Abstract

The switching equipment used for detecting the breaking, insulation and pressure enduring performance of a cable network relates to the switching equipment in the electronics test technical field. The problems to be solved are that: the switching equipment used for detecting the breaking, insulation and pressure enduring performance of the cable network is provided, the technic proposal comprises: a switching cable, a switching plug group, a switching cable, a test mouth group and an extension test mouth; one end of the switching cable is connected with a N route test signal produced by a test instrument, another end thereof is connected with the switching plug group, the output end of the switching plug group is connected with the switching cable, the output ends of the switching cable are respectively connected with each test plug group of the test mouth group and the extension test mouth in parallel, the output ends of the shunt-wound test mouth group and the extension test mouth are connected with the external tested cable and the cable network. Using the switching equipment, the test signal can be extended to an M times test signal group, and can provide a combination test of the non-homologous supply test signals, the test range is expanded and the test efficiency is improved.

Description

1. Technical field: [0001] The utility model belongs to the field of electronics inspection technology and relates to a switching device for inspecting the on-off, insulation and voltage-resistant performance of a cable network. 2. Background technology: [0002] In modern high-tech equipment, electronic products with powerful functions, precise control, and reliable operation account for a large proportion. Each electronic device must be connected by various dense cables and cable networks to form an electronic system. Therefore, the correctness and reliability of cables and cable network connections play an important role in ensuring the reliable operation of the entire electronic system. [0003] The automatic inspection of the conduction, insulation and withstand voltage performance of cables and cable networks is an indispensable link in the cable assembly and production process. A small defect in the cable network may be the fatal reason for the failure of the entire ...

AI Technical Summary

Problems solved by technology

The 256-channel test signal 2 sent by the tester is connected to the external tested cable and cable network. The inherent test method of the instrument can only provide a test plug combination with a total test point less than or equal to 256, and after the plug combination is fixed, Once the cable plug model under test does not match it, it is necessary to destroy the original plug combination, redistribute the test signal to the lead welding new plug group, and because the tester can provide a maximum of 256 test points, so It cannot adapt to the test requirements of various equipment cables and specific network systems, which greatly limits the use of the tester
