Motor-driven compressor

摘要

A motor-driven compressor includes a shell, an electric motor, a first conductor electrically connected to an external power source, a second conductor electrically connected to the electric motor, a connector connecting the first conductor and the second conductor and a connector case. The connector case has a first case member, a second case member, a first and a second seal members interposed between the first and the second case members, a hole through which the first conductor is inserted and a third seal member sealing between the first conductor and the connector case. A first main seal of the first seal member and a second main seal of the second seal member cooperate to form a cylindrical seal portion for sealing the second conductor that is inserted through the cylindrical seal portion when the first and the second seal members are joined.

主权项

1. A motor-driven compressor, comprising:
a shell provided with a base; an insulator fixed to the base; an electric motor provided in the shell; a first conductor extended through the shell and electrically connected to an external power source, the first conductor inserted through and fixed to the insulator fixed to the base; a second conductor electrically connected to the electric motor; a connector connecting the first conductor and the second conductor; and a connector case made of resin, configured to receive the connector, wherein the connector case includes: a first case member including a first seal surface extending along a periphery of the first case member and including a cylindrical portion formed integrally therewith; a second case member including a second seal surface extending along a periphery of the second case member and facing the first seal surface; a first seal member interposed between the first and second case members and having a first main seal that is joined to the first seal surface; a second seal member interposed between the first and second case members and having a second main seal that is joined to the second seal surface; a hole through which the first conductor is inserted; and a third seal member insert fitted in the cylindrical portion of the first case member in the connector case, so as to directly contact an inner surface of the cylindrical portion, and the third seal member interposed between an outer surface of the insulator and the inner surface of the cylindrical portion so as to form a seal between the insulator and cylindrical portion of the connector case, wherein the first main seal and the second main seal cooperate to form a cylindrical seal portion for sealing the second conductor that is inserted through the cylindrical seal portion when the first and the second seal members are joined, and wherein the cylindrical portion of the first case member of the connector case contacts the base, and wherein the connector case, the insulator, the first seal member, the second seal member and the third seal member are housed in the shell.
