Description

Technical Field

[0001] This utility model relates to the field of wire waterproof performance testing equipment, and in particular to a wire waterproof performance testing fixture. Background Technology

The principle is to connect the male and female connectors of the XLR cable into the sockets on both sides of the fixture, introduce air through the air inlet on the right side, and immerse the tail terminal of the XLR cable in water to test the waterproof performance of the XLR cable. However, due to the large gap between the sockets and the male and female connectors, the airtightness of the air inlet in the air-inlet fixture is weakened, making it impossible to reasonably verify the waterproof performance of the XLR cable. Utility Model Content

[0003] The purpose of this invention is to provide a wire waterproof performance testing fixture to solve the technical problem in the prior art where the air tightness between the wire and the air inlet gauge weakens, thus making it impossible to reasonably verify the waterproof performance of XLR wire.

[0018] Reference Figure 1 and Figure 2 A wire waterproof performance testing fixture according to an embodiment of the present invention includes a housing 100, a cover 200, an air inlet pipe 300, and a waterproof connector 400. The housing 100 has an inner cavity 110, and an insertion hole 120 is provided on the surface of the housing 100. The cover 200 is detachably installed on the housing 100 and closes the inner cavity 110. The air inlet pipe 300 is fixedly connected to the housing 100, one end of the air inlet pipe 300 is connected to an air source, and the other end is connected to the inner cavity 110. The waterproof connector 400 is detachably inserted into the insertion hole 120, and the waterproof connector 400 and the insertion hole 120 are sealed together.

[0019] In practical use, the waterproof connector 400 is inserted into the socket 120 on the surface of the housing 100 to ensure a sealed connection. The wire to be tested is cut in the middle, and the two ends passing through the waterproof connector 400 are inserted into the inner cavity 110 of the housing 100. The male and female ends of the XLR wire are connected. The cover 200 is installed on the housing 100 to seal the inner cavity 110. Then, the air inlet pipe 300 is connected to the air source device to complete the pre-testing process of the wire waterproof performance testing fixture. The assembled wire and testing fixture are placed in water, and the testing fixture and the wire to be tested are submerged in water. Then, a certain pressure of gas is injected into the inner cavity 110 through the air source device, and it is observed whether any bubbles are generated. By ensuring that there are no gaps between the wire and the testing fixture, interference factors in the testing process are eliminated. When the inner cavity 110 is filled with pressurized gas, if the waterproof performance of the wire is poor, the gas will leak through the gaps in the wire. Utilizing the visibility characteristics of water, the leaked gas forms bubbles in the water, which is easy to observe and judge.

[0020] In summary, during the testing of XLR cables, the cable and the waterproof connector are sealed together with a 400mm seal, and then the mating male and female connectors are connected to ensure that there are no gaps between the cable and the testing fixture. This allows for more accurate verification of the waterproof performance of the XLR cable during the immersion test.

[0021] In some embodiments, refer to Figure 2 and Figure 3 A sealing ring 500 is provided between the housing 100 and the cover 200, and the inner cavity 110 is located within the sealing ring 500. This further improves the sealing performance between the housing 100 and the cover 200, ensures the sealing of the inner cavity 110, reduces the possibility of gas leakage, protects the pressure environment in the inner cavity 110, and improves the accuracy of the test results. It should be mentioned that a sealing groove 130 is provided on the side of the housing 100 facing the cover 200, and the sealing ring 500 is embedded in the sealing groove 130. The side of the cover 200 facing the housing 100 abuts against the sealing ring 500. The sealing ring 500 is constrained by the groove wall in the sealing groove 130, which restricts its horizontal movement and ensures the accuracy of the sealing position. When the cover 200 abuts against the sealing ring 500, the sealing ring 500 is subjected to vertical pressure, undergoes elastic deformation, fills the tiny gaps between the sealing surfaces, and improves the sealing effect.

[0022] In some embodiments, refer to Figure 2 The cover 200 has a receiving cavity 210, which corresponds to the inner cavity 110. The bottom of the inner cavity 110 abuts against the end of the waterproof connector 400. The receiving cavity 210 is located within the sealing ring 500. In actual use, the section of the wire inserted into the inner cavity 110 needs to abut against the bottom of the receiving cavity 210 to ensure that the wire passes through the waterproof connector 400 and extends into the inner cavity 110. The receiving cavity 210 and the inner cavity 110 provide ample space for the wire to extend in, and also provide sufficient space for the gas used for inflation, allowing the user ample time to test whether the waterproof performance of the wire complies with regulations.

[0023] In some embodiments, the cover 200 is fixedly connected to the housing 100 by screws (not shown). This facilitates disassembly and assembly; specifically, refer to... Figure 4 The cover 200 has clearance grooves 220 on both sides, and the housing 100 has multiple first screw holes 140. Multiple second screw holes 230 are provided within the clearance grooves 220. When the cover 200 is closed onto the housing 100, the first screw holes 140 and second screw holes 230 correspond one-to-one, and screws are inserted into the first screw holes 140 and second screw holes 230. The clearance grooves 220 provide sufficient operating space for screw installation and removal. The corresponding design of the multiple screw holes ensures a more stable connection between the cover 200 and the housing 100. Simultaneously, the clearance groove design prevents screws from protruding from the surface of the cover 200, ensuring aesthetics while facilitating the placement of the entire testing fixture.

[0024] In some embodiments, a flexible hose (not shown) is detachably fitted to the end of the air intake pipe 300, and the hose is connected to an air source. The use of the hose increases connection flexibility, facilitates the placement of the testing fixture, and the detachable design allows the hose to be reused, reducing costs.

[0025] In some embodiments, refer to Figure 2 The insertion hole 120 and the waterproof connector 400 are fixedly connected by threads. The fixed connection is achieved by the interlocking of the threads between the waterproof connector 400 and the insertion hole 120. At the same time, the threaded connection can achieve a sealing effect, prevent gas leakage, and ensure the stability and reliability of the entire testing fixture during the testing process.

[0026] For those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the scope of protection of this utility model.
