An initially integral terminal assembly 84; 94 useful for terminating a selected conductor 74; of a flat power cable 72 having at least two insulated conductors 74, 76 includes upper and lower plate sections 26, 50 extending in diverging directions from a common bendable hinge 46 defining a cable receiving region therebetween. Each plate section 26, 50 has at least a first portion 28, 52 corresponding to the first conductor 74 and a second portion 36, 60 associated with a second conductor 76 of the cable 72. Each portion 28, 52; 36, 60 further includes conductor terminating regions 30, 38, 54, 62 intermediate opposed upstanding side walls 42, 66 of the upper and lower plate sections 26, 50. One of the terminating regions 30, 54; 38, 62 of a selected one of the first or second portions 28, 52; 36, 60 of the plate sections 26, 50 corresponds to a selected cable conductor 74; 76 contains respective arrays of shearing means 32, 56; 40, 64 adapted to penetrate the selected conductor 74, 76 inserted therebetween upon the upper and lower plate sections 26, 50 being pressed together to shear the insulation and the selected conductor 74; 76. The terminating regions 38, 62; 30, 54 of the portions 36, 60; 28, 52 corresponding to the remaining cable conductors 76, 74 are severed from the assembly 84, 94 prior to terminating the assembly to the cable 72. Upon termination the assembly 84; 94 is electrically connected to the selected conductor 74; 76 and electrically isolated from the remaining conductors 76; 74.

Electrical connector for mid-cable termination

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.

Card edge bus bar assembly for power distribution system

A paddle board for a connector for one or two ribbon cables having closely spaced signal and ground wires, includes on one or both major surfaces a plurality of wire-terminating pads comprising conductive material along bottoms of wire-receiving grooves proximate the cable-proximate edge of the board, the grooves defined by serrate ridges. Circuit paths extend from the signal ones of the wire-terminating pads to terminal-connecting pads along one or both major surfaces at a connector-proximate edge of the board to be connected to signal terminals of the connector. Other circuit paths extend from ground ones of the wire-terminating pads to a ground bus which includes at least one ground circuit path extending to a ground terminal-connecting pad along the connector-proximate edge. The wires of each ribbon cable are soldered to the wire-terminating pads after being wiped into the grooves, and the ridges serve as integral wire alignment means. The paddle board is molded of plastic and then plated to define the pads and circuit paths, and can include molded through-holes which become plated, and can also easily have a shape molded to include other structural features such as cable-receiving recesses as desired. A solder strip can be placed transversely across the row of wire ends and melted by a transverse hot bar, with interruptions in the ridges defining a strip- and bar-receiving region.

A socket for a flatpack semiconductor package includes an insulative housing with a plurality of terminal receiving channels which open onto an upper package receiving surface. The channels are in lateral communication with apertures which are profiled for receiving tail portions of the terminals therethrough for interconnection of the tail portions to a printed circuit board. The electrical terminals are disposed within the channels with a contact portion situated above the package receiving face for contact with the flatpack semiconductor package leads. The terminals are designed with a lengthened beam section which forms the contact portion which defines the force deflection characteristics of the terminals to be somewhat insensitive to the insertion depth of the carrier. The housing includes latches on the ends of the housing which are rotatable to accept the carrier and which latch the carrier and package within the housing with the leads of the package loaded against the contact portions of the terminals with predetermined contact force. The latches are also rotatable about axes inward of their latching surfaces so that contact portions are wiped and backwiped against package leads. The contact leads are formed such that the barbs are formed from the area which is used as the carrier strip. The contacts also include widened bending portions which allow for stress relief through the bending radii.

Burn in socket for flat pack semiconductor package

A burn-in test socket for use with flatpack semiconductor components is disclosed. The flatpack burn-in socket is especially adapted for use with robotic assembly techniques. The socket comprises an insulative housing with a plurality of terminals adapted to be in registry with leads on a flatpack semiconductor device located in a conventional flatpack carrier. The terminals are doubly reversely formed to laterally wipe the leads during insertion. Electrical continuity of the socket terminals and dynamic electrical testing of the semiconductor device can be probed from above the socket.
