The invention discloses an EMC connector connected with car-mounted equipment. The EMC connector comprises a filter circuit, a terminal, a sealing ring, an insulation cover plate and a conductive shell. The terminal is connected with a power transmission line and used for transmitting power. The filter circuit is electrically connected with the terminal and used for inhibiting electromagnetic interference; the conductive shell is used for sealing the filter circuit, and electrical isolation of the filter circuit and the outside is achieved. The end face of the conductive shell and a car-mounted equipment mounting face are in close contact to achieve grounding. The conductive shell is covered with the insulation cover plate; the sealing ring is arranged between the insulation cover plate and the conductive shell, and waterproof sealing is achieved. According to the EMC connector, an EMC function is achieved in the connector, and on the basis of solving the complete vehicle EMC problem, system arrangement space is saved, and the controller cost is reduced.
Description
technical field [0001] The invention relates to the technical field of automotive electronics, and more specifically, relates to an EMC connector and a motor controller. Background technique [0002] Electromagnetic Compatibility EMC (Electro Magnetic Compatibility) refers to the ability of a device or system to operate in compliance with the requirements in its electromagnetic environment without causing unbearable electromagnetic interference to any equipment in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment during normal operation cannot exceed a certain limit; on the other hand, it means that the equipment has a certain Degree of immunity, that is, electromagnetic susceptibility. [0003] In the field of automotive electronics, connectors have been widely used to realize power transmission. At the same time, a good connector design is also one of the key technologies ...
