Description

本発明は、電気電子機器収納用箱の筐体とユニット間の防水構造に関するものである。 The present invention relates to a waterproof structure between a housing of an electric / electronic device storage box and a unit.

特許文献１に記載されているように、筐体の開口部にユニットを取り付ける際、開口部の周辺にパッキンを介在させて防水を行うことが知られている。 As described in Patent Document 1, when a unit is attached to an opening of a housing, it is known that a packing is interposed around the opening for waterproofing.

特開２００３－１５２３７３号公報Japanese Patent Application Laid-Open No. 2003-152373

ところで、このような筐体は屋外に設置されることが多い。筐体が屋外に設置された場合、開口部周辺に備えられたパッキンは外気に曝されやすいため、経年劣化により防水性能が損なわれやすかった。 By the way, such a housing is often installed outdoors. When the housing is installed outdoors, the packing provided around the opening is easily exposed to the outside air, so that the waterproof performance is likely to be impaired due to aging deterioration.

本件の発明者は、この点について鋭意検討することにより、解決を試みた。本発明の課題は、パッキンの経年劣化を抑制しつつ、防水性能を高めることが可能な構造を提供することである。 The inventor of this case tried to solve this problem by diligently examining this point. An object of the present invention is to provide a structure capable of improving waterproof performance while suppressing aging deterioration of packing.

上記課題を解決するため開口部が形成された電気電子機器収納用箱の筐体と、開口部を覆うように取り付けられるユニットと、を備え、開口部の周囲には筐体とユニットの間に内側パッキンと外側パッキンが配置されており、ユニットに対する反発力が内側パッキンと外側パッキンで互いに異なる電気電子機器収納用箱の筐体とユニット間の防水構造とする。 In order to solve the above problems, a housing of an electrical / electronic device storage box having an opening formed therein and a unit attached so as to cover the opening are provided, and the space around the opening is between the housing and the unit. The inner packing and the outer packing are arranged, and the repulsive force against the unit is different between the inner packing and the outer packing. The housing of the electrical and electronic device storage box and the unit have a waterproof structure.

筐体とユニットを固定する固定ねじを、内側パッキン及び外側パッキンよりも内側に配置し、ユニットに対する反発力は、内側パッキンよりも外側パッキンの方が弱い構成とすることが好ましい。 It is preferable that the fixing screw for fixing the housing and the unit is arranged inside the inner packing and the outer packing, and the repulsive force against the unit is weaker in the outer packing than in the inner packing.

内側パッキンと外側パッキンとの間に空隙を設けて配置した構成とすることが好ましい。 It is preferable to have a configuration in which a gap is provided between the inner packing and the outer packing.

ユニットのベース部は、内側パッキンと当接する部位の高さ位置と、外側パッキンと当接する高さ位置が異なる構成とすることが好ましい。 It is preferable that the base portion of the unit has a configuration in which the height position of the portion that abuts on the inner packing and the height position that abuts on the outer packing are different.

本発明では、パッキンの経年劣化を抑制しつつ、防水性能を高めることが可能な構造を提供することが可能となる。 INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a structure capable of improving waterproof performance while suppressing deterioration of the packing over time.

However, each packing has a connecting portion. 天井板とベース部間の距離を、内側パッキンが位置する部位と外側パッキンが位置する部位で異なる長さとした例を示した図であるIt is a figure which showed the example which made the distance between a ceiling plate and a base part different in the part where the inner packing is located, and the part where the outer packing is located.

