Abstract:
An electric compressor includes a compression mechanism, an electric motor for driving the compression mechanism, and a drive circuit for controlling the electric motor. The drive circuit includes an external connector made of an insulating material. The external connector has a connecting terminal that is constructed to be electrically connected to an external power source. The drive circuit further includes a circuit board electrically connected to the connecting terminal and a filter element electrically connected to the circuit board. The drive circuit is accommodated in a metal housing. The filter element is integrally formed with the external connector such that contact of the filter element with the housing is prevented.
Abstract:
A structure for connecting a circuit board and an external connector includes a lead and a stress dampening unit. The lead electrically connects the circuit board and the external connector. The external connector is fitted to and removed from the lead. The stress dampening unit dampens stress applied to the circuit board by the lead when the external connector is fitted to and removed from the lead.
Abstract:
A motor-driven compressor includes a housing having at one end thereof an accommodation space, an electric motor, a motor driver circuit provided in the accommodation space and having a circuit board, a connector having a bus bar electrically connected to the circuit board, and a cylindrical portion located at the one end of the housing and extending toward the direction close to the electric motor. The housing has a mounting hole communicating with the accommodation space and the interior of the cylindrical portion. The bus bar has a bent shape having opposite ends extended toward the direction close to the electric motor. The connector is disposed in the mounting hole with one end of the bus bar inserted in the cylindrical portion and the other end of the bus bar inserted in the accommodation space. The mounting hole is closed up by a cover with a seal member provided therebetween.
Abstract:
A motor-driven compressor includes a compression mechanism, an electric motor, a compressor housing, a conductive member, a terminal base, an insulating member, a connection terminal, a wire assembly, a terminal housing, first and second holes formed through the terminal housing and first and second seal members. The conductive member extends from the inside to the outside of the compressor housing and connected electrically to the connection terminal at a terminal connection. The wire assembly has a core wire connecting electrically between the connecting terminal and the electric motor, and an insulator covering the core wire. The terminal housing disposed in the compressor housing covers the terminal connection. The wire assembly has an insulating tube covering the insulator, wherein both ends of the insulating tube are opened for communicating with the inside and the outside of the terminal housing through a clearance formed between the insulating tube and the insulator.
Abstract:
An electric compressor includes an inverter cover. The inverter cover has a metal plate that is arranged to cover an inverter (a circuit board). The metal plate has bolt insertion holes, through which metal bolts for fixing the inverter cover to a suction housing are passed. The head of each bolt contacts a flange portion, which is the periphery of the corresponding bolt insertion hole. The inverter cover is formed of plastic by being molded in a mold, using the metal plate as a core.
Abstract:
A motor-driven compressor includes a connector to which a first and second conductors are connected, and a connector case receiving the connector. The connector case includes a first case member and a second case member. A seal member is provided between the first and second case members. The first case member has a first sealing surface extending along the periphery of the first case member. The second case member has a second sealing surface extending along the periphery of the second case member and facing the first sealing surface. The seal member includes a main seal portion for sealing between the first sealing surface and the second sealing surface. The main seal portion has a first peripheral seal portion for sealing the periphery of the first conductor inserted therethrough and has a second peripheral seal portion for sealing the periphery of the second conductor inserted therethrough.
Abstract:
An electric part fixing structure for a motor-driven compressor includes an electric part having a plurality of leads and a guide member for positioning the leads. The guide member is made of a plastic and has a guide hole through which the lead is passed.
Abstract:
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.
Abstract:
A stator core includes an insertion hole that has an opening in an outer peripheral surface of the stator core and a bent portion in the stator core. A cluster block includes an insertion piece, which is inserted into the insertion hole via the cornered portion. The cluster block is attached to the stator core by engaging the insertion piece with the insertion hole.
Abstract:
A fixing structure for an electrical component includes a heat removing member for removing heat from the electrical component. The heat removing member has a receiving portion for receiving the electrical component. The fixing structure for an electrical component further includes a separation member that is coupled to the electrical component to separate the electrical component from the heat removing member. The separation member is coupled to the heat removing member. The fixing structure for an electrical component includes a soft material member that is accommodated in the receiving portion to contact the receiving portion and the electrical component. Heat of the electrical component is transmitted to the heat removing member via the soft material member.
