本発明は、筐体等に複数の印刷配線板を階層状に装着す
る実装構造に関する。The present invention relates to a mounting structure in which a plurality of printed wiring boards are mounted on a housing or the like in a hierarchical manner.
電子機器においては、複数の印刷配線板を箱形の筐体に
階層状に実装することがしばしばある。In electronic devices, a plurality of printed wiring boards are often mounted in a box-shaped housing in a hierarchical manner.
この際、印刷配線板を収容する筐体を、小形にすること
ができる実装構造が望ましい。At this time, it is desirable to have a mounting structure that allows the casing that accommodates the printed wiring board to be made smaller.
第3図は従来の実装構造を示す側断面図、第4図は従来
例の要部斜視図である。FIG. 3 is a side sectional view showing a conventional mounting structure, and FIG. 4 is a perspective view of essential parts of the conventional example.

にはそれぞれ搭載部品2を実装しであるが、その搭載部
品の最高の実装高は、印刷配線板により異なる。1-1.1-2. L3 is a printed wiring board mounted in a hierarchical manner within the housing 5. Surface of printed wiring board (lower surface in the figure)
A mounted component 2 is mounted on each of the boards, and the maximum mounting height of the mounted component differs depending on the printed wiring board.
例えば印刷配線板1−1に実装した搭載部品2の実装高
さは、他の印刷配線板1−2.1−3に実装した搭載部
品2の実装高さよりもはるかに高い。For example, the mounting height of the mounted component 2 mounted on the printed wiring board 1-1 is much higher than the mounting height of the mounted component 2 mounted on the other printed wiring boards 1-2, 1-3.
また、これらの印刷配線板1−1 、1−2.1−3の
4隅には、それぞれ間隔管10のねじ部12を遊貫する
円孔3を設けである。Furthermore, circular holes 3 are provided at the four corners of these printed wiring boards 1-1, 1-2, and 1-3, respectively, so that the threaded portions 12 of the spacer tubes 10 pass through them.
一方、筺体5の底板6にも、印刷配線板の円孔3に対向
した位置に、間隔管10が螺着するねじ孔8を設けであ

上述のような間隔管10を用いて、印刷配線板を実装す
るには、まず、ねじ孔8のそれぞれに間隔管10のねじ
部12を螺着して、間隔管10を底板6に植立させる。To mount a printed wiring board using the spacer tubes 10 as described above, first, the threaded portions 12 of the spacer tubes 10 are screwed into each of the screw holes 8, and the spacer tubes 10 are planted on the bottom plate 6. let
植立した間隔管10の上面に搭載部品2を下側にして印

を嵌挿し、下方の間隔管10のねし孔11に螺着して、
2つの間隔管10で、印刷配線板1−1を挟着し固定す
る。Place the printed wiring board 1-1 on the top surface of the spacer tube 10 that has been planted, with the mounting component 2 facing downward, insert the threaded part of another spacer tube into the circular hole 3, and tighten the thread of the lower spacer tube 10. screw into hole 11,
The printed wiring board 1-1 is sandwiched and fixed between the two spacer tubes 10.
印刷配線板1−1上に固着した上段の間隔管10の上面

印刷配線板1−2を固定する。さらに、同様にして印刷
配線板1−2の上方に印刷配線板1−3を固定する。し
たがって、最上層の印刷配線板l−3の上部にも間隔管
10が固着されている。Another printed wiring board 1-2 is placed on the upper surface of the upper spacer tube 10 fixed on the printed wiring board 1-1, and the printed wiring board 1-2 is fixed in the same manner as described above. Furthermore, printed wiring board 1-3 is similarly fixed above printed wiring board 1-2. Therefore, the spacer tube 10 is also fixed to the top of the uppermost printed wiring board l-3.
上述のように構成されているので、筐体5の底板6と最
下層の印刷配線板1−1の間隔、及び印刷配線板相互間
は、間隔管10の高さに等しい一定の間隔で、階層状に
印刷配線板が実装される。Since the structure is as described above, the distance between the bottom plate 6 of the housing 5 and the lowermost printed wiring board 1-1, and the distance between the printed wiring boards is a constant distance equal to the height of the spacer tube 10. Printed wiring boards are mounted in a layered manner.
なお、最上層の印刷配線板1−3と蓋7の間隔は、間隔
管10の高さよりもわずかに大きい。Note that the distance between the top layer printed wiring board 1 - 3 and the lid 7 is slightly larger than the height of the spacer tube 10 .
一方近年は、相互の間隔をできるだけ小さい階層状に、
印刷配線板を実装して、装置の小形化を推進することが
要求されている。On the other hand, in recent years, the space between layers has been reduced as much as possible,

恐れがあった。Further, as shown in FIG. 4, the end surface of a spacer tube 10 made of a metal material comes into contact with the periphery of the circular hole 3 of the printed wiring board. Therefore, a conductive pattern cannot be formed in an area projected onto a circular shape concentric with the circular hole 3, which has a diameter larger than the outer diameter of the spacer tube 10, and there is a risk that the pattern forming area will be reduced.

ることが容易である。At this time, since the length of the square hole 30-2 provided in the printed wiring board 1-2 is smaller than the length of the square hole provided in the other printed wiring boards, a diamond shape to be inserted into the square hole 30-2 is formed. Since the amount of fitting at the apex portion of the spacing plate 20 is small, the distance between the printed wiring board 1-1 and the printed wiring board 1-2 is equal to the distance between the bottom plate 6 and the printed wiring board Ll, and the distance between the printed wiring board 1-2 and the printed wiring board 1-2. It is easy to make the distance larger than the distance from the printed wiring board 1-3. That is, printed wiring board 1
It is easy to adjust the distance to a desired large distance so that the head of the mounted component 2A mounted on the board 1-2 does not hit the lower printed wiring board 1-1.
なお、印刷配線板に長さが一定の角孔を穿設しておけば
、角孔の長さは、やすり等を用いることにより、手で容
易に太き(することができる。Note that if a square hole of a constant length is drilled in the printed wiring board, the length of the square hole can be easily increased by hand using a file or the like.

の面積にほぼ等しくて小さい。Furthermore, even if the fixing pin 25 is made of metal as shown in FIG. The area that cannot be formed is small and almost equal to the area of the square hole.
即ち印刷配線板のパターン形成領域が広い。That is, the pattern formation area of the printed wiring board is wide.
なお、印刷配線板を実装するには、上述と異なり、予め

形間隔板20を底板6に固着しても良い。Note that in order to mount the printed wiring boards, unlike the above, the printed wiring boards 1-1.1-2.1-3 are first mounted in a hierarchical manner using the diamond-shaped spacing plates 20 and fixing pins 25 outside the housing 5. Assemble to,
The final assembled state may be inserted into the housing 5 and the lower diamond-shaped spacing plate 20 may be fixed to the bottom plate 6.
さらにまた、図示例とは異なり、それぞれの印刷配線板

り、調整できるものである。Furthermore, the spacing between printed wiring boards is not only adjusted by the length of the square holes, but also by making the apex of the upper and lower diamond-shaped spacing plates deeper (by inserting them into the square holes). This can be adjusted depending on what you want to do.
したがって、角孔の長さが一定であっても、印刷配線板

This has excellent practical effects, such as a compact apparatus in which printed wiring boards are housed in a hierarchical manner and a wide pattern formation area on the printed wiring boards.
