Description

本発明は、プリント基板のスタッキングコネクタ抜け止め構造に関する。   The present invention relates to a stacking connector retaining structure for a printed circuit board.

離間して平行に配置されたプリント基板間は、スタッキングコネクタを用いて連続して接続される。そして、使用中や輸送中の振動などでスタッキングコネクタが抜けないように、プリント基板間にスタッキングコネクタの抜け防止機構が備えられる（例えば、特許文献１、２）。   The printed circuit boards spaced apart and arranged in parallel are connected in series using a stacking connector. Then, a mechanism for preventing the removal of the stacking connector is provided between the printed circuit boards so that the stacking connector does not come off due to vibration or the like during use or transport (for example, Patent Documents 1 and 2).

特開平０７−１８３０５８号公報Unexamined-Japanese-Patent No. 07-183058 gazette 特開平０２−０３３８７５号公報JP 02-033875 A

特許文献１では、メイン基板に金属製の抜け止め板を備え、抜け止め板の上からサブ基板を嵌合している。そして、抜け止め板の押え突片の下面でサブ基板を上から抑えてスタッキングコネクタの抜け止めとしている。   In Patent Document 1, the main substrate is provided with a metal retaining plate, and the sub substrate is fitted from above the retaining plate. Then, the sub-substrate is held from above by the lower surface of the pressing projection of the retaining plate to prevent the stacking connector from being detached.

しかし、スタッキングコネクタの近くやプリント基板平面上の内側に、抜け止め板を実装するためのスルーホールやＦＧパターン（筐体グランドパターン）等を設けるため、配線できない領域が増えて、基板設計上の大きな制約となるおそれがある。   However, since through holes and FG patterns (chassis ground patterns) for mounting the retaining plate are provided near the stacking connector or on the inner side of the plane of the printed circuit board, the area where wiring can not be made increases, and the board design This may be a major limitation.

また、特許文献２では、複数のプリント基板間の間隔が同一寸法で接続されるスタッキングコネクタにおいて、プリント基板の同じ位置に長円穴を設け、この長円穴に、プリント基板を挟み込める２段の長円形状のロック部をプリント基板毎に持つロックシャフトを通している。そして、ロックシャフト（およびロック部）を９０°回転させることで、複数枚のプリント基板を一度にロックしている。   Further, in Patent Document 2, in a stacking connector in which intervals between a plurality of printed circuit boards are connected with the same dimension, an oval hole is provided at the same position of the printed circuit board, and two steps can be used to sandwich the printed circuit board in this oval hole. A lock shaft having an oval shaped lock portion for each printed circuit board is passed through. A plurality of printed circuit boards are locked at one time by rotating the lock shaft (and the lock portion) by 90 °.

しかし、特許文献１と同様に、スタッキングコネクタの近くやプリント基板平面上の内側に、ロックシャフトを通すための貫通穴およびロックシャフトとプリント基板との接触面に配線禁止領域を設けるため、配線できない領域が増えて基板設計上の大きな制約となるおそれがある。   However, similar to Patent Document 1, wiring can not be performed because a through hole for passing the lock shaft and a contact area between the lock shaft and the printed circuit board are provided near the stacking connector or on the inner side of the plane of the printed circuit board. There is a possibility that the area will increase and this will be a major constraint on the board design.

本発明は、上記事情に鑑みてなされたものであり、基板設計上の制約を抑制して、スタッキングコネクタの抜けを防止するプリント基板のスタッキングコネクタ抜け止め構造を提供することを目的としている。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a stacking connector retaining structure for a printed circuit board that prevents the removal of the stacking connector while suppressing restrictions on the board design.

本発明の実施形態に係るプリント基板のスタッキングコネクタ抜け止め構造について、図面に基づいて詳細に説明する。なお、実施形態の説明では、説明の便宜上、プリント基板が重ねられた方向を上下方向として説明するが、本発明は、プリント基板を上下に重ねて配置する態様に限定するものではない。   A stacking connector retaining structure for a printed circuit board according to an embodiment of the present invention will be described in detail based on the drawings. In the description of the embodiment, for convenience of explanation, the direction in which the printed circuit boards are overlapped will be described as the vertical direction, but the present invention is not limited to the aspect in which the printed circuit boards are vertically arranged.