以下に発明を実施するための形態を示す。図１及び図３に示されていることから理解されるように、本実施形態では、開口部２１が形成された電気電子機器収納用箱の筐体２と、開口部２１を覆うように取り付けられるユニット１とを備えている。また、開口部２１の周囲には筐体２とユニット１の間には、内側パッキン３１と、この内側パッキン３１の外周を囲うように、内側パッキン３１よりも外側に位置する外側パッキン３２が配置されている。そして、ユニット１に対する反発力が内側パッキン３１と外側パッキン３２で互いに異なるようにすることで、電気電子機器収納用箱の筐体２とユニット１間の防水構造を形成している。このため、外側パッキン３２が劣化しても、内側パッキン３１により防水性能を保つことができ、パッキンの経年劣化を抑制しつつ、防水性能を高めることが可能な構造を提供することが可能となる。 The embodiment for carrying out the invention is shown below. As can be understood from FIGS. 1 and 3, in the present embodiment, the housing 2 of the electrical / electronic device storage box in which the opening 21 is formed and the housing 2 of the electric / electronic device storage box are attached so as to cover the opening 21. It is equipped with a unit 1 that can be used. Further, around the opening 21, an inner packing 31 and an outer packing 32 located outside the inner packing 31 are arranged between the housing 2 and the unit 1 so as to surround the outer periphery of the inner packing 31. Has been done. By making the repulsive force against the unit 1 different between the inner packing 31 and the outer packing 32, a waterproof structure is formed between the housing 2 of the electrical and electronic device storage box and the unit 1. Therefore, even if the outer packing 32 deteriorates, the inner packing 31 can maintain the waterproof performance, and it is possible to provide a structure capable of improving the waterproof performance while suppressing the aging deterioration of the packing. ..

本実施形態のユニット１は換気扇ユニットとして説明する。本実施形態の換気扇ユニットは、換気扇１２を固定する部材でケース状に形成したベース部１３を備えている。このベース部１３には通気口１４が四方の辺に形成されている。図３に示す例においては、通気口１４にフィルタ９１を取り付けており、筐体２内の汚損を抑制している。また、四方の通気口１４を覆うように取り付けられるフード１５を備えている。このフード１５は、ベース部１３に対して着脱可能となるように構成されている。より具体的にはフード１５はベース部１３に対してねじ等を用いて固定されている。 The unit 1 of the present embodiment will be described as a ventilation fan unit. The ventilation fan unit of the present embodiment includes a base portion 13 formed in a case shape by a member for fixing the ventilation fan 12. Vents 14 are formed on all sides of the base portion 13. In the example shown in FIG. 3, a filter 91 is attached to the vent 14 to suppress contamination inside the housing 2. It also includes a hood 15 that is attached so as to cover the vents 14 on all sides. The hood 15 is configured to be removable from the base portion 13. More specifically, the hood 15 is fixed to the base portion 13 by using screws or the like.

ベース部１３の底部には開口１６を形成している。また換気扇１２は、この開口１６内に差し込まれるようにして取り付けられる。ベース部１３の裏面側には、筐体２に設けられた開口部２１の四辺を挟止するための押さえ板１７が備えられている。この押さえ板１７は、固定ねじ１８の締め付けにより、ベース部１３と押さえ板１７で天井板２２を挟止して固定するものである。 An opening 16 is formed at the bottom of the base portion 13. Further, the ventilation fan 12 is installed so as to be inserted into the opening 16. On the back surface side of the base portion 13, a pressing plate 17 for sandwiching the four sides of the opening 21 provided in the housing 2 is provided. The holding plate 17 sandwiches and fixes the ceiling plate 22 between the base portion 13 and the holding plate 17 by tightening the fixing screw 18.

ベース部１３と天井板２２との間には内側パッキン３１と外側パッキン３２が介在している。本実施形態では、内側パッキン３１と外側パッキン３２の各々は、枠体状に形成されており、開口部２１を囲うように配置されている。なお、各々のパッキンは一連で形成するものであっても良いし、複数のパッキンを組み合わせて枠体状にするものであっても良い。複数のパッキンを組み合わせて使用する場合、図４に示すように、内外のパッキンの繋ぎ部９３をそれぞれ反対側に設けた構成とすれば、パッキンの繋ぎ部９３を少なくできるとともに、水の浸入を効果的に防止することができる。図５に示すように内側パッキン３１と外側パッキン３２が各々一つの部材で構成されていても、繋ぎ部９３を備える場合がある。この場合も内外のパッキンの繋ぎ部９３をそれぞれ反対側に設けた構成とすれば、水の浸入を効果的に防止することができる。 An inner packing 31 and an outer packing 32 are interposed between the base portion 13 and the ceiling plate 22. In the present embodiment, each of the inner packing 31 and the outer packing 32 is formed in a frame shape and is arranged so as to surround the opening 21. Each packing may be formed in a series, or a plurality of packings may be combined to form a frame. When a plurality of packings are used in combination, as shown in FIG. 4, if the connecting portions 93 of the inner and outer packings are provided on opposite sides, the number of connecting portions 93 of the packings can be reduced and water can not enter. It can be effectively prevented. As shown in FIG. 5, even if the inner packing 31 and the outer packing 32 are each composed of one member, the connecting portion 93 may be provided. In this case as well, if the connecting portions 93 of the inner and outer packings are provided on opposite sides, the intrusion of water can be effectively prevented.

