Half fitting prevention connector

1. A half fitting prevention connector, comprising:

a cylindrical case;

a connector body that is slidably accommodated in a front half part of the cylindrical case and has a signal terminal;

a lever that is rotatably attached to the cylindrical case; and

a release lever having an engaging piece which engages with a locking piece for preventing a returning operation of the lever or the connector in a state that the connector body is fitted with a mating connector by a rotational operation of the lever,

wherein the release lever has a lock hole;

wherein an electromagnetic coil having a plunger is provided on the cylindrical case;

wherein a microswitch for starting charging by a pressing operation of the plunger is provided on the cylindrical case, the plunger being arranged so as to face the microswitch;

wherein the electromagnetic coil is excited by connection between the signal terminal of the connector body and a signal terminal of a mating connector, and thereby moving the plunger toward the microswitch; and

wherein the release lever is rotatable so that the plunger can enter the lock hole to press the microswitch in a state that the connector body is completely fitted with the mating connector and the plunger cannot enter the lock hole in a state that the connector body is half fitted with the mating connector.

2. The half fitting prevention connector according to claim 1 , wherein the release lever can be manipulated by releasing excitation of the electromagnetic coil when the charging is the completed.

3. The half fitting prevention connector according to claim 1 , wherein a lock arm is branched from the release lever; and

wherein the lock hole is formed in the lock arm.
