Description

本発明は、電子装置に関する。 The present invention relates to electronic devices.

例えば車載用の電子装置の筐体として、防水構造を必要とするものがあり、必要な防水性能を満たすために、前記筐体は、第１筐体（例えばケース）と、第２筐体（例えばカバー）を嵌合し、これら２つの筐体間の嵌合部にシール材（例えば接着剤）を充填するように構成されている。例えば特許文献１には、第１筐体と第２筐体の嵌合部の片方に凹部を形成すると共に、他方に前記凹部に間隙を持って嵌合する凸部を形成し、前記凹部にシール材を塗布して前記凸部を挿入することにより、シール材を介して２つの筐体間を密着させて封止する構成が記載されている。 For example, some housings of in-vehicle electronic devices require a waterproof structure. For example, a cover) is fitted, and the fitting portion between these two housings is filled with a sealing material (eg, adhesive). For example, in Patent Document 1, a concave portion is formed in one of the fitting portions of a first housing and a second housing, and a convex portion that fits in the concave portion with a gap is formed in the other, and the concave portion is formed with a gap. A configuration is described in which a sealing material is applied and the convex portion is inserted so that the two housings are brought into close contact with each other via the sealing material for sealing.

特開２００４－３５６５２３号公報JP 2004-356523 A

上記構成では、シール材を充填する凹部の内部において、底面と側面により形成された角部を丸めて曲面で構成することにより、２つの筐体を密着させる際に、凹部の角部に気泡、即ち、ボイドが滞留することを防ぐようにしている。しかし、シール材の硬化収縮によるボイドの成長あるいは新規発生する位置を予測できないという問題がある。このため、断面視において、シール材が密着する凹部あるいは凸部の界面における必要な接着強度を満足するために必要なシール密着長さ、即ち、シール長を安定して確保できないおそれがあった。
本発明の目的は、シール材を充填して２つの筐体を嵌合して密着させる構成において、シール長を安定して確保することができる電子装置を提供することにある。 In the above configuration, inside the concave portion filled with the sealing material, the corner formed by the bottom surface and the side surface is rounded to form a curved surface. That is, he is trying to prevent voids from remaining. However, there is a problem that it is not possible to predict the position where the void grows or newly occurs due to curing shrinkage of the sealing material. For this reason, in a cross-sectional view, there is a possibility that the seal adhesion length required to satisfy the necessary adhesion strength at the interface of the concave or convex portions to which the seal material adheres, that is, the seal length cannot be stably secured.
SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic device that can stably secure a seal length in a configuration in which two housings are fitted and closely attached by filling a sealing material.

請求項１の発明は、第１筐体４と、第２筐体６とを嵌合し、２つの筐体４、６間の嵌合部にシール材１２を充填した電子装置であって、前記第１筐体４の外周側に連続するように設けられた第１凹部９と、前記第２筐体６の外周側に連続するように設けられた第１凸部１０と、前記第１凸部１０の内側に断続的に設けられた第２凸部１１とを備えたものである。 The invention of claim 1 is an electronic device in which a first housing 4 and a second housing 6 are fitted together, and a fitting portion between the two housings 4 and 6 is filled with a sealing material 12, A first concave portion 9 provided so as to be continuous with the outer peripheral side of the first housing 4; a first convex portion 10 provided so as to be continuous with the outer peripheral side of the second housing 6; A second convex portion 11 is intermittently provided inside the convex portion 10 .

（第１実施形態）
以下、第１実施形態について、図１ないし図７を参照して説明する。本実施形態の電子装置１は、例えば車載用の電子装置であり、図１ないし図３に示すように、ほぼ箱状をなす筐体２と、筐体２内に収容された電子回路基板３とを備えて構成されている。筐体２は、図２及び図３に示すように、第１筐体を構成する例えば上面が開口した矩形状のケース４と、第２筐体を構成する例えば上記ケース４の開口部５を閉塞するカバー６とを有する。 (First embodiment)
A first embodiment will be described below with reference to FIGS. 1 to 7. FIG. The electronic device 1 of the present embodiment is, for example, a vehicle-mounted electronic device, and as shown in FIGS. and As shown in FIGS. 2 and 3, the housing 2 includes, for example, a rectangular case 4 having an open upper surface, which constitutes a first housing, and an opening 5 of, for example, the case 4 which constitutes a second housing. and a closing cover 6 .

