Cable entry seal for motor-driven compressor

摘要

A motor-driven compressor (10) includes a shell (14), an electric motor (M) provided in the shell, a first conductor (35) extended through the shell and electrically connected to an external power source (29), a second conductor (39) electrically connected to the electric motor, a connector (40) connecting the first conductor and the second conductor and a connector case (41) receiving the connector. The connector case (41) has a first case member (42) including a first seal surface extending along the periphery of the first case member, a second case member (43) including a second seal surface extending along the 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 (18) 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 (49) through which the first conductor is inserted and a third seal member (46) provided in the connector case and sealing between the first conductor and the connector case. 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.
