Abstract
Abstract A device for electrically connecting a pair of main supply wires to a pair of lateral branch wires without stripping insulation from the main wires. A block of insulating material has two parallel grooves which receive the main wires and their insulating covering. Adjacent each main wire is a bore extending radially with respect to the main wire, the bore containing a sharp pointed metallic conducting element. The bore containing the pointed metallic element intersects a lateral bore into which the stripped end of the branch wire is placed. A screw of insulating material bears against the stripped end of the lateral wire, presses it tightly against the butt end of the pointed metallic element and drives the point thereof through the insulation covering of the main wire, to make contact with the metallic conductor therein.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
235 words
An electric wire connector for connecting a branch wire to an insulated main wire without requiring insulation to be prestripped from the main wire, said connector comprising a body having a groove for receiving the main wire with insulation thereon, a first bore spaced from and extending crosswise with respect to said groove, said bore being adapted to receive an end of a branch wire with insulation stripped from a portion thereof, a second bore intersecting said first bore and opening externally of said body and also opening into said groove at a location aligned with a main wire therein, said second bore having screw threads therein, a metallic conductor element located in said second bore between said groove and said first bore, said element having a sharp point at the end thereof toward said groove, and a screw of insulating material located in said second bore on the opposite side of said first bore from said groove, said screw engaging said threads in said second bore, so that when said screw is screwed into said second bore with a stripped portion of a branch wire interposed between said screw and said conductor element, said screw will press said stripped portion tightly against said element and will press the point of said element into and through insulation on a main wire located in said groove to make electric contact with a conductor within said insulation.
Claim 2
Dependent Claim
235 words
An electric wire connector for connecting a branch wire to an insulated main wire without requiring insulation to be prestripped from the main wire, said connector comprising a body having a groove for receiving the main wire with insulation thereon, a first bore spaced from and extending crosswise with respect to said groove, said bore being adapted to receive an end of a branch wire with insulation stripped from a portion thereof, a second bore intersecting said first bore and opening externally of said body and also opening into said groove at a location aligned with a main wire therein, said second bore having screw threads therein, a metallic conductor element located in said second bore between said groove and said first bore, said element having a sharp point at the end thereof toward said groove, and a screw of insulating material located in said second bore on the opposite side of said first bore from said groove, said screw engaging said threads in said second bore, so that when said screw is screwed into said second bore with a stripped portion of a branch wire interposed between said screw and said conductor element, said screw will press said stripped portion tightly against said element and will press the point of said element into and through insulation on a main wire located in said groove to make electric contact with a conductor within said insulation.
Claim 3
Dependent Claim
50 words
A construction as defined in claim 1, wherein said body has two grooves for receiving two main wires extending parallel to each other adjacent opposite sides of the body, and wherein there is a first bore, second bore, conductor element, and screw in separate cooperative relationship to each groove, respectively.
Claim 4
Dependent Claim
14 words
A construction as defined in claim 1, wherein said body is of insulating material.
Claim 5
Dependent Claim
14 words
A construction as defined in claim 1, wherein said body is of molded plastic.
Claim 6
Dependent Claim
14 words
A construction as defined in claim 1, wherein said body is of transparent material.
Claim 7
Dependent Claim
69 words
A construction as defined in claim 1, wherein an outer portion of said first bore is of sufficient diameter to receive a branch wire with normal insulation thereon, and an inner portion of said first bore, in the vicinity of said second bore, is too small to receive a branch wire with normal insulation thereon but will a portion of the branch wire from which insulation has been stripped.
Claim 8
Dependent Claim
43 words
A construction as defined in claim 1, wherein said groove has a depression in which the main wire may become seated so as to resist accidental lateral displacement of the main wire while the point of said element is being forced into it.
