Abstract
Abstract An electrically insulating bushing presenting one or more prongs which so project that, with the bushing incorporated in an electrical connector assembly in which an end portion of an electric cable is connected to, for example, a junction box, the bushing being disposed within the connector with a cylindrical portion of the bushing disposed between the electrical conductors and the outer casing of the electric cable, the ends of the prongs project from the connector to be visible externally of the connector assembly, either with or without the removal of an element of the connector. Thus, although removal of an element of the connector may be required in order to permit inspection of the connector assembly to ensure that a bushing has been installed therein, such inspection can be performed without requiring dismantling of the connector assembly. The projecting ends of the prongs present informational indicia concerning, for example, the size of the bushing, each prong being of segmental form in cross section with the arcuate face thereof facing towards, and the flat face thereof facing away from, the longitudinal axis of the bushing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
96 words
A bushing comprising a tubular portion having a longitudinal axis, and a flange portion which is presented at one end of the tubular portion and which projects outwardly from and around the tubular portion, wherein the flange portion presents at least one prong which projects from the flange portion in a direction opposite from the direction in which the tubular portion projects from the flange portion, said at least one prong being of approximately segmental form in cross section with the arcuate face of the prong directed substantially towards the longitudinal axis of the tubular portion.
Claim 2
Dependent Claim
96 words
A bushing comprising a tubular portion having a longitudinal axis, and a flange portion which is presented at one end of the tubular portion and which projects outwardly from and around the tubular portion, wherein the flange portion presents at least one prong which projects from the flange portion in a direction opposite from the direction in which the tubular portion projects from the flange portion, said at least one prong being of approximately segmental form in cross section with the arcuate face of the prong directed substantially towards the longitudinal axis of the tubular portion.
Claim 3
Dependent Claim
15 words
A bushing according to claim 1, wherein the tubular portion is of substantially cylindrical form.
Claim 4
Dependent Claim
30 words
A bushing according to claim 1, wherein said at least one prong comprises a plurality of prongs which are substantially equi-angularly spaced about the longitudinal axis of the tubular portion.
Claim 5
Dependent Claim
28 words
A bushing according to claim 1, wherein the end portion of said at least one prong remote from the flange portion presents informational indicia relating to the bushing.
Claim 6
Dependent Claim
58 words
A bushing according to claim 1, wherein the end portion of said at least one prong remote from the flange portion is of tapered form, with thE end of said at least one prong remote from the flange portion disposed on the side of the prong which is directed substantially towards the longitudinal axis of the tubular portion.
Claim 7
Dependent Claim
17 words
A bushing according to claim 1, wherein the bushing is integrally formed of linear polyethylene or nylon.
Claim 8
Dependent Claim
138 words
A bushing comprising a tubular portion having a longitudinal axis, and a flange portion which is presented at one end of the tubular portion and which projects outwardly from and around the tubular portion, wherein the flange portion presents at least one prong which projects from the flange portion in a direction opposite from the direction in which the tubular portion projects from the flange portion, said at least one prong being of approximately segmental form in cross section with the arcuate face of the prong directed substantially towards the longitudinal axis of the tubular portion, and the end portion of said at least one prong adjacent to the flange portion being of circular form in cross section and merging with the remaining portion of the prong of approximately segmental form in cross section through a concave fillet.
Claim 9
Dependent Claim
138 words
A bushing comprising a tubular portion having a longitudinal axis, and a flange portion which is presented at one end of the tubular portion and which projects outwardly from and around the tubular portion, wherein the flange portion presents at least one prong which projects from the flange portion in a direction opposite from the direction in which the tubular portion projects from the flange portion, said at least one prong being of approximately segmental form in cross section with the arcuate face of the prong directed substantially towards the longitudinal axis of the tubular portion, and the end portion of said at least one prong adjacent to the flange portion being of circular form in cross section and merging with the remaining portion of the prong of approximately segmental form in cross section through a concave fillet.
