Automotive electric power steering controller assembly for preventing electromagnetic interferences and line to line interferences

Abstract

The invention discloses an automotive electric power steering controller assembly for preventing electromagnetic interferences and line to line interferences. According to the automotive electric power steering controller assembly, a motor power supply plug connector and a sensor signal plug connector are internally injected and molded and are mounted on the front side wall of a protective guard; a vehicle body power supply plug connector and a vehicle body signal plug connector are internally injected and molded and are mounted on the back side wall of the protective guard; the motor power supply plug connector is transversely arranged; the sensor signal plug connector, the vehicle body power supply plug connector and the vehicle body signal plug connector are vertically arranged; the heights of the protective guard from the middle part to the front part are gradually reduced and the height from the middle part to the back part keeps unchanged; a mounting bracket is composed of a horizontal plate, and a vertical plate which is located in the middle of the horizontal plate and is vertically connected with the horizontal plate; a bottom plate and the mounting bracket are fastened together through three bolt and nut assemblies. The automotive electric power steering controller assembly is compact in structure and small in volume; the line to line interferences in an assembly assembling process are effectively avoided and the installation is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of electric power steering control systems, in particular to a vehicle electric power steering controller assembly, which belongs to a mechanical installation structure. Background technique [0002] The controller is an essential part of the electric power steering control system, which consists of a circuit board, a bottom plate, a shield and a connector. The shield and the base plate together form a controller housing, and the circuit board is mounted on the base plate and located in the controller housing. The connectors are installed on the side wall of the shield, the connectors are all upright, and the entire controller housing is a standard square housing. [0003] The main problem of this structure is: due to the different sizes of the connectors, the size of the motor power connector is higher than that of the sensor signal connector, the body power connector and the body signal connector. To mee...
