Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a lighting fixture, and particularly to a mounting structure for a lamp socket.

(Prior Art) As shown in FIGS. 6 and 7, for example, the mounting structure of a lamp socket in a conventional lighting equipment has mounting grooves 3 on both sides of a lamp socket 2 having a lamp connection part 1 for connecting a straight tube lamp. A mounting base portion 4 having a lamp socket 2 is provided, and the lamp socket 2
A pair of substantially L-shaped mounting pieces 9 consisting of a vertical piece 7 and a horizontal piece 8 are cut and raised facing each other on the mounting surface 6 of the chassis 5 on which the lamp is mounted, and the lamp socket 2 is inserted between these mounting pieces 9. 10, and a stopper piece 11 is cut and raised between both mounting pieces 9, and the lamp socket 2 is slid in parallel toward the insertion part 10 from the insertion direction shown by the arrow in FIG. Insert and fit both mounting base parts 4 between the vertical pieces 7 of both mounting pieces 9, and fit the horizontal pieces 8 of both mounting pieces 9 into the mounting grooves 3 of the mounting base part 4. Slide the lamp socket 2 into contact with the stopper piece 11 and install it.

(Problems to be Solved by the Invention) In the conventional lamp socket mounting structure as described above, as the first operation for installing the lamp socket 2, as shown in FIG.
It is necessary to slide the lamp socket parallel to the insertion part 10 between the two mounting pieces 9, but at this time, if the parallel slide of the lamp socket 2 is tilted, one of the mounting base parts 4 of the lamp socket 2 will tilt as shown in FIG. Even if the lamp socket 2 is inserted into one mounting piece 9, the other mounting base part 4 may get caught on the end of the other mounting piece 9, and the lamp socket 2 may not be installed at once, making it difficult to perform the socket installation work efficiently. Nakatsuta.

The present invention was developed in view of the above-mentioned problems, and it is an object of the present invention to provide a lighting fixture that allows the lamp socket to be easily inserted between the mounting pieces of the chassis so that the lamp socket can be installed in a single insertion operation. .

[Structure of the idea]

(Means for Solving the Problems) The present invention involves cutting and raising a pair of substantially L-shaped mounting pieces, each consisting of a vertical piece and a horizontal piece, facing each other on the mounting surface of the chassis on which the lamp socket is attached. In a lighting fixture formed by inserting and fitting a lamp socket having mounting grooves on both sides between the vertical pieces of the mounting piece into which the horizontal piece of the mounting piece fits, the lamp socket insertion side of the vertical piece of the one mounting piece is provided. This is an extension of the guide piece.

Furthermore, a guide piece portion is provided on one of the pair of mounting pieces at each mounting location to which a pair of opposing lamp sockets to which straight tube lamps are connected is mounted, one of which faces symmetrically with respect to the lamp center.

(Function) When installing a lamp socket between a pair of mounting pieces, the present invention first places one side of the lamp socket on the inside of the guide piece of one of the mounting pieces, and then slides the lamp socket along the guide piece. By sliding the lamp socket, you can slide it parallelly and insert it between both mounting pieces without tilting the lamp socket.

In addition, when press-forming the mounting pieces at each mounting point of the chassis to which a pair of opposing lamp sockets for connecting straight tube lamps are attached, it is possible to use a common block mold for the mounting pieces at both mounting points. becomes.

(Embodiment) Hereinafter, the configuration of an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

Note that structures that are the same as those shown in FIGS. 6 and 7 are designated by the same reference numerals, and their description will be omitted.

As shown in FIG. 5, lamp sockets 2 to which two straight tube lamps 21 are respectively connected are mounted facing each other at the four corners of a rectangular chassis 5, and lamp sockets 2 for each straight tube lamp 21 are installed in the center. ballast 22
is installed.

On the mounting surface 6 of the chassis 5 to which the lamp socket 2 is attached, as shown in FIGS.
A pair of letter-shaped mounting pieces 9 are cut and bent to face each other, an insertion portion 10 for the lamp socket 2 is provided between the two mounting pieces 9, and a stopper piece is provided between the two mounting pieces 9 on the side opposite to the socket insertion side. 11 is cut out. In addition, a relief part 23 is provided at the edge of the horizontal piece 8 of both mounting pieces 9 on the socket insertion side, and is inclined toward the side opposite to the socket insertion side. A guide piece 24 cut and raised in parallel with the vertical piece 7 extends by a width a on the socket insertion side. As shown in FIG. 5, among the pair of mounting pieces 9 at each mounting location to which the opposing lamp sockets 2 are attached, one mounting piece 9 facing symmetrically with respect to the lamp center (tube axis center line) s is attached. A guide piece portion 24 is provided.

Further, the lamp socket 2 is provided with a lamp connection portion 1 on the opposing surface and a mounting base portion 4 having mounting grooves 3 on both sides.

Then, to attach the lamp socket 2 to the chassis 5, first slide it parallel to the insertion part 10 between the mounting pieces 9 from the socket insertion direction shown by the arrow in FIG.
When the side surface of the lamp socket 2 is placed against the inside of the guide piece part 24 of one of the mounting pieces 9 and slid along the guide piece part 24, the lamp socket 2 slides in parallel without tilting, and both the mounting base parts 4 of the lamp socket 2 is inserted between the vertical pieces 7 of both mounting pieces 9, and the horizontal pieces 8 of both mounting pieces 9 are fitted into the mounting grooves 3 of the mounting base part 4. After this insertion, the lamp socket is further slid. 2 is brought into contact with the stopper piece 11 to complete the installation.

Therefore, when attaching the lamp socket 2, by placing it along the guide piece 24, both mounting pieces 9 can be attached in parallel without tilting the lamp socket 2.
It is easy to insert between the two mounting pieces 9, and can be installed by one insertion operation between both mounting pieces 9. Therefore, it is suitable as a lamp socket mounting structure for automated insertion of the lamp socket 2.

Note that when the lamp socket 2 is installed, the vertical piece 7 of both mounting pieces 9 and the stopper piece 11 are positioned and held in the horizontal direction, and the horizontal piece 8 fitted into the mounting groove 3 of the mounting base 4 is and sashishi 5
Positioning and holding in the vertical direction is performed between the mounting surface 6 and the mounting surface 6 .

Further, a press molding method is used to provide the mounting pieces 9 on the chassis 5, and as shown in FIG. By providing the guide piece 24 on one of the mounting pieces 9 facing symmetrically with respect to s, the block mold used for press forming the mounting piece 9 can be shared, and the cost of the mold can be reduced. That is,
As shown in FIG. 4, it is sufficient to prepare a pair of identical block molds A and set them in a press block mold with their orientation changed by 180°.

[Effect of idea]

According to the present invention, when installing a lamp socket between a pair of mounting pieces, first, one side of the lamp socket is placed inside the guide piece of one of the mounting pieces, and the lamp socket is slid along the guide piece. Since the lamp socket can be slid in parallel without tilting, the lamp socket can be easily inserted between the two mounting pieces in one operation, and the lamp socket mounting work can be carried out efficiently.

In addition, of the pair of mounting pieces at each mounting location where a pair of opposing lamp sockets for connecting straight tube lamps are attached, a guide piece is provided on one of the mounting pieces that faces the lamp center in a symmetrical position. As a result, the block mold used for press-forming the mounting piece can be used in common for both mounting locations, and the cost of the mold can be reduced.
