Abstract
Abstract This invention is a support formed from a flat strip that is bent around electric cable and that has its ends interlocked to form a short section of tubing which is inserted between the insulation shield and the metal shield that surrounds the insulation shield. It is used at splices and other terminations to support the metal shield so that contact rings, connectors and the like can be clamped to the outside of the metal shield without exerting force on the insulation of the cable. cable.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
185 words
In a high tension electric transmission line that has a cable including a conductor, insulation surrounding the conductor, an insulation shield and an outer shield around the outside of the insulation shield and in the circuit therewith, the combination with said outer shield of a support ring located between the insulation shield and the outer shield at a termination of the cable, the support ring being formed from a flexible band having a length greater than the circumference of the insulation shield and having end portions that engage one another to provide a minimum circumference for the ring when the band is bent to form a ring with the ends of the band engaged with one another, the ring being of limited radial thickness that can be inserted between the insulation shield and the outer shield of the cable, an element in contact with the outside of the outer shield and having electric continuity therewith, and a hose clamp that fits over the outer shield and over said element for clamping the outer shield and said element against each other and against the support ring.
Claim 2
Dependent Claim
185 words
In a high tension electric transmission line that has a cable including a conductor, insulation surrounding the conductor, an insulation shield and an outer shield around the outside of the insulation shield and in the circuit therewith, the combination with said outer shield of a support ring located between the insulation shield and the outer shield at a termination of the cable, the support ring being formed from a flexible band having a length greater than the circumference of the insulation shield and having end portions that engage one another to provide a minimum circumference for the ring when the band is bent to form a ring with the ends of the band engaged with one another, the ring being of limited radial thickness that can be inserted between the insulation shield and the outer shield of the cable, an element in contact with the outside of the outer shield and having electric continuity therewith, and a hose clamp that fits over the outer shield and over said element for clamping the outer shield and said element against each other and against the support ring.
Claim 3
Dependent Claim
58 words
The combination described in claim 1 characterized by one end of the band being formed with abutments between which the other end of the band extends when the band is formed into a ring, the abutments holding said other end against radial movement and against circumferential movement in a direction that would decrease the diameter of the ring.
Claim 4
Dependent Claim
75 words
The combination described in claim 2 characterized by the edge portion of the band at said other end being of the same cross-section as the part of the ring back from said edge portion whereby the diameter of the support ring can be changed by trimming off said edge portion at said other end of the band and without affecting the cooperation of the ends of the band when brought together to form a ring.
Claim 5
Dependent Claim
63 words
The combination described in claim 1 characterized by the one end of the band having edge portions in planes that diverge from one another and between which the other end of the band extends to bottom on said end portions at the vertex of a dihedral angle where planes of the diverging end portions intersect at the inner ends of said end portions.
Claim 6
Dependent Claim
74 words
The combination described in claim 1 characterized by one end of the band having cuts therein extending inward from the edges of the band, and the material of the band on one side of each cut being bent away from the plane of the material on the other side of the cut to provide angularly related tabs between which the other end of the band engages when the band is formed into a ring.
Claim 7
Dependent Claim
68 words
The combination described in claim 1 characterized by the band being made of two strips of material superimposed on one another and connected together to form an integral band, but having portions at one end of the band diverging as they approach that end of the band to form a trough into which the other end of the band extends when the band is formed into a ring.
Claim 8
Dependent Claim
72 words
The combination described in claim 1 characterized by the outer shield and the element in electric contact therewith being corrugated with the length of the corrugations running generally circumferentially, and the band being corrugated with the corrugations running generally lengthwise of the band and in position to interlock with the corrugations of the outer shield and said element when the band is formed into a ring and inserted into the outer shield.
Claim 9
Dependent Claim
57 words
The combination described in claim 7 characterized by the element in electrical contact with the outer shield being a connector for joining the outer shield with a corresponding outer shield of another length of cable, and said connector extending axially substantially beyond the outer shield of the cable to which it is connected by the hose clamp.
Claim 10
Dependent Claim
33 words
The combination described in claim 1 characterized by the insulation shield being a semi conductor and the support ring and outer shield being made of metal that is a good conductor of electricity.
Claim 11
Dependent Claim
41 words
The combination described in claim 1 characterized by said element in electrical contact with the outer shield bEing a contact ring, and an electrical grounding lead connected to the contact ring at a location beyond the side of the hose clamp.
Claim 12
Dependent Claim
106 words
The combination described in claim 1 characterized by the conductor, insulation, insulation shield and outer shield being parts of a first cable, a second cable having parts similar to those of the first cable and having the conductor of the first cable connected with the conductor of the second cable, the element in contact with the outer shield being a connector that also contacts with the outer shield of the second cable, and the second cable having a hose clamp securing the connector to the outer shield of the second cable in a manner similar to the clamping of the outer shield to the first cable.
Claim 13
Dependent Claim
58 words
The combination described in claim 11 characterized by the outer shields of both cables and the connector having similar corrugations extending generally circumferentially thereof with the corrugations held in engagement with one another by the clamping of pressure of the hose clamps to lock the outer shields of the cables against axial displacement with respect to one another.
Claim 14
Dependent Claim
62 words
The combination described in claim 1 characterized by the outer shield being corrugated with the corrugations extending generally circumferentially around the shield, and the support ring being made of corrugated material with the corrugations similar to those of the outer shield and in position to interlock with the corrugations of the outer shield when the ring is inserted into the outer shield.
