Abstract

A shielded tri-lead conductor is skived to remove upper and lower section of the outer insulation parallel to the long axis of the elliptical cross-sectional shape of the conductor. This operation removes a sufficient bulk of the conductor insulation and also removes the forces that tend to restore the conductor to its elliptical shape so that the end of the cable can be crimped within the insulation-retaining portion of a connector.

Method for Assembling Coaxial Cable and Connector

A shielded tri-lead conductor is skived to remove upper and lower section of the outer insulation parallel to the long axis of the elliptical cross-sectional shape of the conductor. This operation removes a sufficient bulk of the conductor insulation and also removes the forces that tend to restore the conductor to its elliptical shape so that the end of the cable can be crimped within the insulation- retaining portion of a connector.

In one familiar cable, a center conductor carries a signal and two outer conductors add ground potential and form a shield. In a shielded version of this conductor, the center conductor is enclosed in a layer of expanded TEFLON* insulation and a conductive foil is wrapped around this insulation and the co- planer ground conductors. These components are enclosed within an outer plastic coating, and the entire cable has an oval cross section. Both the long axis and the short axis of this oval shape are somewhat larger than the corresponding dimensions of the unshielded cable.

In a connector for a number of these cables, the insulation is stripped from the signal conductor and the ground conductors forced a sufficient distance apart to permit a solder connection to a conductor. The connector structure also grips a short section of the insulated cable behind the electrical connection. To reduce the cross sectional size of the cable in the region where this strain relief connection is mad...
