CIRCUIT BOARD ASSEMBLY STRUCTURE OF PUMP UNIT, PUMP UNIT, AND VEHICLE

WIPO Patent Application WO/2022/048370

A1

The present application provides a circuit board assembly structure of a pump unit, the pump unit, and a vehicle. The circuit board assembly structure comprises: a circuit board; at least one electric plug-in provided on the circuit board and electrically connected to the circuit board, the electric plug-in comprising an insertion hole and an elastic conductive portion; an end cover comprising a first connecting portion used for connecting a housing of the pump unit; and a plug connector comprising a pin and a sleeve sleeved outside the pin. The sleeve and the circuit board are located on both sides of the end cover, and the pin passes through the end cover to be engaged with the insertion hole and in contact with the elastic conductive portion. In the present application, the plug connection between the pin of the plug connector and the circuit board is achieved by means of the electric plug-in, thereby achieving welding-free fixation, and the operating method is easier. Moreover, because the elastic conductive portion of the electric plug-in can be elastically deformed, resistance borne when the pin is inserted into the insertion hole can be remarkably reduced, so that the operation intensity generated when the pin is inserted into the circuit board is remarkably reduced, and the assembly difficulty of the pin and the circuit board is greatly reduced.
