Abstract: A disk drive interposer may include a component board assembly, and an interconnect board. The component board assembly may have a plurality of electrical components electrically connected by a first set of electrically conductive traces. The interconnect board may have a first plurality of electrically-conductive pads disposed along a disk drive mating edge of the interconnect board and a second plurality of electrically-conductive pads disposed along a backplane mating edge of the interconnect board. The first plurality of pads may be electrically connected to the second plurality of pads by a second set of electrically conductive traces. A mezzanine connector may electrically connect the first set of traces and the second set of traces. Such an interposer may physically and electrically mimic a disk drive from the frame of reference of a backplane, and physically and electrically mimic a backplane from the frame of reference of a disk drive.

Abstract: An electrical connector for a substrate including a housing having a base, an elongated channel and a plurality of cantilever contacts mounted in the base extending into the channel, and a member operatively mounted in the channel having a base including an aperture receiving each contact mounted in the base of the insulating housing. Inter-engaging latch arms on the housing and member provide for zero insertion force loading of the substrate in the member in a loading position. A cam surface in each aperture cams each contact into engagement with a conductive pad on the substrate and provides a wiped, graduated force electrical connection when the substrate and member are operatively engaged in the housing in a loaded position and the substrate, member and housing are secured by the inter-engaging latch arms on the member and housing.

Abstract: An electrical connector for a flat multi-conductor transmission cable includes a cable terminating face, a parapet having a plurality of V-shaped grooves and a scalloped top extending from the face, a bus strip engageable with the face, and a cover. Also, a method for terminating the cable includes severing an insulated sheath of the cable intermediate its end, sliding the severed insulated end along a length of the conductors to expose the shield and signal conductors, severing the signal conductors, folding the insulated end of the transmission cable back along its length over a bus strip, and engaging the shield conductors with the bus and the signal conductors with electrical terminals on the face of the connector.

Abstract: An electrical connector for forming a high amperage connection with a male pin includes a number of beams surrounding the pin and a collar surrounding the beams. The end of the pin is inserted into the connector and moved past outer contacts on the beams and engages inner contacts on the beams to force the inner contacts radially apart and rock the beams about the inner surface of the collar to force the outer contacts against the pin. Alternate inner contacts are axially spaced to reduce the insertion force.

Abstract: A flat conductor cable connector includes a base for receiving a conductor including a pair of apertures in the base and a pair of upstanding insulation-rupturing lances spaced inwardly of the apertures in the base, and an arm hingedly connected with the base including a pair of lances, each lance in alignment with one of the apertures in the first layer of the base.

Abstract: A zero force edge connector block includes a plurality of terminals for engaging pads on a circuit board, an elongate cam bar extending along the terminals, and a drive for shifting the cam bar along the terminals so that the cam bar engages ramp surfaces in the block and is raised diagonally to engage the terminals and move the terminals to a retracted position. After the board has been positioned in the block, the cam bar is moved back to its initial position, thereby freeing the terminals to engage contact pads on the board.
