RECEPTACLE CONNECTOR

A receptacle connector (20) comprises: a housing (200) in which is formed a recess (203) that accommodates a plug connector (30) on the side opposite a substrate mounting surface; a required number of contacts (220) that are arranged between both ends of the housing (200); and a reinforcement fitting (230) that is provided on each end of the housing (200). The reinforcement fitting (230) includes: a cantilever elastic piece (235) that extends along the arrangement pitch direction of the contacts (220); and a contact piece(236) that extends from a free end edge of the cantilever elastic piece (235) and that contacts the plug connector (30) when the receptacle connector (20) engages the plug connector (30). 本发明的插座连接器(20)具备：壳体(200)，其在与基板安装面相反的一侧形成有收容插头连接器(30)的凹部(203)；所需数量的触头(220)，其排列在壳体(200)的两端部之间；以及加强件(230)，其分别设置于壳体(200)的两端部。加强件(230)具有：悬臂弹性片(235)，其沿着触头(220)的排列间距方向延伸；和接触片(236)，其从该悬臂弹性片(235)的自由端侧端部伸出，并在插座连接器(20)与插头连接器(30)的嵌合时与该插头连接器(30)接触。
