Abstract
Abstract The present invention discloses a device for connecting two flat insulated wires. The device includes a body member having an opening therethrough and a wedge member. The sides of the opening have a sharp ridge so that as the wedge squeezes the wires against the sides, the teeth pierce the insulation to make electrical contact.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
114 words
A device for mechanically retaining and electrically interconnecting two insulated wires, comprising: a. a body member of conductive material having an opening with parallel sides therethru with at least one inwardly projecting ridge on each side thereof running the length of the opening, said ridges having a sharp point thereon; and b. a wedge member of conductive material having a beveled front section and a straight rear section and adapted to be driven into the opening of the body member so that the straight rear section squeezes the wires which may be positioned therein against the ridges whereby the sharp points thereon cut thru the insulation and make electrical contact with the underlying conductors.
Claim 2
Independent Claim
114 words
A device for mechanically retaining and electrically interconnecting two insulated wires, comprising: a. a body member of conductive material having an opening with parallel sides therethru with at least one inwardly projecting ridge on each side thereof running the length of the opening, said ridges having a sharp point thereon; and b. a wedge member of conductive material having a beveled front section and a straight rear section and adapted to be driven into the opening of the body member so that the straight rear section squeezes the wires which may be positioned therein against the ridges whereby the sharp points thereon cut thru the insulation and make electrical contact with the underlying conductors.
Claim 3
Dependent Claim
34 words
The device of claim 1 wherein the top and bottom surfaces of the opening converge towards the center thereof so that the opening is narrower in the center portion and larger at either side.
