Description

[Detailed description of the invention] [Table of contents] - Overview - Field of industrial application - Prior art - Problems to be solved by the invention - Means for solving the problems - Effects - Examples - Effects of the invention [Summary] For an electronic device mounted with multiple shelves that accommodate a group of printed board packages, equipment units other than the shelves are installed in the empty space of the shelf installation opening.

[Industrial application field]

The present invention relates to a device unit mounting structure for an electronic device that includes a plurality of shelves that accommodate printed board packages.

[Conventional technology]

BACKGROUND ART In communication devices and other electronic devices, the necessary number of shelves housing a large number of printed board packages having various functions are assembled into a rack device as functional units to constitute the electronic device. Such a shelf is attached to each opening of a shelf attachment plate having shelf attachment openings, and this shelf attachment plate is attached to a rack. The dimensions of such racks and shelf mounting plates are usually standardized, and the shelf mounting plates are provided in multiple stages relative to the rack.

After all necessary shelves are attached to this shelf attachment plate, there may remain a shelf attachment opening where no shelf can be attached. On the other hand, such electronic devices include
Equipped with push buttons for operation, various indicator lamps, etc.

[Problem that the invention seeks to solve]

In conventional electronic devices, operation pushbuttons, indicator lamps, etc. are installed in locations other than the shelf attachment part of the rack, which requires installation space around the rack. If a suitable location cannot be provided within or around the rack, it must be installed at a separate location, and wiring work is also troublesome.

An object of the present invention is to eliminate the drawbacks of the above-mentioned prior art and provide a device unit mounting structure for an electronic device that allows device units other than the shelf, such as operation buttons and indicator lamps, to be mounted without creating a new installation space. .

[Means for solving problems]

In order to achieve this object, the present invention provides for mounting equipment units other than the shelf to an electronic device equipped with a shelf mounting plate having a plurality of shelf openings for mounting a shelf accommodating a group of printed circuit board packages. In the device unit mounting structure for the electronic device, the device unit is attached to the remaining shelf openings after all the shelves to be attached to the electronic device are attached to the plurality of shelf openings.

[For production]

Attach the equipment unit to the opening for the shelf that is now empty after the shelf is installed.

〔Example〕

FIG. 1 is a perspective view of an embodiment of the invention. The shelf mounting plate 1 has two shelf openings 15, and the shelf 2 is attached to one of the shelf openings. shelf 2
A large number of printed board packages 3 are accommodated therein, and each printed board package 3 is connected to a backboard 4 provided on the back side of the shelf mounting plate 1 via a connector (not shown). 5 is a ventilation hole. Such shelf mounting plates 1 are stacked and attached to the rack, for example, in three stages, depending on the number of shelves required for the electronic device and the standards of the rack (not shown) constituting the electronic device. At this time, if the total number of shelves required for the electronic device is five, one shelf opening 15 remains as an empty space.

Corresponding to the size of this shelf opening 15, an operation display panel frame 8 having operation buttons 6, display lamps 7, etc. provided on its surface is formed. A connection terminal unit 10 having a terminal 11 connected to each operation button 6 etc. via a wrapping wire 9 is fixed inside the operation display panel frame 8 .

Such a connection terminal unit 10 and operation display panel frame 8
are integrated to form an operation display unit 14, and this operation display unit 14 is attached to the shelf opening 15 remaining as an empty space. The operation display unit 14 is screwed and fixed to the shelf opening 15 of the shelf mounting frame 1 through the mounting hole 13 of the operation display panel frame 8 provided in alignment with the shelf mounting screw hole 12 provided on the shelf mounting plate 1. be done. Each terminal on the back side of the connection terminal unit 10 is connected to the wiring pattern of the backboard 4 of each shelf 2 by a wrapping wire.

〔Effect of the invention〕

As explained above, in the device unit mounting structure for an electronic device according to the present invention, a mounting frame for a device unit such as an operation display unit is formed in accordance with the shape of the shelf opening, and this is attached to the shelf opening. Since it is installed in the empty space of the electronic equipment, the wasted space of the rack equipment that makes up the electronic equipment is effectively used, and equipment units can be installed without requiring new space, resulting in smaller equipment, reduced installation space, and The wiring length can be shortened.
