Abstract

1418000 Lamp caps LAMP CAPS Ltd 9 Nov 1973 [13 Nov 1972] 52226/72 Heading H2E An electric lamp cap has a metal shell 1 with two projections 4 which define recesses 2, thus increasing the distance between contacts 9 and shell 1 to reduce tracking. The projections carry bayonet pins 3 and may be turned over at 7 to retain the contact carrying insulating button 5 which may have a central rib 11. The pins 3 may have heads on the inner side of the projections which are accommodated in slots in the insulating button.