本実施形態では、筐体２とユニット１を固定する固定ねじ１８を、内側パッキン３１及び外側パッキン３２よりも内側に配置している。より具体的には、内側パッキン３１の内側に換気扇ユニットを天井板２２へ固定するために用いる固定ねじ１８を配置している。また、内側パッキン３１及び外側パッキン３２がもたらすユニット１に対する反発力は、内側パッキン３１よりも外側パッキン３２の方が弱くなるように構成されている。このため、内側パッキン３１及び外側パッキン３２には、固定ねじ１８を通すための加工が不要となり、水の浸入を効果的に防止することができる。 In the present embodiment, the fixing screw 18 for fixing the housing 2 and the unit 1 is arranged inside the inner packing 31 and the outer packing 32. More specifically, a fixing screw 18 used for fixing the ventilation fan unit to the ceiling plate 22 is arranged inside the inner packing 31. Further, the repulsive force of the inner packing 31 and the outer packing 32 with respect to the unit 1 is configured to be weaker in the outer packing 32 than in the inner packing 31. Therefore, the inner packing 31 and the outer packing 32 do not need to be processed to pass the fixing screw 18, and the intrusion of water can be effectively prevented.

本実施形態では、外側パッキン３２は柔らかい部材で反発力が低い部材としている。また、内側パッキン３１は硬い部材で反発力が高い部材としている。反発力が高いパッキンは天井板２２とベース部１３に押し付けようとする力により防水性能を高めることができるが、天井板２２を押し付ける力も大きくなり、天井板２２が変形しようとする。しかし、このパッキンを筐体２とユニット１を固定する固定ねじ１８の近辺に配置すれば、パッキンから生じる天井板２２を押し付けようとする力を固定ねじ１８で吸収することが可能となる。そこで本実施形態では、筐体２とユニット１を固定する固定ねじ１８を、反発力が高い部材で形成した内側パッキン３１の近傍に配置している。このようにすることにより、内側パッキン３１側を反発力が高い部材で形成しても、天井板２２の変形を防止しつつ固定できる。 In the present embodiment, the outer packing 32 is a soft member having a low repulsive force. Further, the inner packing 31 is a hard member and has a high repulsive force. The packing having a high repulsive force can improve the waterproof performance by the force of pressing against the ceiling plate 22 and the base portion 13, but the force of pressing the ceiling plate 22 also increases and the ceiling plate 22 tends to be deformed. However, if this packing is arranged in the vicinity of the fixing screw 18 for fixing the housing 2 and the unit 1, the force for pressing the ceiling plate 22 generated from the packing can be absorbed by the fixing screw 18. Therefore, in the present embodiment, the fixing screw 18 for fixing the housing 2 and the unit 1 is arranged in the vicinity of the inner packing 31 formed of a member having a high repulsive force. By doing so, even if the inner packing 31 side is formed of a member having a high repulsive force, the ceiling plate 22 can be fixed while being prevented from being deformed.

一方、固定ねじ１８から離れる外側パッキン３２は柔らかい部材で形成している。柔らかい部材で形成された外側パッキン３２は、ベース部１３の固定面や天井板２２への追従性が良いため、天井板２２または、ベース部１３と外側パッキン３２の隙間を小さくでき、防水性を高めることができる。 On the other hand, the outer packing 32 separated from the fixing screw 18 is made of a soft member. Since the outer packing 32 made of a soft member has good followability to the fixed surface of the base portion 13 and the ceiling plate 22, the gap between the ceiling plate 22 or the base portion 13 and the outer packing 32 can be reduced to improve waterproofness. Can be enhanced.

