Detailed Implementation
[0026] The following description of the embodiments is with reference to the accompanying illustrations, which illustrate specific embodiments in which the present invention can be implemented.
[0027] This utility model provides a quick-connect terminal block, the structure of which is as follows: Figures 2-3As shown, the device includes a terminal block 1 with several wiring channels 10 and several wiring mechanisms 2 corresponding to each wiring channel 10. Each wiring mechanism 2 includes a conductive busbar 21, a pressure block 22, and an elastic element 23. The conductive busbar 21 is fixedly disposed in the corresponding wiring channel 10 and is electrically connected to an external EOL device. The pressure block 22 is disposed opposite to the conductive busbar 21. At least one end face of the pressure block 22 and the conductive busbar 21 is an inclined surface, so that a V-shaped connection port 20 is formed between the end of the pressure block 22 and the end of the conductive busbar 21. Preferably, the end faces of both the pressure block 22 and the conductive busbar 21 are inclined surfaces to form a V-shaped connection port 20 with an acute angle. One end of the elastic element 23 is fixedly connected to the inner wall of the wiring channel 10, and the other end is fixedly connected to the pressure block 22.
[0028] Since at least one of the pressure block 22 and the conductive busbar 21 has an inclined end face, a V-shaped connection port 20 is formed between the end of the pressure block 22 and the end of the conductive busbar 21. Therefore, during online testing, the high-voltage harness terminal 100 to be tested can be directly inserted through the V-shaped connection port 20. The pressure block 22, under the elastic force of the elastic member 23, can press the high-voltage harness terminal 100 to be tested firmly against the surface of the conductive busbar 21. Figure 5 The diagram shows the working state of the quick-connect terminal block provided by this utility model. In this way, the high-voltage harness terminal 100 to be tested is electrically connected to the external EOL equipment through the conductive busbar 21. When disconnecting, the high-voltage harness terminal 100 can be directly unplugged, making the connection and disconnection of the high-voltage harness terminal 100 very convenient and saving testing time.
[0029] As a specific embodiment, since the high-voltage harness terminals 100 at both ends of the high-voltage harness need to be connected simultaneously when performing EOL testing on the high-voltage harness, the terminal block 1 in this embodiment has two wiring channels 10, and each wiring channel 10 is provided with the wiring mechanism 2. Preferably, the two wiring channels 10 of the terminal block 1 are arranged side by side.
[0030] Specifically, the terminal block 1 includes a base 11 and a top cover 12 arranged from bottom to top, such as... Figure 4 The diagram shown is a structural schematic of the quick-connect terminal block after the top cover is removed in an embodiment of the present invention. The upper surface of the base 11 is provided with a plurality of grooves 110. The top cover 12 is detachably fixed on the top of the base 11 to cooperate with the grooves 110 to form a plurality of wiring channels 10.
[0031] In this embodiment, the conductive busbar 21, the pressure block 22, and the elastic element 23 are arranged sequentially from bottom to top in the corresponding wiring channel 10, and the conductive busbar 21 is fixedly disposed at the bottom of the groove 110, and the end of the elastic element 23 away from the pressure block 22 is fixedly connected to the upper cover 12; preferably, the conductive busbar 21 is a conductive copper busbar, and the elastic element 23 is a spring.
[0032] Furthermore, in order to fix the conductive bus 21 to the bottom of the groove 110, the wiring mechanism 2 also includes a fastener 24, and the conductive bus 21 is detachably fixed to the bottom of the groove 110 by the fastener 24; preferably, the fastener 24 is a screw.
[0033] Furthermore, the pressure block 22 has a guide hole 220 at the position corresponding to the fastener 24, the shape of which matches the cross-sectional shape of the top of the fastener 24. The top of the fastener 24 protrudes from the upper surface of the conductive busbar 21 and extends at least into the guide hole 220. The fastener 24 and the guide hole 220 are coaxially arranged and are both parallel to the elastic member 23.
[0034] It is understood that, since the top end of the fastener 24 protrudes from the upper surface of the conductive busbar 21 and extends at least into the guide hole 220, when the pressure block 22 moves closer to or further away from the conductive busbar 21, the top end of the fastener 24 can engage with the guide hole 220 to guide the moving pressure block 22 and prevent the pressure block 22 from wobbling left and right due to friction when the high-voltage wire harness terminal 100 is inserted or pulled out.
[0035] Furthermore, the upper cover 12 has a downwardly protruding protrusion 120 on one end face near the V-shaped connection port 20, which is used to cooperate with the end of the pressure block 22 to limit the pressure block 22.
[0036] It is easy to understand that the protrusion 120 can cooperate with the end of the pressure block 22 to limit the pressure block 22, so as to prevent the pressure block 22 from moving laterally (to the left) when the high voltage harness terminal 100 is pulled out.
[0037] Please continue to refer to Figure 3 and Figure 4In this embodiment of the present invention, the wiring mechanism 2 further includes a terminal block 25 electrically connected to an external EOL device. The terminal block 25 is fixedly disposed within the wiring channel 10 and electrically connected to the corresponding conductive busbar 21. Specifically, the terminal block 25 and the conductive busbar 21 are fixedly disposed from bottom to top within the wiring channel 10. The fastener 24 passes through the conductive busbar 21 and the terminal block 25 in sequence to fix them within the wiring channel 10, and the end of the terminal block 25 is in electrical contact with the end of the conductive busbar 21.
[0038] It is easy to understand that by fixing the terminal 25 (which is electrically connected to the external EOL device) in the wiring channel 10 and electrically connecting it to the conductive busbar 21, the quick-connect terminal in this embodiment is configured to always be electrically connected to the external EOL device, so that only the high-voltage harness terminal 100 to be tested needs to be connected when performing EOL testing.
[0039] To facilitate understanding of this solution, the following is combined with... Figures 1-5 The working principle of this utility model will be described in detail below:
[0040] During operation, the high-voltage harness terminals 100 at both ends of the high-voltage harness to be tested are inserted into the V-shaped connectors 20 of the two wiring mechanisms 2. Upon insertion, the high-voltage harness terminals 100 push open the pressure blocks 22, causing the pressure blocks 22 to gradually move away from the conductive busbar 21 until the distance between the pressure blocks 22 and the conductive busbar 21 equals the thickness of the high-voltage harness terminal 100. After the high-voltage harness terminals 100 at both ends of the high-voltage harness are connected to the two wiring mechanisms 2, the external EOL device is activated to begin EOL testing of the high-voltage harness. After the test is completed, the high-voltage harness terminals 100 at both ends of the high-voltage harness are simply pulled out from the V-shaped connectors 20.
[0041] In summary, in the quick-connect terminal block provided by this utility model, since at least one of the end faces of the pressure block 22 and the conductive bar 21 is an inclined surface, a V-shaped connection port 20 is formed between the end of the pressure block 22 and the end of the conductive bar 21. Thus, during online testing, the high-voltage harness terminal 100 to be tested can be directly inserted from the V-shaped connection port 20; during offline testing, the high-voltage harness terminal 100 can be directly pulled out. This makes the connection of the high-voltage harness terminal 100 during online testing and the disassembly during offline testing very convenient, saving testing time.
[0042] It should be noted that although the present invention has been disclosed above with specific embodiments, the above embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
