本考案は、回路基板を多数並列させて伝導冷却可能に固定する回路基板固定用 シェルフ構造に関するものである。 The present invention relates to a shelf structure for fixing a circuit board, in which a large number of circuit boards are arranged in parallel so as to be conductively cooled.
【０００２】[0002]
電子機器では色々な回路素子部品が組み込まれ、その中には使用時に発熱する もの、すなわち発熱素子も多数用いられている。したがって、これら発熱素子を 実装してなる回路基板が搭載された電子機器では、発熱素子の放熱を効率良く行 い、高密度で、かつ着脱自在に回路基板を搭載できる構造が要求されている。 In electronic devices, various circuit element parts are incorporated, and many of them generate heat during use, that is, many heating elements are used. Therefore, in an electronic device equipped with a circuit board on which these heat generating elements are mounted, a structure capable of efficiently dissipating heat from the heat generating elements and having a high density and detachably mounting the circuit board is required.
【０００３】 図６は、従来の回路基板固定用シェルフ構造の一例を示す要部斜視図で、図７ はこのシェルフ構造を概略的に示した全体外観図である。 図６および図７において、このシェルフ１００は、上下の側面と左右の側面お よび前後面を有した六面体で形成され、回路基板１を出し入れする前面は開口さ せている。また、上下の側面にはそれぞれ熱伝導性冷却用ブロック１０１が設け られ、この上下の熱伝導性冷却用ブロック１０１で回路基板１の両端を固定支持 できるようになっている。FIG. 6 is a perspective view of an essential part showing an example of a conventional shelf structure for fixing a circuit board, and FIG. 7 is an overall external view schematically showing this shelf structure. 6 and 7, the shelf 100 is formed of a hexahedron having upper and lower side surfaces, left and right side surfaces, and front and rear surfaces, and the front surface for inserting and removing the circuit board 1 is open. Further, heat conductive cooling blocks 101 are provided on the upper and lower side surfaces, respectively, and both ends of the circuit board 1 can be fixedly supported by the upper and lower heat conductive cooling blocks 101.
【０００４】 さらに詳述すると、各熱伝導性冷却用ブロック１０１には、左右側面方向に向 かって点在するようにして、一定の間隔毎に凹溝１０２（図６参照）が回路基板 １の着脱方向（この場合では前後方向）に延びた状態で形成されている。また、 各凹溝１０２の底面１０２ｃの左右両側には、凹溝１０２の左右両側面１０２ａ ，１０２ｂより底面１０２ｃ内へそれぞれ延長した状態で嵌合溝１０３が設けら れ、この各嵌合溝１０３内に各回路基板１の端部が前面開口側より緩くスライド 挿入可能になっている。なお、嵌合溝１０３内に端部が挿入されてシェルフ１０ ０内に配置された回路基板１は、さらに当て金具１０４と押え部材１０５とで凹 溝１０２内の側面１０２ａ（または１０２ｂ）に押し付けられて強固に固定され る。More specifically, in each of the heat conductive cooling blocks 101, concave grooves 102 (see FIG. 6) are provided at regular intervals in the circuit board 1 so as to be scattered toward the left and right side surfaces. It is formed so as to extend in the attachment / detachment direction (in this case, the front-back direction). Fitting grooves 103 are provided on the left and right sides of the bottom surface 102c of each groove 102 so as to extend from the left and right side surfaces 102a and 102b of the groove 102 into the bottom surface 102c. The end portion of each circuit board 1 can be slidably inserted therein from the front opening side. The circuit board 1 whose end is inserted into the fitting groove 103 and placed in the shelf 100 is further pressed against the side surface 102a (or 102b) in the concave groove 102 by the metal fitting 104 and the pressing member 105. It is fixed firmly.
