A transition adapter for terminating flat power cable includes at least a stamped and formed member having opposed plate sections between which an end or an edge portion of the cable is receivable to be terminated. The plate sections have opposing cooperating terminating regions comprised of a plurality of alternating wave shapes and relief recesses, with each wave shape aligned with a recess of the opposing terminating region. When the plate sections are urged together under sufficient force, shearing edges along each side of each wave shape shear the cable conductor by cooperating with shearing edges of the adjacent wave shape of the opposing terminating region, scissors-fashion. Crests of the wave shapes deflecting the sheared cable portions into the opposing relief recesses, forming a series of interlocking wave joints across the intermeshing terminating regions and terminating the cable between the plate sections. The wave crests deflect integral strips of conductor out of the plane of the cable, exposing sheared conductor edges for electrical connection therewith such as with solder. Softer metal insert members may be secured to and along outer surfaces of the plate sections to engage and form gas-tight electrical connections with substantial surface areas of the sheared conductor edges.

Electrical terminal for wave crimp termination of flat power cable

A pair of transition adapter terminals especially useful for terminating respective conductors of a dual conductor flat power cable, include respective contact sections at forward ends thereof. Cable-receiving slots across rearward ends thereof extend between pairs of integral bight straps or hinge sections joining upper and lower terminal plate sections. The slots receive respective tab-shaped portions of flat power cable insertably thereinto which are then disposed between the opposed slightly spaced upper and lower plate sections. The plate sections include opposing arrays of shearing waves shapes alternating with relief recesses transversely across, with each wave shape opposed from a respective relief recess. When the plate sections are pressed together, the opposing arrays of wave shapes shear the insulation and the conductor of the tab-shaped cable portion therebetween and simultaneously extrude the sheared conductor strips into the opposed relief recesses, exposing sheared conductor edges for enabling electrical connections therewith. The cable is prepared by cutting an axial slot along the centerline preferably dimensioned so that the exposed inwardly facing conductor edges are bitten into by the adjacent bight straps upon pressing together the plate sections.

Electrical terminals and method for terminating flat power cable

Relief against torque for a terminal terminated to an end portion of a flat conductor cable is provided by a low height rearward section of a metal member having opposed sections forwardly of a cable-receiving end having a transverse cable-receiving slot. The cable end is inserted through the slot for termination forwardly of the cable-receiving end and disposed between the opposed sections. The opposed sections are joined together by a pair of integral spaced bight straps or hinge sections beside the cable at the ends of the slot. The straps or hinges enable the metal member to resist torque applied to the termination by the cable. The metal member can be the terminal itself, a transition adapter for termination to flat electrical cable of the type having opposed plate sections applied to the major cable surfaces which include means for mechanical and electrical connections therewith. A pair of elongate flanges can extend along the sides of the slot and outwardly away from the major cable surfaces to provide strength ribs to prevent torque from the cable from prying apart the plate sections of the adapter after termination.

Strain relief for flat cable termination

An improved cable having low crosstalk characteristics is comprised of a pair of multi-conductor cable members laminated together with the pairs of wires of and between the respective cable members being so spaced as to effectively form a balanced capacitive bridge configuration. The conductors of the cable members can be either round or flat in section and the cable members are preferably secured together across their entire width by means which allows the cables to be readily separated at the termination. This capability for separation of the cable members is also effective for inserting a tap means intermediate the ends of the cable.
