Patent ID: 8025517

Claim:
A connector interface having an insertion axis and two opposing mating faces, said connector interface comprising: A. a mating protrusion having one of said two opposing mating faces and a mating receptacle having one other of said two opposing mating faces; B. at least one flexible rib being part of and extending above at least one of said two opposing mating faces, wherein said at least one flexible rib is propagating substantially circumferentially continuous around said at least one of said two opposing mating faces; B. a saw tooth cross section of said at least one flexible rib that is including a steep flank and a shallow flank; and wherein 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 wherein a flank angle difference between said first flank angle and said second flank angle is such that during an interface connecting compression said shallow flank is in substantial pressure contact with one other of said two opposing mating faces and said steep flank is substantially free of contact with said one other of said two opposing mating faces.
