  When connecting the jumper lines, for example, in the case of a telephone line, it is necessary to connect six jumper lines per line, and each line configuration is configured with a dedicated tool. Furthermore, when the jumper line is connected, the line level is measured and the line level is adjusted. Then, if necessary, the attenuator (attenuator) is adjusted by removing the board of the terminal device. When a working line is mounted on the same board, the line is stopped.

  Further, when the configured line is no longer necessary, the jumper wires configured on the main wiring board and the intermediate wiring board are removed. Even if the removed jumper line is used for another connection, the length of each communication line is excessive and insufficient, and in most cases, it is discarded.

  There is an apparatus that eliminates such a jumper line connection (see, for example, Patent Document 1). In this apparatus, a connection using a plug is performed instead of a jumper wire to be wire-wrapped.

By such lines 10 ₂₁ to 10 ₂₆ , for example, signals flowing through the attenuator 11 and the U link 13, signals flowing through the attenuator 12 and the U link 14, and signals flowing through the test plugs 15 and 16 are made visible.

  Next, the operation of the communication line connecting apparatus according to this embodiment will be described. When this communication line connection device is installed in an intermediate wiring board for voice communication, it is a wrapping terminal provided in front of the intermediate wiring board, and a wrapping terminal for connecting the communication lines to be connected, An operator inserts the socket terminals 42A to 42F of the communication line 41 of the communication line connection device and the socket terminals 52A to 52F of the communication line 51. Thereby, the operator can connect the communication line connection device to the intermediate wiring board. That is, the communication line connection device functions as a jumper line.

  Thereafter, the operator adjusts the length A of the communication line 41 with the adjuster 20 and adjusts the length B of the communication line 51 with the adjuster 30. That is, the communication line connection device has a function of adjusting the length of the jumper line.

When measuring the line level of the signal flowing from the communication lines 41A and 41B to the communication lines 51A and 51B, the measuring instrument terminal for measuring the level is connected to the openings 13B ₄₁ and 13C ₄₁ of the U link 13. Plug in. Thus, the measuring instrument is connected between the communication line 41A, and 41B the communication line 51A, the connecting line _{10 1A} and the connecting line _{10 1B} which connects a 51B. Thereafter, the operator measures the line level with the connected measuring instrument. When adjusting the level, the operator turns on / off the switches 11E to 11H of the attenuator 11 to set the line level to a predetermined value.

  Similarly, the measurement and adjustment of the line level of the signal flowing from the communication lines 51C and 51D to the communication lines 41C and 41D can be performed using the U link 14 and the attenuator 12.

  There are also times when the state of connection by the communication line connection device is checked. At this time, when the operator pulls out the U links 13 and 14 and the test plugs 15 and 16 from the apparatus main body 10, the line can be made non-conductive. Thereby, since the predetermined signal is intermittent, it is possible to check whether the signal is normally delivered, that is, whether the communication line 41 and the communication line 51 are normally connected.

  Further, when removing the communication line connection device, from the lapping terminal of the intermediate wiring board, the socket terminals 42A to 42F of the communication line 41 of the communication line connection device, and the socket terminals 52A to 52F of the communication line 51, Is removed by the operator. Thereby, the connection by the communication line connection device can be released in the same manner as the removal of the jumper line. In addition, adjusters 20 and 30 are provided in the communication line connection apparatus. Thereby, since the length A of the communication line 41 and the length B of the communication line 51 can be changed, the communication line connection device can be reused when another communication line is connected.

  Thus, according to this embodiment, it is not necessary to use a conventional connector. Further, since the U links 13 and 14 are detachable, it is possible to check whether the connection of the connection line for transmitting a signal such as an audio signal is normal. Furthermore, according to this embodiment, since the test plugs 15 and 16 are detachable, it is possible to check whether the connection of the connection line for transmitting a signal such as a calling signal is normal.

Further, according to this embodiment, the following effects can be achieved.
a. Tools such as a sheath stripper and an electric wrapper for the communication line 41 and the communication line 51 can be eliminated.
b. Since the socket terminals 42A to 42F of the communication line 41 and the socket terminals 52A to 52F of the communication line 51 are used, work skills such as wire wrapping work are unnecessary, and anyone can easily construct a line.
c. The working time for the intermediate wiring board can be greatly reduced.
Before improvement: Stripping 12 times, connecting 12 times (3 to 10 minutes)
After improvement: 12 pin connections (within 1 minute)
d. The lengths of the communication lines 41 and 51 can be adjusted by the adjusters 20 and 30 (cable length adjusters).
e. The line level can be adjusted by attenuators 11 and 12 (variable attenuators) mounted on the communication line connection device.
f. It is not necessary to stop the adjacent line mounted on the same board at the terminal station.
g. Line level measurement and signal test are possible with the U links 13 and 14 mounted on the communication line connection device.
h. Since the attenuators 11 and 12 and the U links 13 and 14 are mounted, the level can be adjusted while the line is configured.
i. Since the color coding is performed based on the signals for the insertion ports 10 _11A , 10 _{11B of the} connection paths 10 _1A to 10 _1F and the surface 10 ₂₀ of the apparatus main body 10, measurement errors and connection errors are unlikely to occur.
j. When the line is removed, the communication line connection device can be removed from the wiring board and reused.
k. Since it is pin connection by socket terminal 42A-42F and socket terminal 52A-52F, it is not mistaken for the cable in operation.

(Embodiment 2)
A communication line connection apparatus according to this embodiment is shown in FIG. In this embodiment, components that are considered to be the same as or the same as those in the communication line connecting apparatus according to the first embodiment described above are denoted by the same reference numerals, and description thereof is omitted. In the communication line connection apparatus of FIG. 12, the adjusters 20 and 30 according to the first embodiment are externally attached to the apparatus main body 10. In FIG. 12, the adjuster 30 is not shown for the sake of illustration.

  The adjuster 20 according to the second embodiment stores a winder (not shown) for winding the communication line 41 inside a cylindrical storage body 21. As the winder, there are various types such as a device that manually winds up the communication line 41 and a device that winds up the communication line 41 using an elastic force such as a spring.

  According to the second embodiment, since the adjusters 20 and 30 are externally attached, the apparatus main body 10 can be reduced in size, and the selection range of the placement location of the adjuster 20 can be expanded.