図１に示すように、本発明の第１実施形態に係るプリント基板のスタッキングコネクタ抜け止め構造は、離間して平行に配置される複数のプリント基板１ａ、１ｂと、プリント基板１ａ、１ｂ間に備えられる抜け止め支柱２を備える。   As shown in FIG. 1, the stacking connector retaining structure for a printed circuit board according to the first embodiment of the present invention is provided between a plurality of printed circuit boards 1a and 1b and printed circuit boards 1a and 1b, which are spaced apart and arranged in parallel. It comprises a retaining post 2 provided.

下側のプリント基板１ａは、動かないように、端面が強固に固定される。上側のプリント基板１ｂは、例えば、２箇所（図中矢印Ａで示す）のみ固定され、片手持ちの状態となっている。プリント基板１ａ、１ｂにはそれぞれスタッキングコネクタ３ａ、３ｂが実装され、プリント基板１ａ、１ｂの組立時にスタッキングコネクタ３ａ、３ｂが嵌合される。また、上側のプリント基板１ｂの端部には、端子台４（外部インターフェース）が備えられる。なお、図１では、プリント基板１ａ、１ｂの抜け止め支柱２が設けられる端面の位置は、同じ位置（同一平面上の位置）となっているが、プリント基板１ａ、１ｂの端面は、必ずしも同じ位置である必要はない。例えば、プリント基板１ａ、１ｂの端面の位置が５ｍｍ程度ずれていても、抜け止め支柱２の形状を変更することで、スタッキングコネクタ３ａ、３ｂの抜けを防止することができる。   The end face of the lower printed circuit board 1a is firmly fixed so as not to move. The upper printed circuit board 1b is, for example, fixed at only two places (indicated by arrow A in the figure), and is in a single-handed state. Stacking connectors 3a and 3b are mounted on the printed circuit boards 1a and 1b, respectively, and the stacking connectors 3a and 3b are fitted when the printed circuit boards 1a and 1b are assembled. Further, a terminal block 4 (external interface) is provided at an end portion of the upper printed board 1b. In FIG. 1, the end faces of the printed circuit boards 1a and 1b on which the retaining columns 2 are provided are at the same position (in the same plane), but the end faces of the printed circuit boards 1a and 1b are necessarily the same. It does not have to be in position. For example, even if the positions of the end faces of the printed circuit boards 1a and 1b are deviated by about 5 mm, it is possible to prevent the stacking connectors 3a and 3b from being detached by changing the shape of the retaining post 2.

