Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a unit structure in which electronic parts and the like are mounted,
Particularly, it relates to a unit structure having excellent space efficiency.

[Prior Art] FIG. 3A shows a perspective view of a conventional unit structure.

Reference numeral 10 is a shield block that houses a plurality of high frequency circuits 11 provided inside each room and hermetically shields the high frequency circuits 11. The high frequency circuit 11 is composed of two high frequency circuits 11 and 11 housed in the two shield blocks 10 and 10.
It constitutes one function (unit unit).

The shield block 10 is provided with a plug 12 at the bottom, and this shield block is stored upright in a storage portion 13a of the device 13 as shown in the front view of FIG. 3 (b). The high frequency circuit 11 is a plug-in type that forms a part of the device 13 by being inserted into the connector 14.

Here, the storage unit 13a has a predetermined height, width, and
The length direction is determined, and since the shield block 10 is provided upright, the storage efficiency of the storage portion 13a is excellent. On the other hand, shield block 10
May not be stored in this storage portion 13a unless it is divided into two. In particular, the high-frequency circuit 11 may be divided when it needs to be large in space.

[Problems to be Solved by the Invention] Here, 20 is a substrate provided with elements for supplying power and control information to the high frequency circuit 11 on both sides. This board 20 is finally provided for each of the high frequency circuits 11, 11 to achieve the purpose of integrating the functions of the unit.

It is desirable that this board 20 be connected to a plurality of high-frequency circuits 11 provided at the shortest distance. This is caused by the restriction on the wiring technology that minimizes the exposure and routing of the wiring.

However, due to the board 20, as shown in FIG. 3B, the space occupied by the board 20 in the housing portion 13a is large, and as a result, there is a problem in that the housing efficiency per unit is lowered.

Further, since a plurality of high frequency circuits 11 are provided in the shield block 10 in a distributed manner, the constituent elements are also provided on the substrate 20 in a dispersed manner on the upper portion of the high frequency circuit 11 in which the components are distributed, and the substrate 20 itself Is not efficient to use.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a unit structure that can improve the storage efficiency of a unit when the unit is placed in a predetermined storage space. .

[Means for Solving the Problems] In order to achieve the above object, the unit structure of the present invention is a device
A unit structure in which two shield blocks 10, 10 having a high-frequency circuit accommodated in the accommodating portion 13a of 13 and printed wiring boards 1a, 1b provided between the shield blocks are accommodated in a stacked state. The printed wiring board is arranged so as to be nested between the shield blocks and is electrically and mechanically connected and fixed to one of the shield blocks, and the printed wiring board is The substrates are arranged on the same plane.

[Operation] According to the above configuration, when the unit is faced and stored in the storage portion 13a, the substrates 1a and 1b forming part of the unit are arranged.
Since they are located on the same surface without interfering with each other,
Space efficiency at a can be improved.

[Embodiment] FIG. 1 is a perspective view showing an embodiment of a unit structure according to the present invention.

In this embodiment, the same parts as those in the prior art are designated by the same reference numerals.

A plurality of high-frequency circuits 11 are dispersed in the inside of each of the shield blocks 10, 10 that form one unit with two high-frequency circuits.
The high-frequency circuit 11 is hermetically shielded for each room.

A substrate 1 is provided on each shield block 10 via a spacer 2.
Is provided. Elements for supplying power and control signals to the high frequency circuit 11 are provided on the substrate 1.

The substrate 1 is provided with a plurality of notches 4 corresponding to the arrangement state of the high frequency circuit 11. The substrate 1 is composed of substrates 1a and 1b obtained by dividing a single substrate into a plurality of pieces (two pieces in the embodiment).

The shape of the notch 4 at the time of division is the high frequency circuit 11
Are distributed in the shield block 10, it is desirable to cut and form them so as to be located above the high frequency circuit 11.

The unit structure having the above configuration is housed in the housing portion 13a as shown in the front view of FIG.

As shown in this figure, a shield block that constitutes one unit
By accommodating the substrates 1a and 1b provided on the substrate 10 so as to face each other, the substrates 1a and 1b are aligned in the same plane.

Therefore, the space required for the substrate 1 is about half that of the conventional case, and the storage efficiency of the storage portion 13a can be improved.

In the embodiment described above, the plurality of divided substrates 1a, 1
Although b fits in a nested manner, there is no restriction on the arrangement of the circuit or the like of the other mode corresponding to the above-mentioned high frequency circuit 11, and if it can be placed on the upper side of one shield block and on the lower side of the other shield block. The substrates 1a and 1b may be divided into upper and lower parts, and in addition, they may be divided into two parts in the vertical direction.

[Effect of the Invention] According to the present invention, since the area occupied by the unit can be reduced, the space efficiency in the storage portion can be improved.

And many units can be stored in the storage part of a limited space.
