Abstract
Abstract A safety connector for high energy electrical distribution systems. An output bushing or source plug on a source of power, such as a transformer has an apertured insulating body having a conductive portion at each end. An apertured T-shaped insulating sleeve includes an intersecting apertured distribution conductor at a position intermediate its ends that is held in place by an apertured bushing. One end of the insulating sleeve receives the output bushing, and the other end receives one or the other of a pair of connect or disconnect plugs. The connect plug has an axially extending conductive portion that extends through the aperture in the distribution conductor and the apertured body of the output bushing to conductively engage the conductive portion at one end of the output bushing. The disconnect plug has a conductive portion extending axially from one end to another so that one end may be grounded while the other end is in conductive engagement with the aperture in the distribution conductor. The plugs are provided with indicia to show the status of the connector.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
A safety connector comprising in combination; a. a source plug having a centrally disposed aperture extending longitudinally of an insulated body and conductive portions at first and second ends thereof: b. a T-shaped insulating sleeve having a longitudinally extending aperture in each of the first, second and third legs thereof, said second leg being disposed on said source plug, said second and third legs being in axial alignment; c. a distribution conductor disposed in the first leg of said Tshaped sleeve, said conductor having an aperture disposed intermediate the second and third legs of said T-shaped bushing; and d. plug means, operable to engage the end of the distribution connector, disposed in the third leg of said T-shaped bushing.
Claim 2
Dependent Claim
119 words
A safety connector comprising in combination; a. a source plug having a centrally disposed aperture extending longitudinally of an insulated body and conductive portions at first and second ends thereof: b. a T-shaped insulating sleeve having a longitudinally extending aperture in each of the first, second and third legs thereof, said second leg being disposed on said source plug, said second and third legs being in axial alignment; c. a distribution conductor disposed in the first leg of said Tshaped sleeve, said conductor having an aperture disposed intermediate the second and third legs of said T-shaped bushing; and d. plug means, operable to engage the end of the distribution connector, disposed in the third leg of said T-shaped bushing.
Claim 3
Dependent Claim
52 words
The apparatus of claim 1 in which the plug means includes a conductor extending from one end through the aperture in the distribution conductor through the conductive portion at the second end of said source plug, and into conductive engagement with the conductive portion at the first end of said source plug.
Claim 4
Dependent Claim
57 words
The apparaTus of claim 2 in which the source plug, the T-shaped insulating sleeve and the plug means are so dimensioned as to provide a compression engagement between adjacent side faces of the conductor on the plug means, the side faces of the distribution conductor, and the side face of the second end of the source plug.
Claim 5
Dependent Claim
34 words
The apparatus of claim 1 in which a circuit bushing having an internal threaded aperture on an external threaded portion is threadably disposed in the threaded aperture in the end of the distribution conductor.
Claim 6
Dependent Claim
34 words
The apparatus of claim 2 in which a circuit bushing having an internal threaded aperture on an external threaded portion is threadably disposed in the threaded aperture in the end of the distribution conductor.
Claim 7
Dependent Claim
34 words
The apparatus of claim 3 in which a circuit bushing having an internal threaded aperture on an external threaded portion is threadably disposed in the threaded aperture in the end of the distribution conductor.
Claim 8
Dependent Claim
20 words
The apparatus of claim 2 in which the apertures in the sleeve and the plugs are of complementary tapered configuration.
Claim 9
Dependent Claim
25 words
The apparatus of claim 1 in which the plug means includes a conductor extending therethrough into conductive engagement with the aperture in the distribution conductor.
Claim 10
Dependent Claim
16 words
The apparatus of claim 8 in which the conductor includes a terminal at the other end.
Claim 11
Dependent Claim
34 words
The apparatus of claim 8 in which a circuit bushing having an internal threaded aperture on an external threaded portion is threadably disposed in the threaded aperture in the end of the distribution conductor.
Claim 12
Dependent Claim
30 words
The apparatus of claim 8 in which a side of the conductor in the plug is in effective conductive engagement with the side of the distribution conductor adjacent said aperture.
