Description

本発明は、電子回路基板の実装構造に係り、詳しくは２つの電子回路基板の連結や半開放状態での固定が容易にできる電子回路基板の実装構造に関する。   The present invention relates to an electronic circuit board mounting structure, and more particularly to an electronic circuit board mounting structure in which two electronic circuit boards can be easily connected and fixed in a half-open state.

メイン基板とサブ基板等、２つの電子回路基板を積み重ねて電子装置を構成するに当たり、これらの結合方法として、従来、例えばネジと間隔スペーサを用いてメイン基板にサブ基板を結合する方法や、ネジを使わず樹脂で成形した専用の保持部材のみでメイン基板にサブ基板を結合する方法、或いは特許文献１に開示された従来例と同様、ネジと蝶番を用いてサブ基板をメイン基板に結合する方法が広く知られている。
特開平１０−２３９５３０号公報 When two electronic circuit boards, such as a main board and a sub board, are stacked to form an electronic device, conventionally, for example, a method of connecting the sub board to the main board using a screw and a spacer, As in the conventional example disclosed in Patent Document 1, the sub-board is connected to the main board using a screw and a hinge as in the conventional method disclosed in Patent Document 1 using only a dedicated holding member molded from resin without using The method is widely known.
JP-A-10-239530

ところで、このように電子回路基板を積み重ねて構成される電子装置では、組み立て時に一方の電子回路基板を半開放状態にして基板間の配線を行い、また、試験調整（回路の微調整等）を行う場合がある。
しかし、上述した何れの電子回路基板の結合方法にあっては、基板間の配線や調整時にサブ基板をメイン基板に対して一時的に半開放状態に維持することができない（サブ基板を所定の位置に固定できない）ため、サブ基板が不安定となって作業に熟練を要していた。 By the way, in an electronic device configured by stacking electronic circuit boards in this way, wiring between the boards is performed with one electronic circuit board in a semi-open state at the time of assembly, and test adjustment (such as fine adjustment of a circuit) is performed. May do.
However, in any of the above-described electronic circuit board coupling methods, the sub-board cannot be temporarily kept in a semi-open state with respect to the main board during wiring or adjustment between the boards (the sub-board cannot be set in a predetermined manner). Therefore, the sub-board becomes unstable and requires skill.

このため、ネジと間隔スペーサを用いた従来構造では、基板間の配線や調整時にサブ基板とメイン基板をバラしているのが実情で、この作業は手間が掛かり、また、例えば調整に当たり配線された基板同士をバラしてしまうと、予期せぬトラブルが発生してしまうおそれがある。
一方、専用の樹脂製の保持部材を用いた従来構造にあっては、保持部材の構造上、その取り外しに手間が掛かり、分解作業に熟練を要しているのが実情であり、また、このように保持部材を外してメイン基板とサブ基板をバラすことで、同様に予期せぬトラブル発生のおそれがある。 For this reason, in the conventional structure using screws and spacing spacers, the situation is that the sub board and the main board are separated during wiring and adjustment between the boards, and this work is troublesome, and for example, wiring is performed for adjustment. If the substrates are separated from each other, an unexpected trouble may occur.
On the other hand, in the conventional structure using a dedicated resin holding member, it takes a lot of time to remove it due to the structure of the holding member. If the holding member is removed as described above and the main board and the sub board are separated, an unexpected trouble may occur as well.

また、ネジと蝶番を用いてサブ基板とメイン基板を保持した従来構造にあっては、サブ基板を一時的に半開放状態に維持することができないため、サブ基板を見開き状態に展開して作業を行っているのが実情であるが、サブ基板を見開き状態に展開するために広い作業スペースを必要としていた。
しかも、このようにサブ基板を見開き状態に展開したり、既述したようにメイン基板からサブ基板をバラした場合、サブ基板上の実装部品を他の物にぶつけてしまうおそれもある。 Also, in the conventional structure where the sub-board and main board are held using screws and hinges, the sub-board cannot be temporarily kept in a semi-open state, so that the sub-board is spread out to work. However, a large work space is required to spread the sub-board in a spread state.
In addition, when the sub-board is spread in a spread state as described above, or the sub-board is separated from the main board as described above, the mounted component on the sub-board may collide with another object.

更にまた、ネジと蝶番を用いた結合方法の場合、サブ基板を半開放状態に維持することができないため、作業中のサブ基板を回転防止用治具等を使って支えることもあるが、斯かる治具を用いることなく、サブ基板を一時的に半開放状態に維持，固定することができるメイン基板とサブ基板の結合方法が望まれていた。
本発明は斯かる実情に鑑み案出されたもので、２つの電子回路基板の連結や半開放状態での固定が容易にできる電子回路基板の実装構造を提供することを目的とする。 Furthermore, in the case of a coupling method using screws and hinges, the sub-board cannot be maintained in a half-open state, and therefore the sub-board in operation may be supported using a rotation prevention jig or the like. There has been a demand for a method of connecting a main board and a sub board that can temporarily maintain and fix the sub board in a semi-open state without using a jig.

The tongue piece 45 is not caught on the peripheral edge of the slit 31 during the rotation operation on the one side.

