Description

この発明は、コネクタを介して副基板を主基板上に脱着自在に装着した回路基板に関するものである。   The present invention relates to a circuit board in which a sub board is detachably mounted on a main board via a connector.

主基板上にコネクタを介して副基板を取り付けたものとして、（特許文献１）に示すものがある。   There exists a thing shown to (patent document 1) as what attached the subboard | substrate via the connector on the main board | substrate.

このものは、図４に示すような、モジュール基板（副基板）１を主基板２に固定板３を使って固定するようにしたもので、固定板３は副基板１を被う形状に形成されている。また、その副基板１を被う固定板３の四隅には、図４のような爪４が設けられており、前記爪４には、副基板１を支持するためのスペーサ部５が形成されている。   This is a module substrate (sub-board) 1 fixed to the main board 2 using a fixing plate 3 as shown in FIG. 4, and the fixing plate 3 is formed to cover the sub-board 1. Has been. Also, claws 4 as shown in FIG. 4 are provided at the four corners of the fixing plate 3 covering the sub-substrate 1, and spacer portions 5 for supporting the sub-substrate 1 are formed on the nails 4. ing.

このように構成される固定板３は、主基板２のコネクタ６と接続した副基板１の上から被せ、被せた固定板３の爪４を主基板２に設けたスリット７に嵌入する。その際、爪４のスペーサ部５は、副基板１と主基板２の間に嵌まるようにして、スリット７に嵌めた爪４の先端がスリット７を介して主基板２の裏面から突出するようにする。そして、主基板２の裏面から突出させた爪４の先端を折り曲げることにより、副基板１を主基板２に強固に固定するというものである。

Utility Model Registration No. 3108238

しかしながら、上記の固定法では、一度、副基板を主基板に取り付けてしまうと、爪を折り曲げているので、取り外しが困難である。さらに、取り外した固定板の爪は、一度折り曲げたものを伸ばすことになるので、強度が低下して、例えば落下などの衝撃で外れたり、その衝撃で外れた拍子にコネクタを破損したりすると困るので、再使用ができない問題があった。   However, in the above fixing method, once the sub-board is attached to the main board, it is difficult to remove it because the claws are bent. In addition, since the nail of the fixed plate that has been removed will be stretched once it has been bent, its strength will drop, and it will be a problem if it comes off due to an impact such as dropping, or the connector is damaged due to the beat removed by that impact. So there was a problem that could not be reused.

そのため、例えば、主基板の機能を変えるために、取り替えることが考えられるオプション基板などの副基板に使用するには適さない問題があった。   Therefore, for example, there is a problem that it is not suitable for use on a sub-board such as an option board that can be replaced in order to change the function of the main board.

そこで、この発明の課題は、まず、副基板の取り付け取り外しが容易に何度でも行なえるようにすることである。次に、落下などの衝撃を受けた場合でも副基板が外れないように取り付けられるようにすることにより、副基板が外れた際のコネクタの破損も起こし難くすることである。   Accordingly, an object of the present invention is to make it possible to easily attach and detach a sub-board any number of times. Next, it is made difficult to cause damage to the connector when the sub-board is removed by mounting the sub-board so that it does not come off even when subjected to an impact such as dropping.

上記の課題を解決するため、この発明では、副基板は、角型の基板の対向する両辺に係合部が形成され、一方、前記主基板には、副基板の対向する係合部と係合する係止片を基板上に設けた構成を採用したのである。   In order to solve the above problems, according to the present invention, the sub-board is formed with engaging portions on both sides of the square substrate facing each other, while the main substrate is engaged with the engaging portions of the sub-board facing each other. The structure which provided the locking piece to match | combine on the board | substrate was employ | adopted.

このような構成を採用することにより、副基板は、係止片との係合によって主基板に係止されているので、係合を解除すれば簡単に取外すことが可能である。また、係止片と係合させれば簡単に主基板に係止できるので、副基板の取り付け取り外しが何度でも行なえる。   By adopting such a configuration, the sub-board is locked to the main board by engagement with the locking piece, so that it can be easily removed by releasing the engagement. Moreover, since it can be easily locked to the main board by engaging with the locking piece, the sub-board can be attached and detached any number of times.

