Bus input device

Abstract

The invention discloses a bus input device which comprises a shell with an opening at the top. A connecting ring is arranged on one side of the shell, the connecting ring is used for being connected with a controller box body, and a first sealing ring is arranged on the connecting ring; a copper bar hole is formed in the connecting ring; a connector hole is formed in the other side of the shell; a sealing cover is included and is used for sealing the top of the shell; a copper bar input assembly is included and is arranged in the copper bar hole in a penetrating manner, and a second sealing ring is arranged on the copper bar input assembly; and a connector assembly is included and is arranged in the connector hole in a penetrating mode, and the connector assembly is connected with the copper bar input assembly. The device is arranged outside the controller box body and is connected with the controller box body through the connecting ring so that the generated electromagnetic interference is shielded by the controller box body. The controller box body is sealed through the first sealing ring and the second sealing ring so that the controller is prevented from being invaded by external water vapor before final assembly, the sealing of the controller box body is not affected by the installation of the connector, and the controller is prevented from being invaded by the external water vapor during final assembly.

Description

Technical field [0001] The present invention relates to an automotive assembly, and more particularly to a busbar input device. Background technique [0002] With the continuous development of economic and science and technology, electric vehicles are rapidly popularization. In general, electric vehicles include drive motors and batteries, as well, control controls that control drive motors and other electrical devices. The existing controller has a certain deficiencies: the existing controller uses a covering scheme, using the busbar input cavity and controller case integrated solution, this protocol cabinet is in the case of no connection insert The environment is connected, the external water vapor is easy to invade the controller inside, the controller is high, and the controller cabinet structure is complex, the manufacturing difficulty is large, the quality is high; the cost is high due to busbar input cavity and controller case, controller The operation is susceptible to t...

AI Technical Summary

Problems solved by technology

There are certain deficiencies in the existing controllers: most of the existing controllers adopt the cover-opening scheme, and the scheme of integrating the bus input cavity and the controller box is adopted. In this scheme, the controller box is connected with the The environment is connected, and external water vapor easily invades the controller, which requires high storage of the controller, and the structure of the controller box is complex, difficult to manufacture, high in quality, and high in cost; because the bus input cavity is integrated with the controller box, the controller The operation of the bus is susceptible to electromagnetic interference from the bus input, and the EMC performance of the controller is poor and the reliability is poor
