Description

[0001] This application is a divisional application. The application date of the original application is December 29, 2023. The application number is: 202323636003.8. The name of the invention is: Connector clamping device and automobile wiring harness assembly and testing device. Technical Field

[0002] The utility model relates to the technical field of automobile wiring harness manufacturing equipment, in particular to a connector clamping device and an automobile wiring harness assembly and testing device. Background Art

[0003] A wiring harness is a component that combines multiple wires into a circuit by crimping copper contacts (connectors) with wires and cables, then applying a plastic-molded insulator or metal casing. In automotive electrical systems, the wiring harness is the network backbone, connecting the vehicle's electrical and electronic components and enabling their functionality. Without the wiring harness, there would be no circuit.

[0004] With the increasing demand for automotive functions and the widespread application of electronic control technology, the number of electrical components has increased significantly, and the number of circuits and power consumption in cars has increased significantly. The number of wires in the wiring harness has also increased, and the wiring harness has become thicker and heavier, resulting in higher production costs and a corresponding increase in failure rates. This has necessitated a sophisticated wiring harness assembly process to ensure product quality and reduce production costs. Therefore, how to more effectively and reasonably arrange a large number of wiring harnesses within the limited space of a car, so that the wiring harness can play a greater role, has become a challenge facing the automotive industry.

[0005] Currently, wiring harness manufacturers have put forward increasingly higher requirements for the production quality of automotive wiring harnesses. However, with the large variety of raw materials and the complexity of automotive wiring harnesses, manufacturers do not have a better operation method. Most of them can only control each process once in the traditional way, which leads to low production efficiency. Therefore, it is necessary to design a multifunctional operating device that can combine multiple processes of automotive wiring harnesses as much as possible, so that the same operator can complete multiple processes on the same device to improve production efficiency. Utility Model Content

[0006] The purpose of the utility model is a connector clamping device and an automobile wiring harness assembly and testing device, which combines automobile wiring harness detection and bundling processes and implements them on one operating device. It can not only detect the length of each wire in the wiring harness, but also improve the production quality and production efficiency of automobile wiring harnesses. It has strong versatility and the components on the adjustment device can be suitable for the production of different products.

[0007] In order to achieve the above technical purpose, the technical solution of the utility model is:

[0008] An automotive wiring harness assembly and testing device includes multiple groups (not less than one group) of wire end positioning blocks and multiple (not less than one) tie band positioning blocks, wherein the wire end positioning blocks include a first wire end positioning block and a second wire end positioning block, and the tie band positioning blocks are provided with a wire positioning groove and a tie band bundling groove, wherein the wire positioning groove is used to position the wire, and the tie band bundling groove is used to bundle the wire with a tie, and the wire end positioning blocks and the tie band positioning blocks are arranged according to the wiring harness structure, and the first wire end positioning block and the second wire end positioning block of each group of wire end positioning blocks are respectively used to position the two ends of a certain wire, and the length of a certain wire is detected through the path from the first wire end positioning block to the tie band positioning block to the second wire end positioning block.

[0009] The number and layout of the first wire end positioning block, the second wire end positioning block, and the tie band positioning block on the base plate are distributed according to the wiring harness structure, the wire bundling point, and the wire length. The ends of the wires are then connected to the first wire end positioning block and the second wire end positioning block in sequence, and the wires are inserted into the wire positioning slots of the tie band positioning blocks. When a wire in the wiring harness is too long or too short, it can be quickly detected. For example, if a wire in the wiring harness is too short, when the wire is inserted into the wire positioning slot and one end is connected to the first wire end positioning block, the other end of the wire cannot connect to the corresponding second wire end positioning block. For another example, if a wire in the wiring harness is too long, when the wire is inserted into the wire positioning slot and one end is connected to the first wire end positioning block, the other end of the wire will exceed the position of the corresponding second wire end positioning block, thereby realizing rapid detection of the wire length to detect whether the length of each wire in the wiring harness meets the size requirements. No length measurement is required during the full inspection in the subsequent process, thus reducing the production process and improving product quality and production efficiency.

[0010] When the harness wires are connected to the tie-strap positioning block, the wire positioning grooves on the tie-strap positioning block position and guide the wires. The tie-strap binding grooves on the tie-strap positioning block not only locate the binding point for the wires but also allow the tie-strap to pass between the wires and the tie-strap positioning block to achieve wire bundling. This ensures that each wire harness is tied in the same position, ensuring that the harness meets standard requirements and improving product quality. For example, the tie-strap is inserted between the wires and the tie-strap positioning block through one side of the tie-strap binding groove and exits from the other side of the tie-strap binding groove, achieving fixed wire bundling and improving product quality and bundling efficiency.

