The retainer 22 is made of synthetic resin, and has a plate-shaped base 33 and a main body 34 rising from the front end of the base 33, as shown in FIG. 1, although details are not shown. The upper end portion of the main body portion 34 enters the communication portion of each cavity 25 and is disposed opposite to the rear end of the connecting portion 27 of the terminal fitting 21 . By arranging the main body portion 34 so as to be able to engage with the connecting portion 27, the terminal fitting 21 is secondarily prevented from coming off inside the housing main body 23. As shown in FIG. 9, the base portion 33 is disposed on the lower surface side of the housing body 23 such that displacement thereof is regulated by each corner rib 31, each intermediate rib 32, and the front side of the housing body 23.

As shown in FIGS. 3 and 4, a recess 35 is formed in the middle portion of the upper surface of the housing body 23 in the width direction. The recess 35 has a concave cross-section and is formed over the entire length of the housing body 23 in the front-rear direction. The cavities 25 described above are arranged in equal numbers (four in the case of the first embodiment) on both sides of the housing body 23 in the width direction with the recess 35 interposed therebetween.

The housing 20 has an elastically deformable lock arm 37 that protrudes from the inner bottom surface 36 of the recess 35 at the middle portion of the housing body 23 in the width direction. As shown in FIG. 7, the lock arm 37 is arranged within the range of the recess 35 in the front-back direction and the width direction.

The arm main body 39 extends in the front-rear direction above the retainer mounting hole 28 that opens in the inner bottom surface 36 of the recess 35 . A divided recess 43 is formed in the middle portion of the lock arm 37 in the width direction, extending from the base end portion 38 to the rear portion of the arm body portion 39 .

The lock protrusion 42 is divided into both sides in the width direction via a dividing recess 43 . The upper surface of the release operation section 41 is a pressing surface 44 that is flat in the left-right direction. As shown in FIG. 5, a recess 45 is formed in the rear surface of the lock arm 37 and opens across the arm main body 39 and the release operation section 41. As shown in FIG. The recess 45 has a slit shape long in the width direction on the rear surface of the lock arm 37. As shown in FIG. 1, the lock protrusion 42 and the release operation part 41 are arranged to protrude upward from the upper surface of the housing body 23 (the upper surface opening of the recess 35).

Although not shown, during the fitting process of the housing 20 and the mating housing 80, the lock protrusion 42 interferes with the lock receiving part 84, so that the arm main body part 39 tilts downward with the base end part 38 as a fulcrum. Displace. In other words, the lock arm 37 is elastically deformed downward. When the housing 20 and the mating housing 80 are properly fitted, the lock arm 37 elastically returns, the arm main body 39 returns to its original position, and the lock protrusion 42 engages with the lock receiver 84, as shown in FIG. can be stopped. Thereby, the housing 20 and the mating housing 80 are held in a fitted state.

An insertion recess 46 that penetrates from the inner bottom surface 36 of the recess 35 to the end surface 29 is formed in the middle portion of the housing body 23 in the width direction. The insertion recess 46 has a rectangular notch shape when viewed from the bottom, extends in the front-rear direction, and opens at the rear surface of the housing body 23 . As shown in FIG. 9, the insertion recess 46 is arranged between the intermediate ribs 32 on both the left and right sides in the width direction.

As shown in FIGS. 3 and 5, the housing 20 has an inversion restricting portion 47 at a position downwardly away from the rear end of the lock arm 37 (arm main body portion 39). A connecting portion 48 is provided between the reversing regulating portion 47 and the reversing regulating portion 47 to connect the two portions.

The connecting portion 48 has a prismatic or rectangular plate shape that extends in the vertical direction, and has a rectangular cross-sectional shape that is long in the front-back direction. The longitudinal dimension of the connecting portion 48 is the same as or close to the longitudinal dimension of the release operation portion 41. The upper end of the connecting portion 48 is integrally connected to the lower surface of the rear end portion of the lock arm 37 , and the lower end of the connecting portion 48 is integrally connected to the upper surface of the reversal regulating portion 47 . The lower end portion of the connecting portion 48 that is connected to the reversal regulating portion 47 is inserted into the insertion recess 46 .

