本発明は、コンデンサ及び電子部品を実装してある回路素子モジュールをケース上に実装してある回路装置に関するものである。   The present invention relates to a circuit device in which a circuit element module on which a capacitor and an electronic component are mounted is mounted on a case.

本願発明者は、図３及び図４に示すように、回路素子が実装された回路基板を収容するケース１と、前記回路基板の回路に電気的に接続されるコンデンサ２と、このコンデンサ２を覆い、ケース１と係合するカバー３と、カバー３の開口部に備え、このカバー３内のコンデンサ２を固定するグロメット４とを備えてあり、カバー３に覆われたコンデンサ２の一部をケース１の壁部に形成した開口部から突出させて配置していることを特徴とするコンデンサを備える回路装置を発明した（特許文献１参照）。   As shown in FIGS. 3 and 4, the inventor of the present application includes a case 1 that accommodates a circuit board on which circuit elements are mounted, a capacitor 2 that is electrically connected to the circuit of the circuit board, and the capacitor 2. A cover 3 that covers and engages the case 1 and a grommet 4 that is provided at the opening of the cover 3 and that fixes the capacitor 2 in the cover 3 are provided. A part of the capacitor 2 covered by the cover 3 is provided. Invented a circuit device including a capacitor, characterized in that the circuit device is arranged so as to protrude from an opening formed in a wall portion of the case 1 (see Patent Document 1).

この回路装置は、複数のコンデンサ２を設け、各々のコンデンサ２のリード線２１を接続用基板２３に固定してある。また、コンデンサ２に臨む一方の面と反対の他方の面には各々２つの接続端子２２がハンダ等で取り付けられている。また、コンデンサ２とカバー３との間に防爆弁が作動可能な隙間３２を有する。なお、図３は従来例の斜視図、図４は図３図示従来例にモールド充填した状態を示す図３図示Ｂ−Ｂ断面図である。
特願２００６−１０４０６３ In this circuit device, a plurality of capacitors 2 are provided, and lead wires 21 of the respective capacitors 2 are fixed to a connection substrate 23. In addition, two connection terminals 22 are attached to the other surface opposite to the one surface facing the capacitor 2 with solder or the like.

Japanese Patent Application No. 2006-104063

しかし、上記コンデンサを備える回路装置は、ケース１に組み込みモールド樹脂５をカバー３と接する面まで満たして硬化させた場合において、コンデンサ２とカバー３との間に有する防爆弁が作動可能な隙間３２だけでは、コンデンサ２の防爆弁作動時にカバー３の内部を減圧しきれず、カバー３自体が爆発する恐れがあった。   However, the circuit device including the capacitor has a gap 32 in which the explosion-proof valve between the capacitor 2 and the cover 3 can operate when the mold resin 5 is filled in the case 1 and cured to fill the surface in contact with the cover 3. However, when the explosion-proof valve of the capacitor 2 is operated, the inside of the cover 3 cannot be fully decompressed, and the cover 3 itself may explode.

そこで、カバー３自体の爆発を回避するため、従来の構造においては、図４に示すように、コンデンサの一部の周縁をモールド樹脂５で覆った上で、グロメット２の一部が露出する状態になるまで、モールド樹脂５をカバー充填していた。しかし、この場合、モールド樹脂５がカバー３開口面全体を覆わないように、モールド樹脂５の量を確認する作業が必要となり、作業性が悪いという問題が生じた。   Therefore, in order to avoid the explosion of the cover 3 itself, in the conventional structure, as shown in FIG. 4, a part of the grommet 2 is exposed after the periphery of a part of the capacitor is covered with the mold resin 5. Until then, the mold resin 5 was filled with a cover. However, in this case, an operation for confirming the amount of the mold resin 5 is required so that the mold resin 5 does not cover the entire opening surface of the cover 3, resulting in a problem of poor workability.

本発明は、上記問題に鑑みてなされたものであり、モールド樹脂を充填した際に、コンデンサを収容するカバー内を減圧することができるコンデンサを備えた回路装置を提供する。   This invention is made | formed in view of the said problem, and provides a circuit apparatus provided with the capacitor | condenser which can depressurize the inside of the cover which accommodates a capacitor | condenser when it fills with mold resin.

