Thermal pluggable electric connector

Abstract

The invention relates to a thermal pluggable electric connector. The thermal pluggable electric connector comprises a plug shell, a socket shell, a jack contact part, a contact pin contact part and asupporting spring coil; an insulating substrate A and an insulating substrate B are arranged in the plug shell and the socket shell respectively; the jack contact part is embedded in the insulating substrate A through the supporting spring coil; the contact pin contact part is embedded in the insulating substrate B through the supporting spring coil; and the contact pin contact part is movably inserted in the jack contact part. By adoption of the technical scheme provided by the invention, when the plug and the socket are connected in a matching manner, the matching precision between the contact pin contact part and the jack contact part is improved, so that electrical connection reliability is improved; and electric arc generated by inserting connection is lengthened under the magnetic force effect of magnetic steel and scattered along an arc guiding angle, so that electric arc extinguishing is accelerated, arc time is shortened, the jack contact region is protected effectively, reliable electric connection is realized, the service lives of the plug and the socket are prolonged, and the plug and the socket are protected.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, in particular to a hot-swappable electrical connector. Background technique [0002] At present, in all aspects of people's daily life, in order to realize the connection between electrical input and output, electrical connectors are often used, and the common ones mainly include socket shells (2), plug shells, and MC connectors. The number of phases of power or transmission current has a different number of contacts. In various electronic products, these electrical connectors are widely used and are the main functional components of electronic products. With the development of electronic technology, in many precision For electronic products, the requirements for assembly accuracy and connection reliability of electrical connectors are increasing day by day. However, when the existing electrical connectors are in use, electric sparks, arcing and other discharges will inevitably occ...

Problems solved by technology

The principle is to separate the pre-conduction section when the product is mated from the conduction section during operation, and the arc only affects the pre-conduction section, thereby realizing hot swapping; however, although this contact piece separates the conduction section of the contact piece Separated from the working section, the service life of the contact is improved, but the structure is complex and the volume is large; another example, the patent document with the publication number "CN104183943A" discloses a contact that supports hot plugging and a contact that uses the contact. Electrical connector, the contact piece includes a female sleeve and a contact spring set in the female sleeve. The female sleeve includes a front sleeve and a rear sleeve that are fixedly connected together. The front sleeve is made of arc-extinguishing material and has a The contact structure is in electrical contact with the matching contact piece, the contact structure is located in front of the contact reed, and the contact reed is fixedly connected with the rear sleeve

The principle is that when the pin is inserted, it first passes through the front sleeve, and the material of the front sleeve is made of arc-extinguishing material, which can effectively shorten the discharge time and avoid ablation of the pin and the front sleeve; The sleeve contacts the adapter contact first, and then the adapter contact contacts the contact reed, which protects the contact reed from arc ablation, but this kind of contact also has problems such as complex structure and large volume, and this kind of contact The structure needs special arc-extinguishing material as the front cover, which increases the product cost
