상기 복수 개의 전기소자(10,20,30)는 상기 지지플레이트(110,210,310)의 일면에 장착될 수 있으며, 상기 부스바(120)를 매개로 서로 전기적으로 연결될 수 있다. 이를 통해, 상기 전기소자(10,20,30)는 배터리로부터 공급된 고전압전류를 구동제어부 측으로 차단하거나 연결하는 역할을 수행할 수 있다.The plurality of electric devices 10, 20, and 30 may be mounted on one surface of the support plates 110, 210, and 310 and may be electrically connected to each other through the bus bar 120. Accordingly, the electric devices 10, 20, and 30 may block or connect the high voltage current supplied from the battery to the driving control unit.
이와 같은 전기소자들(10,20,30)은 메인 릴레이, 프리차지 릴레이, 프리차지 레지스터, 배터리 전류센서, 메인퓨즈 등일 수 있으며, 상기 부스바(120)나 케이블(미도시)을 매개로 서로 전기적으로 연결될 수 있다. 또한, 상기 복수 개의 부스바(120)들은 상기 지지플레이트(110,210,310)에 형성되는 회로패턴(미도시)들을 통해 전기적으로 연결될 수도 있다.The electric devices 10, 20 and 30 may be a main relay, a precharge relay, a precharge resistor, a battery current sensor, a main fuse, and the like, and may be connected to each other via the busbar 120 or a cable And can be electrically connected. Also, the plurality of bus bars 120 may be electrically connected through circuit patterns (not shown) formed on the support plates 110, 210, and 310.
이를 통해, 상기 전기소자들(10,20,30)은 배터리로부터 공급된 고전압전류를 차단 또는 연결하여 구동전압을 제어하는 구동제어부(미도시) 측에 전력을 공급함으로써 상기 구동제어부에서 모터를 구동하기 위한 제어신호를 생성할 수 있다. 이때, 상기 구동제어부는 모터 구동을 위한 제어신호를 생성할 수 있으며, 제어신호를 통해 인버터 및 컨버터를 제어함으로써 모터의 구동이 제어될 수 있다.Accordingly, the electric elements 10, 20, and 30 supply electric power to the drive control unit (not shown) for controlling the drive voltage by interrupting or connecting the high voltage current supplied from the battery, Can be generated. At this time, the drive control unit can generate a control signal for driving the motor, and the driving of the motor can be controlled by controlling the inverter and the converter through the control signal.
일례로, 차량의 운전시에는 메인 릴레이가 접속상태가 되고, 프리 차지 릴레이가 차단되므로 메인 회로를 통하여 배터리의 전력이 인버터로 인가될 수 있다.For example, when the vehicle is in operation, the main relay is connected and the precharge relay is cut off, so that the power of the battery can be applied to the inverter through the main circuit.
또한, 차량의 off 시에는 메인 릴레이가 차단상태가 되고, 배터리와 인버터의 접속이 차단됨으로써 배터리 전압이 인버터를 통해 모터로 전달되는 것이 방지될 수 있다. 이때, 상기 메인 릴레이가 차단 상태인 경우에는 인버터에 접속된 콘덴서가 방전될 수 있다.Further, when the vehicle is off, the main relay is in a cut-off state, and the connection between the battery and the inverter is cut off, thereby preventing the battery voltage from being transmitted to the motor through the inverter. At this time, when the main relay is in the off state, the capacitor connected to the inverter may be discharged.
이후, 차량을 다시 운전하는 경우에는 프리 차지 릴레이가 접속되어 배터리의 전압이 프리 차지 저항에 의해 강하된 상태로 인버터에 인가됨으로써 콘덴서의 충전이 개시될 수 있다. 그런 다음, 콘덴서가 충분히 충전되면 메인 릴레이가 접속됨과 동시에 프리 차지 릴레이가 차단됨으로써 배터리의 전압이 인버터에 인가될 수 있다.Thereafter, when the vehicle is operated again, the precharge relay is connected, and the voltage of the battery is applied to the inverter in a state of being lowered by the precharge resistor, so that charging of the capacitor can be started. Then, when the capacitor is sufficiently charged, the main relay is connected and at the same time, the precharge relay is cut off so that the voltage of the battery can be applied to the inverter.

As a specific example, the fixing members 140 and 240 may be elastic members that are elastically deformed as shown in FIGS. 8 to 11, and one end of the clip member is in contact with the upper surface of the contact unit 121 .
