Abstract

PROBLEM TO BE SOLVED: To provide a small electronic device case which prevents the cost increase and achieves waterproofness with simple structure.SOLUTION: A case 7 includes a body 1, which has an opening at a front surface side and has the shape of a rectangle elongated in a vertical direction, and a cover 2 which is assembled to the body 1 so as to block the opening of the body 1. A rib 2h, projecting toward the body 1 side, is formed in a rectangular frame-like shape on the backside of the cover 2 so as to contact with an entire inner peripheral of an opening edge of the body 1. Further, a groove 2j is provided at an area of the rib 2h, which faces the inner peripheral of the opening edge of the body 1. Thus, even when water intrudes from a joint portion between the body 1 and the cover 2, water is accumulated in the groove 2j. Therefore, this structure prevents water from intruding into the inside of the body 1 and achieves waterproofness.

Description

本発明は、電子機器のケースに関するものである。   The present invention relates to a case of an electronic device.

従来より、屋内に設置されたり、防水構造を備えた屋外ボックスに収納されて屋外に設置される電子機器（例えば電子式電力量計など）が提供されている。   2. Description of the Related Art Conventionally, electronic devices (for example, an electronic watt hour meter) that are installed indoors or stored outdoors in an outdoor box having a waterproof structure have been provided.

図４は従来の電子機器の一例であり、前面側が開口する矩形箱状のボディ１、及び、開口を閉塞するようにしてボディ１に組み付けられるカバー２で構成されるケース７を備える。ケース７の内部には、複数のプリント基板４，５により構成される電子回路８が収納されており、ケース７の前面側には厚みの薄い矩形箱状の蓋体３が組み付けられている。そして、一体に組み付けられた電子機器は、そのままの形で屋内に設置されるか、または上記の屋外ボックスに収納されて屋外に設置されることになる。   FIG. 4 shows an example of a conventional electronic device, which includes a case 7 including a rectangular box-shaped body 1 whose front side is open and a cover 2 that is assembled to the body 1 so as to close the opening. An electronic circuit 8 composed of a plurality of printed circuit boards 4 and 5 is housed inside the case 7, and a thin rectangular box-shaped lid 3 is assembled on the front side of the case 7. And the electronic device assembled | attached integrally is installed indoors as it is, or is accommodated in said outdoor box and installed outdoors.

したがって、ケース７については防水構造にする必要性が低いことから、ボディ１とカバー２の継ぎ目部分を突合せ構造としたり（図４（ｅ）参照）、板厚方向において分割構造（図４（ｆ）参照）とするのが一般的であった。また、ボディ１とカバー２の継ぎ目部分の構造を板厚内で嵌合可能な鍵型構造とする場合もあった。   Therefore, since it is not necessary to make the case 7 waterproof, the joint portion of the body 1 and the cover 2 has a butted structure (see FIG. 4 (e)) or is divided in the thickness direction (FIG. 4 (f) ))). In some cases, the structure of the joint portion of the body 1 and the cover 2 is a key structure that can be fitted within the plate thickness.

しかしながら、例えば雨漏りや屋外ボックスの防水構造が不十分であることからケース７に水が掛かった場合には、上記の継ぎ目部分からケース７内部に水が侵入し、電子回路８が故障する虞があった。   However, for example, when the case 7 is splashed with water due to rain leaks or the waterproof structure of the outdoor box is insufficient, there is a risk that the water will enter the case 7 from the joint and the electronic circuit 8 may break down. there were.

そこで、上記の問題を解決するために、ボディ１とカバー２の継ぎ目部分にパッキンを施すことが考えられるが、この場合、パッキンによってケース７内部への水の侵入は防止できるものの、コストアップになるものであった。   Therefore, in order to solve the above problem, it is conceivable to seal the joint portion of the body 1 and the cover 2. In this case, although the packing can prevent water from entering the inside of the case 7, it increases the cost. It was.

