Abstract
Abstract An electrical wire connection in which an electrically conductive connector element in an insulating body makes electrical connection to the conductor of an insulated wire. The connector element has an open-ended hollow cylindrical wire connecting end formed with a pair of opposed V-shaped wire entrance areas leading into straight sided wire connecting slots and the wire is more deeply inserted into one slot than the other.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
An electrical wire connection comprising: an insulating connector body having a receptacle for a connector element, an electrically conductive connector element within said receptacle, said element having an open-ended hollow cylindrical wire connecting end formed with a pair of identical opposed V-shaped wire entrance areas extending from the open end of said wire connecting end and leading into identical straight sided wire connecting slots running parallel to the axis of said wire connecting end, an insulated electrical wire inserted into said wire connecting slots, said wire being inserted deeper into one slot than the other, having its insulation cut and the conductor thereof more deeply indented by the edges of said slot into which it is more deeply inserted and terminating a short distance outside of said connector element on the side thereof where it is more deeply inserted into said slot.
Claim 2
Dependent Claim
142 words
An electrical wire connection comprising: an insulating connector body having a receptacle for a connector element, an electrically conductive connector element within said receptacle, said element having an open-ended hollow cylindrical wire connecting end formed with a pair of identical opposed V-shaped wire entrance areas extending from the open end of said wire connecting end and leading into identical straight sided wire connecting slots running parallel to the axis of said wire connecting end, an insulated electrical wire inserted into said wire connecting slots, said wire being inserted deeper into one slot than the other, having its insulation cut and the conductor thereof more deeply indented by the edges of said slot into which it is more deeply inserted and terminating a short distance outside of said connector element on the side thereof where it is more deeply inserted into said slot.
Claim 3
Dependent Claim
54 words
The connection of claim 1 wherein said connector element receptacle extends into a generally planar surface of said insulating body, said connector element slots extend to both sides of the plane of said planar surface and said wire on said side more deeply inserted is inserted substantially to the plane of said planar surface.
Claim 4
Dependent Claim
32 words
The connection of claim 2 wherein said insulating body includes portions extending from said planar surface thereof to surround said wire connecting end except along a line through said wire connecting slots.
Claim 5
Dependent Claim
20 words
The connection of claim 1, 2 or 3 wherein said connector element is formed of No. 360 free cutting brass.
Claim 6
Dependent Claim
26 words
The connection of claim 4 wherein the end of said connector element opposite said wire connecting end is formed with an axially extending screw threaded bore.
Claim 7
Dependent Claim
37 words
The connection of claim 5 wherein said connector element includes a body portion between said connecting end and said opposite end, said body having a polygonal cross-section, and wherein said insulating body closely surrounds said body portion.
Claim 8
Dependent Claim
44 words
The connection of claim 1 wherein in said slot into which said wire is inserted the lesser depth it is inserted to a depth such that its insulation is generally flush with the base of said V-shaped wire entrance area leading into said slot.
