Abstract
A lamp socket is provided with a body member or shell having an opening in its top and first and second electrical contacts in the shell to make electrical contact with a light bulb inserted into the shell. A tapered, resilient support arm projects inwards from a wall of the shell to engage the bottom face of an inwardly projecting tab portion of one electrical contact, which engages the base of the light bulb. This resilient arm prevents permanent deformation of the tab upon insertion of a light bulb to a greater than average depth into the socket and returns the tab to its initial position after the light bulb is removed. The other contact engages the light bulb ferrule.
Claims4
A light bulb socket assembly comprising:
- a body member having an opening in its top for insertion of a light bulb and an opening at its bottom to accommodate the passage through the body member of a pair of current carrying wires,
- a pair of electrical contacts held within said body member for contact between the current carrying wires and the light bulb, each said contact having a first portion for making contact with the current carrying portion of one of said pair of current carrying wires and a second portion for making contact with a current carrying portion of a light bulb, the second portion of at least one of said electrical contacts including an electrical tab projecting across the interior of the body member for engaging a base terminal of the light bulb;
- and
- relatively resilient cantilevered support means projecting radially inward from a wall of said socket and disposed at a predetermined position below said tab for limiting downward displacement of said tab.
