This can prevent the tabs 42 from being exposed during the process of stacking the housings 21, 22, 23, and 24. After all the housings 21, 22, 23, 24 are stacked, if the last stacked fourth housing 24 on the top layer (one side) and the cover 50 on the top layer (one side) are released, all the covers 50 can be removed from the housing 21, 22, 23, 24.

It is arranged so as to be exposed on the outer surface (upper surface) of 50. According to this configuration, in a state in which all the housings 21, 22, 23, and 24 are stacked, it is possible to easily release the holding between the fourth housing 24, which is the uppermost layer, and the cover 50, which is the uppermost layer. Can be done.

  • the housings 21 , 22 , 23 , 24 and the cover 50 have guide ribs 27 and guides as guide portions that guide the cover 50 to be displaced relative to the housings 21 , 22 , 23 , 24 along a path that does not interfere with the tabs 42 .
  • a groove 63 is formed. According to this configuration, the cover 50 is guided to move along a path that does not interfere with the tabs 42, so that the cover 50 is moved along a path that does not interfere with the tabs 42 during the process of attaching and detaching the cover 50 to and from the housings 21, 22, 23, and 24. Interference can be prevented.
  • the guide path by the guide ribs 27 and the guide grooves 63 is a straight path in the front-rear direction parallel to the protruding direction of the tabs 42. According to this configuration, interference between the cover 50 and the tab 42 can be prevented without increasing the size of the cover 50 in the vertical direction or the horizontal direction. Therefore, the shapes of the housings 21, 22, 23, and 24 and the shape of the cover 50 can be simplified.
  • the housings 21, 22, 23, 24 and the cover 50 have a flat shape with a width larger than a height.

  • the guide groove 63 is formed in the arm portion 60. According to this configuration, in the process of removing the cover 50 from the housings 21, 22, 23, 24, the rear end of the guide groove 63 of the cover 50 separates from the front end of the guide rib 27 of the housing 21, 22, 23, 24. Immediately thereafter, even if the cover 50 tilts in the height direction (vertical direction) or moves in the height direction (vertical direction), the cover part 51 can be prevented from interfering with the tab 42.

  • the plurality of covers 50 are arranged in a stacked manner in the height direction.
  • a positioning recess 56 and a positioning protrusion 57 are formed in the two covers 50 that overlap in a stacked state as positioning parts that restrict relative displacement in the width direction by fitting into each other.
  • the relative displacement of the two covers 50 that overlap each other in the stacked state in the width direction is regulated by the fitting between the positioning protrusion 57 and the positioning recess 56.
  • the cover 50 is formed with jig locking portions 70 that are arranged in the stacking direction with the sub-connectors 11, 12, 13, and 14 stacked together. According to this configuration, when all the housings 21, 22, 23, 24 and all the covers 50 are stacked, the locking grooves 79 of the jig 75 are locked to all the jig locking parts 70. , all the covers 50 can be removed from the housings 21, 22, 23, 24 with one action.
  • the jig locking portion 70 has a protrusion shape in which at least a portion of the area of the arm portion 60 where the guide groove 63 is formed is thickened. According to this configuration, the rigidity of the portion of the cover 50 where the guide groove 63 is formed is increased by the protruding jig locking portion 70. Therefore, it is possible to prevent prying between the guide rib 27 and the guide groove 63 due to deformation of the portion of the cover 50 where the guide groove 63 is formed (the guide portion on the cover 50 side).
