Easy-cleaning long-life elastic contact structure

Abstract

The invention discloses an easy-cleaning long-life elastic contact structure which comprises a pin base member and a jack base member. The connection mode in which the semi-circular ball end of the pin contact member on the pin base member touches the arc-shaped cavity of the jack contact member on the jack base member is adopted. According to the method, the contact between the pin contact memberand the jack contact member is in non-friction contact, the contact member is not worn, the contact reliability of the contact member is maintained through the elastic force provided by the spring and the service life of the contact member is prolonged. The semi-spherical end of the pin contact member on the pin base member is in contact with the arc-shaped cavity of the jack contact member on the jack base member. As the jack contact member changes the traditional deep hole design so that cleaning of dust, water vapor and other sundries existing on the surface of the contact can be facilitated, wearing and falling off of the coating on the surface of the contact can be avoided and the working reliability of the contact can be improved.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to an easy-to-clean and long-life elastic contact structure. Background technique [0002] The contact parts of traditional connectors are generally elastic jacks and rigid pins or elastic pins and cylindrical jacks. The contact principle is generally that the pin contacts are inserted into the jack contacts, and through the jacks The elastic part inside or the elastic part on the pin provides radial positive pressure to ensure the contact reliability. During actual insertion and extraction, due to the large friction around the contact part, it will lead to increased wear during long-term use. , The friction force is reduced until the phenomenon of contact failure occurs. In addition, the sockets of this type of contact are generally arranged inside the shell in the shape of deep holes. During use, if there is pollution from dust, water vapor and other debris, There i...

[0002] The contact parts of traditional connectors are generally elastic jacks and rigid pins or elastic pins and cylindrical jacks. The contact principle is generally that the pin contacts are inserted into the jack contacts, and through the jacks The elastic part inside or the elastic part on the pin provides radial positive pressure to ensure the contact reliability. During actual insertion and extraction, due to the large friction around the contact part, it will lead to increased wear during long-term use. , The friction force is reduced until the phenomenon of contact failure occurs. In addition, the sockets of this type of contact are generally arranged inside the shell in the shape of deep holes. During use, if there is pollution from dust, water vapor and other debris, There is a problem that it is difficult to clean. The long-term friction between the pin of the contact and the socket of the contact will not only cause serious wear of the contact part, but also cause serious problem of the plating layer of the contact falling off.
