     DETAILED DESCRIPTION 
     In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. 
     Description of Embodiments of Present Disclosure 
     First, embodiments of the present disclosure are listed and described. 
     (1) The connector of the present disclosure includes a housing body provided with a cavity for accommodating a terminal fitting, a front mask to be mounted on a front surface of the housing body, and a lock arm extending rearward from a base end portion fixed to the housing body, the front mask including a locking portion to be locked to the base end portion. According to this configuration, a width of the housing body can be made smaller as compared to the case where locking structures are provided on both left and right sides of the front mask. Therefore, enlargement in a width direction can be suppressed. 
     (2) Preferably, the locking portion of the front mask is resiliently deformable in a front-rear direction and exposed to outside of the housing body with the locking portion locked to the base end portion. According to this configuration, the enlargement of the housing body can be suppressed as compared to the case where a deflection space for the locking portion of the front mask is provided inside the housing body. 
     (3) The front mask may include a body portion to be put on the front surface of the housing body with the front mask mounted on the housing body, and a rear end of the locking portion may be located forward of a rear surface of the body portion. According to this configuration, the locking portion of the front mask is not in contact with the front surface of the housing body when the front mask is mounted by being moved in a direction parallel to the front surface of the housing body. Therefore, the front mask can be easily mounted on the housing body as compared to the case where the locking portion of the front mask contacts the front surface of the housing body in mounting the front mask on the housing body. 
     (4) The housing body may include a housing-side guide portion extending along the front surface of the housing body, and the front mask may include a mask-side guide portion configured to contact the housing-side guide portion from behind. According to this configuration, the front mask can be easily mounted on the housing body by bringing the mask-side guide portion into contact with the housing-side guide portion from behind and pushing the front mask in a moving direction. 
     (5) A recess may be formed in a front surface of the base end portion, and the locking portion may be fit into the recess with the locking portion locked to the base end portion. According to this configuration, since a projecting dimension of the locking portion from the housing body can be made smaller as compared to the case where the locking portion is not fit into the recess, the locking portion can be protected. 
     (6) The front mask may have a stopper surface, and the base end portion may have a first receiving surface to be locked to the locking portion and a second receiving surface oriented downward toward a side opposite to the first receiving surface and facing the stopper surface. According to this configuration, if the front mask is moved when being mounted on the housing body, the front mask can be stopped at a correct position by the stopper surface of the front mask and the second receiving surface of the base end portion. Since the first and second receiving surfaces are both provided on the base end portion of the lock arm, the enlargement of the housing body can be suppressed.

The left and right ribs  18  are parallel. Parallel does not mean parallel in a strict sense, but means that two extend side by side. Front end parts of the ribs  18  project upward from the bottom surface of the recessed portion  17 . The upper surfaces of the ribs  18  are located above the upper surface  20 A of the lock arm  20  except the lock projection  22  and the operating portion  23  (see  FIG. 3 ). 
     As shown in  FIG. 3 , the base end portion  21  is arranged in a front end part of the housing body  10 . The base end portion  21  is provided with a locking step portion  24 . The upper surface of the locking step portion  24  is located below the upper surface  20 A of the lock arm  20 . A lower inclined surface  25  is formed on the lower surface of the locking step portion  24 . The lower inclined surface  25  contacts a later-described locking portion  42  of the front mask  40  to guide the resilient deformation of the locking portion  42  in mounting the front mask  40  on the housing body  10 . 
     As shown in  FIG. 4 , the locking step portion  24  has a first receiving surface  26  and a second receiving surface  27 . The locking portion  42  of the front mask  40  is locked to the first receiving surface  26  (see  FIG. 5 ). The first receiving surface  26  is formed on the upper surface of the locking step portion  24 . 
     The second receiving surface  27  is facing a stopper surface  45  of the front mask  40  (see  FIG. 5 ). The second receiving surface  27  is formed on the lower surface (surface opposite to the first receiving surface  26 ) of the locking step portion  24 . The second receiving surface  27  is provided behind the lower inclined surface  25 . 
     As shown in  FIG. 6 , protection walls  19  are provided on both left and right sides of the locking step portion  24 . The left and right protection walls  19  are connected to the front end parts of the left and right ribs  18 . The left and right protection walls  19  project further forward than the front surface of the locking step portion  24 . The front surfaces of the protection walls  19  and that of the housing body  10  in the second regions  16  are aligned in the front-rear direction. The upper surfaces of the protection walls  19  are located above the first receiving surface  26  of the locking step portion  24 . The lower surfaces of the protection walls  19  constitute parts of the second receiving surface  27 . 
