Description

本発明はプリント基板押さえ構造に関し、特に交換機や主装置などに装着されたプリント基板を確実に押さえて、プリント基板がコネクタと接触不良等の不具合を起こすのを極力防止するプリント基板押さえ構造に関する。   The present invention relates to a printed circuit board pressing structure, and more particularly to a printed circuit board pressing structure that reliably presses a printed circuit board mounted on an exchange or a main apparatus to prevent the printed circuit board from causing problems such as poor contact with a connector.

従来のプリント基板押さえ構造の一例として、例えば下記の特許文献１に記されているものがある。このプリント基板押さえ構造は、図５、図６に示すように、棚板Ａの正面開口部３０の左、右側部位３０Ｃ，３０Ｄにねじ孔３７を設け、また、左右両端にねじ挿入孔３８を有する長尺な押さえ部材３９を用意する。   As an example of a conventional printed circuit board pressing structure, there is one described in Patent Document 1 below, for example. As shown in FIGS. 5 and 6, this printed circuit board holding structure is provided with screw holes 37 in the left and right side portions 30C and 30D of the front opening 30 of the shelf board A, and screw insertion holes 38 at both left and right ends. A long pressing member 39 is prepared.

そして、棚板Ａの上下のガイドレール３５にプリント基板３２の上、下端部３２ａ、３２ｂを挿入し、棚板Ａの奥側に押し込んだ時点で、押さえ部材３９の左右端部のねじ挿入孔３８にねじ部材４０を挿入する。次いで、ねじ部材４０を前記ねじ孔３７にねじ込み、押さえ板３９でプリント基板３２を棚板Ａに固定する。   Then, when the upper and lower end portions 32a and 32b of the printed board 32 are inserted into the upper and lower guide rails 35 of the shelf board A and pushed into the rear side of the shelf board A, screw insertion holes at the left and right ends of the pressing member 39 are inserted. The screw member 40 is inserted into 38. Next, the screw member 40 is screwed into the screw hole 37, and the printed circuit board 32 is fixed to the shelf board A with the pressing plate 39.

特開２０００−３０７２７２号公報JP 2000-307272 A

しかしながら、前記した従来のプリント基板押さえ構造は、長尺な押さえ部材３９をその左右両端で２個のねじ部材４０により左右部位３０Ｃ，３０Ｄに固定するものであるので、ねじ止め部から離れた中央付近は、プリント基板を引き出そうとする力で押さえ部材３９がたわみ、押さえが不十分になるという課題があった。また、棚板Ａに大きな振動や衝撃が加わっても、棚板Ａの上下のガイドレールに挿入されているプリント基板が前方に動き、棚板Ａに固定されているコネクタとの接触不良が起きやすいという恐れがあった。また、長尺な押さえ部材３９をその左右両端で左、右側部位３０Ｃ，３０Ｄのねじ孔３７にねじ止めする際に、一端のねじ止め時に他端が落下するので、一方の手でこの落下を防ぎながら他方の手でねじ止めしなければならず、作業性が悪いという課題もあった。   However, since the above-described conventional printed circuit board pressing structure fixes the long pressing member 39 to the left and right portions 30C and 30D by the two screw members 40 at both left and right ends thereof, the center is separated from the screwing portion. In the vicinity, there is a problem that the pressing member 39 is bent by a force for pulling out the printed circuit board and the pressing becomes insufficient. Even if a large vibration or impact is applied to the shelf A, the printed circuit boards inserted in the upper and lower guide rails of the shelf A move forward, resulting in poor contact with the connector fixed to the shelf A. There was a fear that it was easy. Further, when the long pressing member 39 is screwed into the screw holes 37 of the left and right portions 30C and 30D at both left and right ends, the other end falls when the one end is screwed. There is also a problem that workability is poor because it must be screwed with the other hand while preventing.

本発明の目的は、前記した従来技術の課題を解決し、プリント基板実装筐体に実装されたプリント基板をより確実に押さえて、コネクタとの接触不良が起きるのを防止するプリント基板押さえ構造を提供することにある。また、他の目的は、作業性良くプリント基板実装筐体に取り付けることのできるプリント基板押さえ構造を提供することにある。   An object of the present invention is to provide a printed circuit board holding structure that solves the above-described problems of the prior art and more reliably presses a printed circuit board mounted on a printed circuit board mounting housing to prevent poor contact with a connector. It is to provide. Another object is to provide a printed circuit board pressing structure that can be attached to a printed circuit board mounting housing with good workability.

