The invention discloses a power transfer part assembly structure of an electric fuel pump. Tail ends of two power supply insertion sheets are connected to form a U-shaped structure, magnetic rod limiting bosses are arranged at middle upper parts of the two power supply insertion sheets and face outwards, two magnetic rods are respectively arranged at outer sides of the two power supply magnetic sheets, upper ends of the magnetic rods are in close contact with the limiting bosses, induction coils are wound around the magnetic rods, upper end connectors of the induction coils are connected with the power supply insertion sheets, lower end connectors of the induction coils are connected with carbon brush leads, the carbon brush leads are connected with carbon brushes, a plastic injection shell is arranged outside the power supply insertion sheets and the induction coils, the shell wraps the limiting bosses of the power supply insertion sheets, parts below the limiting bosses, two ends of the magnetic rods, connection points of the induction coils and the power supply insertion sheets and connection points of the induction coils and the carbon brush leads, the shell wraps surfaces, near to the insertion sheets, of the induction coils and surfaces, far away from the insertion sheets, of the induction coils, and the other two surfaces of the induction coils are exposed. By coating a part which is not resistant to corrosion and the connection points in the plastic injection shell, the corrosion of fuel oil to a power transfer part is effectively prevented.
Description
technical field [0001] The invention relates to an electric fuel pump, in particular to an assembly structure of a power transmission part of the electric fuel pump. Background technique [0002] At present, the assembly method of the power plug, inductance coil and carbon brush of the electric fuel pump is as follows: figure 1 and 2 As shown, the power plug 1, the inductance coil 2 and the carbon brush lead wire 5 are connected through the connection piece 9. They are installed on the carbon brush holder, the connection piece is exposed, and the welding points of the connection piece, the inductance coil and the carbon brush lead wire are also exposed. , Soaking in fuel for a long time will easily lead to corrosion of connecting pieces and welding points. After the power transmission part is corroded, it will cause the vehicle to fail to start and malfunction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an...
