Abstract
A lampholder for a medium bi-pin fluorescent lamp has a combination slot permitting either "straight-in" or "turn-lock" insertion. The lampholder contacts have a pin-contacting section supported for reliable resilient gripping of the lamp pins so that the lamps will not drop out accidently, while a planar contact mounting section and use of only one major fold reduce contact cost.
Claims19
A contact for a lampholder consisting of a unitary metal element, having a single mounting portion only and means for making electrical connection with the element;
- a substantially planar section, defining a plane, at least a portion of said planar section being said single mounting portion;
- and a pin-contacting section extending in a longitudinal direction from said substantially planar section toward and past a pin-contacting region;
- wherein said longitudinal direction is parallel to said plane defined by the substantially planar section, and said pin-contacting section is perpendicular to said plane.
A contact for a lampholder, having a single mounting portion only;
- and consisting of a unitary metal element, having a substantially planar section, defining a plane, at least a portion of said planar section being said single mounting portion;
- a pin-contacting section extending in a generally longitudinal direction from said substantially planar section toward and past a pin-contacting region;
- and means for making electrical connection with the elements, said means including at least one pressure connection tongue extending longitudinally from and substantially co-planar with said mounting portion, said longitudinal direction being parallel to said plane defined by the substantially planar section, and said pin-contacting section being perpendicular to said plane.
A lampholder comprising:
- a housing having slot means for accepting lamp pins, including a pair of spaced parallel slots arranged for accepting lamp pins by "straight-in" insertion, and at least one slot intercepting said parallel slot for movement of lamp pins inserted by "turn-lock" insertion;
- and
- a pair of electrical contacts for making electrical contact with respective inserted lamp pins of a bi-pin lamp and for retaining said lamp pins, said contacts each having a single pin-gripping portion only for retaining the inserted lamp pins.
