Abstract
Abstract A tubular, conductive housing has an axial opening defining an inner surface. An annular, outer lip projects from the inner surface. A centrally located axle within the housing has an annular inner lip opposing the outer lip. Cylinders at either end of the housing engage the axle in the housing and have apertures therein through which wires are inserted and located between the lips. Rotating the cylinders results in the wires being stripped and making electrical contact with the outer lip and conductive housing. Thereby, the wires become electrically interconnected to the conductive housing and to each other.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
277 words
An apparatus for use with a wire having a conductor and an insulating cover over the conductor, said apparatus electrically connecting to the conductor by stripping away a part of the insulating cover and directly contacting the conductor, said apparatus comprising: a housing having an axial opening therein defining an inner surface; first means for stripping the insulating cover and for connecting to the conductor, said first means being attached to the inner surface of the housing; second means for stripping the insulating cover and for connecting to the conductor, said second means being centrally located in the axial opening of the housing and opposing the first means; third means for supporting the wire between the first means and the second means and for moving the wire with respect to the first means and the second means wherein said housing comprises a tubular member having a curved inner surface; wherein said first means comprises an outer annular projection located on the curved inner surface of the tubular member; wherein said second means comprises an axle having an inner annular projection, said axle being concentrically located within the tubular member such that the inner annular projection opposes the outer annular projection; and wherein said third means comprises a cylinder having an aperture for receiving the wire, said cylinder being concentrically located with the tubular member such that the aperture is in registry with the opening formed between the inner and outer annular projections, whereby the first means cooperates with the second means to strip the insulating cover as the wire is moved by the third means, thereby establishing an electrical contact between the conductor and the first means.
Claim 2
Independent Claim
277 words
An apparatus for use with a wire having a conductor and an insulating cover over the conductor, said apparatus electrically connecting to the conductor by stripping away a part of the insulating cover and directly contacting the conductor, said apparatus comprising: a housing having an axial opening therein defining an inner surface; first means for stripping the insulating cover and for connecting to the conductor, said first means being attached to the inner surface of the housing; second means for stripping the insulating cover and for connecting to the conductor, said second means being centrally located in the axial opening of the housing and opposing the first means; third means for supporting the wire between the first means and the second means and for moving the wire with respect to the first means and the second means wherein said housing comprises a tubular member having a curved inner surface; wherein said first means comprises an outer annular projection located on the curved inner surface of the tubular member; wherein said second means comprises an axle having an inner annular projection, said axle being concentrically located within the tubular member such that the inner annular projection opposes the outer annular projection; and wherein said third means comprises a cylinder having an aperture for receiving the wire, said cylinder being concentrically located with the tubular member such that the aperture is in registry with the opening formed between the inner and outer annular projections, whereby the first means cooperates with the second means to strip the insulating cover as the wire is moved by the third means, thereby establishing an electrical contact between the conductor and the first means.
Claim 3
Dependent Claim
63 words
The apparatus of claim 1 wherein said outer annular, conductive projection comprises an outer lip located on and projecting from the curved inner surface of the tubular, conductive member, said outer lip having an inclined surface which forms a slot with the inner annular projection of the axle, whereby the wire may be inserted through the aperture in the cylinder into the slot.
Claim 4
Dependent Claim
16 words
The apparatus of claim 2 wherein said outer lip is helicoidally located on said inner surface.
Claim 5
Dependent Claim
17 words
The apparatus of claim 2 wherein said outer lip comprises upper and lower, oblique and divergent portions.
Claim 6
Dependent Claim
48 words
The apparatus of claim 2 further comprising a second outer lip opposing the inner lip of the axle, whereby the wire may be inserted between the first outer lip and the inner lip and between the second outer lip and the inner lip to provide a dual connection.
Claim 7
Dependent Claim
56 words
The apparatus of claim 2 wherein said cylinder has a second aperture in registry with the opening between said inner and outer lips and wherein the portion of the inner and outer lips in registry with the first aperture is concentrically above the portion of the inner and outer lips in registry with the second aperture.
Claim 8
Dependent Claim
59 words
The apparatus of claim 2 wherein said cylinder includes an annular groove having a split therein such that the groove engages the outer lip and the split is in registry with the aperture in the cylinder whereby inserting the wire in the aperture results in the wire being located in the split and between the inner and outer lips.
Claim 9
Dependent Claim
18 words
The apparatus of claim 7 wherein said cylinder includes left and right apertures, each for receiving a wire.
Claim 10
Dependent Claim
96 words
The apparatus of claim 7 further including a second cylinder located at the end of the tubular member opposite the first cylinder, said second cylinder having a second aperture for receiving the wire; further including a second outer lip located on the curved inner surface and a second inner lip located on the axle opposite the second outer lip, said second inner and outer lips forming a second opening in registry with the second aperture; and wherein each end of said axle is supported within said tubular member by engaging said first and second cylinders, respectively.