이에 따라, 상기 접촉부(121)는 상기 고정부재(140,240)를 통해 일면이 상기 지지플레이트(110)와 접촉된 상태를 유지함으로써 상기 부스바(120)가 지지플레이트(110)로부터 분리되는 것이 방지될 수 있다.The contact portion 121 is kept in contact with the support plate 110 through the fixing members 140 and 240 so that the busbar 120 is prevented from being separated from the support plate 110 .

Here, a guide member 342 protruding to guide the position of the contact portion 121 may be provided on one side of the support plate 110.
그러나, 상기 고정부재를 이에 한정하는 것은 아니며 공지의 핀부재가 사용될 수도 있으며, 도 8 내지 도 13에 도시된 고정부재들이 서로 조합된 형태일 수도 있다. 더불어, 도 8 내지 도 13에 도시된 지지플레이트(110)는 도 5 내지 도 7에 도시된 지지플레이트(210,310)가 적용될 수도 있다.However, the fixing member is not limited thereto, and a known pin member may be used, and the fixing members shown in Figs. 8 to 13 may be combined with each other.

한편, 본 발명에 따른 파워 릴레이 어셈블리(100)는 보호코팅층(150)을 더 포함할 수 있다.Meanwhile, the power relay assembly 100 according to the present invention may further include a protective coating layer 150.
일례로, 상기 보호코팅층(150)은 도 4 내지 도 7에 도시된 바와 같이 상기 지지플레이트(110,210,310) 및 부스바(120)의 외부면을 모두 덮도록 구비될 수 있다. 또한, 상기 보호코팅층(150)은 상기 지지플레이트(110,210,310)의 일면에 장착되는 전기소자들(10,20,30)의 외부면 역시 모두 덮을 수 있다. 그러나 상기 보호코팅층(150)의 도포 위치를 이를 한정하는 것은 아니며, 지지플레이트(110,210,310)의 외부면에만 도포될 수도 있고, 부스바(120)의 외부면에만 도포되는 것도 가능하다. 또한, 상기 보호코팅층(150)은 도 8 내지 도 13에 도시된 지지플레이트(110)에도 동일하게 적용될 수 있다.For example, the protective coating layer 150 may cover the outer surfaces of the support plates 110, 210, and 110 and the bus bar 120 as shown in FIGS. Also, the protective coating layer 150 may cover the outer surfaces of the electric elements 10, 20, and 30 mounted on one side of the support plates 110, 210, and 310. However, the application position of the protective coating layer 150 is not limited thereto, and it may be applied only to the outer surface of the support plates 110, 210 and 310, or may be applied only to the outer surface of the busbar 120. Also, the protective coating layer 150 may be applied to the support plate 110 shown in FIGS.
이와 같은 보호코팅층(150)은 지지플레이트(110,210,310) 및 부스바(120)의 표면에 가해지는 물리적 자극으로 인한 스크래치 등을 방지할 수 있으며, 표면의 절연성을 더욱 향상시킬 수 있다.Such a protective coating layer 150 can prevent scratches and the like due to physical stimulation applied to the surfaces of the support plates 110, 210, and 310 and the bus bar 120, and further improve the insulation of the surface.
또한, 상기 보호코팅층(150)은 상술한 지지플레이트(110,210,310)가 절연성 방열필러가 분산된 플라스틱으로 이루어진 경우 표면에 위치한 절연성 방열필러의 이탈을 방지하는 역할을 수행할 수도 있다. In addition, the protective coating layer 150 may prevent the separation of the insulating heat-dissipating filler located on the surface when the support plates 110, 210, and 310 are formed of plastic in which the insulating heat-dissipating filler is dispersed.