【０００５】 上記当て金具１０４は、それぞれ内側に上方（または下方）に向かうに従って 次第に回路基板１に近づく状態で傾斜するテーパ面１０６を有し、横断面が略台 形をなして形成されている。そして、この当て金具１０４は、凹溝１０３内で回 路基板１の内側に配置されるようにして、各凹溝１０３内毎に左右に別れて一対 ずつ配置される。The metal fittings 104 each have a tapered surface 106 that inclines inwardly toward the circuit board 1 as it goes upward (or downward), and its cross section is formed in a substantially trapezoidal shape. .. Then, the metal fittings 104 are arranged inside the concave groove 103 inside the circuit board 1 so as to be arranged in pairs in left and right in each concave groove 103.
【０００６】 一方、上記押え部材１０５は、凹溝１０３内で一対の当て金具１０４の間に介 装されるもので、左右両側には当て金具１０４のテーパ面１０６と対応するテー パ面１０７が形成されており、断面逆台形状に形成されている。加えて、この押 え部材１０５には、熱伝導性冷却用ブロック１０１の図示せぬバカ穴を通った止 めねじ１０８をねじ止めするための図示せぬねじ穴が設けられていて、この止め ねじ１０８で押え部材１０５を熱伝導性冷却用ブロック１０１の外側より締め付 け固定できる状態になっている。On the other hand, the pressing member 105 is interposed between a pair of metal fittings 104 in the concave groove 103, and a taper surface 106 corresponding to the tapered surface 106 of the metal fitting 104 is provided on both left and right sides. It is formed and has a reverse trapezoidal cross section. In addition, the holding member 105 is provided with a screw hole (not shown) for screwing the set screw 108 that has passed through the stupid hole (not shown) of the heat conductive cooling block 101. The pressing member 105 can be tightened and fixed from the outside of the heat conductive cooling block 101 with the screw 108.
【０００７】 次に、このシェルフ構造の回路基板固定動作を説明する。 まず、回路基板１を装着する場合は、止めねじ１０８の締め付けを緩める。そ して、当て金具１０４と凹溝１０２の側面１０２ａ，１０２ｂとの間にそれぞれ 回路基板１を配置させ、次いで各回路基板１の端部を対応する嵌合溝１０３内に スライド挿入させる。すると、これにより、各回路基板１はシェルフ１００内に 仮装着された状態になる。次いで、上下の熱伝導性冷却用ブロック１０１の外側 より各止めねじ１０８を締め付ける。すると、この締め付けによって押え部材１ ０５が熱伝導性冷却用ブロック１０１側に移動する。また、この移動で、押え部 材１０５の断面逆台形状のテーパ面１０７によって左右の当て金具１０４が図６ 中の矢印Ａ，Ｂ方向に押し広げられ、同時に各回路基板１が凹溝１０２の側面１ ０２ａ，１０２ｂに強く押し付けられて固定される。この操作は、各凹溝１０２ 毎に行われる。そして、このようにして取り付けられた回路基板１では、この回 路基板１上の発熱素子が発熱されると、この熱が冷却されている熱伝導性冷却用 ブロック１０１側に熱伝導して順次放熱される。Next, a circuit board fixing operation of this shelf structure will be described. First, when the circuit board 1 is mounted, the set screw 108 is loosely tightened. Then, the circuit boards 1 are respectively arranged between the metal fittings 104 and the side surfaces 102a and 102b of the concave groove 102, and then the ends of the respective circuit boards 1 are slid and inserted into the corresponding fitting grooves 103. Then, as a result, each circuit board 1 is temporarily mounted in the shelf 100. Then, each set screw 108 is tightened from the outside of the upper and lower heat conductive cooling blocks 101. Then, due to this tightening, the pressing member 105 moves toward the heat conductive cooling block 101 side. Also, by this movement, the left and right metal fittings 104 are expanded in the directions of arrows A and B in FIG. 6 by the tapered surface 107 of the pressing member 105 having an inverted trapezoidal cross section, and at the same time, the respective circuit boards 1 form the concave grooves 102. The side surfaces 102a and 102b are strongly pressed and fixed. This operation is performed for each groove 102. Then, in the circuit board 1 thus mounted, when the heating element on the circuit board 1 generates heat, this heat is conducted to the side of the heat conductive cooling block 101 which is being cooled and sequentially. Heat is dissipated.
