Abstract
Abstract Contact members within a housing of a fluorescent lampholder are provided with a mounting portion secured in fixed position between the front and back members of the housing and a pincontacting portion that is flat and parallel with a housing wall and not subject to twisting, the pin-contacting portion extending across a frontal opening for engaging an inserted lamp pin. The contact member has resilient means for permitting lateral motion parallel to the front wall but is constrained from any appreciable motion perpendicular to the front wall.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
204 words
An electrical receptacle particularly suitable for receiving a lamp, such as a fluorescent lamp, having a pair of contact pins extending from an end thereof for connection with an electrical supply, said receptacle comprising: a housing including a front body member and a back cover member; said front body member having a front wall with an opening therein to receive contact pins, side walls extending rearwardly from said front wall, a central spacer extending rearwardly from said front wall located between and spaced from said side walls to define a pair of recesses; said back cover member having a plurality of frontwardly extending projections including contact pin locating projections extending within said opening in said front wall, contact member securing projections extending within said recesses and contact member restricting projections extending near said front wall adjacent said opening; a pair of contact members, one in each of said recesses, and having a pincontacting portion extending across said opening for holding a pin contact between an edge of said contact member and said contact pin locating projection; said pin-contacting portion being flat and parallel with said front wall and prevented from twisting out of parallelism by said contact member restricting projections of said back cover.
Claim 2
Dependent Claim
204 words
An electrical receptacle particularly suitable for receiving a lamp, such as a fluorescent lamp, having a pair of contact pins extending from an end thereof for connection with an electrical supply, said receptacle comprising: a housing including a front body member and a back cover member; said front body member having a front wall with an opening therein to receive contact pins, side walls extending rearwardly from said front wall, a central spacer extending rearwardly from said front wall located between and spaced from said side walls to define a pair of recesses; said back cover member having a plurality of frontwardly extending projections including contact pin locating projections extending within said opening in said front wall, contact member securing projections extending within said recesses and contact member restricting projections extending near said front wall adjacent said opening; a pair of contact members, one in each of said recesses, and having a pincontacting portion extending across said opening for holding a pin contact between an edge of said contact member and said contact pin locating projection; said pin-contacting portion being flat and parallel with said front wall and prevented from twisting out of parallelism by said contact member restricting projections of said back cover.
Claim 3
Dependent Claim
49 words
The subject matter of claim 1 further comprising: a base integral with said front body member; a portion of said base extending frontwardly from said front wall with apertures therein for receiving electrical conductors; said contact members having means to make pressure contact to conductors passed through said apertures.
Claim 4
Dependent Claim
43 words
The subject matter of claim 1 wherein: each said contact member has a U-shaped portion held between said front wall and said contact member securing projections of said back cover, and said pin-contacting portion extends perpendicularly from one leg of said U-shaped portion.
Claim 5
Dependent Claim
122 words
A lampholder comprising: a housing having a front member and a back member, said front member having a wall with an opening therein for admitting a lamp pin; a contact member positioned in said housing and having a mounting portion fixedly secured thereto by pressure between said front and back members, said contact member also having a pin-contacting portion that is flat and parallel with said housing wall and partially obstructs said opening with an edge thereacross for engaging an inserted lamp pin, said pin-contacting portion being positioned so that an inserted lamp pin laterally displaces said pin-contacting portion in a direction parallel to said wall, said contact member also having a resilient portion between said mounting portion and said pin-contacting portion.
Claim 6
Dependent Claim
122 words
A lampholder comprising: a housing having a front member and a back member, said front member having a wall with an opening therein for admitting a lamp pin; a contact member positioned in said housing and having a mounting portion fixedly secured thereto by pressure between said front and back members, said contact member also having a pin-contacting portion that is flat and parallel with said housing wall and partially obstructs said opening with an edge thereacross for engaging an inserted lamp pin, said pin-contacting portion being positioned so that an inserted lamp pin laterally displaces said pin-contacting portion in a direction parallel to said wall, said contact member also having a resilient portion between said mounting portion and said pin-contacting portion.
Claim 7
Dependent Claim
40 words
The subject matter of claim 4 further comprising: means within said housing to prevent deflection of said pin-contacting portion in a direction perpendicular to said wall and to prevent twisting of said pin-contacting portion out of parallelism with said wall.
