The terminal connection portion 31 is formed with a first locking portion 32 having a recessed lower surface. In the state where the terminal fitting 30 is normally inserted into the cavities 11A and 11B, the lance 18 is locked to the first locking portion 32 from the rear. Further, the rear end edge of the lower surface side of the terminal connection portion 31 is a second locking portion 33 for locking the retainer 40. The front-rear length of the terminal connection portion 31 is the same as or slightly shorter than the front-rear length of the front spaces 11AF, 11BF. The front end portion of the electric wire 35 is connected to the electric wire crimping portion 34 formed at the rear end portion of the terminal fitting 30 by crimping. The terminal fitting 30 is inserted into the terminal insertion port 14 from the rear of the connector housing 10 and inserted into the cavities 11A and 11B.

  The retainer 40 is for retaining the terminal fittings 30 by being locked to the plurality of terminal fittings 30 inserted in the cavities 11A and 11B, and is in a standby position with respect to the connector housing 10 (FIG. 1). -3, 5) and a locking position obliquely upward and forward with respect to the standby position (see FIGS. 4 and 6). The displacement direction of the retainer 40 is an oblique direction with respect to the insertion direction of the terminal fitting 30.

  As shown in FIGS. 1 to 4, 10, and 11, the retainer 40 includes a main body portion 41 and a pair of symmetrical side plate portions 42 projecting upward and backward from the left and right side edges of the main body portion 41. As shown in FIGS. 1 to 4, the cross-sectional shape cut at right angles to the width direction of the main body portion 41 forms a substantially triangular shape that matches the accommodation space 15. In a state where the retainer 40 is assembled to the connector housing 10, the front surface 40F of the main body portion 41 (retainer 40) is parallel to the front wall surface 16 of the housing space 15, and the rear surface of the main body portion 41 faces the guide slope 17. The guided surfaces 43 are parallel to each other with contact or slight clearance.

  As shown in FIG. 10, a plurality of upper retaining portions 44 </ b> A are formed on the upper surface of the main body 41 so as to protrude so as to correspond to the upper cavities 11 </ b> A. As shown in FIG. 4, the upper-stage retaining portion 44 </ b> A is locked from the rear with respect to the second locking portion 33 of the terminal fitting 30 that is normally inserted into the upper-stage cavity 11 </ b> A. The main body 41 is formed with a plurality of through holes 45 penetrating forward and backward so as to correspond to the plurality of cavities 11B in the lower stage. A lower-stage retaining portion 44 </ b> B is formed at the lower opening edge of the through-holes 45. As shown in FIG. 4, the lower-stage retaining portion 44B is locked from the rear with respect to the second locking portion 33 of the terminal fitting 30 that is normally inserted into the lower-stage cavity 11B.

  As shown in FIGS. 5, 6, and 11, the side plate portion 42 has a substantially square shape when viewed from the side. The side plate portion 42 is formed with a guide groove 46 extending in parallel with the guide slope 17 in a state where the retainer 40 is assembled to the connector housing 10. The length direction of the guide groove 46 is parallel to the movement path between the standby position and the locking position of the retainer 40 and the guided surface 43. Further, a locking step portion 47 is formed on the inner surface of the upper end portion of the side plate portion 42 so as to face in the front-rear direction when the retainer 40 is assembled to the connector housing 10.

  The retainer 40 is formed with a relief recess 48 for avoiding interference with the guide portion 19 in a state where the retainer 40 is moved to the locking position. The escape recess 48 is formed on the side of the front end edge of the partition wall 49 that partitions the left and right adjacent through holes 45, and the front end edge of the outer wall 50 that constitutes the through holes 45 at both left and right ends and the outer surface of the main body 41. When viewed from the side, it is cut out in a substantially triangular shape. The upper edge 51 (see FIGS. 5 and 11) of the escape recess 48 is oblique to the insertion direction of the terminal fitting 30 and is parallel to the displacement direction of the retainer 40 when the retainer 40 is assembled to the connector housing 10. Direction. That is, the inclination angle of the upper edge portion 51 with respect to the insertion direction of the terminal fitting 30 is the same as the inclination angles of the first guide slope 21 and the guide slope 17. Further, the lower edge portion 52 (see FIGS. 5 and 11) of the escape recess 48 is inclined with respect to the insertion direction of the terminal fitting 30 in the state where the retainer 40 is assembled to the connector housing 10, and the second guide slope 22. It is almost parallel to.

  1-4, the retainer 40 accommodates the main body 41 in the accommodating space 15 of the connector housing 10, and makes the guided surface 43 contact the guide inclined surface 17 with a slight clearance or a slight clearance. As shown in FIG. 5, the side plate portion 42 is assembled to the connector housing 10 at the standby position in a state where the side plate portion 42 is overlapped with the outer surface of the connector housing 10. The assembled retainer 40 causes the first locking projection 23 to be locked to the upper end of the guide groove 46 and the second locking projection 24 to be locked to the lower end of the guide groove 46. Retained.

  In a state where the retainer 40 is held at the standby position, the front surface 40F of the retainer 40 is parallel to the front wall surface 16 of the accommodation space 15 with a displacement allowable space S as shown in FIGS. opposite. This displacement allowable space S is a space for allowing the retainer 40 to move obliquely upward and forward from the standby position toward the locking position. Since the front-rear dimension of the allowable displacement space S is larger than the protruding dimension of the guide part 19, the front surface 40 </ b> F of the retainer 40 is located further rearward than the protruding end (rear end) of the guide part 19. Specifically, the protruding end (rear end) of the guide portion 19 is located closer to the front wall surface 16 of the accommodation space 15 than the front surface 40F of the retainer 40. The upper-stage retaining portion 44A is retracted below the insertion path so as not to interfere with the terminal fitting 30 inserted into the upper-side cavity 11A, and the lower-stage retaining portion 44B is inserted into the lower-side cavity 11B. In order not to interfere with the terminal fitting 30 to be made, it is retracted below the insertion path.

