Abstract

A self-lubricating pin contact belongs to the technical field of electrical connectors. A self-lubricating pin contact of the present invention includes a pin contact body. The self-lubricating pin contact further includes a conductive grease and a movable elastic caging device. A central hole is horizontally disposed in the pin contact body from front to back, the central hole leads to a rear endof the pin contact body, a front end of the pin contact body is closed, the front end of the pin contact body is a plug end, a plurality of holes communicating with the central hole are disposed on asidewall of the plug end of the pin contact body, the central hole of the pin contact body is filled with the conductive grease at the plug end, the movable elastic caging device is disposed in the central hole of the pin contact body, and the movable elastic caging device can push the conductive grease to move toward the plug end. The present invention is applied to an electrical connector, so that a plugging and unplugging life of the contact of the electrical connector can be improved.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, in particular to a self-lubricating pin contact piece. Background technique [0002] In recent years, with the continuous improvement of the service life of the aerospace and aviation complete machine systems, the requirements for the plugging life of the electrical connector contacts are also continuously increasing. The main difficulty of plugging life is how to reduce wear while ensuring sufficient positive pressure, so as to slow down the increase of contact resistance and ensure the reliability of contact. [0003] The traditional contact parts have no lubrication function. In order to ensure the reliability of the contact, it is necessary to ensure that there is sufficient positive force between the contact pairs, and the positive force is proportional to the wear, which means that it is difficult to reduce the wear to ensure the reliability of the contact. The service life o...
