Abstract
A novel lamp socket finding application with a type of increased protection, has a housing part (13) in which a one-piece elastomer sealing sleeve (20) is preferably rotatably held. The sealing sleeve (20) is at its lamp-side end preferably slightly radially compressible, while it is stiffer in the axial direction. As a result, it yields inward when axially pressed by the frustoconical inner side of the housing part (13). The one-piece construction of the sealing sleeve (20) from a single material, on the one hand, ensures a simple manufacture and, on the other hand, prevents a faulty mounting caused by slipped seals or the like.
Claims7
A lamp socket (1) for a light means, particularly for fluorescent lamps, comprising a socket housing (2) including a stationary first housing part (12) and a second housing part (13) which may be screwed together with the first housing part (12);
- the first and second housing parts (12, 13) enclose an inner space (4) in which a connecting device (5) is accommodated and a throughout one-piece, flexible sealing sleeve (20), the sleeve (20) has a conical basic shape, the sleeve (20) has a narrow end and a wider end, the sleeve (20) has an interior passage (21) surrounded by an interior frustoconical wall (22), the sleeve 20 which at the wider end is provided with an axial sealing face (26) associated with a sealing face (17) of the socket housing (2) and which at the narrow end, the frustoconical wall (22) has a face portion which is provided with a radial sealing face (25) which is associated with the light means, the sleeve (20) includes longitudinal elements (30, 31, 32, 33, 34) for stiffening the seal sleeve (20) in the longitudinal direction, the sealing sleeve (20) is provided with a projection (28) at its outer circumference, the projection 28 is associated with the longitudinal elements (30, 31, 32, 33, 34) for stiffening the seal sleeve (20) in the longitudinal direction;
- wherein the sealing sleeve is provided at both ends with at least one respective annular rib;
- wherein the projection is a radial flange;
- wherein the second housing part includes an inward facing rib which is in engagement with the radial flange.
