Comprehensive insulation and voltage resistance testing device of electric connector

Abstract

The invention relates to a comprehensive insulation and voltage resistance testing device of an electric connector. Contact couples of electric conversion connector interfaces, which are connected with the electric connector to be tested, are divided into four test groups in a staggered row and staggered column mode; in the four test groups, a testing cable switches a common output interface connected with a testing power supply; a sequential control circuit controls the transverse short circuiting of the four test groups to test the transverse voltage of the contact couples, the longitudinalshort circuiting of the four test groups to test the longitudinal voltage of the contact couples and the short circuiting of the four test groups to test voltage between the contact couples and a casing; and the comprehensive results of the testing voltage in the transverse direction and the longitudinal direction and between the contact couples and the casing are compared with insulation parameters and dielectric withstand voltage parameters which are set in a control system to complete the performance testing of an electric connector product to be tested. The invention has the advantages offew testing steps, short fixed conduction time, large testing quantity within unit time, high testing efficiency and testing degree of automation, accurate control of testing time, ensured voltage increase time of insulation and dielectric withstand voltage and accurate testing result.

Description

technical field [0001] The invention relates to the field of electrical connector testing devices, in particular to a testing device for testing the comprehensive performance of insulation and voltage resistance of electrical connectors. Background technique [0002] The insulation resistance and withstand voltage resistance of electrical connector products are the most basic electrical parameters to ensure the reliable operation of electrical connectors. Therefore, insulation resistance testers and withstand voltage testers must be used to detect electrical parameters such as insulation and withstand voltage of electrical connectors. , to determine whether the insulation resistance and withstand voltage between all contact couples and between the contact couple and the shell are qualified. Usually, the instrument needs to be replaced every time a parameter is measured. The speed is slow, the efficiency is low, and it is easy to make false detections and missed detections. ...
