A contact 3 of the relay 2, a lamp (for example, a lamp such as a positioning lamp, hereinafter abbreviated as a lamp) 4 and a fuse 5 are connected in series. At the same time, the light switch 6 and the coil 7 of the relay 2 are connected in series between one end (+ side) of the battery 1 and ground (vehicle body ground).

  In such a circuit configuration, when the light switch 6 is turned on, a direct current is supplied from the battery 1 to the coil 7 of the relay 2, and the contact 3 of the relay 2 is turned on (conductive), and the contact of the battery 1 to the relay 2. A direct current is supplied to the lamp 4 through 3 and the fuse 5, and the lamp 4 is turned on.

  On the other hand, when the light switch 6 is turned off, the current supply from the battery 1 to the coil 7 of the relay 2 is stopped and the contact 3 of the relay 2 is turned off (opened), and the current supply from the battery 1 to the lamp 4 is supplied. Stops and the lamp 4 is turned off.

  In this way, the lighting / extinguishing of the lamp 4 is controlled only by the ON / OFF of the light switch 6 and no ignition switch is interposed. Therefore, even if the ignition switch is turned off when the driver leaves the vehicle, the lamp 4 remains in the on state when the light switch 6 is in the on state. In the worst case, the battery may run out.

  Therefore, the vehicular lamp extinguishing control device according to the present invention includes, as shown in FIG. 2, a fuse 5 provided in a genuine in-vehicle wiring related to the lamp 4 and a fuse provided in a genuine in-vehicle wiring related to the ACC switch 16. 19 is removed, and the light-off control device 20 incorporating the removed fuse 5 and fuse 19 is connected to genuine in-vehicle wiring using the fuse mounting terminals 8a and 8b and the fuse mounting terminals 18a and 18b.

  A specific circuit configuration of the extinguishing control device 20 is that a fuse 13 removed from the contact 13 of the relay 12 and the genuine in-vehicle wiring between the connecting terminal 11a and the connecting terminal 11b connected to the fuse mounting terminals 8a, 8b of the genuine in-vehicle wiring. 5 is connected in series, and similarly, the coil 14 of the relay 12 and the fuse 19 removed from the genuine in-vehicle wiring are connected in series between the connection terminal 15a and the connection terminal 15b connected to the fuse mounting terminals 18a, 18b of the genuine in-vehicle wiring. It is connected to the.

  At this time, the fuse mounting terminal 18a of the genuine in-vehicle wiring is connected to the ACC switch 16 side of the ignition switch, and the fuse mounting terminal 18b operates when the ACC switch 16 such as an audio, accessory socket, power window, fuel, etc. is turned on. It is connected to the load (device) 17 side.

  In such a circuit configuration, what happens to the state of the lamp 4 (lit or extinguished) with respect to the combination of the state where the light switch 6 is ON or OFF and the state where the ACC switch 16 of the ignition switch is ON or OFF is as follows. I write.

  When both the light switch 6 and the ignition switch ACC switch 16 are ON, current is supplied from the battery 1 to the coil 7 of the relay 2 and the coil 14 of the relay 12, and the contact 3 of the relay 2 and the contact 13 of the relay 12. Are both turned on (conductive). Then, current is supplied from the battery 1 to the lamp 4 via the contact 3 of the relay 2, the contact 13 of the relay 12, and the fuse 5, and the lamp 4 is turned on. In this case, it is a normal lamp lighting mode.

  When either the light switch 6 or the ignition switch ACC16 switch is OFF, the current from the battery 1 is not supplied to either the coil 7 of the relay 2 or the coil 14 of the relay 12, and the contact 3 of the relay 2 or the relay 12 Any one of the contact points 13 is turned off (opened), the supply of current from the battery 1 to the lamp 4 is stopped, and the lamp 4 is turned off.

  When both the light switch 6 and the ignition switch ACC switch 16 are OFF, neither the coil 7 of the relay 2 nor the coil 14 of the relay 12 is supplied with current from the battery 1, and the contact 3 of the relay 2 and the contact of the relay 12 13 are both turned off (opened), the supply of current from the battery 1 to the lamp 4 is stopped, and the lamp 4 is turned off.

  As described above, the lamp 4 is lit only when both the light switch 6 and the ignition switch ACC switch 16 are in the ON state. That is, even if the driver turns on the light switch 6 and leaves the vehicle, if the ignition switch ACC switch is in the OFF state, the lamp 4 is turned off, and the battery does not run out due to forgetting to turn off the lamp. .

  Next, a method of attaching the turn-off control device 20 to the vehicle will be described with reference to the schematic diagrams of FIGS.

  First, in the process of FIG. 3, the fuse (lamp fuse) 5 connected to the lamp and the fuse (audio fuse) 19 connected to the audio of the ACC switch, for example, are searched from the plurality of fuses installed in the fuse box 30.

  In the next step of FIG. 4, the lamp fuse 5 and the audio fuse 19 are removed from the fuse box 30.

