Description

[Detailed description of the invention] (1) Purpose of the invention The present invention relates to a socket for a fluorescent lamp.

Conventionally, elongated fluorescent tubes that have been widely used in offices, workshops, stores, etc. have a cap B attached to both ends of a fluorescent tube A and a pin C at the tip, as shown in FIG. 13, for example.
The pin C at the tip is inserted and connected to the socket D. In this way, the fluorescent tube A is held by the socket D, and this socket D is attached.
In addition, it becomes necessary to provide a separate socket mounting part E.
Furthermore, the socket mounting part E had to be reattached and fixed to the ceiling F, which required a lot of work and required careful work to ensure that the fluorescent tube A was held safely and securely. Furthermore, the pin C inserted into the socket D remains exposed along with the base B, which not only poses a safety problem, but also causes pin C to connect to the socket D due to vibration or contact. There is also a danger that the cap may come off, and since the cap B and pin C are exposed, there are many problems other than safety, such as rust corrosion and damage, in addition to complicating the work. However, the present invention was devised in view of the fatal problems of conventional fluorescent lamp fixtures, and provides safety by completely covering the conventional caps and pins. This coating protects the base and pins,
By fitting the cap parts completely without any gaps, the fluorescent tube can be held safely and securely, and due to this strong fitting, no undue force is applied to the inserted pin itself. In addition to being practical and safe, preventing the exposure of the pins and caps from being exposed is aesthetically pleasing, and also eliminates the need for a socket mounting part, unlike conventional fluorescent lamps. When installing equipment, there are fewer parts, so it is not only economical, but also fast and efficient. This invention was devised for the purpose of providing a socket for a fluorescent lamp that has both functionality and functionality.

(2) Structure of the invention Hereinafter, embodiments of the invention will be described in detail based on the drawings.

FIG. 11 shows an embodiment of the entire fluorescent lamp fixture when using the fluorescent lamp socket of the present invention, and FIG. 1 is a front view of the socket according to the present invention, and FIG. 2 is the same. Although the plan view is shown, the socket of the present invention is shown in Figures 3 to 8.
As shown in the figure, it is composed of both an outer cover 1 and an inner body 2, and FIG. 3 is a longitudinal sectional view of the outer cover 1, and FIG. 4 is a plan view of the same. As shown in FIGS. 3 and 4, its shape is a cylindrical shape with an open top and a bottom, and as shown in FIGS. It is integrally formed and stands upright, and an insertion hole 1b for the cord 3 is provided at the lower end opposite the vertical piece 1a.

The inner body 2 is fitted into the outer cover 1 having such a shape, and the shape of the inner body 2 is shown from below in order to clearly show the shape. As shown in this figure, it has a bottomed top opening and is integrally formed with terminal insertion holes 2a for fitting and inserting the terminals 4 symmetrically at both ends thereof, and at the front and rear sides.
Each has a cord insertion hole 2b and an elongated notch 2c for inserting the cord 3, and FIG. 7 shows only the front side of FIG. 6, and FIG. 8 shows only the rear side. and
The lower part of the cord insertion hole 2b at the center of the front surface of the inner main body 2 in FIG.
A small protrusion 2e is provided at the upper end to cover the entire width.

In order to fit and hold the inner body 2 having such a structure on the outer cover 1, first, the terminal 4 attached to the tip of the cord 3 is inserted and fitted into the terminal insertion hole 2a of the inner body. Cord clamping part 2d
Contact the upper end of the inner cover 1 as shown in FIG.
In other words, in order to clearly show the overall shape of the inner body 2, FIGS. 6 to 8 are shown in the upside down direction compared to when it is used and should be fitted to the outer cover 1. is as described above.

The order of fitting the inner body 2 to the outer cover 1 is to first insert the cord 3 into the cord insertion hole 1b of the outer cover 1, and then insert the terminal 4 into the terminal insertion hole 2a of the inner body 2.
At the same time, the notches 2c of the inner body 2 are fitted into the vertical pieces 1a of the outer cover 1, so that the terminals 4 in FIG. 9 are separated by the vertical pieces 1a and inserted into the terminal insertion holes. The inner body 2 is held and fitted into the outer cover 1. When the middle main body 2 is fitted to the outer cover 1 in this way, since the diameter of the middle main body 2 is approximately equal to the inner diameter of the outer cover 1, the two are strongly retained and fitted. The protrusion 2e in the inner body 2 is positioned so as to abut the upper end of the cord insertion hole 1b in the outer cover 1, that is, to contact the upper end surface of the vertical part of the cord insertion hole 1b having a right angle shape in FIG. As a result, the cord 3 inserted into the cord insertion opening 2b of the inner main body 2 is pressed and clamped and fixed by the protrusion 2e at the upper end of the cord clamping part.

When the inner body 2 is fitted to the outer cover 1 in this way, that is, when the embodiment of FIG. 10 is fitted as shown in FIGS. 1 and 2, the inner body 2
Since the height of the outer cover 1 is lower than that of the outer cover 1, a space 5 is inevitably formed above the inner peripheral surface of the inner peripheral surface of the outer cover 1 as shown in FIG. Then, as shown in FIG. 11, in this space 5,
The cap of the fluorescent lamp is inserted and fitted, and at the same time the pin at the tip of the cap is inserted into the terminal insertion hole 2a formed integrally with the inner body 2, whereby the pin is inserted into the terminal insertion hole 2a. It is connected to the terminal 4, and at this time, since the depth and diameter of the space 5 are equal to those of the cap that is inserted and fitted into the space, the cap portion can be connected to the outer cover without any gap in the space. 1, it is strongly fitted and held.

(3) Effects of the invention The present invention, which has the above-mentioned structure, is designed to hold long and narrow fluorescent lamps that are commonly used in offices, workshops, stores, etc., by replacing the conventional pins at the tips of the caps at both ends of the fluorescent lamp. Instead of using a conventional socket that was inserted into a socket as it is, the present invention uses an outer cover, which eliminates the need for a socket and allows the outer cover to cover the caps at both ends. By completely covering the cap and making the depth and diameter of the space in the outer cover the same as those of the cap, the fit is strong. The pins are simultaneously connected to the terminals that are inserted and fitted into the inner body, which is fitted to the inner body. This not only puts stress on the terminals and pins and reduces the chance of failure, but also allows the terminals inserted and fitted into the inner body to be inserted into the outer cover when the inner body is fitted into the outer cover. In this case, the vertical piece of the outer cover safely isolates each terminal without contact, and this vertical piece further fixes it to the inner body, which inevitably also fixes the terminal in the terminal insertion hole and connects it to the pin. In addition to this safety and the practicality of a strong holding fit between the inner body and outer cover, there is no need for a socket as in the past, and a conventional fluorescent lamp can be used as it is in the inner body of the present invention. It only needs to be inserted into the fitted outer cover, and as there is no exposure of the base or pins, it is safe and has a beautiful appearance even when in use, and has a lot of versatility. This is a unique idea. In addition, as an embodiment of the present invention, if it is used on a ceiling etc., for example, a hanging fitting as shown in Fig. 12 is used to clamp the tube part of the fluorescent lamp and its The upper part may be screwed to the ceiling or the like from below, and the method of use is of course arbitrary.
