Claim:
A connector assembly comprising: a header: said header having a header body made of an insulating material and a header contact member made of a conductive material and held by said header body; a socket: said socket having a socket body made of an insulating material and having a connective concave portion into which said header body is inserted and a socket contact member made of a conductive material and held by said socket body so that it is in contact with said header contact member inside said connective concave portion when said header body is inserted into said connective concave portion; wherein said socket contact member has a first contact piece and a second contact piece which are provided in a spaced relation to each other in a direction perpendicular to an insertion direction of said header so that they each can make contact with said header contact member, said header contact member having a first contact piece configured to make contact with said first contact piece of said socket contact member and a second contact piece configured to make contact with said second contact piece of said socket contact member, one first contact piece of said socket contact member and said header contact member having a first protrusion elastically projecting in a direction perpendicular to the insertion direction of said header and the other first contact piece of said socket contact member and said header contact member having a second protrusion configured to climb over said first protrusion when said header body is inserted into said connective concave portion, said first protrusion and said second protrusion constituting a lock mechanism by engaging with each other when said header body is inserted into said connective concave portion, one second contact piece of said socket contact member and said header contact member having a concave portion in a surface which is for making contact with the other second contact piece, a gap being formed between said the other second contact piece and an inner surface of said concave portion of said one second contact piece when said one second contact piece makes contact with said the other second contact piece.
