Abstract
Abstract A shielded cable comprises a flat electrical insulator having a plurality of parallel spaced-apart conductors. A pluraity of openings extend through the insulator to expose at least one conductor. The shield, which is formed from an electrically conductive coating, not only covers the exterior of the insulator but also enters the openings and is electrically connected to the conductor. Gaps are created in the electrically conductive coating so as to provide areas for interconnection by an insulation displacement connector which "mass-terminates" all of the conductors. The exposed one conductor, which is in contact through the openings with the electrically conductive coating, maintains the electrical continuity of the shield notwithstanding the gap formed therein.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
85 words
A process of producing a mass terminable shielded electrical cable having a plurality of side by side spaced-apart conductors enclosed in insulation comprising the steps of: establishing repeated electrical contacts between electrically conductive shield material on the insulation and at least one of the conductors; and creating a gap in said electrically conductive material for enabling terminations to be made respectively to the conductors and to the electrically conductive material, the repeated electrical contacts maintaining electrical continuity of the electrically conductive material across the gap.
Claim 2
Dependent Claim
85 words
A process of producing a mass terminable shielded electrical cable having a plurality of side by side spaced-apart conductors enclosed in insulation comprising the steps of: establishing repeated electrical contacts between electrically conductive shield material on the insulation and at least one of the conductors; and creating a gap in said electrically conductive material for enabling terminations to be made respectively to the conductors and to the electrically conductive material, the repeated electrical contacts maintaining electrical continuity of the electrically conductive material across the gap.
