Abstract:
A method of reducing the height of a sealed compressor incorporates the use of a non-cylindrical portion of the stator windings on the compressor motor. A non-cylindrical portion provides a space between the sealed housing and the windings that can accommodate an additional component. In one embodiment, the additional component is the electrical connection, and in another embodiment, the additional component is an oil heater. Typically, these components were mounted axially beyond the extent of the motor stator, and thus required additional space. The present invention thus allows a smaller height compressor profile.
Abstract:
A low-profile in-shaft connector including a female connector (82) and a male connector (90) for electrically connecting a power source to the electrical windings of a motor for rotating a magnetic disc storage system. The female connector (82) includes a sleeve extension (50) that extends down and around the three pins (72, 74, 76) of the female connector and engages the outward sides of the pins in order to prevent lateral deflection of the pins and thereby increase the spring biasing force of the electrical connection between the male and female connector components.
Abstract:
An electric compressor has improved ability to connect an end of a stator winding with fastening terminals so that electrical connection can be established between the stator winding and the sealed terminal. The electric compressor includes lug terminal strips connected electrically to ends of lead wires from the stator winding each covered with an insulating tube, and fastening terminals connected through the lug terminal strips to the sealed terminal for supplying power to the electric elements. The lug terminal strips are manufactured by press molding and each includes a pair of conductor pressing portions, a cylindrical portion formed on one side of the conductor pressing portions, and a pair of insulating film fixing portions formed on the other side of the conductor pressing portions so that the fastening terminal can be connected to the cylindrical portion by pressing the conductor pressing portions onto the stator winding and fixing the insulating film fixing portions to the insulating tube by pressure welding.
Abstract:
A hermetic terminal for carrying electric current into the housing of a hermetic compressor, including a cup-shaped metallic body member having a plurality of metallic conductor pins extending therethrough which are electrically insulated from the body member by hermetic glass seals. The body member includes a closed end having an inwardly facing contoured end surface, to which a correspondingly contoured contacting surface of an electrically insulating cap member is secured by means of a uniform layer of electrically insulating bonding material therebetween. The pins extend through passages in the cap member, whereby the cap member defines an oversurface distance between the pins and the body member. A portion of the oversurface distance is protected from contaminants which the compressor housing by means of an annular gap between the outer periphery of the cap member and the sidewall of the body member, and by respective annular gaps between the pins and corresponding passages in the cap member.
Abstract:
A terminal block includes: a base plate; a first fixing portion arranged on the base plate, to which an end portion of a first bus bar is fixed; a first wall portion erected on the base plate and forming an extension path of the first bus bar; a second fixing portion arranged on the base plate side by side with the first fixing portion, to which an end portion of a second bus bar is fixed; and a second wall portion erected on the base plate and forming an extension path of the second bus bar. The first wall portion has a first interference region preventing arrangement of the second bus bar to the first fixing portion, and the second wall portion has a second interference region preventing arrangement of the first bus bar to the second fixing portion.
Abstract:
A coupling method of coupling a flexible flat cable to a connector by a robot, includes a preparation step of preparing the connector having an insertion hole into which the flat cable is inserted and a seat having an introduction surface placed at a front side of the insertion hole and continuously coupled to the insertion hole, a first moving step of gripping the flat cable and moving the flat cable to a position facing the seat; and a pressing step of bringing the flat cable into contact with the introduction surface in a posture inclined relative to the seat with an end of the flat cable facing the insertion hole side and pressing the flat cable against the introduction surface, and moving the end toward the connector side.
Abstract:
An electric motor including a housing, a busbar, an end plate, and a contact adapter. The housing may include a shield that may define an aperture. The busbar may extend from a stator towards the aperture and the busbar may be disposed within the housing. The contact adapter may include a base member, a contact member, and a protrusion. The contact member may extend from the base member and contact the busbar. The protrusion may extend from the base member and the protrusion may be sandwiched between the shield and the end plate.
Abstract:
A connector portion includes a first system connector that holds a first system terminal and a second system connector that holds a second system terminal. An insertion/removal direction of the first system connector and the second system connector are the same as an axial direction of a motor. The first system connector and the second system connector are arranged close to each other such that the long length directions of the frontages of the connectors are aligned, and that the interval between the connectors is smaller than the width in the short length direction of both connectors. The connectors have protrusions that project in a direction orthogonal to the direction in which the connectors are arranged.
Abstract:
A motor device for an electric bicycle may include an electric motor, a first connector unit, and/or a second connector unit. The electric motor may include an axis of rotation. The first connector unit may include a first motor connector and a first connecting part. The first connecting part may surround the first motor connector regionally and/or outwardly. The first connector unit may be mounted on the electric motor and may be electrically conductively connected to the electric motor via the first motor connector. The second connector unit may include a second motor connector and a second connecting part. An electrical conductive connection may be established and released directly between the first motor connector and the second motor connector.
