摘要:
An electric compressor provided with an integral inverter, incorporated with a motor and provided in a receiving space surrounded by a compressor housing with a motor drive circuit that includes the inverter. At least some of electric parts including the motor drive circuit are coated at an assembly-completed state with a resin that is charged into the receiving space. The shape of the charged resin is defined in the receiving space by a jig used at the time of resin charging and defining a space to be charged with the resin. In the structure of a resin coating section for such a motor drive circuit, the amount of resin charged is significantly reduced, and the entire compressor is reduced in weight and cost.

The present invention provides a compressor having casings fixed together in a manner allowing the compressor to have a reduced sized as well as reusability.The compressor according to the present invention comprises a plurality of casings (1a, 1b) each having an open end designed to be brought into butt contact, the casings being arranged with the open ends in butt contact with each other, thereby constituting a pressure vessel enclosing a compressing unit; a flange-like projection (3) formed on the outer circumference of the open end of each of the casings, the projections of the casings butted together forming a pair; and a plurality of fixing members (4a to 4c) each in a shape corresponding to a section which would be obtained by dividing the open end of the casing, and having a groove inside, the groove being designed to engage with the paired projections butted together. The open ends of the casings butted together are fixed by the fixing members arranged to surround the casings, each in engagement with the paired projections, and welded to each other.

An electric compressor provided with an integral inverter, incorporated with a motor and provided in a compressor housing with a motor drive circuit that includes the inverter. At least some of electric parts including the motor drive circuit are coated at an assembly-completed state with a resin material at a predetermined thickness by, for example, pouring of a liquid resin and draining of excess resin. In the electric compressor, a resin coating structure of the motor drive circuit is simplified, is easily coated with resin, is reduced in weight by reducing the amount of resin, and is reduced in cost.

An electric compressor provided with an integral inverter, incorporated with a motor and provided in a receiving space surrounded by a compressor housing with a motor drive circuit that includes the inverter. At least some of electric parts including the motor drive circuit are covered by a resin charged into the receiving space, and a part of a region which is in the receiving space and into which the resin can be charged is filled with a light-weight material different from the charged resin. In the structure of the resin covering section for such a motor drive circuit, the amount of resin charged is significantly reduced, and the entire compressor is reduced in weight and cost.

A semiconductor chip is sealed by resin without covering an outer terminal of a semiconductor device having a power transistor. A semiconductor chip having a power transistor is housed within a recess of a metal cap while a drain electrode on a first surface of the semiconductor chip is bonded to a bottom of the recess via a connection material. A gate electrode and a source electrode are formed on a second surface opposite to the first surface of the semiconductor chip, and the gate electrode and the source electrode are bonded with metal plate terminals 6G, 6S via connection materials 5b, 5c. In addition, the semiconductor chip is sealed by a resin sealing body with mounting-surfaces of the metal plate terminals 6G, 6S being exposed. Mounting surfaces of the metal plate terminals 6G, 6S and a third part of the metal cap are bonded to electrodes on a mounting board 10 via connection materials 5e, 5f and 5g.
摘要:
This invention relates to a hermetic compressor used on a refrigerant cycle such as a refrigerator, and discloses a low noise compressor designed to attenuate a resonance sound in a compression chamber and intake pressure pulsing more operatively at a position adjacent to their sources, which intake pressure pulsing occurs at an intake valve port. In the compressor, a resonance space 38 is provided adjacent to the intake valve port 29 that is closer in distance to a noise source. As a result, noise can be reduced more operatively than muffling functions of an intake muffler 31 do. In addition, although acoustic characteristics of the intake muffler 31 amplify noises having specific frequencies, such noises can be attenuated before being amplified.