図２に示すように、抜け止め支柱２は、プリント基板１ａ、１ｂ間に架け渡して設けられる板部２ａを備える。板部２ａの上端部および下端部（長手方向の端部）には、それぞれ基板固定部２ｂが備えられる。基板固定部２ｂは、抜け止め支柱２の端部に備えられる端部側基板固定部２ｃと、端部側基板固定部２ｃと対向して設けられる内側基板固定部２ｄを備える。端部側基板固定部２ｃと内側基板固定部２ｄは、プリント基板１ａ（または、プリント基板１ｂ）の板厚分離間して設けられ、端部側基板固定部２ｃと内側基板固定部２ｄの間にプリント基板１ａ（または、プリント基板１ｂ）が嵌合される嵌合部２ｅが形成される。抜け止め支柱２は、例えば、嵌合部２ｅの深さｄ1＝２ｍｍ〜５ｍｍ程度、板部２ａの板厚ｔ1＝２ｍｍ〜５ｍｍ程度、幅ｗ1＝３ｍｍ〜２０ｍｍ程度、プリント基板１ａ、１ｂ間の距離ｈ1＝１０ｍｍ〜４０ｍｍ程度に形成される。 As shown in FIG. 2, the retaining post 2 includes a plate portion 2 a provided so as to bridge between the printed circuit boards 1 a and 1 b. The upper and lower ends (ends in the longitudinal direction) of the plate portion 2a are each provided with a substrate fixing portion 2b. The substrate fixing portion 2 b includes an end portion side substrate fixing portion 2 c provided at an end portion of the retaining post 2 and an inner substrate fixing portion 2 d provided to face the end portion side substrate fixing portion 2 c. The end portion side substrate fixing portion 2c and the inner substrate fixing portion 2d are provided between the thickness separation of the printed circuit board 1a (or printed substrate 1b), and between the end portion side substrate fixing portion 2c and the inner substrate fixing portion 2d. A fitting portion 2e to which the printed circuit board 1a (or the printed circuit board 1b) is fitted is formed on For example, the retaining post 2 has a depth d 1 of 2 mm to 5 mm of the fitting portion 2 e, a plate thickness t 1 of 2 mm to 5 mm of the plate portion 2 a, and a width w 1 of 3 mm to 20 mm; The distance h 1 between 1 b is approximately 10 mm to 40 mm.

抜け止め支柱２は、例えば、プリント基板１ａ、１ｂに用いられる絶縁材料（例えば、ガラス繊維にエポキシ樹脂を含浸させたもの等）や流通性の良い合成樹脂（例えば、ＡＢＳ樹脂（アクリロニトリル・ブタジエン・スチレン共重合合成樹脂））等により形成される。抜け止め支柱２を絶縁材料で形成することで、プリント基板１ａ、１ｂ上での絶縁距離を考慮する必要がなくなる。   The retaining post 2 is made of, for example, an insulating material (for example, a glass fiber impregnated with an epoxy resin) used for the printed circuit boards 1a and 1b or a synthetic resin having a good flowability (for example, an ABS resin (acrylonitrile butadiene, Styrene copolymer synthetic resin)) etc. By forming the retaining post 2 with an insulating material, it is not necessary to consider the insulation distance on the printed circuit boards 1a and 1b.

端部側基板固定部２ｃと内側基板固定部２ｄは、板部２ａから嵌合部２ｅに嵌め合わされるプリント基板１ａ（または、プリント基板１ｂ）側に突出して設けられる。内側基板固定部２ｄのプリント基板１ａ（または、プリント基板１ｂ）と接する面には、基板固定用の凸部２ｆが設けられる。また、内側基板固定部２ｄの基端部には、切欠き２ｇが形成される。例えば、内側基板固定部２ｄの基端部には、切欠き２ｇとして板部２ａの幅方向に延びる断面円弧状の溝が形成される。   The end-side substrate fixing portion 2c and the inner substrate fixing portion 2d are provided so as to protrude from the plate portion 2a to the printed board 1a (or printed board 1b) side fitted to the fitting portion 2e. The convex part 2f for board | substrate fixation is provided in the surface which contact | connects the printed circuit board 1a (or printed circuit board 1b) of the inner side board fixed part 2d. Moreover, the notch 2g is formed in the base end part of the inner side board | substrate fixing | fixed part 2d. For example, in the base end portion of the inner substrate fixing portion 2d, a groove having an arc-shaped cross section extending in the width direction of the plate portion 2a is formed as the notch 2g.

凸部２ｆは、例えば、内側基板固定部２ｄのプリント基板１ａ（または、プリント基板１ｂ）と接する面から半球状に突出して形成される。凸部２ｆは、例えば、嵌合部２ｅの開口端近傍であって、内側基板固定部２ｄの中央部に設けられる。凸部２ｆは、例えば、直径Ｒ1＝０．５ｍｍ〜２ｍｍ程度、高さＨ1＝０．２ｍｍ〜２ｍｍ程度の半球状に形成される。 The convex portion 2 f is formed, for example, in a hemispherical shape by projecting from the surface of the inner substrate fixing portion 2 d in contact with the printed board 1 a (or the printed board 1 b). The convex portion 2 f is provided, for example, in the vicinity of the opening end of the fitting portion 2 e and at the central portion of the inner substrate fixing portion 2 d. The convex portion 2 f is formed in a hemispherical shape having, for example, a diameter R 1 of about 0.5 mm to 2 mm and a height H 1 of about 0.2 mm to 2 mm.

