Description

本発明は通信機器用端末ケース、特にノックアウト構造に関する。 The present invention relates to a terminal case for communication equipment, and more particularly to a knockout structure.

通信機器用端末は、通常、図６（ａ）〜（ｃ）のように、上方開口の箱状の本体ケースＡと、それに開閉可能な蓋ケースＢを備え、本体ケースＡ内に内部ユニットＣが収容され、内部ユニットＣの上から本体ケースＡに蓋ケースＢを被せてある。内部ユニットＣには通信システムに必要な機器が内蔵されており、電源プラグを接続するための電源端子Ｄ、同軸ケーブル接続用の接栓Ｅ（Ｆ型コネクタ）等の外部機器接続具が装備されている。 As shown in FIGS. 6A to 6C, a communication device terminal generally includes a box-shaped main body case A with an upper opening and a lid case B that can be opened and closed, and an internal unit C is provided in the main body case A. The main body case A is covered with the lid case B from above the internal unit C. The internal unit C contains the equipment necessary for the communication system and is equipped with a power terminal D for connecting a power plug, an external equipment connector such as a plug E (F type connector) for connecting a coaxial cable, and the like. ing.

本体ケースＡと蓋ケースＢには半円孔Ｆ、Ｇが開口されており、本体ケースＡ内に内部ユニットＣを入れ、その上から、蓋ケースＢを本体ケースＡに被せると、両ケースの半円孔Ｆ、Ｇ同士が対向して接栓Ｅを挟むことができ、電源端子Ｄの外側に円形の差込み口が形成されるようにしてある。 Semicircular holes F and G are opened in the main body case A and the lid case B. When the internal unit C is put in the main body case A and the lid case B is put on the main body case A from above, both cases are The semicircular holes F and G can face each other to sandwich the contact plug E, and a circular insertion port is formed outside the power supply terminal D.

通信機器用端末の場合は、それを通信システムに敷設するまでは、電源端子Ｄに電源コネクタが接続されないこともある。しかし、本体ケースＡと蓋ケースＢには電源プラグ差込み用の導入口が開口されているため、それら導入口に電源プラグが差し込まれないと、導入口から塵芥が侵入して電源端子Ｄに付着することがある。これが原因で、電源端子Ｄに電源プラグを接続すると接触不良が生じたり、内部ユニットに不具合が生じたりすることがある。 In the case of a communication device terminal, the power supply connector may not be connected to the power supply terminal D until it is installed in the communication system. However, since the main body case A and the lid case B have the inlets for inserting the power plugs, if the power plugs are not inserted into the inlets, dust will enter from the inlets and adhere to the power supply terminal D. There is something to do. Due to this, when a power plug is connected to the power terminal D, contact failure may occur or an internal unit may malfunction.

従来は、これら障害を防止するため、導入口の外側に閉塞板（ノック板）を設けて、不要時には導入口を閉塞しておき、使用時（電源プラグの接続時）にノック板を取り外して（除去して）導入口を開口し、その導入口から電源プラグを挿入して、内部ユニットＣの電源端子Ｄに接続できるようにしてある。このような構造を通称ノックアウト構造といっている。ノックアウト構造は金属ケースや樹脂ケースに採用されている。ノックアウト構造の従来例として特許文献１、２がある。 Conventionally, in order to prevent these obstacles, a blocking plate (knock plate) is provided outside the inlet, and the inlet is closed when not needed, and the knock plate is removed when using (when connecting the power plug). The inlet is (removed) opened, and the power plug is inserted from the inlet so that the power supply terminal D of the internal unit C can be connected. Such a structure is commonly called a knockout structure. The knockout structure is used for metal cases and resin cases. As a conventional example of the knockout structure, there are Patent Documents 1 and 2.

