First, a state in which the lever 40 is installed in close contact with the outer surface of the first connector 10 is illustrated in FIG. 5. At this time, the close hook 48 of the lever 40 is in a state of being hooked to the hook hook end 29 of the first housing 12. This state is well illustrated in FIG. The close hook 48 is hooked to the hook hook end 29 through the doped slot 28 so that the lever 40 overcomes the elastic force of the elastic member 24 ′ while the first housing 12 is closed. )

In this state, the second connector 60 is inserted into the first connector 10. When the second connector 60 starts to be inserted, the release jaw 76 of the second housing 62 starts to push the tip of the contact hook 48. That is, when the release hook 76 pushes the contact hook 48 in the state of FIG. 9, the contact hook 48 is separated from the hook hook end 29 and exits from the escape slot 28.

In other words, the lever 40 rotates about the rotation center pin 20 by the restoring force of the elastic member 24 '. As shown in FIG. 6, the lever 40 is rotated by about 90 degrees in the state of FIG. 5. The lever 40 is erected in the state shown in FIG. 6 because the inner side of the elastic member seating end 58 of the lever 40 is hooked to the installation boss 24.

As such, when the lever 40 is rotated 90 degrees with respect to the first housing 12, the slot inlet 55 of the cam slot 54 is inserted into the insertion guide slot 26 of the first housing 12. ) Is matched to Therefore, when the operator continuously inserts the second connector 60 into the first connector 10, the interlocking pin 66 is inserted into the cam slot 54 through the slot inlet 55. At this time, the pin head 70 of the interlocking pin 66 is seated on the step 56 of the cam slot 54 so that the interlocking pin 66 does not fall out of the cam slot 54.

Once the interlocking pin 66 is inserted into the cam slot 54, the operator inserts the second connector 60 into the first connector 10 using the lever 40. When the lever 40 rotates about the rotation center pin 20, the interlocking pin 66 inserted into the cam slot 54 is along the cam slot 54 and the insertion guide slot 26. You are guided. Therefore, the second connector 60 is inserted into the first connector 10. For reference, FIG. 7 illustrates a state in which the lever 40 is rotated about 45 degrees.

In this process, the release jaw 76 which causes the close hook 45 to be released from the hook hanger stage 29 is moved along the escape slot 28. The second insertion guide 72 'of the second housing 62 is moved along the insertion guide channel 26' so that the second connector 60 is correctly inserted into the first connector 10. To guide.

The state in which the lever 40 is completely rotated and in close contact with the outer surface of the first housing 12 is illustrated in FIG. 8. Of course, compared with the state of FIG. 5, the point where the second connector 60 is inserted into the first connector 10 is different.

In a state in which the second connector 60 is coupled to the first connector 10, the lever 40 is connected to the first connector 10, as shown in FIG. 10, as shown in FIG. 10. Combined with. The locking jaw 47 of the lever 40 is engaged with the fastening hook 80 of the second housing 62 so that the lever 40 is in close contact with the outer surface of the first housing 12. do.

At this time, the close hook 48 of the lever 40 enters the hook hanger stage 29 through the dodging slot 28, and the hook hanger stage 29 is already hooked by the second housing 62. Bump 78 is located. Therefore, the close hook 48 is positioned within one end of the doped slot 28 without being hooked to the hook hanger end 29. This state is well illustrated in FIG.

On the other hand, in order to separate the second connector 60 from the first connector 10, the locking jaw 47 is to be separated from the fastening hanger (80). When the latching jaw 47 is separated from the fastening hanger 80, the lever 40 is about to rotate by the elastic force of the elastic member 24 ′. However, the lever 40 is not rotated due to the insertion force of the second connector 60 inserted into the first connector 10. Therefore, when the worker pulls out the second connector 60 from the first connector 10, the lever 40 is rotated while the interlocking pin 66 is moved along the cam slot 54, as described above. The operation proceeds in the reverse order of the process so that the second connector 60 is separated from the first connector 10.