本実施形態はこのように構成されており、次に、上記連結部材１，７，９を用いたメイン基板１１とサブ基板３の実装方法を図４乃至図６に基づいて説明する。
先ず、連結部材１のスリット２９に対応して、連結部材７，９をメイン基板１１の一端側表面にネジ止めする。このとき、連結部材１の脚部２１側に舌片４５を配置する。
そして、図４に示すように、連結部材７，９側のスリット３９と連結部材１側のスリット２９を一致させて、連結部材１を上方からスリット３９内に挿入する。このとき、図４の実線で示すように連結部材１を真下までスライドさせて、スリット２９，３１間の連結部材１を連結部材７，９のスリット４１に係合させると、連結部材１が半開放状態、即ち、メイン基板１１に対し９０°の角度でメイン基板１１上に位置決め保持される。 The present embodiment is configured as described above. Next, a mounting method of the main board 11 and the sub board 3 using the connecting members 1, 7 and 9 will be described with reference to FIGS. 4 to 6.
First, the connecting members 7 and 9 are screwed to the one end side surface of the main board 11 corresponding to the slits 29 of the connecting member 1. At this time, the tongue piece 45 is disposed on the leg 21 side of the connecting member 1.
Then, as shown in FIG. 4, the connecting member 1 is inserted into the slit 39 from above, with the slit 39 on the connecting member 7, 9 side and the slit 29 on the connecting member 1 side being matched. At this time, as shown by the solid line in FIG. 4, when the connecting member 1 is slid to the bottom and the connecting member 1 between the slits 29 and 31 is engaged with the slit 41 of the connecting members 7 and 9, the connecting member 1 is half It is positioned and held on the main board 11 in an open state, that is, at an angle of 90 ° with respect to the main board 11.

一方、図４の破線及び図５の実線で示すように連結部材１を真下までスライドさせずに、スリット２９，３１間を回動操作孔３３に配置させた状態で、連結部材１を図５の矢印Ａ方向へ９０°回動させて、図６に示すように連結部材の取付フランジ２３をメイン基板１１に当接させた後、連結部材１を破線の位置から実線で示すように矢印Ｂ方向へスライドさせて、スリット２９，３１間の連結部材１を連結部材７のスリット４３に係合させると、連結部材１が連結部材７（メイン基板１１）に固定される。   On the other hand, as shown by the broken line in FIG. 4 and the solid line in FIG. 5, the connecting member 1 is placed in the rotation operation hole 33 between the slits 29 and 31 without sliding the connecting member 1 to the position directly below. After rotating 90 ° in the direction of arrow A and bringing the attachment flange 23 of the connecting member into contact with the main board 11 as shown in FIG. 6, the connecting member 1 is moved from the position of the broken line to the arrow B as shown by the solid line. When the connecting member 1 between the slits 29 and 31 is engaged with the slit 43 of the connecting member 7 by sliding in the direction, the connecting member 1 is fixed to the connecting member 7 (main substrate 11).

そして、このとき、取付フランジ２３とメイン基板１１に設けたネジ孔が一致するように構成されており、両ネジ孔にネジ２５を締め付けて連結部材１が連結部材７（メイン基板１１）に完全に固定される。
このように連結部材１をメイン基板１１に完全に固定した後、連結部材１上にサブ基板３をネジ止めすればよく、また、メイン基板１１への組付けに当たり、予め連結部材１上にサブ基板３をネジ止めしておいてもよい。 At this time, the mounting flange 23 and the screw holes provided in the main board 11 are configured to coincide with each other, and the connecting member 1 is completely connected to the connecting member 7 (main board 11) by tightening the screws 25 in both screw holes. Fixed to.
After the connecting member 1 is completely fixed to the main board 11 in this way, the sub board 3 may be screwed onto the connecting member 1, and the sub board 3 is previously placed on the connecting member 1 for assembly to the main board 11. The substrate 3 may be screwed.

そして、このようにサブ基板３をメイン基板１１に組み付けた後、例えばサブ基板３を半開放状態にして配線を行い、また、試験調整を行う際には、上述した手順と逆の操作を行うこととなる。
即ち、先ず、連結部材１がメイン基板１１に完全に固定された図６の状態で、ネジ２５を外し、連結部材１を矢印Ｃ方向へスライドさせてスリット４３との係合状態を解除する。 Then, after the sub-board 3 is assembled to the main board 11 in this way, for example, the wiring is performed with the sub-board 3 being in a half-open state, and when the test adjustment is performed, an operation reverse to the above-described procedure is performed. It will be.
That is, first, in the state shown in FIG. 6 in which the connecting member 1 is completely fixed to the main board 11, the screw 25 is removed, and the connecting member 1 is slid in the direction of arrow C to release the engaged state with the slit 43.

この後、連結部材１のスリット２９，３１間を回動操作孔３３に配置させた状態で、図５の如く連結部材５を矢印Ｄ方向へ９０°回転させて、図４の実線で示すように連結部材１を真下までスライドさせれば、連結部材１がスリット４１に係合して連結部材１が半開放状態で位置決め保持される。そして、スリット３９に沿って連結部材１を上方へスライドさせれば、メイン基板１１からサブ基板３を完全に取り外すことができる。   Thereafter, the connecting member 5 is rotated by 90 ° in the direction of arrow D as shown in FIG. 5 with the slits 29 and 31 of the connecting member 1 disposed in the rotation operation hole 33, as shown by the solid line in FIG. When the connecting member 1 is slid to just below, the connecting member 1 engages with the slit 41, and the connecting member 1 is positioned and held in a half-open state. Then, if the connecting member 1 is slid upward along the slit 39, the sub-board 3 can be completely removed from the main board 11.
