Abstract

PURPOSE:To improve the surface intensity of a lamp cover by constituting an outer hull with a cover arranged with a display element and a body provided with a terminal section connected to an electric wire from the outside, and forming a reflecting plate reflecting the light of the display element to the front side integrally with the cover. CONSTITUTION:An apparatus main body A is constituted of a cover 1 and a body 10, the cover 1 is made of thermoplastic resin, and an opening section 3 for fitting a translucent lamp cover 2 is formed on the front face. A reflecting plate 4 is formed integrally with the cover 1 on the back side of the cover 1, and a neon lamp 5 serving as a display element and a resistor 6 are fitted on the front side of the reflecting plate 4. The reflecting plate 4 is made slightly larger than the neon lamp 5, and slant faces 7 are formed on both side of the neon lamp 5. The backward light of the neon lamp 5 is reflected to the front side by the nearly U-shaped reflecting plate 4 expanded with the cross section, thus the surface of the lamp cover 2 is made brighter.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to the structure of an embedded pilot lamp that is embedded in a wall surface or the like.

[Prior Art] A neon lamp is used as a display element of this type of embedded pilot lamp for position indication, and the light from this neon lamp is irradiated through a front lamp cover.

[Problems to be Solved by the Invention] In such conventional examples, light is absorbed due to the brown metal parts on the back of the neon lamp and the dark-colored body, resulting in a bright and shiny state on the surface of the lamp cover. There was a lock called Naru.

The present invention has been provided in view of the above-mentioned points, and is an embedded pilot lamp for the purpose of making the surface of the lamp cover brighter by directing the light of the display element to the lamp cover without loss. It provides:

[Means for Solving Problem 11] In the present invention, the outer shell is composed of a cover on which a display element is arranged, and a body provided with a terminal part connected to an electric wire from the outside, and the light from the display element is directed to the front side. A reflector plate is integrally formed with the cover to reflect the light.

[Function] The light from the display element is reflected to the front side by the reflector,
This makes the surface of the lamp cover shine brighter.

[Example] An example of the present invention will be described below with reference to the drawings. 1st
In Figures to Figures 3, the instrument body A includes a cover 1 and a body 1.
It consists of 0. The cover 1 is made of thermoplastic resin, and has an opening 3 formed on the front surface for mounting a light-transmitting lamp cover 2 thereon. A reflector plate 4 is formed integrally with the cover 1 on the back side of the cover 1, and a neon lamp 5 and a resistor 6 as display elements are attached to the front side of the reflector plate 4. As shown in FIG. 1, it is formed slightly larger than the neon lamp 5, and slopes 7 are formed on both sides of the neon lamp 5.

Therefore, the light emitted from the neon lamp 5 toward the rear is reflected to the front side by the substantially U-shaped reflecting plate 4 whose cross section is enlarged, thereby making the surface of the run 1 cover 2 brighter. In addition, since the reflector plate 4 is formed integrally with the cover 1, the cover 1
The surface of the lamp cover 2 may be painted in the same color, but it may also be painted in a white color to reflect more light.Also, the sloped surface 7 can reflect more light from the neon lamp 5, increasing the brightness of the surface of the lamp cover 2. can be made more.

Elastic locking pieces 8 are integrally formed on both sides of the back surface of the lamp cover 2, and these locking pieces 8 are connected to the opening 3 of the cover 1.
It can be attached to and detached from the edge of the camera. Moreover, elastic fitting pieces 9 for fitting with the body 10 are formed at both ends of the back surface of the cover 1. Incidentally, the instrument main body A is used, for example, as a position indicator, and is installed on a wall surface or the like. The cover 1 is detachably attached to a mounting frame for a ready-made wiring device, and a pair of protrusions 11 are protruded from both ends of the cover 1 for attachment to an insulating mounting frame. Recessed part 12 for attaching to the mounting frame
is the provision.

The body 10 has an oval structure including a terminal plate 13 to be connected to an electric wire inserted from the outside, a locking spring 14 for elastically contacting the conductor of the electric wire to the terminal plate 13, and a release button for releasing the conductor of the electric wire. A terminal section is provided. An insertion hole 15 into which the fitting piece 9 of the cover 1 is inserted is formed at both ends of the body 10, and as shown in FIG. By locking, the body 10 and the cover 1 are removably coupled. In this way, cover 1 and body 10
The lamp cover 2 can be fitted to the cover 1 with one touch, and the lamp cover 2 can also be fitted to the cover 1 with one touch, making the assembly process easy.

By the way, as shown in FIG. 4, two ribs 16 are integrally formed on the back surface of the reflecting plate 4.
6 has a slit 17 formed therein. This slit 1
7, each lead wire 5a, 6a of neon lamp 5 and resistor 6
is placed. A U-shaped portion 20 at the base of the contact spring 18, where the contact piece 19 at the tip contacts the upper surface of the center piece 13a of the terminal board 13, is press-fitted into the recess 21 of the cover 1 from the back side. When the contact spring 18 is press-fitted into the cover 1, the contact spring 18, the neon lamps, and the lead wires 5a, 6a of the resistor 6 are connected in contact with each other to obtain electrical continuity. Then, when the cover 1 and the body 10 are combined, the contact spring 18 is activated by the center piece 13a of the terminal plate 13.
come into contact with.

[Effects of the Invention] As described above, in the present invention, the outer shell is formed into an ellipse by the cover in which the display element is arranged and the body provided with the terminal part connected to the electric wire from the outside, and the light from the display element is directed to the front side. Since the cover is integrated with a reflector plate that reflects the light from the display element to the front side, it has the effect of making the surface of the lamp cover shine brighter. It is something to play.
