Tool for testing service life of circular contact pair for electric connector

Abstract

The invention discloses a tool for testing the service life of a circular contact pair for an electric connector. The problem of automatic testing on the mechanical life of a contact pair for an electric connector is solved. The tool for testing the service life of the circular contact pair for the electric connector comprises an upper clamping head and a lower clamping mechanism matched with the upper clamping head for use, and the lower clamping mechanism comprises an installing frame and a step positioning frame arranged in an inner cavity of the installing frame; the installing frame is internally provided with a big rectangular frame and a small rectangular frame used for supporting a fixed plate, the fixed plate is provided with a circular through hole used for fixing a contact pair clamping plate A, an installing through hole for installing and placing a circular contact pair pin and a waist-shaped hole and a locating hole which are used for fixing a contact pair clamping plate B, and the symmetrical center points of the circular through hole, the installing through hole and the waist-shaped hole are located on the same axis; the contact pair clamping plate A and the contact pair clamping plate B are both circular plates, the circle center of the contact pair clamping plate A and the circle center of the contact pair clamping plate B are each provided with a fixing through hole, and multiple eccentric semi-circular holes are formed in the peripheral direction of the contact pair clamping plate A and in the peripheral direction of the contact pair clamping plate B respectively. By means of the tool for testing the service life of the circular contact pair for the electric connector, counting on the service life test of the contact pair is accurate and reliable, and the testing efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of life testing of electronic devices, and in particular relates to a tool for testing the life of an electrical connector contact pair. Background technique [0002] The application range of electrical connectors is very wide. It is a key component of electrical equipment, and the key component in electrical connectors is the contact pair. The main function of the contact pair is to ensure the continuity of the circuit between the current-carrying elements of electronic equipment. The only way to complete the transmission of electrical signals. The mechanical life of electrical connectors, especially the mechanical life of contact pairs in electrical connectors, is crucial to the design and key technology research of contact pairs. The mechanical life of the connector refers to the plug-in life, which usually has a specified value. When the specified mechanical life is reached, the contact resistance, insu...

Problems solved by technology

For all kinds of electrical connectors, especially automotive electrical connectors, the plugging life is generally required to be as high as 10,000 times. In this case, if the mechanical life test of the contact pair still relies on manual plugging and unplugging operation testing, it is not only time-consuming and laborious. The cost of testing is high, and operators are prone to fatigue, which affects the accuracy of test counting results
