BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent lamp socket.

[0002]

2. Description of the Related Art Conventionally, a fluorescent lamp socket used for lighting equipment which is considered according to a user's order is shown in FIG.
The following are known. This fluorescent light socket is
A terminal pin insertion hole for inserting and holding a terminal pin of the fluorescent lamp is provided on the front surface 102 of the socket case 101, and a lead wire 104 is inserted through a through hole provided on the rear surface 103 of the socket case so as to be substantially parallel to the terminal pin insertion hole. It has been pulled backward. This lead wire 104 is
It is passed through a fitting or a pipe 105. On the other hand, the fluorescent lamp 106 is supported by an appropriate lamp receiver (not shown). However, at the time of construction, there are many cases where the position of the fluorescent lamp 106 supported by the lamp receiver does not exactly match the mounting fixture or the pipe 105. For example, as shown by a two-dot chain line in FIG.
If is located obliquely above the fitting or the pipe 105, the lead wire 104 must be bent to forcefully align the position. In particular, since the illustrated socket case 101 has a large length in the front-rear direction, it cannot be easily accommodated in a narrow place, and the load on the lead wire 104 also increases.

[Problem to be solved by the invention]
The present invention aims to provide a fluorescent lamp socket that can be mounted without bending a lead wire as much as possible even in a narrow place or when the positional relationship between the fluorescent lamp and the mounting fixture or pipe does not exactly match.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1A is a front view of the fluorescent lamp socket 1 of the embodiment, FIG. 1B is a rear view, FIG. 1C is a bottom view, and FIG. 2A and 2B show the fluorescent lamp socket 1 respectively.
3A is a rear view showing the fluorescent lamp socket 1 with the lid removed, and FIG. 3B is a rear view of the lid.

The fluorescent lamp socket 1 comprises a fluorescent lamp 1
A case body 2 having terminal pin insertion holes 21 and 21 on the front surface 22 for inserting and holding the terminal pins 107 of No. 06, and a lid 3 detachably fixed to the back of the case body. A socket case is constituted by 2 and lid 3.

As shown in FIG. 3A, support portions 23 of the socket-side terminals 4 are formed in the case body 2 at positions corresponding to the terminal pin insertion holes.
Each of the socket-side terminals 4 connected to the support portion 23 is mounted on the support portion 23. A female screw part 24 is formed below the pair of support parts 23, 23.

As shown in FIG. 3B, a wall 31 for separating lead wires, retainers 32 and 32 for fixing socket-side terminals, and a screw insertion hole 33 are formed on the back surface of the lid 3. Have been. Then, the lid 3 is fitted to the case body 2,
A screw (not shown) is inserted through the screw insertion hole 33 and fixed by screwing into the female screw portion 24.

A lower surface insertion hole 25 for a parallel lead wire is formed on the lower surface of the case body 2. The lower surface insertion opening 25 is a substantially rectangular opening having a sufficient space through which the two lead wires 51, 51 can be inserted, and one side thereof is open to the rear surface of the case body 2. On the other hand, near the lower end of the lid 3, a rear surface insertion hole 34 for a parallel lead wire is formed. The rear insertion hole 34 has two lead wires 51,
A substantially oval opening having a sufficient space through which the hole 51 can be inserted. Between the rear insertion hole 34 and the lower end of the lid 3,
A communication port 35 is formed. The communication port 35 is formed narrow enough to allow only one lead wire 51 to pass therethrough. Then, as best shown in FIG. 1D, the case body 2 and the lid 3 are assembled so that the lower surface insertion port 25 and the rear surface insertion port 34 are connected via a narrow communication port 35. Can be Note that D in FIG. 1 is drawn upside down from the other figures.

Next, a method of using the fluorescent lamp socket 1 will be described. First, when the fluorescent lamp 106 and the fixture or pipe 105 are in the positional relationship shown in FIG. 2A, the parallel lead wire 5 is pulled out from the rear insertion hole 34 rearward, that is, substantially parallel to the terminal bin insertion hole. Accordingly, wiring can be performed without difficulty even in a narrow space and without burdening the parallel lead wires 5.

On the other hand, as shown in FIG. 2B, when the parallel lead wire 5 is drawn downward from the lower surface insertion opening 25, that is, in a direction intersecting with the terminal pin insertion hole, the parallel lead wire 5 is connected. It is necessary to bend extremely, and a load is imposed on the parallel lead wire 5, which may cause breakage. However, as shown by the two-dot chain line in FIG.
If the parallel lead wire 5 is pulled downward from the above, smooth wiring can be achieved.

As described above, in the fluorescent lamp socket 1 of the present invention, the position where the parallel lead wire 5 is drawn can be changed according to the positional relationship between the fluorescent lamp 106 and the fixture or the pipe 105. Even in a narrow place, smooth wiring can be performed without imposing a burden on the parallel lead wires. Furthermore, the fluorescent lamp socket 1 of this embodiment
Then, a portion 1a having a terminal pin insertion hole is provided at an upper portion,
Since the portion 1b having the lower surface insertion port 25 and the rear surface insertion port 34 is extended below, the entire length a in the front-rear direction is shortened, and the front and rear space can be used without difficulty even in a narrow space. Further, in this embodiment, the communication port 35
Since the two insertion ports 25 and 34 are connected, it is possible to easily change the position where the parallel lead wire 5 is pulled out through the communication day 35. Moreover, this communication port 35 is
Since the lead wire 51 is formed narrow enough to allow the lead wire 51 to pass through, even if the worker can move the lead wire 51 one by one by hand, the operator can move between the two insertion openings 25 and 34, but without permission. There is no danger that the parallel lead wire 5 will move.

The present invention is not limited to the above embodiment. For example, the positions and shapes of the two insertion ports 25 and 34 can be appropriately changed and provided. The size, interval, shape, and the like of the terminal pin insertion holes 21 can be variously changed according to the fluorescent lamp to be used.

[0015]

As described above, the present invention is applicable to a fluorescent lamp which can be mounted without bending the parallel lead wires as much as possible even in a narrow place or when the positional relationship between the fluorescent lamp and the mounting fixture or pipe does not exactly match. A socket could be provided. In particular, it is possible to easily and easily change the lead-out position of the parallel lead wire, and to prevent the parallel lead wire from being arbitrarily pulled out and moved to another insertion port after the change. . According to the second invention of the present application, in addition to the above-described effects, it is possible to provide a fluorescent lamp socket that can easily perform lead wire connection work and socket assembly work.