[0011] It should be noted that if a certain set of wire end locating blocks is used to locate and detect the length of a certain wire in a wiring harness, the number of wire end locating blocks should be set in a 1:1 matching manner according to the number of wires in the wiring harness. If the first wire end locating block and the second wire end locating block are used to locate the two ends of a certain wire in the wiring harness, the number of the first wire end locating blocks and the number of the second wire end locating blocks should also be set in a 1:1 matching manner according to the number of wires in the wiring harness (the sum of the number of the first wire end locating blocks and the second wire end locating blocks is twice the number of wires in the wiring harness). However, the multiple groups in the above multiple sets of wire end locating blocks are functional descriptions and do not represent the physical number of wire end locating blocks. In actual use, the same wire end locating block can simultaneously locate the ends of multiple wires to achieve the function of detecting the length of the wires in the wiring harness. For example, the end locating functions of multiple wires can be combined on the same physical end locating block to achieve the function of the same physical end locating block to simultaneously locate the ends of multiple wires. Similarly, the first wire end locating block and the second wire end locating block are only functional descriptions that reflect the distinction between the two ends of a certain wire to achieve the wire end locating function, and do not specifically refer to a physical end locating block. For example, the second wire end positioning block for positioning a certain wire may also be the first wire end positioning block for another wire.

[0012] The tie-strap positioning block is a three-hole tie-strap positioning block or a two-hole tie-strap positioning block. The three-hole tie-strap positioning block has a wire positioning slot with three wire inlets and outlets, while the two-hole tie-strap positioning block has a wire positioning slot with two wire inlets and outlets. The three-hole tie-strap positioning block is provided with two tie-strap bundling slots.

[0013] The wire end positioning blocks are all provided with test leads, which are used to connect the wires. By measuring the test leads at both ends of the same wire in the wiring harness, it is possible to detect whether the wires are conductive and whether the contact resistance of the wires is within the standard range.

[0014] The physical structures of the first wire end positioning block and the second wire end positioning block can be configured with wire end positioning blocks of different structures according to the conditions of the wire ends.

[0015] For example, the wire end positioning block may be provided with a connector clamping device, which is used to clamp the connector at the wire end. The connector clamping device can be used to quickly clamp the connector, thereby reducing operation difficulty and improving work efficiency.

[0016] The connector clamping device is provided with a plug-in, which is used to plug the connector at the end of the wire. The copper terminal of the plug-in is connected to the copper terminal of the connector, and the copper terminal of the plug-in is connected to the test lead.

[0017] The connector clamping device includes a connector tail end stop block, and the connector tail end stop block is cooperated with a stop block avoidance slide groove. The connector tail end stop block slides back and forth along the stop block avoidance slide groove. A reset spring is provided between the connector tail end stop block and the stop block avoidance slide groove. After the connector tail end stop block slides and avoids along the stop block avoidance slide groove, the reset spring is used to reset the connector tail end stop block to the tail end of the connector.

[0018] The connector tail end stop block is provided with an extrusion inclined surface, and the extrusion inclined surface is used to push the connector tail end stop block to slide along the stop block avoidance groove.

[0019] In order to guide the sliding direction of the connector tail end stop block and limit the connector tail end stop block to prevent the connector tail end stop block from escaping from the stop block avoidance groove, the connector tail end stop block is provided with a guide rod, and the stop block avoidance groove is provided with a guide bar hole. When the connector tail end stop block slides along the stop block avoidance groove, the guide rod slides in the guide bar hole.

[0020] When in use, the connector at the end of the wire is inserted into the plug-in unit parallel to the side of the connector tail end stop block. During this process, the connector at the end of the wire pushes the extrusion bevel of the connector tail end stop block, causing the connector tail end stop block to slide along the stop block avoidance groove (the guide rod slides in the guide bar hole); after the extrusion bevel is freed from the restraint of the connector, the reset spring is reset, causing the connector tail end stop block to slide and reset along the stop block avoidance groove, thereby causing the connector tail end stop block to be blocked at the tail end of the connector.

