Description

[Detailed description of the invention] (a) Technical field of the invention The invention relates to a fixing structure for opening/closing plates such as front decorative panels provided in electronic devices, desktop terminals, etc. This invention relates to a fixing structure for an opening/closing plate that solves problems caused by static electricity and the like by forcibly bringing contact fittings into contact with the operation panel surface.

(b) Background of the Technology In recent years, as the performance of various electronic devices has improved, fluctuations and deterioration of characteristics due to the effects of static electricity noise have become a problem. In order to counteract this static electricity noise, there is a strong demand for the development of a good contact structure between an opening/closing plate such as a front decorative panel that can be opened and closed, and the main body of a desktop terminal.

(c) Problems with the Prior Art FIG. 1 is a perspective view of the main parts for explaining the conventional fixing structure of the opening/closing plate.

The operating panel surface 2 of the terminal main body 1 of a desktop terminal used in an environment such as an office has a structure in which the front decorative panel 3 can be opened and closed with a hinge 4 so that the operating panel surface 2 is not touched by hands except when adjustment is required. , and a magnetic rubber plate 5 is attached to the back surface of the opposite end to which the hinge 4 is attached of the front decorative board (hereinafter sometimes referred to as a decorative decorative board or an opening/closing board). is magnetically fixed to the operation panel surface of the terminal main body 1. However, in such a fixed structure, the decorative board 3 is grounded by the contact of the hinge 4, but in this case, the decorative board 3 and the terminal main body 1 are
The electrical connection is incomplete and does not provide reliable grounding. Therefore, it is insufficient to cover the front surface of the device with an opening/closing plate made of a metal plate to also serve as a shield for this surface. Furthermore, since the magnetic rubber plate 5 does not have electrical conductivity, it does not make ground contact. Therefore, when the magnetic rubber plate 5 is covered with a wire mesh or the like and grounded, the above-mentioned operation in which the magnetic rubber plate 5 comes into contact with the magnetic rubber plate 5 is necessary. Each of these has its own problems, such as the need to peel off the paint on the opposing surface of the panel surface 2 to create a metal surface, or to connect the terminal body 1 and the front decorative panel 3 with strap wires.

(d) Purpose of the invention In view of the above-mentioned conventional problems, the purpose of the invention is to provide a fixing structure for an opening/closing plate in which a grounding connection can be forcibly made by closing the front decorative plate. It is something.

(e) Structure of the invention The fixing structure of the opening/closing plate according to the invention, as shown in FIGS. 2 and 3, includes a contact fitting 7 provided to protrude toward the back side of the opening/closing plate 6, and a terminal device. The opening/closing plate 6 is supported by a support shaft 11 provided on the side of the main body 1.
a pressing metal fitting 10 supported so as to be swingable in a direction parallel to the opening/closing direction; and a contact spring 9 provided to protrude inward from the back surface of the operation panel surface 2.
When the opening/closing plate 6 is closed, the contact fitting 7 on the opening/closing plate 6 first comes into contact with the contact spring 9 on the operation panel surface 2 in a manner that pushes it up, and then When the contact fitting 7 comes into contact with one arm of the pressing fitting 10 and swings it, the other arm of the pressing fitting 10 contacts the contact spring 9 in a manner that pushes it down. It is characterized by:

(f) Embodiments of the invention Examples of the fixing structure of the opening/closing plate according to the invention will be described in detail below with reference to the drawings.

Figure 2 is a perspective view of essential parts for explaining one embodiment of the fixing structure of the opening/closing plate according to the present invention, and Figures 3 a and b.
FIG. 2 is a side cross-sectional view of a main part for explaining its operation. In Figures 2 and 3, the fixing structure of the opening/closing plate of this invention is the same as in Figure 1, and includes the terminal main body, operation panel surface, front decorative plate, hinge, etc. It is characterized by an improved structure. Therefore, the same reference numerals as in FIG. 1 are given to the parts other than the fixing structure of the front decorative panel, and the explanation of these parts will be omitted here. The fixing structure of the opening/closing plate that characterizes the present invention is that a convex contact fitting 7 made of a conductive metal material is attached to the inner surface of the opposite end of the front decorative plate 6 from which the hinge 4 is attached. Then, a contact fitting insertion hole 8 is bored at a position corresponding to the contact fitting 7 on the operation panel surface 2, and a contact spring 9 made of a conductive metal material such as phosphor bronze is fixed to the internal front surface of the terminal main body 1. In addition, the contact spring 9 on the inner upper surface of the terminal main body 1
A press fitting 10 is provided at a position corresponding to the support shaft 11 so as to be able to swing at a predetermined angle.

Thus, when the front operation plate 6 is closed in the direction of arrow A as shown in FIG. 3a, the contact fitting 7 comes into contact with the contact spring 9 and pushes up the spring 9, as shown in FIG. 3b. When one of the arms of the press fitting is pressed in the direction of arrow B, the press fitting 10 rotates in the direction of arrow C, and the other arm moves in the direction of arrow D to press the contact spring 9 and release the contact spring. 9 is structured to ensure reliable contact and grounding with the contact fitting 7. In this case, if a groove 12 is provided in the contact fitting 7 at the contact position of the contact spring 9, the effect of a stopper can be obtained.

This fixing structure is such that when the front decorative panel 6 is closed to a certain extent, the contact spring 9 on the side of the terminal main body 1 that has contacted the contact fitting 7 on the front decorative panel 6 closes the front decorative panel 6. When completely closed, push metal fitting 10
Since the contact fitting 7 is pressed sideways by the contact spring 9, the degree of contact between the contact spring 9 and the contact fitting 7 is significantly improved.

(g) Effects of the device As is clear from the above explanation, the fixing structure of the opening/closing plate according to the present invention can provide the same grounding effect as when the entire surface of the operation panel is covered with a shielding wire mesh, etc. Therefore, it greatly contributes to improving the characteristics of the device. Note that this structure is applicable not only to the front surface but also to opening/closing plates provided at any location on each surface.
