2. Description of the Related Art Electronic devices, communication devices, and the like housed in a housing housing device, such as a box-shaped housing, are often housed and tested in a cabinet-shaped device, such as a cabinet of test equipment formed in a cabinet shape.

At this time, it is required that the housing housing device be easily attached and detached.

[Conventional technology]

FIG. 4 is a perspective view showing a conventional fixing structure, in which an adjustment component is mounted on the front plate 2 of a housing housing device (for example, a wireless transmitting/receiving device) housed in a box-shaped housing.

It is configured such that an antenna and the like can be attached thereto.

Further, the device bottom plate 3 is provided with a screw hole for fixing to the cabinet type device 5, and a connector for connecting to the cabinet type device 5 is attached to the lower surface of the device bottom plate 3.

Cabinet-shaped equipment housed in a box-shaped cabinet (
For example, on one cabinet side plate 7 of test equipment) 5,
A rectangular insertion window 8 is provided so that the housing housing device 1 can be inserted therein. Inside the cabinet, a middle beam plate 9 for supporting and fixing the housing accommodating device 1 is provided horizontally, and a space for accommodating the housing housing device 1 is provided above the middle beam plate 9.

A partition plate 1 of a space that accommodates this housing housing device 1 is provided.
Desired devices are housed at the back of the cabinet 8 and on the side panels of the cabinet.

An operation panel 14 is attached to the cabinet front plate 6, and on the front side of the cabinet front plate 6, a case housing device and a cabinet type device are installed with the housing housing device 1 housed in the cabinet type device 5. A waveguide 13 is provided to connect the device.

On the other hand, in order to fix the housing housing device 1 to a predetermined position of the middle beam plate 9 with screws, a screw hole 19 is provided at a predetermined position of the middle beam plate 9, through which a fixing screw passes loosely from below. Furthermore, a connector hole 12 is provided for inserting a cable routed below the middle beam plate 9 into a connector of the housing housing device 1.

In order to accommodate the housing housing device 1 in the cabinet type device 5 configured as described above, first, the device front plate 2 is faced to the cabinet front plate 6, and then
The housing housing device 1 is inserted through the insertion window 8 and placed on the middle beam plate 9.

Then, the device side plate is brought into contact with the partition plate 18, and then the housing storage device 1 is shifted at right angles in the direction of the cabinet front plate 6.
The device front plate 2 is brought into contact with the inner surface of the cabinet n-face plate 6 for positioning.

In this state, put your hand under the middle beam plate 9 through the insertion window 8, screw the fixing screw into the screw hole of the bottom plate of the device to fix the housing storage device l to the middle beam plate 9, and then is inserted into the connector of the housing housing device 1 through the connector hole 12.

Further, a set screw is inserted from the front side of the cabinet front plate 6 to connect the waveguide 13 to the housing housing device 1.

[Problem that the invention seeks to solve]

However, with the above conventional structure, the screw holes provided in the bottom plate of the device cannot be visually checked, so the fixing screws must be aligned with the screw holes by hand. Since the housing housing device is moved dynamically and in contact with the partition plate, there is a problem that frictional resistance is large and positioning work is difficult.

[Means for solving problems]

In order to solve the above-mentioned conventional problems, the present invention provides a slide plate attached to the upper surface of the middle beam plate on which the bottom plate of the device slides, and a stopper provided on the side of the partition plate corresponding to the insertion window and abutted by the side plate of the device. A stopper plate is provided on the cabinet front plate side perpendicular to the stopper/slide plate so that the slide plate and the equipment front plate are in contact with each other, and a stopper plate is provided on the lower surface of the middle beam plate in correspondence with the screw holes in the equipment bottom plate. The attached screw retaining metal fitting and the screw part loosely pass through the hole in the acid beam plate, and the screw tip protrudes above the plane formed by the top surface of the slide plate due to the elasticity of the spring. The structure is such that the housing housing device is fixed to a cabinet-shaped device, and includes fixing screws that are vertically held by holding fittings.

[Effect]

According to the above means of the present invention, the slide plate and the stopper/slide plate are made of a material with a small coefficient of friction, such as a Teflon plate, so that the frictional resistance caused by movement of the housing housing device is small. Therefore, the positioning work of the housing housing device is easy.