[0021] The copper terminals of the plug-in connectors are provided with arc-shaped protrusions. During use, these arc-shaped protrusions increase the contact area between the plug-in copper terminals and the connector copper terminals, ensuring close contact between the plug-in terminals and the connector terminals. The arc-shaped transition also makes insertion and removal easier, reducing worker fatigue.

[0022] The wire end positioning block may be provided with a terminal detection groove, in which a terminal connecting column is provided. The terminal connecting column is used to detect the inner diameter of the O-type terminal at the wire end, and the terminal detection groove is used to detect the outer diameter of the O-type terminal at the wire end.

[0023] Terminal detection slots and terminal connection posts of the same size are set up according to the model and size of the wire harness O-type terminal. When in use, the terminal detection slot can detect the outer diameter of the wire O-type terminal, and the terminal connection post can detect the inner diameter of the wire O-type terminal. If the inner diameter of the O-type terminal is too large, there will be a gap between it and the terminal connection post after it is placed in the terminal detection slot; if the inner diameter of the O-type terminal is too small, it cannot be installed on the terminal connection post; if the outer diameter of the O-type terminal is too large, it cannot be placed in the terminal detection slot; if the outer diameter of the O-type terminal is too small, there will be a gap between it and the terminal detection slot after it is installed on the terminal connection post; therefore, the terminal detection slot and terminal connection post can quickly detect the size of the O-type terminal to ensure product quality. At the same time, the setting of the terminal detection slot and terminal connection post has a fool-proof effect and is easy for operators to operate.

[0024] The terminal connection column is connected to a test lead.

[0025] Beneficial effects of the utility model:

[0026] 1. This utility model can simultaneously realize multiple functions such as automobile wiring harness assembly, size detection, harness binding, conductivity test, insulation resistance test, contact resistance test, etc.

[0027] 2. Each function of the device of the utility model can play a fool-proof effect, which can improve production efficiency and product quality.

[0028] 3. The various components and layouts of the present invention can be customized according to the wiring harness structure, thereby increasing the adaptability of the device and reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 1-2 As shown, the automotive wiring harness includes a first wire 11, a second wire 12 and a third wire 13. The head end and tail end of the first wire 11, the head end of the second wire 12, and the head end of the third wire 13 are all connected to a connector 10 (the connector 10 and the plug-in 7 are both a spliceable electrical connector disclosed in the authorization announcement number CN202487866U. The two spliceable electrical connectors are docked and buckled together to achieve the electrical connection of the line). The tail end of the second wire 12 and the tail end of the third wire 13 are both connected to the O-type terminal 14. The connector 10 at the head end of the first wire 11 and the connector at the head end of the second wire 12 are connected. 10 are arranged adjacent to each other, the connector 10 at the tail end of the first wire 11 and the connector 10 at the head end of the third wire 13 are arranged adjacent to each other, the first wire 11, the second wire 12 and the third wire 13 are arranged in a T-shaped structure, at the intersection of the second wire 12, the third wire 13 and the first wire 11 (the intersection of 11, 12, 13), the second wire 12 and the first wire 11 are bundled with a first strap 15a, the third wire 13 and the first wire 11 are bundled with a second strap 15b, and between the intersection and the tail end of the second wire 12 and the tail end of the third wire 13, the second wire 12 and the third wire 13 are bundled with a third strap 15c.

[0038] like Figure 1-7 As shown, according to the wiring harness structure, wire bundling point, and wire length of the above-mentioned automobile wiring harness, an automobile wiring harness assembly and testing device includes a base plate 1, on which a left first wire end positioning block 41, a right first wire end positioning block 42, a left second wire end positioning block 81, and a right second wire end positioning block 82 are connected by screws. The left first wire end positioning block 41 is used to position the head end of the first wire 11 and the head end of the second wire 12, the right first wire end positioning block 42 is used to position the tail end of the first wire 11 and the head end of the third wire 13, the left second wire end positioning block 81 is used to position the tail end of the second wire 12, and the right second wire end positioning block 82 is used to position the tail end of the third wire 13.

