Claims

[Scope of utility model registration request]

An electric element and a compression element are housed in a sealed container, and an interphase insulator insulates the phases of the coil end of the stator of this electric element, and an overload that is fixed to the surface of the coil end of the stator with a tying thread. In a hermetic electric compressor equipped with a protector, a protruding part made by bending interphase insulating paper to protrude from the coil end surface is provided between the overload protector and the coil end surface of the stator. Features of hermetic electric compressor.
