The strength of both end portions of the root portion of the portion can be improved.

  In the third characteristic configuration, the posts disposed at both ends are flat plate-shaped, and the high-rigidity region is formed by projecting the outer end portion in the width direction of the insertion / extraction port in each post disposed at the both ends. It is in the point formed by bending along the protruding direction of the part.

[Action and effect]
If the high rigidity region is formed by bending the outer end portion in the width direction of the insertion / extraction opening in each post arranged at both ends along the protruding direction of the convex portion as in this configuration, it is also necessary to use a reinforcing member separately. Since the number of parts does not increase, the cost does not increase.

It is a perspective view of the receptacle connector of the present invention. Plan view of receptacle connector of the present invention (a), vertical front view (b) taken along line bb in the plan view (a), and vertical side view (c) taken along line cc in the plan view (a). It is. They are a principal part perspective view (a) when a base part is seen from the upper side, and a principal part perspective view (b) when the base part is seen from the lower side.