また、前面側が開口する矩形箱状のケース本体と、後面側が開口し、ケース本体に上側から装着されるカバーとで構成された電子機器ケースも提案されている（例えば特許文献１参照）。この電子機器ケースでは、ケース本体の上面及び左右両側面に凸部が連続して設けられており、一方、カバーの内側面には上記の凸部と嵌合する凹部が連続して設けられている。そして、ケース本体に上側からカバーを装着させることで凸部と凹部とが互いに嵌合し、この嵌合構造によってケース本体内外が遮断される。つまり、上記の嵌合構造によって防水性が確保されるのである。   There has also been proposed an electronic device case composed of a rectangular box-shaped case main body that opens on the front side and a cover that opens on the rear side and is attached to the case main body from above (see, for example, Patent Document 1). In this electronic device case, convex portions are continuously provided on the upper surface and both left and right side surfaces of the case body, while concave portions that fit the convex portions are continuously provided on the inner side surface of the cover. Yes. And a convex part and a recessed part are mutually fitted by attaching a cover to a case main body from the upper side, and the inside and outside of a case main body are interrupted | blocked by this fitting structure. That is, waterproofness is ensured by the fitting structure.

上述の特許文献１に示した電子機器ケースでは、凸部と凹部による嵌合構造によって防水性は確保できるものの、ケース本体とカバーとの間に後面側から侵入してきた雨水を排水するためのスペースが必要であることからカバーが大型化し、その結果、電子機器ケースの大型化を招いていた。   In the electronic device case shown in the above-mentioned Patent Document 1, the waterproof structure can be secured by the fitting structure with the convex portion and the concave portion, but a space for draining rainwater that has entered from the rear side between the case main body and the cover. Therefore, the size of the cover has increased, and as a result, the size of the electronic device case has been increased.

本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、コストアップを抑えつつ簡単な構造により防水性を具備させた小型の電子機器のケースを提供することにある。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a case of a small electronic device having a waterproof structure with a simple structure while suppressing an increase in cost. .

本発明の電子機器のケースは、前面側に開口部を有する箱状のボディと、開口部を閉塞するようにしてボディに組み付けられるカバーとを備え、ボディ又はカバーの何れか一方には、他方側に向かって突出し、組付状態において他方の内周面に全周に亘って当接するリブが設けられており、少なくとも施工状態における上側のリブにおいて他方の内周面と対向する部位に溝部が設けられていることを特徴とする。   The case of the electronic device of the present invention includes a box-shaped body having an opening on the front side, and a cover that is assembled to the body so as to close the opening, and either the body or the cover has the other A rib that protrudes toward the side and abuts the other inner peripheral surface over the entire circumference in the assembled state, and a groove portion is provided at a position facing the other inner peripheral surface at least in the upper rib in the construction state. It is provided.

この電子機器のケースにおいて、溝部がリブの全周に亘って設けられているのが好ましい。   In the case of this electronic device, it is preferable that the groove is provided over the entire circumference of the rib.

In particular, when the groove 2j is provided over the entire circumference of the rib 2h as in the present embodiment, the water is laterally moved along the groove 2j even when the amount of water entering from the joint portion increases. As a result, there is an advantage that waterproofness can be improved. In addition, since the waterproof property can be secured with the simple structure of the groove portion 2j, the cost increase can be suppressed as compared with the case where packing is applied as in the conventional example.

また、本実施形態のようにボディ１とカバー２を突き合わせる構造とし、ボディ１に対してカバー２を位置決めするリブ２ｈに防水性を確保するための溝部２ｊを設けているので、上述した特許文献１の電子機器ケースに比べてケースの大型化を抑えることができ、その結果、小型の電子機器のケースを提供することができる。さらに、リブ２ｈの全周に亘って溝部２ｊを設けることによって、ボディ１及びカバー２の施工方向に関わらず防水性を確保することができる。また、ボディ１とカバー２の継ぎ目部分の近傍に溝部２ｊを設けているため、防水効果の高い電子機器のケースを提供することができる。   Further, since the body 1 and the cover 2 are abutted as in the present embodiment, and the groove 2j for securing the waterproof property is provided in the rib 2h for positioning the cover 2 with respect to the body 1, the above-described patent Compared to the electronic device case described in Document 1, the case can be prevented from being enlarged, and as a result, a small electronic device case can be provided. Furthermore, by providing the groove 2j over the entire circumference of the rib 2h, waterproofness can be ensured regardless of the construction direction of the body 1 and the cover 2. Moreover, since the groove part 2j is provided in the vicinity of the joint part of the body 1 and the cover 2, the case of an electronic device with a high waterproof effect can be provided.

