Automatic centering plugging method for electric connector

Abstract

The invention discloses an automatic centering plugging method for an electric connector. After an existing electric connector plugging device is abraded, the coaxiality of a socket and a plug of theelectric connector is reduced. The method comprises the steps that the transmitting ends of two photoelectric sensors are both fixed on an electric connector socket clamp, the receiving ends of the two photoelectric sensors are both fixed on an electric connector plug clamp, and the translation in two directions and rotation in one direction of the electric connector socket clamp are realized through the driving of an XZ-axis two-dimensional sliding table and a rotary servo motor; a master controller judges that the receiving ends of the two photoelectric sensors receive the infrared light emitted by the emitting ends of the photoelectric sensors, the positioning protrusions of the electric connector socket, the positioning grooves of the electric connector plug and the central axes of theelectric connector socket and the electric connector plug are judged to be aligned, and then an electric connector plugging and unplugging device carries out plugging and unplugging tests on the electric connector. According to the invention, the problem that the socket and the plug of the electric connector cannot be centered after the electric connector plugging device is plugged for multiple times, is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, and in particular relates to an automatic centering and plugging method for an electrical connector. Background technique [0002] Electrical connectors are important interface components for electrical connections, and are widely used in various fields such as aerospace, military industry, and electronics. The reliability of the electrical connector is directly related to the reliability of the entire system. Electrical connectors are usually stored in a constant temperature and humidity environment, and are regularly tested. Plugging and unplugging are required during testing. The main failure form in the storage environment is contact failure, and the parameter that characterizes its contact performance is contact resistance. In order to simulate engineering practice and evaluate the reliability level of electrical connectors, it is usually necessary to carry out accelerated tes...

AI Technical Summary

Problems solved by technology

In the actual application of the device, due to the long stroke of the socket, after repeated plugging and unplugging tests, the guide rail and other parts of the device are prone to wear, resulting in a decrease in the coaxiality of the electrical connector socket and plug, and deviations in the axis position , the plug and socket of the electrical connector cannot be centered, resulting in too much error, causing invalid tests and even unable to carry out accelerated tests