[0039] Between the left first wire end positioning block 41 and the right first wire end positioning block 42, a three-hole tie band positioning block 2 is connected to the base plate 1 by screws, and the three-hole tie band positioning block 2 is provided with a wire positioning groove. The three-hole tie band positioning block 2 is located at the above-mentioned intersection (the intersection of 11, 12, and 13), and the first wire 11, the second wire 12, and the third wire 13 are all inserted into the wire positioning groove of the three-hole tie band positioning block 2. Specifically, the wire positioning groove of the three-hole tie band positioning block 2 is provided with a first three-hole wire inlet and outlet 21 and a second three-hole wire inlet and outlet 22. Between the first three-hole wire inlet and outlet 21 and the second three-hole wire inlet and outlet 22, the wire positioning groove of the three-hole tie band positioning block 2 is also provided with a third three-hole wire inlet and outlet 23. The first three-hole wire inlet and outlet 21, the second three-hole wire inlet and outlet 22 and the third three-hole wire inlet and outlet 23 are all connected to the wire positioning groove of the three-hole tie band positioning block 2 and are distributed in a T shape. The first three-hole wire inlet and outlet 21 is used to position the first wire 11 and the second wire 12, the second three-hole wire inlet and outlet 22 is used to position the first wire 11 and the third wire 13, and the third three-hole wire inlet and outlet 23 is used to position the second wire 12 and the third wire 13.

[0040] A gap is left between the left second wire end positioning block 81 and the right second wire end positioning block 82 on the base plate 1 according to the above-mentioned wiring harness structure. Between the three-hole harness positioning block 2 and the left second wire end positioning block 81 and the right second wire end positioning block 82, a two-hole harness positioning block 3 is connected to the base plate 1 by screws. The two-hole harness positioning block 3 is provided with a wire positioning groove. The wire positioning groove of the two-hole harness positioning block 3 is provided with a first two-hole wire inlet and outlet 31 and a second two-hole wire inlet and outlet 32. The first two-hole wire inlet and outlet 31 and the second two-hole wire inlet and outlet 32 ​​are both connected to the wire positioning groove of the two-hole harness positioning block 3, and the second wire 12 and the third wire 13 are inserted into the wire positioning groove of the two-hole harness positioning block 3.

[0041] The spacing between the left first wire end positioning block 41, via the three-hole tie-strap positioning block 2, and the right first wire end positioning block 42 is set according to the length of the first wire 11. The spacing between the left first wire end positioning block 41, via the three-hole tie-strap positioning block 2 and the two-hole tie-strap positioning block 3, and the left second wire end positioning block 81 is set according to the length of the second wire 12. The spacing between the right first wire end positioning block 42, via the three-hole tie-strap positioning block 2 and the two-hole tie-strap positioning block 3, and the right second wire end positioning block 82 is set according to the length of the third wire 13. Each wire end positioning block 41, 42, 81, 82 and each tie-strap positioning block 2, 3 are fixed to the base plate 1 at a specified position and spacing by screws. This allows the length of each wire 11, 12, 13 of the wiring harness to be quickly detected when the wires 11, 12, 13 are connected to each wire end positioning block and each tie-strap positioning block 2, 3, respectively. This facilitates operators in quickly determining whether the length of each wire in the wiring harness meets the standard during assembly and testing of the wiring harness.

[0042] For example, after the connector 10 at the head end of the first wire 11 and the connector 10 at the head end of the second wire 12 are positioned by the left first wire end positioning block 41, the first wire 11 passes through the three-hole tie band positioning block 2 to the right first wire end positioning block 42. If the first wire 11 meets the length standard, the connector 10 at the tail end of the first wire 11 can be just positioned by the right first wire end positioning block 42; if the first wire 11 is shorter, the connector 10 at the tail end of the first wire 11 cannot be positioned by the right first wire end positioning block 42; if the first wire 11 is longer, although the connector 10 at the tail end of the first wire 11 can be positioned by the right first wire end positioning block 42, the first wire 11 is in a non-tightened state. When it is in a tight state, the end of the first wire 11 will exceed the position of the right first wire end positioning block 42, thereby realizing the detection of the first wire 11. For example, after the connector 10 at the head end of the first wire 11 and the connector 10 at the head end of the second wire 12 are positioned by the left first wire end positioning block 41, the second wire 12 passes through the three-hole tie-band positioning block 2 and the two-hole tie-band positioning block 3 to the left second wire end positioning block 81. If the second wire 12 meets the length standard, the O-type terminal 14 at the tail end of the second wire 12 can be just positioned by the left second wire end positioning block 81; if the second wire 12 is shorter, the O-type terminal 14 at the tail end of the second wire 12 cannot be positioned by the left second wire end. The positioning block 81 is used for positioning; if the second wire 12 is long, although the O-type terminal 14 at the tail end of the second wire 12 can be positioned by the left second wire end positioning block 81, the second wire 12 is in a non-tightened state. When it is in a tight state, it will exceed the left second wire end positioning block 81, thereby realizing the detection of the second wire 12; the same principle is used to realize the detection of the third wire 13 through the right first wire end positioning block 42, the three-hole tie positioning block 2, the two-hole tie positioning block 3 and the left second wire end positioning block 82.

