Vibration test clamp

Abstract

The invention relates to a vibration test clamp which comprises an adapter plate, mounting cushions, a regulation assembly and fasteners. The adapter plate is used for being arranged on a vibration table. The mounting cushions are arranged on the adapter plate, and each mounting cushion is used for fixing one connection terminal of a cable assembly. The regulation assembly is arranged on the adapter plate and is separated from the mounting cushions; the regulation assembly comprises mounting pillars; the mounting pillars are rotatably connected with the adapter plate; first fastening holes areformed on the mounting pillars; and each mounting pillar can rotate to the first fastening hole to be opposite to a second fastening hole of the other connection terminal of the cable assembly. Eachfastener passes through the corresponding first fastening hole and the second fastening hole of the other connection terminal of the cable assembly to fix one connection terminal of the cable assemblyon the mounting cushion. When each cable assembly is fixed to the vibration test lamp to carry out a vibration test, the pressing connection position of each connection terminal and a cable body is difficult to loosen. Moreover, the cable assemblies are difficult to suffer from unnecessary damage, and accuracy of a vibration test result is ensured.

Description

technical field [0001] The invention relates to the technical field of vibration tests, in particular to a vibration test fixture. Background technique [0002] The vibration test of the cable assembly is a test used to evaluate the vibration resistance of the equipment in its expected transportation and use environment, and it is an important part of the reliability test of the cable assembly. The cable assembly includes a cable body and connection terminals crimped at both ends of the cable body. Most of the cable assemblies tend to have a large difference in the crimping angle of the connecting terminals at both ends during the sample preparation process, while the traditional vibration test fixture will directly twist the connecting terminals at both ends in order to fix the cable assembly on the adapter plate The fastening holes to the connecting terminals are opposite to the fastening holes on the adapter plate, and then the connecting terminals are forcibly tightened...

AI Technical Summary

Problems solved by technology

Most of the cable assemblies tend to have a large difference in the crimping angle of the connecting terminals at both ends during the sample preparation process, while the traditional vibration test fixture will directly twist the connecting terminals at both ends in order to fix the cable assembly on the adapter plate The fastening holes to the connection terminals are opposite to the fastening holes on the adapter plate, and then the connection terminals are forcibly tightened and fixed with bolts

However, in this kind of vibration test fixture, the connecting terminals at both ends of the cable assembly will bear relatively large torsional stress and tensile force, so that the crimping place between the connecting terminal and the cable body is easily loosened during the vibration test, and even the cable body may be damaged. Fracture or connection terminal deformation, cracking and other problems