次に、本実施形態の電子機器の組立手順について説明する。まず最初に、厚み方向が左右方向となるように配置した状態でプリント基板５，６をボディ１内に収納するとともに、厚み方向が前後方向となるように配置した状態でプリント基板４をボディ１内に収納する。その後、カバー２の各嵌合突起２ｋをボディ１の対応する嵌合孔１ｃにそれぞれ嵌合させてカバー２をボディ１に組み付ける（図１（ｄ）に示す状態）。そして最後に、蓋体３の各嵌合突起３ａをボディ１の対応する嵌合部１ｂにそれぞれ嵌合させて蓋体３をボディ１に組み付けると、電子機器の組み立てが完了する（図１（ａ）〜図１（ｃ）に示す状態）。   Next, a procedure for assembling the electronic device of this embodiment will be described. First, the printed circuit boards 5 and 6 are stored in the body 1 in a state where the thickness direction is the left-right direction, and the printed circuit board 4 is disposed in the state where the thickness direction is the front-rear direction. Store inside. Thereafter, each fitting protrusion 2k of the cover 2 is fitted into the corresponding fitting hole 1c of the body 1, and the cover 2 is assembled to the body 1 (state shown in FIG. 1 (d)). Finally, when each fitting protrusion 3a of the lid 3 is fitted to the corresponding fitting portion 1b of the body 1 and the lid 3 is assembled to the body 1, the assembly of the electronic device is completed (FIG. 1 ( a) to the state shown in FIG.

ここにおいて、本実施形態では、溝部２ｊをリブ２ｈの全周に亘って設けているが、少なくとも施工状態における上側のリブ２ｈに溝部２ｊが設けてあればよい。この場合、本実施形態と同様に、ボディ１とカバー２の継ぎ目部分から侵入した水を溝部２ｊに溜めることができるため、ボディ１内部への水の侵入を抑えて防水性を確保することができる。   Here, in this embodiment, although the groove part 2j is provided over the perimeter of the rib 2h, the groove part 2j should just be provided in the rib 2h of the upper side in a construction state at least. In this case, as in the present embodiment, water that has entered from the joint between the body 1 and the cover 2 can be stored in the groove 2j, so that water can be prevented from entering the inside of the body 1 to ensure waterproofness. it can.

また、本実施形態では、リブ２ｈをカバー２側に設けているが、ボディ１側にリブを設けてもよく、この場合にもリブに溝部を設けることで同様にコストアップを抑えつつ防水性を確保することができる。さらに、本実施形態では、ケース７内に収納される電子機器が電子式電力量計である場合について説明したが、電子機器は電子式電力量計に限定されるものではなく、他のものでもよい。   In the present embodiment, the rib 2h is provided on the cover 2 side. However, the rib may be provided on the body 1 side, and in this case as well, by providing a groove on the rib, waterproofing is similarly performed while suppressing cost increase. Can be secured. Furthermore, in this embodiment, although the case where the electronic device accommodated in case 7 was an electronic watt-hour meter was demonstrated, an electronic device is not limited to an electronic watt-hour meter, Other things may be used. Good.

また、本実施形態では、カバー２の嵌合突起２ｋが嵌合する嵌合孔１ｃがボディ１に設けられているため、嵌合孔１ｃからボディ１内部に水が侵入する可能性がある。したがって、カバー２の嵌合突起２ｋが嵌合する嵌合部をボディ１の両側壁及び底壁を貫通しないように設けることで上記の可能性をなくすことができ、さらに防水性を向上させることができる。   Moreover, in this embodiment, since the fitting hole 1c which the fitting protrusion 2k of the cover 2 fits is provided in the body 1, water may penetrate | invade into the inside of the body 1 from the fitting hole 1c. Therefore, the above-mentioned possibility can be eliminated by providing the fitting portion into which the fitting protrusion 2k of the cover 2 is fitted so as not to penetrate the both side walls and the bottom wall of the body 1, and further improve the waterproof property. Can do.
