Abstract
Description
本発明は、メンテナンスカバー付き通信機器に係り、特に電子機器等においてメンテナンス時のみに使用するコネクタ類を覆うメンテナンスカバーの取り付け構造が改良されたメンテナンスカバー付き通信機器に関する。 The present invention relates to a communication device with a maintenance cover, and more particularly to a communication device with a maintenance cover in which an attachment structure of a maintenance cover that covers connectors used only for maintenance in an electronic device or the like is improved.
図１は、従来の通信機器の外観図である。図１の通信機器は具体的にはＩＭＴ−２０００用の中継増幅装置であって、角が取れた直方体状の筐体に収納されている。筐体は、最も長さの短い辺に対する略垂直面で略半分に分割可能となるように、２つの部材で構成されている。内部の機器本体を収納した上で、その両部材をボルトなどで締着し、箱状の筐体を成すようにしている。筐体の両部材は、鋳造や射出成形などで成型されるので、その天面、底面、及び両側面は、型抜き等の都合上、接合（開口）面側から離れるに従い幅が狭くなるようなテーパ面となっている。
また、筐体の天面側には、高周波同軸ケーブルや電源ケーブルのような太くて硬いケーブル類と接続するためのコネクタ等が設けられ、底面側には、その他のコネクタ類、スイッチ類が設けられている。
FIG. 1 is an external view of a conventional communication device. 1 is a relay amplification device for IMT-2000, and is housed in a rectangular parallelepiped housing having a rounded corner. The casing is composed of two members so that the casing can be divided substantially in half on a substantially vertical plane with respect to the shortest side. After housing the internal device body, both members are fastened with bolts or the like to form a box-shaped housing. Since both members of the casing are molded by casting, injection molding, etc., the top surface, bottom surface, and both side surfaces become narrower as they move away from the joining (opening) surface side for convenience of die cutting. It has a tapered surface.
In addition, connectors for connecting to thick and hard cables such as high-frequency coaxial cables and power cables are provided on the top side of the housing, and other connectors and switches are provided on the bottom side. It has been.
底面側に設けられたコネクタ類や設定スイッチ類には、運用開始時の初期設定、もしくは定期メンテナンス時、装置不具合時のメンテナンス時にのみ使用するものがあり、それらは通常運用時には一切使用しない。そのため、容易にアクセスして設定変更等ができない様に、それらコネクタ類、各種設定スイッチには、いたずら防止や異物混入保護の観点から、メンテナンスカバー（保護カバー）が取り付けられるのが一般的である。 Some connectors and setting switches provided on the bottom side are used only at the initial setting at the start of operation, or at the time of regular maintenance or maintenance at the time of malfunction of the device, and they are not used at all during normal operation. Therefore, a maintenance cover (protective cover) is generally attached to these connectors and various setting switches from the viewpoint of preventing tampering and protecting foreign matter so that settings cannot be easily accessed and changed. .
図２は、図１の通信機器の底面図（メンテナンスカバー装着時）であり、図３は、図１の通信機器の底面図（メンテナンスカバー非装着時）である。
１は筐体、２はメンテナンスカバー、３−１はメンテナンスカバー２の一端を筐体１に固定するネジ、３−２は他の一端を固定するネジ、４−１はメンテナンスカバー２の取り付け面から飛び出さない程度に筐体２の内部に備えられたメンテナンス用コネクタ、４−２は同様に筐体２の内部に備えられた設定スイッチである。
筐体１のメンテナンス用コネクタ４−１等の設けられる部分には、メンテナンスカバー２の取り付け面として、平坦な凹部（ザグリ）を形成し、凹部内に個々のメンテナンス用コネクタ４−１等のみが露出するような開口を穿設する。凹部はメンテナンスカバー２より若干大きな形状と、メンテナンスカバー２の厚さと同程度かそれ以上の深さを有しており、メンテナンスカバー２はその凹部に収められる。これにより筐体からの無用な突出がなくなり、外部の物体がぶつかることによるメンテナンスカバー２の損傷も防止できる。凹部の背面寄りの端は、筐体底面がテーパをなしているために、底面表面と段差がなくなっていてもよい。
メンテナンス時にメンテナンス用コネクタ４−１や設定スイッチ４−２にアクセスする場合、２本ある固定ネジ３−１、３−２の両方を完全に取り外す、もしくは、固定ネジ３−１のみ完全に取り外し、固定ネジ３−２を若干緩めて、メンテナンスカバー２を略９０度回転させる。
2 is a bottom view of the communication device of FIG. 1 (when a maintenance cover is attached), and FIG. 3 is a bottom view of the communication device of FIG. 1 (when a maintenance cover is not attached).
