Abstract

A motor compressor comprising: a casing having a fitting surface formed on an outer peripheral surface thereof and a plurality of insertion holes extending through the casing on the fitting surface; a compression mechanism accommodated in the casing ; an electric motor housed in the housing for driving the compression mechanism; a plurality of wiring pins that transmit current to the electric motor; a wiring base fastened to the housing by bolts for fixing to the mounting surface, the wiring the base body is formed with a plurality of holes, the wiring pin is inserted into each hole of the wiring base body and is fixedly supported on the wiring base body so as to be insulated and airtight, the insertion holes corresponding to the holes; and provided on the fitting surface and the wiring base, and each wiring pin is inserted into the corresponding insertion hole of the mounting surface.

Description

technical field [0001] The present invention relates to a motor compressor including a compression mechanism and an electric motor as a driving source of the compression mechanism in a casing of the motor compressor. Background technique [0002] Such motor compressors have a plurality of terminal pins fixed to and extending through the housing of the motor to supply electrical current to the electric motor housed within the housing. [0003] A structure for fixing terminal pins to the housing is described in Unexamined Japanese Patent No. 2002-155862, in which a plurality of through holes are formed in the housing, and each terminal pin passes through an O-ring and The bushing, acting as an insulator, is thus supported in the housing and secured by a circular clip engaging in the through hole. [0004] Another fixing structure is described in Unexamined Japanese Patent No. 2002-369439, in which the mounting flange of the terminal has a plurality of terminal pins connected ...
