Contact is likely to occur, and the holding portion 15 may be damaged and the regulating portion 19 may be mistakenly inserted into the inserting portion 21, and the half-inserted state of the terminal 7 may not be detected.

Therefore, by setting the amount of protrusion of the holding portion 15 from the engaging surface of the locking portion 9 to be small, the holding slope 25 can be included in the contact surface with the regulating portion 19, and the regulating portion 19 can be included in a wide range. It is possible to receive the insertion force, prevent the restricting portion 19 from being inserted into the inserting portion 21, and stably detect the semi-inserted state of the terminal 7.

In such a connector 1, the holding portion 15 engages with the engaging convex portion 13 at the tip of the locking portion 9 on the front side of the locking lance 11 in the bending direction to regulate the displacement of the locking lance 11 in the restoring direction. Is provided, so that it is possible to prevent the locking lance 11 from being displaced in the restoring direction due to the engagement between the engaging convex portion 13 and the holding portion 15.

Therefore, even if an external force such as an electric wire pulling force is applied to the terminal 7 in the terminal accommodating chamber 3 via the electric wire 41, the locking lance 11 does not displace in the restoring direction, and the engaging convex portion 13 of the terminal 7 is not displaced. And the engagement allowance on the engagement surface of the locking lance 11 with the locking portion 9 can be held.

Further, since the connecting portion 5 has an elastic piece 17 which is formed in a box shape into which the locking portion 9 of the restored locking lance 11 can be inserted and is elastically deformable, the locking lance 11 is excessively formed. When restored, the locking portion 9 may interfere with the elastic piece 17 and the elastic piece 17 may be deformed.

However, since the displacement of the locking lance 11 in the restoring direction is restricted by the engagement between the engaging convex portion 13 and the holding portion 15, the locking portion 9 and the elastic piece 17 do not interfere with each other and are elastic. It is possible to prevent the piece 17 from being deformed.

Further, the amount of protrusion of the terminal 7 of the holding portion 15 in the insertion direction into the terminal accommodating chamber 3 is such that the terminal 7 at the tip of the locking lance 11 on the locking slope 23 on the front side in the restoring direction is inserted into the terminal accommodating chamber 3. Since it is set to be smaller than the amount of protrusion in the direction, the overhang of the holding portion 15 can be suppressed to be small in a state where the locking portion 9 and the engaging convex portion 13 are engaged, and the insertion portion 21 of the regulating portion 19 can be suppressed. Does not interfere with insertion into.

Further, in the connector 1, when the terminal 7 is not properly inserted into the terminal accommodating chamber 3, the locking lance 11 is bent and the holding portion 15 is projected to the insertion portion 21 in the bending direction of the locking lance 11. When the restricting portion 19 is inserted into the inserting portion 21, the restricting portion 19 comes into contact with the holding portion 15 and the restricting portion 19 cannot be inserted into the inserting portion 21, so that the terminal 7 is in a half-inserted state. Can be detected.

At the contact between the regulating portion 19 and the holding portion 15, the amount of protrusion of the terminal 7 of the holding portion 15 in the insertion direction into the terminal accommodating chamber 3 is set to be small, so that the regulating portion 19 and the holding slope 25 are set to be small. It is possible to receive the insertion force of the regulating portion 19 in a wide range by bringing it into contact with the terminal 7, and it is possible to stably detect the semi-inserted state of the terminal 7.

In the connector according to the present embodiment, the front holder is attached to the housing to form the connection opening of the terminal accommodating chamber, but the present invention is not limited to this, and the terminal accommodating chamber is not attached to the housing.