Further, the fixing screw is constantly lifted upward by spring means. Therefore, when the housing accommodating device is placed on the slide plate, it is pushed by the bottom plate of the device and sinks, and does not become an obstacle to the movement of the housing accommodating device. When the housing housing device is positioned by coming into contact with the stopper/sliding plate and the stopper plate, it is lifted by the elasticity of the spring, and the screw tip portion is automatically inserted into the screw hole in the bottom plate of the device. Therefore, the housing housing device can be easily fixed to the center beam plate by simply turning the fixing screw.

〔Example〕

The present invention will be specifically explained below with reference to illustrated examples. Note that the same reference numerals indicate the same objects throughout the figures.

FIG. 1 is a side sectional view of a housing housing device according to an embodiment of the present invention installed, FIG. 2 is a side sectional view before installation, and FIG. 3 is a perspective view.

As shown in FIG. 3, two elongated plate-shaped slide plates 10 made of a material with a small coefficient of friction, such as Teflon, are fixed to the middle beam plate 9 of the cabinet-shaped device 5. At a position corresponding to the insertion window 8 of the partition plate 1, an elongated plate-shaped slide plate 10 made of a material with a small friction coefficient, such as Teflon, is closely fixed.

Furthermore, a stopper JN 6 A is fixed to the back surface of the cabinet front plate 6 so as to be perpendicular to the stopper/sliding plate 11 .

As shown in FIG. 2, on the middle beam plate 9, the housing housing device 1 is housed in the cabinet type equipment 5, the device front plate 2 is a stopper plate 68, and the device side plate is a stopper/slide plate 11. In the abutting state, a screw hole 19 is bored at a position corresponding to the screw hole 4 in the bottom plate 3 of the device.

Screw holding fittings 20 having a channel shape in side view are fixed to the lower surface of the middle beam plate 9 with screws, with the respective screw holes 19 as the axes. Middle beam plate 9 of this screw holding fitting 20
A hole is provided at the center of the head horizontal plate member 20a parallel to the head horizontal plate member 20a, through which the neck of the fixing screw 21 passes loosely.

Fixing screw 21 with a tapered tip 21a
attaches the head to the head horizontal plate member 2 so as to loosely pass through the hole in the head horizontal plate member 20a and the screw hole 19 in the middle beam plate 9.
It is installed below 0a. A C-shaped hinge 22 is fixed to the neck of the fixing screw 21 in the screw holding fitting 20, and a compression coil spring 23 is mounted between the C-shaped hinge 22 and the head horizontal plate member 20a.

Therefore, the fixing screw 21 is held vertically by the screw holding fitting 20, and is given an upward lifting force by the elasticity of the compression coil spring 23. The fixing position of the C-shaped ring 22 is set so that the screw tip 21a protrudes above the plane formed by the upper surface of the slide plate 10.

To accommodate the housing accommodating device 1 in the cabinet-shaped device 5, the casing accommodating device 1 is placed on the slide plate 10 through the insertion window 8 and pushed into the cabinet-shaped device 5. As a result, the device bottom plate 3 comes into contact with the screw tip 21a and pushes the fixing screw 21 downward.

Then, the housing housing device 1 is further pushed to bring the device side plate into contact with the stopper/sliding plate 11. Next, the device front plate 2
Shift the stopper plate 6A sideways so that it comes into contact with the stopper plate 6A.

When the housing housing device 1 is positioned in this manner, the screw hole 4 of the device bottom plate 3 is positioned opposite to the fixing screw 21.

Therefore, due to the elasticity of the compression coil spring 23, the fixing screw 21
is lifted, and the screw tip 21a is automatically inserted into the screw hole 4.
Insert it into the bottom edge of.

Therefore, the housing housing device 1 can be fixed to the cabinet-shaped device 5 simply by screwing the fixing screw 21.

Note that, in order to remove the housing accommodating device 1, the fixing screw 21 is loosened, and then the housing accommodating device 1 is pulled out. At this time, by moving the housing housing device 1, the fixing screws 21 come into contact with the back surface of the device bottom plate 3 and automatically sink. Therefore, it is extremely easy to attach and detach the housing housing device 1.

Slide plate 10. Since the stopper/slide plate 11 is made of a material with a small coefficient of friction, the frictional resistance caused by the movement of the housing housing device 1 is small, and the housing housing device 1 can be slid and moved with a weak force. , positioning work is easy.

〔Effect of the invention〕
