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.
Claims13
A the ring seal for insertion into a sealing gap between a housing and a housing cover, comprising:
- a soft elastic sealing body;
- a flexible conducting strip transversely passing through the sealing body;
- and
- a stiffening element for stiffening the sealing body and the flexible conducting strip within the sealing gap, wherein the stiffening element has an elasticity modulus E and a shear modulus G that are higher than the respective values of the conducting strip, and the conducting strip is not substantially larger than the width of the sealing gap and wherein the stiffening element has two sides and
- wherein the sealing body passes through the stiffening element at at least one point and has partial bodies located on both sides of the stiffening element that are designed in one piece smoothly transitioning into each other.
A the ring seal for insertion into a sealing gap between a housing and a housing cover, comprising:
- a soft elastic sealing body;
- a flexible conducting strip transversely passing through the sealing body;
- and
- a stiffening element for stiffening the sealing body and the flexible conducting strip within the sealing gap, wherein the stiffening element has an elasticity modulus E and a shear modulus G that are higher than the respective values of the conducting strip, and the conducting strip is not substantially larger than the width of the sealing gap,
- wherein the stiffening element laterally overlaps the sealing body to in at lease one direction, and essentially non-deformable spacers are provided in the area laterally adjacent to the sealing body, which limit the deformation of the sealing body to an optimum value when the housing cover and the housing are pressed together.
