Description

本発明は、各種電子機器の筺体内に収納されるプリント基板の取付構造に関するものである。   The present invention relates to a mounting structure for a printed circuit board housed in a housing of various electronic devices.

従来のプリント基板の取付構造としては、断面Ｌ字状に形成された筺体の底板にスタッドを設け、背面板にガイド穴を設け、プリント基板には前記スタッドに対応するねじ挿通孔を設けるとともに、一端縁に前記ガイド穴に挿入される突起を設けたものがある。このような構造においては、プリント基板の突起を筺体のガイド穴に挿入し、プリント基板のねじ挿通孔に挿通させたねじをスタッドに螺合させることより、プリント基板を筺体に取り付けている（例えば、特許文献１参照）。
特開２００５−２８６１９９号公報（段落「００３８」および「００４０」、図１） As a conventional printed circuit board mounting structure, a stud is provided on the bottom plate of the housing formed in an L-shaped cross section, a guide hole is provided on the back plate, a screw insertion hole corresponding to the stud is provided on the printed circuit board, There is one provided with a protrusion inserted into the guide hole at one end edge. In such a structure, the printed circuit board is attached to the housing by inserting the protrusion of the printed circuit board into the guide hole of the housing and screwing the screw inserted through the screw insertion hole of the printed circuit board into the stud (for example, , See Patent Document 1).
JP 2005-286199 A (paragraphs “0038” and “0040”, FIG. 1)

上述した従来のプリント基板の取付構造においては、プリント基板の一端側に設けた突起をガイド穴に挿入するだけの構造であるため、プリント基板に反りが発生していると、プリント基板の他端側がスタッドから浮き上がることがあり、プリント基板のスタッドへのねじ締め作業に際し、プリント基板を押圧しながらねじ締めを行わなければならないことになり作業が煩雑になるという問題があった。また、反りによる弾発力により完全にねじ締めされないにもかかわらずねじ締めを完結してしまい、実際にはねじが緩んだ状態でねじ締めされているおそれがあるため、スタッドの数を必要以上に増やすことによりスタッドへのねじ締め作業がより煩雑になっていた。   In the conventional printed circuit board mounting structure described above, since the protrusion provided on one end side of the printed circuit board is merely inserted into the guide hole, if the printed circuit board is warped, the other end of the printed circuit board There is a problem that the side is lifted from the stud, and the screw tightening operation to the stud of the printed circuit board has to be performed while pressing the printed circuit board and the work becomes complicated. Also, due to the elastic force caused by warpage, the screw tightening may be completed despite the fact that the screw is not completely tightened, and the screw may actually be tightened with the screw loosened. By increasing the number of screws, the screw tightening work on the stud becomes more complicated.

本発明は上記した従来の問題に鑑みなされたものであり、その目的とするところは、プリント基板の取付作業の作業性を向上させるところにある。   The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to improve the workability of the printed board mounting operation.

As shown in FIG. 6, the distance l1 between the base end 7c of the first locking portion 7b of the first engagement piece 7 and the back plate 13 is equal to the end of the printed circuit board 18 in the direction of arrow C and the mounted component. It is formed longer than the distance L1 from the end of 19A in the arrow D direction. The distance l2 between the first locking portion 7b and the rear plate 13 of the first engagement piece 7 is formed shorter than the arrow C-D direction length L2 of the printed circuit board 18.

アッパーケース３は、図５に示すように、上板２０とこの上板２０の周縁から一体に立設された囲い壁２１とによって形成されており、囲い壁２１の前板２１Ａの内面には、第１の係合片７の係合凹部７ａに係合する被係合片２２が一体に突設されている。上板２０の矢印Ｄ側の端部には、ロアーケース２のスタッド１５に対応して有底円筒状に形成された凹部２３が設けられており、この凹部２３の押圧部としての底部２３ａには、ねじ１６が挿通されるねじ挿通孔２３ｂが形成されている。上板２０の矢印Ｄ側の端縁２０ａは、ロアーケース２の開口１２の上方を覆っており、後板６Ｂのガイド壁６ａに係入される背面板１３の抜けを規制する。   As shown in FIG. 5, the upper case 3 is formed by an upper plate 20 and a surrounding wall 21 erected integrally from the peripheral edge of the upper plate 20, and on the inner surface of the front plate 21 </ b> A of the surrounding wall 21. The engaged piece 22 that engages with the engaging recess 7a of the first engaging piece 7 is integrally projected. A concave portion 23 formed in a bottomed cylindrical shape corresponding to the stud 15 of the lower case 2 is provided at an end portion on the arrow D side of the upper plate 20, and a bottom portion 23 a as a pressing portion of the concave portion 23 is provided. A screw insertion hole 23b through which the screw 16 is inserted is formed. An edge 20a on the arrow D side of the upper plate 20 covers the upper portion of the opening 12 of the lower case 2, and restricts the back plate 13 inserted into the guide wall 6a of the rear plate 6B from coming off.

