The normally inserted female terminal fitting 110 is temporarily prevented from coming off by the lance 24. When all the female terminal fittings 110 have been inserted, the retainer 70A is pushed into the final locking position and the retaining portion 74 is opposed to the rear end jaw 115 of the female terminal fitting 110 as shown in FIG. The female terminal fitting 110 is secondarily retained. At this time, since the inclined portions 39 and 76 are chamfered at the opposing edges of the exposed portion 75 of the retainer 70A and the opening of the retainer mounting hole 28, foreign matter such as the electric wire W is prevented from being caught here. Similarly, the male terminal fitting 140 is housed in the cavity 19 of the female housing 10 in a retaining state.

  Subsequently, the female housing 10 is inserted into the through hole 101 formed in the panel 100 from the front surface side to the rear surface side, and the female housing 10 is inserted into the assembly space 91 of the holder 90 on the rear surface side on the rear end side. Insert in a backward-facing state. In the insertion process of the female side housing 10, as shown in FIG. 2, the second plate 34 is inserted into the second plate accommodating recess 93 in a positioned state, whereby the female side housing 10 is displaced in the height direction and the width direction. The holder lock portion 38 is guided to a position corresponding to (directly facing) the holder lock receiving portion 92. When the female housing 10 is properly attached to the holder 90, as shown in FIG. 3, the holder lock portion 38 elastically locks the holder lock receiving portion 92 and the female housing 10 is detached from the holder 90. Is regulated. At this time, as shown in FIG. 5, the abutting end surface 36 of the projecting plate portion 32 is abutted against the front surface of the back wall 97 of the holder 90, and the electric wire W comes into contact with the attachment target and the back plate 97 to move downward. Forced to bend. The bent electric wire W is led out through the housing side electric wire outlet 37 and the electric wire outlet 99. In addition, when the female housing 10 is properly attached to the holder 90, the second plate 34 is restricted from being bent outward by the side wall 94 and inwardly moved by the inner wall 96, as shown in FIG. The bending deformation is restricted, and the second plate accommodating recess 93 is accommodated in a substantially tightly fitted state.

  By the way, in the above case, the electric wire W drawn out from the preceding housing is inserted into the through hole 101 in a bundle because the preceding housing (not shown) is already arranged on the back side of the through hole 101. If so, the housing insertion region in the through hole 101 may be compressed, and the insertion operation of the female housing 10 may be restricted. However, according to the present embodiment, as shown in FIG. 8, the female housing 10 is provided with chamfered portions 14 and 15 at the four corners thereof, and also prevents erroneous fitting on the lower surface which is the short side portion 13. Since the portion 27 is provided, the long side portion 12 and the electric wire W face each other, and the insertion operation to the through hole 101 of the female housing 10 is allowed while avoiding the electric wire W. In particular, since the erroneous fitting prevention part 27 is provided on the lower surface opposite to the upper surface of the housing body 11 from which the lock receiving part 17 is projected, the erroneous fitting preventing part is provided on both sides of the lock receiving part 17. Unlike the case where 27 is provided, the erroneous fitting preventing portion 27 can be provided at a position where interference with the periphery of the through hole 101 can be avoided.

  Subsequently, the male housing 40 is directly opposed to the female housing 10, and the housing body 11 is fitted into the hood portion 42 in this state. At this time, if the female housing 10 is in a proper fitting posture, the gently inclined portion 14 and the steeply inclined portion 15 can slide in conformity with the corresponding gently inclined receiving portion 55 and the steeply inclined receiving portion 56, respectively. The female housing 10 smoothly enters the back side of the hood portion 42 by the guiding action. When the female housing 10 reaches the proper fitting state in this manner, as shown in FIG. 1, the lock portion 50 elastically locks the lock receiving portion 17 and the housings 10 and 40 are held in the disengagement restricted state. The At this time, most of the housing main body 11 is fitted in the hood portion 42, and the entire protruding plate portion 32 is fitted in the holder 90.

  By the way, when the female housing 10 is fitted in a forward / reverse inverted posture, the steeply inclined portion 15 faces the gently inclined receiving portion 55 as shown by a two-dot chain line in FIG. The front end of the housing body 11 abuts the front end of the hood portion 42 (fitting recess 47) so that the portion 14 faces the steeply inclined receiving portion 56, and thus the fitting operation of both the housings 10 and 40 is restricted. Thereby, it is avoided that the female side housing 10 is fitted to the male side housing 40 in the forward / reverse inversion posture.

  Furthermore, if the female housing 10 is forced to be inserted while taking the posture in which the female housing 10 is reversed in the forward and reverse directions as described above, the female housing 10 is rolled around the front and rear axes as shown by a two-dot chain line in FIG. Then, there is a risk of entering the recesses 47 and 48 across the fitting recess 47 and the lock forming recess 48 while taking an oblique posture. However, according to the present embodiment, the female housing 10 in the forward / reverse reversing posture and in the oblique posture interferes with the restricting portion 58 and the further entering operation is restricted. It is more reliably avoided that the male housing 40 is fitted in the posture.

  Further, in the process of fitting the two housings 10 and 40, the erroneous fitting preventing portion 27 slidably enters the erroneous fitting preventing receiving portion 57. The prevention part 27 is accommodated in the erroneous fitting prevention receiving part 57 in a fitted state. At this time, if another female housing 10A is erroneously fitted, the erroneous fitting prevention part 27 does not correspond to the erroneous fitting prevention receiving part 57 and hits the front end of the hood part 42 and beyond. Since the fitting operation is restricted, both housings 10 and 40 are not erroneously fitted.

