Description
【０００１】[0001]
本考案は、電気接続箱やセンサ内蔵ケース等におけるケース本体とカバーとの 防水ないしは密閉のためのシール構造に関するものである。 The present invention relates to a seal structure for waterproofing or hermetically closing a case body and a cover in an electric connection box, a case with a built-in sensor or the like.

図７は、実開平１−５８９８３号公報に記載された従来のケースのシール構造 を示す分解斜視図、図８は、その組立状態を示す要部縦断面図である。 図で、２５は、コネクタ部２６を収納した合成樹脂製のケース本体、２７は、 係止手段２８，２９により該ケース本体２５に接合する合成樹脂製のカバー、３ ０は、該カバー２７とケース本体２５との間に配設されるゴム製の防水パッキン を示す。 FIG. 7 is an exploded perspective view showing a conventional seal structure of a case described in Japanese Utility Model Laid-Open No. 1-58983, and FIG. 8 is a longitudinal sectional view of an essential part showing its assembled state. In the figure, 25 is a case body made of synthetic resin accommodating the connector portion 26, 27 is a cover made of synthetic resin which is joined to the case body 25 by locking means 28, 29, 30 is the cover 27. A rubber waterproof packing provided between the case main body 25 and the case main body 25 is shown.
【０００３】 該パッキン３０は、図８に示す如く、断面矩形状を呈し、カバー２７の周縁部 ３１内に嵌着され、ケース本体２５の開口側端面３２に押圧されて密着すること により、外部からの水の浸入を阻止するものである。 しかしながら、上記従来の構造にあっては、特にパッキン３０の周長が長い場 合に、前記開口側端面３２の押圧力にムラが生じて密着が弱くなったり、押圧に よりパッキン３０の側部３０ａが捲れたりして、シール性が悪くなるという問題 があった。As shown in FIG. 8, the packing 30 has a rectangular cross section, is fitted into the peripheral portion 31 of the cover 27, and is pressed against the opening-side end surface 32 of the case body 25 so as to come into close contact with the outside thereof. It prevents the entry of water from. However, in the above-described conventional structure, particularly when the circumference of the packing 30 is long, the pressing force of the opening-side end surface 32 becomes uneven and the adhesion is weakened, or the side portion of the packing 30 is pressed by pressing. There is a problem that the sealing property is deteriorated because the 30a is rolled.
【０００４】[0004]
本考案は、上記した点に鑑み、パッキンの全長が長い場合でも、ケース本体と カバーとの間に確実に密着し、捲れることもなく、良好なシール性を発揮するこ とのできるケースのシール構造を提供することを目的とする。 In view of the above points, the present invention provides a case in which even if the total length of the packing is long, the case body and the cover are surely brought into close contact with each other and are not rolled up, and good sealing performance can be exhibited. It is intended to provide a seal structure.
【０００５】[0005]
上記目的を達成するために、本考案は、ケース本体とカバーとをパッキンを介 して接合するケースのシール構造において、該パッキンの片側ないし両側の接合 面に一定溝幅の周溝を設け、該ケース本体とカバーとの何れか一方あるいは両方 に、該周溝に対するテーパ形状の嵌合突条を周設すると共に、該接合面と交差す る該パッキンの側面に対する押接面を形成してなる構造を採用するものである。 In order to achieve the above object, the present invention provides a case seal structure in which a case body and a cover are joined via a packing, and a circumferential groove having a constant groove width is provided on one or both joint surfaces of the packing. On either or both of the case main body and the cover, a tapered fitting protrusion for the peripheral groove is provided, and a pressing surface for the side surface of the packing intersecting with the joint surface is formed. The following structure is adopted.
【０００６】[0006]
パッキンの周溝にテーパ形状の嵌合突条が係合することにより、パッキンに接 合方向の押圧力と該接合方向と直交する方向の押圧力とが作用し、パッキンの交 差する二面で密着したシーリングが行われる。また、後者の押圧力によりパッキ ン側部の捲れが防止される。従って、良好なシール性が発揮される。 When the tapered fitting protrusion is engaged with the circumferential groove of the packing, the pressing force in the joining direction and the pressing force in the direction orthogonal to the joining direction act on the packing, and the two surfaces where the packing intersects each other. A tight sealing is performed. In addition, the latter pressing force prevents the side portions of the packing from curling. Therefore, good sealability is exhibited.

図１は、本考案のケースのシール構造を適用した自動車のエアバック用センサ 内蔵ケースを示す側面図、図２は、同じくカバーを外した状態の図１の矢視Ａ正 面図、図３は、同じくカバー（内側面）を示す正面図である。 このケース１は、上部を開口した合成樹脂製のケース本体２とカバー３とによ り構成され、該ケース１内には、コネクタ端子４を有するセンサ５をブラケット ６で把持した状態で、ブラケット孔７から保護用のエポキシ樹脂剤８を注入充填 して固定させている。該カバー３は、ケース本体２に接合した状態で、該樹脂剤 ８によって固着される。 FIG. 1 is a side view showing a case with a built-in air bag sensor for an automobile to which the case seal structure of the present invention is applied, and FIG. 2 is a front view taken along arrow A in FIG. [Fig. 4] is a front view showing a cover (inner side surface) similarly. The case 1 is composed of a case body 2 made of a synthetic resin with an open top and a cover 3. In the case 1, a sensor 5 having a connector terminal 4 is held by a bracket 6, The epoxy resin agent 8 for protection is injected and filled from the hole 7 and fixed. The cover 3 is fixed to the case body 2 by the resin agent 8 in a state of being joined to the case body 2.