【０００８】 これに対して、この回路基板１をメンテナンス等でシェルフ１００より取り外 す場合は、止めねじ１０８の締め付けを緩める。すると、回路基板１が熱伝導性 冷却用ブロック１０１の側面１０２ａ，１０２ｂに押し付けられている力が弱め られ、これによって回路基板１を嵌合溝１０３内より引き抜いて取り外すことが 可能になる。On the other hand, when the circuit board 1 is removed from the shelf 100 for maintenance or the like, the set screw 108 is loosened. Then, the force with which the circuit board 1 is pressed against the side surfaces 102a and 102b of the heat conductive cooling block 101 is weakened, and the circuit board 1 can be pulled out from the fitting groove 103 and removed.
【０００９】[0009]
しかしながら、上述した従来の回路基板固定用シェルフ構造では、回路基板１ を脱着するとき、図７に示すように、回路基板１の脱着方向を示す矢印Ｃに対し て、これと直交する矢印Ｄ方向より止めねじ１０８を締め付け、あるいは緩める 作業を行う必要がある。このため、メンテナンス作業がしづらく、しかもメンテ ナンス用のスペースを矢印Ｃ側に加えて、矢印Ｄ側にも余分に取らなくてはなら ないと言う問題点があった。 また、止めねじ１０８が１箇所では回路基板１の固定が不十分であるので、数 箇所に設ける必要があり、このため組立工数が多くなって作業性が悪いと言う問 題点があった。 However, in the conventional shelf structure for fixing a circuit board described above, when the circuit board 1 is attached and detached, as shown in FIG. 7, the arrow D direction orthogonal to the arrow C indicating the attachment and detachment direction of the circuit board 1 It is necessary to further tighten or loosen the set screw 108. Therefore, there is a problem that the maintenance work is difficult, and that a space for maintenance is required to be added to the arrow C side and an extra space is also required to the arrow D side. Further, since the fixing of the circuit board 1 is insufficient at one place with the set screw 108, it is necessary to provide the set screw at several places, which results in a large number of assembling steps and poor workability.
【００１０】 本考案は、上記問題点に鑑みてなされたものであり、その目的は回路基板の着 脱作業を簡単にすることのできる回路基板固定用シェルフ構造を提供することに ある。The present invention has been made in view of the above problems, and an object of the present invention is to provide a shelf structure for fixing a circuit board, which makes it possible to easily attach and detach the circuit board.
【００１１】[0011]
上記目的を達成するため、本考案に係る回路基板固定用シェルフ構造は、回路 基板の端部の受け入れを許容する凹溝を有した熱伝導冷却用熱伝導性冷却用ブロ ックを備えるとともに、前記凹溝内で固定金具を介して前記回路基板を前記凹溝 の一側壁に押し付け、前記回路基板を前記伝導冷却用熱伝導性冷却用ブロックに 着脱自在に固定してなるものであって、前記固定金具を、前記回路基板と共に前 記凹溝内に挿入されるとともに、圧縮されると少なくとも左右両側面が外側に膨 らんで前記回路基板を前記凹溝の側壁側に押し付ける弾性部材と、操作部分を前 記弾性部材の抜き差し側に配して前記弾性部材に取り付けられているとともに、 前記操作部分を回転させるとこの回転量に応じた分だけ前記弾性材を締め付け圧 縮させて前記膨らみ量を調整可能な締め付けねじ部材とで構成したものである。 In order to achieve the above-mentioned object, the shelf structure for fixing a circuit board according to the present invention is provided with a heat conduction cooling block for heat conduction cooling, which has a groove for allowing the end of the circuit board to be received. In the groove, the circuit board is pressed against one side wall of the groove via a fixing bracket, and the circuit board is detachably fixed to the heat conduction cooling block for conduction cooling. An elastic member that inserts the fixing metal together with the circuit board into the groove and presses the circuit board toward the side wall of the groove when at least both left and right side surfaces bulge outward when compressed. The operating portion is attached to the elastic member by arranging the operating portion on the insertion / removal side of the elastic member, and when the operating portion is rotated, the elastic member is tightened and compressed by an amount corresponding to the rotation amount, and the expansion is performed. Which is constituted by an adjustable clamping screw members only amounts.
