Claim 4

An invention as defined in claim 3 wherein said nonresilient member is disc-shaped and said body of elastomeric material is generally cylindrical in configuration, one end of said generally cylindrical body of elastomeric material being fastened to a flattened surface of said disc-shaped nonresilient member.

Claim 5

A voltage grading termination housing for a high voltage electrical conductor comprising a body of insulating material of predetermined configuration molded around a pair of electrically interconnected electrical contacts, handling means mounted adjacent said body to provide tool-engageable surfaces that are adapted to be grasped by a manually operable termination-manipulating tool, resilient coupling means mounted on said body and fastened to said handling means to afford a resilient, force-transmitting connection between said handling means and the housing, said resilient coupling means being constructed as to be operable to yield within a predetermined range of angular movement with respect to said body when subjected to forces transmitted to it from said handling means due to movement thereof when the handling means is operably grasped and moved by a termination-manipulating tool, said resilient coupling means comprising a body of elastomeric material that is mounted on said body of insulated material, and includes a nonresilient member that is fastened to a surface of said body of elastomeric material, saiD nonresilient member also being coupled to said handling means thereby to interpose a relatively rigid stress-distributing member between said handle means and said body of elastomeric material.

Claim 6

A voltage grading termination housing for a high voltage electrical conductor comprising a body of insulating material of predetermined configuration molded around a pair of electrically interconnected electrical contacts, handling means mounted adjacent said body to provide tool-engageable surfaces that are adapted to be grasped by a manually operable termination-manipulating tool, resilient coupling means mounted on said body and fastened to said handling means to afford a resilient, force-transmitting connection between said handling means and the housing, said resilient coupling means being constructed as to be operable to yield within a predetermined range of angular movement with respect to said body when subjected to forces transmitted to it from said handling means due to movement thereof when the handling means is operably grasped and moved by a termination-manipulating tool, said resilient coupling means comprising a body of elastomeric material that is mounted on said body of insulated material, and includes a nonresilient member that is fastened to a surface of said body of elastomeric material, saiD nonresilient member also being coupled to said handling means thereby to interpose a relatively rigid stress-distributing member between said handle means and said body of elastomeric material.

Claim 7

An invention as defined in claim 4 wherein said handling means comprises a hook-eye handle formed of elastomeric material, said cylindrical body of elastomeric material being sufficiently long and flexible to allow the disc-shaped, nonresilient member to be moved through an angular range of at least 10* responsive to a bending force being transmitted to it from said hook-eye handle before the elastomeric material of said handle is stretched beyond a predetermined limit of its elasticity by a torsion force applied to it from a termination-manipulating tool.

Claim 8

An invention as defined in claim 5 wherein said termination housing, said coupling means and said handling means comprise component parts of an integral termination housing that is formed of thermosetting, moldable elastomeric material.

Claim 9

An invention as defined in claim 6 wherein said nonresilient member comprises a disc of electrical insulating material embedded in a coating of elastomeric material that forms an integral part of said termination housing.

Claim 10

An invention as defined in claim 7 including a rigid core member embedded in the elastomeric material of said hook-eye handle thereby to reduce the ability of said handle to elongate in response to forces transmitted to it by a termination-manipulating tool.

Claim 11

An invention as defined in claim 8 wherein said rigid core member is a metal plate having an aperture therein and having a flattened edge that generally parallels a flattened surface of said disc-shaped nonresilient member when said components are in their respective assembled positions on said termination housing, and said disc-shaped nonresilient member comprises a metal plate.

Claim 12

An invention as defined in claim 6 wherein said predetermined configuration for said termination housing forms an elbow, said handling means being mounted on one leg of said elbow closely adjacent the bend therein and on the outer radial surface thereof.

Claim 13

An invention as defined in claim 3 wherein said resilient coupling means includes a second nonresilient member mounted in spaced-apart relation with respect to the other nonresilient member therein, whereby at least a portion of the body of elastic material is positioned between said nonresilient members to thereby reduce the flexibility of said resilient coupling means.