前記した目的を達成するために、本発明は、プリント基板実装筐体に実装されたプリント基板を押さえるプリント基板押さえ構造であって、プリント基板を支持する支持板と、前記プリント基板の実装位置と対向する位置において該支持板に穿孔されたスリットと、前記スリットを通って突出する平らな舌状の突起部と該平らな舌状の突起部の端部を前記スリットに対して折曲した屈曲突起部とを有するプリント基板押さえ部材とを具備し、前記平らな舌状の突起部および屈曲突起部は、前記プリント基板と対向する位置に位置合わせできるように前記スリット内をスライドでき、前記スリットは該屈曲突起部を挿通する形状のスリットを含み、前記平らな舌状の突起部および屈曲突起部により前記プリント基板を押さえ、前記屈曲突起部は前記プリント基板押さえ部材の落下を抑止するようにした点に特徴がある。 In order to achieve the above-described object, the present invention provides a printed circuit board pressing structure for pressing a printed circuit board mounted on a printed circuit board mounting housing, and includes a support plate that supports the printed circuit board, and a mounting position of the printed circuit board. A slit that is perforated in the support plate at an opposing position, a flat tongue-shaped protrusion protruding through the slit, and a bent portion in which the end of the flat tongue-shaped protrusion is bent with respect to the slit comprising a printed circuit board presser member having a protrusion, said flat tongue of projections and the bent protrusion can slide within the slit so as to be aligned with the position opposed to the printed circuit board, the slit includes a slit shape for inserting the the bend projections, said by flat tongue-like projection portion and bent projections holding the printed circuit board, the bent protrusion It is characterized in that so as to suppress the fall of the serial PCB pressing member.

また、前記屈曲突起部は、前記平らな舌状の突起部の端部を前記スリットに対して略９０°折曲したものである点に他の特徴がある。 Further, the bent projection has another feature in that the end of the flat tongue-like projection is bent by approximately 90 ° with respect to the slit .

本発明によれば、プリント基板と対向する位置において該プリント基板の支持板に穿孔されたスリットを通って突出する突起部によりプリント基板を押さえることができ、その突起部のたわみはスリットにより阻止されるので、プリント基板を従来のプリント基板押さえより確実に押さえることができるようになる。また、このため、プリント基板とコネクタとの接続がゆるむことがなくなり、接触不良が起きるのを防止できるようになる。また、信頼性の高いプリント基板押さえ構造を提供できるようになる。   According to the present invention, the printed circuit board can be pressed by the protrusion protruding through the slit perforated in the support board of the printed circuit board at a position facing the printed circuit board, and the deflection of the protrusion is prevented by the slit. Therefore, the printed circuit board can be pressed more securely than the conventional printed circuit board presser. For this reason, the connection between the printed circuit board and the connector is not loosened, and contact failure can be prevented from occurring. In addition, a highly reliable printed board holding structure can be provided.

さらに、屈曲突起部を屈曲スリットに差し込んで横方向にスライドさせることにより、プリント基板押さえが支持板に保持されて落下することがないので、２個のビスによるプリント基板押さえ部材の支持板への装着作業が簡単になり作業性が向上する。   Furthermore, by inserting the bending protrusion into the bending slit and sliding it in the lateral direction, the printed circuit board presser is held by the support plate and does not fall, so the printed board presser member is supported by the two screws on the support plate. Mounting work is simplified and workability is improved.

以下に、図面を参照して、本発明を詳細に説明する。図１は、本発明の一実施形態のプリント基板実装筐体に実装された複数のプリント基板の一部の斜視図である。   Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a part of a plurality of printed circuit boards mounted on a printed circuit board mounting housing according to an embodiment of the present invention.

図示されているように、プリント基板実装筐体のプリント基板の支持板、例えば上板および下板２のガイドレール３（上板および上側のガイドレールは不図示）に複数のプリント基板１が実装されている。下板２の左右に延びる前方壁２ａには、長尺のプリント基板押さえ部材４が配置され、その左右両端の起立部は取り付けビス５ａおよび５ｂで前記前方壁２ａに止められる。   As shown in the drawing, a plurality of printed circuit boards 1 are mounted on a support board of a printed circuit board of a printed circuit board mounting housing, for example, guide rails 3 on an upper board and a lower board 2 (upper and upper guide rails are not shown). Has been. A long printed board pressing member 4 is disposed on the front wall 2a extending to the left and right of the lower plate 2, and standing portions at both left and right ends thereof are fixed to the front wall 2a by mounting screws 5a and 5b.