【００１２】[0012]
この構成によれば、回路基板を熱伝導性冷却用ブロックの凹溝内に挿入させた 状態で、回路基板の着脱操作面側に設けられている操作部分を介して締め付けね じ部材を回転させると、この回転量に応じた分だけ弾性部材が締め付けられて、 この弾性部材の左右両側面が外側に膨らんで回路基板を押し、この力で回路基板 を凹溝の側壁に押し付けてシェルフに回路基板を確実に固定することができる。 同時に、この固定状態では回路基板側で発生した熱が、冷却されている熱伝導性 冷却用ブロック側へ伝導されて放熱される。一方、回路基板が固定されている状 態で、締め付けねじ部材による締め付けを緩めると、これに応じて弾性部材の膨 らみ量が減少し、回路基板を凹溝の側壁に押し付けている力が弱められ、これに よって回路基板を引き抜いて外すことができる。 According to this configuration, the tightening screw member is rotated through the operation portion provided on the attachment / detachment operation surface side of the circuit board with the circuit board inserted in the concave groove of the heat conductive cooling block. Then, the elastic member is tightened by the amount corresponding to this rotation amount, the left and right side surfaces of the elastic member bulge outward and push the circuit board, and this force pushes the circuit board against the side wall of the groove to form the circuit on the shelf. The substrate can be securely fixed. At the same time, in this fixed state, the heat generated on the side of the circuit board is conducted to the side of the heat conductive cooling block being cooled and radiated. On the other hand, if the tightening by the tightening screw member is loosened while the circuit board is fixed, the amount of expansion of the elastic member decreases accordingly, and the force pressing the circuit board against the side wall of the groove is reduced. It is weakened, which allows the circuit board to be pulled out and removed.

【００１４】 そして、この本考案の実施例において、シェルフ２は、図４に概略全体構造を 示すように、上下・左右の各側面および前後面を有した六面体で形成されており 、回路基板１を出し入れする前面は開口されている。また、上下の側面にはそれ ぞれ熱伝導性冷却用ブロック３が設けられ、この上下の熱伝導性冷却用ブロック ３で回路基板１の両端を固定できるようになっている。In this embodiment of the present invention, the shelf 2 is formed of a hexahedron having upper and lower side surfaces, left and right side surfaces, and front and rear surfaces, as shown in the schematic overall structure of FIG. The front surface for taking in and out is open. Further, heat conductive cooling blocks 3 are provided on the upper and lower side surfaces, respectively, and both ends of the circuit board 1 can be fixed by the upper and lower thermal conductive cooling blocks 3.
【００１５】 さらに詳述すると、各熱伝導性冷却用ブロック３には、左右の両側面方向に順 次一定の間隔で、凹溝４が回路基板１の着脱方向（この実施例では前後方向）に 延びた状態で複数形成されている。また、各熱伝導性冷却用ブロック３の前面に は、後面側に向かって穿設された係合穴５が各凹溝４毎に設けられている。加え て、各熱伝導性冷却用ブロック３の後面側には、各凹溝４毎に対応して、上下に 貫通する貫通穴６（図５参照）が２つずつ設けられている。そして、この各凹溝 ４内には回路基板１をそれぞれ配設させることができ、これによりシェルフ２内 には回路基板１が多数並列に搭載できるようになっており、また回路基板１が搭 載される各凹溝４内には固定金具７が取り付けられている。More specifically, in each of the heat conductive cooling blocks 3, the concave grooves 4 are arranged in the left and right side surfaces at regular intervals in the order of attachment and detachment of the circuit board 1 (front and rear direction in this embodiment). A plurality of them are formed in a state of extending to. Further, on the front surface of each heat conductive cooling block 3, an engagement hole 5 is formed for each recessed groove 4 and is formed toward the rear surface side. In addition, two through holes 6 (see FIG. 5) penetrating vertically are provided on the rear surface side of each heat conductive cooling block 3 in correspondence with each groove 4. Then, the circuit boards 1 can be arranged in the respective recessed grooves 4, whereby a large number of circuit boards 1 can be mounted in parallel in the shelf 2, and the circuit boards 1 can be mounted. A fixing metal fitting 7 is attached in each groove 4 to be placed.