パッキンの保持方法としては、天井板２２に設けられた開口１６の周縁に孔を設け、その孔にねじを通過させて固定するものでも良いが、本実施形態では、押さえ板１７を用いることで、パッキンを面で挟止しつつ固定する固定構造である。このようにすれば、内側パッキン３１に対して比較的広範囲に荷重を均一に加えることができ、パッキンと天井板２２の間に隙間が生じることを抑制できる。なお、内側パッキン３１に均一の荷重を加える為に、反発力が高いパッキンを略全て覆うように押さえ板１７を設けることが好ましい。また、本実施形態の押さえ板１７は略コ字状としており、締め付け時に生じる押さえ板１７の変形をコ字状の腕部で防止している。勿論、外側パッキン３２を覆うように押さえ板１７を設けることにより、より効果的に防水性能を高めることが可能である。 As a method of holding the packing, a hole may be provided in the peripheral edge of the opening 16 provided in the ceiling plate 22 and a screw may be passed through the hole to fix the packing. However, in the present embodiment, the holding plate 17 is used. , It is a fixed structure that fixes the packing while sandwiching it with a surface. By doing so, the load can be uniformly applied to the inner packing 31 over a relatively wide range, and it is possible to suppress the formation of a gap between the packing and the ceiling plate 22. In order to apply a uniform load to the inner packing 31, it is preferable to provide a holding plate 17 so as to cover substantially all of the packing having a high repulsive force. Further, the pressing plate 17 of the present embodiment has a substantially U-shape, and the deformation of the pressing plate 17 that occurs during tightening is prevented by the U-shaped arm portion. Of course, by providing the pressing plate 17 so as to cover the outer packing 32, it is possible to more effectively enhance the waterproof performance.

パッキンはベース部１３に対して固定される。本実施形態では、ベース部１３の端部を折り曲げて形成した当接片６１がベース部１３の四方に設けられており、この当接片６１の内側の空間にパッキンを配置している。このため、当接片６１によって外側パッキン３２が外気に触れることを抑制することができる。また、押さえ板１７を締め付けて、ある程度パッキンを押し潰すと、天井板２２と当接片６１が当接する。したがって、必要以上にパッキンを押し潰すことを回避できる。なお、パッキンを押し潰し続けると弾性変形量が少なくなり、防水できなくなる恐れもあるが、当接片６１を形成することによりパッキンが過度に押し潰されることを防止できる。なお、本実施形態のパッキンは天井板２２の開口部２１周辺に貼り付けるものでも良い。 The packing is fixed to the base portion 13. In the present embodiment, contact pieces 61 formed by bending the ends of the base portion 13 are provided on all four sides of the base portion 13, and packings are arranged in the space inside the contact pieces 61. Therefore, the contact piece 61 can prevent the outer packing 32 from coming into contact with the outside air. Further, when the holding plate 17 is tightened and the packing is crushed to some extent, the ceiling plate 22 and the contact piece 61 come into contact with each other. Therefore, it is possible to avoid crushing the packing more than necessary. If the packing is continuously crushed, the amount of elastic deformation is reduced and waterproofing may not be possible. However, by forming the contact piece 61, it is possible to prevent the packing from being crushed excessively. The packing of the present embodiment may be attached around the opening 21 of the ceiling plate 22.

