Description

Technical Field

[0001] This utility model relates to the field of cable testing equipment technology, and in particular to a multi-type cable testing fixture. Background Technology

[0002] Cable inspection is the process of checking the quality and performance of transmission carriers such as wires and cables. It mainly involves methods such as visual inspection, continuity testing, insulation resistance measurement, and withstand voltage testing to check for problems such as damage, aging, short circuits, and poor insulation in the cables. Current cable testing lacks dedicated fixtures suitable for various types of cables. During testing, manual operation can easily lead to incorrect wire connections, resulting in low efficiency and accuracy. Furthermore, the interfaces have poor expandability and lack visual observation methods. When testing multiple cables simultaneously, after connecting the corresponding plugs at both ends of the cables, the longer cables tend to accumulate and tangle around the fixture due to their different lengths. This not only occupies operating space but may also become entangled with other cables, interfering with the testing process and increasing the risk of accidental contact. In addition, tidying up the messy cables consumes extra time and reduces the efficiency of batch testing. Utility Model Content

[0003] The purpose of this invention is to provide a multi-type cable testing fixture that can effectively solve the problems in the background art.
