Abstract
Description
本発明は、電気機器収納用箱における防水防塵効果を高めるための、電気機器収納用箱用パッキンに関するものである。 The present invention relates to an electrical equipment storage box packing for enhancing the waterproof and dustproof effect in the electrical equipment storage box.
電気機器をその内部に収納するための電気機器収納用箱等は、屋外で使用される場合があり、雨水や塵等が筐体内部に侵入しないように、電気機器収納用箱本体と扉部との間に弾性材料からなるパッキンが設けられている。 Electrical equipment storage boxes, etc., for storing electrical equipment inside may be used outdoors, and the electrical equipment storage box main body and door section should prevent rainwater, dust, etc. from entering the housing. Between them, a packing made of an elastic material is provided.
前記パッキンは、特許文献１のように、扉部の内側のうち、電気機器収納用箱本体の水切り部に対応する位置に、枠状に構成されることが通常である。さらに、前記パッキンとしては、中空パッキンが用いられ、発泡体を内包した直線状の直線部材同士を、コーナー部材を介して溶着することにより枠状に構成される。しかしながら、前記コーナー部材は、直線部材同士を溶着させる工程上、発泡体を含ませることが困難であり、弾性の低い箇所となってしまう。これにより、経年劣化によりコーナー部材の弾性が低下し、特に水切り部の角部における防水防塵機能が低下する問題があった。 As in Patent Document 1, the packing is usually configured in a frame shape at a position corresponding to the draining portion of the electric device storage box body inside the door portion. Further, as the packing, a hollow packing is used, and a linear shape member containing a foam is welded via a corner member to form a frame shape. However, it is difficult for the corner member to include a foam in the process of welding the linear members to each other, and the corner member has a low elasticity. Thereby, the elasticity of the corner member is lowered due to deterioration over time, and there is a problem that the waterproof and dustproof function at the corner portion of the draining portion is lowered.
パッキンを枠状に構成するその他の方法としては、発泡体を内包した直線状のパッキンを形成しさらに、パッキンを折り曲げることにより枠状とする方法がある。この方法によれば、前記コーナー部材に相当する箇所にも発泡体を内包させることが可能となるが、パッキンを折り曲げる際に皺が発生してしまい、前記と同様に水切り部の角部における防水防塵機能が低下する問題があった。 As another method for configuring the packing in a frame shape, there is a method in which a linear packing containing a foam is formed and the packing is bent to form a frame shape. According to this method, it is possible to enclose the foam in a portion corresponding to the corner member, but wrinkles are generated when the packing is bent, and the waterproofing at the corner of the draining portion is the same as described above. There was a problem that the dustproof function deteriorated.
そこで、前記パッキンの防水防塵機能を高めるためには、例えばパッキンの厚みを厚くする、または、パッキンの反発係数を高める、若しくはパッキンの硬度を上げる等の方法があるが、特に電気機器収納用箱のサイズが大きい場合には、このような方法を取ると扉部を閉塞する際に大きな力が必要となり、実用性に欠ける問題があった。 Therefore, in order to enhance the waterproof and dustproof function of the packing, for example, there is a method of increasing the thickness of the packing, increasing the coefficient of restitution of the packing, or increasing the hardness of the packing. In the case where the size is large, when such a method is adopted, a large force is required to close the door portion, and there is a problem of lack of practicality.
本発明の目的は前記した従来の問題点を解決し、扉部を閉塞する際に大きな力を要せず、かつ高い防水防塵機能を備えた電気機器収納用箱用パッキンを提供することである。 An object of the present invention is to solve the above-mentioned conventional problems, and to provide a packing for an electric equipment storage box that does not require a large force when closing a door and has a high waterproof and dustproof function. .

It is characterized by being attached to the door part.
請求項３記載の発明は、請求項２記載の電気機器収納用箱用パッキンにおいて、前記高反発パッキンは、前記扉部の閉塞時に、電気機器収納用箱本体の水切り部に当接する位置に設けたことを特徴とするものである。 According to a third aspect of the present invention, in the packing for an electric equipment storage box according to the second aspect, the high resilience packing is provided at a position where the high resilience packing contacts the draining portion of the electric equipment storage box main body when the door portion is closed. It is characterized by that.
