Abstract
Abstract A terminator and grounding device particularly for an underground distribution cable having a concentric grounded neutral. A deformable metal sleeve has an annular space between side wall portions thereof to receive and terminate the helically wound neutral conductor. A steel liner in the deformable metal sleeve resists crushing and provides a through passage for the insulated distribution conductor. A tubular deformable metal side gripper on the main sleeve receives an extrinsic ground wire.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
106 words
A terminator and grounding unit for a cable having a central insulated conductor and an external concentric bare neutral conductor, said unit comprising a deformable metal sleeve to receive said insulated conductor and having an annular side wall chamber formed in one end thereof and terminating deeply within the sleeve for receiving said concentric neutral conductor, whereby the sleeve may then be externally pinched to lock the concentric neutral conductor firmly in said chamber, and a side radially extending deformable metal tube on said sleeve adapted to receive an extrinsic ground conductor and to be pinched thereon to lock the ground conductor securely within said tube.
Claim 2
Dependent Claim
106 words
A terminator and grounding unit for a cable having a central insulated conductor and an external concentric bare neutral conductor, said unit comprising a deformable metal sleeve to receive said insulated conductor and having an annular side wall chamber formed in one end thereof and terminating deeply within the sleeve for receiving said concentric neutral conductor, whereby the sleeve may then be externally pinched to lock the concentric neutral conductor firmly in said chamber, and a side radially extending deformable metal tube on said sleeve adapted to receive an extrinsic ground conductor and to be pinched thereon to lock the ground conductor securely within said tube.
Claim 3
Dependent Claim
37 words
A terminator and grounding unit as defined in claim 1, and said sleeve having a comparatively short solid portion at its end away from said chamber, and said side metal tube being joined to said solid portion.
Claim 4
Dependent Claim
42 words
A terminator and grounding unit as defined in claim 1, and a substantially rigid liner within the bore of said deformable metal sleeve to resist crushing and destruction thereof during pinching of the exterior of the sleeve on said concentric neutral conductor.
Claim 5
Dependent Claim
27 words
A terminator and grounding unit as defined in claim 3, and said rigid liner comprising a steel tube fixed within the bore of said deformable metal sleeve.
