2. Description of the Related Art Conventionally, an information wiring system using a twisted pair cable or a coaxial cable has been widely used in offices and factories for transmitting various information. The form of information transmitted by this type of system is not limited to analog signals of telephone lines, facsimile lines, etc., and often includes digital signals of LAN terminals. Also, regarding the content of information, all media such as audio signals, data signals, and image signals are included. In an integrated information wiring system in which such various information devices are configured as a network based on a unified architecture, in general, in case the information wiring needs to be changed due to changes in the office layout, etc. It is equipped with a wiring switching board. This wiring switching board is composed of a patch panel having a plurality of connecting portions, and a patch cord having connectors that can be connected to arbitrary connecting portions of the patch panel at both ends of the cable. When changing the information wiring, patch cords are connected and changed on the wiring switching board, but as the number of wirings or media connected to the wiring switching board increases, wiring mistakes occur on the wiring switching board. This makes it easier to manage the wiring change accurately. The connection destination on the patch cord may become unclear during such wiring changes.In that case, when confirming the connection destination, remove the patch cord from the patch panel and offline the transmission between information devices. However, there is a problem that communication is temporarily disabled.

Has a connector 2 at both ends of a cable 3, and the connector 2 is provided with a test port 6 that comes into contact with a power supply terminal 21 of a test power supply 20. The current supplied to the test port 6 of the connector 2 of the connection source is supplied to the light emitting diode 7 of the connector 2 to cause the light emitting diode 7 of the connection source to emit light, and the signal included in the cable 3 of the patch cord 4 is supplied. Power is also supplied to the light emitting diode 7 of the connector 2 of the connection destination via the line 8.
The connected light emitting diode 7 is also made to emit light at the same time. Thereby, the correspondence relationship between the connection source and the connection destination connector 2 can be visually confirmed. It is preferable that the port 6 and the light emitting diode 7 are exposed outside the connector 2 at an easily visible position so that the connection destination can be confirmed while the connector 2 is still connected.

FIG. 2 shows the internal structure of the connector 2 and the test power supply 20 used in this embodiment. Power supply for test 2
Reference numeral 0 has a built-in power supply circuit 22 from which a drive current for the light emitting diode 7 is supplied to the power supply terminal 21 exposed to the outside. The power supply terminal 21 is the connector 2

Is connected to the LED drive circuit 10 of the connector 2 of the connection destination, whereby the light emitting diodes 7 provided in the connectors 2 of both the connection source and the connection destination emit light at the same time. Although the signal line 8 for emitting light from the LED and the signal line 9 for transmitting information are separated in this embodiment, these may be used in common. That is, of the plurality of signal lines included in the cable 3, an unused line may be used as a signal line for LED light emission, or the original signal line for information transmission may be used as a signal line for LED light emission.
