Circuit board electrical connector

摘要

A circuit board electrical connector which includes a first connector (10) connectable to a first external member (Q) and a second connector (30) connectable to the first connector at one end and a second external member at the other end opposite to the one end. The first connector includes an insulation block (11) with a connection recess (12) having an opening on a front side thereof; a plurality of first contact elements (20, 21) disposed within the insulation block such that contact portions are exposed in the connection recess. The second connector includes a contact support (38); a connection section (31) connected to the contact support at one end and to be inserted into the connection recess on the other end opposite to the one end; a plurality of second contact elements (33-36) having contact portions (33A-36A) disposed on the connection section for spring contact with the first contact elements and connection portions (33B-36B) extending through the contact support for connection with the second external member; an arrangement pitch of the contact portions of the second contact elements being different from that of the connection portions of the second contact elements.
