However, it is necessary to provide a prohibited area where electronic components cannot be mounted around the through hole 52 formed in the printed circuit board 51.
An area for inserting the tool and rotating the nut 55 is also necessary. For this reason, there was a problem that the area efficiency which can mount the electronic component of the printed circuit board 1 fell.

以下に図３以下を参照しつつ、本発明の実施形態を説明する。
図３、図４に示すように、本発明のプリント基板ユニットは、複数枚のプリント基板１を複数の支柱２を介して積層したものである。この実施形態では、各プリント基板１は同一サイズの長方形状の樹脂板である。
Hereinafter, embodiments of the present invention will be described with reference to FIG.
As shown in FIGS. 3 and 4, the printed circuit board unit of the present invention is formed by laminating a plurality of printed circuit boards 1 through a plurality of support columns 2. In this embodiment, each printed circuit board 1 is a rectangular resin plate having the same size.
プリント基板１の端部には、溝状の凹部３、４が複数形成されている。本実施形態では、凹部３は長方形のプリント基板１の一つの長辺の両側の角部に、辺５に対して斜め方向に形成されている。その幅は支柱２の厚さとほぼ等しくなっている。また凹部４が長方形のプリント基板１の反対側の辺６の中央位置に、辺６に対して直角に形成されている。その深さと幅は凹部３と同様である。各プリント基板１には従来と同様、ＩＣ、コンデンサ、抵抗、スイッチ等の様々な電子部品７が実装されている。 A plurality of groove-shaped recesses 3 and 4 are formed at the end of the printed circuit board 1. In the present embodiment, the concave portion 3 is formed in a diagonal direction with respect to the side 5 at corners on both sides of one long side of the rectangular printed board 1. The width is substantially equal to the thickness of the support 2. A recess 4 is formed at a central position of the side 6 on the opposite side of the rectangular printed circuit board 1 and perpendicular to the side 6. Its depth and width are the same as those of the recess 3. Each printed circuit board 1 is mounted with various electronic components 7 such as an IC, a capacitor, a resistor, and a switch as in the conventional case.
支柱２は図４に示すようにこれらの凹部３、４に嵌め込まれるものであり、平板状である。支柱２の片面には複数位置に切欠き８、９が形成されている。切欠き８、９の間隔はプリント基板ユニットにおけるプリント基板１の間隔に等しい。切欠き８、９の深さはプリント基板１の凹部３、４と等しく、その幅はプリント基板１の厚さとほぼ等しくなっている。 As shown in FIG. 4, the support column 2 is fitted into the recesses 3 and 4 and has a flat plate shape. Notches 8 and 9 are formed at a plurality of positions on one side of the support column 2. The interval between the notches 8 and 9 is equal to the interval between the printed circuit boards 1 in the printed circuit board unit. The depths of the notches 8 and 9 are equal to the recesses 3 and 4 of the printed circuit board 1, and the width is substantially equal to the thickness of the printed circuit board 1.
図４に示すように、各支柱２の切欠き８、９を各プリント基板１の溝状の凹部３、４に噛み合せることにより、支柱２とプリント基板１は固定される。本実施形態では支柱２の幅を（切欠き８、９の深さ）＋（凹部３、４の深さ）と等しくしたので、支柱２の外側端部がプリント基板１の端部と一致する。 As shown in FIG. 4, the support 2 and the printed circuit board 1 are fixed by engaging the notches 8 and 9 of each support 2 with the groove-shaped recesses 3 and 4 of each printed circuit board 1. In this embodiment, the width of the support column 2 is made equal to (depth of the notches 8 and 9) + (depth of the recesses 3 and 4), so that the outer end of the support column 2 coincides with the end of the printed circuit board 1. .
このため、図５に示すようにプリント基板ユニットをケース１０に収納したとき、プリント基板１の辺と支柱２の外側端部の双方をケース内壁に当接させることができるので、がたつきを抑えることができる。また、ケース１０に収納する場合、プリント基板１をケース内壁まで拡大して成形できるので実装面積が増加する。 For this reason, as shown in FIG. 5, when the printed circuit board unit is stored in the case 10, both sides of the printed circuit board 1 and the outer end of the support column 2 can be brought into contact with the inner wall of the case. Can be suppressed. Moreover, when storing in case 10, since the printed circuit board 1 can be expanded and shape | molded to a case inner wall, a mounting area increases.
なお、支柱２をプリント基板１に差し込んだときに、支柱２の外側端部がプリント基板１の辺から少し飛び出るような構造であっても良い。この場合には、プリント基板ユニットをケース１０に収納したとき、ケース内壁は支柱２の外側端部に当接する。このような構造とすれば、ケース内壁とプリント基板１との間に空間ができ、その空間を通って電子部品７から発生する熱を外部に放熱することができる利点がある。 In addition, when the support | pillar 2 is inserted in the printed circuit board 1, the structure where the outer side edge part of the support | pillar 2 protrudes a little from the edge | side of the printed circuit board 1 may be sufficient. In this case, when the printed circuit board unit is stored in the case 10, the inner wall of the case comes into contact with the outer end of the column 2. With such a structure, there is an advantage that a space is formed between the inner wall of the case and the printed board 1, and heat generated from the electronic component 7 can be radiated to the outside through the space.
