PURPOSE: To improve operability, decrease the processing stages, and thereby reduce a cost by installing a connector which electrically connects an electrical equipments to an external electric wiring on an outer peripheral part of the electrical equipment connected to a glass terminal of a sealed vessel.

CONSTITUTION: When an electrical equipment is installed on a compressor, first of all, an integral electrical equipment 10 is previously assembled by wiringly connecting a base 1 to an internal connector 2, housing and fixing the base 1 into a cover 4, fixing the internal connector 2 to a fixation groove 5. The integral electrical equipment 10 is installed and fixed onto a glass terminal 24 of a sealed vessel 21, while an external connector 3 to which an external electric wiring 18 is previously connected is connected to the internal connector 2. It is thus unnecessary to previously install the external electric wiring 28 on a terminal of the base 1, thereby it is possible to reduce a cost by improving the operability and decreasing the processing stages.
