Abstract
Abstract This invention is directed to a terminal formed from a sheet metal blank and adapted to terminate an insulated wire, where said blank is formed into a housing having a cavity therein as defined by a first opening for receiving said insulated wire, and a second opening through which said wire projects. Attached to said housing at said second opening is a crimping member pivotal from an open to a closed position. The crimping member is characterized by a V-shaped slot having downwardly diverging sharp edge portions for cutting the insulation about said wire. Electrical contact with said wire and pivotal action of said crimping member is effected by the movement of the insulated wire into said first opening to project out of said second opening, followed by a limited reverse movement or withdrawal thereof.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
101 words
A wire trap terminal for terminating an insulated electrical wire, where said terminal is provided with leads projecting therefrom for connection to an electrical circuit, said terminal comprising: a housing having a cavity therein as defined by a first opening for receiving an insulated wire, and a second opening through which said wire projects, a crimping member pivotal from an open to a closed position and attached to said housing at said second opening, where said member is provided with a V-shaped slot capable of cutting said insulation, and means for locking said crimping member against movement in said closed position.
Claim 2
Dependent Claim
101 words
A wire trap terminal for terminating an insulated electrical wire, where said terminal is provided with leads projecting therefrom for connection to an electrical circuit, said terminal comprising: a housing having a cavity therein as defined by a first opening for receiving an insulated wire, and a second opening through which said wire projects, a crimping member pivotal from an open to a closed position and attached to said housing at said second opening, where said member is provided with a V-shaped slot capable of cutting said insulation, and means for locking said crimping member against movement in said closed position.
Claim 3
Dependent Claim
29 words
The wire trap terminal according to claim 1 wherein in the closed position said insulation has been cut sufficiently to bring said slot into electrical contact with said wire.
Claim 4
Dependent Claim
42 words
The wire trap terminal according to claim 1 wherein said housing is characterized by a pair of side walls, each having a slot therein, and that said locking means comprises opposing tab projections on said crimping member for engagement with said slots.
Claim 5
Dependent Claim
34 words
The wire trap terminal according to claim 2 wherein the force to pivot said crimping member is derived by the movement of said insulated wire into said housing followed by the limited withdrawal thereof.
Claim 6
Dependent Claim
18 words
The wire trap terminal according to claim 3 including an insulated cover adapted to substantially enclose said housing.
Claim 7
Dependent Claim
22 words
The wire trap terminal according to claim 5 wherein tab means are provided on said cover for engagement with said housing slots.
Claim 8
Dependent Claim
19 words
The wire trap terminal according to claim 1 wherein said housing is stamped from a flat sheet of metal.