【００１６】 その固定金具７は、この凹溝４の左右両側面４ａ，４ｂとの間に少なくとも回 路基板１の厚み寸法よりも大きな隙間が作られる状態にして凹溝４内に配設され る弾性を有した弾性部材８と、この弾性部材８の前後端にわたって配設された締 め付けねじ部材１６とで構成されている。The fixing metal fitting 7 is arranged in the concave groove 4 such that a gap larger than at least the thickness dimension of the circuit board 1 is formed between the right and left side surfaces 4 a and 4 b of the concave groove 4. The elastic member 8 has elasticity and the tightening screw member 16 is provided over the front and rear ends of the elastic member 8.
【００１７】 このうち、弾性部材８はゴム等で、断面が略四角形をした 細長い棒状に形成 されており、中央部分には上下面側に貫通している細長いスリット９が設けられ ている。加えて、スリット９の左右の内面には、切欠溝１０が前後２箇所ずつ合 計４つ設けられ、この切欠溝１０の部分で弾性部材８の両側面８ａ，８ｂが屈曲 変形し易く形成されている。また、弾性部材８の上面（または下面）の後端側に は、熱伝導性冷却用ブロック３の貫通穴６に対応して、２つのねじ穴１１が設け られている。これに対して、前端側には、上面（または下面）より直角に上方（ または下方）に延びる位置決め壁１２が設けられており、この位置決め壁１２の 内面に後端側へ向かって延びる係合ピン１３が熱伝導性冷却用ブロック３の係合 穴５と対応して一体に形成されている。加えて、弾性部材８には、貫通穴１４が 前後端にわたって設けられているとともに、この貫通穴１４の後端側における一 部にねじ溝１５が刻設されている。Among them, the elastic member 8 is made of rubber or the like, and is formed in an elongated rod shape having a substantially quadrangular cross section, and an elongated slit 9 penetrating to the upper and lower surfaces is provided in the central portion. In addition, a total of four notch grooves 10 are provided on each of the left and right inner surfaces of the slit 9 in front and rear positions, and both side surfaces 8a and 8b of the elastic member 8 are easily bent and deformed at the notch groove 10 portions. ing. Two screw holes 11 are provided on the rear end side of the upper surface (or lower surface) of the elastic member 8 so as to correspond to the through holes 6 of the heat conductive cooling block 3. On the other hand, on the front end side, there is provided a positioning wall 12 that extends upward (or downward) at right angles to the upper surface (or lower surface), and the inner surface of the positioning wall 12 extends toward the rear end. The pin 13 is formed integrally with the engaging hole 5 of the heat conductive cooling block 3. In addition, the elastic member 8 is provided with a through hole 14 extending over the front and rear ends thereof, and a thread groove 15 is formed in a part of the through hole 14 on the rear end side.
