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.
Description
TITLE: IMPROVED LIGHT EMITTED DIODE LIGHT BULB
HOLDER USED IN LED TYPE CHRISTMAS LIGHT BULB STRING
BACKGROUND OF THE INVENTION
Incandescent bulbs used in a conventional Christmas light bulb string produce heat and result in high temperature, which provides inconvenience in, use. Thus light emitted diodes are used in place of conventional light bulbs in Christmas light bulb strings. However, light emitted diodes currently used in Christmas decorative light bulb strings are simply substitutes for conventional incandescent bulbs. They used a holder structure that was designed for conventional light bulbs. Due to the limitation of LED structures, those conventional holders brought much inconvenience in use and assemblage to users and manufacturers when they were used for LED light bulbs. The conventional structure often leads to~ a poor electrical connection between the leads of a light bulb diode light bulb and electrical wires. This is primarily because that the leads of a light emitted diode is made of a different material that is often thicker and harder than the leads of a conventional light bulb. Further, the leads of a light emitted diode is often coated with a layer of electroplated material. This makes the leads of a light emitted diode unable to be bent like an incandescent light bulb. If the leads were bent by forces, the electroplated layer will break and the metal underneath the coated layer will be exposed to the outside. Finally metal oxidization occurs. Besides, conventional light bulb holder structures also bring trouble to assembling work and provide a poor electrical connection between LED light bulbs and electrical wires.
i Accordingly, it is the primary object of the invention to provide an improved holder structure for LED light bulbs used in Christmas light bulb strings, in which the drawbacks of a conventional structure have been eliminated by using specially designed insertion elements and terminals of electrical wires. Now the structural features and advantages of the invention will be detailed with reference to the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIIVVIENTS
2 As shown in figures 1 through 4, the light bulb holder according to the invention comprises a holder body (4) accommodating a light bulb (3) on the top thereof, and an insertion element (2) housed in the holder body (4). The insertion element (2) is equipped on each of two opposite sides with a slot (21 ). Each slot (21 ) receives a terminal ( 1 ). The light bulb (3 ) is furnished on the cylindrical surface of the lower portion with an annular groove (31 ) (or an annular bump). The light emitted diode (LED) inside the light bulb (3) has two straight leads extending vertically downwards. The holder body (4) comprises an annular flange (41 ) on the internal wall surface near the upper opening corresponding to the annular groove (31) of the light bulb (3), or an annular groove if the corresponding portion on the light bulb (3) is provided with an annular bump. The annular flange (41 ) (or the annular bump) of the holder body (4) is designed as coupling and locating means to engage with the annular groove (31 ) (or the annular bump) of the light bulb (3) when the LED
light bulb (3) is mounted on the holder body (4). Thus the light bulb (3) and the holder body (4) can be joined in an easy way. Furthermore, the holder body (4) is provided on the lower end rim with inward protrusions (42).
The present invention is featured by the design of terminals ( 1 ).
Referring to figures 5 and 6, the upper portion of the terminal ( 1 ) is a tube ( 11 ). The tube ( 11 ) is configured to have a straight duct portion on the upper portion. The cylindrical wall of the straight duct portion extends downwards and splits on the lower portion into several spaced elastic fingers ( 111 ), which inwardly obliquely extend to define a reduced duct
light bulb (3) is mounted on the holder body (4). Thus the light bulb (3) and the holder body (4) can be joined in an easy way. Furthermore, the holder body (4) is provided on the lower end rim with inward protrusions (42).
The present invention is featured by the design of terminals ( 1 ).
Referring to figures 5 and 6, the upper portion of the terminal ( 1 ) is a tube ( 11 ). The tube ( 11 ) is configured to have a straight duct portion on the upper portion. The cylindrical wall of the straight duct portion extends downwards and splits on the lower portion into several spaced elastic fingers ( 111 ), which inwardly obliquely extend to define a reduced duct
3 portion. The inside diameter of the straight duct portion of the tube (11) is slightly larger than the thickness of the leads (32) of the LED light bulb (3). However, the inside diameter of the reduced duct portion gradually reduces from the top to the bottom until a diameter slightly smaller than the lead thickness of a light emitted diode. Provided on the middle segment of the terminal (1) are two bent tabs (13) respectively extending towards opposite sides of the terminal (1). Distance between the bent portions of two tabs (~3) is dimensioned to be slightly smaller than the thickness of the insertion element (2). The lower portion of the terminal (1) can firmly embrace the bared end (51) of an electrical wire (5) to form a dependable electrical connection. The lower end of the terminal (1) is further provided with a slant tab (12). Two terminals (1) each associated with an electrical wire (S) are individually inserted into two slots (21 ) of the insertion element (2), with the bent tabs ( 13) holding the body of the insertion element (2). Then the insertion element (2) is placed into the holder body (4), with an extension of the protrusions (42) into two latch elements (22) formed on the lower end of the insertion element (2). In this way, the holder of the invention can achieve a sturdy structure.
The leads (32) of the LED (3) are inserted into terminals (1) through the tubular portion ( 11 ) until the lower end of the leads gets in touch of the slant tab (12) while the elastic fingers (111) are biased outwardly as shown in figure 6 so that the terminal can provide an excellent electrical connection and stable support.
Accordingly, with the above arrangement, the invention indeed has the essence of a patent. Although the present invention has been described in
The leads (32) of the LED (3) are inserted into terminals (1) through the tubular portion ( 11 ) until the lower end of the leads gets in touch of the slant tab (12) while the elastic fingers (111) are biased outwardly as shown in figure 6 so that the terminal can provide an excellent electrical connection and stable support.
Accordingly, with the above arrangement, the invention indeed has the essence of a patent. Although the present invention has been described in
4 relation to particular embodiments, it is not limited in any way thereby but is capable of modifications and variants without deviation from the scope of the invention defined by the claims below. As an illustrative example, figure 7 shows another form of the terminal ( 1 ) in which the orientations and positions of the tubular portion ( 11 ) and the slant tab ( 12) have been changed. Figure 8 indicates another embodiment, in which the outer shell (33) of the LED light bulb (3) is provided on the lower rim with such annular grooves that it can be mounted over the top of the holder (4) instead of being seated in the holder. Besides, the structure of the invention can be further simplified by using slots (43) formed on the interior of the holder body as a substitute for the insertion element to accommodate terminals ( 1 ) as shown in figure 9.
