Abstract

A fuse and relay insertion height control device (10) used for inserting a fuse and a relay into a relay retainer assembly (12) comprises a shielding cover member (20), a pressing pin (34), a spring (36), and a switch (44). The shielding cover member (20) is used for defining multiple openings (22), and each opening (24) is configured to align the fuse or the relay (14) to an accommodating base (16) of the relay retainer assembly (12). The pressing pin (34) is used for pressing the fuse or the relay (14) into the accommodating base (16). The spring (36) is used for pressing, by using a keeping force (40), the pressing pin (34) to face to a mounting position (38). The keeping force (40) is a force greater than an insertion force (42) needed to press the fuse or the relay (14) into the accommodating base (16) when the fuse or relay (14) is aligned to the accommodating base (16). The switch (44) is used for detecting when the pressing pin (34) is forced to be leave away from the mounting position (38), so as to indicate that the fuse or the relay (14) is not aligned to the accommodating base (16).

Description

Fuse and relay insertion height control

Technical field

The present disclosure generally relates to a fuse and relay insertion height control device, and more particularly to a switch for detecting when a spring force is overcome thereby causing the pin to be forced away from the set position, thereby indicating a fuse or The relay is not aligned with the receptacle of the fuse holder assembly.

Background technique

It is known that manually inserting a fuse or relay into a fuse holder assembly may result in an inconsistent height of the fuse or relay. However, machines that exert a strong force to press a fuse or relay into the fuse holder assembly may irreparably damage one or more receptacles of the fuse holder assembly, thereby causing undesirable scrap.

Summary of the invention

According to one embodiment, a fuse and relay insertion height control device for inserting fuses and relays into a fuse holder assembly is provided. The device includes a cover, a pin, a spring, and a switch. The cover is used to define a plurality of openings. Each opening is configured to align the fuse or relay with the receptacle of the fuse holder assembly. The pin is used to press the fuse or relay into the receptacle. The spring forces the pin to face the set position using a retaining force. The retention force is selected to be greater than the insertion force required to press the fuse or relay into the receptacle when the fuse or relay is aligned with the receptacle. The switch is for detecting when the pin is forced away from the set position, thereby indicating that the fuse or relay is not aligned with the receptacle.

Further features and advantages will be more apparent from the following detailed description of the preferred embodiments.

detailed description

FIG. 1 illustrates a non-limiting example of a fuse and relay insertion height control device 10, hereinafter referred to as device 10. In general, device 10 is used to insert fuses and relays into fuse holder assembly 12. By way of example, and without limitation, fuse holder assembly 12 may be a fuse holder assembly used in a car or other vehicle to provide a central location for a fuse of a power distribution system in an automobile. As will be explained in more detail below, the device 10 described herein is an improvement to the manual insertion embodiment because the fuses and/or relays are inserted into the final product, ie, the fuse holder assembly 12, to be uniform or Scheduled height. Moreover, the apparatus 10 described herein has a means for detecting when an instance of the fuse or relay 14 (Fig. 2) is improperly aligned for insertion into an instance of the intended fuse or relay to be received/held in the fuse. Within the receptacle 16 of the fuse holder assembly 12 in the assembly 12. In this non-limiting example of device 10, handle 18 is provided for pressing fuse or relay 14 into fuse holder assembly 12, i.e., operating device 10. It is contemplated that the handle 18 can be replaced with, for example, a pneumatic, electric or hydraulic actuator.

Device 10 includes a cover 20 that defines a plurality of openings 22. Each opening 24 (i.e., each individual instance of the plurality of openings 22) is configured to receive an instance of a fuse or relay 14 and to provide an example of a fuse or relay 14 with a desired instance of the receptacle 16 of the fuse holder assembly 12. Align. That is, the fuse or relay 14 is loaded into the cover 20 before the fuse or relay 14 is inserted or mounted into the receptacle 16. The opening 24 is sized such that it can rely on the body portion 26 of the fuse or relay 14 to align the terminal portion 28 of the fuse or relay 14 with the receptacle 16 prior to insertion. Although the configuration of the device 10 illustrated in FIG. 1 may indicate that each instance of the fuse or relay 14 may be manually loaded into the cover 20 prior to operation of the device 10, it is contemplated that the loading of the cover 20 may be utilized. Pick and place techniques that are common in board manufacturing processes are automated.

Referring again to FIG. 1, when the handle 18 is operated, the pressure box 30 is lowered and the plurality of press pins 32 are in contact with an instance of the fuse or relay 14, and then an instance of the fuse or relay 14 is pressed into place. Fuse holder assembly 12.

2-5 illustrate further non-limiting details of the pressure box 30 that includes a pressure pin 34 (ie, a single one of the plurality of pressure pins 32) that is depressed when the pressure box 30 is lowered toward the cover member 20. Press the fuse or relay 14 into the receptacle 16). 2 shows the position of the pressure box 30 similar to that shown in FIG. 1 before the actuation of the handle 18 to lower the pressure box toward the cover 20. FIG. 3 shows the press pin 34 that has made initial contact with the fuse or relay 14 and begins to press the fuse or relay 14 into the receptacle 16. FIG. 4 shows an example when the fuse or relay 14 has been completely disposed within the fuse holder assembly 12. Figure 5 shows an example of what happens when the fuse or relay 14 is not properly aligned with the receptacle 16 prior to insertion or when the receptacle 16 is slightly damaged prior to insertion, the details of which are now explained.

The device 10 includes a spring 36 that urges the pin 34 toward the set position 38 with a retaining force 40. The retention force 40 is selected to be greater than the insertion force 42 required to press the fuse or relay 14 into the receptacle 16 when the fuse or relay 14 is aligned with the receptacle 16 and the receptacle 16 is not otherwise deformed or damaged (Fig. 3). . That is, the retention force 40 is expected to be sufficient to overcome the insertion force 42 that fully inserts the fuse or relay 14 into the receptacle 16.

The device 10 also includes a switch 44 that detects when the pin 34 is forced away from the set position 38 thereby indicating that the fuse or relay 14 is not aligned with the receptacle 16 or that the receptacle 16 is otherwise deformed or damaged. Accordingly, the spring 36 is advantageously selected to move the press pin 34 away from the set position 38 prior to causing irreparable damage or further damage to the receptacle 16. In this non-limiting example, the pin 34 is in contact with the switch 44, thereby indicating that the force required to insert the fuse or relay 14 into the receptacle appears to be excessive. The switch 44 can be a light that can be seen as an indicator by the operator of the device 10 indicating that the operation as the handle should be reversed and the cause of excessive insertion force should be investigated. Alternatively, if the handle 18 is replaced by a certain type of actuator, the signal from the switch 44 can be used to stop and/or reverse the operation of the actuator.

Accordingly, a fuse and relay insertion height control device (device 10) is provided. The apparatus 10 provides a means for inserting a fuse or relay into the fuse holder assembly 12 with consistent results and detecting when the insertion of one or more of those fuses or relays is not as expected We do that. The cooperation of the spring 36 with the switch 44 provides the ability to detect the presence of a fuse or relay 14 insertion prior to irreparable damage to the fuse holder assembly 12. s method.

While the invention has been described in terms of its preferred embodiments, it is not intended to
