Description

[Detailed Description of the Invention] The present invention relates to sockets for glow lamps, fluorescent lamps, etc.

Conventionally, for example, the installation of the glow socket body was
It was usual to attach metal fittings directly to the lighting fixture body, or to attach metal fittings to the lighting fixture body, respectively, with screws or the like.

However, such a mounting method using screws or the like not only requires a troublesome tightening operation but also requires parts such as screws, resulting in high costs.

The present invention has been made to eliminate the above-mentioned drawbacks of the prior art, and its object is to provide a socket that can be easily installed with a one-touch fitting operation.

The configuration of the present invention will be described below with reference to embodiments shown in the drawings.

What is shown in FIGS. 1 to 3 is an example of a glow socket, and the socket body is made of resin. As shown in the figure, two or more protrusions 2 are provided on the mounting surface 3 of the main body 1 at the same height on the left and right sides. The protrusion 2 is made of resin, and the tip of the leg 2a is an enlarged head 2b.
Further, the leg portion 2a of this protrusion 2 has a height corresponding to the thickness of a mating member 4, which will be described later. Reference numeral 5 denotes a small protrusion provided approximately at the center of the mounting surface 3. At the bottom of the socket body 1 located above this small protrusion,
For example, a rectangular through hole 6 is formed in the horizontal direction along the mounting surface 3.
A slit 7 which is open at one end and communicates with the through hole 6 is provided. The slit 7 is chamfered so that it becomes narrower from the opening side toward the back wall.

What is shown in FIG. 4 is a mating member 4 to which this socket is attached, and as shown in the figure, its mounting surface 8 has fitting holes corresponding to the protrusions 2, 2 and small protrusions 5 provided on the mounting surface 3 of the socket body 1. 9, 9 and 10. The fitting hole 9 includes an enlarged hole 9b through which the enlarged head 2b of the protrusion 2 can be inserted, and an enlarged hole 9b that extends in the insertion direction of the socket body 1 continuously from the enlarged hole 9b, and the protrusion 2.
The long hole 9a has a width approximately equal to the diameter of the leg portion 2a. This counterpart member 4 is a metal fitting that is formed as a part of the lighting fixture body or is attached to the fixture body. To attach the socket body to the mating member, first position the back side A of the socket body 1 on the end face B side of the mating member 4, and simultaneously attach the enlarged heads 2b, 2b of the protrusions 2, 2 of the socket body 1 to the mating member. 4 into the enlarged holes 9b, 9b of the fitting holes 9, 9. Then, the socket body 1 is slid toward the end face C side of the mating member 4. As a result, the socket main body 1 is guided by the fitting relationship between the legs 2a, 2a of the protrusions 2, 2 and the elongated holes 9a, 9a of the fitting hole 9, and one end surface of the small protrusion 5 eventually reaches the end surface of the mating member 4. Once they come into contact, the slide will stop. At this point, the socket body 1 is further forcibly slid. Then, as shown in FIG. 5, the bottom surface of the thin socket body 1 on the side of the small protrusion 5 bends toward the through hole 6 and the slit 7, and the small protrusion 5 fits into the fitting hole 10 of the mating member 4. At the same time protrusions 2, 2
The legs 2a, 2a of the socket come into contact with the ends of the elongated holes 9a, 9a, and the socket body 1 is brought into contact with the mating member 4.
Fixed. Note that it is even more secure if the number of these protrusions is two or more.

As explained above, according to the present invention, the elasticity of the resin and the protrusion can be improved by simply pushing and sliding the resin protrusion into the fitting hole of the mating member without using screws or the like. The attachment of the socket body is reliably and stably achieved by the close engagement of the enlarged head and legs of the socket to the wall of the fitting hole. Further, since no screws or the like are required, the number of parts is small and the product can be provided at low cost.
