ABSTRACT:
An electric bulb holder for supporting a bulb in an apertured panel includes a moulded plastic housing, a contact strip for effecting electrical contact with a bulb seated in the housing and a sheet metal stamping mounted on the housing. The housing includes smaller and larger diameter parts joined by a transverse wall, a locating rim for guiding the housing into the panel aperture and a skirt for effecting a seal about the panel aperture. The sheet metal stamping includes a retaining ring which is fixedly seated on the transverse wall of the housing, a plurality of bayonet-type bulb retaining tangs extending from the ring into the smaller diameter part of the housing, a blade-type electrical terminal extending through a slot in the transverse wall of the housing and lying alongside the outer wall of the smaller diameter part of the housing, and a plurality of mounting wings having leading end parts for retaining the bulb holder in assembly with the panel responsive to axial insertion of the locating rim into the panel aperture and rotation of the holder relative to the panel. The mounting wings also include trailing end parts cooperable with edges of the panel aperture to inhibit accidental counterrotation of the holder relative to the panel.
