[Technical field]

[0001] The present invention relates to a connection adapter for an IP conversion device for connecting an IP conversion device to a level measuring device, and a level measuring method for an IP conversion device using this connection adapter for an IP conversion device. [Background technology]

[0002] Conventionally, there has been known a technology that enables voice conversations and fax communications using an IP network by converting voice and signals from a telephone or the like into IP (Internet Protocol) network signals via an IP conversion device (see, for example, Patent Document 1). When using this IP conversion device, it is necessary to measure the output level (output magnitude) of the IP conversion device at the time of installation and periodically, and the IP conversion device is connected to a level measuring device for measurement.

[0003] [Patent Document 1] JP 2012-44503 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, there were cases where the shape and type of the connector / terminal of the IP conversion device and the connector of the level measuring instrument were different. For example, while the female connector of the IP conversion device was an RJ-45 type, the female connector of the level measuring instrument was a special shape (for example, a shape with two long holes formed in parallel), and it was not possible to connect the IP conversion device and the level measuring instrument with a LAN cable with RJ-45 type male connectors on both ends. For this reason, for example, it was necessary to take apart the other end of the LAN cable, attach an alligator clip or the like to each line, and connect by clamping the female connector of the level measuring instrument with the alligator clip, which not only took time and effort, but also there was a risk that the alligator clip would come off or the alligator clips would come into contact with each other, causing a short circuit.

[0005] Therefore, an object of the present invention is to provide a connection adapter for an IP conversion device that enables easy connection of an IP conversion device with a level measuring instrument having different connector types, and a level measurement method for an IP conversion device using this connection adapter for an IP conversion device. [Means for solving the problem]

[0006] In order to solve the above problem, the invention of claim 1 provides an IP cable having one end connected to an adapter body and the other end provided with an IP male connector that can be attached to an IP side female connector of an IP conversion device, and a measurement male connector that can be attached to a measurement side female connector of a level measuring instrument having a different shape from the IP side female connector at one end and is provided to the adapter body at the other end. Four Body side female connector One of and a measurement cable provided with a main body male connector that can be attached to the adapter body, and the IP male connector of the IP cable is attached to the IP side female connector, and the measurement male connector of the measurement cable is attached to the measurement side female connector, and the main body male connector is attached to the main body side female connector, whereby the IP conversion device and the level measuring instrument are electrically connected via the adapter body. The four main body side female connectors have the same shape as the measurement side female connectors, and are terminals for voice signals of a voice being transmitted in a four-wire line, terminals for voice signals of a voice being received in a four-wire line, terminals for transmission signals, and terminals for reception signals. The present invention relates to a connection adapter for an IP conversion device.

[0008] Claim 2 The invention is as follows: 1 to A level measurement method for an IP conversion device using the connection adapter for the IP conversion device described above, comprising the steps of: attaching an IP male connector of the IP cable to the IP side female connector; attaching a measurement male connector of the measurement cable to the measurement side female connector; and The above four Body side female connector One of and the level of an output signal from the IP conversion device is measured by the level measuring device. Effect of the Invention

[0009] Claim 1 and claims 2According to the invention described in the above, the IP conversion device and the level measuring device can be electrically connected via the adapter body by simply attaching the IP male connector of the IP cable to the IP side female connector of the IP conversion device, attaching the measurement male connector of the measurement cable to the measurement side female connector of the level measuring device, and attaching the main body male connector to the main body side female connector of the adapter body. In other words, even without using an alligator clip or the like, it is possible to easily, properly, and safely connect the IP conversion device and the level measuring device, which have different connector types, by simply attaching each male connector to a corresponding female connector. As a result, it becomes possible to easily, properly, and safely measure the level of the output signal from the IP conversion device with the level measuring device.

[0012] Hereinafter, the present invention will be described based on the illustrated embodiment.

[0013] Fig. 1 is a perspective view showing an IP conversion device connection adapter 1 according to an embodiment of the present invention, Fig. 2 is a front view showing an adapter body 2 and an IP cable 3 of the IP conversion device connection adapter 1, and Fig. 3 is a front view (a) and a side view (b) showing the periphery of a measurement male connector 42 of a measurement cable 4 of the IP conversion device connection adapter 1. This IP conversion device connection adapter 1 is an adapter for connecting a level measuring instrument 201 to an IP conversion device 101 so as to enable measurement of an output signal level of the IP conversion device 101, and comprises an adapter body 2, an IP cable 3, and a measurement cable 4.

[0014] Here, the IP converter 101 and the level measuring instrument 201 are ready-made and existing devices and products, so detailed description thereof will be omitted, but are roughly as follows. That is, the IP converter 101 is a device for relaying a 4W / 4-wire or 2W / 2-wire analog voice line to an IP (Internet Protocol) network, and in this embodiment, it is a device that accommodates the 4W, SS (Signal Send, transmission signal), SR (Signal Receive, reception signal), etc. of the exchange and converts them into an interface for Ethernet signals such as 10Base-T or 100Base-TX on the IP network side. On the front or back of this IP converter 101, an RJ-45 type IP side female connector (RJ-45 type jack) 102 that serves as an output port for signals from the IP converter 101 is provided. Here, the RJ-45 type connector is an 8-pin type (8 connectors) connector that is generally used for LAN cables.