次に、このような構成のプリント基板の取付構造におけるプリント基板の取付方法について説明する。予め、アッパーケース３をロアーケース２から取り外し、図７に示すようにロアーケース２の上方を開放させ、背面板１３をロアーケース２の後板６Ｂのガイド壁６ａに係入させておく。この状態で、プリント基板１８をロアーケース２の斜め上方から矢印Ｅ方向に移動させることにより、ロアーケース２内に差し入れ、先端部を第１の係止部７ｂの下方に挿入する。   Next, a method for mounting a printed board in the printed board mounting structure having such a configuration will be described. The upper case 3 is removed from the lower case 2 in advance, the upper portion of the lower case 2 is opened as shown in FIG. 7, and the back plate 13 is engaged with the guide wall 6a of the rear plate 6B of the lower case 2. In this state, the printed circuit board 18 is moved in the direction of arrow E from obliquely above the lower case 2 to be inserted into the lower case 2 and the tip is inserted below the first locking portion 7b.

プリント基板１８の矢印Ｃ方向の端部が第１の係止部７ｂの基端７ｃに当接するまで、プリント基板１８を矢印Ｅ方向に移動させた後、プリント基板１８を矢印Ｆ方向に回動させる。このとき、第１の係止部７ｂの基端７ｃと背面板１３との間隔ｌ１が、プリント基板１８の矢印Ｃ方向の端部と、実装部品１９Ａの矢印Ｄ方向の端部との間隔Ｌ１よりも長く形成されているため、実装部品１９Ａが背面板１３に当れることなく、プリント基板１８をロアーケース２内に挿入することができる。   The printed circuit board 18 is moved in the direction of arrow E until the end of the printed circuit board 18 in the direction of arrow C contacts the base end 7c of the first locking portion 7b, and then the printed circuit board 18 is rotated in the direction of arrow F. Let At this time, the distance l1 between the base end 7c of the first locking portion 7b and the back plate 13 is the distance L1 between the end in the arrow C direction of the printed circuit board 18 and the end in the arrow D direction of the mounting component 19A. Therefore, the printed circuit board 18 can be inserted into the lower case 2 without the mounting component 19 </ b> A hitting the back plate 13.

ロアーケース２内に挿入されたプリント基板１８は載置片１１の載置部１１ａ上に載置されるとともに、ロアーケース２の両側部６Ｃ，６Ｄの載置片１１の規制部１１ｂ，１１ｂがプリント基板１８の矢印Ａ−Ｂ方向の端部に係合し、プリント基板１８の幅方向（矢印Ａ−Ｂ方向）への移動が規制される。載置片１１の載置部１１ａ上に載置されたプリント基板１８は、矢印Ｃ方向の端部の上面がロアーケース２の矢印Ａ−Ｂ方向の両端部に設けた第１の係止部７ｂ，７ｂに係止されるため、仮にプリント基板１８に矢印Ａ−Ｂ方向における反りが発生していたとしても、これら第１の係止部７ｂ，７ｂによって矯正される。このとき、第１の係止部７ｂ，７ｂ間の略中央部に設けられた第２の係止片１０にプリント基板１８の矢印Ａ−Ｂ方向の中央部の上面が係止されるため、プリント基板１８の矢印Ａ−Ｂ方向全体における反りが確実に矯正される。   The printed circuit board 18 inserted into the lower case 2 is placed on the placement portion 11a of the placement piece 11, and the restricting portions 11b and 11b of the placement pieces 11 on both side portions 6C and 6D of the lower case 2 are provided. The end of the printed circuit board 18 in the direction of arrow AB is engaged, and movement of the printed circuit board 18 in the width direction (direction of arrow AB) is restricted. The printed circuit board 18 placed on the placement portion 11a of the placement piece 11 has a first locking portion in which the upper surface of the end portion in the arrow C direction is provided at both end portions in the arrow AB direction of the lower case 2. Since they are locked to 7b and 7b, even if the printed circuit board 18 is warped in the arrow AB direction, it is corrected by these first locking portions 7b and 7b. At this time, since the upper surface of the central portion in the arrow AB direction of the printed circuit board 18 is locked to the second locking piece 10 provided in the substantially central portion between the first locking portions 7b, 7b, Warpage of the entire printed circuit board 18 in the direction of arrow AB is reliably corrected.