その際、副基板の係合部の一方を、辺の中央部分を突出させたものとし、他方を辺の中央部分を凹設したものとするとともに、主基板の係止片の一方に、前記副基板の係合部の一方に形成した突出部分を嵌めるスリットを形成し、上記主基板の係止片の他方を、副基板の他方の辺に形成した凹設部分に嵌合し、かつ、嵌合した他方の辺の上面に当接して係止する突部を前記係合片に設けた構成を採用したのである。   At that time, one of the engaging portions of the sub-board is made to project the central portion of the side, and the other is made to have the central portion of the side recessed, and one of the locking pieces of the main substrate is Forming a slit for fitting a protruding portion formed on one of the engaging portions of the sub-board, fitting the other of the locking pieces of the main board to a recessed portion formed on the other side of the sub-board, and A configuration is adopted in which the engaging piece is provided with a protrusion that abuts and engages with the upper surface of the other side that is fitted.

このような構成を採用することにより、副基板は、係合部の一方の突出部を、主基板の係止片のスリットに嵌め、他方の凹設を基板の係止片に嵌め、嵌めた他方の辺の上面を係止片の突部に当接して係止する。また、取り付けた副基板は、主基板の一方の係止片を、例えば曲げるなどして係止片の突出部との係合を解除すれば簡単に何度でも取り外しができる。   By adopting such a configuration, the sub-board is fitted by fitting one protruding portion of the engaging portion into the slit of the locking piece of the main board and the other concave portion into the locking piece of the substrate. The upper surface of the other side is brought into contact with the protrusion of the locking piece and locked. The attached sub-board can be easily removed any number of times by releasing one of the locking pieces of the main board by, for example, bending the engaging piece with the protruding portion of the locking piece.

また、このとき、主基板に弾性部材を介して副基板を取り付けた構成を採用することができる。   Moreover, the structure which attached the sub board | substrate via the elastic member to the main board | substrate at this time is employable.

このような構成を採用することにより、主基板と副基板の間に設けた弾性部材が、副基板を押し上げて副基板の係合部と主基板の係止片とを圧着して外れないようにするので、例えば、落下などの衝撃で外れないようにできるので、コネクタの破損も起こさないようにできる。   By adopting such a configuration, the elastic member provided between the main board and the sub board does not come off by pushing up the sub board and crimping the engaging part of the sub board and the locking piece of the main board. Therefore, for example, it can be prevented from coming off by an impact such as dropping, so that the connector can be prevented from being damaged.

この発明は、以上のように構成したことにより、副基板の取り付け取り外しが容易にできる。また、主基板に取り付けた副基板は、例えば、落下などの衝撃を受けても外れないので、コネクタの破損も起こし難くい。   According to the present invention configured as described above, the sub-board can be easily attached and detached. Further, the sub-board attached to the main board does not come off even when subjected to an impact such as dropping, so that the connector is hardly damaged.

以下、この形態の実施の形態を図面に基づいて説明する。図１及び図２に示すように、この形態の回路基板は、基板上にコネクタ６のヘッダー６ａを設けた副基板（オプション基板）１と、前記基板上にコネクタ６のソケット６ｂを設けた主基板２との間に、弾性部材８を設けた構成となっている。   Hereinafter, embodiments of this embodiment will be described with reference to the drawings. As shown in FIG. 1 and FIG. 2, the circuit board of this embodiment has a sub board (option board) 1 in which the header 6a of the connector 6 is provided on the board, and a main board in which the socket 6b of the connector 6 is provided on the board. An elastic member 8 is provided between the substrate 2 and the substrate 2.

