Description
本発明は、ＩＰ変換装置をレベル測定器に接続するためのＩＰ変換装置用接続アダプタおよび、このＩＰ変換装置用接続アダプタを使用したＩＰ変換装置のレベル測定方法に関する。 The present invention relates to an IP conversion device connection adapter for connecting an IP conversion device to a level measuring instrument, and a level measurement method for an IP conversion device using this IP conversion device connection adapter.
従来から、ＩＰ変換装置を介して電話機等からの音声や信号をＩＰ（インターネットプロトコル）網の信号に変換することで、ＩＰ網を利用した音声会話やＦＡＸ通信などを可能にする技術が知られている（例えば、特許文献１参照。）。このＩＰ変換装置を利用する場合、設置時や定期的にＩＰ変換装置の出力レベル（出力の大きさ）を測定する必要があり、ＩＰ変換装置をレベル測定器に接続して測定していた。 Conventionally, there has been known a technology that enables voice conversations and FAX communications using an IP network by converting voices and signals from a telephone or the like into IP (Internet Protocol) network signals via an IP conversion device. (See Patent Document 1, for example). When using this IP conversion device, it is necessary to measure the output level (magnitude of output) of the IP conversion device at the time of installation or periodically, and the IP conversion device is connected to a level measuring device.
しかしながら、ＩＰ変換装置のコネクタ・端子とレベル測定器のコネクタとの形状・種類が異なる場合があった。例えば、ＩＰ変換装置の雌コネクタがＲＪ－４５型であるのに対して、レベル測定器の雌コネクタが特殊な形状（例えば、２つの長穴が平行に形成された形状）の場合があり、両端にＲＪ－４５型の雄コネクタが設けられたＬＡＮケーブルでは、ＩＰ変換装置とレベル測定器とを接続することができなかった。このため、例えば、ＬＡＮケーブルの他端側をばらして各線にミノムシクリップなどを取り付け、ミノムシクリップなどでレベル測定器の雌コネクタを挟んで接続しなければならず、手間と時間を要するばかりでなく、ミノムシクリップが外れたりミノムシクリップ同士が接触して短絡したりするおそれがあった。 However, there have been cases where the connector/terminal of the IP conversion device and the connector of the level measuring device are different in shape and type. For example, while the female connector of the IP conversion device is RJ-45 type, the female connector of the level measuring device may have a special shape (for example, a shape in which two oblong holes are formed in parallel). A LAN cable provided with RJ-45 type male connectors at both ends could not connect an IP conversion device and a level measuring device. For this reason, for example, it is necessary to separate the other end of the LAN cable, attach a bagworm clip or the like to each wire, and clamp the female connector of the level measuring instrument with the bagworm clip or the like to connect, which not only requires labor and time, but also requires time and effort. , there is a risk that the bagworm clip will come off or that the bagworm clips will come into contact with each other and short-circuit.
そこで本発明は、コネクタタイプが異なるＩＰ変換装置とレベル測定器を容易に接続することを可能にするＩＰ変換装置用接続アダプタおよび、このＩＰ変換装置用接続アダプタを使用したＩＰ変換装置のレベル測定方法を提供することを目的とする。 Accordingly, the present invention provides a connection adapter for an IP conversion device that enables easy connection of an IP conversion device with a different connector type to a level measuring instrument, and level measurement of the IP conversion device using this connection adapter for the IP conversion device.

The IP conversion device and the level measuring device are electrically connected via the adapter main body by attaching the main body male connector to the main body side female connector by attaching the connector to the main body male connector. It is a connection adapter for an IP conversion device.
請求項２の発明は、請求項１に記載のＩＰ変換装置用接続アダプタにおいて、前記本体側雌コネクタは、前記測定側雌コネクタと同形状となっている、ことを特徴とする。 According to a second aspect of the invention, there is provided the connection adapter for the IP conversion device according to the first aspect, wherein the body-side female connector has the same shape as the measurement-side female connector.
