The purpose of this utility model is achieved in that
Direct current machine composite type carbon brush barrier assembly, it is characterized in that, it comprises carbon brush cover and both sides plastic jacket thereof, the end face at carbon brush for electric machine place made and is installed in by described carbon brush cover by insulating material, the carbon brush cover is the tabular body of book, it comprises the book base plate, a plurality of securing members are isolated protruding cover and preceding, back carbon brush body is isolated protruding cover, before, back carbon brush body isolate protruding be set on the book base plate before, back two ends, a plurality of securing members are isolated before protruding cover branch is located at, back carbon brush body is isolated the both sides of protruding cover, preceding, back carbon brush is isolated on the book base plate between the protruding cover and is also had the circular mounting through hole, and before described, back carbon brush body is isolated on the front/rear end of protruding cover and is had through hole; Described each plastic jacket is divided into plastic bottom board, side plate is isolated in both sides sealing cage and insulation, the both sides plastic jacket be separately positioned on carbon brush cover before, back two ends, and before the both sides sealing cage seals the carbon brush cover respectively, back carbon brush is isolated the securing member on protruding cover both sides and is isolated protruding cover, so that the metal fastenings that securing member is isolated in the protruding cover seals fully, insulation isolation side plate then is buckled in carbon brush and puts, motor pinout connector and metal power connecting sheet are sealed by plastic jacket, simultaneously metal power connecting sheet and metal shell are separated, increase insulation effect, can prevent carbon brush wearing and tearing aggravation effectively, carbon dust gathers increase, and causes the direct current machine composite type carbon brush barrier assembly of short circuit.
The purpose of this utility model can also adopt following technical measures to solve:
As scheme more specifically, the insulation of described plastic jacket isolate side plate central authorities be provided with the carbon brush cover cooperates, the fastening hook to prevent that plastic jacket from coming off, help improving plastic jacket and the carbon brush firmness between overlapping.
Described plastic jacket has certain camber, to adapt to the shape of carbon brush cover book base plate.
The beneficial effects of the utility model are:
(1) direct current machine of the present utility model composite type carbon brush barrier assembly, by of the overall co-ordination of carbon brush cover with plastic jacket, so that the metal fastenings that securing member is isolated in the protruding cover seals fully, and plastic jacket is with motor pinout connector and the sealing of metal power connecting sheet, simultaneously metal power connecting sheet and metal shell are separated, increase insulation effect, can prevent carbon brush wearing and tearing aggravation effectively, carbon dust gathers increase, and causes the deficiency of short circuit; Have, simple and reasonable for structure between carbon brush cover and the plastic jacket installed simple and easy, firm again; And the syndeton between them is compacter, and volume is little.