DESCRIPTION OF SYMBOLS 1 is a housing | casing, 2 is a maintenance cover, 3-1 is a screw which fixes the end of the maintenance cover 2 to the housing | casing 1, 3-2 is a screw which fixes the other end, 4-1 is a mounting surface of the maintenance cover 2 A maintenance connector provided in the interior of the housing 2 to the extent that it does not jump out of the housing 2, and 4-2 are setting switches provided in the interior of the housing 2.
A flat concave portion is formed as a mounting surface of the maintenance cover 2 in a portion where the maintenance connector 4-1 etc. of the housing 1 is provided, and only individual maintenance connectors 4-1 etc. are provided in the concave portion. Open an opening that will be exposed. The concave portion has a slightly larger shape than the maintenance cover 2 and has a depth equal to or greater than the thickness of the maintenance cover 2, and the maintenance cover 2 is accommodated in the concave portion. As a result, unnecessary protrusion from the casing is eliminated, and damage to the maintenance cover 2 due to collision with an external object can be prevented. Since the bottom surface of the housing is tapered, the step near the back surface of the recess may be free from a step difference from the bottom surface.
When accessing the maintenance connector 4-1 and the setting switch 4-2 during maintenance, remove both the two fixing screws 3-1 and 3-2 completely, or completely remove only the fixing screw 3-1. Loosen the fixing screw 3-2 and rotate the maintenance cover 2 by approximately 90 degrees.
図４は、従来の図１の通信機器のメンテナンスカバー２の外観図である。メンテナンスカバー２は、例えば略長方形の金属若しくは樹脂製の平板であり、両端部に固定ネジ３−１、３−２をそれぞれ通すための穴２−１、２−２が設けられている。
本例では、穴２−２とネジ３−２により筐体に接続された状態で回転可能になるように、メンテナンスカバー２の穴２−２側の一端は、穴２−２を中心する一定の半径で略半周に亘る面取りが施されている。
FIG. 4 is an external view of the maintenance cover 2 of the conventional communication device of FIG. The maintenance cover 2 is a substantially rectangular flat plate made of metal or resin, for example, and has holes 2-1 and 2-2 for passing the fixing screws 3-1 and 3-2 at both ends.
In this example, one end of the maintenance cover 2 on the side of the hole 2-2 is fixed around the hole 2-2 so as to be rotatable while being connected to the housing by the hole 2-2 and the screw 3-2. Chamfering is performed over a substantially half circumference with a radius of.
しかしながら従来の通信機器では、少なくても１個の固定ネジを完全に取り外す必要があること、また、作業性を考慮した場合は、２本の固定ネジとメンテナンスカバーを全て取り外さなければならないため、それらパーツを紛失する恐れがあった。特に、本装置が天井裏等の作業性が悪いエリアに設置されている場合、なおさらアクセスが困難となり、これらのパーツを紛失しやすくなる。
また、メンテナンス完了後に一度取り外した固定ネジ、メンテナンスカバーを取り付けなければならないが、その作業を忘れてそのまま運用開始しても、装置の設置方向によってはそれを発見するのが困難であった。
However, in conventional communication equipment, it is necessary to completely remove at least one fixing screw, and when considering workability, it is necessary to remove all two fixing screws and the maintenance cover. There was a risk of losing those parts. In particular, when the apparatus is installed in an area with poor workability such as a ceiling, access becomes more difficult, and these parts are easily lost.
In addition, it is necessary to attach the fixing screw and the maintenance cover once removed after the maintenance is completed, but even if the operation is forgotten and the operation is started as it is, it is difficult to find it depending on the installation direction of the apparatus.
本発明は上記実情に鑑みて為されたもので、わずかな形状変更により部品点数を増やすことなく、メンテナンスカバー等の紛失を防ぎ、メンテナンスカバーの戻し忘れを容易に発見することができるメンテナンスカバー付き通信機器を提供することを目的とする。 The present invention has been made in view of the above circumstances, and with a maintenance cover that can prevent the maintenance cover from being lost and easily detect forgetting to return the maintenance cover without increasing the number of parts by slightly changing the shape.

以下本発明を実施例を通じて図面を参照しながら説明するが、実施例で説明する構成の全ての組み合わせが本発明に必須であるとは限らない。また各実施例の特徴の任意の組み合わせや、引用した従来技術との組み合わせも本発明に含まれうる。 Hereinafter, the present invention will be described through examples with reference to the drawings. However, all combinations of configurations described in the examples are not necessarily essential to the present invention. Further, any combination of the features of each embodiment and a combination with the cited prior art can be included in the present invention.