ところで、内側パッキン３１と外側パッキン３２は空隙９５を設けて配置することが好ましい。内側パッキン３１と外側パッキン３２は密着させて形成しても良いが、内側パッキン３１と外側パッキン３２の配置時に、互いに密着させておくと、ベース部１３から圧縮力が働いた場合、内側パッキン３１と外側パッキン３２が対向する面側には変形できず、垂直方向に力を逃がそうとする場合がある。この場合、状況によっては、その逃がした力が天井板２２やベース部１３を変形させる虞もある。そこで、本実施形態では、内側パッキン３１と外側パッキン３２の配置時に、内側パッキン３１と外側パッキン３２との間に空隙９５を設けている。このようにすると、ベース部１３から圧縮力が働いた場合でも、内側パッキン３１と外側パッキン３２の間にパッキンが変形できるスペースが生じる。したがって、天井板２２やベース部１３を変形させる力が発生することが抑制され、防水に対する信頼性を向上できる。 By the way, it is preferable that the inner packing 31 and the outer packing 32 are arranged with a gap 95 provided. The inner packing 31 and the outer packing 32 may be formed in close contact with each other, but if the inner packing 31 and the outer packing 32 are placed in close contact with each other when the inner packing 31 and the outer packing 32 are arranged, the inner packing 31 may be formed in close contact with each other when a compressive force is applied from the base portion 13. And the outer packing 32 cannot be deformed to the opposite surface side, and may try to release the force in the vertical direction. In this case, depending on the situation, the released force may deform the ceiling plate 22 and the base portion 13. Therefore, in the present embodiment, when the inner packing 31 and the outer packing 32 are arranged, a gap 95 is provided between the inner packing 31 and the outer packing 32. In this way, even when a compressive force is applied from the base portion 13, a space is created between the inner packing 31 and the outer packing 32 so that the packing can be deformed. Therefore, it is possible to suppress the generation of a force that deforms the ceiling plate 22 and the base portion 13, and improve the reliability of waterproofing.

内側パッキン３１と外側パッキン３２の反発力を異ならせるには、パッキンをそれぞれ異なる材質とすることが考えられる。また、各々のパッキンが同一面上に配置されている場合、各々のパッキンとベース部１３との当接面の高さ位置を変えることにより同種類のパッキンであっても反発力を異なるものとすることもできる。この場合、ベース部１３の高さが低いほうがパッキンの反発力が高くなり、ベース部１３の高さが高いほうがパッキンの反発力が低くなる。このように、ベース部１３とパッキンとの当接高さ位置を異ならせるだけでも反発力を異ならせるようにすることができる。そこで、図６に示す例では、ユニット１のベース部１３は、内側パッキン３１と当接する部位の高さ位置と、外側パッキン３２と当接する高さ位置が異なるように構成している。なお、パッキンの圧縮率が高いと天井板２２に向けた弾性力が高くなる。 In order to make the repulsive forces of the inner packing 31 and the outer packing 32 different, it is conceivable that the packings are made of different materials. Further, when each packing is arranged on the same surface, the repulsive force is different even for the same type of packing by changing the height position of the contact surface between each packing and the base portion 13. You can also do it. In this case, the lower the height of the base portion 13, the higher the repulsive force of the packing, and the higher the height of the base portion 13, the lower the repulsive force of the packing. In this way, it is possible to make the repulsive force different just by changing the contact height position between the base portion 13 and the packing. Therefore, in the example shown in FIG. 6, the base portion 13 of the unit 1 is configured so that the height position of the portion that abuts on the inner packing 31 and the height position that abuts on the outer packing 32 are different. If the compressibility of the packing is high, the elastic force toward the ceiling plate 22 becomes high.

以上、一つの実施形態を中心に説明してきたが、本発明は上記実施形態に限定されることはなく、各種の態様とすることが可能である。例えばパッキンは繋ぎ部が無い一続きのパッキンとすることもできる。 Although the above description has focused on one embodiment, the present invention is not limited to the above embodiment and can be various modes. For example, the packing may be a continuous packing having no joint.

また、パッキンは略四角形状とする必要は無く、開口部の形状に合わせて、略円形状などにすることも可能である。 Further, the packing does not have to have a substantially quadrangular shape, and can be formed into a substantially circular shape or the like according to the shape of the opening.

また、ユニットは換気扇ユニットである必要性は無い。例えば、筐体内に搭載される電気機器の冷却を行う冷却装置や、フード部材などにすることができる。 Also, the unit does not have to be a ventilation fan unit. For example, it can be a cooling device for cooling an electric device mounted in a housing, a hood member, or the like.
