Abstract
Abstract An insulative torque coupling assembly includes a bolt couple engaging a bolt passing through an aperture in a terminal of an electrical device. An actuator couple formed for engagement by a wrench is torqued to drive the bolt couple through an intermediate insulative couple to turn the bolt pursuant to effecting with relative safety a line bolted electrical connection of the device terminal to an associated switchboard terminal. An insulative sleeve holds the couples in coaxial assembly.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
79 words
An insulative torque coupling assembly for use in making an electrical joint, secured by a bolt, said assembly comprising, in combination: A. a metallic actuator couple having one end configured for engagement by a torquing tool; B. a metallic bolt couple formed to engage the bolt; C. an intermediate insulative couple having ends configured to interfit with ends of said actuator and bolt couples such as to transmit torque therebetween; and D. means holding said couples in coaxial assembly.
Claim 2
Dependent Claim
79 words
An insulative torque coupling assembly for use in making an electrical joint, secured by a bolt, said assembly comprising, in combination: A. a metallic actuator couple having one end configured for engagement by a torquing tool; B. a metallic bolt couple formed to engage the bolt; C. an intermediate insulative couple having ends configured to interfit with ends of said actuator and bolt couples such as to transmit torque therebetween; and D. means holding said couples in coaxial assembly.
Claim 3
Dependent Claim
24 words
The assembly defined in claim 1, wherein said bolt couple is formed at one end with means for engaging the head of the bolt.
Claim 4
Dependent Claim
18 words
The assembly defined in claim 1, wherein said holding means is in the form of an insulative sleeve.
Claim 5
Dependent Claim
15 words
The assembly defined in claim 3, wherein said sleeve is heat shrunk about said couples.
Claim 6
Dependent Claim
24 words
The assembly defined in claim 1, wherein the ends of said couples are formed to provide tongue and groove interfitting torque coupling connections therebetween.
Claim 7
Dependent Claim
37 words
The assembly defined in claim 5, wherein said tongue and groove connection between said actuator couple and said insulative couple is angularly misaligned with said tongue and groove connection between said bolt couple and said insulative couple.
Claim 8
Dependent Claim
23 words
The assembly defined in claim 5, wherein said holding means is in the form of an insulative sleeve heat shrunk about said couples.
Claim 9
Dependent Claim
43 words
The assembly defined in claim 1, wherein said actuator couple is formed having a bolt headed end configuration facilitating engagement by a wrench, said headed end configuration being separated from the couple body by an annular shoulder facilitating mounting said assembly for rotation.
Claim 10
Dependent Claim
24 words
