Abstract

PURPOSE:To use two kinds of fluorescent lamp, a general type fluorescent lamp and a fluorescent lamp having pins more than four, without wasteful demand by forming a plunger with pin insertion holes more than four. CONSTITUTION:A plunger has four insertion holes 18, 18', 19, 19' in square and a recessed channel 21 on the periphery thereof. A general type fluorescent lamp can be used by inserting two pins of one end of a tube into the pin insertion holes 18, 18' corresponding to a first and a second wiring means 23, 24. About a fluorescent lamp having four pins in one end of a tube, two pins corresponding to one filament are inserted into the pin insertion holes 18, 18' corresponding to the first and the second wiring means 23, 24, and one of other two pins is inserted into the pin insertion hole 19 corresponding to the first wiring means 23, and the other one is inserted into the pin insertion hole 18, not corresponding to the wiring means. In this way, electrical feeding is performed against one filament, but electrical feeding is not performed against the residual filament. Two kinds of fluorescent lamp, a fluorescent lamp having pins more than four in one end of a tube and a general type fluorescent lamp, can be used commonly at low cost.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] <Industrial Application Field> The present invention relates to a socket device for mounting a discharge lamp such as a fluorescent lamp.

(Conventional technology) Traditionally, fluorescent lamps had two pins at one end of the tube.

It is normal to have two on the other end. however,
As shown in Figure 2 of Utility Model Publication No. 30-4572 @ Publication,
It has been proposed to have four pins at the end of the tube.

In order to extend the life of the fluorescent lamp, two filaments were installed at one end of the tube, and even if one filament broke, the other filament could be used, allowing the same lamp to be used. It is something to do. Also,
The above-mentioned publication describes: - A lamp having two filaments provided at one end of the tube (four pins protruding from one end of the tube) can be attached to a fluorescent lamp socket device without a membrane; A separate adapter is used.

(Problem to be Solved by the Invention) However, although this product can extend the life of the lamp, it has the disadvantage of being expensive because it requires a separate adapter, and this point is difficult to put into practical use. It was a challenge.

The present invention was made in view of these problems, and provides a socket device that can be used in common at low cost for two types of lamps: a lamp having four or more pins at one end of the tube, and a generally used fluorescent lamp. It's about doing.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a method for pressing a plunger having four or more lamp pin insertion holes, and for two of the pin insertion holes to be connected to two ends of a power source. The invention is characterized in that it has a first wiring means so as to be connected thereto, and a second wiring means for one of the remaining pin insertion holes so as to be connected to the other end of the power supply. It is a socket device.

(Function) According to the configuration of the present invention, - the intra-membrane fluorescent lamp is configured such that the two pins at one end of the tube are connected to the first and second pins, respectively. It can be used by inserting it into the pin insertion hole corresponding to the second wiring means.For fluorescent lamps that have four pins at one end of the tube, two pins for one filament can be inserted into the first. Insert one of the other two pins into the pin insertion hole corresponding to the second wiring means.
A book is inserted into a pin insertion hole corresponding to the first wiring means, and the other book is inserted into a pin insertion hole not corresponding to the wiring means.

In this case, power is supplied to one filament, but power is not supplied to the remaining filaments. Note that the same socket device as the socket device at one end of the tube is used for the pin at the other end of the tube.

(Example) An example of the present invention will be described using FIGS. 1 to 4.

Fig. 4 shows a straight tube type fluorescent lamp having two filaments at one end of the tube, 3.4 is the filament, 1 is pulp, 2 is the stem, 5 is the lead wire of filament 3, and 6 is the filament 4. The lead wire 8°8- is the pin of the filament 3, and the lead wire 9.9'' is the pin of the filament 4.

Note that the pin spacing of the film-type fluorescent lamp, the 8° 8-pin spacing, and the 9.9'' pin spacing are the same.

Further, 8, 9.8", and 9" are arranged so as to be located in the squares.

11 is a socket main body, and a front part 13. Back part 12
Consisting of The front part 13 has screw holes 14°1 on both sides.
4 and an opening 15 at the center of the top, exposing a plunger to be described later. Also, at the bottom is the first. Second power supply hole 1
5.16 has been established. Front part 13. The back part 14 is secured by screwing screws into the screw holes 14.14.

20 is a franchisor with a square pin insertion hole 18°18-
, 19.19=, and has a groove 21 on the circumference.

23 and 24 are the first two-shaped plunger pressing springs, respectively. This is the second conduction means. That is, the lower part in FIG. 3 can be pressed against the power supply hole and connected to the power supply line, and the upper part of the first conduction means 23 is connected to the pin insertion hole 19.1.
8, and the upper part of the second conductive means 24 is inserted into the pin insertion hole 1.
8- is suppressed.

According to this embodiment, the membrane-type fluorescent lamp lights up when the pin is inserted into the pin insertion holes ia and ia'.

No matter what method you use, the light lamp shown in Figure 4
There are only two ways to insert the pin, and in each case, only one filament is powered and the other filaments are not powered, so it is easy to handle. In the case of this embodiment, power is similarly supplied to only one filament in the lamp shown in FIG. 2 of the above-mentioned publication, and no power is supplied to the other filaments. However, the distance between the pins corresponding to each filament is 18
．． 19” spacing, must be the same as 19.18” spacing.

In this embodiment, the first conduction means 23 and the second conduction means 2
Although the shape of the first conduction means 23 is different from that of the second conduction means 24, the first conduction means 23 may have the same shape as the second conduction means 24. However, in this case, the lamp shown in Figure 2 of the publication cannot be used.

[Effects of the Invention] Since the socket device of the present invention has four or more pin insertion holes formed in the plunger, it can be used at low cost without requiring an adapter or the like as in the conventional case. Two types of fluorescent lamps having the above pins can be used without wasting power consumption.