     As shown in  FIG. 6 , a recess  28  is formed in front of the locking step portion  24 . The recess  28  is recessed rearward from the front surfaces of the protection walls  19 . Both upper and lower sides of the recess  28  are open. 
     As shown in  FIGS. 2 and 6 , a fitting recess  30  is provided in the front surface of the housing body  10 . The front mask  40  is fit into the fitting recess  30 . Front and lower sides of the fitting recess  30  are open. An upper side of the fitting recess  30  communicates with the recess  28  except a part closed by the second receiving surface  27 . The front mask  40  is fit into the fitting recess  30  from below. In mounting the front mask  20  on the housing body  10 , the front surface of the front mask  40  moves in the vertical direction (direction parallel to the front surface of the housing body  10 ) along the front surface of the housing body  10 . 
     The fitting recess  30  is formed in the front surface of the housing body  10  in the first region  15 . By forming the fitting recess  30 , the front surface of the housing body  10  in the first region  15  is located behind the front surface of the housing body  10  in the second regions  16 . 
     As shown in  FIG. 2 , the fitting recess  30  is provided at a position near one side (left side) in the lateral direction. A lateral center position of the fitting recess  30  is shifted leftward from that of the housing body  10 . Thus, the base end portion  21  of the lock arm  20  is arranged to the right of the lateral center position of the fitting recess  30 . 
     As shown in  FIG. 6 , the housing body  10  includes housing-side guide portions  31 . The housing-side guide portions  31  are provided on both left and right sides of the fitting recess  30 . The housing-side guide portions  31  extend in the vertical direction along the front surface of the housing body  10  in the second regions  16 . 
     The housing-side guide portions  31  are facing away from the front surface of the housing body  10  in the first region  15 . Groove portions  32  are formed between the housing-side guide portions  31  and the front surface of the housing body  10  in the first region  15  (see  FIG. 4 ). The lower ends of the groove portions  32  serve as entrances for mask-side guide portions  52 . The housing-side guide portions  31  and the groove portions  32  have housing-side guide surfaces  33 . The housing-side guide surfaces  33  extend in the vertical direction. 
     As shown in  FIG. 2 , the housing-side guide portion  31  includes a lower guide portion  31 A and an upper guide portion  31 B. The lower guide portion  31 A has a larger vertical dimension than the upper guide portion  31 B. The upper guide portion  31 B has a larger lateral dimension than the lower guide portion  31 A. In this way, the front mask  40  can be stopped in contact with the lower surfaces of the upper guide portions  31 B. 
     The front mask  40  includes a body portion  41  and the locking portion  42 . The body portion  41  is put on the front surface of the housing body  10  in the first region  15  to cover front sides of the locking lances  12  as shown in  FIG. 3  with the front mask  40  mounted on the housing body  10 . The locking portion  42  is locked to the base end portion  21 . 
     As shown in  FIG. 5 , the body portion  41  is formed with tab insertion openings  43  and front end accommodating portions  44 . The tab insertion openings  43  and the front end accommodating portions  44  are arranged in front of the first cavities  13  with the front mask  40  mounted on the housing body  10 . Front end parts of the small terminal fittings T are accommodated into the front end accommodating portions  44 . The small terminal fittings T are stopped in contact with the front surfaces (back surfaces) of the front end accommodating portions  44 . 
     As shown in  FIG. 5 , the body portion  41  has the stopper surface  45 . The stopper surface  45  is provided on the upper surface of the body portion  41  (front side in a moving direction of the front mask  40 ). As shown in  FIG. 7 , the stopper surface  45  extends in the lateral direction up to both left and right ends of the body portion  41 . 
     As shown in  FIG. 7 , the body portion  41  has a rectangular shape when viewed from front. The body portion  41  is in the form of a thick plate along the front surface of the housing body  10  in the first region  15 . The body portion  41  is closely fittable into the fitting recess  30  (see  FIG. 6 ). That is, a vertical dimension, a width (lateral dimension) and a thickness (front-rear dimension) of the body portion  41  are equal to those of the fitting recess  30 . 
     As shown in  FIG. 7 , the locking portion  42  is provided on the upper surface of the body portion  41 . The locking portion  42  stands upward from the upper surface of the body portion  41 . The locking portion  42  is arranged at a position closer to one side (right side) than a lateral center of the body portion  41 . 
