Abstract
Abstract A quick connect electrical wire connector having a housing assembly with a base portion and a closure portion. The housing assembly receives an insulated electrical wire which is not stripped. The base portion is connected to another electrical member. A slicing mechanism is defined between the base portion and the closure portion for transversely slicing through the insulation so as to make electrical contact with the wire core therebeneath. Appropriate connection is provided for electrically connecting the slicing mechanism with the other electrical member. In this manner, closure of the closure portion onto the base portion permits electrical connection between the insulated electrical wire and the other electrical member. The device is provided with an adjustable mechanism so as to be able to accommodate wires of different gauge size with suitable adjustment being made to the device in order to accommodate such different gauge size wires.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
135 words
An electrical terminal block, comprising a base portion having a lower receiving wall for receiving a layer of metal foil material thereon, a metal retaining member havng one wall section engaging the foil material and another wall section, at least one elongated notch formed into said another wall section from a free end thereof defining an opposing pair of cutting edges, and a substantially rectangular member having at least one wire receiving bore formed therethrough and aligned with said elongated notch, whereupon the insertion of the insulated electrical wire into said receiving bore and with the sliding of said metal retaining member onto said base portion, said wire and said elongated notch are forced into engagement to slice the insulation and contact the wire core to electrically interconnect the wire core to the foil material.
Claim 2
Dependent Claim
135 words
An electrical terminal block, comprising a base portion having a lower receiving wall for receiving a layer of metal foil material thereon, a metal retaining member havng one wall section engaging the foil material and another wall section, at least one elongated notch formed into said another wall section from a free end thereof defining an opposing pair of cutting edges, and a substantially rectangular member having at least one wire receiving bore formed therethrough and aligned with said elongated notch, whereupon the insertion of the insulated electrical wire into said receiving bore and with the sliding of said metal retaining member onto said base portion, said wire and said elongated notch are forced into engagement to slice the insulation and contact the wire core to electrically interconnect the wire core to the foil material.
Claim 3
Dependent Claim
102 words
An electrical terminal block as in claim 1, wherein said base portion further comprises an opposing pair of raised shoulders on either side of said lower receiving wall, an undercut formed on the inside lower edge of each shoulder, said undercuts forming a guideway for receiving a wall section of said retaining member, receiving wells formed adjacent the rear edge of each shoulder, means for clamping said retaining member onto said base portion including means for respectively engaging said shoulders, and a projecting finger on each arm for respectively engaging said receiving wells, to lock said retaining member onto said base portion.
Claim 4
Dependent Claim
95 words
An electrical terminal block as in claim 1 wherein said another wall section comprises a pair of parallel elongated notches each having a different width, the width of each being slightly less than the diameter of the wire core of a wire size to be accommodated by that respective notch, and at least one wire receiving bore formed through said substantially rectangular member and aligned respectively with each elongated notch the diameter of each bore substantially corresponding to the diameter of the insulated wire whose wire size is to be accommodated by that respective notch.
Claim 5
Dependent Claim
127 words
An electrical terminal block, comprising a base portion having a lower receiving wall for receiving a layer of metal foil material thereon, a metal retaining member haivng a pair of hingedly interconnected legs, a first leg overlying the metal foil material, a well formed into the lower receiving wall and an aligned aperture in the first leg, said second leg supporting a depending bifurcated slicing tongue, said slicing tongue entering said aligned aperture and well upon closing of said second leg onto said first leg, entry means for insertion of an electrical insulated wire between said first and second legs, whereupon insulation of the wire is sliced by closure of the second leg onto the first leg to thereby interconnect the wire core to the metal foil.
Claim 6
Dependent Claim
127 words
An electrical terminal block, comprising a base portion having a lower receiving wall for receiving a layer of metal foil material thereon, a metal retaining member haivng a pair of hingedly interconnected legs, a first leg overlying the metal foil material, a well formed into the lower receiving wall and an aligned aperture in the first leg, said second leg supporting a depending bifurcated slicing tongue, said slicing tongue entering said aligned aperture and well upon closing of said second leg onto said first leg, entry means for insertion of an electrical insulated wire between said first and second legs, whereupon insulation of the wire is sliced by closure of the second leg onto the first leg to thereby interconnect the wire core to the metal foil.
Claim 7
Dependent Claim
22 words
An electrical terminal block as in claim 4, wherein said slicing tongue is struck from the second leg of said retaining means.
Claim 8
Dependent Claim
46 words
An electrical terminal block as in claim 4, and further comprising a series of spaced locking slits on said base portion, and mating locking fingers to the distal end of said second leg for selectively locking into said locking slits thereby accommodating wires of different sizes.
Claim 9
Dependent Claim
47 words
An electrical terminal block as in claim 6, and further comprising a pair of channels spaced on either side of the receiving wall, and a pair of laterally extending feet on said first leg for fitting into said channels to secure said retaining member secured in place.
