Abstract
Abstract This invention relates to a stamped and formed generally Ushaped electrical terminal useful for terminating magnet or electromagnetic coil wire. More particularly this invention provides a U-shaped terminal stamped and formed from a conductive material wherein a leg has a slot or an opening and a shank which contains a locking tab extending normal thereto such that the locking tab may protrude through the slot or opening and be bent against the leg so as to bias that leg against the shank. The inside surface of the shank leg may contain a plurality of elongated pyramidal shaped teeth or groups of such teeth. When a wire is passed between the shank and leg and both are closed and locked one against the other via the locking tab, the teeth bite through the insulation and into the conductor making electrical contact therewith.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
An electrical terminal for electrical wire, which comprises: a. an elongated shank having a plurality of parallel, elongated teeth extending axially along one surface with each tooth being progressively different in height relative to the next tooth, and the shank further having an elongated tab extending generally upwardly from the one surface; b. an elongated leg positioned movably over the shank and hinged thereto, said leg having an opening therein with said tab extending therethrough so that as the tab is bent against the leg and toward the shank, the leg approaChes the one surface of the shank and pushes an electrical wire which may be lying across the shank into electrical and mechanical engagement with the teeth.
Claim 2
Dependent Claim
118 words
An electrical terminal for electrical wire, which comprises: a. an elongated shank having a plurality of parallel, elongated teeth extending axially along one surface with each tooth being progressively different in height relative to the next tooth, and the shank further having an elongated tab extending generally upwardly from the one surface; b. an elongated leg positioned movably over the shank and hinged thereto, said leg having an opening therein with said tab extending therethrough so that as the tab is bent against the leg and toward the shank, the leg approaChes the one surface of the shank and pushes an electrical wire which may be lying across the shank into electrical and mechanical engagement with the teeth.
Claim 3
Dependent Claim
52 words
The electrical terminal of claim 1 with a longitudinal portion of the leg being convex with respect to the one surface of the shank, said convex portion adapted to roll onto an electrical wire which may be present between the shank and leg when the leg is moved toward the one surface.
Claim 4
Dependent Claim
44 words
The electrical terminal of claim 1 wherein said opening is a slot extending from the leg to the shank with the locking tab being the material stamped out in forming the slot, the locking tab being integrally connected at one end to the shank.
Claim 5
Dependent Claim
123 words
An electrical terminal for electrical wire, which comprises: a. a generally curved hinge member; b. an elongated leg attached to one end of the hinge member; c. a shank attached to another end of the hinge member and positioned in parallel, aligned relation to the leg; d. a slot extending from the leg to the shank; e. a tab, formed from the material provided from stamping out the slot, said tab being integrally connected to the shank and extending through the slot in the leg, said tab being adapted to be bent so that the leg is pressed toward the shank thereby squeezing an electrical wire which may be present inbetween and further with the bent tab locking the leg and shank together.
Claim 6
Dependent Claim
123 words
An electrical terminal for electrical wire, which comprises: a. a generally curved hinge member; b. an elongated leg attached to one end of the hinge member; c. a shank attached to another end of the hinge member and positioned in parallel, aligned relation to the leg; d. a slot extending from the leg to the shank; e. a tab, formed from the material provided from stamping out the slot, said tab being integrally connected to the shank and extending through the slot in the leg, said tab being adapted to be bent so that the leg is pressed toward the shank thereby squeezing an electrical wire which may be present inbetween and further with the bent tab locking the leg and shank together.
Claim 7
Dependent Claim
43 words
The electrical terminal of claim 4 wherein a portion of the leg is concave with respect to the shank so that as the leg is pressed toward the shank, the concave portion rolls onto an electrical wire which may be present therein between.
Claim 8
Dependent Claim
44 words
The electrical terminal of claim 4 further including a set of elongated teeth positioned on the surface of the shank facing the leg, said set consisting of a plurality of teeth each of which is of a progressively different height relative to its neighbor.
