Abstract

The utility model provides a motor output terminal group comprising a motor-side terminal group, an output-side terminal group, and a conduction connecting piece. The conduction connecting piece comprises a plurality of mutually-insulated metallic conductive slices used for conducting motor-side terminals and output-side terminals in corresponding conduction relations. The metallic conductive slices are equipped with self-locking portions corresponding to the positions of the motor-side terminals and the output-side terminals to be conducted with the metallic conductive slices. The motor-side terminals and the output-side terminals pass through corresponding self-locking portions to be tightly locked. The motor-side terminal group conducts the motor-side terminals and the output-side terminals with the metallic conductive slices. The metallic conductive slices tightly lock the motor-side terminals and the output-side terminals with the self-locking portions. Therefore, in an assembling process, the motor-side terminals and the output-side terminals are not required to be soldered. As a result, short circuit between terminals caused by soldering beads in a soldering process, insufficient soldering, and soldering omitting can be prevented, and the quality of a motor can be effectively enhanced.
