉, 강화부(도 3의 213a, 220a)가 형성되지 않거나 일측면에만 형성되는 경우에는 제조 시에, 프레임(10)의 두께가 1 mm 내지 1.5 mm 로 결정될 수 있다.As described above, the frame 10 may have a thickness of 0.5 mm. This thickness may be made thicker by forming the reinforcement parts (213a and 220a of FIG. 3), and thus may be determined in consideration of the thickness of the reinforcement part when manufacturing the frame 10. That is, when the reinforcing parts (213a and 220a of FIG. 3) are not formed or are formed only on one side, the thickness of the frame 10 may be determined to be 1 mm to 1.5 mm at the time of manufacture.
한편, 상기 만곡부(123)에 의해 바디부(120)는 골부(121)와 요부(122)가 형성될 수 있다. 골부(121), 요부(122) 및 만곡부(123) 중 일부에는 중공홀(121a)이 형성될 수 있다. 도시된 예시는 골부(121)에 중공홀(121a)이 형성된 예시이나, 요부에도 형성가능하며, 상기 중공홀(121a)을 통해 방열 및 전기 저저항성 등의 효과를 기대할 수 있다.Meanwhile, the valley portion 121 and the recess portion 122 may be formed in the body portion 120 by the curved portion 123. A hollow hole 121a may be formed in some of the valleys 121, the recesses 122, and the curved portions 123. The illustrated example is an example in which the hollow hole 121a is formed in the valley part 121, but may be formed in the recessed part, and effects such as heat dissipation and electrical low resistance may be expected through the hollow hole 121a.
특히, 방열과 관련해서는 만곡부(123)에 의해 바디부(120)의 공기중 노출면적이 증대되어 방열효과를 더욱 증진시킬 수 있다. 물론 이러한 효과는 연결부(112) 상에 형성된 만곡부(113)에도 해당될 수 있다. 또한, 프레임(10)에 1차강화물(도 3의 222a) 및 2차강화물(도 3의 223a)이 위치된 후에도 외측으로 노출되는 표면이 형성될 경우 상기 노출되는 표면을 통해 방열될 수 있다.In particular, in relation to heat dissipation, the exposed area in the air of the body 120 may be increased by the curved portion 123 to further enhance the heat dissipation effect. Of course, this effect may also correspond to the curved portion 113 formed on the connection portion 112. In addition, even after the primary reinforcement (222a of FIG. 3) and the secondary reinforcement (223a of FIG. 3) are positioned in the frame 10, the surface exposed to the outside may be radiated through the exposed surface.
도 3(a) 및 도 3(b)를 참조하면, 도 2의 프레임(10)에 강화주입물(222a, 223a)이 공급되어 제조된 버스바(20)로서, 버스바(20)는 프레임(10)에 강화부(213a, 220a)를 더 포함할 수 있다. 강화부(213a, 220a)의 형성에 의해 버스바(20)는 전체 또는 국부적으로 두께가 증가될 수 있다. 본 예시는 만곡부(213) 및 바디부(220)의 일부에 강화주입물(222a, 223a)이 주입된 예시이며, 바디부(220) 및 만곡부(213)가 강화주입물(222a, 223a)에 의해 전류통과 단면적이 증가되었으므로, 전기저항이 감소하여 전기전도율의 증가 및 진동에 의한 내구력이 증진될 수 있다.3 (a) and 3 (b), the bus bars 20 are manufactured by supplying reinforcing injections 222a and 223a to the frame 10 of FIG. 2, and the bus bars 20 are frames. The reinforcement parts 213a and 220a may be further included in 10. By forming the reinforcement parts 213a and 220a, the bus bar 20 may be increased in thickness overall or locally. This example is an example in which reinforcing injections 222a and 223a are injected into a portion of the curved portion 213 and the body portion 220, and the body portion 220 and the curved portion 213 are inserted into the reinforcement injections 222a and 223a. Since the current passing cross-sectional area is increased, the electrical resistance is reduced to increase the electrical conductivity and the durability by vibration.
상기와 같이 강화부(213a, 221a) 형성은 1차사출성형 및 2차사출성형에 의해 선택적으로 형성될 수 있으므로, 예를 들면, 만곡부(213)에 강화주입물(222a, 223a)이 공급되어 강화부(213a)가 형성될 수 있고, 별도의 부재와 연결될 수 있는, 바디부(120)의 일단에 강화부(220a)가 형성될 수 있다. 이처럼 강화부(213a, 220a)의 형성은 1차사출성형 및 2차사출성형에 의해 선택적으로 행해질 수 있으므로 본 예시에서 설명하지 않은 부분에도 얼마든지 강화부는 형성될 수 있다.As described above, since the reinforcement parts 213a and 221a may be selectively formed by the first injection molding and the second injection molding, for example, the reinforcing injection parts 222a and 223a are supplied to the curved parts 213. The reinforcement part 213a may be formed, and the reinforcement part 220a may be formed at one end of the body part 120, which may be connected to a separate member. As such, the formation of the reinforcement parts 213a and 220a may be selectively performed by the first injection molding and the second injection molding, and thus, the reinforcement parts may be formed in any portion not described in the present example.