  In the next step of FIG. 5, the lamp fuse 5 and the audio fuse 19 removed from the fuse box 30 in the previous step are respectively inserted into the lamp fuse coupler 31 and the audio fuse coupler 32 of the extinguishing control device 20 (FIG. 2). (Refer to the car interior wiring diagram). At this time, the relay 12 is attached to the relay coupler 33.

  In the next step shown in FIG. 6, the lamp fuse connector 35 connected to the lamp fuse 5 and the contact 13 of the relay 12 is inserted into the fuse box 30 at the position where the lamp fuse 5 is removed, and the audio fuse 19 The audio fuse type connector 36 connected to the coil 14 of the relay 12 is inserted into the fuse box 30 at the position where the audio fuse 19 is removed.

  In the last step of FIG. 7, the work is completed by connecting the body ground 40 of the extinguishing control device 20 to the vehicle body ground, and the in-vehicle wiring shown in FIG. 2 is completed.

  The terminal 37 of the lamp fuse 5 and the audio fuse 19 shown in FIG. 8 and the terminal 38 of the lamp fuse connector 35 and the audio fuse connector 36 shown in FIG. It can be attached to and detached from each fuse mounting terminal of the box 30.

  In addition, a semiconductor switching element such as a transistor can be used instead of the relay 12. Specifically, FIG. 10 shows an in-vehicle wiring diagram relating to a lamp when a vehicle lamp extinguishing control device using an FET (N channel) as a semiconductor switching element instead of the relay 12 is mounted on the vehicle.

  The specific circuit configuration of the light extinguishing control device 20 is that the drain (D) -source (S) of the FET 45 and the genuine terminal are connected between the connection terminal 11a and the connection terminal 11b connected to the fuse mounting terminals 8a and 8b of the genuine in-vehicle wiring. The fuse 5 removed from the in-vehicle wiring is connected in series, and the fuse 19 removed from the genuine in-vehicle wiring is connected between the connection terminal 15a connected to the fuse mounting terminals 18a, 18b of the genuine in-vehicle wiring. And the gate (G) of the FET 45 is connected to the connection terminal 15b.

  At this time, the fuse mounting terminal 18a of the genuine in-vehicle wiring is connected to the ACC switch 16 side of the ignition switch, and the fuse mounting terminal 18b operates when the ACC switch 16 such as an audio, accessory socket, power window, fuel, etc. is turned on. It is connected to the load (device) 17 side.

  In such a circuit configuration, when both the light switch 6 and the ignition switch ACC switch 16 are ON, current is supplied from the battery 1 to the coil 7 of the relay 2 and the contact 3 of the relay 2 is in the ON (conductive) state. Thus, a bias voltage is applied between the drain (D) and the source (S) of the FET 45, and at the same time, a positive voltage is applied between the gate (G) and the source (S), and the FET 45 is turned on. Then, current is supplied from the battery 1 to the lamp 4 through the contact 3 of the relay 2, the drain (D) -source (S) of the FET 45, and the fuse 5, and the lamp 4 is turned on. In this case, it is a normal lamp lighting mode.

  When either the light switch 6 or the ignition switch ACC 16 switch is OFF, or when both the light switch 6 and the ignition switch ACC switch 16 are OFF, the FET 45 is in an OFF (non-conducting) state, and the battery 1 The supply of current to the lamp 4 is stopped and the lamp 4 is turned off.

  As described above, in the vehicular lamp extinguishing control device using the FET instead of the relay 12, both the light switch 6 and the ignition switch ACC switch 16 are provided when the vehicular lamp extinguishing control device is mounted on the vehicle. The lamp 4 is lit only when it is in the ON state. That is, even if the driver turns on the light switch 6 and leaves the vehicle, if the ignition switch ACC switch is in the OFF state, the lamp 4 is turned off, and the battery does not run out due to forgetting to turn off the lamp. .

  In particular, by using a semiconductor switching element in place of the relay, it is possible to eliminate noise associated with ON / OFF of the contact during the relay operation, and the comfortable driving environment is not impaired.

  As described above, the lamp 4 is lit only when the light switch 6 and the ignition switch ACC switch 16 are both in the ON state, and the driver turns on the light switch 6 according to the in-car wiring shown in FIGS. If the ACC switch of the ignition switch is in the OFF state even after leaving the vehicle in the state, the lamp 4 is turned off, and the battery will not run out due to forgetting to turn off the lamp.

  3 to 7, the fuse type connector having a terminal having approximately the same shape and dimensions as the fuse can be freely attached to and detached from the fuse mounting terminal after the fuse is removed from the fuse box when retrofitting to the vehicle as an option. Can be plugged in. As a result, it is not necessary to cut the genuine in-vehicle wiring cord when mounting the extinguishing control device on the vehicle, and even if the original wiring state is restored when removed from the vehicle, the restored wiring cord has traces of seams.
