Abstract

The invention relates to an end surface contact type rotary electric connector which comprises a fixed insulating plate and a rotating insulating plate. The fixed insulating plate and the rotating insulating plate are arranged coaxially and opposite to each other; one side of one of the fixed insulating plate and the rotating insulating plate, which faces to the other one, is provided with a circular groove which shares the same axis, and the one side of the other one is provided with an elastic contact terminal; a conductive slip ring is fixed and embedded in the circular groove; the elastic contact terminal is provided with a connecting part and a contact part; the connecting part is fixed and matched with the insulating plate provided with the elastic contact terminal; the contact part is matched with conductive slip ring in a sliding and pressing way when the rotating insulating plate rotates along with a corresponding rotating component; and the contact part is raised from the surface of one side of one insulating plate provided with the contact part, which faces to the other insulating plate. The end surface contact type rotary electric connector solves the problem that the existing rotary electric connector can not be applied to the occasion that the distance between a fixed component and a rotary component which need to be connected is short.

Description

technical field [0001] The invention relates to an electrical connection accessory, in particular to a rotary electrical connector with end face contact. Background technique [0002] With the integration and modularization of electrical and communication equipment, electrical connectors have been more and more widely used. When it is necessary to transmit current and signals between a fixed part and a rotating part, the more commonly used method is to use a rotary electrical connector. Most of the existing rotary electrical connectors include a cylindrical shell and a coaxial Rotate the core sleeve assembled in the shell, the core sleeve is coaxially provided with a conductive slip ring, and the shell is equipped with a brush, when in use, fix the shell on a fixed part and connect the brush with the corresponding The components are electrically connected, the core sleeve is fixed on the rotating part and the conductive slip ring is electrically connected to the correspondi...