このように、本発明では各支柱２の切欠き８、９を各プリント基板１の溝状の凹部３、４に噛み合せるだけでプリント基板ユニットを構成することができるので、組立作業性に優れる。またプリント基板１上の薄い支柱２が差し込まれるスペースを電子部品を実装できない禁止領域としておけばよいので、プリント基板１の部品実装可能な面積効率を高めることができる。特に２つの角部については、角部の禁止領域を有効に利用することで、広く実装面積を確保することができる。さらに、凹部３を辺５に対して斜め方向に形成することで、凹部３を辺５に対して直角に形成した場合よりも、プリント基板１の辺５から凹部３の先端までの距離を短くすることができる。このため部品実装可能な面積効率をより高めることができる。尚、凹部３をプリント基板１の角部以外の辺に、該辺に対して斜め方向に形成するものであっても良い。 As described above, in the present invention, the printed circuit board unit can be configured only by engaging the notches 8 and 9 of each support column 2 with the groove-shaped recesses 3 and 4 of each printed circuit board 1, so that the assembly workability is excellent. . Moreover, since the space where the thin support | pillar 2 on the printed circuit board 1 is inserted should just be made into the prohibition area | region which cannot mount an electronic component, the area efficiency which can mount the component of the printed circuit board 1 can be improved. In particular, for the two corners, it is possible to secure a wide mounting area by effectively using the forbidden regions of the corners. Furthermore, by forming the recess 3 in an oblique direction with respect to the side 5, the distance from the side 5 of the printed circuit board 1 to the tip of the recess 3 is shorter than when the recess 3 is formed at a right angle to the side 5. can do. For this reason, the area efficiency which can mount components can be improved more. The recess 3 may be formed on a side other than the corner of the printed board 1 in an oblique direction with respect to the side.
上記の実施形態によれば、従来のように工具を使用したり、接着剤で固定したりすることなく、プリント基板ユニットを構成することができる。特に上記のような３点支持構造とすれば、最小限の支柱２でがたつきなく複数のプリント基板１を支持させることができる。 According to the above embodiment, the printed circuit board unit can be configured without using a tool or fixing with an adhesive as in the prior art. In particular, if the three-point support structure is used as described above, a plurality of printed circuit boards 1 can be supported with the minimum support 2 without rattling.
また図５に示すように、プリント基板１の外径寸法に略一致するサイズのケース１０に全体を収納すれば、支柱２が外側に外れるおそれがなくなるので、より容易かつ確実にプリント基板ユニットを固定することができる。またプリント基板１をケース内壁まで拡大して成形できるので実装面積が増加する。 Further, as shown in FIG. 5, if the entire case is accommodated in the case 10 having a size substantially matching the outer diameter of the printed circuit board 1, there is no possibility that the support column 2 will come off, so that the printed circuit board unit can be more easily and reliably attached. Can be fixed. Moreover, since the printed circuit board 1 can be enlarged and molded to the inner wall of the case, the mounting area increases.
さらに図６に示すように、ケース１０の上蓋１１にゴムやスポンジ等の当て部材１２を設け、上蓋１１を閉めた状態で当て部座材１２を支柱２の上端に当接させることで、より効果的にがたつきを抑えることができる。 Further, as shown in FIG. 6, a contact member 12 such as rubber or sponge is provided on the upper cover 11 of the case 10, and the contact member seat 12 is brought into contact with the upper end of the support column 2 with the upper cover 11 closed. It can effectively suppress rattling.
上記した支柱２の材質をプリント基板１と同質材とすれば、プリント基板を成形するときに、同時に支柱２も成形することができる。具体的には、図７に示すように一枚の板状の樹脂部材内に複数の支柱２とプリント基板１を一体に成形するようにすれば、プリント基板ユニットの生産効率を著しく高めることができる。 If the material of the above-described support 2 is the same material as that of the printed circuit board 1, the support 2 can be formed at the same time as the printed circuit board is formed. Specifically, as shown in FIG. 7, if the plurality of support columns 2 and the printed circuit board 1 are integrally formed in one plate-like resin member, the production efficiency of the printed circuit board unit can be remarkably improved. it can.
なお図７に示されるように、薄肉部や空間部１３をプリント基板１や支柱２の周囲に形成すると、プリント基板１や支柱２を、成形体から手で折って容易に取り出すことができる。 As shown in FIG. 7, when the thin wall portion or the space portion 13 is formed around the printed circuit board 1 or the support column 2, the printed circuit board 1 or the support column 2 can be easily removed from the molded body by hand.
上記した実施形態ではプリント基板１を２段に積層したが、同様に３段以上に積層することも可能である。また支柱２の位置や凹部３、４の形成角度も、適宜変更しても差し支えない。 In the above-described embodiment, the printed circuit boards 1 are stacked in two stages. However, it is also possible to stack in three or more stages. Also, the position of the support column 2 and the formation angles of the recesses 3 and 4 may be appropriately changed.
