Electrical connector and electrical connector pair

The invention relates to an electrical connector and an electrical connector pair. In the plug connector, a locking member of the plug comprises extension bases fixed to a second plug housing and cantilever extensions extending from the respective extension bases in the direction of a plugging operation. The cantilever extensions each have an engaged hole to receive corresponding one of protrusions protruded from a receptacle housing. The cantilever extensions are each resilient enough to bend in the protruding direction of the corresponding protrusion. A releasing member allows the protrusions to relatively move in the directions of plugging and unplugging operations. When the releasing member is slid relative to the second plug housing, the releasing member bends the cantilever extensions in the protruding directions of the respective protrusions and thereby release engagement of the protrusions with the engaged holes. 本发明涉及种电连接器和电连接器对。在插头连接器中，插头侧锁定构件具有相对于第2插头壳体固定的基端部和自基端部向插入方向以悬臂梁状伸出的伸出部。在伸出部形成有供自插座壳体突出的突起
