The second cap 100 side has a larger amount of shift in the height position than the first cap 70 side.

Next, the operation of the connector S of this embodiment will be described.
When it is necessary to protect the male tab during transportation or the like, the first cap 70 is attached to the first housing 10 and the second cap 100 is attached to the second housing 40. In this case, the first cap 70 is fitted into the first housing 10 with the first cap lock portions 19 and 76 in the first housing 10 and the first cap 70 facing each other. Then, as shown in FIG. 9, the first cap lock portion 76 on the cap side gets over the first cap lock portion 19 on the housing side, and the first locking projection 77 of the first cap lock portion 76 on the cap side is the housing. The first locking edge 20 of the first cap lock portion 19 on the side is elastically locked. Further, the opposing first locking projection 80 of the opposing first cap lock portion 79 on the cap side elastically locks the opposing first locking edge 24 at the same operation and substantially the same timing. As a result, as shown in FIGS. 3 to 5, the first cap 70 is attached to the first housing 10 in a retaining state.

  Similarly to the above, as shown in FIG. 10, the second cap lock portion 106 on the cap side gets over the second cap lock portion 47 on the housing side, and the second locking projection of the second cap lock portion 106 on the cap side. 107 elastically locks the second locking edge 48 of the second cap lock portion 47 on the housing side. In addition, the opposing second locking protrusion 110 of the opposing second cap lock portion 109 on the cap side elastically locks the opposing second locking edge 52 at the same operation and substantially the same timing. Thereby, as shown in FIGS. 6 to 8, the second cap 100 is attached to the second housing 40 in a retaining state.

  Subsequently, the two housings 10 and 40 are combined with the caps attached. At the time of this combination, the first housing 10 is positioned relatively above the second housing 40, and from this state, the first dovetail portion 43 enters and engages with the second dovetail groove 43, and the first dovetail groove 13. The second portion 42 enters and engages. Then, both the housings 10 and 40 are slid while bringing the side surfaces into sliding contact with each other. When the two housings 10 and 40 reach the normal coupling position, the first housing lock portions 15 and 16 get over the second housing lock portions 45 and 46 and elastically engage with each other in the removal direction. Is fitted to the beam receiving portion 44, and the front and rear second housing lock portions 45, 46 are disposed so as to be able to come into contact with the contact portions 17, 18. The upper end of the second abutment rib 105 of the second cap 100 abuts on the lower end of the contact rib 75, and thereby the two housings 10 and 40 are held in this coupling position in a movement restricted state.

  In the above case, as shown in FIGS. 1 and 2, the second cap 50 and 104 are opposed to the first cap locks 19 and 76 in the width direction on the upper side in the height direction. The second cap lock portion 47 is disposed apart from the portions 19 and 76, and the first relief portions 22 and 74 face the second cap lock portions 47 and 106 in the width direction on the lower side in the height direction. , 106 are spaced apart from each other. The first cap lock portions 19 and 76 and the second cap lock portions 47 and 106 are in a positional relationship overlapping in the width direction, and when viewed from the front, the first cap lock portions 19 and 76 and the second cap lock portions 47 and 106 are overlapped. Are arranged side by side in the height direction. This state is visible from between the first and second hood facing walls 73 and 103.

  Next, prior to fitting with the mating connector, the first cap 70 is removed from the first housing 10 with the housings 10 and 40 being combined. When the first cap 70 is pulled forward, the first cap locking portion 76 on the cap side is elastically bent toward the second relief portions 50 and 104, and the first locking projection 77 is separated from the first locking edge 20. Further, the first cap lock portion 76 on the cap side is pulled forward through the first cap entry groove 21. Further, the opposed first locking projection 80 of the opposed first cap lock portion 79 is also separated from the opposed first locking edge 24 at substantially the same timing. Therefore, the first cap 70 can be easily detached from the first housing 10 only by applying a forward pulling force to the first cap 70.

  Similarly to the above, when the second cap 100 is pulled forward, the second cap lock portion 106 on the cap side is elastically bent toward the first relief portions 22 and 74 as shown in FIG. The portion 107 is separated from the second locking edge 48, and the cap-side second cap lock portion 106 is pulled out in the direction through the second cap entry groove 49. In addition, the opposed second locking projection 110 of the opposed second cap lock portion 109 on the cap side is also separated from the opposed second locking edge 52 at substantially the same timing. Therefore, the second cap 100 can be easily detached from the second housing 40 only by applying a forward pulling force to the second cap 100. Note that the removed first and second caps 70 and 100 can be reused. Further, the cap-side first and second cap lock portions 76 and 106 can be brought into contact with the groove surfaces of the first and second relief grooves 22, 50, 74, and 104 during the deformation of the deformation, thereby causing excessive bending. Being regulated.

  As is apparent from the above description, according to this embodiment, the first cap 70 is attached to the first housing 10, the second cap 100 is attached to the second housing 40, and the first and second housings 10 are in that state. , 40 can be coupled to each other. At this time, the cap lock portions 19, 47, 76, 106 are arranged in the height direction on the side surfaces of the housings 10, 40 in the coupled state, and the counterpart cap lock portions 19, 47, 76, 106 are arranged in the height direction. Since the escape portions 22, 50, 74, 104 are arranged at different levels, the side walls of the first and second caps 70, 100 do not interfere with each other between the side surfaces of both housings 10, 40, and both housings 10 , 40 can be securely coupled.

  Further, the relief portions 22, 50, 74, 104 are arranged apart from the counterpart cap lock portions 19, 47, 76, 106 by the amount of bending of the counterpart cap lock portions 19, 47, 76, 106. Therefore, the bending operation of the cap locking portions 19, 47, 76, 106 on the mating side can be ensured even in a narrow space between the side surfaces of the housings 10, 40.
