Abstract: An electrical connector comprises a generally cylindrical tube member (10) having a tube wall (12) and an electrically conductive body (22) having a plurality of louvers (24) in a generally tubular array. The body and the tube member are nested one within the other, with the louvers having respective sides (28) projecting away from the tube wall for engagement with a complementary connector. The body and the tube member are secured against relative axial movement in at least one direction by at least one extruded projection (40) of the tube wall.

Abstract: A tappable conductive bus bar (11, 11') has a longitudinal slotted recess (17, 19) receiving at least one louvered spring strip (22, 23). At least one tab (26) is received through a gap (21) in the bus bar (11) to engage the louvered spring strip (22, 23). The bus bar (11) supplies current, with minimum wiring and parts, to one or more tabs (26), and the spacing between adjacent tabs (26) is not critical. Thus, the bus bar (11) is completely tappable.

Abstract: Terminals having rectangular post sections of very small dimension are secured in housing passageways of an electrical connector, which passageways are molded using core pins larger in dimension than said very small dimensioned terminal post sections, so that the oversized core pins are robust and endure repeated molding cycles. End sections of the core pins have the very small dimension of the terminal post sections and the passageways have constricted end sections which precisely locate the terminal post section along the connector mating face. An increased terminal width at the insertion face creates an interference fit within the passageway for retention. The core pin has a strength rib along most of one side and the forward rib end is tapered to the reduced-dimension pin end section which results in a tapered passageway transition surface to eliminate terminal stubbing during insertion.

Abstract: A system for distributing electrical power to side edges (108, 112) of a daughter card (102) upon insertion into a card cage (10) includes a pair of source and return bus bars (118, 116) mounted on at least one of the side edges and electrically connected by arrays of terminals (172) to power circuits of the card, insulated by a cover (120) having a rail (126) for following the guide channels (18, 20) of the card cage at each card location. Rearward ends of the bus bars have blades (122, 124) which are received into receptacle contacts (46, 44) mounted in the card cage above and below the backplane (14), which are mounted at each card location and electrically connected to source and return busses (68, 58) of the card cage.

Abstract: A bus bar assembly (110) includes a pair of source and return bus bars (118,116) mounted on at least one of the side edges (108,112) of a daughter card (102) and electrically connected by arrays of terminals (172) to power circuits of the card, for use in a system for distributing electrical power to the daughter card module (100) upon insertion into a card cage (10). The pair of bus bars (118,116) is insulated by a cover (120) having a rail (126) for following the guide channels (18,20) of the card cage at each card location. Rearward ends of the bus bars have blades (122,124) which are received into receptacle contacts (46,44) mounted in the card cage above and below the backplane (14), which are mounted at each card location and electrically connected to source and return busses (68,58) of the card cage, with the receptacle contacts (46,44) preferably being float mounted to be easily incrementally moved upon blade receipt during card module (100) insertion.

Abstract: An assembly (42) includes plurality of receptacle contacts (46,44) mounted to a clevis block (66) between respective pairs of salients (86) and along a shaft (64) extending through the salients. The receptacle contacts (46,44) are incrementally moveable after assembly and thus define a floating separable interface for an array of blade shaped contacts (122,124) when assembly (42) is mounted within a card cage (10) and blade shaped contacts are along rearward ends of bus bars (118,116) mounted on upper and lower edges (108,112) of daughter cards (102) insertable into the card cage, defining a system for distributing electrical power from the card cage to the daughter cards.

Abstract: Two flat cables are interconnected to comprise a tap connection or a splice connection by stacking them and pressing together against them an assembly of upper and lower interconnecting structures which include opposing regions of alternating shearing wave shapes and relief recesses. The wave shapes shear the conductors of the cables and extrude the thus-sheared conductor strips into the opposing relief recesses so that newly sheared conductor edges are moved adjacent electrical engagement surfaces defined by vertical edges of the adjacent wave shapes. Dual conductor cables have their respective conductors interconnected by using a pair of assemblies of upper and lower interconnecting structures, each assembly having shearing wave shapes and relief recesses disposed transversely across only the half of the cables within which the appropriate conductors are disposed.

Abstract: A monolithic transition adapter terminated to a flat power cable has one or two plate sections extending forwardly from the termination which conclude in an array of first and second alternating spring contact arms deflectable downwardly and upwardly respectively. The spring arms are formed to include free ends having arcuate contact sections convex in opposing directions comprising a lead-in to receive thereinto a blade-like contact member from forwardly thereof, and facilitating the deflection by the mating contact of the spring arms in the respective opposing directions. A monolithic contact member matable with the transition adapter includes a planar body portion having a forward blade contact and a plurality of terminal sections rearwardly thereof such as for interconnecting with a printed circuit board.

Abstract: A high performance controlled impedance low loss low attenuation cable having the characteristics of a shielded twisted pair cable is disclosed. The cable contains a plurality of pairs of associated conductors located in a single plane to give a low profile flat cable suitable for use in undercarpet wiring installations. The cable comprises a plurality of layers of extruded insulating material with a metal foil shield surrounding only associated pairs of conductors. Insulating material having different dielectric constants is employed in conjunction with the encircling foil shield to give the cable the characteristics of a conventional shielded twisted pair cable.
