Abstract
Abstract An insulation displacement terminal for nonmetallic core cable comprises an insulation displacement portion having fore and aft crimp barrels connected by a bridge. The bridge has flat plates integrally connected at opposite sides by bights so that the plates confront each other. The plates have sharp edges for penetrating and slicing through the cable jacket and insulation and elongated dimples which cooperatively form the slot which receives the nonmetallic conductive core of the cable.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
143 words
An insulation displacement terminal for piercing the insulation of an insulated electrical cable and making contact with a nonmetallic conductive core of the cable comprising, an insulation displacement portion having first and second crimp barrels spaced apart longitudinally and connected by an intermediate bridge, first and second plates connected at opposite longitudinal sides of the bridge by respective bights so that the first and second plates are spaced apart and confront each other, and a transversely elongated dimple in each plate which extends toward the dimple of the other plate to cooperatively form a core receiving slot, and each of said plates having a sharp edge at the side opposite the bridge for penetrating and slicing through the insulation of an insulated cable forced down between the plates so that the nonmetallic conductive core enters the slot cooperatively formed by the elongated dimples.
Claim 2
Dependent Claim
143 words
An insulation displacement terminal for piercing the insulation of an insulated electrical cable and making contact with a nonmetallic conductive core of the cable comprising, an insulation displacement portion having first and second crimp barrels spaced apart longitudinally and connected by an intermediate bridge, first and second plates connected at opposite longitudinal sides of the bridge by respective bights so that the first and second plates are spaced apart and confront each other, and a transversely elongated dimple in each plate which extends toward the dimple of the other plate to cooperatively form a core receiving slot, and each of said plates having a sharp edge at the side opposite the bridge for penetrating and slicing through the insulation of an insulated cable forced down between the plates so that the nonmetallic conductive core enters the slot cooperatively formed by the elongated dimples.
Claim 3
Dependent Claim
200 words
An insulation displacement terminal for piercing the insulation of an insulated electrical cable and making contact with a nonmetallic conductive core of the cable comprising, an insulation displacement portion having first and second crimp barrels spaced apart longitudinally and connected by an intermediate bridge, first and second flat plates connected at opposite longitudinal sides of the bridge by respective bights so that the first and second flat plates are spaced apart in a confronting relationship by a distance which is less than the outer diameter of the cable and greater than the diameter of the nonmetallic conductive core, a transversely elongated dimple in each plate which extends toward the dimple of the other plate to cooperatively form a core receiving slot which has a width which is less than the diameter of the nonmetallic conductive core so that the core distorts to an oval shape when it is disposed in the slot, and each of said plates having a sharp convex edge at the side opposite the bridge for penetrating and slicing through the insulation of an insulated cable forced down between the flat plates so that the nonmetallic conductive core enters the slot cooperatively formed by the elongated dimples.
