Abstract

A light emitted diode (LED) light bulb holder used for LED type Christmas light bulb strings comprise specially designed terminals that are used in conjunction with an insertion element to effectively hold leads of a light emitted diode and to firmly connect the LED light bulb with the holder. Thus the insertion element, the terminals and electrical wires seated in a holder body can provide an excellent effect of connecting LED light bulbs with electrical wires.

Claims

1. An improved LED light bulb holder structure comprising a holder body accommodating an insertion element and a pair of terminals associated with electrical wires as well as receiving a LED light bulb on the top thereof, wherein said LED light bulb is furnished on the cylindrical surface of the lower portion thereof with an annular groove or bump that is engaged with a corresponding annular flange or groove formed on the inner wall surface of said holder body;

said insertion element is equipped on two opposite sides with a slot that receives said terminal therein;

said terminals individually have a tube disposed on the upper portion, two bent tabs formed on the middle portion, means on the lower portion embracing the bared end of an electrical wire and a slant tab extending from the lower end;

said tube being configured to have on the upper portion thereof a straight duct portion having an inside diameter slightly larger than the thickness of the leads of the LED light bulb and on the lower portion thereof a reduced duct portion that is defined by a plurality of inwardly inclined elastic fingers and that gradually reduces from the top to the bottom until its inner diameter is slightly smaller than the lead thickness of the LED light bulb,

said bent tabs each extending towards two opposite sides, with the bent portion thereof separated from each other by a distance slightly smaller than the thickness of said insertion element, said terminals each associated with an electrical wire being inserted into the slots on two opposite sides of said insertion element, with two bent tabs holding the body of the insertion element, and then the insertion element being slid into the holder body until it being caught in position by an engagement of the inwardly projecting lower rim of the holder with two latch elements formed on the lower end of the insertion element.

2. The improved LED light bulb holder structure as claimed in claim 1 wherein the engagement means provided on the lower portion of said LED light bulb and the inner wall surface of said holder body can be either an annular recessed groove or raised bump, or two or more annular grooves or bumps as required.

3. The improved LED light bulb holder structure as claimed in claim 1 wherein the engagement means provided on the lower portion of said LED light bulb and the inner wall surface of said holder body can be recessed or raised dots.
