Then, timer operation indicator light 1 to inform the progress of charging
There are two, but this is because the voltage detection relay 10 operates and determines the charging time (charging amount) when the charging progresses and the storage battery terminal voltage rises to approximately 2.4 V / cell after the start of charging. The timer 8 is started to operate, and the timer operation indicator lamp 12 is turned on at this point. This lighting period cannot be confirmed even at midnight, etc., and this confirmation does not make any sense after charging has progressed considerably.
The present invention has been made in view of the above points, and as a condition for completely charging a storage battery, it is possible to easily confirm whether or not the connection of the connector is complete before starting charging. The purpose is to provide a charger.

As shown in FIG. 1, a series circuit including an AC input breaker 6, a contact b 9 of a charging time timer 8, a normally closed contact 14 of a push button switch, and a primary side coil of a power transformer 17 is connected to an AC power supply 3. An indicator lamp 16 indicating that charging is being performed is connected in parallel to the primary coil of the power transformer 17, and a series circuit of the a contact 11 of the voltage detection relay 10 and the timer 8 is connected in parallel with the indicator lamp 16. Is connected in parallel with the timer 8, and a timer operation indicator lamp 12 is connected in parallel to the timer 8. The secondary side of the power transformer 17 is connected to the primary side of the rectifier 18, and the secondary side positive electrode of the rectifier 18 is connected to , The ammeter 19, the DC output breaker 7, and the positive electrode of the charger output connector 4 are connected in series, the negative electrode of the connector 4 is connected to the negative electrode of the rectifier 18, and the primary side of the DC output breaker 7 and the charger output are connected. A voltage detection relay 10 is connected between the negative electrodes of the connector 4, and a series circuit of a normally open contact 13 of the push button switch and a buzzer 15 is connected in parallel with the voltage detection relay 10 to form the charger 1 of the present invention. is doing. The charger 1 and the storage battery 2 of the present invention are connected to the charger output connector 4 and the storage battery side connector 5 so that a charging circuit is formed and the AC power supply 3 is input to the AC input breaker 6 and the DC output. Charging is started by turning on the breaker 7. Here, it is necessary to inform the charger 1 that the connectors 4 and 5 are completely connected and the output breaker 7 is turned on before the start of charging. AC power supply 3
As a circuit for checking whether or not there is an input of, the normally closed contact 14 of the push button switch is provided on the input side of the AC power supply 3, and the circuit in which the normally open contact 13 and the buzzer 15 that are interlocked with the push button switch are connected in series is output as a direct current. It is connected in parallel to the primary side of the breaker 7. By pressing the push button switch 13 before the start of charging, if the concerts 4 and 5 are completely connected and the output breaker 7 is turned on, a current flows through the storage battery 2 as shown by an arrow (→), and the push button switch 13 is turned on. Since the battery voltage is applied to the buzzer 15 and the buzzer 15 sounds only during makeup, it can be confirmed that the charging circuit for the storage battery 2 is completely formed. At this time, even if the AC power supply 3 is input, the AC power supply is shut off by the normally open contact 13 of the push button switch so that the buzzer 15 does not ring with the power from the AC power supply side.

When the voltage rises to the / cell, the voltage detection relay 10 operates, and the a-contact 11 of the detection relay is closed, so that the timer 8 starts the timed operation and the timer operation indicator lamp 12 lights up. When the set time of the timer 8 has elapsed, the b contact 9 of the timer 8 is broken and the charging is stopped and completed. In this embodiment, the buzzer is used as an indicator of the connection state of the connector, but an indicator lamp such as an LED lamp may be used.
