A flat coaxial cable assembly comprising a plurality of parallel coaxial cables disposed in coplanar configuration, each cable being self-contained and with a center conductor, dielectric material around the conductor and a shield of conductive material around the dielectric material, a plurality of drain wires disposed between alternate pairs of adjacent coaxial cables, the drain wires having conductive contact with the shields of the pair of adjacent cables, and a sheath of insulating material encasing the cables and the drain wires with portions thereof on opposite sides of the cables bonded together by way of the spaces between the cables where the drain wires are omitted and at the sides of the outermost cables.

Miniature coaxial cable assembly

Lamination of thermoplastic fluorocarbon resins with unsintered, extruded PTFE is accomplished in order to insulate products, such as conductors in the manufacture of multiconductor cable, by drawing the unsintered PTFE containing the product embedded in it pressed against the thermoplastic fluorocarbon resin through a sintering zone to melt the thermoplastic resin and snter the PTFE, thereby laminating the two together. In the preferred arrangement a second PTFE tape, which can be sintered or unsintered tape, is also laminated at the same time to the thermoplastic resin, such that the final product essentially presents PTFE outer surfaces with thermoplastic fluorocarbon resin bonding the layers of PTFE.
