Patent ID: 8147264

Claim:
A connector, comprising: a mating protrusion having an insertion axis and a mating face; and at least one flexible rib being part of and extending above the mating face, wherein the at least one flexible rib propagates substantially continuously around a circumference of the mating face, the at least one flexible rib having a saw-tooth cross section including a steep flank and a shallow flank, wherein the shallow flank comprises a first flank angle with respect to the insertion axis and the steep flank comprises a second flank angle with respect to the insertion axis, wherein a flank angle difference between the first flank angle and the second flank angle is configured such that when the connector is coupled to a complementary connector, the shallow flank is in substantial pressure contact with a mating face of the complementary connector, and the steep flank is substantially free of contact with the mating face of the complementary connector, and wherein the steep flank joins the shallow flank at a sharp circumferential edge.