     As shown in  FIG. 8 , the locking portion  42  includes an extending portion  46  and a locking projection  47 . The extending portion  46  is in the form of a wall projecting upward from the upper surface of the body portion  41 . The extending portion  46  is resiliently deformable in the front-rear direction. The extending portion  46  is arranged on a front side of the upper surface of the body portion  41 . The stopper surface  45  is formed behind the extending portion  46  on the upper surface of the body portion  41 . A front inclined surface  48  is formed on the upper surface of the extending portion  46 . As shown in  FIG. 5 , the front inclined surface  48  is located on the front end of the connector C with the front mask  40  mounted on the housing body  10 . The front inclined surface  48  guides connection to the unillustrated mating connector. 
     As shown in  FIG. 8 , the locking projection  47  is provided on an upper end part of the extending portion  46 . The locking projection  47  projects rearward from the rear surface of the extending portion  46 . The rear end of the locking projection  47  (rear end of the locking portion  42 ) is located forward of the rear surface of the body portion  41 . A width (lateral dimension) of a locking surface  49  is equal to that of the extending portion  46 . 
     As shown in  FIG. 5 , the locking projection  47  has the locking surface  49  to be locked to the first receiving surface  26 . The locking surface  49  is provided on the lower surface of the locking projection  47 . The locking surface  49  is facing the stopper surface  45  in the vertical direction. The upper surface of the locking projection  47  has a rear inclined surface  51 . The rear inclined surface  51  contacts the lower surface of the locking step portion  24  to guide the resilient deformation of the locking portion  42  in mounting the front mask  40  on the housing body  10 . An upper end part of the locking portion  42  is tapered by the front inclined surface  48  of the extending portion  46  and the rear inclined surface  51  of the locking projection  47 . 
     As shown in  FIG. 6 , the front mask  40  includes the mask-side guide portions  52 . The mask-side guide portions  52  are positioned behind the housing-side guide portions  31 . The mask-side guide portions  52  are movable in the vertical direction with respect to the housing-side guide portions  31  with the mask-side guide portions  52  inserted in the housing-side guide portions  31 . 
     As shown in  FIG. 7 , the mask-side guide portions  52  are provided on both left and right sides of the body portion  41 . The mask-side guide portions  52  extend in the vertical direction. The mask-side guide portions  52  are formed on a rear surface side of the body portion  41  (see  FIG. 8 ). Stepped recesses  53  are formed in front of the mask-side guide portions  52 . As shown in  FIG. 6 , the stepped recesses  53  are so shaped that the housing-side guide portions  31  are fit thereinto. 
     The mask-side guide portions  52  and the stepped recesses  53  have mask-side guide surfaces  54 . The mask-side guide surfaces  54  extend in the vertical direction. The mask-side guide surfaces  54  contact the housing-side guide surfaces  33 . In this way, the front mask  40  is efficiently guided when moving to be mounted on the housing body  10 . 
     As shown in  FIG. 7 , the mask-side guide portion  52  includes a lower guide portion  52 A and an upper guide portion  52 B. The lower guide portion  52 A has a larger vertical dimension than the upper guide portion  52 B. The lower guide portion  52 A has a smaller lateral dimension than the upper guide portion  52 B. The upper guide portion  52 B is located behind the upper guide portion  31 B of the housing-side guide portion  31  (see  FIG. 6 ). The lower guide portion  52 A is positioned behind the lower guide portion  31 A of the housing-side guide portion  31 . 
     Next, an example of an operation of mounting the front mask  40  on the housing body  10  is described. As shown in  FIG. 6 , upper end parts of the mask-side guide portions  52  are inserted into the lower ends of the groove portions  32  of the housing body  10 . The housing-side guide portions  31  and the mask-side guide portions  52  come into contact with each other in the front-rear direction. In this way, the front mask  40  is restricted from moving from the fitting recess  30  in the front-rear direction and lateral direction. 
     Subsequently, the front mask  40  is moved upward. The front mask  40  is guided upward toward a proper mounting position by the contact of the mask-side guide surfaces  54  and the housing-side guide surfaces  33 . When the front mask  40  moves, the rear end of the locking projection  47  is not in contact with the front surface of the housing body  10 . When the front mask  40  moves, the rear surface of the body portion  41  is proximate to or in contact with the front surface of the housing body  10 . 
     Eventually, the rear inclined surface  51  of the locking portion  42  contacts the lower inclined surface  52  of the locking step portion  24  from below. Subsequently, the locking portion  42  is resiliently deformed forward by the inclination of the rear and lower inclined surfaces  51 ,  52 . The locking projection  47  rides on a front side of the locking step portion  24 . 
