Abstract
An assembly for mounting an electric lamp bulb of the type adapted to mate with a bayonet coupling. The assembly includes a one-piece housing of insulating material that completely surrounds a portion of the bulb base. For insulation of the bulb from vibration and to reduce the likelihood of corrosion, metal to metal contact involving the bulb is minimized. A biasing force provided by the resilient deformation of the housing material is used to provide electrical contact between an electrical lead and a bulb base terminal despite the fact that the housing material is semi-rigid.
Claims7
An electric lamp assembly for mounting an electrical bulb having a globe, a cylindrical base, a base terminal insulated from said base and a pair of studs extending radially from said base, said assembly including:
- an insulating housing formed from semi-rigid material and having a base portion and a sleeve portion interconnected with said base portion, said sleeve adapted to receive telescopically said cylindrical base and completely surround a portion of said base in closely contiguous relationship thereto, said sleeve having a pair of longitudinal slots formed therein, each of said slots adapted to receive one of said studs, a first electrical conductor positioned in one end of said sleeve by resilient means integral with said housing, said electrical conductor adapted to be urged into contact with said base terminal by said resilient means, said first conductor adapted to be interconnected with a source of electrical energy, a second electrical conductor at least partially surrounding said sleeve and including a pair of projections, each of said projections extending into one of said slots and engaging only one of said studs, and electrically conductive fastener means securing said second conductor to said base portion and adapted to interconnect said second conductor to an electrically grounded element.
An electric lamp assembly for mounting an electric bulb having a globe, a cylindrical base, a base terminal insulated from said base and a pair of studs extending radially from said base, said assembly including:
- an insulating one-piece housing formed from semi-rigid material, a light transmitting lens removably secured to said housing and defining therewith an enclosed space, a cylindrical sleeve integral with said housing and located within said space, said sleeve adapted to receive and completely surround a portion of said base, said sleeve having a pair of longitudinal slots formed therein adapted to receive said studs, a first electrical conductor positioned in one end of said sleeve and adapted to be urged by resilient means integral with said housing into abuttment with said base terminal, said resilient means comprising a sleeve end wall integral with said housing and having a domed configuration extending into said sleeve, plural aperture means formed through said end wall and weakening the resistance to deformation of said material such that said end wall is resiliently deformable, and conductive latching means positioned in said slots and adapted to engage only said studs upon said bulb base being received in said sleeve a distance sufficient to cause resilient deformation of said end wall, said latching means being secured to said housing and adapted for electrical connection to ground.
