[Industrial application field]

The present invention relates to a novel mounting structure for a door of a housing that houses electronic communication equipment.

[Conventional technology]

Recent electronic communication devices have diversified systems, and it is required to provide an operation panel on the front surface of the housing for monitoring and operating the equipment housed inside with the housing door closed. This panel is often provided in the central part of the housing, and as a result, as shown in FIG. 4, the door of the housing 1 sandwiches the operation panel 2 provided in the central part and is divided into two upper and lower parts. The number of cases of being divided into 4 is increasing.

[Problems to be solved by the device]

Each of the doors 3 and 4 is rotatably supported by inserting a support pin of a hinge mechanism provided in each of the upper and lower corners into a corresponding support hole provided on the housing side. It has a structure that In this case, since the support hole on the side of the operation panel 2 is formed in the chassis of the panel itself, when the operation panel is removed for repair or adjustment, one hinge is supported by this. There was a drawback that the doors 3 and 4 would inevitably come off.

The present invention solves the above problems in the prior art, and an attachment mechanism capable of supporting a door vertically divided by an operation panel provided at the center of a housing without depending on the operation panel. The purpose is to provide.

[Means for Solving the Problems]

The purpose is to attach the operation panel to the center of the front surface of the housing with the front surface exposed, and to provide a door on the front surface of the housing in each of the upper and lower areas of the operation panel, and to use a conductive rubber between the door and the housing. In the housing for electronic communication equipment configured to cover the electronic equipment unit housed inside, and extending in the width direction in each region of the front surface of the housing divided vertically by the operation panel. The existing first beam is fixed, the second beams extending in the width direction are also fixed to the upper and lower edges of the housing, and the first and second beams are provided with a hinge mechanism so that the adjacent first beams are adjacent to each other. And a pair of second beams, each door being supported so as to be openable and closable.

Hereinafter, the present invention will be described in more detail with reference to the preferred embodiments shown in the drawings.

〔Example〕

As shown in FIG. 1, in a housing 11 to which the present invention is applied, mounting screw holes 23 are drilled at a predetermined pitch on both left and right sides of the front surface of the main body.

An operation panel 12 is fixed to the front surface of the housing 11 by means of the screw holes 23 in the central portion of the housing 11 with screws 25. Using the screw holes 23 above and below the operation panel 12, a pair of first beams 20a for attaching a door to the front surface of the housing 11 are provided.
20b is fixed. As shown in FIG.
These first beams extend so as to cross the width of the housing 11 and project forward by the thickness of doors 13 and 14 described later.

The present invention relates to a mounting mechanism for freely opening and closing doors 13 and 14 that individually cover electronic device units that are divided into upper and lower regions and are mounted, which will be described below.

A second beam 26a protruding forward by a distance corresponding to the thickness of the door 13 is fixed to the upper edge of the housing 11, and a hole 28 is provided in one corner of the lower surface (right side in the illustrated example). ing. The first beam 20a is also provided with a hole 29 at the right corner on the same axis as the hole 28.

Holes 30 and 31 are provided in the door 13 at positions corresponding to these holes 28 and 29, respectively.

To install the door 13, first place the second beam in the hole 29 of the first beam 20a.
The hinge pin 22 is set as shown in the figure, and the tip 22a is projected upward. On the other hand, the hinge pin 21 of the same shape is set also in the upper hole 30 of the door 13, and in that state the second beam
The tip portion 21a is inserted into the hole 28 of 26a. Next, the door 13 is moved downward to insert the lower hole 31 into the hole 29 of the first beam 20a of the frame body. If the length of the tip portion 21a of the hinge pin and the vertical movable range of the door 13 are set appropriately, the hinge pins 21 and 22 are stably held without coming off from the upper and lower holes 30 and 31, and the door 1
3 is pivotally supported.

The lower door 14 is also pivotally supported between the second beam 26b and the first beam 20b provided along the lower edge of the frame body 11 by a combination of a hole and a hinge pin having substantially the same structure. .

Further, in the present invention, the tube-shaped conductive rubber 27 is attached to the inner surface of each door 13 and 14 through the metal fittings 24 along the four sides thereof. As shown in FIG. 2, these conductive rubbers 27 come into contact with the beams 20a, 20b, 26a, 26b and both side areas on the front surface of the housing 11 when the door is closed, so that the door and the housing are not separated from each other. The electrical conduction of is improved and the impact is mitigated, and the shield effect is improved.

[Effect of device]

In the present invention, the hinge pin that supports each of the doors divided into upper and lower parts by the operation panel is not the operation panel itself as in the prior art, but its position can be freely changed according to the size of the operation panel. Since it is attached to the door, even if the operation panel is removed for maintenance / adjustment, there is no problem in supporting the door, and the work can be easily performed.

Moreover, since the conductive rubber is attached to the inner surface of the door so that the conductive rubber can be brought into close contact with the beam, the electrical continuity between the door and the case is improved and the sealing property is improved.
