ELECTRICAL CONNECTOR
First Claim
1. A connector terminating the end of a coaxial cable, said cable including a center conductor, a coaxial shield separated from the center conductor by dielectric material and an outer expandable insulating jacket covering the shield;
- the connector comprising a tubular electrically conductive mandrel having a shank portion extending coaxially inside the shield between the shield and the dielectric and in electrical contact with the shield displacing parts of the shield and jacket outwardly;
an electrically conductive connection means for joining the cable to a complementary conductor, means electrically engaging and mechanically joining the connection means with the mandrel, and a locking sleeve of a size larger than the outer dimensions of the shank of the mandrel, and which fits over the cable outside the jacket, the sleeve being separate from the connection means and axially movable with respect to the mandrel, and having internal threads engaging the outer surfaces of the jacket around the shank portion of the mandrel, the threads engaging the jacket and pressing the shield and jacket between the mandrel and locking sleeve, thereby holding the shield in electrical and mechanical contact with the mandrel.

Abstract
This invention relates to a connector for terminating the end of a cable, the cable including a center conductor, a coaxial shield separated from the center conductor by dielectric material, and an outer insulating jacket covering the shield. The connector includes a mandrel having a shank portion extending between the dielectric material and the shield, a connection means in electrical engagement with the mandrel, and means for holding the shank portion of the mandrel between the shield and dielectric material.

-
2. The connector of claim 1, wherein the mandrel is externally tapered and displaces the shield and jacket outwardly in a tapering manner, and the locking sleeve being threaded on the tapering part of the jacket to progressively increase the compressive forces thereon.
-
3. The connector of claim 1 wherein the mandrel has a shoulder around it beneath the locking sleeve resisting withdrawal of the mandrel from the sleeve.
