Embodiment Construction

[0020] Embodiments of contacts that support hot swapping, such as Figure 1-2 As shown, the front end of the contact piece is the plug-in end, which includes a female sleeve and a contact spring 101 disposed in the female sleeve.

[0021] The female sleeve includes a front sleeve 102 and a rear sleeve 103 which are fixedly connected together. The front sleeve 102 is made of an arc-extinguishing material, specifically Be material, and its front part is provided with a contact structure for electrical contact with an adapter contact. The structure is located in front of the contact spring 101. In this embodiment, the contact structure is specifically composed of two cantilever-type elastic contact fingers 104 arranged at the front end of the front cover 102, wherein the elastic contact fingers 104 are formed through the front cover 102. The front end of each elastic contact finger 104 is formed after splitting grooves, and each elastic contact finger 104 is provided with a conve...

Abstract

The invention relates to electric connector field and especially to a contact member supporting hot plug and an electric connector using same. The contact member comprises a mother sleeve and a contact reed disposed in the mother sleeve. The mother sleeve comprises a front sleeve and a back sleeve fixedly connected together. The front sleeve is produced by arc extinguishing material and the front end of the front sleeve is provided with a contact structure used for electrically contacting an adaptive contact member. The contact structure is arranged in the front of the contact reed. The contact reed is fixedly connected with the back sleeve. When contact member and the adaptive contact member are plugged, the adaptive contact member firstly passes the front sleeve. The front sleeve is produced by the arc extinguishing material so as to be capable of effectively shortening discharging time and preventing the adaptive contact member and the front sleeve from being ablated. As a result, the contact performance of the contact member can be effectively protect after the contact member is subjected to hot plug, and a problem is solved that a conventional crowned hole contact member may burn out the contact reed because of hot plug.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a contact piece supporting hot plugging and an electrical connector using the contact piece. Background technique [0002] With the continuous increase of the power that the electrical connector can carry, its application in power supply equipment is also becoming more and more extensive. In some power supply equipment, it is often necessary to supply power to multiple modules at the same time. For example, the power supply equipment used in communication equipment supplies power to multiple modules at the same time. , you need to unplug the problematic module directly, because once the entire power supply is unplugged, it will cause a power outage of the entire device, which in turn will cause the interruption of the telecommunication signal in a local area, so the unplugging of the problematic module is in the live state It is carried out under, that is, forced hot pluggin...