한편, 강화부(213a, 220a)는 프레임(10)의 저면 및 상면에 두 차례에 걸쳐 강화될 수 있다. 프레임(10)의 바디부(120)의 저면에는 1차강화물(222a)이 주입되어 프레임(10)과 결합된다면, 2차강화물(223a)이 바디부(120)의 상면에 주입되어 프레임(10)과 결합될 수 있다. 앞서 설명한 바와 같이 이때의 버스바의 두께는 1 mm 내지 1.5mm 가 될 수 있다. 또한 1차강화물(222a)과 2차강화물(223a)은 서로 다른 재질이 될 수 있으며, 적어도 하나의 재질은 수지가 될 수 있다.Meanwhile, the reinforcement parts 213a and 220a may be strengthened twice on the bottom and the top surface of the frame 10. If the primary reinforcement 222a is injected into the bottom surface of the body portion 120 of the frame 10 and coupled to the frame 10, the secondary reinforcement 223a is injected into the upper surface of the body portion 120 to provide a frame 10. ) May be combined. As described above, the thickness of the bus bar at this time may be 1 mm to 1.5 mm. In addition, the primary reinforcement 222a and the secondary reinforcement 223a may be different materials, and at least one material may be resin.
도 4는 본 발명의 다른 실시예에 따른 프레임(30) 및 금형(1)의 일부구조에 대한 도면으로서, 도 4(a)는 본 발명의 다른 실시예에 따른 프레임(30)의 사시도, 도 4(b)는 본 발명의 일 실시예에 따른 금형에 형성되는 돌출부(2)이다.4 is a view of a partial structure of the frame 30 and the mold 1 according to another embodiment of the present invention, Figure 4 (a) is a perspective view of the frame 30 according to another embodiment of the present invention, 4 (b) is a protrusion 2 formed in a mold according to an embodiment of the present invention.
도 4(a)를 참조하면, 프레임(30)은 앞서 설명한 프레임(10)에 가이드(330)를 더 포함할 수 있다. 가이드(330)는 1차사출성형 및 2차사출성형 시에 금형(1) 내에서 강화주입물이 공급될 때 프레임(30)이 이동되지 않도록 고정시키는 구조로서, 1차사출성형 및 2차사출성형 시에는 금형(1) 내에 위치될 수 있다. 예를 들면, 가이드(330)는 금형(1) 내측에 위치된 프레임(30)의 일부가 이동되지 않고 고정될 수 있도록 할 수 있다.Referring to FIG. 4A, the frame 30 may further include a guide 330 in the frame 10 described above. The guide 330 is a structure for fixing the frame 30 so that the frame 30 does not move when the reinforcing injection is supplied in the mold 1 during the first injection molding and the second injection molding. It may be located in the mold 1 during molding. For example, the guide 330 may allow a portion of the frame 30 located inside the mold 1 to be fixed without being moved.
가이드(330)와 일체형으로 형성된 구조인 프레임(30)은 금형 내에서 노치부(330a)에 의해 연결될 수 있다. 상기 노치부(330a)는 2차사출성형 후에 절단 등의 방법으로 프레임(30)으로부터 가이드(330)가 분리될 수 있다. 즉, 노치부(330a)는 프레임(30)이 금형(1) 내에서 이동되지 않고 고정될 수 있도록 하되, 2차사출성형이 끝나면 가이드(330)의 분리가 용이하도록 연결면적이 작게 형성되는 것이 바람직하다.The frame 30 having a structure integrally formed with the guide 330 may be connected by the notch 330a in the mold. The notch 330a may be separated from the frame 30 by the cutting method after the secondary injection molding. That is, the notch part 330a allows the frame 30 to be fixed without moving in the mold 1, but when the second injection molding is completed, the connection area is formed small so that the guide 330 can be easily separated. desirable.