上記課題を解決するために、本発明に係るコンデンサを備える回路装置は、回路素子が実装された回路基板を収容するケースと、前記回路基板の回路に電気的に接続されるコンデンサと、前記コンデンサを覆い、前記ケースと係合するカバーと、前記カバーの開口部に備え、前記カバー内の前記コンデンサを固定するグロメットとを備え、前記カバーに覆われたコンデンサの一部を前記ケースの壁部に形成した開口部から突出させて配置してあり、前記カバーの開口部周縁の一部を切欠し、この切欠部から前記グロメットの一部を露出させ、前記カバー内の圧力がカバー防爆限界値未満の所定値を超えると、前記グロメットと前記カバーとの間に隙間を有するように構成してあることを特徴とする。   In order to solve the above problems, a circuit device including a capacitor according to the present invention includes a case for housing a circuit board on which a circuit element is mounted, a capacitor electrically connected to a circuit of the circuit board, and the capacitor A cover that engages with the case, and a grommet that is provided in an opening of the cover and that fixes the capacitor in the cover, and a part of the capacitor covered by the cover is part of the wall of the case A part of the periphery of the opening of the cover is cut out, a part of the grommet is exposed from the notch, and the pressure in the cover is the cover explosion-proof limit value. If it exceeds a predetermined value less than, a gap is formed between the grommet and the cover.

前記露出したグロメットと前記カバーとを接着して、前記コンデンサを固定してあることを特徴とする。   The capacitor is fixed by adhering the exposed grommet and the cover.

本発明によれば、ケースに組み込みモールド樹脂をカバーと接する面まで満たして硬化させた場合において、グロメットの一部を前記カバー開口部周縁に形成した切欠部から露出させ、前記カバー内の圧力がカバー防爆限界値未満の所定値を超えると、前記グロメットと前記カバーとの間に隙間を有するように構成してあることにより、コンデンサの防爆弁作動時に前記カバー内に充満するガスがグロメットとカバーとの間に出来る隙間から外部へ抜けて、カバー内が減圧され、その結果、コンデンサカバー自体が爆発することを防止することができる効果である。   According to the present invention, when the embedded mold resin is filled in the case up to the surface in contact with the cover and cured, a part of the grommet is exposed from the notch formed at the periphery of the cover opening, and the pressure in the cover is reduced. When a predetermined value that is less than the cover explosion-proof limit value is exceeded, a gap is formed between the grommet and the cover, so that the gas that fills the cover when the explosion-proof valve of the capacitor is operated is filled with the grommet and the cover. This is an effect that prevents the capacitor cover itself from exploding because the inside of the cover is depressurized through the gap formed between the capacitor cover and the inside of the cover.

また、グロメットの一部をカバー開口部周縁に形成した切欠部から露出させてあるため、カバー開口面全体をモールド樹脂で覆っても、常にグロメットとカバーとの間に隙間を有することができる状態になるため、モールド樹脂の量を確認する作業を必要とせず、作業性が良い。   In addition, since a part of the grommet is exposed from the notch formed on the periphery of the cover opening, even when the entire cover opening surface is covered with mold resin, there can always be a gap between the grommet and the cover. Therefore, the work of checking the amount of the mold resin is not required, and the workability is good.

前記カバーと前記グロメットとを接着してあることにより、カバー内の圧力がカバー防爆限界値未満の所定値を超えた段階で、グロメットとカバーとの間に、容易に隙間を有することができ、確実にカバー内を減圧することができる効果がある。   By adhering the cover and the grommet, it is possible to easily have a gap between the grommet and the cover when the pressure in the cover exceeds a predetermined value less than the cover explosion-proof limit value, There is an effect that the inside of the cover can be surely decompressed.

発明を実施するための最良の形態に係る図を図１及び図２に示す。なお、図１は本願発明に係る一実施例における斜視図、図２は図１図示実施例にモールド充填した状態の図１図示Ａ−Ａ断面図である。   FIGS. 1 and 2 show the best mode for carrying out the invention. FIG. 1 is a perspective view of an embodiment according to the present invention, and FIG. 2 is a cross-sectional view taken along line AA in FIG.

本実施形態に係る回路装置はケース１を備えてある。このケース１は回路素子が実装された回路基板を収容するものである。なお、本実施例に係る回路装置において回路基板は図示されていないが、回路基板の構成については限定されない。本実施例に係るケース１は壁部の一部を開放してあり、この開放部に、回路基板の回路に電気的に接続されるコンデンサ２を複数並列に装着できるようにしてある。なお、本実施例に係る回路装置においてコンデンサ２と回路基板との接続手段についても限定されない。   The circuit device according to this embodiment includes a case 1. The case 1 accommodates a circuit board on which circuit elements are mounted. In addition, although the circuit board is not illustrated in the circuit device according to the present embodiment, the configuration of the circuit board is not limited. The case 1 according to the present embodiment has a part of the wall portion opened, and a plurality of capacitors 2 electrically connected to the circuit of the circuit board can be mounted in parallel in the open portion. In the circuit device according to the present embodiment, the connection means between the capacitor 2 and the circuit board is not limited.

