Abstract

A light bulb holder structure in which there is no need for connection terminals. The holder is especially suitable for LED type light bulbs. It primarily comprises a coupling element seated therein. Electrical wire'"'"'s bare conductive ends are disposed on two sides of the coupling element to get in touch with the leads of a light emitted diode that is seated on the top of the holder with leads extending into two vertical openings of the coupling element. The holder according to the invention can provide excellent electrical contacts and sturdy combination between light emitted diodes and electrical wires.

Claims

1. A holder structure without connection terminals used for Christmas decorative light bulbs comprising:

a holder body adapted for receiving a light bulb or a light emitting diode in a first end thereof;

a coupling element inserted into a second end of said holder body, said coupling element having a pair of longitudinally directed openings formed in one end thereof for respectively receiving a pair of leads of a light bulb or light emitting diode therein; and

two electrical wires disposed on two opposite sides of the coupling element, each of said electrical wires having an extended bared conductive end extending through a respective one of said longitudinally directed openings and being bent over said one end of said coupling element, each said bared conductive end being in contiguous contact with a corresponding lead of a light bulb or a light emitting diode within a respective one of said longitudinally directed openings to form an electrical connection therewith, said coupling element including a pair of projecting pins respectively extending from opposing sides of said coupling element, each said bared conductive end of said electrical wires having an intermediate portion wrapped around a respective one of said projecting pins.
