Description

[Detailed Description of the Invention] The present invention relates to a mounting device for a fluorescent display tube in which terminals are soldered onto a printed circuit board so that it can stand on its own, and can be installed easily and inexpensively without using fasteners such as screws. The purpose of the present invention is to provide a device that can be removed and removed.

As shown in FIGS. 1 and 2, a fluorescent display tube 2 is mounted on a printed circuit board 1 with soldered terminals.
The upper part of the frame is held by being sandwiched between a fixture 3 made of a resin molded product, and this fixture 3 is fixed to a part of another frame 4 using fasteners such as screws 5, thereby making it possible to measure. However, in this case, it requires work to fasten with screws, so the cost and
This method has the disadvantage of requiring a lot of man-hours.

The present invention eliminates the above-mentioned drawbacks by using a fixture with elastic locking pieces to hold the fluorescent display tube between the front panel and the front panel. An example of this will be described below with reference to FIGS. 3 and 4. Components in the figure that are the same as those in FIG. 1 are designated by the same numbers and will be explained.

In the figure, reference numeral 11 denotes a front panel, and L-shaped holding parts 12, 12 are provided on the back side of the top plate so as to face each other. Further, the front panel 11 has an opening 13 in the front plate portion corresponding to the fluorescent display tube 2, and the fluorescent display tube 2 is positioned below the opening 13.
A plurality of protrusions 14 are integrally provided to support the front and back and up and down directions. Further, reference numeral 15 denotes a fixture made of a resin molded product, which includes a pair of elastic locking pieces 1.
5a, 15a, a protruding piece 15b that holds the fluorescent display tube 2 in the front-back direction together with the protrusion 14, and a stopper piece 15c for attaching the fixture 15 to the holding parts 12, 12 together with the locking pieces 15a, 15a. It becomes more.

Next, to explain the installation of the fluorescent display tube 2, the fluorescent display tube 2 with the terminals soldered to the printed wiring board 1 is placed on the stepped portion of the protrusion 14, and the fluorescent display tube 2 is supported from below and from the front. do. In this state, the fixture 15 is inserted between the pair of holding parts 12, 12 to lock the locking pieces 15a, 15a to the rear ends of the holding parts 12, 12, respectively. Along with this locking, the stopper piece 15c
2, the fixture 15 holds the holding parts 12, 12 between the holding parts 12, 12 between the locking pieces 15a, 15a and the stopper piece 15c.
12, at the same time, the protruding piece 15b of the fixture 15 comes into contact with the back surface of the fluorescent display tube 2, and as a result, the fluorescent display tube 2 is held by the protrusion 14. Therefore, according to this configuration, the fluorescent display tube 2 can be attached by simply providing the fixture 15 separately and inserting the fixture 15 between the holding parts 12, 12, and the work efficiency is extremely high. Becomes good.

As described above, according to the present invention, a fluorescent display tube can be attached between the fixture and the protrusion provided on the front panel by simply inserting the fixture between the holding parts, which improves work efficiency. It is possible to achieve improvements and reduce the total cost, and it can be easily removed when replacing the fluorescent display tube, so it has extremely great practical value.
