HF sealing strips
View Patent ↗A HF sealing strip ( 1 ) for electromagnetically shielded, insertable electronic modules comprises a core ( 2 ) of an elastically deformable material and a cover ( 3 ) of a flexible, conductive textile fabric. The cross section of the core ( 2 ) corresponds to an isosceles triangle with obtuse angle at the top. One section of the cover ( 3 ) forms a level contact surface ( 4 ), to which adhesive strips ( 7 a; 7 b; 8 ) are attached. In the region of the edges for the contact surface ( 4 ), the cover ( 3 ) of a textile fabric is used to form double-layer flaps ( 6 a, 6 b ) without an elastic core. These flaps ( 6 a, 6 b ) form reinforced, level outside edges of the HF sealing strip ( 1 ), which can thus better withstand shearing forces transverse to the contact surface ( 4 ).
1. A HF sealing strip for insertable, electromagnetically shielded electronic modules, said sealing strip comprising:
a core of a material that is at least in part elastically deformable;
a cover enclosing the core, the cover being made of a flexible, conductive material and adapted to establish an electrical connection between adjacent electronic modules and/or between a chassis for accommodating electronic modules and an electronic module, wherein a section of the cover forms a contact surface and the cover further forms at least one horizontally outward extending double-layer flap in a region of the contact surface on at least a module-insertion side, and wherein the at least one flap is formed by two layers of the cover material fitting against one another.
2. The HF sealing strip according to claim 1 , wherein the two layers of the flap are glued or welded together.
3. The HF sealing strip according to claim 1 , wherein a cross section of the core is in the shape of an isosceles triangle.
4. The HF sealing strip according to claim 3 , wherein an angle between a pair of slanted run-up surfaces opposite the contact surface measures between 80° and 160°.
5. The HF sealing strip according to claim 4 , wherein the angle is approximately 140°.
6. The HF sealing strip according to claim 1 , wherein the core is composed of foamed synthetic material.
7. The HF sealing strip according to claim 1 , wherein the cover is metallized.
8. The HF sealing strip according to claim 1 , further comprising at least one adhesive strip attached to the contact surface.
9. The HF sealing strip according to claim 8 , wherein the adhesive strip is arranged in a region of the at least one flap.
10. The HF sealing strip according to claim 8 , further comprising a conductive adhesive strip arranged in a center of the contact surface between two outer adhesive strips.
11. The HF sealing strip according to claim 1 , wherein a cross section of the core takes the form of a triangle with unequal sides, wherein at least one of the short sides defines a slanted run-up surface and wherein the long side is adjacent to the section of the cover defining the contact surface.
12. The HF sealing strip according to claim 11 , wherein the run-up surface on the module-insertion side and the contact surface jointly form an acute angle of no more than 45°.
13. The HF sealing strip according to claim 12 , wherein the acute angle is less than approximately 30°.
14. The HF sealing strip according to claim 1 , wherein the flexible, conductive material comprises a non-woven material or textile fabric.
15. A HF sealing strip for insertable, electromagnetically shielded electronic modules, said sealing strip comprising:
a core of a material that is at least in part elastically deformable;
a cover enclosing the core, the cover being made of a flexible, conductive material and adapted to establish an electrical connection between adjacent electronic modules and/or between a chassis for accommodating electronic modules and an electronic module, wherein a section of the cover forms a contact surface and the cover further forms at least one double-layer flap in a region of the contact surface on at least a module-insertion side, and wherein the at least one flap is formed by two layers of the cover material fitting against one another, and wherein a cross section of the core takes the form of a triangle with unequal sides, wherein at least one of the short sides defines a slanted run-up surface and wherein the long side is adjacent to the section of the cover defining the contact surface.
16. The HF sealing strip according to claim 15 , wherein the run-up surface on the module-insertion side and the contact surface jointly form an acute angle of no more than 45°.
17. The HF sealing strip according to claim 16 , wherein the acute angle is less than approximately 30°.
18. The HF sealing strip according to claim 15 , wherein the flexible, conductive material comprises a non-woven material or textile fabric.
