【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1A is a front view of the fluorescent lamp socket 1 of the embodiment, B is a rear view thereof, C is a bottom view thereof, and D is a perspective view of its main part. 2A and 2B are side views showing the usage state of the fluorescent lamp socket 1, respectively, and FIG. 3A is a rear view showing the fluorescent lamp socket 1 with its lid removed, and FIG. [Fig. 4] is a back view of the lid.

This fluorescent lamp socket 1 has a case main body 2 having terminal pin insertion holes 21 and 21 in a front surface 22 for inserting and retaining a terminal pin 107 of a fluorescent lamp 106, and a case main body 2 which is detached from a rear surface of the case main body. The lid body 3 is fixed as much as possible, and the case body 2 and the lid body 3 constitute a socket case.

Inside the case body 2, as shown in FIG. 3A, supporting portions 23, 23 of the socket side terminals 4, 4 are formed at positions corresponding to the terminal pin insertion holes, and are connected to the lead wire 5. Each of the socket side terminals 4 thus formed is mounted on the support portion 23. A female screw portion 24 is formed below the pair of support portions 23, 23.

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

On the lower side surface of the case body 2, a side insertion hole 25 for a lead wire is formed. The side insertion port 25 is a substantially rectangular opening having a sufficient space for inserting the two lead wires 5 and 5, and one side thereof is open to the rear surface of the case body 2. .. On the other hand, a rear insertion hole 34 of the lead wire is formed near the lower end of the lid 3. The rear insertion opening 34 is a substantially oval opening having a sufficient space for inserting the two lead wires 5 and 5. A communication port 35 is formed between the rear insertion port 34 and the lower end of the lid 3. The communication port 35 is formed so narrow that only one lead wire 5 can pass through. Then, as best shown in D of FIG. 1, the case body 2 and the lid body 3 are assembled so that the side insertion opening 25 and the rear insertion opening 34 are connected through a narrow communication opening 35. Attached. It should be noted 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 the pipe 105 are in the positional relationship shown in FIG. 2A, the lead wire 5 is moved backward from the rear insertion port 34, that is, substantially parallel to the terminal pin insertion hole, By pulling it out, it is possible to perform wiring in a narrow space without any difficulty and without imposing a burden on the lead wire 5.

On the other hand, as shown in FIG. 2B, when the lead wire 5 is pulled out downward from the side insertion port 25, that is, in the direction intersecting with the terminal pin insertion hole, the lead wire 5 is pulled out. It becomes necessary to bend it extremely, which puts a burden on the lead wire 5 and may lead to damage. However, as shown by the chain double-dashed line in FIG. 2B, when the mounting fixture or the pipe 105 is located below, pulling the lower lead wire 5 out of the side insertion opening 25 allows smoother wiring. Becomes

As described above, in the fluorescent lamp socket 1 of the present invention, the lead-out position of the lead wire 5 can be changed according to the positional relationship between the fluorescent lamp 106 and the fixture or the pipe 105. Smooth wiring is possible even in places without burdening the lead wires. Further, in the fluorescent lamp socket 1 of this embodiment, the portion 1a having the terminal pin insertion hole is provided in the upper portion, and the portion 1b having the side insertion opening 25 and the rear insertion opening 34 is provided below the extension portion 1a. Since the length a in the front-rear direction is shortened, it can be used comfortably even in a narrow space in the front and rear. Furthermore, in this embodiment, since the above-mentioned both insertion ports 25 and 34 are connected by the communication port 35, the lead-out position of the lead wire 5 can be easily changed through the communication port 35. Moreover, since the communication port 35 is formed so narrow as to allow one lead wire 5 to pass therethrough, the operator manually moves the lead wire 5 one by one so that the two insertion ports 25, Even if it is possible to move between 34, there is no risk that the lead wire 5 will move without permission.

The invention of the present application is not limited to the above-mentioned embodiment, and, for example, the positions and shapes of the both insertion ports 25 and 34 can be appropriately changed and provided. Further, in the first consideration of the present application, it is not always necessary to provide the communication port 35, and both the above-mentioned insertion ports 25 and 34 can be implemented as independent openings. Further, the side portion insertion port may be a lateral side portion insertion port 34a that opens laterally, as indicated by a two-dot chain line in D of FIG. 1, for example. In this example, the lateral side insertion port 34a is formed vertically long so that two lead wires can be inserted vertically, but it may be formed horizontally long. Further, although the lateral side insertion opening 34a and the side insertion opening 25 are connected by the communication opening 35a, the lateral side insertion opening 34a and the rear insertion opening 34 may be directly communicated with each other. Further, the lateral side insertion holes 34a can be formed in left-right symmetry. Further, the size, interval, shape, etc. of the terminal pin insertion holes 21 can be variously changed according to the fluorescent lamp used.