前記副基板１は、この形態の場合、長方形のものを採用しており、この長方形の基板の表面に電子部品１６を装着し、裏面には前記ヘッダー６ａを装着した構成としている。さらに、この長方形の基板の対向する両方の辺（長手方向）に係合部９ａ、９ｂを形成し、この係合部９ａ、９ｂの一方９ａには、辺の中央部分を突出させた突起部１０を形成してある。また、係合部９ａ、９ｂの他方９ｂは中央部分を凹設した構造となっている。   In this embodiment, the sub-board 1 is rectangular, and the electronic component 16 is mounted on the front surface of the rectangular substrate, and the header 6a is mounted on the back surface. Further, engaging portions 9a and 9b are formed on both opposing sides (longitudinal direction) of the rectangular substrate, and one of the engaging portions 9a and 9b has a protruding portion in which the central portion of the side protrudes. 10 is formed. Further, the other 9b of the engaging portions 9a and 9b has a structure in which the central portion is recessed.

一方、主基板２は、基板上に、副基板１の係合部９ａ、９ｂと係合する係止片１１ａ、１１ｂを設けた構造となっている。前記係止片１１ａ、１１ｂは、この形態の場合、図２に示すように、ほぼ、長方形のフレーム（枠体）１１の長手方向の対向する片で、前記片１１ａ、１１ｂは残りの片１１ｃ、１１ｄより高くしてある。また、フレーム１１から立ち上げた各片１１ａ〜１１ｄの上部は四隅で分離されおり、この各片１１ａ〜１１ｄで形成される開口１２には、後述する弾性部材８が収容できるようにしてある。   On the other hand, the main board 2 has a structure in which locking pieces 11a and 11b that engage with the engaging portions 9a and 9b of the sub board 1 are provided on the board. In the case of this embodiment, the locking pieces 11a and 11b are substantially opposing pieces in the longitudinal direction of a rectangular frame (frame body) 11, as shown in FIG. 2, and the pieces 11a and 11b are the remaining pieces 11c. , 11d. Further, the upper portions of the pieces 11a to 11d raised from the frame 11 are separated at the four corners, and an elastic member 8 described later can be accommodated in the opening 12 formed by the pieces 11a to 11d.

なお、この形態では、フレーム１１は、ステンレス材にＮｉメッキを施したものとしたが、これに限定されるものではなく、所要の強度と弾性があるものであれば、樹脂やステンレス以外の金属で形成してもよい。   In this embodiment, the frame 11 is obtained by applying Ni plating to a stainless material. However, the present invention is not limited to this, and any metal other than resin or stainless steel can be used as long as it has a required strength and elasticity. May be formed.

この係止片１１ａ、１１ｂの一方１１ａにはスリット１３ａを形成して、前記スリット１３ａに副基板１の係合部９ａ（一方）の一方に形成した突起部１０が嵌まるようにしてある。具体的には、スリット１３ａを設けて、そのスリット１３ａの上方をフレーム１１の係止片１１ａを外側へ反らせるように少し折り曲げてある。この外側へ反らせたスリット１３ａの上方は、副基板１を取り付ける際には、副基板１の突起部（係合部）１０のスリット１３ａへの導入を助け、また、副基板１を取り外す際には、前記部分に指を掛けて、外側へ反らせることができるようにしてある。   A slit 13a is formed in one of the locking pieces 11a and 11b, and a protrusion 10 formed on one of the engaging portions 9a (one) of the sub-board 1 is fitted into the slit 13a. Specifically, the slit 13a is provided, and the upper portion of the slit 13a is slightly bent so that the locking piece 11a of the frame 11 is bent outward. The upper side of the slit 13a bent outward is to assist the introduction of the protrusion (engagement portion) 10 of the sub-board 1 into the slit 13a when the sub-board 1 is attached, and when the sub-board 1 is removed. Can be bent outward by putting a finger on the part.

また、係止片１１ａ、１１ｂの他方１１ｂは、副基板１の係合部９ｂの凹設部分と嵌合するように寸法が設定されている。具体的には、係止片１１ｂの上部を副基板１の凹設部分に合わせて形成してある。また、この、係止片１１ｂにスリット１３ｂを設け、そのスリット１３ｂの上方を中央部分がフレーム１１の内側へ突出するように折り曲げて突部１４を形成して、係止片１１ｂに嵌合した副基板１の係合部９ｂ（上面）に押さえとして当接するようにしてある。   Further, the other 11b of the locking pieces 11a and 11b is dimensioned so as to be fitted to the recessed portion of the engaging portion 9b of the sub-board 1. Specifically, the upper portion of the locking piece 11b is formed to match the recessed portion of the sub-substrate 1. In addition, a slit 13b is provided in the locking piece 11b, and a projection 14 is formed by bending the upper part of the slit 13b so that the central portion protrudes to the inside of the frame 11, and is fitted to the locking piece 11b. The sub-board 1 is in contact with the engaging portion 9b (upper surface) as a presser.

