Patent ID: 7766682

Claim:
A connecter having an insertion axis and a mating face, wherein: a. said connector comprises a housing, a flexible rib extending above said mating face of said housing and wherein said flexible rib is propagating along said mating face in a substantial angle with respect to said insertion axis; b. said flexible rib comprises a saw tooth cross section including a steep flank and a shallow flank such that during substantially radial compression induced by an opposing mating face said flexible rib provides an asymmetric friction resistance against said opposing mating face along said insertion axis; c. a substantial portion of a radial contact pressure area is within a radial base area of said flexible rib during said substantial radial compression; d. said shallow flank comprises a first flank angle with respect to said insertion axis and said steep flank comprises a second flank angle with respect to said insertion axis; and e. a flank angle difference between said first flank angle and said second flank angle is such that during said substantially radial compression substantially only said shallow flank is in pressure contact with an opposite mating face providing said radial compression.
