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

Abstract

A connector with a measurable insertion distance includes a connector plug and a connector socket, one or more sets of capacitive displacement sensors are correspondingly arranged on the connector plug and the connector socket, and the capacitive displacement sensor includes a pin terminal and a socket. Hole terminal; when the connector is inserted, the pin insulating head is in sliding contact with the jack electrode, and the jack insulating sleeve is in sliding contact with the pin electrode, so that the pin electrode and the jack electrode have no electrical contact and there is a radial gap. The invention also discloses a method for testing the insertion distance, which is used for testing and judging whether the insertion distance of the connector is in a set area. The invention tests and judges whether the insertion distance of the connector is in the set area through the capacitive displacement sensor and the detection circuit at the device end, so as to eliminate the failure of the device to work and damage to the connector caused by the incomplete insertion of the connector or the skewed insertion. , as well as possible hidden quality problems, and it is also convenient to identify the reliability of the connector connection when the equipment is overhauled.

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 ...