[0043] In order to position the adjacent connectors 10 at the head ends of the first wires 11 and the connectors 10 at the head ends of the second wires 12, as well as the adjacent connectors 10 at the tail ends of the first wires 11 and the connectors 10 at the head ends of the third wires 13, the left first wire end positioning block 41 and the right first wire end positioning block 42 are both provided with connector clamping devices. The connectors 10 at the head ends of the first wires 11 and the connectors 10 at the head ends of the second wires 12 are combined and clamped in the connector clamping device of the left first wire end positioning block 41, and the connectors 10 at the tail ends of the first wires 11 and the connectors 10 at the head ends of the third wires 13 are combined and clamped in the connector clamping device of the right first wire end positioning block 42. Here, the connector clamping device can realize the simultaneous clamping of two connectors 10, that is, the connector clamping device combines the positioning functions of the ends of two wires. For example, the connector clamping device of the right first wire end positioning block 42 combines the positioning functions of the tail end connector 3 of the first wire 11 and the head end connector 3 of the third wire 13. The right first wire end positioning block 42 is not only the tail end positioning block of the first wire 11, but also the head end positioning block of the third wire 13.

[0044] Specifically, the connector clamping device is provided with a plug-in 7 and a connector tail end stop block, and the connector tail end stop block includes a right connector tail end stop block 5 and a left connector tail end stop block 6, and the right connector tail end stop block 5 and the left connector tail end stop block 6 are symmetrically arranged.

[0045] The right connector tail end stop block 5 is cooperated with a right stop block avoidance groove 51, and a right return spring 52 is provided between the right connector tail end stop block 5 and the right stop block avoidance groove 51. The right connector tail end stop block 5 is provided with a right guide rod 53, and the right stop block avoidance groove 51 is provided with a right guide bar hole 54. When the right connector tail end stop block 5 slides back and forth along the right stop block avoidance groove 51, the right guide rod 53 slides along the right guide bar hole 54, and the right guide bar hole 54 guides and limits the right guide rod 53; after the right connector tail end stop block 5 slides and avoids along the right stop block avoidance groove 51, the right return spring 52 is used to reset the right connector tail end stop block 5 to the tail end of the connector.

[0046] The left connector tail end stop block 6 is cooperated with a left stop block avoidance groove 61, and a left return spring 62 is provided between the left connector tail end stop block 6 and the left stop block avoidance groove 61. The left connector tail end stop block 6 is provided with a left guide rod 63, and the left stop block avoidance groove 61 is provided with a left guide bar hole 64. When the left connector tail end stop block 6 slides back and forth along the left stop block avoidance groove 61, the left guide rod 63 slides along the left guide bar hole 64, and the left guide bar hole 64 guides and limits the left guide rod 63; after the left connector tail end stop block 6 slides and avoids along the left stop block avoidance groove 61, the left return spring 62 is used to reset the left connector tail end stop block 6 to the tail end of the connector.

[0047] On the front side of the left connector tail end stop block 6 and the right connector tail end stop block 5, the left connector tail end stop block 6 and the right connector tail end stop block 5 are both provided with extrusion slopes, and the plug-in 7 is provided on the rear side of the left connector tail end stop block 6 and the right connector tail end stop block 5, and the plug-in 7 is provided with two connector 10 sockets, which can realize the simultaneous plug-in of two connectors 10.

