Description

Technical Field

[0001] This application relates to the technical field of fixtures, and in particular to a tooling fixture for cable testing. Background Technology

[0002] After cable production is completed, it is usually necessary to test the cable's performance, reliability, and safety to detect defects in advance and ensure normal use. In scenarios such as tensile testing, withstand voltage testing, and insulation testing, tooling fixtures are required to securely hold the cable.

[0003] Currently, Chinese patent CN107727518A discloses a cable performance testing device and a testing method using the same. The device includes a control console and clamping mechanisms on both sides. The clamping mechanisms include a mechanical chuck, a tightening nut, and a chuck shaft. The chuck shaft is a hollow shaft. The clamping mechanisms are symmetrically arranged on both sides of the control console and are used to clamp and fix the two ends of the cable to be tested.

[0004] Because the clamping mechanism can only clamp both ends of the cable, it cannot be used when the two ends of the cable do not need to be clamped and only the sidewall of the cable is clamped. Therefore, its applicability is relatively low. Utility Model Content