請求項４記載の発明は、請求項３記載の電気機器収納用箱用パッキンにおいて、前記中空パッキンは、直線状の直線部材同士を、コーナー部材を介して溶着して枠状に形成されるものとし、前記溝部は、前記中空パッキンの表面に枠状に形成されるものとした上で、線状に形成された前記高反発パッキンを折り曲げて、前記溝部に保持させたことを特徴とするものである。 According to a fourth aspect of the present invention, in the packing for an electric equipment storage box according to the third aspect, the hollow packing is formed in a frame shape by welding linear straight members to each other via a corner member. The groove portion is formed in a frame shape on the surface of the hollow packing, and the high resilience packing formed in a linear shape is bent and held in the groove portion. It is.
本発明に係る電気機器収納用箱用パッキンは、中空パッキンと、この中空パッキンの表面に長手方向に形成された溝部と、この溝部に嵌め込まれて保持されるとともに、前記中空パッキンと比較して高い反発力を有する高反発パッキンとを備えるものとした。このように、高反発パッキンを、中空パッキンに形成した溝部によって保持させることにより、扉部を閉塞する際の反発力を低下させることができ、小さな力で扉部を閉塞することが可能となる。さらに、閉塞完了後は高反発パッキンによる高い防水防塵機能を備えることができる。 The packing for an electric equipment storage box according to the present invention includes a hollow packing, a groove formed in the longitudinal direction on the surface of the hollow packing, and fitted and held in the groove, as compared with the hollow packing.

以下に本発明の好ましい実施形態を示す。
電気機器を収納するための電気機器収納用箱は、図１に示すように、電気機器収納用箱本体１と、その開口部２を閉塞するための、図２に示す扉部３とからなる。さらに、この扉部３の内側には、電気機器収納用箱本体１に設けられた開口部２の周囲に枠状に形成された水切り部４に対応する位置に、雨水や塵等の侵入を防止するための電気機器収納用箱用パッキンが設けられる。
Preferred embodiments of the present invention are shown below.
As shown in FIG. 1, the electric device storage box for storing the electric device includes an electric device storage box body 1 and a door portion 3 shown in FIG. 2 for closing the opening 2. . Furthermore, intrusion of rain water, dust or the like is made inside the door portion 3 at a position corresponding to the draining portion 4 formed in a frame shape around the opening portion 2 provided in the electric equipment storage box body 1. An electrical equipment storage box packing is provided for prevention.
本発明の電気機器収納用箱用パッキンは、図２のように、枠状に形成された中空パッキン５と、その表面に形成された枠状の溝部９と、この溝部９に嵌め込まれて保持される高反発パッキン１０とにより構成される。また、中空パッキン５は、直線状に形成されたゴム等の弾性材料からなり、発泡体を含ませた直線部材６同士を、同様にゴム等の弾性材料からなるコーナー部材７を介して溶着してなるものとした。なお、前記中空パッキン５の内部には、空洞が形成されている。また、中空パッキン５は、図３及び図４のように断面半月状に成形するものとし、その曲面部８の略中央には、溝部９を形成するものとした。さらに、この溝部９には、中空パッキン５と比較して高い反発力や剛性を有する、ゴム等の弾性材料からなる断面円形状の高反発パッキン１０が嵌め込まれて保持される。高反発パッキン１０は、例えば中空パッキン５に対して密度を高くして反発力や剛性を高めるものとする。この高反発パッキン１０は、中空パッキン５と比較して、高反発のため変形に対しての反発力が強く、また高剛性のため変形し難く、高い水圧がかかった場合でも高い防水機能を有するものである。また、高反発パッキン１０は中空パッキン５と比較して高い反発力や剛性を有していればよく、高反発パッキン１０内部をパッキンで埋めたり、発泡体を含ませたり、内部を中空にしても良い。 As shown in FIG. 2, the packing for electrical equipment storage box according to the present invention has a hollow packing 5 formed in a frame shape, a frame-shaped groove portion 9 formed on the surface thereof, and is fitted and held in the groove portion 9. It is comprised by the high-repulsion packing 10 made. The hollow packing 5 is made of an elastic material such as rubber formed in a straight line, and the linear members 6 including foam are welded together via a corner member 7 made of an elastic material such as rubber. It was supposed to be. A cavity is formed inside the hollow packing 5. Moreover, the hollow packing 5 shall be shape | molded by the cross-sectional meniscus shape like FIG.3 and FIG.4, and the groove part 9 shall be formed in the approximate center of the curved surface part 8. FIG. Further, a high-rebound packing 10 having a circular cross section made of an elastic material such as rubber and having a higher repulsive force and rigidity than the hollow packing 5 is fitted and held in the groove 9. For example, the high repulsion packing 10 has a higher density than the hollow packing 5 to increase the repulsion force and rigidity. Compared to the hollow packing 5, the high repulsion packing 10 has a high repulsion force against deformation due to high repulsion, and is difficult to deform due to high rigidity, and has a high waterproof function even when high water pressure is applied. Is. Further, the high resilience packing 10 only needs to have higher resilience and rigidity than the hollow packing 5, and the inside of the high resilience packing 10 is filled with packing, contains a foam, or the inside is made hollow. Also good.