ケース４の外周側である例えば周壁部７の上端面部８には、図５にも示すように、断面略コ字状の溝状をなす第１凹部９が連続するように設けられている。また、カバー６の内面、即ち、下面の外周側である例えば外周縁部には、図４にも示すように、第１凸部１０が連続するように設けられている。そして、カバー６の内面における第１凸部１０の内側には、複数の第２凸部１１が断続的に設けられている。第２凸部１１の高さ寸法は、第１凸部１０の高さ寸法とほぼ同じであり、第２凸部１１の厚み寸法は、第１凸部１０の厚み寸法とほぼ同じである。 On the outer peripheral side of the case 4, for example, on the upper end surface portion 8 of the peripheral wall portion 7, as shown in FIG. In addition, as shown in FIG. 4, a first convex portion 10 is continuously provided on the inner surface of the cover 6, that is, on the outer peripheral side of the lower surface, for example, on the outer peripheral edge. A plurality of second protrusions 11 are intermittently provided inside the first protrusions 10 on the inner surface of the cover 6 . The height dimension of the second protrusion 11 is substantially the same as the height dimension of the first protrusion 10 , and the thickness dimension of the second protrusion 11 is substantially the same as the thickness dimension of the first protrusion 10 .

この構成の場合、ケース４の開口部５をカバー６により閉塞するに際しては、ケース４の第１凹部９内にシール材１２を充填しておく。そして、図５にも示すように、ケース４の第１凹部９内にカバー６の第１凸部１０及び第２凸部１１を嵌合させる。これにより、ケース４とカバー６の嵌合部において、第１凹部９と第１凸部１０及び第２凸部１１との間の隙間内に、シール材１２が充填されて密着されるようになる。この結果、ケース４の開口部５がカバー６により水密に閉塞される構成となり、筐体２は所定の防水性能を有するように構成されている。 In this configuration, when closing the opening 5 of the case 4 with the cover 6 , the sealing material 12 is filled in the first concave portion 9 of the case 4 . Then, as shown in FIG. 5, the first convex portion 10 and the second convex portion 11 of the cover 6 are fitted into the first concave portion 9 of the case 4 . As a result, the gaps between the first concave portion 9 and the first convex portion 10 and the second convex portion 11 are filled with the sealing material 12 at the fitting portion of the case 4 and the cover 6 so as to be in close contact with each other. Become. As a result, the opening 5 of the case 4 is watertightly closed by the cover 6, and the housing 2 is configured to have a predetermined waterproof performance.

ここで、図５に示すように、第１凸部１０の先端部１０ａは、例えば断面半円形となるように丸め形成されている。第２凸部１１の先端部１１ａは、例えば断面矩形状となるように形成されている。そして、第１凸部１０の根本部分の角部１０ｂは、丸められて曲面となるように形成されている。第２凸部１１の根本部分の角部１１ｂは、丸められて曲面となるように形成されている。 Here, as shown in FIG. 5, the tip portion 10a of the first convex portion 10 is rounded so as to have, for example, a semicircular cross section. A tip portion 11a of the second convex portion 11 is formed to have, for example, a rectangular cross section. A corner portion 10b of the root portion of the first convex portion 10 is rounded to form a curved surface. A corner portion 11b of the root portion of the second convex portion 11 is rounded to form a curved surface.

また、図４中のＶＩ－ＶＩ線に沿う断面を示す図６に示すように、隣接する第２凸部１１の間の凹部１５の底面と側面により形成された角部１５ａは、ほぼ直角となるように形成されている。 Further, as shown in FIG. 6 showing a cross section along line VI-VI in FIG. It is formed to be

尚、筐体２の図１中の上部の壁部１３からは、電子回路基板３に実装されたコネクタ１４が上方へ向けて突設されている。壁部１３にコネクタ１４を貫通させるように形成された孔と、コネクタ１４との間は、例えば図示しないパッキンや接着剤等を介して水密にシールされている。 A connector 14 mounted on the electronic circuit board 3 protrudes upward from a wall portion 13 in the upper portion of the housing 2 in FIG. A hole formed in the wall portion 13 for the connector 14 to pass through and the connector 14 are watertightly sealed via, for example, a packing or an adhesive (not shown).

さて、上記構成において、ケース４内に電子回路基板３を収容した状態で、ケース４の開口部５をカバー６により閉塞するに際しては、ケース４の第１凹部９内にカバー６の第１凸部１０及び第２凸部１１を嵌合させると共に、嵌合部、即ち、第１凹部９と第１凸部１０及び第２凸部１１との間の隙間内にシール材１２を充填して硬化させる。この場合、シール材１２を硬化させるときに収縮が起こり、ボイドが発生する可能性が高くなる。 Now, in the above configuration, when closing the opening 5 of the case 4 with the electronic circuit board 3 housed in the case 4 , the first protrusion of the cover 6 is inserted into the first recess 9 of the case 4 . The portion 10 and the second convex portion 11 are fitted together, and the sealing material 12 is filled in the fitting portion, that is, the gap between the first concave portion 9 and the first convex portion 10 and the second convex portion 11. Harden. In this case, shrinkage occurs when the sealing material 12 is cured, increasing the possibility of voids being generated.

