Summary of the Invention The problem to be solved by the invention is to provide a starting end cover assembly of a four-pole motor, which is simple in structure and convenient and fast to mount, and can save the manufacturing material of leading-out wires, reduce the manufacturing cost and simultaneously enable the overall layout of an end cover to be easier. In order to solve the technical problem, the invention adopts the following technical scheme: the starting end cover assembly of the four-pole motor comprises a cover plate, wherein a brush frame plate is arranged on the cover plate, an electric brush I, an electric brush II, an electric brush III and an electric brush IV are uniformly distributed on the brush frame plate, the electric brush I and the electric brush III are oppositely arranged, the electric brush II and the electric brush IV are oppositely arranged, and the starting end cover assembly of the four-pole motor is characterized in that an electrode connector connected with an external circuit is arranged on the brush frame plate, two leading-out wires are respectively connected on the electric brush I and the electric brush III for connecting onto the electrode connector, a conductive connection structure which is used as the other electrode connecting end for connecting with the external circuit is further arranged on the brush frame plate, and the two leading-out wires are respectively connected on the electric brush II and the electric brush IV for connecting onto the conductive connection structure. Further, the conductive connection structure comprises the cover plate, a metal connecting sheet I and a metal connecting sheet II, wherein the metal connecting sheet 1 I and the metal connecting sheet II are arranged on the brush frame plate and in contact with the cover plate, the cover plate is a metal plate, the metal connecting sheet I is arranged on the side edge of the electric brush II, the metal connecting sheet II is arranged on the side edge of the electric brush IV, the leading-out wire on the electric brush II is connected onto the metal connecting sheet I, the leading-out wire on the electric brush IV is connected onto the metal connecting sheet II, and a conducting wire connected with the external circuit is connected on the cover plate. The leading-out wires are shortened and the material consumption is reduced. Further, the metal connecting sheet I and the metal connecting sheet II are oppositely arranged on the edges of the brush frame plate. The connection between the metal connecting sheets and the cover plate is more direct, and the conductive effect is better. Further, wire connection clips are respectively arranged on the metal connecting sheet I and the metal connecting sheet II. The connection and the fixation of the leading-out wires are convenient. Further, the cover plate is riveted and fixed with the brush frame plate. A riveting machine is used for fixing the cover plate and the brush frame plate, thereby being convenient and fast. Further, a placing groove for embedding the electric brush I, the electric brush II, the electric brush III and the electric brush IV is arranged on the brush frame plate. The electric brushes are convenient to place and take out. After the technical scheme is adopted, the invention has the following advantages: the conductive cover plate is taken as one electrode connecting end, the leading-out wires are shortened, and the material waste is reduced, thereby not only reducing the production cost, but also being convenient for spatial layout, enabling the overall structure to be simpler and clearer and being convenient for mounting and checking.
