Connector with testable plugging distance and plugging distance testing method

Abstract

A connector with a testable plugging distance comprises a connector plug and a connector socket. One or more groups of capacitive displacement sensors are correspondingly arranged on the connector plug and the connector socket, and each capacitive displacement sensor comprises a pin terminal and a jack terminal. When the connector is plugged, pin insulating heads are in sliding contact with jack electrodes, and jack insulating sleeves are in sliding contact with pin electrodes, so that the pin electrodes are not in electrical contact with the jack electrodes, and radial gaps are formed betweenthe pin electrodes and the jack electrodes. The invention further discloses a plugging distance testing method, which is used for testing the plugging distance of the connector and judging whether the plugging distance of the connector is in a set range or not. According to the invention, the plugging distance of the connector is tested and whether the plugging distance of the connector is in theset range or not is judged through the capacitive displacement sensors and a detection circuit at an equipment end, so that the problems of working failure of the equipment, damage to the connector and possible potential quality hazards due to the fact that the connector is not plugged in place or is plugged obliquely are solved, and the connection reliability of the connector can be distinguished conveniently during equipment overhaul.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a connector with a measurable mating distance and a testing method for the mating distance. Background technique [0002] The connector is an electromechanical component that can realize signal disconnection and conduction. If the mating is not in place, the signal will be blocked and the device will not work normally; if the mating force between the plug and the socket is too large, the use of the connector will be reduced. life, or even damage the connector. As a device interface connector, it often has the characteristics of large volume, many types of transmission signals, many cores, and blind plugging. This kind of connector often has the following problems during use: [0003] 1. Due to the design and manufacturing error of the chassis, the connector cannot be mated in place or the mating force is too large; [0004] 2. The locking force of the connector is large, so ...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the design and manufacturing error of the chassis, the connector cannot be mated in place or the mating force is too large;

[0004] 2. The locking force of the connector is large, so that the mating is not in place, such as a threaded or snap-in circular connector with a large shell size;

[0005] 3. The tail of the connector drags a very thick cable, causing the connector to be mated and deflected;

[0006] 4. As an integrated connector for the interconnection interface between devices, it is also prone to mating deflection in the process of blind mating

Existing connectors do not have the function of detecting the mating distance of plugs and sockets, so it is necessary to design a detection structure for the mating distance of plugs and sockets in the connector so that it has the function of detecting the mating distance between plugs and sockets
