Round shielded cable and modular connector therefor
First Claim
1. A multi-conductor round cable construction comprising:
- at circularly arranged least one layer containing a plurality of insulated conductors, said plurality of insulated conductors having approximately equal outside diameters;
shielding means comprising a flexible electrically conductive shield surrounding said at least one layer for isolating said at least one layer from external electromagnetic interference;
drain means comprising a single uninsulated conductor contained in said at least one layer of conductors, said uninsulated conductor having an outside diameter approximately equal to the outside diameter of said insulated conductors and being disposed in intimate contact with said shielding means for providing electrical conductivity between said shielding means and said drain means; and
an outer jacket surrounding said shielding means.

Abstract
The cable comprises one or more layers of insulated conductors disposed in circumferentially spaced relation. At least one layer is surrounded by a flexible shield formed from a inner layer of metallic foil bonded to a layer of flexible plastic. A ground conductor in the form of an uninsulated metal wire or a semi-conductive wire is disposed in the conductor layer directly adjacent to the shield. The ground conductor and the insulated conductors all have approximately the same outside diameter. This promotes intimate contact between the ground conductor and the shield.
The cable is used in modular conjunction with a connector which holds the cable in pressurized engagement within a cable receiving opening. The pressure produced by the connector insures that intimate contact between the ground conductor and the shield will be maintained. The connector is designed such that the pressure applied to the cable can be varied.
