Description

【０００１】
【発明の属する技術分野】
本発明は、屋外に設置される電子機器の筐体ケースに関し、例えば屋内向けＣＡＴＶ用電子機器を屋外に設置する際に用いられる防水ケースに関する。
【０００２】
【従来の技術】
従来、屋外に設置されるＣＡＴＶ用電子機器の防水ケースとしては、例えば図７に示される構造のものが知られている。
図７に示されるようにケース２００は、図略の電子機器が収納固定される本体ケース４０と電子機器を覆うカバー４１とが、ヒンジ機構４３により開閉自在に設けられ、留め具４４により本体ケース４０とカバー４１とが閉状態に固定される構造としている。このケース２００では、その下端に突出して設けられた円筒状の取出部４２により電子機器に設けられた端子や電源線を外部に導出している。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来技術では、各取出部４２においてスポンジ、ゴムなどのパッキンを用いて電源線などを挟み込むと共に、本体ケース４０とカバー４１との接合面などにもパッキンを配置することによって、ケース２００を防水しているので、部品点数が多くなり、コストが増加するという問題がある。又、取出部４２が下端に突出して設けられることにより、その分だけケース２００が大型化し、この点においてもコストの増加をもたらすという問題がある。
【０００４】
従って、本発明の目的は、上記課題に鑑み、電子機器の筐体ケースにおいて、防水性を確保しつつ、小型化及び低価格化を実現することである。
【０００５】
【課題を解決するための手段】
上記の課題を解決するために、請求項１に記載の手段によれば、屋外に設置される電子機器の筐体ケースは、基台とカバーとで構成される。基台は、電子機器に設けられた端子を鉛直下側に取出すための孔が形成された端子取出面と、その端子取出面に対して略垂設され、所定位置への取付けに用いられる取付面とを有しており、この基台に電子機器が固定される。カバーは、基台と係止されることにより電子機器を覆い、端子取出面より鉛直下側に所定長だけ突出した裾部を有している。そして、端子取出面の縁部に、電子機器の電源線を外部に導出するための、第１側壁と第２側壁とを有する略Ｕ字状断面の溝部が内側に所定の長さを有して形成される。
これにより、端子取出面の縁部において内側に向かって設けられた溝部に電源線を配置し、カバーの裾部が端子取出面に対して所定長だけ鉛直下側に突出して設けられるので、溝部に対して十分な防水性を得ることができる。又、電源線を略Ｕ字状断面の溝部に配置する構成であるので、組付けが容易である。又、溝部に対する防水性を得るために、パッキンを必要としないので部品点数を低減できる。又、電源線を導出する溝部が内側に設けられているので、ケースの小型化が可能となり、コストを低減できる。
【０００６】
請求項２に記載の手段によれば、端子取出面側における溝部の深さ及び幅を、電源線の外径寸法に略等しくすることにより、電源線と第１側壁及び第２側壁との間の間隙がなくなり、ケースの防水性をより高めることができる。
【０００７】
請求項３に記載の手段によれば、第１側壁及び第２側壁のうち、少なくとも電子機器側に位置する側壁の一辺が端子取出面に設けられ、他の一辺が取付面上に設けられることにより、その側壁が電子機器と電源線との間を仕切る隔壁を構成する。溝部からケース内部に水が浸入したとしても、取付面まで延びた隔壁により電子機器側への浸入が防止されるので、電子機器に対する水の浸入をより効果的に防止できる。
【０００８】
【発明の実施の形態】
以下、本発明を具体的な実施例に基づいて説明する。
図１は、本発明の具体的な実施例に係わる筐体ケース１００の構成を示した模式図である。ケース１００は、ＡＢＳ（アクリロニトリル−ブタジエン−スチレン）などの硬質樹脂から成り、基台１０とカバー２０とで構成されている。基台１０は、壁面等への取付けのために取付孔１１、１２が設けられた取付面２と、その取付面２に対して略垂設された端子取出面１とで構成されている。