特開２００４−２２９４６４号公報JP, 2004-229464, A 特開２００７−１７４７７５号公報JP, 2007-174775, A

特許文献１、２のようなノックアウト構造にすると、配線などの必要時に、必要箇所のノック板を除去すればよいため、通信システムへの敷設状況に応じた配線が可能となり便利である。しかし、ノック板が本体ケース又は蓋ケースのいずれか一方にしか設けられていないため、電源端子或いはＦ型コネクタが本体ケースと蓋ケースの突合せ部（開口部周縁）に跨っているときは、特許文献１、２のノックアウト構造は採用することができない。また、ノック板を不要意に除去すると、除去されたノック板がノック板除去跡の開口から本体ケース又は蓋ケース内に落下してしまい通信機器に不具合が生じかねない。 When the knockout structure as in Patent Documents 1 and 2 is adopted, the knock plate at a required position may be removed when wiring or the like is needed, and therefore wiring is possible according to the laying condition in the communication system, which is convenient. However, since the knock plate is provided on only one of the main body case and the lid case, when the power supply terminal or the F-type connector straddles the abutting portion (periphery of the opening) of the main body case and the lid case, The knockout structure of Documents 1 and 2 cannot be adopted. Further, if the knock plate is unintentionally removed, the removed knock plate may fall into the main body case or the lid case from the opening of the knock plate removal mark, which may cause a malfunction in the communication device.

本発明の解決課題は、内部ユニットの電源端子等（外部機器接続具）の外側の導入口が本体ケースと蓋ケースの突合せ部に跨っていても、導入口を一枚のノック板で閉塞することでき、必要時にノック板を簡易に取り外す（ノックアウトする）ことができるノックアウト構造を提供すること、また、取り外したノック板がケース内に落下するのを阻止できるようにしたノックアウト構造を提供することにある。 The problem to be solved by the present invention is to close the inlet with a single knock plate even when the inlet outside the power supply terminal of the internal unit (external device connector) straddles the abutting portion of the main body case and the lid case. It is possible to provide a knockout structure that can be easily removed (knocked out) when necessary, and a knockout structure that can prevent the removed knock plate from falling into the case. It is in.

本発明の通信機器用端末ケースは、一面に開口部がある本体ケースと、一面に開口部がある蓋ケースを備え、両ケースは夫々の開口部周縁を突き合わせて閉じて、両ケース内に内部ユニットを収容できる通信機器用端末ケースであり、突き合わせると内部ユニットの外部機器接続具の外側に導入口が形成され、その導入口の外側にその導入口を閉塞するノック板を備えたものである。 The terminal case for a communication device of the present invention includes a main body case having an opening on one surface and a lid case having an opening on one surface. A terminal case for communication equipment that can accommodate a unit, which is formed with an introduction port outside the external device connection tool of the internal unit when butt-mounted, and with a knock plate that closes the introduction port outside the introduction port. is there.

ノック板は本体ケースと蓋ケースの双方に跨る導入口を一枚で閉塞できる形状とサイズであり、本体ケースと蓋ケースのいずれか一方に設けてある。ノック板の裏側にはノック板を取り外す治具を挿入可能な治具挿入空間を設けることができる。ノック板の裏面側に、本体ケースと蓋ケースのいずれか一方から取り外されたノック板がそれらケース内に落下するのを防止できる落下防止突起を備えることもできる。 The knock plate has a shape and size capable of closing the introduction port extending over both the main body case and the lid case with one sheet, and is provided on either the main body case or the lid case. A jig insertion space into which a jig for removing the knock plate can be inserted can be provided on the back side of the knock plate. On the back side of the knock plate, a fall prevention protrusion that can prevent the knock plate removed from either the main body case or the lid case from falling into the case can be provided.

本発明は次のような効果がある。
（１）本体ケースと蓋ケースの突合せ部に、両ケースに跨って形成される導入口が、ノック板で閉塞されているため、導入口から塵芥が侵入して内部ユニット不具合の一因になることがない。
（２）本体ケースと蓋ケースの双方に跨る導入口を一枚のノック板で閉塞できるため構造が簡潔である。
（３）一枚のノック板を取り外すだけで導入口が開くので、外部機器の接続が容易にできる。

（５）ノック板の裏面側に落下防止突起があるので、取り外されたノック板がケース内に落下することがなく、ノック板がケース内で悪さをすることがない。 The present invention has the following effects.
(1) In the abutting portion of the main body case and the lid case, the introduction port formed over both cases is closed by the knock plate, so dust is introduced from the introduction port and causes a malfunction of the internal unit. Never.
(2) The structure is simple because the knocking plate that covers both the main body case and the lid case can be closed.
(3) The introduction port can be opened by simply removing one knock plate, so that an external device can be easily connected.
(4) Since there is a jig insertion space on the back side of the knock plate, it is possible to easily remove the knock plate by inserting a jig such as a screwdriver there.
(5) Since the knock prevention protrusion is provided on the back surface side of the knock plate, the removed knock plate does not fall into the case, and the knock plate does not become bad in the case.