このように高反発パッキン１０を中空パッキン５の表面に形成した枠状の溝部９によって保持させることにより、図５のように、扉部３の閉塞時には、水切り部４が高反発パッキン１０に当接し、さらに高反発パッキン１０が押し込まれることにより中空パッキン５が容易に変形するため、反発力が低下し、小さな力で扉部３を閉塞することが可能となる。さらに、図５のように、閉塞完了後には、水切り部４に中空パッキン５の曲面部８と高反発パッキン１０とが圧着することにより、中空パッキン５による従来通りの防水防塵機能に加え、高反発パッキン１０による高い防水防塵機能を備えることができる。 By holding the high-repulsive packing 10 by the frame-shaped groove 9 formed on the surface of the hollow packing 5 as described above, the draining portion 4 contacts the high-repulsive packing 10 when the door 3 is closed as shown in FIG. Since the hollow packing 5 is easily deformed by contacting and further pushing the high-rebound packing 10, the repulsive force is reduced and the door portion 3 can be closed with a small force. Further, as shown in FIG. 5, after the closure is completed, the curved surface portion 8 of the hollow packing 5 and the high resilience packing 10 are pressure-bonded to the draining portion 4, in addition to the conventional waterproof and dustproof function by the hollow packing 5. A high waterproof and dustproof function by the rebound packing 10 can be provided.
また、図３及び図４のように、中空パッキン５は断面半月状とすることにより、溝部９と対向する位置に扉部３への取付箇所となる平坦部１１を設けることが好ましい。これにより、扉部３への中空パッキン５の取付が容易になると同時に、取付後には中空パッキン５が扉部３から剥がれにくくなる効果を有する。なお、本実施形態とは反対に、平坦部１１を水切り部４に取付け、中空パッキン５と高反発パッキン１０とを、扉部３と圧着させることにより扉部３を閉塞する構造としても差し支えない。 As shown in FIGS. 3 and 4, it is preferable that the hollow packing 5 has a semicircular cross section so that a flat portion 11 serving as an attachment location to the door portion 3 is provided at a position facing the groove portion 9. Thereby, attachment of the hollow packing 5 to the door portion 3 is facilitated, and at the same time, the hollow packing 5 is less likely to be peeled off from the door portion 3 after attachment. Contrary to the present embodiment, the flat part 11 may be attached to the draining part 4 and the door part 3 may be closed by pressing the hollow packing 5 and the high resilience packing 10 against the door part 3. .
本実施形態においては、高反発パッキン１０は、線状に形成されるものとし、これを折り曲げて枠状とすることにより、溝部９に保持させるものとした。さらに、高反発パッキン１０は、扉部３の閉塞時に、水切り部４に当接する位置に設けるものとした。これにより、扉部３の閉塞完了後には、図１の水切り部における角部１２にも、高反発パッキン１０が圧着されることとなり、コーナー部材７の弾性が低下したとしても、角部１２における防水防塵機能の低下を防止することが可能となる。 In the present embodiment, the high-rebound packing 10 is formed in a linear shape, and is held in the groove portion 9 by bending it into a frame shape. Further, the high resilience packing 10 is provided at a position where it comes into contact with the draining portion 4 when the door portion 3 is closed. Thereby, after completion of closing of the door part 3, even if the high resilience packing 10 is pressure-bonded to the corner part 12 in the draining part of FIG. 1, even if the elasticity of the corner member 7 is reduced, the corner part 12 It becomes possible to prevent the deterioration of the waterproof and dustproof function.
