Abstract
Abstract A lamp socket assembly adapted for use with a printed circuit. The lamp socket assembly of the invention includes a tubular socket portion which receives and retains the lamp and which also is attached to a base member in a conventional manner. The tubular socket portion also includes a plurality of longitudinal flanges which cooperate with corresponding notches in an aperture in the printed circuit board to allow the socket to be locked onto the printed circuit board by inserting it and twisting it. The novel feature of a lamp socket in accordance with the invention lies in the inclusion of a resilient ring around the tubular socket portion which provides a biasing force to urge the socket away from the printed circuit board so that the frictional engagement of the flanges and the printed circuit holds it in place.

Claim 1
Independent Claim
232 words
A lamp socket assembly adapted to be mounted on one side of a printed circuit with a tubular portion thereof extending through a notched aperture in said printed circuit, which comprises: a tubular socket portion adapted to receive a light bulb having a filament and means for making electrical connections to said filament; a base member adapted to be latched to said socket portion; a plurality of longitudinal flanges on the outside of said tubular socket portion to be inserted into said aperture and twisted to lock said socket assembly on said printed circuit board; a first unitary electric terminal located in said socket assembly, said first electric terminal including a bulb contacting portion extending into said tubular socket portion and a second portion extending outwardly from said socket portion and adapted to make electrical contact to a first conductor on said printed circuit board; a second unitary electrical terminal located in said socket assembly, said second electrical terminal including a bulb contacting portion extending into said tubular socket portion and a second portion extending outwardly from said socket portion and adapted to make electrical contact to a second conductor on said printed circuit board; said first and second unitary electrical terminals being mounted upon said tubular socket portion independently of said base portion; and integral biasing means on said socket portion for urging said socket assembly away from its locked position.
Claim 2
Dependent Claim
232 words
A lamp socket assembly adapted to be mounted on one side of a printed circuit with a tubular portion thereof extending through a notched aperture in said printed circuit, which comprises: a tubular socket portion adapted to receive a light bulb having a filament and means for making electrical connections to said filament; a base member adapted to be latched to said socket portion; a plurality of longitudinal flanges on the outside of said tubular socket portion to be inserted into said aperture and twisted to lock said socket assembly on said printed circuit board; a first unitary electric terminal located in said socket assembly, said first electric terminal including a bulb contacting portion extending into said tubular socket portion and a second portion extending outwardly from said socket portion and adapted to make electrical contact to a first conductor on said printed circuit board; a second unitary electrical terminal located in said socket assembly, said second electrical terminal including a bulb contacting portion extending into said tubular socket portion and a second portion extending outwardly from said socket portion and adapted to make electrical contact to a second conductor on said printed circuit board; said first and second unitary electrical terminals being mounted upon said tubular socket portion independently of said base portion; and integral biasing means on said socket portion for urging said socket assembly away from its locked position.
Claim 3
Dependent Claim
144 words
A lamp socket assembly adapted to be mounted on one side of a printed circuit with a tubular socket receiving portion extending axially through an aperture in said printed circuit board, which comprises: a tubular socket forming portion; first electrical terminal means retained on said tubular socket receiving portion for making electrical contact to a first contact on a lamp bulb located in said socket; second electrical terminal means retained on said tubular socket receiving portion for making electrical contact to a second contact on said lamp bulb located in said socket; said first and second electrical terminal means each including means for making electrical contact to a conductor on said printed circuit board; a base member attached to said tubular socket portion; and said first and second electrical terminal means being retained on said tubular socket forming portion independently of said base member.
Claim 4
Dependent Claim
144 words
A lamp socket assembly adapted to be mounted on one side of a printed circuit with a tubular socket receiving portion extending axially through an aperture in said printed circuit board, which comprises: a tubular socket forming portion; first electrical terminal means retained on said tubular socket receiving portion for making electrical contact to a first contact on a lamp bulb located in said socket; second electrical terminal means retained on said tubular socket receiving portion for making electrical contact to a second contact on said lamp bulb located in said socket; said first and second electrical terminal means each including means for making electrical contact to a conductor on said printed circuit board; a base member attached to said tubular socket portion; and said first and second electrical terminal means being retained on said tubular socket forming portion independently of said base member.