図３（ａ）に示すように、プリント基板１ａの上にプリント基板１ｂが離間して備えられる。このとき、スタッキングコネクタ３ａ、３ｂが嵌合される。その後、抜け止め支柱２の下端部側の嵌合部２ｅにプリント基板１ａが嵌め合わされ、抜け止め支柱２の上端部側の嵌合部２ｅにプリント基板１ｂが嵌め合わされる。このようにして、プリント基板１ａ、１ｂの端部に抜け止め支柱２が設けられる。   As shown in FIG. 3A, the printed circuit board 1b is provided separately on the printed circuit board 1a. At this time, the stacking connectors 3a and 3b are fitted. Thereafter, the printed circuit board 1a is fitted to the fitting portion 2e on the lower end portion side of the retaining post 2 and the printed board 1b is fitted to the fitting portion 2e on the upper end portion side of the retaining strut 2. In this manner, the retaining post 2 is provided at the end of the printed circuit board 1a, 1b.

図３（ｂ）に示すように、プリント基板１ａには、貫通穴１ｃが形成される。そして、プリント基板１ａを抜け止め支柱２の嵌合部２ｅに嵌め合わせると、プリント基板１ａの貫通穴１ｃに、内側基板固定部２ｄに設けられた凸部２ｆが嵌め込まれて、プリント基板１ａから抜け止め支柱２が脱落することが防止される。なお、図３（ａ）に示すように、プリント基板１ｂにも同様の貫通穴１ｃが形成されており、内側基板固定部２ｄに設けられた凸部２ｆが貫通穴１ｃに嵌め込まれる。   As shown in FIG. 3B, through holes 1c are formed in the printed circuit board 1a. Then, when the printed circuit board 1a is fitted into the fitting portion 2e of the retaining column 2, the convex portion 2f provided on the inner substrate fixing portion 2d is fitted into the through hole 1c of the printed circuit board 1a. It is prevented that the retaining post 2 falls off. As shown in FIG. 3A, a similar through hole 1c is formed also in the printed circuit board 1b, and a convex portion 2f provided in the inner substrate fixing portion 2d is fitted into the through hole 1c.

図４に示すように、抜け止め支柱２の幅ｗ1＝５ｍｍ程度、嵌合部の深さｄ1＝２ｍｍ程度の場合、プリント基板１ａ（または、プリント基板１ｂ）の端面からｌ1＝１．３ｍｍ程度の位置に直径１ｍｍ程度の貫通穴１ｃが形成されることとなる。したがって、プリント基板１ａ、１ｂに貫通穴１ｃを形成することによる配線禁止領域は、プリント基板１ａ（または、プリント基板１ｂ）と抜け止め支柱２の端部側基板固定部２ｃ（または、内側基板固定部２ｄ）との接触部となる（図中斜線で示す）。なお、一般的に、プリント基板１ａ、１ｂの端から１ｍｍは配線禁止とされているので、抜け止め支柱２を１つ設けることにより増加する配線禁止領域は１ｍｍ×５ｍｍ程度となる。 As shown in FIG. 4, in the case where the width w 1 of the retaining post 2 is about 5 mm and the depth d 1 of the fitting part is about 2 mm, l 1 = 1 from the end face of the printed circuit board 1a (or printed circuit board 1b). A through hole 1c having a diameter of about 1 mm is formed at a position of about 3 mm. Therefore, the wiring prohibited area formed by forming the through holes 1c in the printed circuit boards 1a and 1b is the printed circuit board 1a (or printed circuit board 1b) and the end portion side substrate fixing portion 2c of the retaining post 2 (or inner substrate fixed) It becomes a contact portion with the portion 2d) (indicated by hatching in the figure). Generally, wiring is prohibited at 1 mm from the end of the printed circuit boards 1a and 1b, so the wiring prohibited area increased by providing one retaining post 2 is about 1 mm × 5 mm.