端子取出面１には、後述するＣＡＴＶ用増幅器のアース端子、入力端子、モニター端子及び出力端子をそれぞれ外部に導出するために、孔６、７、８及び９とが形成されている。又、増幅器の電源線を外部に導出するために、端子取出面１の縁部１ａに略Ｕ字状の切欠き３が形成されている。この切欠き３の深さ及び幅は、電源線の外径寸法に略等しく形成されている。端子取出面１の内側の切欠き３の側壁３ａ近傍には、所定長さを有する第１側壁４及び第２側壁５が設けられている。この第１側壁４及び第２側壁５の一辺は端子取出面１に接合され、他の一辺は取付面２上に接合され、端子取出面１及び取付面２に対して略垂設されている。第１側壁４及び第２側壁５は、切欠き３側より取付面２側が長い台形状を成している。ここで、切欠き３、第１側壁４及び第２側壁５が請求項でいう溝部に相当し、第１側壁４が増幅器と電源線とを仕切る隔壁に相当する。
カバー２０は、基台１０の端子取出面１に対応した開口部を有した略箱状を成し、正面部２０ａの内壁には基台１０との係止に用いられる係止部２２（図３参照）が設けられている。又、正面部２０ａと側面部２０ｂ、２０ｃには、基台１０との係止時に増幅器の端子や電源線を覆うことにより、それらに対して防水効果を与える裾部２１ａ、２１ｂ及び２１ｃがそれぞれ設けられている。
【０００９】
次に、増幅器３０のケース１００への取付け方法について図２及び図３を用いて説明する。まず、増幅器３０を基台１０の取付面２上に載置し、入力端子３４、モニタ端子３５及び出力端子３６をそれぞれ孔７、８及び９に挿入し、端子取出面１と増幅器３０の対向する面とを当接させる。尚、入力端子３４、モニタ端子３５及び出力端子３６は、それぞれ図略のゴムブーツを備えた同軸ケーブルに接続されるので、これら端子については良好な防水性が得られる。
次に、アース端子３２の孔にネジ３３を挿通し、このネジ３３を孔６を介して増幅器３０のネジ孔（図略）に螺着する。このネジ３３のネジ孔への螺着により、増幅器３０が基台１０に固定される。又、増幅器３０のケースがこのアース端子３２に電気的に接続される。増幅器３０の側面部より導出された100Vの電源線３１は、第１側壁４と第２側壁５との間に配置され、切欠き３より端子取出面１の外側に導出される。基台１０に増幅器３０を取付けた状態を示した斜視図が図２である。
【００１０】
増幅器３０を基台１０に固定した後、カバー２０を基台１０に対して図１に示される位置関係に配置し、カバー２０を基台１０側にスライドさせることにより、カバー２０を基台１０に組付ける。
カバー２０の正面部２０ａに設けられた係止部２２が、端子取出面１の縁部１ａに係止することにより、カバー２０と基台１０とが組付けられる。図３は、この状態を示した模式的断面図であり、図の縦方向が壁面方向である。尚、図３は、切欠き３を通って取付面２に対して直交する面を切断面とした第２側壁５側から見た図である。図３に示されるように、カバー２０の裾部２１ａ、２１ｂ及び２１ｃが端子取出面１より所定長だけ下側に突出して設けられる。カバー２０の取り外しは、裾部２１ａに対して端子取出面１より離れる方向に力を作用させ、係止部２２と縁部１ａとの係止を解除して、カバー２０を上方にスライドさせればよい。
【００１１】
上記に示すように、切欠き３が端子取出面１の縁部１ａに設けられ、切欠き３の深さ及び幅が電源線３１の外径に略等しく、カバー２０の裾部２１ａ〜２１ｃが所定長だけ下側に突出しているので、切欠き３からケース１００内に雨水が浸入することがなく、鉛直から６０度の角度範囲（ＪＩＳ保護等級３）内で進行する雨水に対して良好な防水性が得られる。
又、仮に切欠き３よりケース１００内に水が浸入したとしても、第１側壁４が電源線３１と増幅器３０とを仕切る隔壁として機能するので、増幅器３０に対して確実に防水できる。又、第１側壁４と第２側壁５の長さのため、切欠き３より水が浸入しても第１側壁４と増幅器３０との間に浸入せずに、重力により切欠き３より外部に排出されるので良好な排水性が得られる。
又、電源線３１の組付けの際に、第１側壁４と第２側壁５とがガイドとして機能するので、電源線３１の組付けが容易である。又、本実施例では、防水性を得るために、切欠き３と電源線３１との間にゴム等のパッキンを設ける必要がないので、ケース１００の部品点数が低減し、コストを低減できる。さらに、第１隔壁４及び第２隔壁５をケース１００の内部に設けているので、ケース１００の小型化が可能であり、コストをより低減できる。
