Description

Technical Field

[0001] The present invention belongs to the field of aircraft assembly in aviation manufacturing engineering, and relates to a universal plug measuring connector, which is used for cable continuity testing during aircraft assembly and debugging. It can effectively fix the plug of any cable for connection, and assist in completing the cable continuity test. It has universality and meets the use requirements of cable testing. Background Art

[0002] Since a lot of debugging and testing work is required during the aircraft assembly and debugging process, and most of the debugging and testing tasks require the use of various related equipment, and each device has its own dedicated test cable, there are many types of equipment and the types of cables used are relatively complex.

[0003] The premise for each test to proceed smoothly is to ensure that the test equipment and test cables are in good condition. The test equipment itself usually has a self-test function to ensure that it is in good condition before use, but the test cables are usually difficult to test. In recent years, aircraft failures caused by test cable problems have occasionally occurred. Therefore, it is very necessary to conduct relevant inspections on the test cables of various test equipment before use. However, according to the traditional method, since the cables under test are basically different, the test instrument can only use different adapter cables to connect the cables under test. The number of adapter cables required for the number of cables under test not only increases the test cost, but also requires a lot of space for storage. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a universal plug measuring connector. According to the size and shape characteristics of the plugs of the debugging and testing equipment cables during the aircraft assembly and debugging process, the universal plug measuring connector is designed and manufactured. The plugs at both ends of the cable to be tested are respectively connected to the universal connector for fixation, and then the test instrument is connected to the equipment connector of the invention to start the test, thereby realizing the universality of plug docking and eliminating the need for adapter cables. The connector is easy to use and is extremely easy to connect and fix, thereby facilitating the rapid completion of cable testing, making the entire testing work convenient and efficient.
