Abstract
A structure for mounting a motor protector substantially as a thermally responsive switch in an enclosed electric compressor including an electric motor and a compressing means provided in a closed housing. The structure includes a terminal support provided air-tightly through an upper wall of the compressor housing, a plurality of conductive pins for connecting an external power-supply circuit to the motor, the conductive pins projecting inside and outside the terminal support. One of the inner conductive pins is conductively connected to a terminal pin provided in the motor protector or to an equivalent thereof. Thus, the motor protector is disposed and held within the compressor housing so that heat is exchanged between the motor protector and a coolant gas. A motor winding is connected to the other terminals and the other conductive pins provided in the terminal support.