     Thereafter, as shown in  FIG. 5 , the front mask  40  reaches the proper mounting position. The stopper surface  45  of the front mask  40  contacts the second receiving surface  27 . In this way, the front mask  40  is restricted from moving upward beyond the proper mounting position. The locking projection  47  rides over the locking step portion  24 . The locking portion  42  is displaced forward with a resilient force. Thereafter, the locking portion  42  resiliently returns (returns to a natural state) and is fit into the recess  28  (see  FIG. 1 ). In the state fit in the recess  28 , the locking portion  42  is exposed to the outside of the housing body  10 . The upper surface of the locking portion  42  fit in the recess  28  is located below the upper surfaces of the protection walls  19  (see  FIG. 3 ). The locking surface  49  is locked to the first receiving surface  26 . The locking portion  42  of the front mask  40  is locked to the base end portion  21 . In this way, the front mask  40  is restricted from moving downward (being separated) from the proper mounting position. In the above way, the operation of mounting the front mask  40  on the housing body  10  is completed. 
     Next, functions and effects of the embodiment configured as described above are described. The connector C includes the housing body  10 , the front mask  40  and the lock arm  20 . The plurality of cavities  11  are provided inside the housing body  10 . The front mask  40  is mounted on the front surface of the housing body  10 . The lock arm  20  extends rearward from the base end portion  21  fixed to the housing body  10 . The front mask  40  includes the locking portion  42  to be locked to the base end portion  21 . According to this configuration, the width of the housing body  10  can be made smaller as compared to the case where locking structures are provided on both left and right sides of the front mask  40 . Further, the base end portion  21  of the lock arm  20  can be utilized as a locking part for the front mask  40 . Therefore, the enlargement of the connector C in the width direction can be suppressed. 
     The locking portion  42  of the front mask  40  is resiliently deformable in the front-rear direction. The locking portion  42  is exposed to the outside of the housing body  10  with the locking portion  42  locked to the base end portion  21 . According to this configuration, the enlargement of the housing body  10  can be suppressed as compared to the case where a deflection space for the locking portion  42  of the front mask  40  is provided inside the housing body  10 . Further, a locked state of the locking portion  42  of the front mask  40  and the base end portion  21  can be visually confirmed. 
     The front mask  40  includes the body portion  41  to be put on the front surface of the housing body  10  with the front mask  40  mounted on the housing body  10 . A moving direction of the front mask  40  in mounting the front mask  40  on the housing body  10  is a direction parallel to the front surface of the housing body  10 . The rear end of the locking portion  42  is located forward of the rear surface of the body portion  41 . According to this configuration, the locking portion  42  of the front mask  40  is not in contact with the front surface of the housing body  10  in mounting the front mask  40  on the housing body  10 . Therefore, the front mask  40  can be easily mounted on the housing body  10  as compared to the case where the locking portion  42  of the front mask  40  is in contact with the front surface of the housing body  10  in mounting the front mask  40  on the housing body  10 . 
     The housing body  10  includes the housing-side guide portions  31 . The front mask  40  includes the mask-side guide portions  52 . The mask-side guide portions  52  are located behind the housing-side guide portions  31  and movable in the vertical direction with respect to the housing-side guide portions  31 . According to this configuration, the front mask  40  can be easily mounted on the housing body  10  by inserting the mask-side guide portions  52  behind the housing-side guide portions  31  and pushing the front mask  40  in the moving direction. 
     The base end portion  21  is formed with the recess  28 . The locking portion  42  is fit into the recess  28  with the locking portion  42  locked to the base end portion  21 . According to this configuration, a projecting dimension of the locking portion  42  from the housing body  10  can be made smaller as compared to the case where the locking portion  42  is not fit into the recess  28 . Thus, the locking portion  42  can be protected from contact with external matters and the like. 
     The front mask  40  has the stopper surface  45 . The base end portion  21  has the first and second receiving surfaces  26 ,  27 . The locking portion  42  is locked to the first receiving surface  26 . The second receiving surface  27  is oriented toward a side opposite to the first receiving surface  26  and facing the stopper surface  45 . According to this configuration, if the front mask  40  moves in mounting the front mask  40  on the housing body  10 , the front mask  40  can be stopped at a correct position by the stopper surface  45  of the front mask  40  and the second receiving surface  27  of the base end portion  21 . Since the first and second receiving surfaces  26 ,  27  are both provided on the base end portion  21  of the lock arm  20 , the enlargement of the housing body  10  can be suppressed as compared to the case where receiving surfaces are provided on left and right sides.
