Abstract

Abstract An insulated clamp is provided for attachment to a cap or connector and for clamping a cable terminating in the cap or connector. The clamp includes an insulating lower cover for the cap or connector, a set of clamping cleats cooperating on ramps in the lower cover, and an insulating upper cover engaged with the lower cover by threads on confronting surfaces thereof. The lower cover has a generally tubular form and includes at its lower end an external hand gripping surface and internal means for attachment to and about the wire terminals of a cap or connector. The lower cover also has at its upper end a set of threads on an external surface and an internal set of ramps spaced radially around its inner periphery. The set of clamping cleats is mounted on a pliable band and the individual cleats have a double wedge form. The cleats are symetrically spaced around the band at stations matching the ramps of the lower cover. The upper cover has an external hand gripping surface and an internal threaded surface, the threads of which match the external threads of the lower cover. The upper cover also has an internal continuous ramp at its upper surface for cooperation with the upper wedges of the set of cleats. When the threads of the upper and lower covers are engaged and they are turned relative to one another, the cleats are forced inward by interaction of the ramps and double wedges to clamp a cable therebetween.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 126 words
A cable clamp comprising a first and a second tubular housing, said housings being axially aligned and having external hand grip surfaces to permit opposite rotation thereof, said housings having a set of cooperating threads to induce axial movement responsive to opposite rotation thereof, and said housings being adapted to having a cable pass therethrough, a set of double wedge cable grip cleats positioned within said housings, ramp means supported on the interior of said first and of said second housing, said ramp means bearing against and being meshed with said set of double wedge cleats, an axial movement of said tubular housings inducing radial inward movement of said double wedge cleats, and said cleats cooperating on inward movement thereof to grip a cable passing therethrough.
Claim 2
Dependent Claim 126 words
A cable clamp comprising a first and a second tubular housing, said housings being axially aligned and having external hand grip surfaces to permit opposite rotation thereof, said housings having a set of cooperating threads to induce axial movement responsive to opposite rotation thereof, and said housings being adapted to having a cable pass therethrough, a set of double wedge cable grip cleats positioned within said housings, ramp means supported on the interior of said first and of said second housing, said ramp means bearing against and being meshed with said set of double wedge cleats, an axial movement of said tubular housings inducing radial inward movement of said double wedge cleats, and said cleats cooperating on inward movement thereof to grip a cable passing therethrough.
Claim 3
Dependent Claim 25 words
The clamp of claim 1 wherein the axially outward movement of the tubular housings results in a radially outward movement of the double wedge cleats.
Claim 4
Dependent Claim 16 words
The clamp of claim 1 wherein the double wedge cleats are mounted to a resilient band.
Claim 5
Dependent Claim 17 words
The clamp of claim 3 wherein the double wedge cleats are formed integrally with a resilient band.
Claim 6
Dependent Claim 27 words
The clamp of claim 1 wherein the double wedge cable grip cleats are three in number and the three cleats are set equidistantly around the tube interior.
Claim 7
Dependent Claim 23 words
The clamp of claim 1 wherein the first tubular housing has internal means for securing a separable cable termination at least partially therein.
Claim 8
Dependent Claim 30 words
The clamp of claim 1 wherein the first tubular housing has internal means for securing a separable cable termination proximate one end and has external threads proximate the opposite end.