또한, 상기 고정을 위해 가이드(330)에는 핀홀(331)이 형성될 수 있다. 프레임(30)이 고정되기 위해 가이드(331)가 고정될 수 있는데 핀홀(331)은 금형에 형성된 핀과 결합되어 고정될 수 있다. 따라서, 핀홀(331)은 두 개 형성될 수 있다. 물론, 고정을 위한 구조이므로 이는 원형인 경우에 한하며, 사각형 등의 각형의 홀인 경우에는 하나 이상의 홀이 형성될 수도 있다.In addition, a pinhole 331 may be formed in the guide 330 for the fixing. The guide 331 may be fixed so that the frame 30 is fixed, and the pinhole 331 may be fixed by being combined with a pin formed in the mold. Therefore, two pinholes 331 may be formed. Of course, it is a structure for fixing, so this is only a circular case, in the case of a rectangular hole such as a square may be formed one or more holes.
도 4(b)를 참조하면, 금형(1) 내에 프레임(10)의 다른 고정방법으로서, 금형(1) 내에 돌출부(2)가 형성되고, 돌출부(2)와 대응되는 홈이 프레임(10)에 형성될 수 있다. 상기 돌출부(2)는 프레임(10)을 가압하기 위한 구조로서, 상기 홈과 대응되도록 형성되지 않더라도, 상기 프레임(10)의 면과 접촉되어 프레임(10)을 지지할 수 있다. 하나의 실시예로서, 상기 돌출부(2)는 금형(1)으로부터 돌출되되, 금형(1)과는 탄성체(3)를 사이에 두고 배치될 수 있다. 즉, 프레임(10)를 고정하기 위해 금형(1)으로부터 돌출된 방향으로 탄성체(3)에 돌출부(2)는 프레임(10)를 가압할 수 있다.Referring to FIG. 4B, as another fixing method of the frame 10 in the mold 1, a protrusion 2 is formed in the mold 1, and a groove corresponding to the protrusion 2 is formed in the frame 10. Can be formed on. The protrusion 2 is a structure for pressing the frame 10, and may be in contact with the surface of the frame 10 to support the frame 10 even though it is not formed to correspond to the groove. As an example, the protrusion 2 may protrude from the mold 1, and may be disposed with the mold 1 with an elastic body 3 interposed therebetween. That is, in order to fix the frame 10, the protrusion 2 may press the frame 10 on the elastic body 3 in the direction protruding from the mold 1.
도 5는 본 발명의 다른 실시예들에 따른 버스바(40, 50, 60)를 나타낸 도면으로서, 도 5(a)는 ““ㄷ””자 형태의 버스바(40), 도 5(b)는 ““ㄱ””자 형태의 버스바(50), 도 5(c)는 ““2””자 형태의 버스바(60)를 나타낸 도면이다. 본 예시는 버스바(40, 50, 60)의 형태에 있어서, 다양한 예를 개시하기 위한 것이다.FIG. 5 is a diagram illustrating bus bars 40, 50, and 60 according to other embodiments of the present invention, and FIG. 5 (a) shows a bus bar 40 having a “C” shape and FIG. 5 (b). ) Is a bus bar 50 in the form of “a”, and FIG. 5 (c) is a view of the bus bar 60 in the form of “2”. This example is intended to disclose various examples in the form of busbars 40, 50, 60.
도 6을 참조하면, 상기 버스바(40, 50, 60)는 양단에 센싱부(410, 510, 610)가 각각 위치되고 각 센싱부(410, 510, 610) 사이에 바디부(420, 520, 620)가 위치되는 예로서, 바디부(420, 520, 620)의 절곡은 다양하게 형성될 수 있다. Referring to FIG. 6, the bus bars 40, 50, and 60 have sensing parts 410, 510, and 610 located at both ends, respectively, and body parts 420 and 520 between the sensing parts 410, 510, and 610. As an example in which 620 is positioned, bending of the body parts 420, 520, and 620 may be variously formed.
나아가, 여기서 인서트 사출을 통해 제조되는 버스바(20, 40, 50, 60)는 비철금속으로 형성될 수 있으며, 예를 들어, 상기 비철금속은 알루미늄 또는 동 등이 될 수 있다. 그리고, 제조된 버스바(20, 40, 50, 60)는 강화주입물(222a, 223a)에 의한 강화를 통해 바디부(200) 및 연결부(100)의 두께가 강화부(도 3의 213a, 221a)에 의해 차이나도록 형성될 수 있다. 이러한 차이에 의해 탄성을 결정할 수 있다.In addition, the bus bars 20, 40, 50, and 60 manufactured by insert injection may be formed of a nonferrous metal. For example, the nonferrous metal may be aluminum or copper. In addition, the manufactured bus bars 20, 40, 50, and 60 have a thickness of the body part 200 and the connection part 100 through the reinforcement by the reinforcing injection parts 222a and 223a (213a of FIG. 3). 221a) may be formed to be different. This difference can determine elasticity.