【００１８】 一方、締め付けねじ部材１６は、弾性部材８の貫通穴１４に、位置決め壁１２ 側から挿入されて取り付けられているものであって、細長いビスとして形成され ている。また、この締め付けねじ部材１６の先端部分には、貫通穴１４のねじ溝 １５と螺合されるねじ部１７が刻設されているとともに、他端側にはドライバー （不図示）でねじ込み操作される頭となる操作部分１８が設けられている。そし て、この締め付けねじ部材１６は、通常、弾性部材８の貫通穴１４に取り付けら れたままで取り扱われるものであって、ドライバーで操作部分１８がねじ込まれ る方向に回転されると、ねじ部１７がねじ溝１５内で後端側（図２中の矢印Ｘ方 向）へ送られることによって締め付けねじ部材１６の全体が後端側へ始動し、操 作部分１８とねじ溝１５との間の弾性部材８を圧縮させる。すると、この圧縮で 弾性部材８の両側面８ａ，８ｂが外側へ膨らむ状態に屈曲される。また、逆に操 作部分１８を反対方向に回転させると、ねじ部１７がねじ溝１５内で前端側へ送 られ、この間における弾性部材８の圧縮を解き、弾性部材８の両側面８ａ，８ｂ の外側への膨らみを減らすことができるようになっている。On the other hand, the tightening screw member 16 is inserted into the through hole 14 of the elastic member 8 from the positioning wall 12 side and attached, and is formed as an elongated screw. A screw portion 17 to be screwed into the screw groove 15 of the through hole 14 is engraved at the tip of the tightening screw member 16, and the other end side is screwed by a driver (not shown). An operating portion 18 serving as a head is provided. Then, the tightening screw member 16 is normally handled while being attached to the through hole 14 of the elastic member 8, and when the operating portion 18 is rotated by the screwdriver, the screw portion By sending 17 to the rear end side (in the direction of arrow X in FIG. 2) in the thread groove 15, the entire tightening screw member 16 is started to the rear end side, and between the operating portion 18 and the thread groove 15. The elastic member 8 is compressed. Then, both sides 8a and 8b of the elastic member 8 are bent by this compression so as to bulge outward. On the contrary, when the operation portion 18 is rotated in the opposite direction, the screw portion 17 is sent to the front end side in the screw groove 15, the compression of the elastic member 8 is released during this period, and both side surfaces 8a and 8b of the elastic member 8 are released. It is designed to reduce the outward bulge.
【００１９】 また、このようにして、弾性部材８と締め付けねじ部材１６とを一体に組み付 けて構成された固定金具５は、回路基板１が取り付けられる凹溝４内毎に予め取 り付けておいても、あるいは後から取り付けても良いもので、この実施例では凹 溝４内に回路基板１を挿入させた後から固定金具７を取り付ける方法を採ってい る。In addition, the fixing metal fitting 5 configured by integrally assembling the elastic member 8 and the tightening screw member 16 in this manner is preliminarily mounted in each recessed groove 4 in which the circuit board 1 is mounted. It may be set in advance or may be attached later. In this embodiment, the method of attaching the fixing metal 7 after inserting the circuit board 1 into the groove 4 is adopted.
【００２０】 次に、このシェルフ構造の回路基板固定動作を説明する。 まず、決められた凹溝４内に、一対の回路基板１を前面側よりそれぞれ左右両 側面４ａ，４ｂに当接させて挿入する（図３参照）。次いで、図３に示すように 、弾性部材８に対する締め付けねじ部材１６のねじ込みによる締め付け量を緩め た状態で、かつ係合ピン１３を係合穴５に対応させて、固定金具５を一対の回路 基板１の間に挿入させる。また、ねじ穴１１と貫通穴６とが対応した位置で、固 定用のシェルフ２の外側よりビス１９をねじ込んで締め付ける。すると、係合ピ ン１３の先端が係合穴５内に少しだけ挿入されて位置決めされた状態で、この固 定金具７が凹溝４内に固定される。図２および図５は、この状態を示している。 しかし、この状態では、未だ弾性部材８の両側面８ａ，８ｂは、回路基板１に強 く当接されていない。Next, a circuit board fixing operation of this shelf structure will be described. First, the pair of circuit boards 1 are inserted into the determined groove 4 from the front side so as to abut on the left and right side surfaces 4a and 4b respectively (see FIG. 3). Next, as shown in FIG. 3, with the tightening amount of the tightening screw member 16 screwed into the elastic member 8 being loosened and the engaging pin 13 corresponding to the engaging hole 5, the fixing metal fitting 5 is connected to the pair of circuits. It is inserted between the substrates 1. Further, at the position where the screw hole 11 and the through hole 6 correspond to each other, the screw 19 is screwed in from the outside of the fixing shelf 2 and tightened. Then, with the tip of the engaging pin 13 being slightly inserted into the engaging hole 5 and positioned, the fixing fitting 7 is fixed in the groove 4. 2 and 5 show this state. However, in this state, the both side surfaces 8a and 8b of the elastic member 8 are not yet in strong contact with the circuit board 1.
