Controller wire throwing structure integrating EMC module

Abstract

The invention discloses a controller wire throwing structure integrating an EMC module. The controller wire throwing structure comprises a magnetic ring fixing base, wherein a vertical magnetic ring is fixed inside the front end of the magnetic ring fixing base, a filtering module is fixed at the rear end, an insertion structure of a high-voltage busbar is fixed to the front end surface of the magnetic ring fixing base, a through hole penetrating the center of the magnetic ring is formed in the magnetic ring fixing base, the front end of the through hole is communicated with the insertion structure, the rear end of the through hole is communicated with the filtering module, and the high-voltage busbar is in lap joint with the filtering module by means of the insertion structure and the through hole sequentially. A part, connected with a controller shell body, in the wire throwing structure is combined by adopting the specially-made tail cover and a sealing ring, the structure is simple, and the cost is considerable. The installation and disassembly of the busbar are convenient, the maintenance is convenient and the cost is considerable on the premise of ensuring certain sealing performance. The EEMC module and the wire throwing structure are combined together to form the wire throwing structure integrating the EEMC module, thereby further reducing the size of the controller.

Description

Technical field [0001] The present invention relates to the technical field of electromagnetic compatibility, and in particular to a controller wire throwing structure integrated with an EMC module. Background technique [0002] As the power transmission unit of the controller, the high-voltage bus is also a key functional component for the internal and external interface parameters of the OEM and the controller manufacturer. The design of the cable throwing scheme can directly affect the key processes of the whole machine installation and testing-transportation-external interface docking. [0003] EMC, that is, electromagnetic compatibility, includes EMI (electromagnetic interference) and EMS (electromagnetic susceptibility). As far as the controller is concerned, EMI has always existed from the time the vehicle power supply module delivers the voltage to the high-voltage bus, until the controller's internal control unit and drive unit output corresponding electrical signals to t...

AI Technical Summary

Problems solved by technology

The existing EMC structure occupies a certain space of the controller, and the design is more complicated

Considering the cost factor, the existing wire throwing scheme will use the PG head threaded connection method. The disadvantage is that this method is inconvenient to install; under special requirements, the plug-in high-voltage plug-in will be used for internal and external connections. The disadvantage is that the price is more expensive.