以上のような、本発明の第１実施形態に係るプリント基板のスタッキングコネクタ抜け止め構造によれば、プリント基板１ａ、１ｂの端部に抜け止め支柱２を備えることで、スタッキングコネクタ３ａ、３ｂの抜けを防止することができる。   According to the stacking connector retaining structure for a printed circuit board according to the first embodiment of the present invention as described above, by providing the retaining post 2 at the end of the printed circuit boards 1a and 1b, the stacking connectors 3a and 3b are provided. It is possible to prevent the omission.

また、抜け止め支柱２の嵌合部２ｅにプリント基板１ａ（または、プリント基板１ｂ）を嵌め込むことで、プリント基板１ａ、１ｂに抜け止め支柱２を容易に固定することができる。また、抜け止め支柱２とプリント基板１ａ、１ｂは、抜け止め支柱２の凸部２ｆとプリント基板１ａ（または、プリント基板１ｂ）の貫通穴１ｃの嵌め合わせにより固定されているため、外力を受けて抜け止め支柱２が脱落することが抑制される。   Further, by fitting the printed circuit board 1a (or the printed circuit board 1b) into the fitting portion 2e of the retaining column 2, the retaining column 2 can be easily fixed to the printed circuit boards 1a and 1b. Further, since the retaining column 2 and the printed circuit boards 1a and 1b are fixed by fitting the convex portion 2f of the retaining column 2 and the through hole 1c of the printed circuit board 1a (or printed circuit board 1b), external force is received. As a result, the falling off of the retaining post 2 is suppressed.

また、内側基板固定部２ｄの基端部に切欠き２ｇを形成することで、大きな力を必要とすることなく、プリント基板１ａ、１ｂに抜け止め支柱２を取付け（取り外し）作業を行うことができる。   In addition, by forming the notch 2g in the base end of the inner substrate fixing portion 2d, it is possible to attach (remove) the retaining post 2 to the printed circuit boards 1a and 1b without requiring a large force. it can.

図１に示すように、プリント基板１ｂに設けられた端子台４を操作すると、プリント基板１ｂの固定箇所（図中矢印Ａで示す）からプリント基板１ｂの端までの部分が変形して、スタッキングコネクタ３ａ、３ｂが抜ける方向（図中矢印Ｂで示す）に力が作用し、スタッキングコネクタ３ａ、３ｂが抜けるおそれがある。そこで、プリント基板１ａ、１ｂの端部に抜け止め支柱２を取り付け、プリント基板１ａとプリント基板１ｂの端部間距離を拘束することで、スタッキングコネクタ３ａ、３ｂの抜けを防止することができる。   As shown in FIG. 1, when the terminal block 4 provided on the printed circuit board 1b is operated, the portion from the fixed portion (indicated by arrow A in the figure) of the printed circuit board 1b to the end of the printed circuit board 1b is deformed and stacking is performed. A force acts in the direction in which the connectors 3a and 3b come off (indicated by the arrow B in the figure), and the stacking connectors 3a and 3b may come off. Therefore, the retaining posts 2 are attached to the end portions of the printed circuit boards 1a and 1b, and the distance between the end portions of the printed circuit board 1a and the printed circuit board 1b is restricted, whereby the detachment of the stacking connectors 3a and 3b can be prevented.

また、抜け止め支柱２を設けることによるプリント基板１ａ、１ｂの配線禁止領域の増加は非常に少なく、従来技術と比較して、抜け止め支柱２を設けることによる基板設計上の制約がかからない。   Further, the increase in the wiring prohibited area of the printed circuit boards 1a and 1b due to the provision of the retaining post 2 is very small, and there is no restriction on the board design due to the provision of the retaining post 2 compared to the prior art.

