Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment one:
A kind of motor carbon brush box, comprises box body 1 and feet 2, and wherein: be provided with the interface arrangment connecting carbon brush on described box body 1, described interface arrangment comprises the top groove 3 being arranged at box body 1 top and the card groove 4 being positioned at two side; Described card groove 4 comprises connective slot 5 and card interface 6, and it is that acute angle is arranged that described card interface 6 blocks into the direction in direction and connective slot 5; Described feet 2 is wholely set with box body 1, and the edge of described feet 2 is provided with punch recesses 7; Described card interface 6 opening place is provided with guiding angle 8; The opening place of described top groove 3 is provided with and guides angle 9; Described feet 2 is provided with card and connects boss 10; Described box body 1 is also provided with firm recess 11 in one end that carbon brush is connected into; Described firm recess 11 is circular arc.