【００２１】 次いで、前面側に向いて突出している締め付けねじ部材１６の操作部分１８を ドライバーで締め付け方向（時計回り方向）に回すと、締め付けねじ部材１６が 図２中の矢印Ｘ方向にねじ込まれ、これに伴って弾性部材８が圧縮される。する と、この圧縮量に比例して切欠溝１０の部分で弾性部材８が略くの字状に屈曲さ れて行き、この弾性部材８の両側面８ａ，８ｂが外側、すなわち回路基板１側（ 図１中の矢印Ｚ方向）へ膨らんだ状態に変形し、この両側面８ａ，８ｂが回路基 板１を凹溝４の内面４ａ，４ｂにそれぞれ押し付ける。すると、この押し付け力 で回路基板１が凹溝４内に固定される。図１は、この状態を示しており、同図中 の一点鎖線で示す操作部分１８の位置は締め付け前の位置を示し、寸法Ｌだけね じ込んだことになる。また、この動作を各凹溝４内毎に行うことによって回路基 板１を複数並列に搭載できる。図４は、その途中の状態を示している。そして、 このようにして回路基板１を複数並列に搭載してなるシェルフ２では、各回路基 板１上の発熱素子（不図示）が発熱されると、この熱が冷却されている熱伝導性 冷却用ブロック３側に熱伝導して放熱される。Next, when the operating portion 18 of the tightening screw member 16 projecting toward the front side is rotated in the tightening direction (clockwise direction) with a screwdriver, the tightening screw member 16 is screwed in the direction of arrow X in FIG. Accordingly, the elastic member 8 is compressed. Then, the elastic member 8 is bent into a substantially V shape in the notch groove portion 10 in proportion to the compression amount, and both side surfaces 8a and 8b of the elastic member 8 are outside, that is, the circuit board 1 side. It deforms to a swelled state (in the direction of arrow Z in FIG. 1), and both side surfaces 8a and 8b press the circuit board 1 against the inner surfaces 4a and 4b of the groove 4, respectively. Then, the circuit board 1 is fixed in the groove 4 by this pressing force. FIG. 1 shows this state, and the position of the operating portion 18 shown by the alternate long and short dash line in the figure shows the position before tightening, and the dimension L has been screwed in. Further, by performing this operation for each groove 4, a plurality of circuit boards 1 can be mounted in parallel. FIG. 4 shows a state on the way. In the shelf 2 in which a plurality of circuit boards 1 are mounted in parallel in this way, when a heating element (not shown) on each circuit board 1 generates heat, this heat is cooled. Heat is conducted to the side of the cooling block 3 and is radiated.
【００２２】 これに対して、この回路基板１をメンテナンス等でシェルフ２より取り外す場 合は、ドライバーで操作部分１８を反対側に回して締め付けねじ部材１６の締め 付けを解く。すると、弾性部材８の圧縮量が減少して両側面８ａ，８ｂの膨らみ 量が減り、遂には回路基板１に対する押し付け力がなくなる。これにより、回路 基板１を前面側に簡単に抜き出し、再び挿入させることもできる。なお、この場 合、熱伝導性冷却用ブロック３に一度取り付けられた固定金具７は、その取り付 けたままの状態にして回路基板１の着脱を行うことができるものである。On the other hand, when the circuit board 1 is removed from the shelf 2 for maintenance or the like, the operation portion 18 is turned to the opposite side with a driver to release the tightening of the tightening screw member 16. Then, the amount of compression of the elastic member 8 decreases and the amount of swelling of both side surfaces 8a, 8b decreases, and finally the pressing force against the circuit board 1 disappears. Thereby, the circuit board 1 can be easily pulled out to the front side and inserted again. In this case, the fixing metal fitting 7 once attached to the heat conductive cooling block 3 can be attached / detached to / from the circuit board 1 in the state where the fixing metal fitting 7 is attached.