前記プリント基板押さえ部材４の構造の一例を図２を参照して説明する。プリント基板押さえ部材４は好ましくは一枚の長尺の板材から一体成型されており、中央部に左右に延びる長尺溝１０が形成され、該溝１０の前側の左右の端部には起立部１１ａ、１１ｂが形成され、該溝１０の奥側には奥壁部１２が形成されている。そして、全体的には、ほぼ逆コ字状になっている。   An example of the structure of the printed board pressing member 4 will be described with reference to FIG. The printed circuit board pressing member 4 is preferably integrally formed from a single long plate material, and a long groove 10 extending in the left and right direction is formed in the center portion. Standing portions are formed at the left and right ends of the front side of the groove 10. 11 a and 11 b are formed, and a back wall portion 12 is formed on the back side of the groove 10. And overall, it is almost U-shaped.

前記溝１０は、下板２の前方壁２ａの厚みよりやや大きい幅を有し、該溝１０の前記起立部材１１ａ、１１ｂには、溝１０方向に長い長孔１３ａ、１３ｂが形成されている。また、一方の起立部材１１ａには、つまみ１６が形成されている。   The groove 10 has a width that is slightly larger than the thickness of the front wall 2a of the lower plate 2, and elongated members 13a and 13b that are long in the direction of the groove 10 are formed in the upright members 11a and 11b of the groove 10. . Moreover, the knob 16 is formed in one standing member 11a.

前記奥壁部１２の上辺には、プリント基板押さえ部材４を下板２の前方壁２ａに装着したときに、下板に設けられたスリットから突出する高さの複数の突起部１４と、屈曲突起部１５ａ、１５ｂが形成されている。突起部１４は平らな舌状の突起であるが、屈曲突起部１５ａ，１５ｂは、例えば９０°に折れ曲がった屈曲片であり、好ましくはプリント基板押さえ部材４の長さ方向の中央の両側に１個ずつ形成されている。各突起部１４、屈曲突起部１５ａ、１５ｂの間隔は、プリント基板実装筐体のプリント基板実装間隔、つまりガイドレール３間の間隔とほぼ等しくされている。   On the upper side of the back wall portion 12, when the printed board pressing member 4 is mounted on the front wall 2a of the lower plate 2, a plurality of protruding portions 14 projecting from slits provided in the lower plate, and bent Protrusions 15a and 15b are formed. The protrusion 14 is a flat tongue-shaped protrusion, but the bent protrusions 15a and 15b are bent pieces bent at, for example, 90 °, and preferably 1 on both sides of the center of the printed board pressing member 4 in the length direction. It is formed one by one. The intervals between the protrusions 14 and the bent protrusions 15a and 15b are substantially equal to the interval between the printed circuit boards mounted on the printed circuit board mounting housing, that is, the distance between the guide rails 3.

図３に、プリント基板押さえ部材４をプリント基板実装筐体に装着した時の要部の斜視図、図４に図３のＡ−Ａ’線断面図を示す。図３、図４において、図１、図２と同じ符号は同一または同等物を示す。   3 is a perspective view of a main part when the printed board holding member 4 is mounted on the printed board mounting housing, and FIG. 4 is a cross-sectional view taken along the line A-A ′ of FIG. 3 and 4, the same reference numerals as those in FIGS. 1 and 2 denote the same or equivalent components.

プリント基板実装筐体の下板２には、プリント基板押さえ部材４の突起部１４および屈曲突起部１５ａ、１５ｂを通すスリット２１および屈曲スリット２２ａ、２２ｂが前方壁２ａと平行に形成されている。これらのスリットは、突起部１４の幅および屈曲突起部１５ａ、１５ｂの突起部１４と同方向の幅より長い長さを有しており、該スリット２１および屈曲スリット２２ａ、２２ｂに突起部１４および屈曲突起部１５ａ、１５ｂが挿通された時には、プリント基板押さえ部材４が前記スリット方向に少しスライドできるようになっている。   The lower plate 2 of the printed circuit board mounting housing is formed with slits 21 and bent slits 22a and 22b through which the protrusions 14 and the bent protrusions 15a and 15b of the printed circuit board pressing member 4 pass in parallel to the front wall 2a. These slits have a length longer than the width of the protruding portion 14 and the width of the bent protruding portions 15a and 15b in the same direction as the protruding portion 14, and the protruding portion 14 and the bent slits 22a and 22b When the bent protrusions 15a and 15b are inserted, the printed circuit board pressing member 4 can be slightly slid in the slit direction.