일례로, 상기 보호코팅층(150)은 공지된 열경화성 고분자화합물 또는 열가소성 고분자화합물로 구현될 수 있다. 상기 열경화성 고분자화합물은 에폭시계, 우레탄계, 에스테르계 및 폴리이미드계 수지로 이루어진 군에서 선택된 1종의 화합물, 또는 2종 이상의 혼합물 또는 코폴리머일 수 있다. 또한, 상기 열가소성 고분자화합물은 폴리아미드, 폴리에스테르, 폴리케톤, 액정고분자, 폴리올레핀, 폴리페닐렌설파이드(PPS), 폴리에테르에테르케톤(PEEK), 폴리페닐렌옥사이드(PPO), 폴리에테르술폰(PES), 폴리에테르이미드(PEI) 및 폴리이미드로 이루어진 군에서 선택된 1종의 화합물, 또는 2종 이상의 혼합물 또는 코폴리머일 수 있으나 이에 제한되는 것은 아니다.For example, the protective coating layer 150 may be formed of a known thermosetting polymer compound or a thermoplastic polymer compound. The thermosetting polymer compound may be one kind of compound selected from the group consisting of epoxy type, urethane type, ester type and polyimide type resins, or a mixture or copolymer of two or more kinds. The thermoplastic polymer compound may be at least one selected from the group consisting of polyamides, polyesters, polyketones, liquid crystal polymers, polyolefins, polyphenylene sulfide (PPS), polyetheretherketone (PEEK), polyphenylene oxide (PPO) ), A polyetherimide (PEI), and a polyimide, or a mixture or copolymer of two or more kinds, but is not limited thereto.
한편, 상기 보호코팅층(150)은 상술한 지지플레이트(110,210,310)의 외부면에 도포됨으로써 상기 지지플레이트(110,210,310) 측으로 전달된 열이 외부로 방출되는 것을 방해할 수 있다. 이를 해결하기 위하여, 상기 보호코팅층(150)은 외부로의 열 방사특성을 향상시킬 수 있도록 절연성 방열필러를 더 포함할 수도 있다. 상기 절연성 방열필러는 공지된 절연성 방열필러의 경우 제한 없이 사용될 수 있다. Meanwhile, the protective coating layer 150 is applied to the outer surfaces of the support plates 110, 210, and 310 to prevent the heat transmitted to the support plates 110, 210, and 310 from being emitted to the outside. In order to solve this problem, the protective coating layer 150 may further include an insulating heat-radiating filler so as to improve heat radiation characteristics to the outside. The insulating heat-dissipating filler can be used without limitation in the case of a known insulating heat-dissipating filler.
일례로, 상기 보호코팅층(150)은 상술한 지지플레이트(110,210,310)와 마찬가지로 방열성 및 절연성을 동시에 갖도록 고분자매트릭스에 분산되는 절연성 방열필러를 포함할 수 있다.For example, the protective coating layer 150 may include an insulating heat-radiating filler dispersed in a polymer matrix so as to have heat dissipation and insulation properties at the same time as the support plates 110, 210, and 310 described above.
이때, 상기 보호코팅층(150)에 포함된 절연성 방열필러는 상기 지지플레이트(110,210,310)에 포함된 절연성 방열필러와 동일한 종류가 사용될 수도 있고 상이한 종류가 사용될 수도 있다.At this time, the insulating heat-radiating filler included in the protective coating layer 150 may be the same as or different from the insulating heat-radiating filler included in the support plates 110, 210, and 310.
상기 부스바(120)는 상술한 바와 같이 낮은 임피던스와 높은 전류용량을 갖는 도체로 형성될 수 있다. 구체적인 일례로써, 상기 부스바(120)는 구리나 알루미늄과 같은 금속재질로 이루어질 수 있다.The bus bar 120 may be formed of a conductor having a low impedance and a high current capacity as described above. As a specific example, the bus bar 120 may be made of a metal such as copper or aluminum.
여기서, 상기 부스바(120)가 알루미늄 재질로 이루어진 경우, 상기 부스바(120)는 도 13에 도시된 바와 같이 방열코팅층(C)이 표면에 도포된 형태일 수 있으며, 상기 방열코팅층(C)은 상술한 절연성 방열필러를 포함하는 보호코팅층(150)과 동일한 것일 수 있다. 즉, 알루미늄 재질로 이루어진 부스바(120)는 구리 재질로 이루어진 부스바(120)에 비하여 가벼운 무게를 가질 수 있다. 이는, 재료의 특성상 알루미늄이 구리보다 상대적으로 비중이 작기 때문이다. 이에 따라, 상기 부스바(120)의 재질을 알루미늄으로 사용한 파워 릴레이 어셈블리는 상기 부스바(120)의 재질로 구리를 사용한 파워 릴레이 어셈블리보다 매우 가벼운 중량을 가질 수 있다.When the bus bar 120 is made of aluminum, the bus bar 120 may be formed by coating the surface of the heat dissipation coating layer C on the surface of the heat dissipation coating layer C, May be the same as the protective coating layer 150 including the above-described insulating heat-dissipating filler. That is, the bus bar 120 made of an aluminum material can have a light weight as compared with the bus bar 120 made of a copper material. This is because aluminum has a relatively smaller specific gravity than copper due to the characteristics of the material. Accordingly, the power relay assembly using aluminum as the material of the bus bar 120 may be much lighter than the power relay assembly using the copper as the material of the bus bar 120.