この回路装置は、複数のコンデンサ２を設けてある。また、コンデンサ２に臨む一方の面と反対の他方の面には各々２つの接続端子２２がハンダ等で取り付けられている。   This circuit device is provided with a plurality of capacitors 2. In addition, two connection terminals 22 are attached to the other surface opposite to the one surface facing the capacitor 2 with solder or the like.

本実施例に係るコンデンサ２は防爆弁を有する面を短手方向にしてあり、コンデンサ２の長手方向と回路基板は平行に配置されるように構成してある。コンデンサ２の防爆弁から覆うようにカバー３を設けてある。本実施例に係るカバー３は一端部が挿入口の外縁に連なり、ここからコンデンサ２の軸線と略平行に延びている。その外形は円筒形状の収容部を３つ連ねた形状を有する。各収容部はコンデンサ２を収納可能な大きさを有し、挿入口の他端は閉鎖してある。なお、本実施例に係るカバー３は収容部を３つ連ねた形状を有するが、例えばカバー３一つに対して収容可能なコンデンサ１が一つであってもよい。このカバー３はケース１と係合させ、カバー３がケース１と係合することにより、カバー３がケース１の外側に向けて延設されるように構成してある。   The capacitor 2 according to this embodiment is configured such that the surface having the explosion-proof valve is in the short direction, and the longitudinal direction of the capacitor 2 and the circuit board are arranged in parallel. A cover 3 is provided so as to cover the explosion-proof valve of the capacitor 2. One end of the cover 3 according to the present embodiment is connected to the outer edge of the insertion port, and extends substantially parallel to the axis of the capacitor 2 from here. The outer shape has a shape in which three cylindrical accommodating portions are connected. Each accommodating portion has a size capable of accommodating the capacitor 2, and the other end of the insertion port is closed. The cover 3 according to the present embodiment has a shape in which three accommodating portions are connected. For example, one capacitor 1 that can be accommodated in one cover 3 may be provided. The cover 3 is engaged with the case 1, and the cover 3 is configured to extend toward the outside of the case 1 when the cover 3 is engaged with the case 1.

カバー３はコンデンサ２のリード線２１並びに接続端子２２の取り付け面が開口するように構成してある。また、カバー３の開口部周縁の一部に切欠部３１を形成し、この切欠部３１から後述するグロメット４の一部を露出させるように構成してある。カバー３内にコンデンサ２を支持固定するグロメット４を備えてある。このグロメット４はカバー３とコンデンサ２との間に介在してコンデンサ２を支持固定する部材であるが、本発明に係るグロメット４の一部は前述するように、カバー３から露出するように構成してあり、露出したグロメット４の周縁とカバー３とを接着して、コンデンサ２を固定してある。   The cover 3 is configured such that the attachment surface of the lead wire 21 and the connection terminal 22 of the capacitor 2 is opened. Further, a notch 31 is formed in a part of the periphery of the opening of the cover 3, and a part of the grommet 4 described later is exposed from the notch 31. A grommet 4 for supporting and fixing the capacitor 2 is provided in the cover 3. The grommet 4 is a member that is interposed between the cover 3 and the capacitor 2 and supports and fixes the capacitor 2. However, a part of the grommet 4 according to the present invention is configured to be exposed from the cover 3 as described above. The capacitor 2 is fixed by adhering the exposed peripheral edge of the grommet 4 and the cover 3.

