A mistake-proofing coding structure for motor wiring terminals

Abstract

This utility model discloses a motor terminal block anti-misinsertion coding structure, relating to the field of terminal block technology. It includes a first terminal and a second terminal. The top of the first terminal is connected to a socket, and the socket has a socket hole in the middle. A first anti-misinsertion slot and a second anti-misinsertion slot are respectively formed on both sides of the socket hole. Fixing components are installed on the inner walls of both the first and second anti-misinsertion slots. One of the fixing components includes a fixing seat installed on the inner wall of the first anti-misinsertion slot, and a fixing post is fixedly connected to the top center of the fixing seat. In this utility model, the rotational motion is converted into axial thrust through the helical pair characteristics of the bidirectional screw, allowing the abutment claw to press against the inner wall of the anti-misinsertion block. Unlike a spring that only provides instantaneous elasticity in the initial stage, the thread engagement characteristics ensure stable clamping force throughout the entire service life, reducing the possibility of loosening.
