POWER MODULE OF WELDING-FREE TERMINAL

摘要

The present invention relates to a power module of a welding-free terminal. The terminal comprises a connection part with an elastic upper part and a main body part with a shaft shoulder, and the bottom surface of the terminal is toothed. Plugholes for guiding the main body parts of various terminals are provided on a housing, and sunken platforms corresponding to the shaft shoulders of the terminals are arranged at the tops of the plugholes; the terminals are arranged in the respective corresponding plugholes of the housing; the shaft shoulders of the terminals are arranged on the sunken platforms; an elastic insulating pressure pad is arranged at the upper part of the housing; a cover plate is mounted onto the housing by a clamped connection and is in a pressure connection on the elastic insulating pressure pad; the terminals penetrate through respective corresponding terminal holes on the elastic insulating pressure pad and respective corresponding terminal holes on the cover plate; the elastic insulating pressure pad presses on the shaft shoulders of the terminals; the toothed bottom surfaces at the bottom of the terminals are in a pressure connection on a cermet coated substrate; and the connection parts of the terminals are elastically connected with terminal holes of a driver circuit board. The present invention is reasonable in structure; and the terminals do not need to be welded and can be reliably connected to a cermet coated substrate after being assembled, and the manufacturability is good.
