Method of manufacture for shielded flat electrical cable
First Claim
1. A method for manufacturing a shielded flat cable from a cladding cable having:
- a plurality of parallel conductors of a tape-form arranged horizontally;
an insulating cladding which covers the surface of the conductors and joins the conductors, the cladding having a unitary structure; and
at least one tear-away wire having greater physical strength than the insulating cladding disposed in a direction parallel with the conductors, said wire being placed between at least one conductor and the insulating cladding which covers the conductors;
said method comprising the steps of;
exposing a conductor which is overlaid by a tear-away wire by pulling said tear-away wire in a direction away from the conductor being exposed, so as to cause a portion of the insulating cladding which overlays said tear-away wire to be torn away from an adjacent intact cladding layer, thereby exposing a length of the conductor surface in direct proportion to the length of the wire torn away; and
laying an electrically conductive shield layer in the form of a tape on an exposed surface of the conductor;
bonding the shield layer to the exposed surface of the conductor so as to establish an electrically conducting bonded interface in a longitudinal direction of the exposed surface of the conductor.

Abstract
A method of manufacturing shielded flat cable comprising a plurality of tape form conductors, arranged in a horizontal plane, and in parallel fashion, and insulation cladding which covers the surfaces of the conductors and is unitary in structure, and using a cladding cable which is formed by the placing of a tear-away wire, comprising materials having a greater physical strength than the insulation cladding, between at least one of the plurality of the conductors and the insulation cladding covering this conductor, in which, in the exposure of a conductor which is overlaid by the tear-away wire, the tear-away wire, along with the area of the insulation cladding which overlays this tear-away wire, is pulled in an angled direction with respect to the surface, and after this a shield layer comprising conductive materials and having a tape form is laid on the surface of the cladding cable and the shield layer is brought into electrical contact with the exposed conductor.
