Description

DETAILED DESCRIPTION OF THE INVENTION Industrial field of application The present invention relates to a socket for a lamp for illumination, which is used for an indoor / outdoor signboard, an interior panel, an electronic display board, and the like.

Problems to be Solved by Conventional Techniques and Inventions Conventionally, the socket of the lamp for lighting has a type in which the socket is fitted from the outside into a mounting hole formed in a mounting plate (panel) at a place where it should be installed. However, this type of product had a major drawback in work efficiency because it required wiring work in the field after mounting the socket on the panel.

The present invention has been devised to eliminate the above-mentioned conventional drawbacks, and an object thereof is to provide a new socket in which the socket is fitted into the panel from the inside.

Means for Solving the Problems This method has a feature in that the wiring work can be performed in the factory by fitting the socket into the mounting hole of the panel from the inside. A ring-shaped flange 3 is provided on the outer periphery of a main body 1 made of a soft resin, which is loaded with, and an outer peripheral groove 4 for fitting a mounting hole is formed on the outer peripheral surface of a position directly above the ring-shaped flange 3. The outer peripheral groove 4 is formed such that the groove bottom 4a is gradually deeper toward the upper side and the upper wall 4b is downwardly inclined to form an acute angle, and the upper outer peripheral surface 1a of the outer peripheral groove 4 is a truncated cone. The gist is the configuration that has been formed into a shape.

In this case, since the main body 1 is made of soft resin and the upper part is frustoconical, the upper part of the main body 1 can be easily pushed into the mounting hole b of the mounting plate a. Hole b
, The inner peripheral end surface of the mounting hole b engages with the outer peripheral groove 4,
Moreover, the outer peripheral groove 4 is a taper groove in which the groove bottom 4a gradually becomes deeper toward the upper side, and the upper wall 4b is formed in a slope having an acute angle toward the lower side. The inner peripheral end surface of the mounting hole b has a bottom groove 4a. Also, since it is closely attached to the upper wall 4b, a very advantageous waterproof effect is obtained, and at the same time, the mounting hole b is fitted from the inside, there is no need to perform wiring work on site, and wiring is done beforehand at the factory and simply on site. The work can be completed simply by inserting the socket.

EXAMPLE An example in which a concrete structure of the present invention is shown in the drawings will be described below. 1 is a main body made of a soft resin such as a sunplane, 2 is a mouthpiece installed in the main body 1, and 3 is an outer periphery of the main body 1. The annular collar that has been installed has an outer peripheral groove 4 directly above the annular collar 3.
The outer peripheral groove 4 is formed such that the bottom groove 4a is a taper groove that gradually becomes a deep groove upward and the upper wall 4b is formed in an inclined surface that forms an acute angle downward. The upper part is formed in a truncated cone shape.

In the figure, 5 indicates a lead wire.

Effect of the Invention As described above, the present invention has an annular collar 3 protruding from the outer periphery of a main body 1 made of a soft resin having a mouthpiece 2 loaded therein, and a mounting hole formed on the outer peripheral surface of a position directly above the annular collar 3. An outer peripheral groove 4 for fitting is formed, and the outer peripheral groove 4 is formed as a taper groove having a groove bottom 4a which gradually becomes an upward deep groove and an upper wall 4b which is formed as an inclined surface which becomes an acute angle downward. Further, the upper outer peripheral surface 1a of the outer peripheral groove 4
In the mounting state of the socket, the inner peripheral end surface of the mounting hole is in close contact with the bottom groove 4a and the upper wall 4b of the outer peripheral groove 4 and the outer peripheral groove 4 is in close contact with the back side. Not only can a stable and strong wearing state be obtained, but a remarkably waterproof effect can be obtained.In particular, the present invention is one that is fitted into the mounting hole from the inside so that the wiring does not interfere when fitting, There is no need to perform wiring work on site,
This has the advantage that the work can be completed by simply fitting the wires that have been wired in the factory in advance at the site, and an extremely advantageous effect that contributes to the improvement of the work efficiency can be obtained.