これに対して、本実施形態では、図６に示すように、隣接する第２凸部１１の間の凹部１５の角部１５ａを、ほぼ直角となるように形成したので、シール材１２の硬化収縮時に発生するボイドを、第２凸部１１の間の凹部１５内の角部１５ａ付近に誘導する、即ち、ボイドの発生位置を角部１５ａ付近に誘導することができる。この結果、図１中のＶＩＩ－ＶＩＩ線に沿う断面を示す図７に示すように、シール材１２の硬化収縮に起因するボイド１６は、第２凸部１１の間の凹部１５内の角部１５ａ付近に発生するようになる。 On the other hand, in the present embodiment, as shown in FIG. 6, the corners 15a of the concave portions 15 between the adjacent second convex portions 11 are formed to be approximately right angles, so that the sealing material 12 is hardened. Voids generated during contraction can be guided near the corners 15a in the recesses 15 between the second projections 11, that is, void generation positions can be guided near the corners 15a. As a result, as shown in FIG. 7 showing a cross section along line VII-VII in FIG. It comes to occur near 15a.

これにより、図５に示すように、シール材１２が密着する凹部９あるいは凸部１０、１１の界面における必要な接着強度を満足するために必要なシール密着長さ、即ち、図５にて１点鎖線Ａで示すシール長を安定して確保することができる。 As a result, as shown in FIG. 5, the seal adhesion length required to satisfy the necessary adhesive strength at the interface between the concave portion 9 or the convex portions 10 and 11 with which the sealing material 12 is in close contact, that is, 1 in FIG. The seal length indicated by the dotted chain line A can be stably ensured.

このような構成の本実施形態によれば、ケース４の外周側に第１凹部９を連続するように設け、カバー６の外周側に第１凸部１０を連続するように設け、第1凸部１０の内側に第２凸部１１を断続的に設けたので、シール材１２を充填してケース４とカバー６を嵌合して密着させる構成において、シール長を安定して確保することができる。これによって、筐体２の防水性能を向上させることができる。 According to this embodiment having such a configuration, the first concave portion 9 is continuously provided on the outer peripheral side of the case 4, the first convex portion 10 is continuously provided on the outer peripheral side of the cover 6, and the first convex portion 10 is provided continuously on the outer peripheral side of the cover 6. Since the second protrusions 11 are intermittently provided inside the portion 10, the sealing length can be stably secured in the structure in which the sealing material 12 is filled and the case 4 and the cover 6 are fitted and closely attached. can. Thereby, the waterproof performance of the housing 2 can be improved.

（第２実施形態）
図８ないし図１０は、第２実施形態を示すものである。尚、第１実施形態と同一構成には、同一符号を付している。第２実施形態では、図８に示すように、第２凸部１１の先端部、即ち、先端面２０には、第２凹部２１が形成されている。この第２凹部２１は、開口面と底面が所定の大きさであり且つ同一形状であり、設定深さを有する凹部である。第２凹部２１は、図９に示すように、第２凸部１１の先端面２０において、図９中の左右方向（即ち、図８中の紙面に直交する方向）に延びるように、溝状に形成されている。第２凹部２１の両端部は、第２凸部１１の図９中の左右の側面において開口している。 (Second embodiment)
8 to 10 show a second embodiment. In addition, the same code|symbol is attached|subjected to the same structure as 1st Embodiment. In the second embodiment, as shown in FIG. 8, a second concave portion 21 is formed in the tip portion of the second convex portion 11, that is, the tip surface 20. As shown in FIG. The second recess 21 has an opening surface and a bottom surface of a predetermined size and the same shape, and has a set depth. As shown in FIG. 9, the second concave portion 21 is formed in a groove-like shape on the distal end surface 20 of the second convex portion 11 so as to extend in the left-right direction in FIG. is formed in Both ends of the second concave portion 21 are open on the left and right side surfaces of the second convex portion 11 in FIG.

