Abstract
Abstract An electrical connector has a resilient, stamped, metallic leaf contact defining a narrow neck contact entrance area and having reversely bent ends on either side of said area. A plastic body section embeds the ends and spans the area to provide two side by side lever legs arranged to act so that pressure on the legs resiliently opens the narrow neck to allow entrance of a second body contact. Relaxation of pressure on the legs causes resilient action of the connector to provide gripping of the second contact with a positive three point grip.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
An electrical connector comprising a resilient metallic stamped contact defining a narrow neck reentrant contact area entrance and having extension ends on either side of said area carrying means for engaging a plastic body, a plastic body section embedding said extension ends and providing two side by side legs extending from said area arranged to act as levers so that pressure on said legs resiliently opens said narrow neck to allow entrance of an electrode contact and relaxation of pressure cause resilient spring action of said stamped contact to provide gripping of said electrode, said stamped contact defining wall means carrying three detents positioned so that said resilient action provides positive gripping of said electrode with said electrode urged into engagement with each of said three detents of said resilient contact, said wall means having sections converging towards each other in the direction of said reentrant contact area entrance.
Claim 2
Dependent Claim
149 words
An electrical connector comprising a resilient metallic stamped contact defining a narrow neck reentrant contact area entrance and having extension ends on either side of said area carrying means for engaging a plastic body, a plastic body section embedding said extension ends and providing two side by side legs extending from said area arranged to act as levers so that pressure on said legs resiliently opens said narrow neck to allow entrance of an electrode contact and relaxation of pressure cause resilient spring action of said stamped contact to provide gripping of said electrode, said stamped contact defining wall means carrying three detents positioned so that said resilient action provides positive gripping of said electrode with said electrode urged into engagement with each of said three detents of said resilient contact, said wall means having sections converging towards each other in the direction of said reentrant contact area entrance.
Claim 3
Dependent Claim
18 words
An electrical connector in accordance with claim 1 wherein said stamped contact defines integral opposed reversely bent portions.
Claim 4
Dependent Claim
47 words
An electrical connector in accordance with claim 2 and further comprising, said plastic being a resilient material having a stiffness and resiliency which allows expansion and contraction of said contact area without taking a permanent set, said wall means comprising three wall sections in a trapezoidal arrangement.
Claim 5
Dependent Claim
42 words
An electrical connector in accordance with claim 1 and further comprising, said body section defining a lower surface designed to coact with an electrode assembly to position said detents in a plane for maximized gripping of a rim provided by said electrode.
Claim 6
Dependent Claim
47 words
An electrical connector in accordance with claim 1 and further comprising, said side legs having rear ends, said ends carrying a resilient web extending therebetween and integrally molded therewith acting to prevent entrance therebetween of lead wires which could cause intertangling of said connectors with said wires.
Claim 7
Dependent Claim
127 words
An electrical connector comprising a resilient metallic stamped contact defining a narrow neck contact area entrance and having extension ends on either side of said area carrying means for engaging a plastic body, a plastic body section embedding said extension ends and providing two side by side legs extending from said area arranged to act as levers so that pressure on said legs resiliently opens said narrow neck to allow entrance of an electrode contact and relaxation of pressure cause resilient action of said stamped contact to provide gripping of said electrode, said side legs having ends, said ends carrying a resilient web extending therebetween and integrally molded therewith acting to prevent entrance therebetween of lead wires which could cause intertangling of said connectors with said wires.
Claim 8
Dependent Claim
127 words
An electrical connector comprising a resilient metallic stamped contact defining a narrow neck contact area entrance and having extension ends on either side of said area carrying means for engaging a plastic body, a plastic body section embedding said extension ends and providing two side by side legs extending from said area arranged to act as levers so that pressure on said legs resiliently opens said narrow neck to allow entrance of an electrode contact and relaxation of pressure cause resilient action of said stamped contact to provide gripping of said electrode, said side legs having ends, said ends carrying a resilient web extending therebetween and integrally molded therewith acting to prevent entrance therebetween of lead wires which could cause intertangling of said connectors with said wires.
