[0030] Referring to Figures 1-2 As shown, the following optimization is carried out for each component, the negative pole connector 3 is a hoop piece, so that the negative pole connector 3 can be stably combined with the negative pole of the battery pack, and simultaneously, the car load connector 7 is a round table-shaped plug connector, the positive pole connector 1 is an elliptical column-shaped plug connector, so that the wiring of the car load can be quickly combined with the car load connector 7 through plug-in connection, and the positive pole wiring of the battery pack can also be quickly combined with the positive pole connector 1 through plug-in connection, and through plug-in connection, repeated combination and disassembly operations are also facilitated. Further, the parking load connector 5 is a bolt piece with a nut, so that the wiring of the parking load can be fixed by winding around the periphery of the parking load connector 5 and tightening the nut, and stable fixation of the parking load wiring is facilitated.

[0031] Referring to Figures 1-4As shown, the conductive copper sheet one 2 is riveted to the base body 6 to facilitate the stable combination of the conductive copper sheet one 2 on the top surface of the base body 6 and the stable electrical connection with the base body 6. At the same time, the conductive copper sheet one 2 and the conductive copper sheet two 9 are electrically connected in series with the PCB control panel 8 to facilitate the stable electrical connection of the conductive copper sheet one 2 and the conductive copper sheet two 9. Further, the PCB control panel 8 is combined and installed between the top surfaces of the conductive copper sheet one 2 and the conductive copper sheet two 9 to facilitate the separation of the PCB control panel 8 from the base body 6 by means of the conductive copper sheet one 2 and the conductive copper sheet two 9. As to the plastic shell 4 and the plastic sealing member 10, the plastic shell 4 is an insulating plastic shell, the plastic sealing member 10 is an insulating rubber pad, and the inner and outer peripheries of the plastic sealing member 10 respectively insulate the parking load connector 5 and the base body 6.
