Abstract

A ring seal for insertion into the sealing gap between a housing and a housing cover, including a soft elastic sealing body and a flexible conducting strip passing through the sealing body in the transverse direction. The sealing body and the flexible conducting strip are stiffened in the sealing gap by a stiffening element. The stiffening element has an elasticity modulus E and a shear modulus G that are higher than the respective values of the conducting strip. The conducting strip is not substantially larger than the spatial extension of the sealing gap.
