Description

Technical Field

[0001] The utility model relates to an electrical measuring device for a wire harness, which is applicable to the technical field of wire harness measurement. Background Art

[0002] Wiring harness testing involves testing the wiring connections between devices in a circuit to detect short circuits, open circuits, and other faults in the wires within the harness. Conventional testing of wiring harnesses is typically performed using an electrical tester and a test pencil. The tester first connects one end of the harness to the tester. Then, holding the other end of the harness with one hand, the tester separates the wire ends. With the other hand, the test pencil is held, and the test tip of the test pencil touches the wire ends one by one to complete the wiring harness testing. However, the above test method has complicated operation steps. It is necessary to connect the wiring harness first and then use a tester to test the wire ends, which has low test efficiency. In addition, the tip of the tester and the wire ends are both small in size. When the tester holds the tester and the wiring harness for point testing respectively, it is easy for the tester tip to lose effective contact with the wire ends due to hand shaking or lack of concentration. This not only affects the test efficiency, but also makes the tester more prone to fatigue, posing certain safety hazards. In addition, the wires in some wiring harness products need to be tested in a certain order. The existing test method is prone to false touches, affecting the accuracy of the test results. Utility Model Content

[0003] In order to solve the defects of the above-mentioned prior art, the utility model proposes an electrical measuring device for a wiring harness.

[0004] The technical solution adopted by the utility model is an electrical measuring device for a wiring harness, comprising an electrical measuring device for measuring the continuity of the wiring harness, at least one test fixture connected to the electrical measuring device, each test fixture comprising a first plug connector for connecting to one end of the wiring harness to be measured, a second plug connector detachably connected to the first plug connector, a first connecting wire the same number as the number of wires in the wiring harness to be measured and having two ends respectively connected to the first port and the second plug connector of the electrical measuring device, a detection board for contacting the wire end at the other end of the wiring harness to be measured, and a second connecting wire connected to the second port of the electrical measuring device and the detection board at two ends respectively, wherein the detection board is set to be a conductive material. By using the electrical measuring device and the test fixture, when testing the wiring harness, the tester can hold the first connector at one end of the wiring harness under test and the wire at the other end with both hands respectively. Then, one hand can connect the first connector to the second connector, and the other hand can contact the wire ends in the wiring harness under test with the test board in turn to test the wiring harness. This is not only convenient to operate and has high testing efficiency, but also saves the tester from having to maintain high concentration for a long time, reduces fatigue, and avoids safety hazards. It also avoids accidental touch when testing wires in a certain order, ensuring the accuracy of the test results.

[0005] Furthermore, the test fixture also includes a fixture base for fixing to the work surface, and the second plug connector and the detection board are fixedly arranged on the fixture base. The second plug connector and the detection board are fixed to the work surface through the fixture base, so that the test personnel can quickly and accurately plug and detect the wiring harness.

[0006] Furthermore, the second plug connector and the test board are both arranged at the front of the fixture base. Specifically, the fixture base is arranged at the edge of the work surface, which is convenient for the tester to plug the first plug connector into the second plug connector, and also convenient for the wire end to contact the test board, avoiding interference between the hands and the fixture base and the work surface, which affects the tester's operation.

[0007] Furthermore, the second plug connector includes a first fixing portion and a number of plug holes defined in the first fixing portion, the number of which is the same as the number of the first connecting wires. The inner wall of the plug holes is made of conductive material, and the ends of the first connecting wires are inserted into the plug holes in a one-to-one correspondence. By inserting the ends of the first connecting wires into the plug holes with the conductive material inside, the first connecting wires are electrically connected to the wires in the wiring harness, facilitating testing of the wiring harness.

[0008] Furthermore, the first plug connector includes a second fixing portion, and plug terminals disposed in the second fixing portion, the number and position of which correspond to the plug holes. One end of the plug terminals is releasably plugged into the other end of the plug holes in a one-to-one correspondence, and the other end of the plug terminals is connected to the wires in the wiring harness under test in a one-to-one correspondence. The plug terminals and the plug holes enable releasable plugging between the first and second plug connectors. At the same time, the plug terminals enable electrical connection between the wires in the wiring harness and the first connecting wire when the first and second plug connectors are plugged together, thereby achieving connection between the wiring harness and the electrical measuring device.

[0009] Furthermore, a clamping block is provided on the second fixing portion, and an elastic hook is provided on the first fixing portion which is detachably engaged with the clamping block. When the first plug connector and the second plug connector are plugged in, the elastic hook is engaged with the clamping block, and the plug-in state of the first plug connector and the second plug connector is limited by the clamping block and the elastic hook, thereby ensuring the connection stability between one end of the wiring harness under test and the electrical measuring device, preventing the connection between one end of the wiring harness and the electrical measuring device from being disconnected during the test, and avoiding affecting the test process.

[0010] Due to the application of the above technical solution, the present invention has the following advantages over the prior art:

[0011] The electrical measuring device for a wiring harness in the present invention enables a tester to hold a first plug connector at one end of the wiring harness to be tested and a wire at the other end with both hands through the electrical measuring device and the test fixture, and then plug the first plug connector into the second plug connector with one hand, and use the other hand to sequentially contact the wire ends of the wire in the wiring harness to be tested with the test board to implement testing of the wiring harness. This not only facilitates operation and has high testing efficiency, but also saves the tester from having to maintain high concentration for a long time, reduces fatigue, and avoids potential safety hazards. It also avoids accidental touch when testing wires in a certain order, thereby ensuring the accuracy of the test results. BRIEF DESCRIPTION OF THE DRAWINGS

The detection plate 24 is made of a conductive material. By using the electrical testing device 1 and the test fixture 2, when testing the wiring harness, the tester can hold the first plug connector 21 at one end of the wiring harness to be tested and the wire at the other end with both hands respectively, and then use one hand to plug the first plug connector 21 into the second plug connector 22, and use the other hand to contact the wire ends in the wiring harness to be tested with the test board 24 in turn to test the wiring harness. This is not only convenient to operate and has high testing efficiency, but also saves the tester from having to maintain high concentration for a long time, reduces fatigue, and avoids safety hazards; it also avoids accidental touch when testing wires in a certain order, ensuring the accuracy of the test results.

[0022] In a more preferred embodiment, the test fixture 2 also includes a fixture base 26 for fixing to the work surface, and the second plug connector 22 and the detection board 24 are fixedly set on the fixture base 26.