次いで、プリント基板１８を矢印Ｄ方向にわずかに移動させ、プリント基板１８の矢印Ｄ方向の端部を背面板１３に当接させる。このとき、第１の係止部７ｂと背面板１３との間隔ｌ２が、プリント基板１８の矢印Ｃ−Ｄ方向の長さＬ２よりも短く形成されているから、プリント基板１８の矢印Ｃ方向の端部が、図６に示すように第１の係止部７ｂに係止された状態が保持される。また、プリント基板１８の矢印Ｄ方向の端部に実装された５個の実装部品１９Ａないし１９Ｅが、図２に示すように背面板１３の５個の窓１３Ａないし１３Ｅのそれぞれに臨む。また、プリント基板１８の矢印Ｄ方向の端部を背面板１３に当接させることにより、上述したように載置片１１，１１の規制部１１ｂ，１１ｂによってプリント基板１８の幅方向（矢印Ａ−Ｂ方向）への移動が規制されているため、プリント基板１８のねじ挿通孔１８ａがロアーケース２のスタッド１５に対向する。   Next, the printed board 18 is slightly moved in the direction of arrow D, and the end of the printed board 18 in the direction of arrow D is brought into contact with the back plate 13. At this time, the interval 12 between the first locking portion 7b and the back plate 13 is formed to be shorter than the length L2 of the printed circuit board 18 in the direction of arrow CD, so As shown in FIG. 6, the state in which the end portion is locked to the first locking portion 7b is maintained. Further, the five mounting components 19A to 19E mounted on the end of the printed circuit board 18 in the direction of arrow D face each of the five windows 13A to 13E of the back plate 13 as shown in FIG. Further, by bringing the end portion of the printed circuit board 18 in the direction of arrow D into contact with the back plate 13, as described above, the restricting portions 11b and 11b of the mounting pieces 11 and 11 make the width direction of the printed circuit board 18 (arrow A− Since the movement in the (B direction) is restricted, the screw insertion hole 18 a of the printed circuit board 18 faces the stud 15 of the lower case 2.

次いで、アッパーケース３の被係合片２２を、図５に示すようにロアーケース２の第１の係合片７の係合凹部７ａに係合させ、この第１の係合片７を回動中心としてアッパーケース３を矢印Ｆ方向に回動させることにより、このアッパーケース３によってロアーケース２の開口を閉塞する。 Then, the engaged piece 22 of the upper case 3, is engaged with the engaging recess 7a of the first engaging piece 7 of the lower case 2 as shown in FIG. 5, the first engagement piece 7 times By rotating the upper case 3 in the direction of arrow F as the moving center, the upper case 3 closes the opening of the lower case 2.

