Each slide block has a U-shaped structure, and a clamping plate is slidably connected inside the slide block. A fixing bolt is inserted into one side of the open end of each slide block, and the end of the fixing bolt is rotatably connected to the clamping plate. A groove is formed inside the other side of the open end of the slide block, and an electric push rod is fixedly connected inside the groove.

[0006] Preferably, the telescopic component includes a sleeve and a telescopic plate. One end of the telescopic plate is slidably installed inside the sleeve. The surface of the telescopic plate has equidistantly distributed positioning holes. Positioning bolts are inserted into the surface of the sleeve. One end of each positioning bolt is inserted into a corresponding positioning hole. The sleeve and the telescopic plate are respectively fixedly connected to two sets of sliding blocks.

[0007] Preferably, a handle is fixedly connected to the outer surface of the sleeve.

[0008] Preferably, the test piece includes a test needle, which is fixedly connected to an electric push rod. One end of the test needle is connected to a wire, and one end of the wire is located outside the slide block. The wire slides in cooperation with the slide block, and the end of the wire located outside the slide block is fixedly connected to a connector.

[0009] Preferably, the side of the clamping plate opposite to the inner surface of the slide is set to be arc-shaped.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] This invention, by incorporating a telescopic component, allows for adjustment of the detection length of the wire harness as needed. After adjustment, the two ends of the wire harness to be tested are placed inside the slide block, and two sets of fixing bolts are tightened in sequence to fix the wire harness against the clamp plate. Then, by driving the electric push rod to extend, two sets of test probes pierce the insulation layer of the wire harness and contact the cable inside the wire harness. Finally, the two sets of connectors are connected to the positive and negative terminals of the external detection device, thereby realizing the detection of the wire harness.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a battery module wiring harness sequence testing device, including a telescopic component. Both the fixed end and the telescopic end of the telescopic component are fixedly connected to a slide block 6. The slide block 6 is configured as a U-shaped structure. A clamping plate 7 is slidably connected inside the slide block 6. A fixing bolt 8 is inserted into one side of the open end of the slide block 6. The end of the fixing bolt 8 is rotatably connected to the clamping plate 7. A sliding groove 12 is opened inside the other side of the open end of the slide block 6. An electric push rod 13 is fixedly connected inside the sliding groove 12. A test piece is fixedly connected to the telescopic end of the electric push rod 13. The electric push rod 13 can drive one end of the test piece to move into or out of the sliding groove 12.

[0018] Furthermore, the test piece includes a test needle 11, which is fixedly connected to an electric push rod 13. One end of the test needle 11 is wired to a wire 3, one end of which is located outside the slide block 6 and slides with the slide block 6. The end of the wire 3 located outside the slide block 6 is fixedly connected to a connector 5.

[0019] Furthermore, the sides of the inner surfaces of the clamping plate 7 and the slide 6 that are opposite each other are both set to be arc-shaped.

[0020] In this embodiment, by setting a telescopic component, the detection length of the wire harness can be adjusted as needed. After adjustment, the two ends of the wire harness to be tested are placed inside the slide block 6, and the two sets of fixing bolts 8 are tightened in sequence to make the clamp 7 abut against the wire harness and fix the wire harness. Then, by driving the electric push rod 13 to extend, the two sets of test needles 11 are driven to pierce the insulation layer of the wire harness and contact the cable inside the wire harness. Finally, the two sets of connectors 5 are connected to the positive and negative poles of the external detection device, thereby realizing the detection of the wire harness.

[0021] After the test is completed, the test probe 11 is moved out of the wire harness by the electric push rod 13. The holes in the wire harness insulation layer can be filled with insulating glue, and insulating tape is wrapped around the holes on the wire harness surface. Therefore, the wire harness can be reused and waste is avoided.

[0022] It should be noted that external testing devices can apply high voltage or current to the wire harness to test its withstand voltage capability. The relevant testing structure and principle are existing conventional technologies and will not be elaborated here.

[0023] Furthermore, the telescopic component includes a sleeve 1 and a telescopic plate 2. One end of the telescopic plate 2 is slidably installed inside the sleeve 1. The surface of the telescopic plate 2 is provided with equidistantly distributed positioning holes 9. Positioning bolts 10 are inserted into the surface of the sleeve 1. One end of the positioning bolts 10 is inserted into the corresponding positioning holes 9. The sleeve 1 and the telescopic plate 2 are respectively fixedly connected to two sets of sliding blocks 6.

[0024] Furthermore, a handle 4 is fixedly connected to the outer surface of the sleeve 1.

[0025] In this embodiment, when it is necessary to adjust the length of the telescopic component, first unscrew the positioning bolt 10 from the positioning hole 9, then pull out the telescopic plate 2, adjust the overall length of the sleeve 1 and the telescopic plate 2, and after adjusting to the target length, screw the positioning bolt 10 into the corresponding positioning hole 9.