請求項３の発明は、請求項１または２のいずれか１項に記載のＩＰ変換装置用接続アダプタを使用したＩＰ変換装置のレベル測定方法であって、前記ＩＰ用ケーブルのＩＰ用雄コネクタを前記ＩＰ側雌コネクタに装着し、前記測定用ケーブルの測定用雄コネクタを前記測定側雌コネクタに装着して前記本体用雄コネクタを本体側雌コネクタに装着し、前記ＩＰ変換装置からの出力信号のレベルを前記レベル測定器で測定する、ことを特徴とする。 The invention of claim 3 is a level measurement method for an IP conversion device using the IP conversion device connection adapter according to claim 1 or 2, wherein the IP male connector of the IP cable is attached to the IP side female connector, attaching the measurement male connector of the measurement cable to the measurement side female connector, attaching the main body male connector to the main body side female connector, and outputting a signal from the IP conversion device is measured by the level measuring device.

測定用ケーブル４は、図１に示すように、ケーブル本体４１の一端に、レベル測定器２０１の測定側雌コネクタ２０２に装着可能な測定用雄コネクタ４２が設けられ、他端にアダプタ本体２の本体側雌コネクタ２１、２２、２３、２４に装着可能な本体用雄コネクタ４３が設けられている。また、上記のように、測定側雌コネクタ２０２と本体側雌コネクタ２１、２２、２３、２４とが同形状のため、測定用雄コネクタ４２と本体用雄コネクタ４３は同形状となっている。具体的には、測定用雄コネクタ４２について説明すると、図３に示すように、ケーブル本体４１の一端部側が筒状のコネクタカバー４０で覆われ、このコネクタカバー４０の上面から平板上の２つのコネクタ板４２ａが平行に突出して形成されている。この２つのコネクタ板４２ａは、測定側雌コネクタ２０２と本体側雌コネクタ２１、２２、２３、２４に適合するように（挿入するだけで適正に装着・接続されるように）形成されている。 As shown in FIG. 1, the measuring cable 4 is provided with a measuring male connector 42 that can be attached to the measuring side female connector 202 of the level measuring instrument 201 at one end of the cable body 41, and the adapter body 2 at the other end. A body male connector 43 that can be attached to the body side female connectors 21, 22, 23, and 24 is provided. As described above, since the measuring side female connector 202 and the body side female connectors 21, 22, 23, and 24 have the same shape, the measuring male connector 42 and the body male connector 43 have the same shape. Specifically, the male connector for measurement 42 will be described. As shown in FIG. A connector plate 42a is formed to protrude in parallel. These two connector plates 42a are formed so as to fit the measurement-side female connector 202 and the body-side female connectors 21, 22, 23, 24 (so that they can be properly attached and connected by simply inserting them).
そして、図１に示すように、ＩＰ用ケーブル３のＩＰ用雄コネクタ３１をＩＰ側雌コネクタ１０２に装着し、測定用ケーブル４の測定用雄コネクタ４２を測定側雌コネクタ２０２に装着して本体用雄コネクタ４３を第１の本体側雌コネクタ２１に装着することで、ＩＰ用ケーブル３、アダプタ本体２および測定用ケーブル４を介して、ＩＰ変換装置１０１とレベル測定器２０１とが電気的に接続され、ＩＰ変換装置１０１からの出力信号がレベル測定器２０１に伝達・入力されるようになっている。 Then, as shown in FIG. 1, the IP male connector 31 of the IP cable 3 is attached to the IP side female connector 102, the measurement male connector 42 of the measurement cable 4 is attached to the measurement side female connector 202, and the main body is connected. By attaching the male connector 43 to the first body-side female connector 21, the IP conversion device 101 and the level measuring device 201 are electrically connected via the IP cable 3, the adapter body 2, and the measurement cable 4. An output signal from the IP conversion device 101 is transmitted/input to the level measuring device 201 .
次に、このような構成のＩＰ変換装置用接続アダプタ１を使用してＩＰ変換装置１０１の出力レベルを測定する、ＩＰ変換装置１０１のレベル測定方法について説明する。 Next, a method for measuring the level of the IP conversion device 101, which measures the output level of the IP conversion device 101 using the IP conversion device connection adapter 1 having such a configuration, will be described.
