Abstract
Abstract The body of the socket is made from a plastic material having a degree of resiliency in a manner to receive and support a pair of terminals located within a recess in which the base of a lamp bulb is insertable. An extension on each terminal projects into the body of the socket and is provided with barbs into which the wires of a pair of conductors are forced by a plug which urges the conductors apart as the plug is anchored within the body. The exterior of the body has securing means which supports the socket in an aperture in a lamp housing or other supporting member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
150 words
In a socket, a body having a recess at one end for supporting a base of a lamp bulb in engagement with a contact, a conducting strip extending from said contact into the end of the socket opposite to that having the lamp bulb receiving recess, said strip having barbs extending therefrom and projecting inwardly of the body, a plug having anchoring means thereon insertable in said opposite end and of a dimension to engage and force the end sections of a pair of insulated wire conductors toward said strip and the insulation of said conductors over said barbs sufficiently to cause said wire conductors to move into conducting relation with said barbs, and anchoring means within the socket engageable with the anchoring means on the plug for locking the plug in firm fixed relation therein and the end sections of the wire conductors in conducting relation with the barbs.
Claim 2
Dependent Claim
150 words
In a socket, a body having a recess at one end for supporting a base of a lamp bulb in engagement with a contact, a conducting strip extending from said contact into the end of the socket opposite to that having the lamp bulb receiving recess, said strip having barbs extending therefrom and projecting inwardly of the body, a plug having anchoring means thereon insertable in said opposite end and of a dimension to engage and force the end sections of a pair of insulated wire conductors toward said strip and the insulation of said conductors over said barbs sufficiently to cause said wire conductors to move into conducting relation with said barbs, and anchoring means within the socket engageable with the anchoring means on the plug for locking the plug in firm fixed relation therein and the end sections of the wire conductors in conducting relation with the barbs.
Claim 3
Dependent Claim
88 words
In a socket as recited in claim 1, wherein a pair of spaced contacts are disposed within the bulb receiving recess having conducting strips extending downwardly therefrom into said opposite end of the socket with the barbs thereon presenting inwardly toward each other, and wherein said plug is insertable between said strips and the end sections of the pair of insulated wire conductors for forcing the conductors toward the strips and onto said barbs which pass through the insulation and engage the end sections of the wire conductors.
Claim 4
Dependent Claim
31 words
In a socket as recited in claim 2, wherein the insulated wire conductors on opposite sides of the locking plug secure the conducting strips in fixed relation within the socket body.
Claim 5
Dependent Claim
50 words
In a socket as recited in claim 2, wherein the body portion is made of plastic material having an annular flange adjacent to the end having the lamp bulb receiving recess, and four securing projections molded with the body portion and located above said annular flange providing a slot therebetween.
