Lamp socket used in road vehicle - has contact formed as split metal sleeve having notches and fitting into insulator

摘要

The lamp socket has a metal sleeve (11) defining a first contact and containing a hollow insulator (14) and a second contact (17) mechanically and electrically coupled to a supply lead (18). The insulator has an opening into which the second contact is introduced and it can be pushed inwards relative to the metal sleeve against a coil spring when a lamp is inserted in the socket. The second contact (17) comprises a sleeve which is split longitudinally so that it can be compressed to reduce its dia. during its insertion into the opening in the insulator. Notches (19) around the surface of the sleeve prevent its engagement.