As described above, according to the present embodiment, the following effects can be obtained.
When the female housing 10 is in the normal fitting posture, the chamfered portions 14 and 15 are adapted to corresponding portions of the hood portion 42 and the fitting operation of both the housings 10 and 40 proceeds without any trouble. On the other hand, when the female housing 10 is in the forward / reverse inverted posture, the chamfered portions 14 and 15 do not match the corresponding portions of the hood portion 42 and the fitting operation of both the housings 10 and 40 is restricted. Therefore, the erroneous fitting of both the housings 10 and 40 is prevented by confirming this state. In this case, since the means for preventing erroneous fitting is constituted by the chamfered portions 14 and 15, the female housing 10 does not become bulky unlike the conventional protrusion, and the male housing 40 is also included. The entire connector is compactly assembled.

  Further, since the chamfered portions 14 and 15 have the steeply inclined portion 15 and the gently inclined portion 14 and the first locking portion 29 is provided close to the inside of the gently inclined portion 14, The area P thickened more than the steeply inclined portion 15 on the inner side is effectively used, and the space efficiency is improved.

  In addition, since the inclined portions 39 and 76 are chamfered at the opposing edges of the exposed portion 75 of the retainer 70 </ b> A and the opening of the retainer mounting hole 28, the electric wire W is caught on the opposing edge of the exposed portion 75. The wire W is prevented from being cut off, and the retainer 70 </ b> A is prevented from inadvertently dropping from the female housing 10.

  In addition, when the female housing 10 is in a forward / reverse inverted posture and an oblique posture protruding inside the lock portion forming recess 48, the housing body 11 interferes with the restricting portion 58 and fits further. Since the operation is restricted, it is possible to avoid a situation in which the female housing 10 enters the hood portion 42 in the forward / reverse inversion posture.

  The misfit preventing portion 27 is provided at a position corresponding to the partition wall 22 that partitions the cavities 19 adjacent to each other on the lower surface of the housing body 11, and is thus connected to the lower surface of the inner wall of the lower cavity 19. Even if the lance 24 is bent and deformed, the arrangement position of the erroneous fitting preventing portion 27 does not change, and the reliability of the erroneous fitting preventing function is improved.

  Further, since the erroneous fitting preventing portion 27 is provided to protrude from the lower surface of the housing body 11 which is the short side portion 13 opposite to the short side portion 13 where the lock receiving portion 17 is provided, the female side housing When 10 is inserted through the through hole 101, a gap formed between the outer surface of the housing body 11 and the inner surface of the through hole 101 is used as an entry space 105 (see FIG. 8) of the erroneous fitting preventing portion 27. The smoothness of the insertion operation to the through-hole 101 is ensured.

  Further, the outer surface of the housing body 11 is provided with a notch 26 that allows the distal end of the lance 24 in a bent state to enter, so that a wall that defines the bending space of the lance 24 need not be provided. Therefore, the female housing 10 can be reduced in height. In this case, since the tip end portion of the lance 24 is exposed through the notch portion 26, the tip end portion of the lance 24 may interfere with foreign matter and be broken or damaged. Since 27 is arranged between the adjacent notch parts 26, it is avoided that a foreign material contacts the incorrect fitting prevention part 27 and interferes with the lance 24.

  Further, a projecting plate portion 32 is provided on the rear surface of the female housing 10 so as to protrude rearward, and the projecting plate portion 32 is inserted and held in the holder 90 from the rear end side. Can be mounted from. In addition, since the protruding plate portion 32 is provided between the rear surface of the female housing 10 and the holder 90 and the electric wire outlet port 99 is formed to open to the holder 90, the electric wire W is formed in the protruding plate portion 32 and the holder 90. A sufficient space can be secured.

  Further, since the wire W can be led out from both the wire lead-out port 99 and the housing-side wire lead-out port 37, forcible bending of the wire W in the protruding plate portion 32 and the holder 90 is restricted, and the degree of freedom in handling the wire W is restricted. Is increased. In addition, since the protruding plate portion 32 includes the first plate 33 and the second plate 34 that is connected in the direction intersecting the first plate 33 and has a free end, the configuration can be simplified.

  Further, since the holder 90 is provided with an inner wall 96 that restricts the inward tilting of the second plate 34 toward the electric wire W, the second plate 34 is deformed by the mounting of the protruding plate portion 32 on the holder 90. Thus, the assembly reliability of the female housing 10 to the holder 90 is improved.

  Further, since the thickness of the protruding plate portion 32 is small due to a request for miniaturization or the like, the protruding plate portion 32 is deformed in the process of mounting the protruding plate portion 32 to the holder 90, and the holder lock receiving portion 92 and the holder lock portion 38 are properly There is a possibility that the locking reliability is lowered due to the displacement from the locked position. However, according to the present embodiment, the protruding plate portion 32 is positioned by inserting the second plate 34 into the second plate accommodating recess 93, and in this state, the locking operation of the holder lock receiving portion 92 and the holder lock portion 38 is performed. Thus, the holder lock receiving portion 92 and the holder lock portion 38 are surely brought to the proper lock position, and the lock reliability is improved.
