  When the power feeding connector A and the power receiving connector B are unlocked and released after charging, the plunger 6a is instantaneously restored by the coil spring 6b by the demagnetization of the electromagnetic coil 6 and is separated from the lock hole 5c1. The lock is released, and then the primary lock is released (paragraphs [0021] and [0022]).

Japanese Patent No. 2752032

  During charging, a large charging current such as 500 V 100 A flows between the power feeding connector and the power receiving connector. Therefore, as described above, during charging, the power feeding connector cannot be detached from the power receiving connector by the mechanically-actuated double locking means of the primary lock and the secondary lock.

  However, if for some reason the mechanical locking means does not work or if it is not enough to work, there is a possibility that the power supply connector may be accidentally disconnected from the power receiving connector during charging. There is a problem that there is a risk of melting damage, burns, electric shock, etc. of the power receiving connector.

Further, when a solenoid device for preventing the advancement of the unlocking means in a retracted state due to the excitation of the electromagnetic coil is used as the secondary locking means, the coil spring for returning the plunger is small and its elasticity is also small. . Therefore, if the surface of the plunger is damaged while the plunger is protruding, or the pin itself is bent for some reason, the plunger may not be returned.
Then, even after charging, the power feeding connector cannot be detached from the power receiving connector. For example, when the power receiving connector is installed in an automobile, there is a problem that the automobile cannot be used.

b. The lock arm 220 is rotated in the direction of the central axis of the body 10 by the urging force of the coil spring 223, and the locking claw 221 is retracted from the surface of the case 2 and is disengaged from the slide cover 212.
c. The slide cover 212 moves to the front side by the urging force of the coil spring 213, and the locking claw 221 is covered with the slide cover 212 and returns to the state (1).

<Related to power cut off means>
The power supply cutoff means is configured by a protrusion 242 provided at the upper front portion of the trigger element 24 and a detector (in this embodiment, a micro switch 6 as an electric switch) that detects forward and backward movement of the trigger element 24. The
The micro switch 6 has a general configuration in which a contact mechanism that opens and closes is covered with a case, and an actuator 61 is provided on the outside thereof.

  The microswitch 6 is attached to the inner surface of the body 10 so that the actuator 61 operates in contact with a protrusion 242 provided on the upper front portion of the trigger element 24.

  When the trigger element 24 is retracted, the tip of the actuator 61 comes into contact with the protrusion 242 and rides on the protrusion 242, the contact is closed, and the signal of the contact close is sent to the charger side. The charging electricity is supplied to the power supply connector 1.

  When the trigger element 24 that constitutes a part of the primary unlocking means is moving forward or advanced, the tip of the actuator 61 is at the lower edge 243 of the armband 240 and the contact is in an open state. A signal for opening the contact is sent to the charger side, a power supply cutoff device (not shown) on the charger side works, and electricity is not supplied to the power supply connector 1 from the charger side.

  As described above, even when the power feeding connector 1 is erroneously detached from the power receiving connector 3 during charging, the supply of electricity from the charger side is interrupted before causing the arc discharge, and the charging is stopped. For this reason, the power feeding connector 1 can be safely removed.

  In this embodiment, the microswitch 6 is incorporated in the state monitoring line of the power feeding connector 1. The state monitoring line is a line for monitoring secondary lock driving current, connector connection, and the like, and these lines are constantly monitored by a charger. When a current drop or signal interruption occurs, the charger side determines that the power supply connector 1 is damaged or disconnected, and stops charging (does not start charging). Therefore, the occurrence of an abnormality on the power supply connector 1 side is reliably sent to the charger before the connector is pulled out (immediately before), and the safety of work or operation can be ensured.

When the trigger element 24 is retracted due to the operation of the primary locking means, the microswitch 6 is closed and the electromagnetic coil of the solenoid device 4 is excited by the secondary lock driving current from the charger side, and the contact body The plunger 41 protrudes just before the 25 abutment portions 250 and prevents the trigger element 24 from moving forward.
At the end of charging or when the charging is stopped, the secondary lock driving current from the charger side is stopped, the electromagnetic coil is demagnetized, the protruding plunger 41 is pulled back by the spring, the secondary lock is released, and the primary lock continues. Unlock operation can be performed.

However, when the plunger 41 does not return due to some abnormality and the secondary lock is not released, for example, if the power receiving connector 3 is provided on the body of the automobile, there is a problem that the automobile cannot be moved.
In that case, the tip of the tool T is inserted into the groove or hole 513 of the operation portion 512, the release rod 51 is rotated and advanced, and the tip of the plunger 41 is pressed by the pressing tip 511 to forcibly move the plunger 41. Return. Thereafter, the release rod 51 is reversely rotated and retracted to open the path of the contact body 25. As a result, the trigger element 24 is released from the locked state, and thereafter functions in the same manner as in the normal state.