[0015] Level measuring instrument 201 is a handheld multi-function level measuring instrument equipped with functions necessary for testing and maintaining voice-band transmission paths, transmission devices, and communication devices, and in this embodiment, it mainly measures the output level of signals from IP conversion device 101. On the top surface of this level measuring instrument 201, various terminals including a measurement-side female connector (level meter input terminal) 202 are provided, as shown in FIG. 4. This measurement-side female connector 202 is a connector with a different shape and type from IP-side female connector 102, and has two elongated holes 202a formed in parallel. In addition, on the front surface of level measuring instrument 201, as shown in FIG. 1, a display 203 for displaying measurement results and the like, and a group of keys 204 for inputting various commands and the like are provided.

[0016] As shown in FIG. 2, the adapter body 2 is a substantially rectangular box-shaped body with four sets of body-side female connectors 21, 22, 23, 24 on the front side. The body-side female connectors 21, 22, 23, 24 are the same shape as the measurement-side female connector 202, with two long holes 2a formed in parallel. Here, the first body-side female connector 21 is a terminal for voice signals of transmission in a four-wire line (interface signal 4WS of an OD dedicated line), the second body-side female connector 22 is a terminal for voice signals of reception in a four-wire line (4WR), the third body-side female connector 23 is a terminal for transmission signals (SS), and the fourth body-side female connector 24 is a terminal for reception signals (SR). In this embodiment, an existing terminal box in which the body-side female connectors 21, 22, 23, 24 are provided is used or appropriated as the adapter body 2.

[0017] One end of the IP cable 3 is connected to the adapter body 2 from the top surface of the adapter body 2. The IP cable 3 is composed of a LAN cable, and the other end is provided with an IP male connector 31 that can be attached to the IP side female connector 102 of the IP conversion device 101. That is, the IP male connector 31 is an RJ-45 plug that is shaped to fit the IP side female connector 102, that is, an RJ-45 jack (it is properly attached and connected simply by inserting it).

[0018] On the other hand, one end of the IP cable 3 is connected to predetermined body-side female connectors 21, 22, 23, 24. That is, in this embodiment, in order to measure the output signal level of the IP conversion device 101, the "send +" and "send -" pin wires on one end of the IP cable 3 are connected to the long hole 2a of the first body-side female connector 21, respectively.

[0019] As shown in FIG. 1, the measurement cable 4 has a measurement male connector 42 at one end of a cable body 41 that can be attached to the measurement side female connector 202 of the level measuring device 201, and a body male connector 43 at the other end that can be attached to the body side female connectors 21, 22, 23, 24 of the adapter body 2. As described above, the measurement side female connector 202 and the body side female connectors 21, 22, 23, 24 have the same shape, so the measurement male connector 42 and the body side male connector 43 have the same shape. Specifically, the measurement male connector 42 is described as follows: as shown in FIG. 3, one end side of the cable body 41 is covered with a cylindrical connector cover 40, and two flat connector plates 42a are formed to protrude in parallel from the upper surface of this connector cover 40. The two connector plates 42a are formed to fit the measurement side female connector 202 and the body side female connectors 21, 22, 23, 24 (so that they are properly attached and connected by simply inserting them).

[0020] As shown in FIG. 1, by attaching the IP male connector 31 of the IP cable 3 to the IP side female connector 102, attaching the measurement male connector 42 of the measurement cable 4 to the measurement side female connector 202, and attaching the main body male connector 43 to the first main 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 main body 2 and the measurement cable 4, and the output signal from the IP conversion device 101 is transmitted and input to the level measuring device 201.

[0021] Next, a level measuring method for the IP converter 101, which measures the output level of the IP converter 101 using the IP converter connection adapter 1 having the above configuration, will be described.

[0022] 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 main body male connector 43 is attached to the first main body side female connector 21. Then, an audio 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.

[0023] As described above, according to the level measurement method of the IP conversion device connection adapter 1 and 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, the measurement male connector 42 of the measurement cable 4 is attached to the measurement side female connector 202 of the level measurement device 201, and the main body male connector 43 is attached to the first main body side female connector 21 of the adapter main body 2, and the IP conversion device 101 and the level measurement device 201 can be electrically connected via the adapter main body 2. That is, even without using an alligator clip or the like, the IP conversion device 101 and the level measurement device 201, which have different connector types, can be easily, properly, and safely connected by simply inserting and attaching each male connector 31, 42, 43 to the corresponding female connectors 102, 202, 21. As a result, the level of the output signal from the IP conversion device 101 can be easily, properly, and safely measured by the level measurement device 201.

[0024] In addition, because the main body side female connectors 21, 22, 23, 24 have the same shape as the measurement side female connector 202, the male connectors 42, 43 at both ends of the measurement cable 4 can be made to have the same shape, making it possible to simplify the configuration of the measurement cable 4. Moreover, since the measurement cable 4 provided with the male connectors 42, 43 at both ends that fit the measurement side female connectors 202 is a cable that is generally provided and used when using the level measuring instrument 201, it becomes possible to use an existing, ready-made cable as the measurement cable 4. For example, the cable that is provided with the level measuring instrument 201 can be used as the measurement cable 4 in the present invention.

[0025] Although the embodiment of the present invention has been described above in detail, the specific configuration is not limited to this embodiment, and the present invention includes design changes and the like within the scope of the gist of the present invention. For example, in the above embodiment, the IP cable 3 is integrally provided with the adapter body 2, but the IP cable 3 may be detachable from the adapter body 2. Also, although the case where the measurement cable 4 is connected only to the first body-side female connector 21 of the adapter body 2 has been described, the measurement cable 4 may be connected to the other body-side female connectors 22, 23, 24 to which the pin wire of the IP cable 3 is connected according to the output signal to be measured.
