Abstract

The invention relates to a self-locking pushing mechanism of an electric connector, which comprises a supporting frame fixed on a hook body, a guide frame, a pushing cylinder fixedly arranged on the supporting frame, the electric connector sleeved on the guide frame, and a connecting rod connected with the pushing cylinder and the electric connector, wherein the connecting rod consists of a driving shaft, a driving shaft rotating arm and a telescopic rod rotating arm; the driving shaft rotating arm and the telescopic rod rotating arm are fixedly arranged on the driving shaft; the other end of a driving shaft connecting arm is coupled with a piston rod of the pushing cylinder; the back part of the electric connector is connected with a telescopic rod; the other end of the telescopic rod is coupled with the telescopic rod rotating arm; and after the piston rod of the pushing cylinder extends out and the electric connector is normally coupled, a connection line BC of a connection point B of the telescopic rod and the electric connector and the center C of the driving shaft forms an included angle with a connection line BO of the connection point B of the telescopic rod and the electric connector and the connection point O of the telescopic rod and the telescopic rod rotating arm, and the connection line BC is higher than the connection line BO. The self-locking pushing mechanism can be locked by self and has a good using effect.

Description

technical field [0001] The invention relates to a pushing mechanism for ensuring reliable guiding and positioning and normal connection and separation of an electrical connector in an electrical system, in particular to a self-locking pushing mechanism. Background technique [0002] The electrical connector push mechanism is mainly used to drive and ensure that the electrical connector completes reliable guidance and positioning and normal connection and separation. The push mechanism mainly includes: push cylinder components, support frame components, guide frame components, connecting rod components and other accessories. The support frame and the guide frame are fixed on the hook body, support and install the electrical connector, and make the electrical connector move back and forth along the guide bar on the guide frame. [0003] When the coupler is in the waiting state, the front end of the push cylinder is filled with air, the piston rod is in the retracted state, the...