【０００８】 従って、ケース本体２とカバー３との接合部９には、防水性と共に注入樹脂剤 ８に対する密封性が必要となる。そのために、本考案は以下のような構造を採用 している。 すなわち、カバー３に対するケース本体２の接合面１０には、両側にテーパ面 １１ａ，１１ａを有する後述するテーパ状の嵌合突条１１を突出周設し、カバー ３には、該嵌合突条１１に対する一定溝幅ｄの周溝１２を有する含油ゴム製のパ ッキン１３を設けている。Therefore, the joint portion 9 between the case body 2 and the cover 3 is required to have a waterproof property as well as a sealing property with respect to the injected resin agent 8. Therefore, the present invention adopts the following structure. That is, the joint surface 10 of the case main body 2 with respect to the cover 3 is provided with a tapered fitting protrusion 11 having tapered surfaces 11a, 11a on both sides, and the cover 3 is provided with the fitting protrusion. An oil-impregnated rubber packing 13 having a circumferential groove 12 having a constant groove width d with respect to 11 is provided.
【０００９】 図４〜６は、このシール構造を示す要部拡大図であり、図で、２は、ケース本 体、３は、カバー、１３は、パッキンを示す。 該カバー３の周壁１４の先端部には、パッキン１３に対する接合面１５と、該 接合面１５に直交して突出する外縁部１６とを形成すると共に、該接合面１５に 隣接してパッキン固定用の突起１７（図３参照）を設けてある。4 to 6 are enlarged views of a main part of this seal structure, in which 2 is a case body, 3 is a cover, and 13 is a packing. At the tip of the peripheral wall 14 of the cover 3, a joint surface 15 for the packing 13 and an outer edge portion 16 projecting orthogonally to the joint surface 15 are formed, and a packing fixing member is provided adjacent to the joint surface 15 for fixing the packing. Projections 17 (see FIG. 3) are provided.
【００１０】 該パッキン１３には、該接合面１５に対する当接面１８と、該当接面１８に直 交して外縁部１６の内面（押接面）１６ａに対する接触面（側面）１９と、該突 起１７に対する係合孔２０とを形成すると共に、ケース本体２の接合面１０に対 向する当接面２１の該接触面１９寄りに、前記テーパ面１１ａを有するテーパ状 の嵌合突条１１に対する一定溝幅ｄの周溝１２を形成してある。 該嵌合突条１１は、先端に向けて縮幅する両側テーパ面１１ａ，１１ａを有す るテーパ形状に形成され、該周溝１２の溝幅ｄは、嵌合突条１１の先端部の幅Ｄ と同程度に小さく設定されている。In the packing 13, a contact surface 18 for the joint surface 15, a contact surface (side surface) 19 for directly contacting the contact surface 18 and an inner surface (pressing contact surface) 16 a of the outer edge portion 16, An engaging hole 20 for the protrusion 17 is formed, and a tapered fitting projection strip having the tapered surface 11a is provided near the contact surface 19 of the contact surface 21 facing the joint surface 10 of the case body 2. A peripheral groove 12 having a constant groove width d with respect to 11 is formed. The fitting projection 11 is formed in a tapered shape having tapered surfaces 11a on both sides which are narrowed toward the tip, and the groove width d of the circumferential groove 12 is the same as that of the tip of the fitting projection 11. It is set to be as small as the width D.
【００１１】 従って、図６に示す如く、パッキン１３の組付接合状態において、パッキン１ ３に接合方向（矢印イ，イ方向）の押圧力と、直交する方向（矢印ロ，ロ方向） の押圧力とが作用し、パッキン１３の表裏の当接面１８，２１と側部の接触面１ ９とが、カバー３及びケース本体２の接合面１５，１０とカバー３の外縁部内面 １６ａに押し付けられて密着し、良好なシール性が発揮される。また、直交する 方向（矢印ロ方向）の押圧力によりパッキン側部１９の捲れも防止される。Therefore, as shown in FIG. 6, when the packing 13 is assembled and bonded, the packing 13 is pressed in the bonding direction (arrows A and B) in a direction orthogonal to the pressing force (arrows B and B). By the action of pressure, the contact surfaces 18 and 21 on the front and back of the packing 13 and the contact surface 19 on the side are pressed against the joint surfaces 15 and 10 of the cover 3 and the case body 2 and the inner surface 16a of the outer edge of the cover 3. It is adhered and adheres, and a good sealing property is exhibited. Further, the packing side portion 19 is prevented from being rolled up by the pressing force in the orthogonal direction (arrow B direction).
【００１２】 なお、上記構造において、テーパ面１１ａを有するテーパ状の嵌合突条１１は 、カバー３側に設けても、あるいはケース本体２とカバー３の両方に設けてもよ い。また、本考案のケースのシール構造は、センサ内蔵ケース１に限らず、従来 例で示したような電気接続箱のケースにも適用が可能である。In the above structure, the tapered fitting protrusion 11 having the tapered surface 11 a may be provided on the cover 3 side or on both the case body 2 and the cover 3. Further, the case seal structure of the present invention is not limited to the sensor built-in case 1 and can be applied to the case of the electric junction box as shown in the conventional example.
【００１３】[0013]
以上の如くに、本考案によれば、パッキンの接合方向と、直交する方向との二 方向に押圧力が作用して、パッキンをケースの交差する二面で密着させると共に 、パッキン側部の捲れを防ぐから、パッキンの全長が長い場合でも、水の浸入や ケース内の充填剤の洩れ等を確実に防ぐことができるものである。 As described above, according to the present invention, the pressing force acts in two directions, the joining direction of the packing and the direction orthogonal to each other, to bring the packing into close contact with two intersecting surfaces of the case and to roll up the packing side portion. Therefore, even if the packing has a long length, it is possible to reliably prevent the infiltration of water and the leakage of the filler in the case.
