A high-density multipin connector with newly developed miniature compliant press-in pin connection

A high-density multipin connector that utilizes a miniature compliant press-in pin connection applied to the smaller plated-through hole to connect the pin and the backpanel is discussed. The procedure for designing the connection is described. Numerical elastic-plastic deformation analysis is used. A miniature press-in pin has been fabricated using the results of the analysis, and its mechanical performance is examined. Reliability tests confirmed that the contact resistance characteristics are sufficiently stable. The connector is applicable to equipment used in electrical communication systems