図５は本実施例のメンテナンスカバー付き通信機器の外観図、図６はその底面図（メンテナンスカバー閉鎖時）である。
筐体５は、メンテナンスカバー６の取り付け面における構成を除き、従来の筐体１と同じである。具体的には、取り付け面を構成する凹部が、メンテナンスカバー６の形状にあわせて拡大されている。
メンテナンスカバー６は、略長方形状の平板であり、その向かい合う二辺にそれぞれ沿って長穴（６−１、６−２）を有している。詳細は後述する。
窓６−３は、メンテナンスカバーに略長方形状に設けられ、メンテナンスカバー６を長穴（６−１、６−２）の長さ分いっぱいまでスライドしたとき（メンテナンス位置）に、メンテナンス用コネクタ（１０−１）や設定スイッチ（１０−２）が従来と同様に必要なだけ露出するように、開口の大きさ及び位置が設計されている。
FIG. 5 is an external view of a communication device with a maintenance cover according to this embodiment, and FIG. 6 is a bottom view thereof (when the maintenance cover is closed).
The casing 5 is the same as the conventional casing 1 except for the configuration on the attachment surface of the maintenance cover 6. Specifically, the concave portion constituting the attachment surface is enlarged in accordance with the shape of the maintenance cover 6.
The maintenance cover 6 is a substantially rectangular flat plate and has long holes (6-1, 6-2) along two opposite sides thereof. Details will be described later.
The window 6-3 is provided in a substantially rectangular shape on the maintenance cover. When the maintenance cover 6 is slid to the full length of the long holes (6-1, 6-2) (maintenance position), the maintenance connector ( 10-1) and the setting switch (10-2) are designed so that the opening size and position are exposed as much as necessary.
２本の固定ネジ７−１、７−２は、従来の固定ネジ３−１、３−２に相当し、メンテナンスカバー６の長穴（６−１、６−２）にそれぞれ通して筐体５にねじ込まれ、それによりメンテナンスカバー６をスライド可能なように筐体５に繋ぎ止める。
開け方向指示表記９は、筐体５の凹部に印刷あるいは刻印されたメンテナンスカバー６のスライド方向を指示する表記であり、メンテナンスカバー６を通常時の位置（メンテナンス用コネクタ（１０−１）等がカバーされた位置）にしたときに窓６−３から露出する領域に設けられているこれにより、メンテナンス時のメンテナンスカバー６のスライド方向が容易に分かる。
The two fixing screws 7-1 and 7-2 correspond to the conventional fixing screws 3-1 and 3-2, and pass through the long holes (6-1 and 6-2) of the maintenance cover 6, respectively. Then, the maintenance cover 6 is fixed to the housing 5 so as to be slidable.
The opening direction indication notation 9 is an indication for instructing the sliding direction of the maintenance cover 6 printed or engraved on the concave portion of the housing 5, and the maintenance cover 6 is moved to a normal position (maintenance connector (10-1) or the like). Thus, the sliding direction of the maintenance cover 6 during maintenance can be easily understood.
図７は、本実施例のメンテナンスカバー付き通信機器の底面図（メンテナンスカバー開放時）である。
メンテナンス用コネクタ１０−１、設定スイッチ１０−２は、従来のメンテナンス用コネクタ４−１、設定スイッチ４−２と同一である。これらは通常プリント配線板上に実装されるので、窓８の長手方向にほぼ直線状に配置されることになる。
FIG. 7 is a bottom view of the communication device with a maintenance cover according to the present embodiment (when the maintenance cover is opened).
The maintenance connector 10-1 and the setting switch 10-2 are the same as the conventional maintenance connector 4-1 and setting switch 4-2. Since these are usually mounted on a printed wiring board, they are arranged substantially linearly in the longitudinal direction of the window 8.
本実施例のメンテナンスカバー付き通信機器では、装置のメンテナンス時、もしくは初期設定時等にメンテナンスカバー６を開ける場合、固定ネジ７−１、７−２を緩めて、メンテナンスカバー６を開け方向指示表記９の示す方向（背面に向かう方向）にスライドさせることによって、メンテナンス用コネクタ１０−１、設定スイッチ１０−２に容易にアクセスすることができる。
つまり、固定ネジ２本、メンテナンスカバー共に、装置から取り外すことなく作業ができるため、それらパーツ類の紛失を防ぐことができる。
In the communication device with a maintenance cover of this embodiment, when the maintenance cover 6 is opened at the time of maintenance of the apparatus or at the initial setting, the fixing screws 7-1 and 7-2 are loosened, and the maintenance cover 6 is opened and the direction indication is indicated. By sliding in the direction indicated by 9 (the direction toward the back), the maintenance connector 10-1 and the setting switch 10-2 can be easily accessed.
