Abstract
Abstract The disclosure relates to a lamp socket having an improved core that facilitates assembly and improved contact of the light bulb with the terminals of the socket. The core is generally cylindrical in shape and has one or more passageways therein adapted to accept and retain complimentary spade terminals. A spring is positioned around the core in the socket housing to provide the necessary lost motion to maintain contact pressure. Locking tabs prevent separation of the core from the housing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
146 words
A lamp socket comprising a socket housing, a core member made of two like sections insertable into said housing in one direction and having at least one passageway in each section, said housing being adapted to accept a light bulb in said one direction, said bulb having two contacts, a pair of relatively thin flat rectangular terminals, each having a laterally extending end face and an aperture therethrough spaced from said end face, said terminals being directly attached to electrical conductors, respectively, said terminals adapted to be inserted in the passageway of each section of said core member in a direction opposite to said one direction with the end faces thereof extending beyond said core member in lamp contact engaging position, and a locking tab within each said core member section extending into the aperture of the terminal therein for securing said terminals within said passageways.
Claim 2
Dependent Claim
146 words
A lamp socket comprising a socket housing, a core member made of two like sections insertable into said housing in one direction and having at least one passageway in each section, said housing being adapted to accept a light bulb in said one direction, said bulb having two contacts, a pair of relatively thin flat rectangular terminals, each having a laterally extending end face and an aperture therethrough spaced from said end face, said terminals being directly attached to electrical conductors, respectively, said terminals adapted to be inserted in the passageway of each section of said core member in a direction opposite to said one direction with the end faces thereof extending beyond said core member in lamp contact engaging position, and a locking tab within each said core member section extending into the aperture of the terminal therein for securing said terminals within said passageways.
Claim 3
Dependent Claim
46 words
The lamp socket described in claim 1 further comprising edge means on said flat end faces located beyond the core member for scraping and cleaning the contacts on said light bulb when said light bulb is inserted into said housing and rotated relative to said terminals.
Claim 4
Dependent Claim
27 words
The lamp socket described in claim 1 further comprising coiled spring means surrounding the two like parts of said core member to retain them in unit relation.
Claim 5
Dependent Claim
50 words
The lamp socket described in claim 3 further comprising a flange on said core member, said spring means being positioned between said flange and said housing for encompassing said two core member sections and providing a lost motion connection to maintain contact pressure between the lamp contacts and spade terminals.
