Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
278 words
A flex-resistant protective insulating covering for a modular high voltage electrical distribution junction assembly, comprising a plurality of generally cylindrical elastomeric hollow insulating body members closed at one end and open at the other edn for insertion of a perforate cable terminal lug, each but one of said body members being formed with a conical socket at one side and a conical plug at the opposite side and along a common axis perpendicular to the axis of the hollow interior of said plug and adjacent the closed end, said one body member being a terminal body member formed with but one of said socket and plug, and a terminal cap member complementing said one body member and being formed with the other of said socket and plug, thereby permitting assembly of said members in closed linear relationship along the line of said common axis; each said member having an outer conductive layer mating at the edges with the conductive layer of any adjacent member to form a continuous conductive shield about said assembly; each of said body members being provided with a semiconductive liner integral therewith and shaped to fit snugly about a cable terminal lug inserted in the body member and to extend part way along any inner conical socket surface of said body member; and said members being further characterized in that the conical socket surfaces are formed at an angle with the axis of between 15* and 45* and the conical plug surfaces are formed at an angle with the axis which angle is greater than the socket surface angle by an amount of between about 3* and about one-third of said socket surface angle.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
13 words
The insulating covering of claim 1 wherein the socket angle is about 30*.
Claim 4
Dependent Claim
27 words
The insulating covering of claim 1 wherein said terminal body member is formed with a conical socket and said terminal cap member has the conical plug configuration.
Claim 5
Dependent Claim
25 words
A modular high voltage electrical distribution junction assembly including a plurality of interconnected cable terminal lugs within a protective insulating covering as defined in claim