반면, 재료의 특성상 알루미늄이 구리보다 상대적으로 열전도도가 작기 때문에 동일한 사이즈로 제작되는 경우 방열성능이 떨어질 수 있으며, 동등한 수준의 방열성능을 구현하기 위해서는 부스바의 두께를 두껍게 제작해야하는 단점이 있다.On the other hand, when aluminum is made of the same size as the aluminum, the aluminum has a smaller thermal conductivity than copper, and the heat dissipation performance may be lowered. In order to achieve an equivalent level of heat dissipation performance, the thickness of the bus bar must be increased.
본 발명에서는 이러한 문제점을 해결하기 위하여 상기 부스바(120)가 알루미늄 재질로 이루어진 경우 부스바(120)의 표면에 절연성 방열필러를 포함하는 방열코팅층(C)을 형성하여 방열성능을 보완함으로써 상기 부스바가 구리재질로 이루어진 경우에 비하여 증가되는 두께를 최소화하면서도 동등 수준의 방열성능을 구현할 수 있다.In order to solve this problem, in the present invention, if the booth bar 120 is made of aluminum, a heat radiation coating layer C including an insulating heat radiation filler is formed on the surface of the booth bar 120, The heat dissipation performance of the same level can be realized while minimizing the increased thickness as compared with the case where the bar is made of copper material.
이에 따라, 상기 부스바(120)의 재질을 알루미늄으로 사용한 파워 릴레이 어셈블리는 상기 부스바(120)의 재질로 구리를 사용한 파워 릴레이 어셈블리에 비하여 경량화로 구현할 수 있으며, 생산 원가를 절감할 수 있다.Accordingly, the power relay assembly using aluminum as the material of the bus bar 120 can be realized in a weight reduction compared to the power relay assembly using copper as the material of the bus bar 120, and the production cost can be reduced.
비제한적인 예로써, 알루미늄 재질로 이루어진 부스바는 동일한 형상을 갖는 구리재질로 이루어진 부스바에 비하여 동등 수준의 방열성능을 구현하기 위해서는 대략 1.5배의 두께로 제작되어야 한다. 그러나 상기 부스바의 표면에 절연성 방열필러를 포함하는 방열코팅층(C)이 형성되는 경우, 즉, 알루미늄 재질로 이루어지고 표면에 절연성 방열필러를 포함하는 방열코팅층(C)이 형성된 부스바는 구리재질로 이루어진 부스바와 비교할 때 대략 1.3배의 두께를 갖더라도 동등 수준의 방열성능을 구현할 수 있다.As a non-limiting example, a booth bar made of aluminum material should be about 1.5 times thicker than a booth bar made of copper material having the same shape to achieve the same level of heat radiation performance. However, when the heat-radiating coating layer (C) including the insulating heat-radiating filler is formed on the surface of the busbars, that is, the busbars formed of the aluminum material and having the heat-radiating coating layer (C) It is possible to achieve an equivalent level of heat dissipation performance even if the thickness of the bus bar is approximately 1.3 times as thick as that of the conventional bus bar.
그러나 상기 부스바(120)의 재질을 이에 한정하는 것은 아니며, 낮은 임피던스와 높은 전류용량을 갖는 도체라면 제한없이 사용될 수 있다.However, the material of the bus bar 120 is not limited thereto, and any conductor having low impedance and high current capacity can be used without limitation.

In addition, the cover 130 may be in the form of a box with one side opened.

또한, 상기 커버(130)는 절연성을 갖는 일반 플라스틱 재질로 이루어질 수 있지만, 적어도 일부가 상술한 지지플레이트(110,210,310)와 마찬가지로 방열성 및 절연성을 갖는 플라스틱 재질로 이루어질 수 있다.The cover 130 may be made of a general plastic material having insulation properties, but at least a part of the cover 130 may be made of a plastic material having heat dissipation and insulation properties like the support plates 110, 210, and 310 described above.