That is, since both the two fixing screws and the maintenance cover can be operated without being removed from the apparatus, the loss of these parts can be prevented.
図８は、本実施例のメンテナンスカバー６の詳細図である。
長穴６−１、６−２は、互いに略平行となるようにメンテナンスカバー６に穿設される。長穴６−１、６−２の長さは、スライド長を決定するので、少なくとも筐体の穴及びメンテナンスカバー６の窓６−３のいずれの幅よりも長い。
窓６−３は、上述したとおりである。
FIG. 8 is a detailed view of the maintenance cover 6 of this embodiment.
The long holes 6-1 and 6-2 are formed in the maintenance cover 6 so as to be substantially parallel to each other. Since the lengths of the long holes 6-1 and 6-2 determine the slide length, they are longer than at least the widths of the holes of the housing and the windows 6-3 of the maintenance cover 6.
The window 6-3 is as described above.
従来のメンテナンスカバー２は単にメンテナンス用コネクタ等を覆うことができる幅があればよかったが、本実施例ではメンテナンスカバー６を幅方向にスライドさせるため、さらにメンテナンスカバー６の開放時に、その一部が筐体の背面からせり出すようにするため、幅が広くなっている。そして、せり出す側の角には、円弧状の面取りが成されている。
更に、せり出す部分の裏側（筐体に接する側）には、メンテナンスカバー６を閉める際のスライド方向を示す閉め方向指示表記６−４が印刷あるいは刻印されている。
The conventional maintenance cover 2 has only to be wide enough to cover the connector for maintenance, but in this embodiment, the maintenance cover 6 is slid in the width direction. In order to protrude from the back of the housing, the width is increased. An arc-shaped chamfer is formed at the protruding corner.
Furthermore, a closing direction indication notation 6-4 indicating a sliding direction when the maintenance cover 6 is closed is printed or stamped on the back side of the protruding portion (the side in contact with the housing).
図９は、本実施例のメンテナンスカバー付き通信機器の天面図（メンテナンスカバー開放時）である。メンテナンスカバー６をスライドして開放したときに、メンテナンスカバー６が筐体５からはみ出すため、上方から装置を見ると、メンテナンスカバー６のはみ出しが目視できるほか、そのはみ出した部分に設けられた閉め方向指示表記が読み取れるようになっている。
これにより、メンテナンス時のメンテナンスカバースライド開放後、運用開始する時に、メンテナンスカバーを閉め忘れていることに容易に気が付くことができる。
FIG. 9 is a top view of the communication device with a maintenance cover according to the present embodiment (when the maintenance cover is opened). When the maintenance cover 6 is slid and opened, the maintenance cover 6 protrudes from the housing 5, so that when the device is viewed from above, the maintenance cover 6 can be visually observed, and the closing direction provided at the protruding portion The instruction notation can be read.
Thereby, after starting the maintenance cover slide at the time of maintenance, when starting operation, it can be easily noticed that the maintenance cover is forgotten to be closed.
本実施例によれば、筐体やメンテナンスカバーに溝などの複雑な勘合構造を用いずに、メンテナンスカバーを開閉可能にし繋止することができる。
なお本実施例で用いた固定ネジ７−１、７−２は、それらを締めることで、メンテナンスカバー６の自由なスライドを拘束する機能を有しているが、筐体５とメンテナンスカバー６の接合面にそれぞれ設けた凹部及び凸部による緩い嵌合等の別の拘束手段を設ければ、ネジ以外の固定手段を用いることができる。例えば、筐体の一部として形成し、メンテナンスカバー６を取り付けた後に先端をカシメて脱落しないようにした固定手段を用いても良い。
According to the present embodiment, the maintenance cover can be opened and closed without using a complicated fitting structure such as a groove in the housing or the maintenance cover.
Note that the fixing screws 7-1 and 7-2 used in the present embodiment have a function of restraining the free slide of the maintenance cover 6 by tightening them. If another restraining means such as a loose fitting by a concave portion and a convex portion respectively provided on the joint surface is provided, a fixing means other than a screw can be used. For example, a fixing means that is formed as a part of the housing and that does not fall off by crimping the tip after the maintenance cover 6 is attached may be used.
