Patent attributes
An interposer includes a housing having a plurality of through-holes penetrating a first surface and a second surface and a signal contact pair composed of a pair of signal contacts. Each of the signal contacts includes a base portion press-fitted in one of the through-holes, a first contact beam extending from the base portion beyond the first surface, and a second contact beam extending from the base portion beyond the second surface. The pair of signal contacts are positioned adjacently to each other widthwise and are each asymmetrical with respect to a width direction. A first minimum spacing between the first contact beams of the pair of signal contacts is narrower than a second minimum spacing between the base portions of the pair of signal contacts. The signal contact pair has a plane-symmetrical shape with respect to the width direction.