上述した以外の第２実施形態の構成は、第１実施形態の構成と同じ構成となっている。従って、第２実施形態においても、第１実施形態とほぼ同じ作用効果を得ることができる。特に、第２実施形態では、第２凸部１１の先端面２０に第２凹部２１を形成したので、第２凹部２１内にボイドが滞留し易くなることから、シール材１２を充填する部分、即ち、第１凹部９の内部において、ボイドが分散して発生するようになる。このため、シール材１２の硬化収縮によりボイドが成長しても、即ち、大きくなっても、各ボイドが繋がらないことから、安定したシール性を確保することができる。 The configuration of the second embodiment other than that described above is the same as the configuration of the first embodiment. Therefore, in the second embodiment as well, substantially the same effects as in the first embodiment can be obtained. In particular, in the second embodiment, since the second concave portion 21 is formed on the tip surface 20 of the second convex portion 11, voids tend to stay in the second concave portion 21. That is, voids are generated in a dispersed manner inside the first concave portion 9 . Therefore, even if the voids grow or become larger due to curing shrinkage of the sealing material 12, the voids are not connected to each other, so that stable sealing performance can be ensured.

尚、上記第２実施形態では、図９に示すように、第２凹部２１を左右方向に延ばして両端部が第２凸部１１の左右の側面において開口するように形成したが、これに代えて、図１０に示すように、第２凸部１１の先端面２０に複数個の第２凹部２２を形成するように構成しても良い。 In the above-described second embodiment, as shown in FIG. 9, the second concave portion 21 is extended in the left-right direction so that both ends are opened at the left and right side surfaces of the second convex portion 11. Alternatively, as shown in FIG. 10, a plurality of second recesses 22 may be formed on the tip surface 20 of the second protrusion 11 .

（第３実施形態）
図１１及び図１２は、第３実施形態を示すものである。尚、第１実施形態と同一構成には、同一符号を付している。第３実施形態では、図１１に示すように、第１実施形態の第２凸部１１に代えて、ほぼ円柱状をなす第２凸部２３を配設した。第２凸部２３は、第１凸部１０の内側に、第１凸部１０の側面に沿って所定の間隔で配置されている。 (Third embodiment)
11 and 12 show a third embodiment. In addition, the same code|symbol is attached|subjected to the same structure as 1st Embodiment. In the third embodiment, as shown in FIG. 11, in place of the second protrusion 11 of the first embodiment, a substantially cylindrical second protrusion 23 is provided. The second protrusions 23 are arranged inside the first protrusion 10 along the side surface of the first protrusion 10 at predetermined intervals.

第２凸部２３の高さ寸法は、第１実施形態の第２凸部１１の高さ寸法とほぼ同じであり、第２凸部２３の径寸法は、第２凸部１１の厚み寸法とほぼ同じである。図１２に示すように、第２凸部２３の先端面２４には、開口部が例えば矩形状の第２凹部２５が形成されている。 The height dimension of the second protrusion 23 is substantially the same as the height dimension of the second protrusion 11 of the first embodiment, and the diameter dimension of the second protrusion 23 is the same as the thickness dimension of the second protrusion 11. are almost the same. As shown in FIG. 12 , a second concave portion 25 having a rectangular opening, for example, is formed in the tip surface 24 of the second convex portion 23 .

上述した以外の第３実施形態の構成は、第１実施形態の構成と同じ構成となっている。従って、第３実施形態においても、第１実施形態とほぼ同じ作用効果を得ることができる。特に、第３実施形態では、第２凸部２３を円柱状に構成したので、第２凸部２３の側面が周面となり角部がなくなるため、応力の集中を防止することができ、第２凸部２３の側面とシール材１２の界面の剥離を防止することができる。また、第２凸部２３の形状が円柱状であるため、カバー６を製造する金型には、第２凸部２３形成用の円形の孔を単に形成するだけで済むことから、金型の製造が容易になるという生産上の効果が得られる。 The configuration of the third embodiment other than that described above is the same as the configuration of the first embodiment. Therefore, substantially the same effects as those of the first embodiment can be obtained also in the third embodiment. In particular, in the third embodiment, since the second convex portion 23 is configured in a cylindrical shape, the side surface of the second convex portion 23 becomes a peripheral surface and there are no corners. Separation of the interface between the side surface of the projection 23 and the sealing material 12 can be prevented. In addition, since the shape of the second convex portion 23 is cylindrical, it is sufficient to simply form a circular hole for forming the second convex portion 23 in the mold for manufacturing the cover 6. A production effect of facilitating manufacturing can be obtained.