図７（ａ）に示すように、プリント基板１ａの上にプリント基板１ｂが離間して備えられる。このとき、スタッキングコネクタ３ａ、３ｂが嵌合される。その後、抜け止め支柱５の下側に設けられた一対の基板固定部５ｂの嵌合部５ｅと基板挟持部５ｇの嵌合部５ｊにプリント基板１ａが嵌め合わされる。また、抜け止め支柱５の上側に設けられた一対の基板固定部５ｂの嵌合部５ｅと基板挟持部５ｇの嵌合部５ｊにプリント基板１ｂが嵌め合わされる。このようにして、プリント基板１ａ、１ｂの端部に抜け止め支柱５が設けられる。   As shown in FIG. 7A, the printed circuit board 1b is provided separately on the printed circuit board 1a. At this time, the stacking connectors 3a and 3b are fitted. Thereafter, the printed circuit board 1a is fitted to the fitting portion 5e of the pair of substrate fixing portions 5b provided below the retaining column 5 and the fitting portion 5j of the substrate holding portion 5g. The printed circuit board 1b is fitted to the fitting portion 5e of the pair of substrate fixing portions 5b provided on the upper side of the retaining post 5 and the fitting portion 5j of the substrate holding portion 5g. In this manner, the retaining post 5 is provided at the end of the printed circuit board 1a, 1b.

第１実施形態と同様に、プリント基板１ａ、１ｂには、基板固定部５ｂが備えられる箇所に貫通穴１ｃが形成され、この貫通穴１ｃに基板固定部５ｂの凸部５ｆが嵌め合わされる。   As in the first embodiment, through holes 1c are formed in the printed circuit boards 1a and 1b at locations where the substrate fixing portions 5b are provided, and the convex portions 5f of the substrate fixing portions 5b are fitted into the through holes 1c.

また、図７（ｂ）に示すように、抜け止め支柱５の基板挟持部５ｇの嵌合部５ｊにプリント基板１ａ（または、プリント基板１ｂ）が嵌め込まれることで、嵌合部５ｊ内に設けられた凸部５ｋがプリント基板１ａ（または、プリント基板１ｂ）に食い込み、プリント基板１ａ（または、プリント基板１ｂ）が強固に固定される。   Further, as shown in FIG. 7B, the printed circuit board 1a (or the printed circuit board 1b) is fitted into the fitting portion 5j of the substrate holding portion 5g of the retaining column 5 to provide the inside of the fitting portion 5j. The projected portion 5k bites into the printed circuit board 1a (or printed circuit board 1b), and the printed circuit board 1a (or printed circuit board 1b) is firmly fixed.

図８に示すように、抜け止め支柱５を備えることによるプリント基板１ａ、１ｂの配線禁止領域は、プリント基板１ａ（または、プリント基板１ｂ）と端部側基板固定部５ｃ（または、内側基板固定部５ｄ）の接触部と、プリント基板１ａ（または、プリント基板１ｂ）と端部側基板挟持部５ｈ（または、内側基板挟持部５ｉ）の接触部である（図中斜線で示す）。一般的に、プリント基板１ａ、１ｂの端から１ｍｍは配線禁止とされているので、基板挟持部５ｇの嵌合部５ｅの深さｄ2＝１ｍｍ程度とすることで、抜け止め支柱５を設けることにより増加する正味の配線禁止領域は、第１実施形態の抜け止め支柱２と同じとなる。 As shown in FIG. 8, the wiring inhibited area of the printed circuit boards 1a and 1b by providing the retaining pillars 5 is the printed circuit board 1a (or printed circuit board 1b) and the end side substrate fixing portion 5c (or inner substrate fixed) The contact portion of the portion 5d) is the contact portion between the printed circuit board 1a (or printed circuit board 1b) and the end-side substrate pinching portion 5h (or inner substrate pinching portion 5i) (shown by hatching in the figure). Generally, wiring is prohibited at 1 mm from the end of the printed circuit boards 1a and 1b, so the retaining post 5 is provided by setting the depth d 2 of the fitting portion 5e of the substrate holding portion 5g to about 1 mm. The net wiring prohibited area thus increased is the same as the retaining post 2 of the first embodiment.