また、本実施形態においては、高反発パッキン１０を断面円形状としたことにより、扉部３の閉塞時に、水切り部４と点接触するため、より小さい力で扉部３を閉塞することを可能とした。なお、高反発パッキン１０は、中空パッキン５に対してその設置面積を小さいものとしたことにより、同様に、より小さい力で扉部３を閉塞することができる。さらに、高反発パッキン１０を断面円形状としたことにより、溝部９に嵌め込む際の向きを憂慮する必要がないため、作業性が高いという利点もある。 Moreover, in this embodiment, since the high resilience packing 10 has a circular cross section, the door portion 3 can be closed with a smaller force because it makes point contact with the draining portion 4 when the door portion 3 is closed. It was. In addition, the high repulsion packing 10 can close the door part 3 with a smaller force similarly by making the installation area small with respect to the hollow packing 5. Furthermore, since the high resilience packing 10 has a circular cross section, there is no need to worry about the direction when fitting into the groove 9, and there is an advantage that workability is high.
なお、中空パッキン５は、直線部材６とコーナー部材７とを溶着して枠状に形成することにより、皺の発生を防止するものとしたが、従来と同様に、直線状の中空パッキン５を形成し、中空パッキン５を枠状に折り曲げるものとしても良い。この場合は、中空パッキン５を折り曲げる際に皺が発生するものの、溝部９に高反発パッキン１０を嵌め込んで保持することにより、水切り部４の角部１２における防水防塵機能の低下を防止することができる。 The hollow packing 5 is formed by welding the linear member 6 and the corner member 7 into a frame shape to prevent wrinkles. However, as in the conventional case, the linear packing 5 is It is good also as what forms and bends the hollow packing 5 in frame shape. In this case, although wrinkles are generated when the hollow packing 5 is bent, the waterproof and dustproof function at the corner portion 12 of the draining portion 4 is prevented from being lowered by fitting and holding the high-repulsion packing 10 in the groove portion 9. Can do.
その他の実施形態として図６に示すように、中空パッキン５の形状は、断面四角形状とすることもできる。これにより、中空パッキン５の平坦部１１の面積を減少させることができ、特に中空パッキン５の取付箇所に制限がある場合に有効となる。 As shown in FIG. 6 as another embodiment, the shape of the hollow packing 5 may be a square cross section. Thereby, the area of the flat part 11 of the hollow packing 5 can be reduced, and it becomes effective especially when there is a limit in the attachment location of the hollow packing 5.
また、図７のように、防水防塵機能を高めるために、高反発パッキン１０を複数並べて溝部９に備えるものとすることもできる。その際には、高反発パッキン１０の数と同数の溝部９を形成することが好ましい。これらを組み合わせて、例えば図８のように２本の高反発パッキン１０を備えた断面四角形状の中空パッキン５とすることもできる。その他にも、平坦部１１の面積を大きくして、取付後の中空パッキン５の接着力を向上させた図９のような形状や、中空パッキン５と水切り部４との圧着力を高めるために、中空パッキン５の圧着側の角部に丸みを持たせた図１０のような形状としても良い。 Further, as shown in FIG. 7, in order to enhance the waterproof and dustproof function, a plurality of high resilience packings 10 may be arranged in the groove portion 9. In that case, it is preferable to form the same number of grooves 9 as the number of high-rebound packings 10. By combining these, for example, as shown in FIG. 8, a hollow packing 5 having a square cross section having two high-rebound packings 10 can be obtained. In addition, in order to increase the area of the flat part 11 and improve the adhesive force of the hollow packing 5 after mounting, as shown in FIG. 9, and the pressure bonding force between the hollow packing 5 and the draining part 4. Further, the hollow packing 5 may have a shape as shown in FIG.
なお、高反発パッキン１０の形状も、断面円形状に限定されず、例えば断面四角形状や断面三角形状等の多角形状とすることもできる。その際には、溝部の形状も高反発パッキン１０の形状に合わせたものとすることが好ましい。 The shape of the high resilience packing 10 is not limited to a circular cross section, and may be a polygonal shape such as a square cross section or a triangular cross section. In that case, it is preferable that the shape of the groove part is matched with the shape of the high-rebound packing 10.
