Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mounting device for liquid crystal display boards, etc. used in telephones and other equipment.

BACKGROUND TECHNOLOGY In general, when installing a liquid crystal display board, etc. in a telephone or other equipment, the liquid crystal display board 2 is placed inside a case 1, as shown in FIG.
Both ends of the are pressed and fixed by elastic bodies 4 and 5 provided between the liquid crystal display board 2 and the printed circuit board 3, respectively, and the electrical connection between the two is made through one of the elastic bodies 4, which is electrically conductive. Accordingly, the contact points 6 and the printed circuit board 3 provided on the liquid crystal display panel 2, respectively.
In many cases, the contacts 7 provided at the terminals are configured to be electrically connected to each other.

When a pushbutton device such as a dial key is installed close to the liquid crystal display board 2, a cap-shaped elastic rubber 9 is attached to the printed circuit board 3 as shown in FIG. 4, regardless of the installation of the liquid crystal display board 2. , by pressing the push button 10, the contact 11 provided on the inner ceiling of the elastic rubber 9 comes into contact with the contact 12 provided on the printed circuit board 3, and the liquid crystal display board 2 is operated as a switch. It is installed close to the

Problems to be Solved by the Invention As described above, in the conventional device, even when a push button device such as a dial key is installed nearby, the liquid crystal display panel 2 is installed independently of the push button device. A separate elastic body 5 is always required, and the overall assembly is troublesome and costly.

The object of the present invention is to eliminate the above-mentioned conventional drawbacks and to provide an excellent mounting device for a liquid crystal display panel, etc., which has a simple structure and is inexpensive.

Means for Solving the Problems In order to achieve the above object, the present invention forms a protrusion integrally at the end of a flat plate of elastic rubber constituting a push button device such as a dial key that is mounted in close proximity. The structure is such that a liquid crystal display panel or the like is directly pressed and fixed to the case side.

Therefore, according to the present invention, there is no need for a special elastic body for separately pressing and fixing the liquid crystal display panel etc. to the case side, and the overall structure is simplified and reduced in cost.

Embodiment FIGS. 1 to 3 show an embodiment of the present invention, in which 21 indicates a display window formed in the case 21 of the telephone, and 23 indicates a display window 22.
a projection 24 integrally formed on the inner surface of the case 21 facing the outer periphery of the display window 22;
is a boss 26 integrally formed on the inner surface of the case 21.
27 is a printed circuit board which is fastened to the boss 25 with screws, and 27 is the contact 28, 29 for electrically connecting the contact 28 of the liquid crystal display panel 24 and the contact 29 formed on the printed circuit board 26 to each other. A conductive elastic body provided between the display windows 2 and 30 is a display window 2.
A through hole for attaching a push button is formed in the case 21 adjacent to 2, a push button 31 is inserted into the through hole 30 so as to be able to come in and out from the inside of the case 21, and 32 is attached to the printed circuit board 26; An elastic rubber member 33 having a cap-shaped portion at an opposing position is attached to the inner ceiling of the cap-shaped portion of the elastic rubber 32, and when the push button 31 is pressed, it contacts the contact point 34 formed on the printed circuit board 26, and functions as a switch. A contact point 35 is formed integrally with the end of the flat plate portion of the elastic rubber 32 and is interposed between the liquid crystal display board 24 and the printed circuit board 26 to press and fix one end of the liquid crystal display board 24 to the protrusion 23. This is the protrusion.

In the above embodiment, the liquid crystal display plate 24 is arranged on the case 21 facing the display window 21 formed on the case 21.
It is elastically pressed and fixed to the inner surface of the case 21 by a protrusion 35 formed on the elastic body 27 and the elastic rubber 32. Therefore,
According to the above embodiment, the elastic body 5 is separately provided as in the conventional case.
It has the advantage of not requiring That is, according to the above embodiment, the protrusion 35 is integrally formed on the elastic rubber 32 of the push button device provided adjacently, and the protrusion 35 is interposed between the liquid crystal display board 24 and the printed circuit board 26. There is no need to prepare a separate elastic body for this purpose, and the overall structure has the advantage of being easier and cheaper.

Effects of the invention As is clear from the above embodiment, the present invention forms a protrusion integrally at the end of the flat plate of the elastic rubber constituting the push button device which is mounted in close proximity, and connects the protrusion to the liquid crystal display panel. The liquid crystal display board is interposed between opposing printed circuit boards and is press-fixed to the inner surface of the case, and the overall structure does not require a separate elastic body for press-fixing. It has the advantage that it is simple and can be constructed at low cost.

In the embodiment, a mounting device for a liquid crystal display board has been described, but other display boards can be constructed in the same manner.
