PURPOSE: To provide a printed circuit board contact system whose structure is simple and not bulky, which can be economically produced, retains desired impedance level, and is optimum to be used in a high speed digital printed circuit board. CONSTITUTION: This printed circuit board contact system is applied to a high speed digital field comprising a socket having slots made of a beryllium copper or other conductive spring materials and tapered as a whole. The socket 10 has a corrugated shape forming a series of outside contact parts and inside contact parts made gradually smaller and the inside parts and the outside part are alternately arranged. When a pin 24 having a proper size is inserted into the socket 1, at least one of the inside contact part is widened in the radius direction and the neighboring outside contact part is pushed to a sleeve lining of a hole of a printed circuit board and into which the socket 10 is inserted, so that the pin and the socket are mutually interlocked. At least a part of the socket is put constantly under a proper load by widening the socket 10 and consequently proper holding force and physical and electric contact can be retained for a long duration. |
