Electric connector with contact element with surface abrasion prevention function and plugging and unplugging method thereof

Abstract

The invention discloses an electric connector with a contact element with a surface abrasion prevention function and a plugging and unplugging method thereof. A plating layer on the surface of a contact element of an existing electric connector is abraded in the plugging and unplugging process of the contact element. Each reed mounting hole formed in an insulator is composed of a conical hole anda cylindrical hole; a non-uniform-section slotted reed and a spring are arranged in each reed mounting hole; the inner side surfaces of two elastic sheets of each non-uniform-section slotted reed arerespectively provided with a non-uniform-section slotted reed inner plating layer; a contact pin fixed to an upper housing is provided with a contact pin outer plating layer; and the maximum size of the cross section of the contact pin outer plating layer is smaller than or equal to the minimum inner diameter of a hollow circular truncated cone shape defined by the non-uniform-section slotted reedinner plating layers on the inner sides of the two elastic sheets. According to the invention, the taper holes and the non-uniform-section slotted reeds are used to reduce the abrasion of the surfaceof the contact element for realizing electric connection in the plugging and unplugging process, and the non-uniform-section slotted reeds made of a wear-resistant material are used to realize frictional abrasion, so that the service life of the electric connector is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, and in particular relates to an electrical connector with a contact piece with the function of preventing surface abrasion and a plugging method thereof. Background technique [0002] Electrical connectors are an essential interface component for transmitting electrical energy and signals. They have a wide range of applications, a considerable number, and an important position in equipment systems in aviation, aerospace, weapons, electronics and other industrial sectors. The contact failure of electrical connectors accounts for about 45.1% of the total failures, and part of the cause of failure is the wear of the coating on the surface of the contacts during the plug-in process. The wear will also cause oxidation and corrosion on the surface of the contacts, which will reduce the contact performance of the contacts.

The contact failure of electrical connectors accounts for about 45.1% of the total failures, and part of the cause of failure is the wear of the coating on the surface of the contacts during the plug-in process. The wear will also cause oxidation and corrosion on the surface of the contacts, which will reduce the contact performance of the contacts. Affects the stability of electrical conductivity and signal transmission

[0003] At present, most contacts mainly rely on the elastic deformation of the reed structure of the slotted and closed socket to generate contact pressure. During the insertion and removal process, due to the large friction force, the coating on the surface of the contact will be worn and the contact will be promoted. Oxidation and corrosion on the surface of the parts are intensified, resulting in a decline in contact performance, and wear is unavoidable in the slotted and closed reed socket structure