[0048] When in use, taking the left first wire end positioning block 41 as an example, the connector 10 at the head end of the first wire 11 and the connector 10 at the head end of the second wire 12 are inserted into the plug-in unit 7 side by side and in parallel from the front side of the connector tail end stop block. During the insertion process, the connectors 10 at the head ends of the first wire 11 and the second wire 12 push the extrusion inclined surface of the right connector tail end stop block 5 and the extrusion inclined surface of the left connector tail end stop block 6 respectively, and the right connector tail end stop block 5 and the left connector tail end stop block 6 are subjected to force to slide along the stop block avoidance slot to avoid (the guide rod slides along the guide bar hole); after the connector tail end stop block is freed from the connector constraint, the right return spring 52 is reset, so that the right connector tail end stop block 5 slides and resets along the right stop block avoidance slot 51, so that the right connector tail end stop block 5 is blocked at the tail end of the connector, and the left return spring 62 is reset, so that the left connector tail end stop block 6 slides and resets along the left stop block avoidance slot 61, so that the left connector tail end stop block 6 is blocked at the tail end of the connector. Similarly, the right first wire end positioning block 42 is used to position the connector 10 at the tail end of the first wire 11 and the connector 10 at the head end of the third wire 13 .

[0049] In order to locate and detect the O-type terminals 14 at the tail end of the second wire 12 and the tail end of the third wire 13, the left second wire end positioning block 81 and the right second wire end positioning block 82 are both provided with terminal connection grooves 91, and terminal connection columns 9 are both provided in the terminal connection grooves 91. The terminal connection columns 9 are used to detect the inner diameter of the wire O-type terminals, and the terminal detection grooves 91 are used to detect the outer diameter of the O-type terminals.

[0050] Specifically, taking the left second wire end positioning block 81 as an example, the sizes of the terminal connection groove 91 and the terminal connection column 9 of the left second wire end positioning block 81 are set according to the same inner diameter and outer diameter of the O-type terminal 14 of the second wire 12. During use, if the inner diameter of the O-type terminal 14 of the second wire 12 is too large, after it is placed in the terminal detection groove 91 of the left second wire end positioning block 81, there will be a gap between the O-type terminal 14 of the second wire 12 and the terminal connecting column 9 of the left second wire end positioning block 81; if the inner diameter of the O-type terminal is too small, it cannot be mounted on the terminal connecting column 9 of the left second wire end positioning block 81; if the outer diameter of the O-type terminal is too large, it cannot be placed in the terminal detection groove 91 of the left second wire end positioning block 81; if the outer diameter of the O-type terminal is too small, after it is mounted on the terminal connecting column 9 of the left second wire end positioning block 81, there will be a gap between it and the terminal detection groove 91 of the left second wire end positioning block 81; therefore, through the terminal connection groove 91 and the terminal connection column 9 of the left second wire end positioning block 81, the size of the O-type terminal at the tail end of the second wire 12 can be quickly detected to ensure product quality. Similarly, the terminal connection groove 91 and the terminal connection column 19 of the right second wire end positioning block 82 can also detect the inner diameter and outer diameter of the O-type terminal 14 of the third wire 13.

[0051] In order to realize the tests of wire conductivity, insulation resistance, contact resistance, etc., a copper terminal is provided in the jack of each connector of the plug-in, and the copper terminal of the plug-in is provided with a circular arc protrusion. The copper terminal of the plug-in is used to connect with the copper terminal of the connector. The circular arc protrusion can increase the contact area between the copper terminal of the plug-in and the copper terminal of the connector. The copper terminal of the plug-in and the terminal connecting column are respectively connected to the test lead. By connecting the test leads at both ends of each section of the wire, the test functions such as wire conductivity, insulation resistance, contact resistance, etc. are realized.

[0052] Specifically, the left first wire end positioning block 41 is provided with a first test lead 17a and a second test lead 16a, and the right first wire end positioning block 42 is provided with a third test lead 17b and a fourth test lead 16b. The first test lead 17a is connected to the copper terminal of the head end connector of the first wire 11 through the copper terminal of the plug-in, and the second test lead 16a is connected to the copper terminal of the head end connector of the second wire 12 through the copper terminal of the plug-in. The third test lead 17b is connected to the copper terminal of the tail end connector of the first wire 11 through the copper terminal of the plug-in, and the fourth test lead 16b is connected to the copper terminal of the head end connector of the third wire 13 through the copper terminal of the plug-in; the terminal connecting column 9 of the left second wire end positioning block 81 is connected to the fifth test lead 19a, and the fifth test lead 19a is used to connect the tail end of the second wire 12, and the terminal connecting column 9 of the right second wire end positioning block 82 is connected to the sixth test lead 19b, and the sixth test lead 19b is used to connect the tail end of the third wire 13. By measuring the test leads at both ends of the same wire in the wiring harness, it is possible to detect whether the wire is conductive and whether the contact resistance of the wire is within the standard range.