또한, 강화주입물(222a, 223a)에 의해 프레임(10)에 1차강화주입물 주입(S2) 및 2차강화주입물 주입(S3)이 행해진 버스바(20, 40, 50, 60)는 센싱부(210, 410, 510, 610)가 니켈 또는 주석 등에 의해 표면처리가 될 수 있다. 상기 표면 처리뿐 아니라, 센싱부(210, 410, 510, 610)는 니켈, 금, 구리 및 주석 중 적어도 어느 하나를 포함한 도금층을 형성하며 이루어질 수 있다.In addition, the bus bars 20, 40, 50, and 60 in which the primary reinforcement injection S2 and the secondary reinforcement injection S3 are performed in the frame 10 by the reinforcement injections 222a and 223a, respectively. The sensing units 210, 410, 510, and 610 may be surface treated by nickel or tin. In addition to the surface treatment, the sensing units 210, 410, 510, and 610 may be formed by forming a plating layer including at least one of nickel, gold, copper, and tin.
그리고, 프레임(10, 30)는 1차사출성형 및 2차사출성형 시에 주입되는 강화주입물(222a, 223a)에 의해 밀착력을 증진시키기 위해 프레임(10, 30)은 프레임(1)과 접촉되는 외표면에 비정형부가 형성될 수 있다. 상기 비정형부란, 균일하지 않고 거칠거나, 돌기 또는 요철형상을 포함하며, 홀, 스파이크 및 드로윙 중 하나 이상을 포함한다. 상기 비정형부 측으로 강화주입물(222a, 223a)이 주입되어 경화된 후에는 프레임(10, 30)과 강화주입물(222a, 223a)의 결합력은 더욱 증가될 수 있다.In addition, the frames 10 and 30 are in contact with the frame 1 in order to enhance adhesion by the reinforcement injections 222a and 223a injected during the primary injection molding and the secondary injection molding. Atypical portions may be formed on the outer surface. The atypical portion may be non-uniform and rough, include protrusions or irregularities, and include one or more of holes, spikes and drawing. After the reinforcement injections 222a and 223a are injected into the atypical portion and cured, the coupling force between the frames 10 and 30 and the reinforcement injections 222a and 223a may be further increased.
또한, 전류의 흐름에 의해 발열될 수 있는 바디부(120, 320)는 2차사출성형 시에 강화주입물(222a, 223a)의 주입이 일면과 타면에 비대칭적으로 행해짐으로써, 강화를 위한 강화부는 바디부(120, 320)의 일면측에만 형성될 수 있다. 따라서, 상기 강화부가 형성되지 않은 바디부(120, 320)의 타면측에는 외측으로 노출될 수 있으므로 상기 발열에 의한 열이 방열되기에 유리할 수 있다.In addition, the body parts 120 and 320, which may be generated by the flow of electric current, are injected asymmetrically on one side and the other side of the reinforcement injections 222a and 223a during the second injection molding, thereby strengthening for reinforcement. The part may be formed only on one surface side of the body parts 120 and 320. Therefore, the other surface side of the body parts 120 and 320 in which the reinforcement part is not formed may be exposed to the outside, and thus may be advantageous to dissipate heat due to the heat generation.
또한, 상기 강화주입물에 의해 형성된 강화부는 센싱부(110, 210, 310, 410, 510, 610)를 제외한 위치에 위치될 수도 있다. 상기 강화물에 의해 두꺼워진 부분은 버스바(20, 40, 50, 60)에서 전류의 흐름방향의 단면적 및 외표면적이 증대되어 전기전도율 및 방열성이 향상될 수 있다. 그리고, 상기 센싱부(110, 210, 310, 410, 510, 610)는 도금이 될 수 있는데, 도금은 금, 은, 니켈, 아연 및 주석 등을 적어도 하나 이상 포함할 수 있고, 도금에 의해 전기전도성은 더욱 증가될 수 있다.In addition, the reinforcement portion formed by the reinforcement injection may be located at positions other than the sensing units 110, 210, 310, 410, 510, 610. The portion thickened by the reinforcement may increase the cross-sectional area and the outer surface area of the flow direction of the current in the bus bars 20, 40, 50, and 60, thereby improving electrical conductivity and heat dissipation. In addition, the sensing units 110, 210, 310, 410, 510, and 610 may be plated. Plating may include at least one or more of gold, silver, nickel, zinc, tin, and the like. The conductivity can be further increased.