以上のような、本発明の第２実施形態に係るプリント基板のスタッキングコネクタ抜け止め構造によれば、プリント基板１ａ、１ｂの端部に抜け止め支柱５を備えることで、スタッキングコネクタ３ａ、３ｂの抜けを防止することができる。   As described above, according to the stacked connector retaining structure for a printed circuit board according to the second embodiment of the present invention, by providing the retaining post 5 at the end of the printed circuit boards 1a and 1b, the stacking connectors 3a and 3b are provided. It is possible to prevent the omission.

第１実施形態の抜け止め支柱２と同様に、抜け止め支柱５の嵌合部５ｅ、５ｊにプリント基板１ａ（または、プリント基板１ｂ）を嵌め合わせることで、容易にプリント基板１ａ、１ｂに抜け止め支柱５を備えることができる。また、プリント基板１ａ、１ｂの貫通穴１ｃに基板固定部５ｂの凸部５ｆを嵌め合わせることで、容易にプリント基板１ａ、１ｂに抜け止め支柱５を固定することができ、外力を受けても抜け止め支柱５がプリント基板１ａ、１ｂから脱落することが抑制される。   Similar to the retaining post 2 of the first embodiment, the printed board 1a (or the printed board 1b) is fitted to the fitting portions 5e, 5j of the retaining post 5 so that the printed board 1a, 1b can be easily removed. A stop post 5 can be provided. Further, by fitting the convex portion 5f of the substrate fixing portion 5b into the through hole 1c of the printed circuit boards 1a and 1b, the retaining post 5 can be easily fixed to the printed circuit boards 1a and 1b. It is suppressed that the retaining post 5 falls off the printed circuit boards 1a and 1b.

また、基板挟持部５ｇの凸部５ｋがプリント基板１ａ（または、プリント基板１ｂ）に食い込むことで、プリント基板１ａ（または、プリント基板１ｂ）が抜け止め支柱５に強固に固定される。   In addition, the convex portion 5k of the substrate sandwiching portion 5g bites into the printed circuit board 1a (or the printed circuit board 1b), whereby the printed circuit board 1a (or the printed circuit board 1b) is firmly fixed to the retaining post 5.

また、抜け止め支柱５を設けることによるプリント基板１ａ、１ｂの配線禁止領域の増加は、非常に少なく、従来技術と比較して、抜け止め支柱５を設けることにより、基板設計上の制約がかからない。特に、基板挟持部５ｇの板部５ａからの突出距離を基板固定部５ｂの突出距離よりも短くすることで、抜け止め支柱５を備えることによるプリント基板１ａ、１ｂの配線禁止領域の増加を抑制することができる。さらに、基板挟持部５ｇの嵌合部５ｊの深さｄ3を１ｍｍ以下とすることで、プリント基板１ａ、１ｂの配線禁止領域を増加させることなくプリント基板１ａ、１ｂを支持することができる。 Further, the increase in the wiring prohibited area of the printed circuit boards 1a and 1b due to the provision of the retaining pillars 5 is very small, and there is no restriction on the board design due to the provision of the retaining pillars 5 as compared with the prior art. . In particular, the protrusion distance of the substrate holding portion 5g from the plate portion 5a is made shorter than the protrusion distance of the substrate fixing portion 5b, thereby suppressing an increase in the wiring prohibited area of the printed circuit boards 1a and 1b by providing the retaining pillars 5. can do. Further, the depth d 3 of the fitting portion 5j of the substrate holding portions 5g With 1mm or less, it is possible to support the printed circuit board 1a, 1b, without increasing PCB 1a, the wiring inhibited area 1b.