なお、このようにスリットを利用して突部を設けるようにしたことにより、両方の係止片１１ａ、１１ｂとも同様のスリット加工を行なえば折り曲げ加工だけで、対処できるので効率がよい。   Since the protrusions are provided by using the slits in this way, both the locking pieces 11a and 11b can be dealt with only by bending if the same slit processing is performed, which is efficient.

弾性部材８は、例えば、スポンジゴム、ゴム、スポンジなどの絶縁性の良い弾性体を、ここでは、図１のように、枠型に形成して、フレーム１１の内周に収容できるようにしたものである。また、その弾性部材８の厚みは、例えば副基板１を取り付けた際に支持できる厚みとし、取り付けた副基板１に少し上向きの弾制圧を発生できる程度の厚みのものを試作などして適宜決めればよい。   As the elastic member 8, for example, an elastic body having good insulation such as sponge rubber, rubber, or sponge is formed in a frame shape as shown in FIG. 1 so that it can be accommodated in the inner periphery of the frame 11. Is. The thickness of the elastic member 8 is determined as appropriate by, for example, making it a thickness that can be supported when the sub-board 1 is attached, and making a prototype with a thickness that can generate a slight upward pressure suppression on the attached sub-board 1. That's fine.

なお、この形態では、弾性部材８を枠型にしたが、これに限定されるものではなく、必要な弾性圧が得られるなら、例えば、フレーム１１の四隅に設けるだけでも良く、どのような形状のものでも良い。   In this embodiment, the elastic member 8 has a frame shape. However, the elastic member 8 is not limited to this. For example, the elastic member 8 may be provided at the four corners of the frame 11 as long as necessary elastic pressure can be obtained. May be good.

この形態は、上記のように構成されており、次に、主基板２への副基板１の取り付け方法を説明する。   This embodiment is configured as described above. Next, a method for attaching the sub board 1 to the main board 2 will be described.

まず、主基板２に副基板１を取り付ける場合は、フレーム１１内に弾性部材８を取り付け、図３（ａ）に示すように、副基板１の凹設された係合部９ｂがフレーム１１の係止片１１ｂの突部１４の下部と接するようにスリット１３ｂへ押入れる。   First, when the sub-board 1 is attached to the main board 2, the elastic member 8 is attached in the frame 11, and as shown in FIG. It pushes into the slit 13b so that it may contact the lower part of the protrusion 14 of the latching piece 11b.