（第４実施形態）
図１３ないし図１６は、第４実施形態を示すものである。尚、第３実施形態と同一構成には、同一符号を付している。第４実施形態では、図１３に示すように、第３実施形態の第２凸部２３に代えて、多角柱状例えば５角柱状をなす第２凸部２６を配設した。第２凸部２６の先端面２７には、図１４に示すように、開口部が例えば矩形状の第２凹部２５が形成されている。
上述した以外の第４実施形態の構成は、第３実施形態の構成と同じ構成となっている。 (Fourth embodiment)
13 to 16 show a fourth embodiment. In addition, the same code|symbol is attached|subjected to the same structure as 3rd Embodiment. In the fourth embodiment, as shown in FIG. 13, instead of the second protrusions 23 of the third embodiment, a second protrusion 26 having a polygonal prism shape, for example, a pentagonal prism shape is provided. As shown in FIG. 14, a second concave portion 25 having, for example, a rectangular opening is formed on the tip surface 27 of the second convex portion 26 .
The configuration of the fourth embodiment other than that described above is the same as the configuration of the third embodiment.

尚、上記第４実施形態では、第２凸部２６を５角柱状に形成したが、これに限られるものではなく、例えば３角柱状、４角柱状、６角柱状または７角以上の多角柱状に形成しても良い。図１５に、第２凸部２８を４角柱状に形成した例を示す。また、第２凹部２５の開口部の形状も、矩形状に限られるものではなく、他の種々の形状に形成しても良い。図１５には、第２凹部２９の開口部の形状を３角形に形成した例を示す。 In the above-described fourth embodiment, the second convex portion 26 is formed in the shape of a pentagonal prism, but it is not limited to this. may be formed to FIG. 15 shows an example in which the second convex portion 28 is formed in the shape of a quadrangular prism. Also, the shape of the opening of the second recess 25 is not limited to a rectangular shape, and may be formed in various other shapes. FIG. 15 shows an example in which the shape of the opening of the second recess 29 is triangular.

第２凹部２９の開口部の形状が３角形である構成の場合、第２凹部２９の内部の底面の形状も３角形であるから、第２凹部２９の底面の内角は、鋭角となる。このため、第２凹部２９の底面と第２凹部２９の内側面とが形成する角部付近にボイドが滞留し易くなるので、ボイドの位置をより一層制御し易くなる。 In the case where the shape of the opening of the second recess 29 is triangular, the bottom surface inside the second recess 29 also has a triangular shape, so the inner angle of the bottom surface of the second recess 29 is an acute angle. Therefore, the voids tend to stay near the corners formed by the bottom surface of the second recess 29 and the inner side surface of the second recess 29, making it easier to control the positions of the voids.

また、上記第４実施形態では、第２凸部２６、２８の先端面２７、３０には、図１４または図１５に示すように、１個の第２凹部２５または１個の第２凹部２９を形成したが、これに限られるものではなく、複数個の第２凹部を形成するように構成しても良い。図１６に、第２凸部２８の先端面３１に２個の第２凹部３２、３３を形成した例を示す。この例では、第２凹部３２、３３は、開口部の形状が３角形をなすように形成されており、２つの第２凹部３２、３３は互いに１８０度回転した位置関係となるように配置されている。これにより、第２凸部２８の先端面３１の面積が小さくても、２個の第２凹部３２、３３を配設することができる。このような構成によれば、第２凹部３２、３３の底面と内側面からなる鋭角の角部を、限られた面積内で増やすことができるため、角部付近におけるボイドの滞留が更に容易となり、ボイドの位置をより一層制御し易くなる。尚、第２凸部の先端面に、３個以上の第２凹部を形成するように構成しても良い。 14 or 15, one second concave portion 25 or one second concave portion 29 is provided on the end surfaces 27, 30 of the second convex portions 26, 28 in the fourth embodiment. is formed, but it is not limited to this, and a plurality of second recesses may be formed. FIG. 16 shows an example in which two second recesses 32 and 33 are formed on the tip surface 31 of the second protrusion 28 . In this example, the second recesses 32 and 33 are formed so that the shape of the opening forms a triangle, and the two second recesses 32 and 33 are arranged so as to have a positional relationship rotated by 180 degrees with respect to each other. ing. Thereby, even if the area of the tip surface 31 of the second protrusion 28 is small, the two second recesses 32 and 33 can be arranged. According to such a configuration, the number of acute corners formed by the bottom surfaces and the inner side surfaces of the second recesses 32 and 33 can be increased within a limited area, so voids can be more easily retained in the vicinity of the corners. , the position of the void is more controllable. In addition, it may be configured such that three or more second recesses are formed on the tip surface of the second protrusion.
