摘要:
A tap or splice connector especially useful for a pair of dual conductor flat power cables (12,14) includes two pairs of upper and lower structures (60,80) which are applied to the stacked in-line cables side-by-side and then enclosed in a housing (16,18). The upper and lower structures (60,80) each have a transverse array of cable-engaging wave-shaped bosses alternating with wave-receiving relief recesses when pressed together, so that the waves press trips of both cables in upper and lower arrays into the opposing recesses thus exposing conductor edges of the strips for electrical connection. Outer surfaces of the structures (60,80) are then staked (54,58) to urge the metal thereof laterally and tightly against the conductor edges adjacent thereto. The structures (60,80) preferably are self-locking upon being staked to secure the upper and lower structures (60,80) to each other and to the cables (12,14).

A transition adapter for terminating single or dual conductor flat power cable (214) includes at least a stamped and formed member (208) having one or opposed plate sections (202) against or between which an end or edge portion of the cable is receivable to be terminated. Opposed plate sections (202) have opposed transverse arrays of shearing wave shapes (222) alternating with arcuate shapes defining relief recesses (224), with each wave shape opposing a relief recess and the lateral edges of the opposing arrays of shearing wave shapes cooperating as shearing edges. When the plate sections are urged together against the cable therebetween, the shearing edges shear the cable insulation and conductor into strips while the crests the wave shapes deflect the sheared cable portions into the opposing relief shapes thus exposing sheared conductor edges for electrical connections therewith and forming mechanical and electrical connections with the cable. Copper insert members (228) may be secured along the plate sections and have apertures into which the sheared conductor strips are deflected, and the insert members (228) may be staked forcing metal against the sheared conductor edges for gas-tight connections. A pair of such adapters may be used to terminate dual conductor cable.
摘要:
A connector system is disclosed for distributing power to daughter cards (14) inserted along opposing channels (30,30′) in a card cage (10) having a backplane (76) for connection with the card for signal transmission. Power is received along one or both lateral edges (36,36′) of the card, and the card cage includes a connector (26) for each power-receiving edge (36,36′) of a card (14) mounted on framework (12) of the card cage (10). Each connector (26) has terminals (82) connected to power conductors and includes a card-receiving channel (30) having an open end. Upon full card insertion, the card (14) is locked in position within the connector (26); the connector (26) is then actuated, camming contact sections of its terminals into electrical engagement with power contact means along the card edge (36,36′). Each daughter card (14) is thus powered and correspondingly disconnectable independently of the other daughter cards. An interference arrangement prevents the connector (26) from being actuated unless the card is locked in position, and prevents unlocking and removal of the card unless the connector (26) is deactuated. A dielectric rail (32,32′) mounted along the card edge (36,36′) is shaped to fit the channel (30,30′) and protect the card edge and power contact means therealong exposed in recesses of the rail (32,32′). The card (14) may receive power along both lateral edges (36,36′) if inserted between opposing connectors (26).
