High voltage lamp holder

摘要

A socket body (SB) (11) and a retaining sleeve (RS) (12) use coupling devices to plug into each other, which have a bayonet-locking design, a lifter/cam (17) in the RS pointing radially inwards and a shoulder (21) on the SB for the base (19) of the cam so that the SB and the RS couple up when pushed together and turned.