The housing main body 23 has a pair of abutment portions 49 on both left and right sides of the insertion recess 46, which partition the inner bottom surface 36 of the recess 35. Each abutment part 49 is arranged at a height position overlapping the lower part of the cavity 25. As shown in FIG. 5, the lower surface of each abutment part 49 (the surface facing one side in the height direction) is a flat one-side abutment surface 51 that is continuous with the surrounding end surface 29 without any step, and It is disposed opposite to one side facing surface 54 of the reversal regulating portion 47, which will be described later. The upper surface of each abutment part 49 (the surface facing the other side in the height direction) is a flat other-side abutment surface 52 that is continuous with the surrounding inner bottom surface 36 without a step, and the rear end of the lock arm 37 in the height direction. It is placed opposite the bottom surface of the section. The space between the lower surface of the rear end of the lock arm 37 and the other side abutment surface 52 of the abutment part 49 allows the lock arm 37 to be elastically deformed during the fitting process of the housing 20 and the mating housing 80. A bending space 53 is formed.

The reversal regulating portion 47 has a rectangular plate shape extending in the width direction, and is connected to the lower end of the connecting portion 48 at the middle portion in the width direction. The front and rear surfaces of the reversal regulating portion 47 are continuous with the front and rear surfaces of the connecting portion 48 without any step difference. The reversal regulating portion 47 is arranged so as to fit within the width of the lock arm 37, specifically within the maximum width of the lock arm 37 (in the case of the first embodiment, within the width of the release operation portion 41). has been done. Furthermore, the reversal regulating portion 47 is arranged so as to fall within the height range of the housing body 23 in the height direction.

A pair of one-side opposing surfaces 54 are formed on the upper surface of the reversal regulating portion 47 on both sides in the width direction across the connecting portion with the connecting portion 48 . Each one-side opposing surface 54 is arranged flat along the front-rear direction and the width direction, and faces the one-side abutment surface 51 of each abutment part 49 in parallel. As shown in FIG. 5, when the lock arm 37 is in its natural state, the distance in the height direction between the opposing surface 54 on one side of the reversal regulating portion 47 and the abutting surface 51 on one side of the abutment stop portion 49 (Height) is made sufficiently smaller than the height of the bending space 53. Note that the rear surfaces of the lock arm 37, the connecting portion 48, the reversal regulating portion 47, and the stop portion 49 are arranged at the same position as the rear surface of the housing body 23 in the front-rear direction or at a position recessed forward from the rear surface of the housing body 23. (See Figures 7 and 8).

As shown in FIG. 3, the housing 20 has a cover portion 55 behind the reversal restricting portion 47. As shown in FIG. The cover portion 55 has a gate-shaped frame shape in plan view and bottom view, and as shown in FIGS. 7 and 8, a pair of arm portions 56 that extend short in the front and rear directions at both ends in the width direction, and It has a cover main body part 57 that extends long and is connected to the rear end part of each arm part 56. The front end of each arm portion 56 is integrally connected to the rear surface of the intermediate rib 32, respectively. The cover main body portion 57 faces the rear surface of the reversal regulating portion 47 in parallel with a gap therebetween, and is arranged to cover the rear surface of the reversing regulating portion 47 from the rear side (rear side in the fitting direction). Note that the gap between the rear surface of the reversal restricting portion 47 and the cover main body portion 57 and the gap between the front surface of the reversing restricting portion 47 and the opposing inner surface of the insertion recess 46 are formed by a lower portion (not shown) forming the retainer mounting hole 28. It can be molded together with the retainer mounting hole 28 using a side moving mold (see FIG. 8).

