Embodiment Construction

[0025] In order to describe the technical solution of the present invention more clearly and completely, the present invention will be further described below in conjunction with the accompanying drawings.

[0026] Please refer to figure 1 , The crown spring socket connector 1 provided by the specific embodiment of the present invention is used for the connection between the plug 2 and the socket 3 in a manual maintenance switch or an electrical connector. The crown spring socket connector 1 is arranged between the plug 2 and the socket 3 for preventing poor contact between the plug 2 and the socket 3 .

[0027] In this embodiment, the crown spring socket connector 1 is made of phosphor bronze, which has good ductility, current carrying capacity, electrical conductivity and impact resistance, so that the plug 2 and the jack 3 can perform operations such as live plugging and exceeding the rated current impact, without electric sparks, and at the same time, the crown spring soc...

Abstract

The invention proposes a crown spring jack connecting part, and relates to the technical field of electric connectors. The connecting part is used for manual maintenance of the connection between a plug and a jack in a switch or an electric connector. The connecting part is made of a phosphor copper material. The connecting part is shaped like bamboo. A crown spring jack comprises a plurality of annular base bodies and a plurality of elastic piece groups. The annular base bodies are arranged in parallel, and each two adjacent annular base bodies are connected through one elastic piece group to form one connection unit. Each connection unit is shaped like a waist drum. The internal surface of the central part of each elastic piece group is used for the contact connection with the plug. The external surfaces of the annular base bodies are used for the contact connection with the internal surface of the jack. Each elastic piece group consists of a plurality of elastic pieces, and the elastic pieces extend from one annular base body to the next annular base body in an inclined manner. According to the invention, the connecting part provided by the invention can enable the contact between the plug and the jack to be good, and the elasticity can be valid perpetually. Meanwhile, the connecting part is good in conductivity, and cannot generate arc in a working process.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a crown spring jack connector. Background technique [0002] The manual maintenance switch is a commonly used manual operation device in electric vehicles. It is generally used to cut off the high-voltage equipment in an emergency when the electric vehicle needs maintenance. A general manual maintenance switch includes a fuse, a plug end and a jack end, the fuse is connected to the plug end, the jack end is connected to an external high-voltage circuit, and the plug end is connected to the jack end by manual operation The fuse can be connected to an external high-voltage circuit, so as to protect the high-voltage circuit. [0003] Generally, in order to prevent poor contact between the plug and the jack, a power contact insert is provided between the plug and the jack, but this structure has potential safety hazards, and an arc will be generated when the plug is in...