  With the retainer 40 held in the standby position in this way, the terminal fittings 30 are inserted into the cavities 11A and 11B as shown in FIG. The terminal connection portion 31 of the terminal fitting 30 inserted into the upper cavity 11A passes through the rear space 11AR, the upper space of the main body 41 of the retainer 40, and the displacement allowance space S in order, as shown in FIG. It is inserted into the front space 11AF. The terminal connection portion 31 of the terminal fitting 30 inserted into the lower cavity 11B is inserted into the front space 11BF through the rear space 11BR, the through hole 45 of the retainer 40, and the displacement allowance space S in this order. The normally inserted terminal fitting 30 is held in a retaining state by primary locking by the first locking portion 32 and the lance 18. In a state where the terminal fitting 30 is properly inserted, the second locking portion 33 at the rear end of the terminal connection portion 31 is substantially flush with the front wall surface 16 of the accommodation space 15 (that is, faces the accommodation space 15). Located).

  When all the terminal fittings 30 have been inserted, the retainer 40 is pushed from the standby position to the locking position. At this time, an operating force exceeding the locking force between the lower end of the guide groove 46 and the second locking protrusion 24 is applied, and the side plate portion 42 is elastically deformed outward in the width direction. In the process of moving the retainer 40, the first locking projection 23 is kept in the state of being fitted in the guide groove 46, so that the guided surface 43 is held in sliding contact with the guide inclined surface 17, whereby the retainer 40 is It is possible to translate on the regular movement path along the guide slope 17.

  When the retainer 40 reaches the locking position, as shown in FIG. 6, the lower end of the guide groove 46 is locked to the first locking projection 23, and the locking step 47 is locked to the locking rib 25. By this locking action, the retainer 40 is held at the locking position. Further, as shown in FIG. 4, the retaining portions 44 </ b> A and 44 </ b> B are engaged with the second engaging portions 33 of the corresponding terminal fittings 30 from the rear, so that all the terminal fittings 30 are removed by the retainer 40. Stopped. In other words, the terminal fitting 30 is reliably held in the retaining state by the primary locking action by the lance 18 and the secondary locking action by the retainer 40.

  When the retainer 40 is held at the locking position, the front surface 40F of the retainer 40 comes into contact with or approaches the front wall surface 16 of the accommodation space 15. Further, the guide portion 19 is fitted (accommodated) in the escape recess 48, the first guide slope 21 faces the upper edge portion 51 of the escape recess 48 in surface contact or close proximity, and the first guide slope 21. Is in a state of being in surface contact with or approaching the upper edge 51 of the recess 48. Further, since the inclination direction of the first guide slope 21 and the upper edge portion 51 of the escape recess 48 is parallel to the moving direction of the retainer 40, the guide portion 19 is inserted into the escape recess 48 when the guide portion 19 is fitted into the retainer 40. Without being interfered with the front surface 40F, the air is smoothly released and fitted into the recess 48.

  When the terminal fitting 30 is inserted while the retainer 40 is held at the standby position, the insertion posture of the terminal fitting 30 may be inclined due to the clearance between the rear spaces 11AR, 11BR of the cavities 11A, 11B and the terminal fitting 30. is there. As one form thereof, as shown in FIG. 2, it is conceivable that the front end portion of the terminal fitting 30 inserted into the upper cavity 11 </ b> A is inclined downward when entering the displacement allowable space S. However, in the present embodiment, since the guide portion 19 is waiting in the displacement allowable space S, the front end portion of the terminal fitting 30 is in contact with (supported) the upper surface (first guide slope 21) of the guide portion 19. This prevents further inclination of the posture.

  In addition, since the upper surface of the guide portion 19 that supports the front end portion of the terminal fitting 30 is a first guide slope 21 that is inclined upward toward the front, the insertion of the terminal fitting 30 advances as the first fitting slope 21 increases. The inclination of the posture is gradually corrected by the inclination of the guide slope 21, and the front end portion of the terminal fitting 30 can enter the front space 11 AF without interfering with the front wall surface 16 of the accommodation space 15. Moreover, in the state where the retainer 40 is displaced to the locking position, the guide portion 19 is accommodated in the escape recess 48 of the retainer 40, so that the front surface 40F of the retainer 40 and the front wall surface 16 of the accommodating space 15 There is no dead space in between.

  Further, when the inclination angle of the first guide slope 21 with respect to the insertion direction of the terminal fitting 30 is set to be smaller than the inclination angle of the movement path of the retainer 40 with respect to the insertion direction of the terminal fitting 30, the retainer 40 is locked. When the displacement is made, the dead space is vacated between the upper edge portion 51 (inner surface) of the escape recess 48 and the first guide slope 21. In this respect, in the present embodiment, the inclination angle α of the first guiding slope 21 is the same as the inclination angle α of the movement path of the retainer 40, so that the upper edge portion 51 of the escape recess 48 and the first guiding slope 21 There is no need to leave dead space between.

  Moreover, the guide part 19 protrudes from the partition part 20 which divides the upper and lower adjacent cavities 11A and 11B, and the upper guide first guide is provided in the guide part 19 so as to correspond to the adjacent cavities 11A and 11B. Two guide slopes, the slope 21 and the second guide slope 22 for the lower stage, are formed. Therefore, when the terminal fitting 30 inserted into the lower cavity 11B is inclined upward, the inclination of the attitude is corrected by the second guiding inclined surface 22.
