Twist. The twisting direction is a direction in which the fragile portion S described above is bent outward.

  When the connector 10 is twisted in this way, as shown in FIGS. 2 and 10, the fragile portion S of the slide rails 21 </ b> A and 21 </ b> B receives lateral force and breaks from the lower wall surface 10 a to bend, thereby locking the lock portion 22. , 42 are disengaged from each other, or the remaining lateral walls 23b, 43b are disengaged from each other.

  Therefore, when the lock portions 22 and 42 are disengaged from each other, the slide rails 21A and 21B are twisted so that the lock portions 22 and 42 are not locked again, and the slide rails 21A and 21B are moved to the mating slide rail. The connector 10 can be easily detached if it comes out of 41A and 41B. When the remaining horizontal walls 23b and 43b are disengaged from each other, as shown in FIG. 4, the connector 10 can be easily removed by lifting the connector 10 as it is. Therefore, the removal work can be performed without a tool.

  In the present embodiment, the slide rails provided with the fragile portion S are the slide rails 21A and 21B that are engaged from the outside. Therefore, it is necessary to determine the slide rail interval in consideration of the bending space of the inner slide rails 41A and 41B. The distance between the slide rails 21A, 21B, 41A, 41B can be set small.

  In the above embodiment, the weakened portion S (the portion denoted by reference numeral 23a) is bent from the lower wall surface 10a of the connector 10 and bent outward when a certain level of lateral rigidity is applied. As shown in FIG. 3, a slit (notch) 23f may be formed in advance under the vertical wall 23a forming the weakened portion S so that the weakened portion S can be easily bent outward. Moreover, in the said embodiment, although the weak part S was provided in slide rail 21A, 21B engaged from the outer side, the same weak part S can also be provided in step 41A, 41B engaged from the inner side instead. .