すなわち、突部１４と弾性部材８との間に係合部９ｂを押入れて係止片１１ｂに嵌入し、突部１４にその上面を引っ掛ける。この状態で、前記突部１４と係合部９ｂの当接した点を軸にして副基板１を矢印のように回転させながら、副基板１の突起部１０の形成された係合部９ａをフレーム１１の係止片１１ａへ当接し押し込む。すると、フレーム１１の係止片１１ａが外向きに反って押し広がるので、副基板１の突起部１０が図３（ｂ）のように、前記係止片１１ａのスリット１３ａに嵌まる。同時に、コネクタ６の副基板１のヘッダー６ａが主基板２のソケット６ｂに嵌まる。また、こうして副基板１の突起部１０がフレーム１１の係止片１１ａのスリット１３ａに嵌まると、反っていた係止片１１ａが元に戻るので、副基板１が外れなくなる。このとき、押圧で縮小していた弾性部材８の反発力でもって副基板１は押し上げられるので、副基板１の係合部９ａ、９ｂは係合片１１ａと１１ｂの突部１４とスリット１３の上部に押し付けられ完全に固定される。そのため、例えば、回路基板が落下による衝撃を受けても副基板１は外れることはない。また、衝撃を受けても外れないので、両基板１、２を接続するコネクタ６が破損することもない。   That is, the engaging portion 9b is pushed in between the protruding portion 14 and the elastic member 8 to be fitted into the locking piece 11b, and the upper surface of the protruding portion 14 is hooked. In this state, while rotating the sub-board 1 as indicated by an arrow about the point where the protrusion 14 and the engaging portion 9b are in contact with each other, the engaging portion 9a formed with the protrusion 10 of the sub-board 1 is moved. The frame 11 is brought into contact with and pushed into the locking piece 11a. Then, the locking piece 11a of the frame 11 is pushed outward and spreads, so that the protrusion 10 of the sub-board 1 fits into the slit 13a of the locking piece 11a as shown in FIG. At the same time, the header 6 a of the sub-board 1 of the connector 6 is fitted into the socket 6 b of the main board 2. Further, when the protruding portion 10 of the sub-board 1 is thus fitted into the slit 13a of the locking piece 11a of the frame 11, the warped locking piece 11a returns to its original state, so that the sub-board 1 cannot be detached. At this time, since the sub-board 1 is pushed up by the repulsive force of the elastic member 8 reduced by the pressing, the engaging portions 9a and 9b of the sub-board 1 are formed by the protrusions 14 of the engaging pieces 11a and 11b and the slits 13 respectively. Pressed to the top and completely fixed. Therefore, for example, even if the circuit board receives an impact caused by dropping, the sub-board 1 does not come off. Further, since the connector 6 is not detached even when subjected to an impact, the connector 6 that connects both the boards 1 and 2 is not damaged.

ちなみに、副基板１の突起部１０を形成した係合部９ａ、９ｂの両端１５を図２のように突出させて、フレーム１１の係止片１１ａ、１１ｂの左右に設けた切欠きと嵌合するようにしているので、両者が係合して副基板１、２が捩れなどを起こすことを防止している。   By the way, both ends 15 of the engaging portions 9a and 9b on which the protruding portion 10 of the sub-board 1 is formed protrude as shown in FIG. 2 and are fitted with notches provided on the left and right of the locking pieces 11a and 11b of the frame 11. Therefore, the sub-boards 1 and 2 are prevented from being twisted due to their engagement.

一方、図３（ｂ）のように、主基板２に取り付けた副基板１を外す場合は、スリット１３ａを形成したフレーム１１の係止片１１ａの反った上部に指を当て、外向きに反らせて、スリット１３ａから副基板１の突起部１０を外すと、副基板１は、図３（ａ）の矢印と逆方向へ弾性部材８に押されて自動的に外れるため、外れた副基板１を引き抜いて他方の係止片１１ｂ及び係止片１１ｂの突部１４との係合を解除すれば簡単に取り外せる。このように、取り外しも簡単に行なえる。   On the other hand, as shown in FIG. 3B, when the sub-board 1 attached to the main board 2 is removed, a finger is applied to the warped upper portion of the locking piece 11a of the frame 11 in which the slit 13a is formed, and the board is bent outward. When the protrusion 10 of the sub-board 1 is removed from the slit 13a, the sub-board 1 is automatically removed by being pushed by the elastic member 8 in the direction opposite to the arrow in FIG. Can be easily removed by pulling out and releasing the engagement between the other locking piece 11b and the protrusion 14 of the locking piece 11b. In this way, it can be easily removed.

なお、この形態では、副基板１にヘッダー６ａを設け、主基板２にソケット６ｂを設けたものについて述べたが、これに限定されるものでない。副基板１にソケット６ｂを設け、主基板２にヘッダー６ａを設けたものについても同様である。   In this embodiment, the header 6a is provided on the sub-board 1 and the socket 6b is provided on the main board 2. However, the present invention is not limited to this. The same applies to the sub board 1 provided with the socket 6b and the main board 2 provided with the header 6a.

このように、この回路基板は、シンプルな構造で強度も十分あるので、副基板を主基板にコネクタを介して脱着自在に取り付ける構造の回路基板に適用できる。   Thus, since this circuit board has a simple structure and sufficient strength, it can be applied to a circuit board having a structure in which the sub board is detachably attached to the main board via the connector.