まず、上記のように、ＩＰ用ケーブル３のＩＰ用雄コネクタ３１をＩＰ側雌コネクタ１０２に装着し、測定用ケーブル４の測定用雄コネクタ４２を測定側雌コネクタ２０２に装着して本体用雄コネクタ４３を第１の本体側雌コネクタ２１に装着する。そして、ＩＰ変換装置１０１から音声信号などを出力して、その出力信号のレベルをレベル測定器２０１で測定する。 First, as described above, the IP male connector 31 of the IP cable 3 is attached to the IP side female connector 102, the measurement male connector 42 of the measurement cable 4 is attached to the measurement side female connector 202, and the body male connector is attached. The connector 43 is attached to the first body-side female connector 21 . A voice signal or the like is output from the IP conversion device 101 and the level of the output signal is measured by the level measuring device 201 .
以上のように、このＩＰ変換装置用接続アダプタ１およびＩＰ変換装置１０１のレベル測定方法によれば、ＩＰ用ケーブル３のＩＰ用雄コネクタ３１をＩＰ変換装置１０１のＩＰ側雌コネクタ１０２に装着し、測定用ケーブル４の測定用雄コネクタ４２をレベル測定器２０１の測定側雌コネクタ２０２に装着して本体用雄コネクタ４３をアダプタ本体２の第１の本体側雌コネクタ２１に装着するだけで、アダプタ本体２を介してＩＰ変換装置１０１とレベル測定器２０１とを電気的に接続することができる。すなわち、ミノムシクリップなどを使用しなくても、各雄コネクタ３１、４２、４３をそれぞれに合った雌コネクタ１０２、２０２、２１に挿入、装着するだけで、コネクタタイプが異なるＩＰ変換装置１０１とレベル測定器２０１を容易かつ適正、安全に接続することが可能となる。この結果、ＩＰ変換装置１０１からの出力信号のレベルを容易かつ適正、安全にレベル測定器２０１で測定することが可能となる。 As described above, according to the IP conversion device connection adapter 1 and the level measurement method for the IP conversion device 101, the IP male connector 31 of the IP cable 3 is attached to the IP side female connector 102 of the IP conversion device 101. Simply by attaching the measuring male connector 42 of the measuring cable 4 to the measuring side female connector 202 of the level measuring device 201 and attaching the body male connector 43 to the first body side female connector 21 of the adapter body 2, IP conversion device 101 and level measuring device 201 can be electrically connected via adapter body 2 . That is, without using bagworm clips or the like, just by inserting and mounting the respective male connectors 31, 42, 43 into the corresponding female connectors 102, 202, 21, the IP conversion device 101 and the level of the connector types are different. It becomes possible to connect the measuring device 201 easily, properly and safely. As a result, the level of the output signal from the IP conversion device 101 can be measured easily, properly and safely by the level measuring device 201 .
また、本体側雌コネクタ２１、２２、２３、２４が測定側雌コネクタ２０２と同形状となっているため、測定用ケーブル４の両端の雄コネクタ４２、４３を同形状にすることができ、測定用ケーブル４の構成を簡素化することが可能となる。しかも、測定側雌コネクタ２０２に適合する雄コネクタ４２、４３が両端に設けられた測定用ケーブル４は、レベル測定器２０１を使用する際に一般に提供、使用されるケーブルであるため、既存・既製のケーブルを測定用ケーブル４として使用することが可能となる。例えば、レベル測定器２０１に付属されているケーブルを、本発明における測定用ケーブル４として使用することができる。 In addition, since the body-side female connectors 21, 22, 23, and 24 have the same shape as the measurement-side female connector 202, the male connectors 42 and 43 at both ends of the measurement cable 4 can be made the same shape, which enables the measurement. It is possible to simplify the configuration of the cable 4 for the transmission. Moreover, since the measuring cable 4 provided with the male connectors 42 and 43 that fit the measuring side female connector 202 at both ends is a cable that is generally provided and used when using the level measuring instrument 201, existing/off-the-shelf cables can be used. can be used as the cable 4 for measurement. For example, a cable attached to the level measuring instrument 201 can be used as the measuring cable 4 in the present invention.

Included in the invention. For example, in the above embodiment, the IP cable 3 is provided integrally with the adapter main body 2 , but the IP cable 3 may be detachable from the adapter main body 2 . Also, the case where the measurement cable 4 is connected only to the first main body side female connector 21 of the adapter main body 2 has been described, but according to the output signal to be measured, other pins and wires of the IP cable 3 are connected.