【００１２】
上記実施例では、略台形状の第１側壁４及び第２側壁５の他端を取付面２上に接合したが、電源線３１と増幅器３０との間を仕切る隔壁が設けられればよいので、第２側壁５の他端は必ずしも取付面２上に接合しなくともよい。
又、カバー２０の裾部２１ａ〜２１ｃによる防水効果が十分であれば、電源線３１と増幅器３０との間を仕切る隔壁がなくともよい。隔壁を設けない基台６０の斜視図を図４に示すが、略Ｕ字状の切欠き３の側壁３ａの近傍に、所定長の側壁５１、５２から成る略Ｕ字状断面の溝５０が、縁部１ａの内側に突出して接合されている。この基台６０では、増幅器側に設けられた側壁５１は取付面２に接合されず、電源線と増幅器との間を仕切る隔壁が設けられていない。このように、カバー２０の裾部２１ａ〜２１ｃによる防水効果が十分であれば、基台６０に隔壁を設けない構成としてもよい。
又、上記実施例では、切欠き３の深さ及び幅を電源線３１の外径寸法に略等しくすることにより防水性を高めているが、電源線３１の外径寸法と略等しくする部位は切欠き３に限定されるものではない。例えば、図４に示す構成において、溝５０の深さ及び幅を長手方向に沿って変化させ、溝５０の長手方向の切欠き３側の所定の位置において、溝５０の深さ及び幅を電源線の外径寸法に略等しくすれば、切欠き３の深さ及び幅を電源線３１の外径寸法に略等しくせずとも、上記実施例と同等の防水性を得ることが可能である。
【００１３】
又、上記実施例では、カバー２０の正面部２０ａに対向した端子取出面１の縁部１ａに設けた切欠き３より電源線３１を取出す構成としたが、電源線３１を端子取出面１の他の縁部より取出す構成としてもよい。例えば、図５に示されるように、カバー２０の側面部２０ｃに対向した端子取出面１の縁部１ｃに溝７０を設け、その溝７０より電源線３１を取出してもよい。又、図５に示されるように、溝７０の端面７０ａを、端子取出面１より外側に突出して設けてもよい。
【００１４】
又、取付面２を用いて電源線３１を取出すための溝を構成してもよい。その構成を図６に示す。図６に示されるように、基台１１０の端子取出面１の大きさは増幅器３０のサイズと略同等の大きさを成しており、図１に示される基台１０に比べて小さく形成されている。端子取出面１の縁部１ｃには、端子取出面１及び取付面２に略直交して第１側壁８１が設けられている。この第１側壁８１の深さは端子取出面１の縁部１ｃに略等しく、縁部１ｃと異なる側の端部８１ａは取付面２の端部２ａに至るだけの長さを有せず、端部８１ａと端部２ａとの間の空間で電源線３１の配置を可能としている。この第１側壁８１に対して所定間隔を隔てて、取付面２上に第２側壁８２が設けられている。第２側壁８２の深さは上述の電源線３１の外径寸法に略等しい。第１側壁８１、第２側壁８２及びそれらの間の取付面２の部分で、溝８０が構成されている。カバー１２０は、溝８０に応じた形状の凸部１２１が設けられており、図１に示されるカバー２０に比べて小さい形状となっている。このように、基台１１０とカバー１２０とでケース１０１を構成することで、上記実施例と同等の防水性が得られると共に、ケース１０１をより小型化することが可能である。
又、上記実施例では、本発明を増幅器３０に適用した例について説明したが、本発明は、屋外に設置される全ての電子機器に対して適用可能である。

BACKGROUND OF THE INVENTION
The present invention relates to a housing case of an electronic device installed outdoors, for example, a waterproof case used when an indoor CATV electronic device is installed outdoors.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a waterproof case for CATV electronic equipment installed outdoors, for example, the structure shown in FIG. 7 is known.
