The locking portion 17a of the lock protrusion 17 of the lock arm 16 is locked. In this locked state, the male and female housings 11, 31 are fully fitted, and the female housing 11 is locked in the locking direction L. As shown in FIG. 14, the locking protrusion 24 of the arm portion 23 of the fitting detection member 20 is inserted into the locking hole 17c of the locking protrusion 17 of the lock arm 16 of the female housing 11 and is locked. , the fitting detection member 20 becomes fully locked. By this fully locked state (full locked position) of the fitting detection member 20, proper fitting of the male and female housings 11, 31 is detected. Furthermore, when the fitting detection member 20 is in the final locking position, the step part 26 of the arm part 23 is moved to the lower side of the bridge-shaped central part 18b of the operating part 18, so that the position of the lock arm 16 is is regulated and its displacement is prevented.

Next, the unfitting operation of the male and female housings 11 and 31 (unlocking of the flexible lock arm 16) will be explained.

In the fully locked state of the fitting detection member 20, as shown in FIG. 16, by operating the operating portion 21 of the fitting detection member 20 in the removal prevention direction L, the lock arm 16 can be operated as shown in FIG. A boss portion 19 provided on the portion 18 slides downward along an inclined surface 29 of the protruding wall portion 28. This sliding of the boss portion 19 causes the lock arm 16 to bend and deform downward, thereby releasing the lock between the locking projection 34 of the male housing 31 and the locking projection 17 of the lock arm 16. While the fitting detection member 20 is being operated, the fitting detection member 20 is sliding in the removal prevention direction L on the CPA accommodating portion 13, but the arm portion 23 of the fitting detection member 20, the lock arm 16 of the female housing 11, and The operating section 18 is set to not interfere. Therefore, the fitting detection member 20 can slide on the CPA accommodating portion 13.

In addition, as shown in FIG. 19, in a specification in which the fitting detection member 20 is not used in the female housing 11, as shown in FIG. 18 is manually pressed downward to bend and deform the lock arm 16 downward. This downward flexural deformation of the lock arm 16 releases the lock between the lock projection 34 of the male housing 31 and the lock projection 17 of the lock arm 16, as shown in FIG.

In this way, it is possible to achieve both the unfitting function of the male and female housings 11 and 31 using the fitting detecting member 20 and the manual unfitting function of the operating section 18 of the lock arm 16. By achieving both of these unmating functions, both the male and female housings 11 and 31 can be unmated in both specifications, with and without the mating detection member 20. This eliminates the need for housing, making it possible to share the housing.

Furthermore, when the male and female housings 11 and 31 are uncoupled, the flexible arm part 23 of the fitting detection member 20 is not interposed in the displacement area of the lock arm 16, so the flexible lock arm 16 is Only the repulsive force can be used as the lock (fitting) release force. Furthermore, by making the lock release force the load of only the flexible lock arm 16, there is no need to consider the combination of the flexible arm portion 23 of the mating detection member 20, and a stable lock release force can be achieved. can get. That is, it becomes easy to set the lock release force.

Although this embodiment has been described above, this embodiment is not limited to these, and various modifications can be made within the scope of the gist of this embodiment.

That is, according to the embodiment described above, the rail portion of the fitting detection member is simply inserted into the concave groove portion of the female housing, but the rail portion of the fitting detection member is provided with an engaging projection, and A locking protrusion may be provided in the concave groove. In this case, when the mating detection member is pushed in the final locking direction, the engagement protrusion on the rail portion is locked with the locking protrusion on the groove, and the mating detection member enters the state where the final locking is completed. The proper fitted state of both male and female housings can be reliably detected.
