20090010786 | Electrically-Driven Compressor - An electrically-driven compressor including a housing, an electric motor, a compression mechanism, a cover member, a motor drive circuit, and a sealing member is disclosed. The electric motor is accommodated in the housing. The compression mechanism is accommodated in the housing and operated by the electric motor. The cover member is attached to the housing. The housing and the cover member form an accommodation portion including an accommodation space therein. The motor drive circuit is accommodated in the accommodation space and drives the electric motor. The sealing member is arranged between the housing and the cover member to seal the accommodation space. The sealing member includes an elastic seal portion that comes into close contact with the housing and the cover member. A core sustains the shape of the seal portion in conformance with the circumferential edge of the accommodation space. The core is formed so that at least a circumferential edge part of the core is in conformance with the circumferential edge of the accommodation space. The seal portion is formed integrally with the circumferential edge part of the shape sustaining member by depositing rubber material thereon. | 01-08-2009 |
20130202461 | MOTOR-DRIVEN COMPRESSOR - A motor-driven compressor includes a connector-receiving portion provided on the outer surface of a housing. A wiring connection portion is provided in the connector-receiving portion and supplies electricity from an external power source to a motor drive circuit. The wiring connection portion includes a first terminal, a second terminal, and a metal plate for connecting the first and the second terminals to each other. The first and the second terminals have a first end-connection portion and a second end-connection portion, respectively. The second end-connection portion of the first terminal is electrically connected to the external power source, and the second end-connection portion of the second terminal is electrically connected to the motor drive circuit. | 08-08-2013 |
20130202463 | MOTOR-DRIVEN COMPRESSOR - A motor-driven compressor includes a connector receiving portion provided on the outer surface of a housing. A wiring connection portion is provided in the connector receiving portion and supplies electricity from an external power source to a motor drive circuit. An insulating member provided inside the connector receiving portion insulates the wiring connection portion and the connector receiving portion from each other. An electrical wire is arranged between the inner surface of the connector receiving portion and the insulating member. The electric wire is used for a purpose other than supply of electricity to the motor drive circuit. A recess is formed in at least one of the inner surface of the connector receiving portion and the outer surface of the insulating member. The recess forms a wiring space, in which the electrical wire is arranged, between the connector receiving portion and the insulating member. | 08-08-2013 |
20130330217 | MOTOR-DRIVEN COMPRESSOR - A motor-driven compressor includes a compression unit, an electric motor, a housing that includes an accommodating chamber and a wiring connection port, a motor driving circuit that includes a substrate arranged in the accommodating chamber, wiring electrically connected to the substrate and extending out of the housing through the wiring connection port, and a resin sealing member fitted to the wiring connection port. The wiring includes a primary conductor, which has a first end connected to the substrate and a second end, and a secondary conductor, which is connected to the second end of the primary conductor and arranged outside the housing. The secondary conductor includes a wire portion and a sheath that is made of an insulating material and covers the wire portion. The sealing member covers the sheath and a junction between the primary conductor and the secondary conductor. | 12-12-2013 |
20140377094 | MOTOR-DRIVEN COMPRESSOR - A motor-driven compressor that includes a compression unit adapted to compress refrigerant, an electric motor adapted to drive the compression unit, and a housing that accommodates the compression unit and the electric motor and includes a coupling member. A motor driving circuit drives the electric motor. The motor driving circuit includes a circuit board and a capacitor, which is electrically connected to the circuit board. A capacitor holder holds the capacitor and is coupled to the coupling member. One of the capacitor holder and the coupling member includes a projection, and the other one of the capacitor holder and the coupling member includes an engagement portion that engages with the projection. Engagement between the projection and the engagement portion positions the capacitor holder relative to the coupling member. | 12-25-2014 |
20140377095 | MOTOR-DRIVEN COMPRESSOR - A motor-driven compressor includes a motor driving circuit including a capacitor electrically connected through a lead to a circuit board, and a capacitor holder that is made of a plastic and holds the capacitor. The capacitor holder includes a side wall, which covers a side surface of the capacitor. The lead protrudes from the side surface. The side wall includes a through-hole, which opens through each of a first end surface of the side wall facing the circuit board and a second end surface of the side wall opposite to the circuit board and guides the lead to a portion of the circuit board to which the lead is to be connected. The side wall includes a wall surface facing the capacitor. The wall surface includes a slit, which is continuous with the through-hole and opens opposite to the circuit board. | 12-25-2014 |
20140377096 | MOTOR-DRIVEN COMPRESSOR - A motor-driven compressor includes a motor driving circuit, which includes a capacitor electrically connected to a circuit board, and a capacitor holder, which holds the capacitor. The capacitor holder includes a side wall body, which covers a side surface of the capacitor, a first retainer, which extends from the side wall body to the circuit board and engages with a first end surface of the capacitor, and a second retainer, which extends from the side wall body in a direction away from the circuit board and holds the second end surface of the capacitor. The length of the second retainer in the extending direction of the second retainer is greater than the length of the first retainer in the extending direction of the first retainer. | 12-25-2014 |
