Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
240 words
An electrical cable terminal assembly, comprising: (A) an elongated, hollow, electrically-conducting plug having an internal socket extending along a longitudinal axis, said socket being dimensioned for electrically receiving an electrical conductor of an electrical cable inserted into the plug through one end thereof; (B) a soft, flexible, transparent material, electrically-insulating body mounted at said one end for rotation in either circumferential direction about said longitudinal axis, said body including (i) a bore coaxial with the socket, said bore being dimensioned for receiving the electrical cable during insertion of the conductor into the socket, (ii) an elongated hollow holder having transparent walls bounding an internal recess extending along a radially offset axis which is generally parallel to said longitudinal axis, said recess being dimensioned for interiorly receiving cable marking elements arranged lengthwise along the offset axis, said cable marking elements bearing indicia for identifying the cable, (a) said holder being integral with, and of the same transparent material as, the body to enable the indicia to be visible through, and protected by, said transparent walls, and (b) said holder being mounted for joint rotation with the body to enable the indicia to be rotated about said longitudinal axis to a desired position to facilitate viewing of the marking elements; and (C) means at said one end of the plug for preventing relative movement along said longitudinal axis between the body and the plug while allowing said rotation to the desired position.
Claim 2
Dependent Claim
240 words
An electrical cable terminal assembly, comprising: (A) an elongated, hollow, electrically-conducting plug having an internal socket extending along a longitudinal axis, said socket being dimensioned for electrically receiving an electrical conductor of an electrical cable inserted into the plug through one end thereof; (B) a soft, flexible, transparent material, electrically-insulating body mounted at said one end for rotation in either circumferential direction about said longitudinal axis, said body including (i) a bore coaxial with the socket, said bore being dimensioned for receiving the electrical cable during insertion of the conductor into the socket, (ii) an elongated hollow holder having transparent walls bounding an internal recess extending along a radially offset axis which is generally parallel to said longitudinal axis, said recess being dimensioned for interiorly receiving cable marking elements arranged lengthwise along the offset axis, said cable marking elements bearing indicia for identifying the cable, (a) said holder being integral with, and of the same transparent material as, the body to enable the indicia to be visible through, and protected by, said transparent walls, and (b) said holder being mounted for joint rotation with the body to enable the indicia to be rotated about said longitudinal axis to a desired position to facilitate viewing of the marking elements; and (C) means at said one end of the plug for preventing relative movement along said longitudinal axis between the body and the plug while allowing said rotation to the desired position.
Claim 3
Dependent Claim
20 words
The assembly as recited in claim 1, wherein each cable marking element is a ring frictionally received in the recess.
Claim 4
Dependent Claim
25 words
The assembly as recited in claim 1, wherein said means at said one end of the plug is an annular flange having a curved cross-section.
Claim 5
Dependent Claim
28 words
The assembly as recited in claim 1, wherein said body is constituted of an injection-molded, synthetic plastic material, and wherein said plug is constituted of a metal material.