さて、プリント基板押さえ部材４をプリント基板実装筐体に装着する時には、屈曲突起部１５ａ、１５ｂが屈曲スリット２２ａ、２２ｂと位置合わせされ、プリント基板押さえ部材４が下板２と密着するように持ち上げられる。これにより、突起部１４および屈曲突起部１５ａ、１５ｂがスリット２１および屈曲スリット２２ａ、２２ｂに挿通される。続いて、プリント基板押さえ部材４は前記スリット方向に少しスライドされ、下板２上に保持される。次いで、取り付けビス５ａ、５ｂを前記起立部材１１ａ、１１ｂの長孔１３ａ、１３ｂを通って下板２に途中まで螺入し、プリント基板押さえ部材４を下板２に仮着する。   Now, when mounting the printed circuit board pressing member 4 to the printed circuit board mounting housing, the bent protrusions 15 a and 15 b are aligned with the bent slits 22 a and 22 b, and the printed circuit board pressing member 4 is lifted so as to be in close contact with the lower plate 2. It is done. Thereby, the protrusion 14 and the bending protrusions 15a and 15b are inserted into the slit 21 and the bending slits 22a and 22b. Subsequently, the printed circuit board pressing member 4 is slightly slid in the slit direction and held on the lower plate 2. Next, the mounting screws 5 a and 5 b are screwed partway into the lower plate 2 through the long holes 13 a and 13 b of the upright members 11 a and 11 b, and the printed board pressing member 4 is temporarily attached to the lower plate 2.

なお、スリット２１及び屈曲スリット２２ａ、２２ｂに挿通された時には、ビス取付穴が長孔１３ａ、１３ｂから隠れた位置で嵌合させ、その後スライドさせることでビス取付穴が長孔１３ａ、１３ｂの位置と合うことで取り付けビス５ａ、５ｂで固着できる。このように構成することで、取り付けビス５ａ、５ｂで仮着した状態で長孔幅一杯にプリント基板押さえ部材４を左右にスライドさせた時にも、スリット部から誤って抜け落ちることを防止する構造である。   When the slit 21 and the bending slits 22a and 22b are inserted, the screw mounting holes are fitted in positions hidden from the long holes 13a and 13b, and then slid to slide the screw mounting holes to the positions of the long holes 13a and 13b. Can be fixed with the mounting screws 5a and 5b. With such a configuration, even when the printed board pressing member 4 is slid to the left and right to the full width of the long hole while temporarily attached with the mounting screws 5a and 5b, the structure prevents the slipping part from accidentally falling off. is there.

その後、つまみ１６を用いて、プリント基板押さえ部材４をスリット２１および屈曲スリット２２ａ、２２ｂに沿って再度スライドさせ、突起部１４および屈曲突起部１５ａ、１５ｂが、複数のプリント基板１の位置と対向するように位置合わせした所で、取り付けビス５ａ、５ｂをさらに螺入して、プリント基板押さえ部材４を下板２に固着する。なお、プリント基板押さえ部材４をスライドさせて長孔１３ａ、１３ｂの一方の端に当接させた位置で突起部１４をプリント基板１の位置と対向するようにすれば、ビス止めによる突起部１４をプリント基板１の位置に対向させるための微調整作業が必要なくなる。   Thereafter, the printed board pressing member 4 is slid again along the slit 21 and the bent slits 22a and 22b by using the knob 16, and the protrusion 14 and the bent protrusions 15a and 15b are opposed to the positions of the plurality of printed boards 1. Then, the mounting screws 5a and 5b are further screwed in so that the printed board pressing member 4 is fixed to the lower plate 2. It should be noted that if the protrusion 14 is opposed to the position of the printed circuit board 1 at a position where the printed circuit board pressing member 4 is slid and brought into contact with one end of the long holes 13a and 13b, the protrusion 14 by screwing is used. Need to be finely adjusted to face the position of the printed circuit board 1.

