Apparatus 1 for interconnecting integrated circuit devices 2, extending in a row 16, column 17 and stack 19 with circuit boards 3 assembled to corresponding circuit devices 2, and jumper circuit boards 4 assembled to said circuit boards 3 with arrays of contacts 6, 7, and 15 interconnecting to the boards with the assembly forming a three-dimensional interconnection of devices.

Electrical interconnection of circuit devices

An electrical pin header connector (2) comprises an insulating housing (4) having an interface surface (6) and an opposite mating face (8), between which extends a grid array of electrical contact element receiving cavities (10). In each cavity (10) is an electrical contact element (12) having an elongate contact spring (14) with a contact nose (16) projecting from the interface surface (6) for engagement by a respective contact pad (44) of a grid array of contact pads (44) on an interface surface (42) of a mother printed circuit board (40). Each contact element (12) has a contact pin (26) projecting from the mating face (8) of the housing (4). The contact springs (14) are angled by 45.degree. with respect to X and Y axes of the grid array of cavities (10), for maximum contact density. The contact pin (26) of each contact element (12) has been twisted through 45.degree. with respect to the contact spring (14) thereof so that opposed flat contact surfaces (C) of the contact pin (26) are parallel to one axis of the grid array of cavities (10) and are at right angles to the other. This orientation of the contact surfaces (C) enables the pin header connector (2) to be mated with a mating connector (32) having twin contact beam terminals (54) so that each contact surface (60) of each pair of twin beams (58) engages a respective contact surface (C) of a respective contact pin (26).

A connector system for distributing power to daughter cards in a card cage includes a power connector for each card mounted on framework of the card cage. Each power connector has individual terminals connected to power conductors connected to a power supply and at least one terminal connected to a return path conductor. Each power connector includes a channel along which an active edge of the card is inserted and moved longitudinally from an open end, opposed from another channel aligned therewith, until the daughter card is fully inserted into the card cage, and signal transmission connectors along the back card edge mate with connectors of the backplane of the card cage. The daughter card is then locked in position; its power connector is then actuated, camming contact sections of its terminals into electrical engagement with contacts along the active edge of the daughter card. Each daughter card is thus powered and correspondingly disconnectable independently of the other daughter cards. An interference arrangement prevents the power connector from being actuated unless the card is locked in position, and prevents unlocking and removal of the card unless the power connector is deactuated. A dielectric rail along the card's active edge is shaped to fit the channel of the power connector and protect the active edge and contact sections therealong exposed in recesses of the rail. A daughter card may have two active edges, each with a rail insertable into channels of a pair of opposed power connectors.

Power connector system for daughter cards in card cages

An electrical connector housing for flat cable comprising first and second members movable between mutually adjacent and remote positions corresponding to closed and open conditions of the housing respectively. Latching means comprise a latch bar and a release bar supported for deflection adjacent an end of one member and extending spaced apart in side-by-side relation interconnected by a plurality of transverse struts to defining an eye. A catch means on the other member is receivable in the eye in latching engagement with the latching bar in the closed condition of the connector housing, movement of the release bar in the direction of the latch bar deflecting the latch bar, thereby to disengage the catch means from the latch bar. The latch bar and release bar are resiliently flexible and the latch bar is joined at respective opposite ends of a slot to the one member by relatively rigid webs, deflection of the release bar towards the one member flexing the latch bar to disengage the catch member from the latch bar. The latch bar carries catch portions, the catch portions adjacent lateral ends of the bar being located rearwardly, in the direction of deflection, of catch portions adjacent central portions of the bar.
