Abstract

PURPOSE:To enable the discrimination of connection object of a specified cable easily by providing a display lighted or rumbled by the current flowed in one connector from an electrode provided in the other connector. CONSTITUTION:A pair of tester bars 6 connected to a power source 5 such as a battery are brought into contact with as electrodes 4 on one connector 1A. Current is thereby supplied to a lamp 3 on the other connector 1A through a lead inside of a cable 2A to light the lamp 3. Consequently, the relation between one connector 1A and the other connector 1A can be judged visually, and a terminal of a concentrator, to which a transceiver cable device having that connector 1A is connected, can be recognized. Connection object of a specified cable can be thereby judged easily without following the cable itself.

Next, the operation will be described. The workstation 10 is connected to a concentrator 11 via a transceiver cable device, and the concentrator 11 is connected to an Ethernet 12 via a transceiver cable device and an Ethernet transceiver 13 similar to the above. Therefore, communication between the workstations 10 can be performed by small-scale LAN communication, and the workstations 10 can be arbitrarily added.

[0005]

Since the conventional transceiver cable device for Ethernet is configured as described above, when the number of transceiver cable devices used is large, each transceiver cable device connected to the concentrator 11 is connected. It is not clear which workstation 10 the cable 2 of the device is connected to, and therefore the floor 14 can be used to identify each transceiver cable device.
Each of the cables 2 below must be traced one by one, which is very troublesome.

The invention of claim 1 has been made to solve the above problems, and it is possible to instantly determine the connection of a specific cable connected to a concentrator or the like without tracing the cable itself. The purpose is to obtain a transceiver cable device.

It is another object of the present invention to provide a transceiver cable device capable of discriminating a specific cable connected to a concentrator or the like by a simple switch operation.

[0008]

According to a first aspect of the present invention, there is provided a transceiver cable device in which one of the connectors is provided with an indicator which is lit or sounded by a current flowing from an electrode provided in the other connector. Is.

In the transceiver cable device according to a second aspect of the present invention, one of the connectors is provided with an indicator which is turned on or sounds by receiving a current from the power supply line in the cable by a switch operation provided on the other connector. It is provided.

[0010]

In the transceiver cable device according to the first aspect of the present invention, an electrode provided on one side of the connector is brought into contact with a tester rod of an external power source so that the electrode is provided on the other side of the connector via the electrode and the cable. The current is led to the indicator that is turned on and the indicator is turned on or sounded.

In the transceiver cable device according to the second aspect of the present invention, by operating a switch provided on one side of the connector, a current is led from the power supply line in the cable to an indicator provided on the other side of the connector, and this indicator is displayed. Turn on or ring.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1A is a pair of connectors, 2A is a cable connecting these respective connectors 1A, and these constitute a transceiver cable device for Ethernet. 4 is a pair of electrodes provided on each connector 1A, 3
Is a lamp provided as a display on each connector 1A, and the lamp 3 on one connector 1A is turned on by a current flowing from the electrode 4 provided on the other connector 1A.

Here, the above current is generated by connecting a pair of tester rods 6 connected to a power source 5 such as a battery to one connector 1A.
By contacting the electrode 4 above, the cable 2A
The other connector 1A via the inner lead (not shown)
It can be flowed to the upper lamp 3. Therefore, for example, the leads for two circuits are provided in the cable 2A so that both lamps 3 can be selectively turned on.

Next, the operation will be described. Now, which terminal of the concentrator 11 or which workstation 10 a specific one of the many transceiver cable devices connected between the workstation 10 and the concentrator 11 as shown in FIG. 5 is connected to? When it is desired to discriminate, the tester bar 6 connected to the power source 5 is brought into contact with the electrode 4 of the one specific connector 1A as shown in the figure.

Therefore, a current is supplied to the lamp 3 on the other connector 1A via the tester rod 6, the electrode 4 and the lead in the cable 2A on the one connector 1A,
This lamp 3 lights up. Therefore, the correspondence relationship between the one connector 1A and the other connector 1A can be visually determined, and the transceiver cable device having the connector 1A is connected to the concentrator 11 and the workstation 10 at which position. You will be able to recognize clearly.

Example 2. In the above embodiment, the lamp 3 is used as the indicator, but as shown in FIG. 2, the buzzer 7 is provided on each connector 1A instead of the lamp 3.
May be provided. In this case, the correspondence between one connector 1A and another connector 1A can be judged for each cable 2A by listening to the ringing sound of the buzzer 7, and it is possible for the visually impaired person to recognize the ringing sound. The different tones allow for more specific identification for each transceiver cable device.

Embodiment 3. 3 shows another embodiment of the present invention. This is because each connector 1A is provided with a switch 8 and a lamp 9 as a display, and the lamp 9 provided on one side of each connector 1A is operated by operating the switch 8 provided on the other connector 1A to It is designed such that the current from the power supply line is supplied to turn it on.

According to this embodiment, the need for an external power source is eliminated, and by operating the switch 8 on the connector 1A on one side, the lamp 9 on the connector 1A on the other side is turned on, so that they correspond to each other. The connectors 1A can be distinguished from each other in the same manner as in the above embodiment, and the operation and work thereof can be simplified as compared with the above embodiment. Even in this case, it is optional to use a buzzer instead of the lamp 9 as the display.

[0019]

As described above, according to the first aspect of the invention, one of the connectors is provided with the indicator which is lit or sounded by the current flowing from the electrode provided in the other connector. Therefore, there is an effect that a connection destination of a specific cable to a workstation, a concentrator, or the like can be easily and reliably discriminated visually or aurally without tracing the cable itself.

According to the second aspect of the present invention, one of the connectors is provided with an indicator which lights up or sounds by receiving a current from the power supply line in the cable by operating a switch provided on the other connector. Since it is configured as described above, there is an effect that a specific cable connected to a workstation, a concentrator or the like can be easily and surely determined by a simple switch operation.