上記のことから明らかなように、プリント基板押さえ部材４は、前記仮着後は、屈曲突起部１５ａ、１５ｂと屈曲スリット２２ａ、２２ｂの働きにより、下板２から落下することがないので、取り付けビス５ａ、５ｂによるプリント基板押さえ部材４の下板２への固着作業が簡単になり作業性が向上する。   As is apparent from the above, the printed circuit board pressing member 4 is not attached after the temporary attachment due to the action of the bent protrusions 15a and 15b and the bent slits 22a and 22b. The work of fixing the printed board holding member 4 to the lower plate 2 with the screws 5a and 5b is simplified, and the workability is improved.

図１は、プリント基板１が実装された支持板（下板２）に、プリント基板押さえ部材４を仮着した斜視図を示している。取り付けビス５ａ、５ｂで仮止めされたプリント基板押さえ部材４は、図の左方向に少しスライドされて突起部１４および屈曲突起部１５ａ、１５ｂがプリント基板１と対向する位置に移動され、その位置で取り付けビス５ａ、５ｂを強く螺入して下板２に固着される。   FIG. 1 is a perspective view in which a printed board pressing member 4 is temporarily attached to a support plate (lower plate 2) on which the printed board 1 is mounted. The printed circuit board pressing member 4 temporarily fixed by the mounting screws 5a and 5b is slightly slid in the left direction in the drawing, and the protruding portion 14 and the bent protruding portions 15a and 15b are moved to a position facing the printed circuit board 1, and the position Then, the mounting screws 5a and 5b are firmly screwed and fixed to the lower plate 2.

以上のような構成を有する本実施形態では、図１から明らかなように、下板２のスリット２１，屈曲スリット２２ａ、２２ｂから突出したプリント基板押さえ部材４の突起部１４および屈曲突起部１５ａ、１５ｂが、個々のプリント基板１の前方への移動を強く押さえる。また、突起部１４および屈曲突起部１５ａ、１５ｂのたわみはスリット２１、屈曲スリット２２ａ、２２ｂにより阻止される。よって、該プリント基板１を引き出そうとする力が働いても、突起部１４および屈曲突起部１５ａ、１５ｂは強固にプリント基板１の移動を阻止する。また、プリント基板１に大きな振動や衝撃が加わっても、プリント基板実装筐体の上板および下板のガイドレールに挿入されているプリント基板が前方に動くのを阻止し、コネクタとの接触が緩んで接触不良が起きる等の不具合を防止することができる。   In the present embodiment having the above-described configuration, as is apparent from FIG. 1, the protrusion 14 and the bent protrusion 15 a of the printed board pressing member 4 protruding from the slit 21 and the bent slits 22 a and 22 b of the lower plate 2, 15b strongly suppresses the forward movement of each printed circuit board 1. Further, the deflection of the protrusion 14 and the bent protrusions 15a and 15b is prevented by the slit 21 and the bent slits 22a and 22b. Therefore, even if a force for pulling out the printed circuit board 1 is applied, the protrusion 14 and the bent protrusions 15a and 15b firmly prevent the printed circuit board 1 from moving. Further, even if a large vibration or impact is applied to the printed circuit board 1, the printed circuit board inserted into the guide rails of the upper and lower boards of the printed circuit board mounting housing is prevented from moving forward, and contact with the connector is prevented. Problems such as loose contact and poor contact can be prevented.

前記実施形態では、プリント基板押さえ構造をプリント基板実装筐体の下板に装着したが、その上板に装着することも可能である。また、前記実施形態では、縦方向に実装されたプリント基板の押さえ構造について説明したが、本発明はこれに限定されず、横方向に実装されたプリント基板の押さえにも適用できることは明らかである。この場合には、前記下板は、側板に配置されることは明らかである。   In the above embodiment, the printed board holding structure is attached to the lower plate of the printed board mounting housing, but it can also be attached to the upper plate. In the above-described embodiment, the pressing structure of the printed circuit board mounted in the vertical direction has been described. However, the present invention is not limited to this, and it is obvious that the present invention can also be applied to the pressing of the printed circuit board mounted in the horizontal direction. . In this case, it is clear that the lower plate is arranged on the side plate.

また、取り付けビス５ａ、５ｂは２カ所で説明したが、２カ所である必要はなく、任意の位置（例えば、中央付近）に１カ所あれば機能上は何の問題もなく対応できるものである。   Further, the mounting screws 5a and 5b have been described at two places. However, the mounting screws 5a and 5b do not have to be two places, and if there is one place at an arbitrary position (for example, near the center), the function can be handled without any problem. .
