A conventional locking mechanism includes a locking member 5. The lock member 5 is provided in the recess 40 provided on one end side of the guide portion 14 in the thickness direction (vertical direction) of the connector 1.
It is fitted so as to be movable to the front end portion 41 of the ejector 4.

A part of the lock member 5 projects to the outside of the guide portion 14, and the engagement portion 42 at the lower portion thereof does not restrain the ejector 4 when the lock member 5 is at the upper position thereof, but at the lower position thereof. At some time, the ejector 4 is engaged with the engaging recess 43 inside the tip portion 41 of the ejector 4.
Restrain. Therefore, the upper position is called the unlocked position,
The lower position is called the lock position.

[0005]

According to the above-mentioned connector, the tip portion 41 of the ejector 4 must be arranged at a position where the lock member 5 has escaped. Moreover, since the moving direction of the lock member 5 is the vertical direction, the range required for the operation of the connector becomes large in the vertical direction.

In order to operate the ejector 4 and the lock mechanism on the front surface of the connector having the insertion port for inserting the mating connector, both the ejector 4 and the lock mechanism must be projected from the front surface of the connector. However, in the conventional example, the ejector 4 must be arranged so as to escape the space required by the lock mechanism, and this also increases the outer dimension in the width direction or the height direction of the connector.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a connector with a detachable lock mechanism whose outer dimensions are reduced.

[0008]