As shown in FIG. 7, the case 200 is provided with a body case 40 in which an unillustrated electronic device is housed and fixed, and a cover 41 covering the electronic device, which can be opened and closed by a hinge mechanism 43. 40 and the cover 41 are fixed in a closed state. In this case 200, a terminal and a power supply line provided in the electronic device are led out to the outside by a cylindrical extraction portion 42 provided so as to protrude from the lower end thereof.
[0003]
[Problems to be solved by the invention]
However, in the above-described prior art, the power supply line or the like is sandwiched between each extraction portion 42 using a packing such as sponge or rubber, and the packing is also disposed on the joint surface between the main body case 40 and the cover 41, thereby providing the case 200. Since this is waterproof, there is a problem that the number of parts increases and the cost increases. Further, since the take-out portion 42 is provided so as to protrude from the lower end, there is a problem that the case 200 is increased in size by that amount, and this also causes an increase in cost.
[0004]
Therefore, in view of the above problems, an object of the present invention is to achieve downsizing and cost reduction while ensuring waterproofness in a housing case of an electronic device.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problem, according to the means described in claim 1, a housing case of an electronic device installed outdoors includes a base and a cover. The base is a terminal extraction surface in which a hole for taking out a terminal provided in the electronic device vertically is formed, and an installation that is substantially perpendicular to the terminal extraction surface and is used for attachment to a predetermined position. The electronic device is fixed to the base. The cover covers the electronic device by being locked with the base, and has a skirt that protrudes a predetermined length vertically below the terminal extraction surface. And the groove part of the substantially U-shaped cross section which has the 1st side wall and the 2nd side wall for deriving the power supply line of an electronic device outside to the edge part of a terminal extraction surface has predetermined length inside. Formed.
As a result, the power line is arranged in the groove portion provided inward at the edge of the terminal extraction surface, and the skirt portion of the cover is provided so as to protrude vertically downward from the terminal extraction surface by a predetermined length. Sufficient waterproofness can be obtained. Further, since the power supply line is arranged in the groove portion having a substantially U-shaped cross section, the assembly is easy. In addition, in order to obtain waterproofness for the groove portion, no packing is required, so the number of parts can be reduced. Further, since the groove portion for leading the power supply line is provided on the inner side, the case can be miniaturized and the cost can be reduced.
[0006]
According to the second aspect of the present invention, the depth and width of the groove on the terminal lead-out surface side are made substantially equal to the outer diameter of the power supply line, so that the gap between the power supply line and the first and second side walls is increased. This eliminates the gap and improves the waterproofness of the case.
[0007]
According to the means of claim 3, at least one side of the first side wall and the second side wall located on the electronic device side is provided on the terminal extraction surface, and the other side is provided on the mounting surface. Therefore, the side wall forms a partition that partitions the electronic device and the power supply line. Even if water enters the inside of the case from the groove portion, the partition wall extending to the mounting surface prevents the entry to the electronic device side, so that the water can be more effectively prevented from entering the electronic device.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on specific examples.
FIG. 1 is a schematic diagram showing a configuration of a housing case 100 according to a specific embodiment of the present invention. The case 100 is made of a hard resin such as ABS (acrylonitrile-butadiene-styrene), and includes a base 10 and a cover 20. The base 10 includes an attachment surface 2 provided with attachment holes 11 and 12 for attachment to a wall surface and the like, and a terminal extraction surface 1 that is substantially suspended from the attachment surface 2.
Holes 6, 7, 8, and 9 are formed in the terminal extraction surface 1 to lead out a ground terminal, an input terminal, a monitor terminal, and an output terminal of a CATV amplifier, which will be described later, to the outside. In addition, a substantially U-shaped notch 3 is formed in the edge portion 1a of the terminal extraction surface 1 in order to lead out the power supply line of the amplifier. The depth and width of the notch 3 are formed approximately equal to the outer diameter of the power supply line. A first side wall 4 and a second side wall 5 having a predetermined length are provided in the vicinity of the side wall 3 a of the notch 3 inside the terminal extraction surface 1. One side of the first side wall 4 and the second side wall 5 is joined to the terminal extraction surface 1, and the other side is joined to the attachment surface 2, and is substantially perpendicular to the terminal extraction surface 1 and the attachment surface 2. . The first side wall 4 and the second side wall 5 have a trapezoidal shape in which the attachment surface 2 side is longer than the notch 3 side. Here, the notch 3, the first side wall 4, and the second side wall 5 correspond to a groove portion in the claims, and the first side wall 4 corresponds to a partition wall that partitions the amplifier and the power supply line.
