Abstract

PURPOSE:To reduce the number of parts and simplify the mounting process by constituting one shoulder part of a socket main body out of a mounting spring to press down elastically from above. CONSTITUTION:When a fluorescent lamp 2 is inserted in the plug 5 for fluorescent lamp resisting the elasticity of a socket main body, a base pin 6 comes to naturally contact with a contacting part 7. Also, since the fluorescent lamp 2 end the plug 5 for the fluorescent lamp contact each other closely, the gap between both comes to bear air-tightness, so the moisture never enter from here and similarly the moisture never enter from between a lead hole 9 and a lead wire 8 inserted into here, either. As a result, by inserting the fluorescent lamp 2 into the plug 5 for fluorescent lamp of the socket main body, the inside of the socket main body comes to be provided with a water preventive function. Hereby, the number of used parts required for installing an apparatus rain body can be reduced and further, the mounting process to the apparatus main body can be simplified.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a socket device for a fluorescent lamp.

(Prior Art) A conventional socket device used for fluorescent lamps consists of a box-shaped socket body with a contact piece inside which the tip of the fluorescent lamp bottle comes into contact with, a socket base that supports this body, and a socket base that supports the socket base. A fixture and a lock that are attached to the fixture body for installation in a lighting fixture.

Also, when it is necessary to make the socket waterproof, it is usually made up of the surface of the socket body and a gasket that is tightened by the cap of the fluorescent lamp.

However, according to this configuration, in addition to the socket body,
This method requires a socket stand, a mounting tool, a gasket, etc., which increases the number of parts used, and has drawbacks such as the process of installing these parts together becomes complicated.

(Problems to be solved by R-ming) This invention minimizes the number of parts required to install the waterproof function in the device body, and also reduces the installation process to the device body. The purpose is to simplify.

(Means for Solving the Problems) The present invention consists of a molded body made of a waterproof and elastic rubber material, and one end surface of the fluorescent lamp has a diameter such that the end of the fluorescent lamp can be press-fitted therein. It has an insertion hole, and has a contact part inside thereof that comes into contact with a cap pin of a fluorescent lamp press-fitted into the fluorescent lamp insertion hole, and a lead wire connected to the contact part is pressure-welded to the other end surface. a socket body having a lead hole through which the socket is inserted in the state, and further having shoulders on both sides of the exterior;
a fixture body of a lighting fixture that accommodates the socket body; a bent portion at a tip of a side wall of the fixture body that presses down from above one shoulder of the socket body housed in the fixture body;
The present invention is characterized by comprising an attachment spring that is attached to the instrument body and elastically presses down the other shoulder of the socket body from above.

(Example) An example of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a socket body made of a molded body of a waterproof and elastic rubber material. This is on one end of it.

A fluorescent lamp insertion hole 5 is formed with a diameter such that the end portion of the fluorescent lamp 2, including the base 3 and the end portion 4 of the glass tube, is press-fitted therein.

Further, the inside thereof is provided with a contact portion 7 that comes into contact with the base pin 6 of the fluorescent lamp 2 press-fitted into the fluorescent lamp insertion hole 5. This contact portion 7 is preferably a tulip contact, for example, and has a single cap pin 6.
They come into contact with each other by hugging them.

The other end surface of the socket body 1 has a lead hole 9 into which a lead wire 8 connected to the contact portion 7 is inserted in a pressed state.

Shoulders 10 are provided on both sides of the exterior of the socket body 1. Also, the fixture body 1 of the lighting fixture that stores the socket body 1
1, which includes one shoulder 10 of the socket body 1.
A bent portion 12 for pressing down from above is formed at the tip of side g&13.

14 is an attachment spring whose base end is attached to the instrument body 11. This is used to elastically press down the other shoulder portion 10 of the socket body 1 from above. 15 is a box that stores ballasts and other equipment necessary for lighting fluorescent lights.
It is attached to the instrument body 11.

In the above configuration, when the fluorescent lamp 2 is inserted into the metal lamp insertion hole 5 against the elasticity of the socket body 1, the first cap pin 6 comes into natural contact with the contact portion 7. In addition, since the fluorescent lamp 2 and the fluorescent lamp insertion hole 5 are in close contact with each other, the gap between the two surfaces becomes airtight, and no moisture can enter from there. There is no possibility that moisture will infiltrate between the lead wire 8 and the lead wire 8 that is inserted into the lead wire 8.

As a result of the above, by inserting the fluorescent lamp 2 into the fluorescent lamp insertion hole 5 of the socket main body 1, the interior of the socket main body 1 is provided with a waterproof function.

Prior to insertion of the fluorescent lamp 2 described above, the socket main body 1 is housed inside the appliance main body 11 as shown in FIG. 6. At that time, one shoulder portion 10 of the socket body 1 is placed on the side lJ
! , 13 are engaged with the bent portions 12 of them.

It begins to be pressed down from above. Also, the other shoulder portion 10
is similarly pressed down from above by the tip of the attachment spring 14.

Through the above steps, the socket main body 1 is fixed to the instrument main body 11. For this installation, there is no need for a conventional socket stand. Further, since only the engagement with the side wall 13 and the mounting spring 14 is required, the work is easy.

(Effects of the Invention) As detailed above, according to the present invention, even if this socket is equipped with a waterproof function as a socket for a fluorescent lamp, the number of parts required to be installed in the main body of the device can be minimized as much as possible. Moreover, it is possible to simplify the installation process to the instrument body.
