Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a holder for an illuminated bulb constituting a small luminaire for use in electrical decoration such as a showcase or a showroom.

[0002]

[Prior art]

 An electric decoration valve may be used by inserting a lower end portion where two conductive wires extend into an insertion portion of a valve holder and fitting the holder to a connector attached to a main wiring. .

[0003]

[Problems to be solved by the invention]

 If the valve and the holder are not fixed to each other, the valve often comes off from the holder, or the electrical contact between the valve and the holder is cut off, making it impossible to turn on the bulb. To prevent such accidents, the lower end of the valve may be fixed to the holder with adhesive. However, the work of applying the adhesive to the valve and the holder is generally troublesome.

An object of the present invention is to provide a lamp holder for decoration which can easily fix the valve and the holder in order to save such labor.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention is based on the premise that a cylindrical insertion portion capable of inserting and extracting the lower end portion of a valve having two conductive wires extending from the lower end portion, and a bottom portion of the insertion portion. An electric decoration valve holder having a pair of through holes through which the conductive wire can be inserted.

[0006] On this premise, the present invention is characterized in that the holder can abut on the inner surface of the insertion portion and the outer peripheral surface of the lower end portion of the valve, and intermittently extends in the direction around the insertion portion. And a plurality of projections extending inward in the radial direction of the insertion portion.

In one embodiment of the present invention, the protrusion extends in a direction in which the valve is inserted.

[0008] In one embodiment of the present invention, the protrusion extending in the insertion direction of the valve approaches the center axis of the insertion portion as it advances forward from the insertion end of the insertion portion in the insertion direction. It is inclined.

[0009]

[Embodiment of the invention]

 The details of the illuminated bulb holder according to the present invention will be described below with reference to the attached drawings.

FIGS. 1 and 2 are a perspective view of a bulb 2 and a bulb holder 9 constituting the lamp 1, and a perspective view of the lamp 1 with the bulb 2 inserted inside the holder 9. The holder 9 of FIG. 1 is shown in a partially broken state.

The valve 2 has a glass body 3 having a vertically long hollow cylindrical shape, and a mount 4 mounted inside the body 3. The mount 4 has two conductors 5 extending in parallel with each other in the vertical direction of the bulb 2 and a filament 6 connecting the inner ends of the conductors 5, and each of the conductors 5 is a glass flare 7. Supported. Two conducting wires 8 extend downward from the lower end 2 a of the body 3.

The holder 9 is formed of an insulating synthetic resin, and has a vertically long cylindrical valve insertion portion 10 and a base portion 11 located at the lower end of the insertion portion 10. The insertion portion 10 has a flange 13 formed on the outer peripheral surface of the top.

The base 11 has a pair of through holes 12 that are connected to the insertion portion 10 and extend in the up-down direction. When the lower end 2 a of the bulb 2 is inserted into the insertion portion 10, each end 15 of the conductor 8 extends downward from the through hole 12. The extended end 15 of the conductor 8 is folded upwardly of the bulb 2 and overlaps the outer peripheral surface of the base 11 (see FIG. 2) to form a pair of male contacts for the positive and negative electrodes. I have. The base 11 is inserted into a lamp socket (not shown) forming a female contact.

A large number of ridges 14 are formed on the inner peripheral surface of the insertion portion 10 so as to protrude inward in the radial direction and extend by an appropriate length in the insertion direction of the valve 2. As shown in the AA line arrow view of FIG. 1, the protruding ridge 14 extends so as to have a larger radially inwardly protruding dimension from the upper end to the lower end of the holder 9. However, the projecting dimension of the ridge 14 inward in the radial direction may be uniform without being so large.

When the valve 2 is inserted into the holder 10, the outer peripheral surface of the body 3 of the valve 2 comes into pressure contact with the ridge 14, and the valve 2 can be fixed to the holder 9.

The valve 2 and the holder 9 can be fixed to each other via an adhesive applied to the inner peripheral surface of the insertion section 10. When the adhesive is used, when the lower end portion 2a of the valve 2 is inserted, excess adhesive or air trapped in the insertion portion 10 is discharged from between the ridges 14, so that the ridge is formed. As compared with the case where the insertion is not provided, the insertion of the lower end 2a and the bonding work are easier. The holder 9 may be made of an elastic material or an inelastic material, but if it is an elastic material, when the valve 2 is inserted, the ridge 14 is elastically deformed. As a result, the valve 2 is pressed against the outer peripheral surface of the body 3 with a large area, and the valve 2 can be reliably held.

[0017]

[Effect of the invention]

 According to the lamp holder for electric decoration according to the present invention, when the valve is inserted into the holder, the projection formed on the inner peripheral surface of the insertion portion and the outer peripheral surface of the body of the valve are pressed against each other. It can be easily fixed to the holder. When the valve and the base are fixed to each other by using an adhesive, excess adhesive and air can be easily discharged from between the ridges.