The cover 20 has a substantially box shape having an opening corresponding to the terminal extraction surface 1 of the base 10, and a locking portion 22 (see FIG. 5) used for locking with the base 10 on the inner wall of the front portion 20 a. 3). Further, the front portion 20a and the side portions 20b and 20c are provided with skirt portions 21a, 21b and 21c which provide a waterproof effect to the amplifier terminals and power lines when they are locked to the base 10, respectively. Is provided.
[0009]
Next, a method for attaching the amplifier 30 to the case 100 will be described with reference to FIGS. First, the amplifier 30 is placed on the mounting surface 2 of the base 10, and the input terminal 34, the monitor terminal 35 and the output terminal 36 are inserted into the holes 7, 8 and 9, respectively. The surface to be touched is brought into contact. In addition, since the input terminal 34, the monitor terminal 35, and the output terminal 36 are each connected to the coaxial cable provided with the rubber boot which is not illustrated, favorable waterproofness is obtained about these terminals.
Next, the screw 33 is inserted into the hole of the ground terminal 32, and the screw 33 is screwed into the screw hole (not shown) of the amplifier 30 through the hole 6. The amplifier 30 is fixed to the base 10 by screwing the screw 33 into the screw hole. The case of the amplifier 30 is electrically connected to the ground terminal 32. The 100 V power supply line 31 led out from the side surface of the amplifier 30 is arranged between the first side wall 4 and the second side wall 5 and led out of the terminal extraction surface 1 from the notch 3. FIG. 2 is a perspective view showing a state where the amplifier 30 is attached to the base 10.
[0010]
After the amplifier 30 is fixed to the base 10, the cover 20 is arranged in the positional relationship shown in FIG. 1 with respect to the base 10, and the cover 20 is slid toward the base 10, whereby the cover 20 is fixed to the base 10. Assemble to.
The cover 20 and the base 10 are assembled by the locking portion 22 provided on the front portion 20 a of the cover 20 being locked to the edge portion 1 a of the terminal extraction surface 1. FIG. 3 is a schematic cross-sectional view showing this state, in which the vertical direction is the wall surface direction. FIG. 3 is a view seen from the second side wall 5 side, with a surface passing through the notch 3 and orthogonal to the mounting surface 2 as a cut surface. As shown in FIG. 3, the skirts 21 a, 21 b, and 21 c of the cover 20 are provided so as to protrude downward from the terminal extraction surface 1 by a predetermined length. The cover 20 can be removed by applying a force in a direction away from the terminal extraction surface 1 to the skirt portion 21a, releasing the locking between the locking portion 22 and the edge 1a, and sliding the cover 20 upward. That's fine
[0011]
As described above, the notch 3 is provided in the edge 1a of the terminal extraction surface 1, the depth and width of the notch 3 are substantially equal to the outer diameter of the power line 31, and the skirts 21a to 21c of the cover 20 are Since it protrudes downward by a predetermined length, rainwater does not enter the case 100 from the notch 3 and is good for rainwater traveling within an angle range of 60 degrees from the vertical (JIS protection class 3). Waterproofness is obtained.
Even if water enters the case 100 from the notch 3, the first side wall 4 functions as a partition wall that partitions the power supply line 31 and the amplifier 30, so that the amplifier 30 can be reliably waterproofed. In addition, because of the length of the first side wall 4 and the second side wall 5, even if water enters from the notch 3, it does not enter between the first side wall 4 and the amplifier 30, but the outside from the notch 3 by gravity. Good drainage can be obtained.
