Abstract
A light bulb socket structure is provided having a waterproof feature. In the socket structure, a resilient skirt of a light bulb holder and an annular flange of a light bulb seat produce a watertight joint, which cooperates with waterproof end cap or plug attached to the lower end of the light bulb seat to provide protection for electrical connection portions of a light bulb installed on the socket against water penetration.
Claims3
A light bulb socket structure having a waterproof feature, comprising a light bulb, a light bulb holder, a light bulb seat, and a watertight end cap, wherein said light bulb holder is coaxially provided with a hole around which there is provided an annular flange on a top portion of said holder, said annular flange being dimensioned to closely embrace an outer periphery of said light bulb for a watertight effect and has an elastic skirt around an outer periphery of said light bulb holder;
- said light bulb seat being provided on a top portion thereof with an engaging shoulder that allows said light bulb holder to be assembled thereon with said engaging shoulder abutting against an underside portion of said skirt to produce a watertight joint and is further provided with a groove on each of two opposite sides of a lower portion thereof;
- and,
- said watertight end cap being capable of receiving the lower portion of said light bulb seat and also has a groove formed on each of two opposite sides thereof corresponding to said grooves on said light bulb seat to provide a passage way for electrical wires to extend therethrough, said end cap having a central portion formed with a joining seat which protrudes into an interior space of said light bulb seat as said end cap is attached to said light bulb seat to secure the electrical wires in position and to achieve a watertight effect.
A light bulb socket structure having a waterproof feature, comprising a light bulb a light bulb holder, a light bulb seat, and a watertight plug, wherein said light bulb holder is coaxially provided with a hole around which there is provided an annular flange on a top portion of said holder, said annular flange being dimensioned to closely embrace an outer periphery of said light bulb for a watertight effect and has an elastic skirt around an outer periphery of said light bulb holder:
- said light bulb seat being provided on its a top portion thereof with an engaging shoulder that allows said light bulb holder to be assembled thereon with said engaging shoulder abutting against an underside portion of said skirt to produce a watertight joint and is further provided with a groove on each of two opposite sides of a lower portion thereof;
- and,
- said watertight plug having a semi-circular groove formed on each of two opposite sides thereof, said watertight plug being insertable into a lower end of said light bulb seat with the semi-circular grooves securing electrical wires connected to the light bulb seat to form a watertight end .