なお、本実施例においては、グロメット４とカバー３との接着は、カバー３内の圧力がカバー防爆限界値未満の所定値を超えると、グロメット４とカバー３との間に隙間を有する程度に接着してある。本実施例ではグロメット４とカバー３との間を接着してあるが、グロメット４とカバー３との接着は、カバー３内の圧力がカバー防爆限界値未満の所定値を超えると、グロメット４とカバー３との間に隙間を有する程度に何らかの手段により液密状態にしてあればよい。また、露出したグロメット４の周縁とカバー３との間のみ接着しても良く、グロメット４がカバー３と接する面全てに接着しても良い。   In this embodiment, the grommet 4 and the cover 3 are bonded to such an extent that there is a gap between the grommet 4 and the cover 3 when the pressure in the cover 3 exceeds a predetermined value less than the cover explosion-proof limit value. Bonded. In this embodiment, the grommet 4 and the cover 3 are bonded together. However, the grommet 4 and the cover 3 are bonded to each other when the pressure in the cover 3 exceeds a predetermined value less than the cover explosion-proof limit value. What is necessary is just to make it a liquid-tight state by some means to such an extent that it has a clearance gap with the cover 3. FIG. Further, it may be adhered only between the exposed periphery of the grommet 4 and the cover 3, or the grommet 4 may be adhered to all the surfaces in contact with the cover 3.

次に、本実施例に係る製造方法について説明する。先ず、コンデンサ２の防爆弁を有する面からグロメット４の挿入孔に挿入する。この際、グロメット４がコンデンサ２の窪み近傍に位置するように挿入する。このときコンデンサ２とグロメット４とは液密な状態となる。   Next, the manufacturing method according to the present embodiment will be described. First, the capacitor 2 is inserted into the insertion hole of the grommet 4 from the surface having the explosion-proof valve. At this time, the grommet 4 is inserted so as to be positioned in the vicinity of the recess of the capacitor 2. At this time, the capacitor 2 and the grommet 4 are in a liquid-tight state.

グロメット４を嵌め合わせたコンデンサ２にカバー３を覆う。この際、カバー３とコンデンサ２との間に防爆弁が作動可能な隙間３２を有するように、コンデンサ２にカバー３を覆うとともに、グロメット４の開放面とカバー３の開放面とがほぼ同一面になるように覆う。これにより、グロメット４と液密な状態にすることができる。   The cover 3 is covered with the capacitor 2 fitted with the grommet 4. At this time, the cover 2 is covered with the capacitor 2 so that the explosion-proof valve can be operated between the cover 3 and the capacitor 2, and the open surface of the grommet 4 and the open surface of the cover 3 are substantially the same surface. Cover to be. Thereby, it can be set as a liquid-tight state with the grommet 4. FIG.

本発明では、カバー３の開口部周縁の一部に切欠部３１を形成し、この切欠部３１からグロメット４の一部が露出する。そのため、カバー３の切欠部３１の周縁においては、グロメット４とカバー３との間に隙間ができる。これを防止するため、本実施例においては、グロメット４とカバー３との間を、カバー３内の圧力がカバー防爆限界値未満の所定値を超えると、グロメット４とカバー３との間に隙間を有する程度に接着する。   In the present invention, the notch 31 is formed in a part of the periphery of the opening of the cover 3, and a part of the grommet 4 is exposed from the notch 31. Therefore, a gap is formed between the grommet 4 and the cover 3 at the periphery of the notch 31 of the cover 3. In order to prevent this, in this embodiment, when the pressure in the cover 3 exceeds a predetermined value that is less than the cover explosion-proof limit value, a gap is formed between the grommet 4 and the cover 3. Adhere to the extent that it has.

コンデンサ２を被せたカバー３をケース１の係合部に係合し、予め電気電子部品を実装した回路基板を、ケース１に収容する。コンデンサ２の接続端子２２と回路基板とをハンダ等で取り付けて、コンデンサ２と回路基板とを電気的に接続する。さらに、図２に示すように、ケース１内に露出したグロメット４の側面と接するまでモールド樹脂５を充填する。このとき接続端子２２などの電気接点やリード線２１をモールド樹脂５に浸漬させる。モールド樹脂５を硬化させると回路装置が完成する。   The cover 3 covered with the capacitor 2 is engaged with the engaging portion of the case 1, and a circuit board on which electrical and electronic components are mounted in advance is accommodated in the case 1. The connection terminal 22 of the capacitor 2 and the circuit board are attached with solder or the like, and the capacitor 2 and the circuit board are electrically connected. Further, as shown in FIG. 2, the mold resin 5 is filled until it contacts the side surface of the grommet 4 exposed in the case 1. At this time, the electrical contacts such as the connection terminals 22 and the lead wires 21 are immersed in the mold resin 5. When the mold resin 5 is cured, the circuit device is completed.

