Lamp socket for high wattage lamps
View Patent ↗A zero insertion force socket for a lamp. The lamp socket ( 10 ) for a high wattage lamp ( 12 ) having lamp pins ( 14, 16 ), comprises a substantially solid, parallelepipedonal electrically insulating body ( 18 ), preferably of a ceramic material, having two side walls ( 20, 22 ), two end walls ( 24, 26 ) and a top ( 28 ) and a bottom ( 30 ) with first and second electrical contact receiving sections ( 32, 34 ) formed in the top ( 28 ). First and second contact reception areas ( 34, 36 ), respectively, are formed in each of the first and second electrical contact receiving sections. An electrical contact ( 38 ), is positioned in each of the contact reception areas ( 34, 36 ), and each of the electrical contacts ( 38 ) has a lamp pin receiver ( 40 ) with arms ( 42, 44 ). Means ( 46 ), for example, a threaded member ( 58 ) such as a bolt, is provided for constricting the arms to grasp the lamp pins after insertion into the socket. The threaded member ( 58 ) has a freely-rotatable head ( 58 a ) positioned in arm ( 44 ) and a threaded end ( 58 b ) engaging a threaded aperture ( 58 c ) in arm 42.
1. A lamp socket for a high wattage lamp having lamp pins, said socket comprising:
a substantially solid, parallelepipedonal electrically insulating body having two side walls, two end walls and a top and a bottom with first and second electrical contact receiving sections formed in said top; said insulating body containing means for engaging said socket with a foundation;
first and second contact reception area formed in each of said first and second electrical contact receiving sections;
an electrical contact positioned in each of said contact reception areas, each of said electrical contacts having a lamp pin receiver with a pair of arms;
means comprising a threaded member for constricting said arms to grasp said lamp pins;
a wire-receiving aperture formed in one of said arms of each electrical contact;
means formed in each of said side walls for receiving a wire;
means for securing a wire inserted into said wire receiving aperture formed in said one of said arms;
an air gap formed between said first and second electrical contact receiving sections; and
an aperture formed in each of said side walls for gaining access to said means for constricting said arms.
2. The lamp socket of claim 1 wherein said means for securing said wire in said one of said arms comprises a second treaded member.
3. The lamp socket of claim 1 wherein said electrically insulating body is ceramic.
4. The lamp socket of claim 1 wherein said threaded member is surrounded by a retaining ring.
5. The lamp socket of claim 1 wherein an electrically insulating cover is mounted upon said electrically insulating body, said cover having apertures for receiving said lamp pins.
6. The lamp socket of claim 5 wherein said electrically insulating cover contains apertures for accessing said second threaded member.
