ことができる。As described above, according to the terminal double locking connector 41 described above, the detection lever 57 is rotatably provided on the terminal locking member 45, and the first fitting recess 6 is provided on the detection lever 57.
5. While the second fitting concave portion 67 is provided, the connector housing 43 is provided with the projection 73 which is selectively fitted in the temporary locking state or the final locking state of the terminal locking member 45, so that the terminal is in the half-inserted state. In this case, the second fitting recess 67 does not match the projection 73,
Since the detection lever 57 is in a state of being greatly lifted obliquely, it is possible to reliably detect the half-inserted state of the terminal as compared with a conventional terminal locking tool slightly projecting from the connector housing.

挿入位置を段階的に規制することができる。As described above in detail, according to the terminal double locking connector according to the present invention, the detection lever is rotatably provided on the terminal locking member, and the detection lever extends between the detection lever and the connector housing. Since the fitting means for temporarily or permanently locking the terminal locking tool is provided, when the terminal is in the half-inserted state, the fitting means does not match, and the detection lever is greatly lifted obliquely. In this state, it is possible to reliably detect the half-inserted state of the terminal. Also, since the fitting means is fitted when the terminal locking tool is temporarily locked, even if a pressing force acts on the terminal locking tool due to an external force during transportation or the like, the terminal locking tool is in the final locking state. Without shifting, it is possible to prevent shifting to final locking other than when necessary. Further, according to the terminal double locking connector in which the fitting means is constituted by the first fitting recess, the second fitting recess, and the projection, the first fitting recess and the second fitting recess are connected to the projection by the terminal. Since the locking devices are arranged side by side in the insertion direction, the terminal locking devices are selectively fitted into a temporary locking state or a full locking state depending on the insertion depth of the terminal locking devices, and the terminal locking devices are selectively fitted. Can be regulated step by step.