以上のような構成により、以下のような作用をする。先ず、通常は、コンデンサ２とグロメット４とはグロメット４の作用により液密の状態にある。また、グロメット４とカバー３とはグロメット４の作用と、グロメット４の露出部４１におけるグロメット４とカバー３との接着の作用とにより液密の状態にある。   With the above configuration, the following operation is performed. First, the capacitor 2 and the grommet 4 are normally in a liquid-tight state due to the action of the grommet 4. Further, the grommet 4 and the cover 3 are in a liquid-tight state due to the action of the grommet 4 and the action of adhesion between the grommet 4 and the cover 3 in the exposed portion 41 of the grommet 4.

続いて、モールド樹脂を充填するなどにより、カバー３内の圧力がカバー防爆限界値未満の所定値を超えると、グロメット４の露出部４１におけるグロメット４とカバー３との接着力が弱まり、最終的にはグロメット４とカバー３との接着は解かれる。これにより、グロメット４とカバー３との間に隙間を有する。これにより、コンデンサ２の防爆弁作動時にカバー３内に充満するガスがグロメット４とカバー３との間に出来る隙間から外部へ抜けて、カバー３内が減圧される。その結果、カバー３自体が爆発することを防止することができる。   Subsequently, when the pressure in the cover 3 exceeds a predetermined value less than the cover explosion-proof limit value by filling with mold resin or the like, the adhesive force between the grommet 4 and the cover 3 at the exposed portion 41 of the grommet 4 is weakened, and finally The grommet 4 and the cover 3 are unbonded. Thereby, there is a gap between the grommet 4 and the cover 3. As a result, the gas filling the cover 3 when the explosion-proof valve of the capacitor 2 is operated escapes to the outside through a gap formed between the grommet 4 and the cover 3, and the inside of the cover 3 is decompressed. As a result, the cover 3 itself can be prevented from exploding.

また、グロメット４の一部をカバー３の開口部周縁に形成した切欠部３１から露出させてあるため、カバー３の開口面全体をモールド樹脂で覆っても、常にグロメット４とカバー３との間に隙間を有することができる状態になるため、モールド樹脂の量を確認する作業を必要とせず、作業性が良くなる。   Further, since a part of the grommet 4 is exposed from the notch 31 formed at the periphery of the opening of the cover 3, even if the entire opening surface of the cover 3 is covered with mold resin, it is always between the grommet 4 and the cover 3. Therefore, there is no need to confirm the amount of mold resin, and workability is improved.

本発明によれば、ケースに組み込みモールド樹脂をカバーと接する面まで満たして硬化させた場合において、グロメットの一部を前記カバー開口部周縁に形成した切欠部から露出させ、前記カバー内の圧力がカバー防爆限界値未満の所定値を超えると、前記グロメットと前記カバーとの間に隙間を有するように構成してあることにより、コンデンサの防爆弁作動時に前記カバー内に充満するガスがグロメットとカバーとの間に出来る隙間から外部へ抜けて、カバー内が減圧され、その結果、コンデンサカバー自体が爆発することを防止することができ、産業上利用可能である。   According to the present invention, when the embedded mold resin is filled in the case up to the surface in contact with the cover and cured, a part of the grommet is exposed from the notch formed at the periphery of the cover opening, and the pressure in the cover is reduced. When a predetermined value that is less than the cover explosion-proof limit value is exceeded, a gap is formed between the grommet and the cover, so that the gas that fills the cover when the explosion-proof valve of the capacitor is operated is filled with the grommet and the cover. It is possible to prevent the capacitor cover itself from exploding because the inside of the cover is depressurized through the gap formed between the two and the outside, and this is industrially applicable.

また、グロメットの一部をカバー開口部周縁に形成した切欠部から露出させてあるため、カバー開口面全体をモールド樹脂で覆っても、常にグロメットとカバーとの間に隙間を有することができる状態になるため、モールド樹脂の量を確認する作業を必要とせず、作業性が良く、産業上利用可能である。   In addition, since a part of the grommet is exposed from the notch formed at the periphery of the cover opening, even when the entire cover opening is covered with mold resin, there is always a gap between the grommet and the cover. Therefore, the work of checking the amount of the mold resin is not required, the workability is good, and the industrial use is possible.

前記カバーと前記グロメットとを接着してあることにより、カバー内の圧力がカバー防爆限界値未満の所定値を超えた段階で、グロメットとカバーとの間に、容易に隙間を有することができ、確実にカバー内を減圧することができ、産業上利用可能である。   By adhering the cover and the grommet, it is possible to easily have a gap between the grommet and the cover when the pressure in the cover exceeds a predetermined value less than the cover explosion-proof limit value, The inside of the cover can be reliably depressurized and can be used industrially.
