High-voltage connector

Abstract

The invention discloses a high-voltage connector, which comprises a high-voltage male end plug and a high-voltage female end plug which are mutually matched, wherein the high-voltage connector is characterized in that more than two lantern-type metal spring sheets sleeve the high-voltage male end plug; a fixed end is arranged at one end of each metal spring sheet and an open end is arranged at the other end; a contact strip is arranged on each metal spring plate at the open end and is bent outwards to deform; and when the high-voltage male end plug is inserted into the high-voltage female end plug, the contact strip of each metal spring sheet and an inner hole wall of the high-voltage female end plug are in press fit. The high-voltage connector is simple and light in structure, and the contact area of the male end plug and the female end plug is stable.

Description

technical field [0001] The invention relates to an improved invention of a high-voltage connector, in particular to an improved invention of a high-voltage connector that can be plugged in quickly and withstands high current. Background technique [0002] At present, there are more and more high-current applications under high voltage. High-voltage connectors require that the male and female plugs must ensure that the microscopic area where the silver-plated layers of the male and female terminals are in contact with each other when the contact resistance is small. There is enough contact area, but often after high current passes through the contact point of the male and female ends, due to the limited microscopic contact area, high temperature will be generated locally, the silver plating layer of the male and female ends will be damaged, and the contact resistance will become larger, and the silver plating layer of the male and female ends will interact with each other.

Problems solved by technology

The existing technology adopts the following schemes to overcome it. Scheme 1: Adopt the plug-in structure of low-voltage connector inserts and reeds, increase its size to ensure the bonding area after mating, and there are problems: the size of the connector is too large, and the male and female ends are plated. The microscopic area where the silver layers contact each other is limited, which can satisfy the limited current passing through.

Solution 2, using a single lantern plug-in structure (fixed at both ends), increasing the interference to ensure the fit area after mating, there is a problem: in order to obtain a sufficient fit area, it is necessary to increase the interference of the male and female ends, so It will cause the insertion and extraction force of the male and female ends to increase, and at the same time, the friction force will increase, which will accelerate the wear of the coating at the joint position of the male and female ends.
