Description of the Related Art Generally, a terminal receiving chamber in a connector housing is provided with a flexible locking arm (lance) for preventing the terminal from slipping back. However, the size of the flexible locking arm is limited by the multi-polarity and miniaturization of the connector, so that a sufficient terminal locking force may not be exhibited. One of the solutions to such a problem is a terminal double locking connector in which locking means is provided separately from the flexible locking arm and the strength of the terminal is double-locked by double locking.

Is in a temporarily locked state. In this state, the terminal 11 can be inserted from behind the connector housing 1. When the terminal 11 is inserted into the terminal accommodating chamber 3, the flexible locking arm 31 (see FIG. 8) in the terminal accommodating chamber 3 engages with the shoulder 33 of the terminal 11 to temporarily lock the terminal 11. In this state, when the terminal locking member 7 is further pushed in, as shown in FIG. 7B, the second locking projection 19 moves over the second engaging portion 27 to the final locking position, The locking portion 15 is engaged with the locking hole 13 to achieve double locking of the terminal 11. Further, according to the terminal double locking connector 29, when the terminal 11 is not inserted into the predetermined position, the terminal locking portion 15 does not engage with the locking hole 13 and the terminal locking member 7 is removed from the connector housing 1. Since the terminal 11 is in the protruding state, the half-inserted state of the terminal 11 can also be detected.

供を目的とするものである。However, in the above-described conventional terminal double locking connector 29, even if the terminal 11 is in a half-inserted state in the terminal accommodating chamber 3, the terminal locking member 7 is connected to the connector housing. If you force it into 1,
Since the terminal 11 bites into the terminal locking portion 15 and the terminal locking tool 7 is pushed in while slightly protruding from the connector housing 1, it is erroneously recognized that the terminal locking tool 7 is fully locked. There is a problem in that the half-inserted state of the terminal 11 cannot be easily detected. Further, in the terminal double locking connector 29 described above, the terminal locking tool 7 may be handled in a temporary locking state, but the terminal locking tool 7 is changed from the temporary locking to the final locking by a pressing force in one direction. And the terminal lock 7 is easily brought into the final lock state by an external force during transportation or the like, and it is necessary to return the terminal lock 7 to the temporary lock state again in the assembly process. there were. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to reliably detect a terminal half-inserted state, and to prevent a terminal locking tool from easily transitioning to a fully locked state by an external force during transportation or the like. It is an object of the present invention to provide a heavy locking connector.

Is temporarily locked. In this state, since the fitting means is fitted, even if a pressing force acts on the terminal locking tool by an external force during transportation or the like, the terminal locking tool does not shift to the full locking state. In the provisionally locked state of the terminal locking member, the terminal is inserted, the detection lever is rotated to release the fitting of the fitting means, and the terminal locking tool is further pushed in, the fitting means is fully locked. At the same time, the terminal locking portion is engaged with the terminal, and the double locking of the terminal is achieved. Next, by rotating the lever portion, the fitting means is fitted, and the terminal locking tool is fully locked to the connector housing. At this time, if the terminal is in a half-inserted state with respect to the terminal accommodating chamber, the terminal locking member does not enter the hollow portion to the predetermined position, the fitting means does not match, and the detection lever is moved by the swing member. The lower end is at a position far away from the projection, the lever part is lifted up diagonally, and the half-inserted state of the terminal is detected. In 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 terminal-locked to the projection. The terminal locking tool is selectively fitted in the temporary locking state or the final locking state, which is arranged side by side in the insertion direction of the locking tool and differs depending on the insertion depth of the terminal locking tool. Regulations can be made step by step.

Do not enter 49. Then, the second fitting recess 67 does not coincide with the projection 73, and the projection 69 and the projection 73 come into contact with each other (the state shown in FIG. 3).
9 is located far away from the projection 73, and FIG.
As shown in (C), the distal end 61a of the lever portion 61 remains in an obliquely lifted state. That is, the half-inserted state of the terminal is detected by the state in which the lever 61 is lifted.

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.

Even if the pressing force acts on the stopper 45, the terminal locking member 45 does not shift to the final locking state.

1 may be provided with a projection 73 on the detection lever 57 and a first fitting recess 65 and a second fitting recess 67 on the connector housing 43. Further, in the above-described embodiment, an example in which the detection lever 57 is provided with the pair of swing members 59, 59 has been described. However, the detection lever 57 may have at least one swing member 59. Further, the swinging member may not be a side plate but may be rotatably built in the locking body 53.

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.
