Description

Technical Field

[0001] This utility model belongs to the field of wire harness testing technology, specifically a wire harness power-on testing fixing component. Background Technology

[0002] With the rapid development of electronic equipment and automobiles, wire harnesses are being used more and more widely in various electrical systems. Wire harness power-on testing is an important part of ensuring their safety and reliability.

[0003] Most existing wire harness fixing devices do not consider heat dissipation design. During the power-on testing process, especially when the current is large, the wire harness and testing equipment will generate a lot of heat. If this heat cannot be dissipated in time, it will cause the equipment to overheat, affecting the accuracy of the test and the service life of the equipment. To address this, we propose a wire harness power-on testing fixing component. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a wire harness power-on detection and fixing assembly, comprising a base plate, a manual switch mounted on the base plate, a wire harness fixing clamp mounted on the base plate, a detection device mounted on the base plate, the detection device having conductive terminals, an insulating sheath covering the conductive terminals, the conductive terminals and the wire harness fixing clamp being located on the same horizontal plane, and a cooling assembly mounted at the bottom of the conductive terminals.

[0005] The cooling component includes a cooling pipe, which is mounted on a base plate. Both ends of the cooling pipe are connected to the refrigeration box, and a heat-conducting plate is provided between the cooling pipe and the conductive terminal.

[0006] Preferably, the wire harness fixing clip has a U-shaped structure, and a connecting plate is provided at the bottom of the wire harness fixing clip. The four corners of the connecting plate are connected to the base plate by bolts, which facilitates the insertion and fixing of the wire harness and can clamp the wire harness from both sides to provide a stable fixing effect.

[0007] Preferably, the inner side of the wire harness fixing clip is provided with an arc-shaped part, which is used to clamp the wire harness. The arc-shaped part is provided with anti-slip texture, which matches the shape of the wire harness and can better fit the wire harness, making the wire harness more stable in the fixing clip, reducing the stress concentration of the wire harness during the testing process, and protecting the wire harness from damage.

[0008] Preferably, the conductive terminal is cylindrical, and one end of the conductive terminal is a socket for inserting the conductive end of the wire harness, which facilitates the insertion of the conductive end of the wire harness, realizes rapid connection, and improves detection efficiency.

[0009] Preferably, the heat-conducting sheet is made of aluminum alloy, and thermally conductive silicone is disposed between the heat-conducting sheet and the cooling pipe. Aluminum alloy has good thermal conductivity, which can quickly conduct the heat generated by the conductive terminal to the cooling pipe. At the same time, aluminum alloy has light weight and good mechanical properties, making it suitable for manufacturing heat-conducting sheets. Thermally conductive silicone has good flexibility and adhesion, which can tightly adhere to the surface of the heat-conducting sheet and the cooling pipe, ensuring that heat can be transferred efficiently.

[0010] Preferably, the base plate is made of polycarbonate or nylon, and the surface of the base plate is coated with an insulating coating to enhance its safety in humid environments or under high voltage conditions. The insulating coating can effectively prevent electric arcing or leakage on the surface of the base plate, providing more reliable insulation protection for the entire wire harness power-on detection and fixing assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During operation, the wire harness to be tested is placed inside the arc-shaped part of the wire harness clamp. The clamp automatically clamps the wire harness, and the arc-shaped design ensures a better fit and stability within the clamp. The conductive end of the wire harness is then inserted into the socket of the conductive terminal. The conductive terminal is cylindrical with a socket at one end, designed for quick connection of the wire harness and ensuring good electrical contact. Power is then switched on manually to energize the wire harness. The testing equipment uses the conductive terminal to perform energization testing on the wire harness, determining its conductivity and other performance indicators. When the wire harness is energized, the conductive terminal generates heat. The heat-conducting plate at the bottom of the conductive terminal quickly conducts heat to the cooling pipe. The two ends of the cooling pipe are connected to the cooling box. The coolant in the cooling box circulates through the cooling pipe. After being cooled in the cooling box, the coolant absorbs the heat conducted from the conductive terminal through the cooling pipe and then returns to the cooling box for further cooling. This quickly removes the heat generated by the conductive terminal, effectively reducing its temperature and preventing overheating damage due to excessive current. After the testing equipment completes the wire harness test, the power is cut off by a manual switch to stop the wire harness from being energized. The wire harness is then released by manually pinching the end of the wire harness clamp. This achieves stable wire harness fixation, efficient power-on testing, and effective heat dissipation and cooling, significantly improving the efficiency and safety of wire harness testing while extending the equipment's service life.

[0024] Working principle: During operation, the wire harness to be tested is placed in the arc-shaped part of the wire harness fixing clamp 2. The wire harness fixing clamp 2 automatically clamps the wire harness. The arc-shaped design can better fit the wire harness and ensure that the wire harness is stable in the fixing clamp.
