Problems solved by technology

[0003] 1. Due to the design and manufacturing error of the chassis, the electrical connector cannot be mated in place or the mating force is too large;
[0004] 2. The locking force of the electrical connector is large, so that the mating is not in place, such as a threaded or snap-in circular electrical connector with a large shell size;
[0005] 3. The tail of the electrical connector drags a very thick cable, causing the electrical connector to be deflected;
[0006] 4. As an integrated electrical connector for the interconnection interface between devices, it is also prone to mating deflection in the process of blind mating
The existing electrical connectors do not have the function of detecting the mating distance of plugs and sockets. Therefore, it is necessary to design a detection structure for the mating distance of plugs and sockets in the electrical connector, so that it has the function of detecting the mating distance between plugs and sockets. detection function

Abstract

An electrical connector with a measurable mating distance, including a connecting plug and a connecting socket, and one or more sets of resistance displacement sensors are correspondingly arranged on the connecting plug and the connecting socket, and the resistance displacement sensors include pin terminals and jack terminals, The resistor pins on the pin terminals are electrical conductors with a resistance value. When the electrical connectors are mated, the outer wall of the resistor pins slides and electrically connects with the inner wall of the socket electrode port. The invention also discloses a method for testing the mating distance, which is used for testing and judging whether the mating distance of the electrical connector is within a set area. The invention tests and judges whether the mating distance of the electrical connector is in the set area through the resistance displacement sensor and the detection circuit at the equipment end, thereby eliminating the inoperability and damage of the equipment caused by the improper mating of the electrical connector or the skewed mating Electrical connectors, as well as potential quality hazards, are also convenient for identifying the reliability of electrical connector connections during equipment maintenance.

Description

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