Auf der Platine 4 des Dosenteils 2 und der Platine 4* des Steckerteils 1 sind mehrere weitere elektronische Bauelemente angeordnet. So ist eine Steuerung zum Ein- und Ausschalten vorgesehen, mindestens eine LED, deren Leuchten davon abhängig ist, ob der Ladevorgang läuft, und wie weit er fortgeschritten ist. Auf der Platine 4 des Dosenteils 2 ist auch eine Elektronik zur Identifizierung der Stromquelle angeordnet.The control line C of the contact 8 is a data line. The data transmitted via the control lines can identify the vehicle or For example, refer to the temperature of a battery or the voltage of individual battery cells. On the board 4 of the socket part 2 and the board 4 * of the connector part 1 more electronic components are arranged. Thus, a control is provided for switching on and off, at least one LED whose lights depend on whether the charging process is running, and how far he has progressed. On the board 4 of the can part 2 and an electronics for identifying the power source is arranged.

Es ist eine Verriegelung 9,10 an dem Dosenteil 2 vorgesehen, die bei vollständiger Verbindung der Ladesteckvorrichtung automatisch in das Steckerteil 1 einrastet. Durch Druck auf den Hebel der Verriegelung 9 wird die Arretierungsnase 10 angehoben und die Verriegelung gelöst.There is a lock 9,10 provided on the socket part 2, which automatically engages in the plug part 1 with complete connection of the charging plug. By pressing the lever of the lock 9, the locking lug 10 is raised and released the lock.

Wie die Figuren 1 a und 4 zeigen, endet die Interlock-Leitung I an dem Magnet- Sensor 3 in dem Dosenteil 2.As shown in FIGS. 1 a and 4, the interlock line I ends at the magnetic sensor 3 in the can part 2.

Die Kontakte 6,6\7,8,8* sind mittels Zahnscheiben 18 auf der Platine 4,4' angeordnet. The contacts 6,6 \ 7,8,8 * are arranged by means of toothed disks 18 on the board 4,4 ' .
