Abstract

The invention discloses a method of preventing a terminal of an electric car controller from rotating, and an anti-rotation terminal. The anti-rotation terminal is adopted to serve as a mechanical and electrical connector that is connected to a power output module, a master control circuit board A and an outer heavy current conductor so as to be prevented from rotating along with a fixing screw and becoming loosened when the outer heavy current conductor is connected to dismounted. Through a great improvement upon the terminal, the technical problems that the terminal tends to rotate along with a screw or a bolt when the screw or the bolt is fastened so as to become loosened, a connection fault may occur between the terminal and a circuit board, and the quality of products cannot be guaranteed are solved. The heavy current connection problem about a modularized and standardized structure of a controller is solved, and a foundation is laid for full automation of production and test of the controller. The method and the anti-rotation terminal are suitable for production and manufacturing improvements on electric two-wheel vehicle controllers, electric tricycle controllers and electric automobile controllers.

Description

technical field [0001] The invention relates to a method for preventing the rotation of a terminal of an electric vehicle controller and the used anti-rotation terminal, belonging to the technical field of manufacturing electric vehicle drive motor controllers. Background technique [0002] The electric vehicle drive motor controller (hereinafter referred to as the controller) is the main component of the electric vehicle. The controller includes a heat dissipation and waterproof shell, and a circuit board is installed inside the shell. The main control and power output are installed on the circuit board. functional circuit. The connection between the circuit board in the existing controller shell, the power line, the driving motor and the control elements is mainly connected by external cables or binding posts. At present, when improving the control performance of electric vehicles, generally more attention is paid to the improvement of the electrical functions that can be...