【００２３】 したがって、この実施例によるシェルフ構造では、回路基板１が着脱される前 面側に配設されている操作部分１８を回すことによって、弾性部材８の両側面８ ａ，８ｂの膨らみ量を調整し、回路基板１の固定および解除を簡単に行わせるこ とができる。しかも、弾性部材８の弾性変形で締め付けるので、この弾性部材８ の変形許容範囲内であれば、回路基板１の厚み寸法が異なったとしても、この寸 法誤差を吸収して締め付けることができることになり、汎用性が得られる。また 、固定金具７は一度取り付けておけば、次の回路基板１の着脱時には再度取り外 さずとも、操作部分１８を回すだけで操作することができる。Therefore, in the shelf structure according to this embodiment, the swelling amounts of the both side surfaces 8 a, 8 b of the elastic member 8 are turned by rotating the operation portion 18 arranged on the front surface side on which the circuit board 1 is attached and detached. Can be adjusted to easily fix and release the circuit board 1. In addition, since the elastic member 8 is tightened by elastic deformation, if the elastic member 8 is within the deformation allowable range, even if the thickness of the circuit board 1 is different, the size error can be absorbed and tightened. Therefore, versatility can be obtained. Further, once the fixing metal fitting 7 is attached, it can be operated only by turning the operation portion 18 without removing it again when the circuit board 1 is attached / detached next time.
【００２４】 なお、上記実施例では、凹溝４内に２枚の回路基板１を配置した場合について 説明したが、凹溝４内の片側にだけ回路基板１を設けた場合でも同様にして使用 できるものである。また、締め付けねじ部材１６の操作部分１８をドライバーで 操作する場合について説明したが、ドライバーに限ることなく、指などで回すよ うにしても勿論差し支えないものである。In the above embodiment, the case where the two circuit boards 1 are arranged in the groove 4 has been described, but the same operation is performed when the circuit board 1 is provided on only one side of the groove 4. It is possible. Further, the case where the operating portion 18 of the tightening screw member 16 is operated by the driver has been described, but it is not limited to the driver and may be rotated by a finger or the like as a matter of course.

以上説明したとおり、本考案に係る回路基板固定用シェルフ構造によれば、回 路基板の着脱操作面側に設けられている操作部分を介して締め付けねじ部材を回 転させて締め付けあるいは緩めると、この操作だけで回路基板を簡単、かつ確実 に着脱させることができる。また、締め付け操作する側と回路基板を着脱操作す る側を同じ面側にしてなるので着脱操作が簡単になる。これにより、作業性の向 上が期待できる。 さらに、弾性部材の弾性力を利用して押し付けているので、回路基板の厚み寸 法が多少異なっていても、この誤差は弾性変形によって吸収することができる。 これにより、固定金具の汎用性が得られ、この固定金具の少種多量生産が可能に なるので、固定金具のコストを下げて安価に提供でき、同時にシェルフ全体のコ ストを下げることができる等の効果が期待できる。 As described above, according to the shelf structure for fixing a circuit board according to the present invention, when the tightening screw member is rotated and tightened or loosened through the operation portion provided on the attachment / detachment operation surface side of the circuit board, The circuit board can be easily and surely attached and detached only by this operation. Also, since the side for tightening operation and the side for attaching / detaching the circuit board are on the same surface side, the attaching / detaching operation is simplified. This can be expected to improve workability. Further, since the elastic member is pressed using the elastic force, this error can be absorbed by elastic deformation even if the thickness of the circuit board is slightly different. As a result, the versatility of the fixing bracket can be obtained, and it becomes possible to mass-produce small quantities of this fixing bracket, so that the cost of the fixing bracket can be reduced and the cost can be provided at a low cost, and at the same time, the cost of the entire shelf can be lowered. The effect of can be expected.
