Further, the arm portion 47 of the female retainer 25 is deformed back, so that the third locking portion 48 enters the front third locking receiving portion 54 . As a result, the female retainer 25 moves to the locking position with respect to the female housing 36 and is held at the locking position.
  • the identifier 57 cannot be detected by the machine 59 through the viewing window 60. This is because, as shown in FIG. 19, since ribs 29 are formed on the upper and lower edges of the viewing window 60, the identifier 57 can be detected by the machine 59 from the direction indicated by the arrow A. This is because the tip of the rib 29, which is close to the machine 59, is in focus. In other words, an attempt to detect identifier 57 by machine 59 from the direction indicated by arrow A will not bring identifier 57 into focus.

  • the distance between the lower end of the identifier 57 and the machine 59 is less than the distance between the upper end of the identifier 57 and the machine 59. .
  • the horizontal distance between the lower end of the identifier 57 and the upper end of the identifier 57 is within the depth of field of the machine 59 . This allows the whole identifier 57 to be focused upon when the identifier 57 is detected by the machine 59 .
  • the female retainer 25 has a retracted position in which the restricting portion 62 is retracted from the elastic deformation space 43 and a state in which the restricting portion 62 is in the elastic deformation space 43 in a state where the female lance 42 is engaged with the female terminal 37 . Further, as the male connector 12 and the female housing 36 are fitted together, the female retainer 25 moves between the locking position, the female housing 36 and the male connector 12 . and a completion position indicating that the mating is completed. Completion of fitting between the male connector 12 and the female connector 11 can be confirmed by confirming that the female retainer 25 has moved from the locking position to the completion position. As a result, after the male connector 12 and the female connector 11 are mated, there is no need to move the mating assurance member separately, so the efficiency of assembling the female connector 11 can be improved.
