Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
