リ、電池１の劣化を招くという問題があった。Conventional Structure and Problems The wiring of a conventional device using a secondary battery is as shown in FIG. 1, in which a battery 1, a load 2, and a switch 3 are connected in series. In such a configuration, if the user forgets to turn off the switch 3, there is a problem that the battery 1 will not be turned on and the battery 1 will deteriorate.

である。OBJECTS OF THE INVENTION The present invention aims to solve the above-mentioned problems, and provides an overdischarge prevention circuit that can prevent battery deterioration due to overdischarge even if the switch is turned on or off.

より接点が開放するようにしたものである。Structure of the Invention The overdischarge prevention device of the present invention connects a load and a relay winding in parallel, connects this load to a secondary battery via the relay contacts, and prevents the current in the winding from decreasing due to a drop in voltage. This causes the contacts to open.
実施例の説明 以上添付図面に基づいてその実施例について説明する。Description of examples The embodiments will be described above based on the accompanying drawings.

が接続されている。In FIG. 2, 11 is a secondary battery, and 12 is a contact point of a relay connected in series with a load 13. The contacts 12 of the relay are closed by energizing the relay winding 16 connected in parallel with the load 13 via a normally closed switch 14. A normally open switch 163 for starting is connected to contact 12 of the relay.

きない。To explain the operation in the above configuration, once the switch 16 is closed, the normally closed switch 1 is connected to the relay winding 16.
Current flows through 4, so that contact 12 is closed. Then, the load 13 is energized, and the coil 16 is also kept energized. To turn off the power to load 13, press switch 1.
4 is activated and turned OFF even momentarily, the current to the winding 16 of the relay is cut off and the contact 12 is opened. If the user forgets to turn off the switch 14 and the power is turned off,
As the voltage of the battery 11 decreases, the current flowing to the relay winding 16 decreases. When the voltage further decreases, the relay contact 12 is opened. In this case, the power supply to the load 13 is cut off, and the power supply to the relay winding 16 is also cut off, so that the battery 11 is completely disconnected from the load, and no over-discharge occurs.

なく、安定に動作するという利点がある。FIG. 3 shows another embodiment, in which the relay winding 16
A constant voltage diode 17 is connected in series with the constant voltage diode 17. In this case, when the voltage of the battery 11 becomes lower than the set voltage of the constant voltage diode 17, no current flows and the contact 12 is opened. When the constant voltage diode 17 is used, the voltage of the battery 11 becomes constant when the contact 12 is opened, and there is an advantage that there is no variation in operation and stable operation is achieved.

を提供できる。Effects of the Invention As is clear from the above embodiments, by connecting the winding of a relay in parallel with the load and connecting the load to the battery through the contacts driven by the winding of the relay, the battery can be reduced from consumption. When the voltage drops, the contacts open, so the battery does not over-discharge or deteriorate, providing a long-life device.