(Operation of connector)
As described above, after the lock arm 37 is elastically deformed, the housing 20 and the mating housing 80 are held in a fitted state by the lock protrusion 42 being latched to the lock receiving part 84 . While the lock arm 37 is elastically deformed into the bending space 53, the rear end of the lock arm 37 is displaced downward (to one side in the height direction), and the connecting portion 48 integrally connected to the rear end of the lock arm 37 is reversed. The regulating portion 47 is also displaced downward. Here, the insertion portion of the connecting portion 48 into the insertion recess 46 is displaced upward. The separation distance between the reversal regulating portion 47 and the stop portion 49 becomes larger. On the other hand, the distance between the rear end of the lock arm 37 and the stop portion 49 becomes smaller. However, as long as the lock arm 37 is properly elastically deformed during the fitting process of the housing 20 and the mating housing 80, the rear end of the lock arm 37 will not interfere with the stop portion 49.

When the housing 20 and the mating housing 80 in the fitted state are to be separated due to reasons such as maintenance, it is necessary to release the lock between the lock protrusion 42 and the lock receiver 84. In that case, the operator can release the lock by pressing the pressing surface 44 of the release operation part 41 with a finger such as a thumb and pushing down the release operation part 41. In particular, the operator can press down the release operation part 41 while applying a finger other than the finger pressing the pressing surface 44, for example, the index finger, to the covering part 55, thereby releasing the release without touching the reversal regulating part 47. Operation can be performed smoothly.

By the way, in the state before the housing 20 and the mating housing 80 are fitted, a foreign object such as the electric wire 90 is caught on the rear end of the lock arm 37 including the release operation part 41, and the rear end of the lock arm 37 is lifted upward. there is a possibility. However, in the case of the first embodiment, when the rear end portion of the lock arm 37 is about to be lifted upward, the one-side opposing surface 54 of the reversal regulating portion 47 contacts the one-side abutting surface 51 of the abutting portion 49 from below. As a result, upward displacement of the reversal restricting portion 47 is restricted. This also restricts displacement of the rear end portion of the lock arm 37 that is integrally connected to the reversal restriction portion 47. As a result, it is possible to prevent the lock arm 37 from being excessively elastically deformed in the reversal direction.

Furthermore, if the rear end of the lock arm 37 including the release operation section 41 is inadvertently pushed down in a state before the housing 20 and the mating housing 80 are fitted, the rear end of the lock arm 37 will be moved into the deflection space 53. After being properly elastically deformed, it can come into contact with the other side abutment surface 52 of the abutment part 49. Thereby, it is also possible to prevent the rear end portion of the lock arm 37 from being excessively displaced downward.

In the case of the first embodiment, the lock arm 37 is arranged so as to fit within the width of the recess 35, the stop portion 49 defines the inner bottom surface 36 of the recess 35, and the reversal regulating portion 47 is arranged within the width of the recess 35. 49 from below, and is arranged within the width of the lock arm 37. Therefore, according to the first embodiment, it is possible to prevent the connector 10 from increasing in size in the height direction due to the presence of the stop portion 49. Further, it is also possible to avoid increasing the size of the connector 10 in the width direction due to the presence of the reversal regulating portion 47. In particular, since the opening width of the recess 35 does not need to be increased, there is no need to increase the pitch between the cavities 25 located on both sides of the recess 35 in the width direction.

In addition, since each abutment part 49 is arranged in a height range overlapping with each cavity 25, the connector 10 is Enlargement in the height direction can be better suppressed.
Furthermore, since the lock arm 37 comes into contact with the stop portion 49, excessive elastic deformation of the lock arm 37 downward is also prevented. In particular, since a structure for preventing excessive elastic deformation of the lock arm 37 in both the upper and lower directions is provided in the abutment part 49, it is possible to further avoid increasing the size of the connector 10 and to simplify the configuration. .

Since the height of the deflection space 53 is greater than the height between the inversion regulating portion 47 and the abutting portion 49, a state in which the lock arm 37 is normally elastically deformed into the deflection space 53 can be realized without any problem. Furthermore, excessive elastic deformation of the lock arm 37 in the reversal direction can be prevented at an early stage.

Furthermore, when releasing the fitted state between the housing 20 and the mating housing 80, the operator can press the rear end portion of the lock arm 37 downward while placing his or her finger on the cover portion 55, so that the releasing operation can be performed. can be carried out smoothly.
