Description

[Detailed description of the device]

[0001]

[Industrial application] This device is designed for use in telephone cable cores.
It concerns a control display panel .

[0002]

2. Description of the Related Art Conventionally, when performing a work such as checking the core wire of a telephone line cable (5), it is necessary to confirm whether or not the telephone line is being communicated by checking the wire end partial bullet of the telephone wiring cable (5). It has been carried out by the confirmation method such as that by the mobile handset such as聴話in the vessel (2).

[0003]

[Problems to be Solved by the Invention] However, it has been a conventional practice to confirm whether or not the line is in communication by listening to a portable handset or the like.
Method of telephone wiring due to uncertainty (5)
Of when executing the various work of core control such telephone distribution cable (5) from line end portion bullet unit (2), interferes with communication
It was inconvenient . Specifically, (a) It was time-consuming to check whether or not communication was in progress, since each line was carried by a mobile phone handset or the like. (B) If the telephone line in the non-communication state changes to the communication state immediately after the confirmation at the time of confirmation, or if the telephone line changes to the communication state during various operations, the communication may be disturbed. (C) It is difficult to determine that it is in a communication state when there is no sound at the time of listening even if it is in a communication state. If this happens, it will interfere with communication .

As an example of a conventional telephone terminal tester,
Is disclosed in Jitsukaihei 1-113455,
The tester uses a test code for each line on the central office side.
After connecting with clips, perform work such as core wire comparison
Format. Currently, it is installed in an exchange with tens of thousands of lines.
There are a number of local end line ammunition
Therefore, when performing a large number of test operations such as core control,
Look for the wire-end partial ammo of the
No, then reconnect to another line and inspect
Must be repeated. For this reason,
Work is not very laborious and extremely inefficient.
It was Therefore, there is a demand to eliminate these problems.
Was there.

[0005]

The present invention has been made in view of the above problems, and a lead wire cable (3) for connecting a large number of lines to the wire end partial ammunition (2) of a telephone wiring cable (5). line end portion provided a connector (4), said connector
For each telephone line each 1 line, which is connected via the (4), in order to confirm the presence or absence of receiving state and during communication of the line, 2
A line indicator light (7) using a color light emitting diode (8) ,
Connection jack board (1 with a pair of jacks (12)
1) is arranged and provided .

[0006]

[Action] to the cable core contrast for the display panel (1), display the status confirmation of non-communication and communication in the Aki line of the telephone line
Line indicator light (7) and a pair of jacks (1
Connection jack board (11) equipped with 2) for each line
One is provided for each of them, and many of them are arranged in a plane.
Therefore, when the line indicator (7) emits green light, it indicates that the telephone line is accommodated and the line is not in communication. When the line indicator (7) is in a red light emitting state, it indicates that the telephone line is accommodated and the line is in communication. When the line indicator (7) is not lit , it indicates that the telephone line is not accommodated, that is , the line is empty.

Therefore, the display panel (1) for checking the cable core wire
The core wire contrast work between the telephone wiring cable (5) and the outside, or the work of switching the core wire of the telephone wiring cable (5) ,
If the time line display lamp (7) of the green light-emitting state or non-light emission state, carried out without giving disturbance to the line during communication
can do. Also, attach the 2-core cord of the tester to both ends.
1-line plug equipped with a display panel for cable core wire comparison
(1) If it is inserted and connected to the target connection jack board (11) above, it will temporarily replace the jumper wire (6) connected to the line end partial ammunition (2) of the telephone wiring cable (5). It is possible to switch the accommodation of telephone lines. And many
For the core wire contrast work of the line,
(1) Easy in a short time by simply replacing the plug above
Can be done.

EXAMPLES Examples of the present invention will be described below. Figure 1
As shown in Figure 1 , the cable core wire control display panel (1) has an example
The line end part of the telephone distribution cable line end portion bullets device for 100 lines of (5) (2) and connected to 100 pairs of leads cable (3) as is connected through a connector (4)
ing. Stowed such as a telephone line for each line of the telephone lines, to confirm the presence or absence in the communication, two-color light-emitting diodes (8) as shown in FIG. 2, the diode (9), with built-in resistance of 10 k.OMEGA (10) Provided is a connection jack board (11) having 100 line indicator lights (7) and a pair of jacks (12) capable of observing the core wire of a telephone wiring cable (5).
It 100 sets of the line indicator lamp (7) and the connection jack panel (11) are arranged on the cable core wire display panel (1).
They are arranged in rows. As the arrangement order , numbers 1 to 100 are sequentially set for the arrangement of 4 columns in the vertical direction and 25 columns in the horizontal direction.

The cable core wire contrast display panel (1) has the above-mentioned structure , and the work such as the core wire contrast of the telephone wiring cable (5) is performed by checking whether the line indicator lamp (7) of the relevant line emits green light. , (If the operation is performed for a line that is not emitting light, communication will not be interrupted. Wait until the line indicator (7) of that line is emitting red light until it is emitting green light. If there is a need to temporarily switch the cable core of the telephone wiring cable (5), the cable core control tester 2
1-line plug with core cord at both ends
Target connection jack board (11) on the control display board (1 )
Switching can be easily performed by inserting and connecting to. Therefore, the core contrast work of a large number of lines is
Insert the plug on the cable core wire display panel (1)
It can be easily performed in a short time only by changing.

[0010]

[Effects of the Invention] The present invention has the configuration and operation described above.
What to do with the core wire contrast work of multiple lines of telephone wiring cable
Replace the plug on the display panel for the cable core wire contrast
It can be done easily in a short time, and it will surely prevent the communication line from being disturbed.
Have the benefit of being able to.
