Abstract: An electrical connector includes a housing having a slot formed therein. The electrical connector further includes a plurality of conductive contact bands disposed within the slot. Each of the contact bands has a surface with a roughness defined by a plurality of microscopic irregularities. Each of the contact bands additionally has a plurality of projections, each of which projects above the surface of the contact band by a distance equal to a value between about 0.1% and 99% of a width of the contact band. The projections of each contact band electrically engage, at a plurality of different locations, with a conductive member insertable into the slot.
