The male contact insulator 4 has, for example, a rectangular coupling surface with the female connector 9, and a plurality of male contacts for connection are arranged parallel to the long sides of this rectangle, and the two connections at both ends of the male contact insulator 4 have a rectangular shape. Male contact 3a.

3b is used for the connection circuit of the light emitting diode 6.

The light emitting diode 6 is provided on the connection surface of the connector cable 2 of the male connector cover 5, and one terminal of the light emitting diode 6 is connected to the end of the male connection contact 1-3a by crimping or the like via the power supply side connection cotton 7a. , and the other terminal of the light emitting diode 6 is connected to the end of the male connection contact 1-3b via a ground side connection line 7b.

2, and is provided on a printed circuit board 13 in which the circuit is incorporated.

Each circuit on the printed circuit board 13 and a plurality of female connecting contacts are connected to the ends of the female connecting contacts via connecting wires, and are embedded in the female contact insulator 11 for support and insulation.

The coupling surface of the female contact insulator 11 with the male connector 1 has the same shape and approximately the same size as the male contact insulator 4, and the plurality of connecting female contacts supported by this female contact insulator 11 are connected to the male connector 1. The same number of male contacts as the contacts are embedded in the female contact insulator 11 at a position opposite to the supported male contact insulator 4. Among these plurality of connection female contacts, two connection female contacts ga and f3b at both ends are used for the connection circuit of the light emitting diode 6. The female contact Oa for connection is the power supply side contact rI
It is connected to the power supply voltage (vo) on the printed circuit board 13 via the ljt line 8a, and the female connection contact 10b is connected to the ground via the ground side connection line 8b.

When the male connector L and the female connector 9 are connected, the male contact is inserted inside the female contact, and the male contact insulator 4 and the female contact insulator 1 are connected.

Further, when the connector is not properly connected due to being loose, misaligned, etc., a closed circuit of the light emitting diode 6 is not formed, so the light emitting diode 6 does not light up. The user can know from the lighting of the light emitting diode 6 whether or not the connector is properly connected.

Note that this male connector 1 and female connector 9 have key and key models, so if the user connects the male connector 1 and female connector 9 incorrectly, the male connector 1 may be connected to the ground side connecting wire 7b of the light emitting diode connection circuit. There is no need to worry about damaging the light emitting diodes 6 by connecting the connectors 9 and the power supply side connection wires 8a of the light emitting diode connection circuit alternately.