Further, when the power supply line 31 is assembled, the first side wall 4 and the second side wall 5 function as a guide, so that the power supply line 31 can be easily assembled. Further, in this embodiment, it is not necessary to provide a packing such as rubber between the notch 3 and the power supply line 31 in order to obtain waterproofness, so that the number of parts of the case 100 can be reduced and the cost can be reduced. Furthermore, since the first partition 4 and the second partition 5 are provided inside the case 100, the case 100 can be reduced in size and the cost can be further reduced.
[0012]
In the above embodiment, the other ends of the substantially trapezoidal first side wall 4 and the second side wall 5 are joined on the mounting surface 2, but a partition wall for partitioning between the power line 31 and the amplifier 30 may be provided. The other end of the second side wall 5 does not necessarily have to be joined to the mounting surface 2.
Further, if the waterproof effect by the skirt portions 21 a to 21 c of the cover 20 is sufficient, there may be no partition wall that partitions the power line 31 and the amplifier 30. FIG. 4 shows a perspective view of the base 60 not provided with a partition wall. A groove 50 having a substantially U-shaped cross section including side walls 51 and 52 having a predetermined length is provided in the vicinity of the side wall 3a of the substantially U-shaped notch 3. , Protruding and joined to the inside of the edge 1a. In this base 60, the side wall 51 provided on the amplifier side is not joined to the mounting surface 2, and no partition wall is provided between the power supply line and the amplifier. Thus, if the waterproof effect by the skirt parts 21a-21c of the cover 20 is sufficient, it is good also as a structure which does not provide a partition in the base 60. FIG.
In the above embodiment, the depth and width of the notch 3 are made substantially equal to the outer diameter of the power supply line 31 to improve the waterproof property. It is not limited to the notch 3. For example, in the configuration shown in FIG. 4, the depth and width of the groove 50 are changed along the longitudinal direction, and the depth and width of the groove 50 are changed to a predetermined position on the notch 3 side in the longitudinal direction of the groove 50. If the outer diameter dimension of the wire is made substantially equal, the depth and width of the notch 3 can be made waterproof equivalent to the above-described embodiment without making the depth and width of the notch 3 substantially equal to the outer diameter dimension of the power line 31.
[0013]
Moreover, in the said Example, although it was set as the structure which takes out the power wire 31 from the notch 3 provided in the edge part 1a of the terminal extraction surface 1 facing the front part 20a of the cover 20, the power supply wire 31 of the terminal extraction surface 1 is used. It is good also as a structure taken out from another edge part. For example, as shown in FIG. 5, a groove 70 may be provided in the edge portion 1 c of the terminal extraction surface 1 facing the side surface portion 20 c of the cover 20, and the power supply line 31 may be taken out from the groove 70. Further, as shown in FIG. 5, the end surface 70 a of the groove 70 may be provided so as to protrude outward from the terminal extraction surface 1.
[0014]
Moreover, you may comprise the groove | channel for taking out the power wire 31 using the attachment surface 2. FIG. The configuration is shown in FIG. As shown in FIG. 6, the size of the terminal extraction surface 1 of the base 110 is substantially the same as the size of the amplifier 30 and is formed smaller than the base 10 shown in FIG. ing. A first side wall 81 is provided at the edge 1 c of the terminal extraction surface 1 so as to be substantially orthogonal to the terminal extraction surface 1 and the mounting surface 2. The depth of the first side wall 81 is substantially equal to the edge 1c of the terminal extraction surface 1, and the end 81a on the side different from the edge 1c does not have a length that reaches the end 2a of the mounting surface 2. The power line 31 can be arranged in the space between the end portion 81a and the end portion 2a. A second side wall 82 is provided on the mounting surface 2 at a predetermined interval from the first side wall 81. The depth of the second side wall 82 is substantially equal to the outer diameter of the power line 31 described above. A groove 80 is formed by the first side wall 81, the second side wall 82, and the portion of the mounting surface 2 between them. The cover 120 is provided with a convex portion 121 having a shape corresponding to the groove 80, and is smaller than the cover 20 shown in FIG. In this manner, by forming the case 101 with the base 110 and the cover 120, waterproofness equivalent to that of the above embodiment can be obtained, and the case 101 can be further downsized.
In the above embodiment, the example in which the present invention is applied to the amplifier 30 has been described. However, the present invention is applicable to all electronic devices installed outdoors.