この状態で、凹部２３のねじ挿通孔２３ｂ、プリント基板１８のねじ挿通孔１８および背面板１３のねじ挿通孔１４ａに挿通させたねじ１６をスタッド１５に螺合させることにより、アッパーケース３がロアーケース２に取り付けられる。同時に、プリント基板１８および背面板１３が、アッパーケース３と共にスタッド１５に共締めされる。このねじ締め作業時に、予めアッパーケース３をロアーケース２側に押圧することにより、アッパーケース３の凹部２３の底部２３ａがプリント基板１８の矢印Ｄ方向の端部を押圧するため、仮にプリント基板１８に矢印Ａ−Ｂ方向における反りが発生していたとしても、アッパーケース３の凹部２３の底部２３ａによって矯正される。また、上述したようにプリント基板１８は矢印Ｃ方向の端部が、第１の係止部７ｂおよび第２の係止片１０によって係止されているため、仮にプリント基板１８に矢印Ｃ−Ｄ方向における反りが発生していたとしても、第１の係止部７ｂおよび第２の係止片１０およびアッパーケース３の凹部２３の底部２３ａによって矯正される。   In this state, the screw 16 inserted through the screw insertion hole 23b of the recess 23, the screw insertion hole 18 of the printed circuit board 18 and the screw insertion hole 14a of the back plate 13 is screwed into the stud 15, so that the upper case 3 is lowered. It is attached to case 2. At the same time, the printed circuit board 18 and the back plate 13 are fastened together with the stud 15 together with the upper case 3. During the screw tightening operation, the upper case 3 is pressed in advance toward the lower case 2 so that the bottom 23a of the recess 23 of the upper case 3 presses the end of the printed circuit board 18 in the arrow D direction. Even if the warp in the direction of the arrow AB occurs, the bottom 23a of the recess 23 of the upper case 3 corrects it. Further, as described above, the printed circuit board 18 is locked at the end in the direction of the arrow C by the first locking portion 7b and the second locking piece 10, so that the printed circuit board 18 has an arrow C-D. Even if warping occurs in the direction, it is corrected by the first locking portion 7b, the second locking piece 10, and the bottom 23a of the recess 23 of the upper case 3.

したがって、プリント基板１８の反りが矯正された状態でねじ締め作業を行うことができるため、取付作業の作業性が向上する。また、プリント基板１８の反りが矯正されることにより、反りによってプリント基板１８がスタッド１５から浮き上がった状態となるようなことがない。このため、プリント基板１８が反りによってねじが緩んだ状態でねじ締めされるおそれがないから、従来と比較してスタッド１５の数を減らすことができるので取付けに要する時間を短縮することができる。また、プリント基板１８をアッパーケース３と共締めすることにより取付時間を短縮することができる。また、このねじ締め作業に当たっては、上述したようにプリント基板１８のねじ挿通孔１８ａがロアーケース２のスタッド１５に対応しているため、ねじ締め作業が容易になり作業性が向上する。   Therefore, since the screw tightening operation can be performed in a state where the warpage of the printed circuit board 18 is corrected, the workability of the mounting operation is improved. Further, since the warpage of the printed circuit board 18 is corrected, the printed circuit board 18 is not lifted from the stud 15 due to the warpage. For this reason, since there is no possibility that the printed board 18 is screwed in a state where the screw is loosened due to warping, the number of studs 15 can be reduced as compared with the conventional case, so that the time required for mounting can be shortened. Further, the fastening time can be shortened by fastening the printed circuit board 18 together with the upper case 3. Further, in this screw tightening operation, since the screw insertion hole 18a of the printed circuit board 18 corresponds to the stud 15 of the lower case 2 as described above, the screw tightening operation is facilitated and workability is improved.

ここで、仕様の変更によって背面板１３の窓１３Ａないし１３Ｅに臨む実装部品１９Ａないし１９Ｅの位置または形状あるいは種類に変更があったとしても、背面板１３のみを交換するだけで対応できるため使い勝手が向上する。   Here, even if there is a change in the position, shape, or type of the mounting parts 19A to 19E facing the windows 13A to 13E of the back plate 13 due to a change in the specification, it is possible to cope with it by simply replacing the back plate 13, and thus the usability is improved. improves.

なお、本実施の形態においては、ロアーケース２の後板６Ｂに開口１２を設け、この開口１２を覆う背面板１３を設けるようにしたが、仕様に変更がない場合は開口１２を設けることなく、背面板１３をロアーケース２に一体に形成するようにしてもよい。   In this embodiment, the rear plate 6B of the lower case 2 is provided with the opening 12, and the back plate 13 covering the opening 12 is provided. However, if the specification is not changed, the opening 12 is not provided. The back plate 13 may be formed integrally with the lower case 2.
