Description

[Detailed Description of the Invention] The present invention relates to a lighting fixture with a socket cap, and in particular relates to the structure of the socket cap attachment in which the socket cap is attached to the socket mount.

Conventionally, socket caps for lighting fixtures with socket caps are manufactured by attaching a pair of springs to the socket mounting base, or by processing a pair of cuts and bends in the socket mounting plate, and utilizing the spring properties of the socket cap from the inside of the socket cap. , holding the socket cap.

In this type of socket cap holding structure, in the case of the former spring, the spring attached to the socket mount is usually fixed, and the positioning of the spring in the mounting direction tends to be uncertain, and the spring shape is complicated. Therefore, the mounting and processing properties of the spring are poor, and as a result, the socket cap is often not installed parallel to the socket mount, which causes problems when attaching and detaching the lamp, and also makes the lamp unsightly.

In addition, in the case of the latter cutting and bending process, due to constraints such as the lamp socket, cutting and bending is only possible with a pair of processes on both sides of the socket mounting plate. In many cases, they cannot be installed parallel to each other, and the shape of the socket mounting plate is complicated, so the workability during processing and assembly is poor, and like the former, there are disadvantages in terms of labor saving, lamp attachment/detaching, and design. It was a problem.

This proposal solves the above-mentioned drawbacks by forming a step on the socket mounting base on which the socket and the socket mounting plate with the blind cover are attached, and providing a socket cap with a cut groove that engages with the step. The socket is attached through the cut groove, the socket is housed, and one end of the socket cap is closed with a blind cover, thereby simplifying the structure and preventing the socket cap from being installed crookedly, thus ensuring a structure that does not spoil the aesthetic appearance. A lighting fixture with a socket cap is provided.

The present invention will be explained below with reference to the drawings.

In the figure, 1 is the main body of the lighting device, 2 is a socket mount with an inverted Fuji-shaped cross section attached to both ends of the main body 1 (only one end is shown), and both sides 4 of the tip 3 are attached along the long direction. A stepped portion 5 is formed.

6 is a threaded hole provided in the center of the tip 3; 7 is a socket mounting plate whose bottom 8 is fixed to the tip 3 of the socket I/mounting base 2 with screws 14; A socket 10 into which a lamp (not shown) is inserted is held between the rising pieces 9, and a circular blind lid 11 is erected opposite the socket 10.

Reference numeral 12 denotes a lamp that engages with the stepped portion 5 of the socket mounting base 2 and has a cut groove 13 formed in the peripheral wall having the same length as the longitudinal direction of the stepped portion 5, and is inserted into the socket 10. It is a cylindrical socket cap with both ends open, which has an inner diameter sufficient to accommodate the blind lid 11, and has a length that extends from the blind lid 11 to the lamp base.

In the lighting fixture with a socket cap constructed in this manner, the socket I/cap 12 is arranged so that one end thereof is closed by the blind cover 11 along the stepped portion 5 formed on the socket mounting base 2. Because it is slidingly engaged with the cycad! - Parallelism with the mounting base 2 is not impaired, and inconveniences when attaching and detaching the lamp are eliminated.

Further, the blind cover 11 closes one end of the socket cap 12,
Since the interior is hidden, it is also aesthetically pleasing.

In addition, there is no need to attach a spring for attaching a socket cap to the socket mount 2 or to bend the socket mount plate 7 as in the conventional case, which improves ease of processing and assembly.

Furthermore, even when the end surfaces of the lighting equipment are in contact with each other and used as a connected type, the socket cap 12
Since the lamp can be moved toward the center of the lamp while being inserted into the lamp socket 10, the ease of attaching and removing the lamp is not impaired.

Further, since the socket cap 12 is engaged with the stepped portion 5 of the socket mounting base 12, the socket cap 12
When the sockets 1-10 are engaged and disengaged, unnecessary force is not applied to the sockets 1-10, and the effect of preventing the sockets 10 from moving can be expected.

In addition, in FIG. 3, projections 15 are formed at opposing positions on both side surfaces 4 of the stepped portion 5 of the socket mounting base 2 so that the distance connecting the protruding ends thereof is larger than the width of the cut groove 13 of the socket cap 12. Socket mounting base 2 different from the above embodiment
Since the protrusion 15 acts to spread out the cut groove 13, the socket mounting base 2 and the socket cap 12 are more securely held together.

Furthermore, FIG. 4 shows another embodiment in which the stepped portion 5 of the socket mounting base 5 has a shape with a constricted portion 16 having a square cross section.
This has the effect that sliding can be performed smoothly without coming off from the stepped portion 5.

Since this invention is constructed as explained above, it is possible to simplify the structure of the socket cap mounting part and prevent the socket cap from being bent and mounted on the socket mounting base, thus making it possible to smoothly attach and detach the lamp, and to improve the aesthetic appearance. Accordingly, it is possible to provide an excellent lighting fixture with a socket cap.
