摘要:
A flat cable for use with a mass termination connector having a plurality of regularly spaced terminal elements. The flat cable includes a laminated carrier film and a plurality of discrete conductors held in regularly spaced parallel relationship by the carrier film to match the terminal element spacing of the connector. Each conductor has an insulating jacket made of a thermoplastic material. The carrier film includes an attachment layer of thermoplastic insulation having a melting temperature similar to that of the jacket material, and a dimensional stabilization layer made of an insulative material having a melting temperature higher than those of the attachment layer and the jacket material and displaying dimensional stability at the melting temperatures of the attachment layer and jacket material. The jackets of the conductor are fused to the attachment layer, and the attachment layer is held by the stabilization layer. The carrier film can be longitudinally discontinuous to form first cable sections where the conductors are held parallel for ease of termination, and second cable sections where the conductors are not held to increase flexibility and reduce weight. The cable can also be formed into a round configuration to provide advantages during routing. A method of manufacturing this cable is also disclosed.
摘要:
A flat cable assembly for use with a mass termination connector. The cable assembly includes a main cable having a plurality of conductors held in regularly spaced parallel re- lationahip in a sheet of insulation to match the terminal element epaclng of the connector. The main cable has a first surface, a second surface and lateral ends with the surfaces extending between the ends. A plastic covering having an interior surface facing the main cable second surface is provided. A release agent is printed on either or both of the interior surface of the plastic covering and the second surface of the main cable so that portions of the printed upon surface are coated by the release agent and other portions of that surface are uncoated. A metallic ground plane is positioned between the main cable and the covering with the plastic covering being bonded to the second surface at the uncoated portions so that the plastic covering can be readily separated from the main cable to expose the ground plane.
