Abstract

PROBLEM TO BE SOLVED: To completely prevent the release of a bulb, a bulb socket, and a terminal socket by shrinking a heat-shrinkable synthetic resin cover tube, and integrally pressing and covering the upper half of the spherical bulb, the bulb socket, and the upper section of the terminal socket. SOLUTION: Lead wires 6, 11 of a bulb 4 led out of the tail section of a bulb socket 5 inserted with the bulb 4 are folded to the side section of the bulb socket 5, and the bulb socket 5 is inserted into a terminal socket 3. A terminal 2 hooked and fixed to the terminal socket 3 is kept in contact with the lead wires 6, 11. A soft heat-shrinkable synthetic resin cover tube 8 is coupled with a part of the terminal socket 3 inserted with the bulb socket 5 so that the upper end section is located at the portion smaller in diameter than the equator portion of the spherical bulb 4 as shown by a chained line, then the tube 8 is heated and shrink. The bulb 4, bulb socket 5, and terminal socket 3 can be integrally pressed and covered.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light bulb holding cover for a Christmas light for holding a decorative light bulb and a socket.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional decoration light for Christmas has a terminal 2 fixed to the end portions of a pair of conductors 1 fixed to a not-shown groove in a terminal socket 3. I do. On the other hand, when the lead wire 6 of the bulb 4 coming out of the tail of the bulb socket 5 into which the bulb 4 is inserted is bent to the side of the bulb socket 5 and the bulb socket 5 is inserted into the terminal socket 3, the groove in the terminal socket 3 becomes The terminal 2 and the lead wire 6 that are locked and fixed are in contact with each other.

[0003]

As shown in FIG. 2, when the bulb 4 is spherical or large, the bulb 4 is prevented from falling off from the bulb socket 5.
An adhesive is applied to the light bulb receiving portion 7 to bond the light bulb 4. However, the adhesive is evenly applied to the inner surface of the bosh-shaped light bulb receiving portion 7, and furthermore, the adhesive is not protruded from between the light bulb 4 and the light bulb receiving portion 7 when the light bulb 4 is inserted. It is extremely difficult to apply an appropriate amount. Furthermore, since the terminal socket 3 and the bulb socket 5 fitted to the terminal socket 3 are made of a hard synthetic resin, there is a problem that the terminal socket 3 comes off due to vibration or shock. It was hoped to eliminate it.

[0004]

According to the present invention, a part of a decorative bulb 4, a bulb socket 5 for inserting and supporting the bulb 4, and a terminal socket 3 for inserting the bulb socket 5 are provided.
A cover tube 8 made of a heat-shrinkable synthetic resin is fitted into a part of the tube, and the tube 4 made of a heat-shrinkable resin is heated and shrunk, so that the light bulb 4, the light bulb socket 5, and the terminal socket 3 are heated.
The cover is configured to be pressed down and integrated.

BEST MODE FOR CARRYING OUT THE INVENTION

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A Christmas light bulb holder cover according to the present invention will be described with reference to FIG. Components having the same structure as that described in FIG. 2 are denoted by the same reference numerals, and description thereof is omitted.

In the spherical bulb 4, a bimetal 10 or the like that is deformed by a change in temperature is provided on a lead wire supporting portion 9, and the tip of the lead wire 6 is brought into contact with this bimetal 10, and the tip of another lead wire 11 is contacted. Between filament 1
2 is provided. Now, when the lead wires 6 and 11 are energized to cause the filament 12 to emit heat and emit light, the bimetal 10 is heated and deformed, separates from the lead wire 6 and cuts off the current to the filament 12 and turns off. When the temperature of the bimetal 10 decreases, the bimetal 10 deforms and contacts the lead wire 6 again to energize the filament 12, thereby lighting the electric bulb 4. In this way, the light bulb 4 can be turned on and off.

[0008] The bulbs 6 and 11 of the bulb 4 protruding from the tail of the bulb socket 5 into which the bulb 4 is inserted are bent to the side of the bulb socket 5 and the bulb socket 5 is connected to the terminal socket 3.
, The terminal 2 fixed to the terminal socket 3 and fixed and the lead wires 6 and 11 come into contact with each other.

A bulb tube 5 for supporting the bulb 4 and a cover tube 8 made of a soft heat-shrinkable synthetic resin in a part of the terminal socket 3 into which the bulb socket 5 is inserted as shown by a dashed line. After fitting the upper half, that is, a portion smaller in diameter than the equator portion of the bulb 4 so that the upper end is located, the synthetic resin tube 8 is heated and shrunk so that the bulb 4, the bulb socket 5 and the terminal socket 3 are heated.
Can be covered by pressing them integrally as shown in FIG.

[0010]

According to the present invention, by shrinking the cover tube 8 made of a heat-shrinkable synthetic resin, the upper half of the bulb 4, that is, a portion smaller in diameter than the equator portion of the bulb 4, and the bulb socket 5. And the upper part of the terminal socket 3 are integrally pressed to cover, thereby completely preventing each of them from falling off.

Conventionally, the adhesive is evenly applied to the inner surface of the bosh-shaped light-bulb receiving portion 7 of the light-bulb socket 5, and when the light bulb 4 is inserted, the adhesive is stuck between the light bulb 4 and the light-bulb receiving portion 7. It is easy to manufacture and assemble, and mass production is possible, since the extremely difficult work of applying an appropriate amount so as not to be disturbed is omitted, and the cover tube 8 made of a heat-shrinkable synthetic resin is simply fitted and heated. Moreover, the cost could be reduced.

Light bulb 4, light bulb socket 5, and terminal socket 3
Is covered with the cover tube 8, so that it is possible to prevent rainwater or the like from entering from the respective joints of the bulb 4, the bulb socket 5, and the terminal socket 3.

Light bulb 4, light bulb socket 5, and terminal socket 3
Thus, the tube 8 is completely covered with the joint portion between the bulb 4 and the bulb 4, so that the bulb socket 5 and the terminal socket 3 other than the bulb 4 can be prevented from being damaged.

Since the easily breakable light bulb 4 is covered with the elastic synthetic resin tube 8, the light bulb 4 does not come into contact with each other and is damaged, so that it is easy to handle.

By making the cover tube 8 colorful or irregular, a variety of decorative Christmas lights could be made using the simple light 4.
