Electric lamp socket assembly having stripless wiring terminals

Claim 2

An electric lamp socket assembly for stripless connection to an electric cord having a hot wire and a neutral wire, said assembly comprised of: a screwshell for holding an electric lamp bulb; at least one inner contact for making electrical contact to said lamp bulb; a body of insulating material having one end supporting said screwshell and contact; at least one pair of insulation piercing terminals projecting from the opposite end of said body, one of said terminals for connection to said hot wire and another terminal for connection to said neutral wire; and a cover arranged in pivotable relation with said body, said cover having means to align said wires with said terminals and adapted to close over said terminals thereby clamping said cord against said body, said means requiring insertion of said wires in the direction of their lengths through an opening of the cover, and including an abutment at the other end thereof located in line with said opening and limiting the extent to which the wires may be inserted.

Claim 3

The electric lamp socket assembly of claim 1 wherein said cover has a yoke for holding said cord and a groove for aligning said cord with said terminals during wiring, said yoke having said opening formed therein and said groove extending fully from the yoke to said abutment, the groove and opening requiring that both wires be in longitudinally contacting relation when inserted through the opening and engaged by the abutment in alignment with the respective terminals.

Claim 4

An electric lamp socket assembly as in claim 1, wherein the pivotable relation of the cover to the body is disposed at one end of the cover and the cover includes means at its other end for fixedly connecting the cover to the body when in its closed position, the cover having an opening at said other end thereof through which the cord is extendable, the body including means for strain relieving the cord in an area thereof between the terminals and said opening of the cover, said body having a flat surface facing toward said cover and cooperating with the cover in clamping the wires therebetween, said terminals projecting above the flat surface so as to require that the wires will be pierced by the terminals when clamped between the cover and said flat surface, said strain-relieving means being formed upon said flat surface and also projecting thereabove to an extent requiring that said strain-relieving means be forced into the wires whenever the wires are pierced by the terminals and are clamped between the cover and body.

Claim 5

An electric lamp socket assembly as in claim 3, wherein the strain-relieving means comprises a series of ridges on the body extending transversely of the path along which the cord extends between the openings and the terminals.

Claim 6

An electric lamp socket assembly as in claim 4 wherein the ridges are integral with the body.

Claim 7

An electric lamp socket assembly for stripless connection to an electric cord having a hot wire and a neutral wire, said assembly comprised of: a screwshell for holding an electric lamp bulb; at least one inner contact for making electrical contact to said lamp bulb; a body of insulating material having one end supporting said screwshell and contact; at least one pair of insulation piercing terminals projecting from the opposite end of said body, one of said terminals for connection to said hot wire and another terminal for connection to said neutral wire; a cover arranged in pivotable relation with said body, said cover having means to align said wires with said terminals and adapted to close over said terminals thereby clamping said cord against said body; a cam on said cover; and a spring arranged to press against said cam and hold said cover in open and closed positions.

Claim 8

An electric lamp socket assembly for stripless connection to an electric cord having a hot wire and a neutral wire, said assembly comprised of: a screwshell for holding an electric lamp bulb; at least one inner contact for making electrical contact to said lamp bulb; a body of insulating material having one end supporting said screwshell and contact; at least one pair of insulation piercing terminals projecting from the opposite end of said body, one of said terminals for connection to said hot wire and another terminal for connection to said neutral wire; a cover arranged in pivotable relation with said body, said cover having means to align said wires with said terminals and adapted to close over said terminals thereby clamping said cord against said body; a cam on said cover; and a spring arranged to press against said cam and hold said cover in open and closed positions.

Claim 9

The electric lamp socket assembly of claim 6 wherein one of said terminals and said spring are parts of one piece of metal.

Claim 10

The electric lamp socket assembly of claim 7 wherein said piece is electrically connected to said screwshell.

Claim 11

The electric lamp socket assembly of claim 7 which further includes a second pair of terminals, one of said second pair of terminals is part of said piece of metal.

Claim 12

The electric lamp socket assembly of claim 9 wherein said piece is electrically connected to said screwshell.

Claim 13

An electric lamp socket assembly for stripless connection to an electric cord having a hot wire and a neutral wire, said assembly comprised of: a screwshell for holding an electric lamp bulb; at least one inner contact for making electrical contact to said lamp bulb; a body of insulating material having one end supporting said screwshell and contact; at least one pair of insulation piercing terminals projecting from the opposite end of said body, one of said terminals for connection to said hot wire and another terminal for connection to said neutral wire; and a cover arranged in pivotable relation with said body, said cover having means to align said wires with said terminals and adapted to close over said terminals thereby clamping said cord against said body, said cover having a recess so that said cord must be step cut for proper insertion, thereby assuring correct polarization of the cord and electrical clearance between the wire ends.

Claim 14

An electric lamp socket assembly for stripless connection to an electric cord having a hot wire and a neutral wire, said assembly comprised of: a screwshell for holding an electric lamp bulb; at least one inner contact for making electrical contact to said lamp bulb; a body of insulating material having one end supporting said screwshell and contact; at least one pair of insulation piercing terminals projecting from the opposite end of said body, one of said terminals for connection to said hot wire and another terminal for connection to said neutral wire; and a cover arranged in pivotable relation with said body, said cover having means to align said wires with said terminals and adapted to close over said terminals thereby clamping said cord against said body, said cover having a recess so that said cord must be step cut for proper insertion, thereby assuring correct polarization of the cord and electrical clearance between the wire ends.

Claim 15

The electric lamp socket assembly of claim 11 wherein said recess is a hole allowing visual check of proper cord insertion.
