Abstract
Abstract An article of manufacture for the rapid connection of insulated conductive wires without requiring previous preparation or stripping of the insulation to bare of the wires, the wires being clamped between a hollow metal cylinder and a piston slidable in the hollow metal cylinder; the hollow metal cylinder being formed with a radial slot extending substantially over half its diameter and this slot receiving the wires to be connected. The piston is moved to bend the wires and simultaneously tear the insulation thereof and thereby bring the wires into contact with one another. A hollow plastic cylinder surrounds the back portion of the cylinder and the piston and serves as insulation for the connection.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
192 words
An article of manufacture for quick interconnection of two insulated electrical conductors comprising: a. a first hollow insulating plastic cylinder; b. a second metallic hollow cylinder smaller in diameter than the first cylinder and formed with a radial slot over about half of the diameter, said second cylinder being frictionally retained and lying partly within the first cylinder to expose said radial slot; c. a metallic piston having a large-diameter part and a smalldIameter part, said large-diameter part being frictionally retained and sliding within said second hollow cylinder with the small-diameter part projecting toward the radial slot of said second cylinder when making the connection to thereby bend and strip the conductors; d. the slot of said second cylinder being adapted to receive two insulated electrical conductors next to each other so that, upon applying pressure to move said piston within said second cylinder, the top of the smaller diameter part is brought against the two wires and bends the wires at right angles relative to the remaining lengths of said two wires behind the bent portions, said bending forming a rectangular and triangular-shaped crimp in the wire while tearing the insulation.

Claim 3
Dependent Claim
82 words
An article of manufacture as claimed in claim 1, wherein a plurality of first hollow plastic cylinders are provided, each with a web interconnecting one plastic cylinder to an adjacent plastic cylinder so that each of the smaller metallic hollow cylinders with radial slot and frictionally fitting metallic piston may be used to strip, bend, connect and lock the ends of the connectors by movement of the piston within the cylinder and so that the plastic cylinder is broken at the web.
