Abstract

The invention relates to an auxiliary fixing clamp for test joints. The auxiliary fixing clamp comprises a first clamp body, a second clamp body, a connection shaft, a clamping spring, a first elasticarm, a second elastic arm and a fixing device, wherein the first clamp body and the second clamp body are connected through the connection shaft; the connection shaft is sleeved by the clamping spring; two extension ends of the clamping spring respectively press the first clamp body and the second clamp body to ensure that the first clamp body and the second clamp body are located in a clamping state; the handheld ends of the first clamp body and the second clamp body are respectively connected with one end of the first elastic arm and one end of the second elastic arm; the other end of the first elastic arm and the other end of the second elastic arm are respectively connected with the fixing device; after the connection, an included angle formed by the clamping ends of the first elasticarm and the second elastic arm is smaller than 180 degrees; the fixing device is used for fixing test joints; and a through hole for the passing of the test joints fixed by the fixing device is formed in the connection shaft. The auxiliary fixing clamp is capable of ensuring that the contact between test joints and to-be-tested terminals on terminals strips is stable and effective during breakertest.

Description

Technical field [0001] The invention relates to the field of power test auxiliary devices, and more specifically, to an auxiliary fixing clip for a test joint. Background technique [0002] The terminal block means the insulating part that carries multiple or more sets of mutually insulated terminal assemblies and is used to fix the support; the function of the terminal block is to connect the lines of the equipment in the screen and the equipment outside the screen to play a signal (current and voltage) The function of transmission; with the terminal block, the wiring is beautiful and easy to maintain. The connection between the long-distance lines is mainly reliable, and the construction and maintenance are convenient. [0003] In the circuit breaker test, the circuit breaker is usually tested with the terminal from the circuit breaker to the terminal block as the test contact; however, during the test process, the worker needs to hold the test connector by hand to prevent it fro...