도 6은 본 발명의 다른 실시예에 따른 적층형 버스바(70)의 형상을 나타낸 도면이다. 도 6에서는 프레임을 2 개 적층된 경우를 예시적으로 설명하나, 3 개 이상이 적층되는 경우에도 이하의 설명에 적용될 수 있다.6 is a view showing the shape of the stacked bus bar 70 according to another embodiment of the present invention. In FIG. 6, a case in which two frames are stacked is described as an example. However, even when three or more frames are stacked, the present invention may be applied to the following description.
도 6을 참조하면, 프레임을 복수 개 적층시킨 상태에서 인서트 사출을 행하는 실시예가 될 수 있다. 예를 들어, 프레임을 복수 개 적층시킨 형태로서 각 프레임의 바디부(42; 421a, 421b) 및 각 연결부(412a, 412b)가 적층되고 적층된 프레임은 금형에 인서트되어 사출성형될 수 있다.Referring to FIG. 6, it may be an embodiment in which insert injection is performed while a plurality of frames are stacked. For example, a plurality of frames are stacked, and the body parts 42 and 421a and 421b and the connecting parts 412a and 412b of each frame are stacked, and the stacked frames may be inserted into a mold and injection molded.
여기서, 사출성형 시에 주입되는 1차강화물(222a) 및 2차강화물(223a)은 적층된 프레임의 하면 및 상면에 각각 주입될 수 있다. 두 개의 프레임이 적층된 본 예시의 경우에 하측에 위치된 바디부(42; 421b)에 1차강화물(222a)이 공급될 수 있고, 2차강화물은 상측에 위치된 바디부(42; 421a)에 공급될 수 있다. 여기서 강화물(222a, 223a)은 적층된 프레임의 노출면적 중 일부 또는 전체에 주입될 수 있다.Here, the primary reinforcement 222a and the secondary reinforcement 223a to be injected during injection molding may be injected to the lower and upper surfaces of the stacked frames, respectively. In the present example in which two frames are stacked, the primary reinforcement 222a may be supplied to the lower body parts 42 and 421b, and the secondary reinforcement may be provided to the upper body parts 42 and 421a. Can be supplied to. The reinforcements 222a and 223a may be injected into some or all of the exposed areas of the stacked frames.
상기 일부에 강화물(222a, 223a)이 주입되는 경우에는 예를 들어, 평면부에 공급될 수 있다. 상기 평면부는 상기 만곡부(423a, 413a, 413b)를 제외한 골부(421a, 421b) 및 요부(422a) 등을 포함할 수 있다. 강화물(222a, 223a)이 주입되는 부분은 앞선 실시예와 같이 내구력을 향상시키기 위한 목적 등으로 행해질 수 있다.When the reinforcements 222a and 223a are injected into the portion, for example, the reinforcements 222a and 223a may be supplied to the flat portion. The planar portion may include bone portions 421a and 421b and recessed portions 422a and the like except for the curved portions 423a, 413a, and 413b. Portions into which the reinforcements 222a and 223a are injected may be performed for the purpose of improving durability, as in the previous embodiment.
나아가, 강화물(222a, 223a)이 주입되는 면적은 적층된 프레임의 측면을 더 포함할 수 있다. 복수 개의 프레임을 적층 후 측면을 포함한 면을 강화물(222a, 223a)을 주입하여 사출함으로써 각 프레임 간 결합이 이루어질 수 있다. 상기 강화물(222a, 223a)에 의한 결합 외에도 각 프레임 간의 레이저 용접을 포함한 용접 및 접착제에 의해 서로 접촉된 결합상태를 유지할 수 있다.Furthermore, the area into which the reinforcements 222a and 223a are injected may further include side surfaces of the stacked frames. After stacking a plurality of frames by injecting the reinforcing material (222a, 223a) to the surface including the side may be combined between each frame. In addition to the coupling by the reinforcement (222a, 223a) can be maintained in contact with each other by welding and adhesive, including laser welding between each frame.
또한, 각 프레임이 서로 강화물(222a, 223a)에 의해 결합이 행해질 경우에는 각 프레임 간에는 상기 강화물(222a, 223a)의 유입이 차단될 수 있다. 따라서, 적층된 프레임이 금형에 삽입될 때 강화물(222a, 223a)이 각 프레임 사이로 주입되지 않도록 서로 밴딩 등과 같은 가압수단에 의해 서로 가압되어 행해질 수가 있다.In addition, when the frames are coupled to each other by the reinforcements 222a and 223a, inflow of the reinforcements 222a and 223a may be blocked between the frames. Therefore, when the laminated frames are inserted into the mold, the reinforcements 222a and 223a may be pressed against each other by pressing means such as bending each other so as not to be injected between the frames.
