Abstract
Abstract In a housing-like structure which contains electrical apparatuses, a resilient, profile-like sealing element (3) and a shielding element (6) are combined to form a flexible profile (5) in order to seal the adjacent surfaces of components (1, 4) against foreign substances and at the same time to prevent high-frequency or electromagnetic fields and radiation from passing in or out. The sealing element (3) can contain a strip-like, resilient core (7) which is provided with an envelope (8) as thin as a film and consisting of electrically conductive material.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
A sealing device for sealing two components of a housing means for electrical apparatus to effectively prevent entry of gas, air, and moisture and for shielding against electromagnetic fields comprising: a first outer, elongated member made of a resilient material said first member including upper and lower surfaces; and a second inner member having a band-like core made of a resilient material and a thin-film envelope of an electrically conductive material surrounding said core, said second member being inserted into said first member, said second member having top and bottom ends projecting beyond said upper and lower surfaces of said first member.
Claim 2
Dependent Claim
102 words
A sealing device for sealing two components of a housing means for electrical apparatus to effectively prevent entry of gas, air, and moisture and for shielding against electromagnetic fields comprising: a first outer, elongated member made of a resilient material said first member including upper and lower surfaces; and a second inner member having a band-like core made of a resilient material and a thin-film envelope of an electrically conductive material surrounding said core, said second member being inserted into said first member, said second member having top and bottom ends projecting beyond said upper and lower surfaces of said first member.
Claim 3
Dependent Claim
20 words
A sealing device as claimed in claim 1, wherein said core and said envelope are adhesively bonded to one another.
Claim 4
Dependent Claim
30 words
A sealing device as claimed in claim 2, wherein said outer member includes two profile parts which are located on two opposite sides of said envelope of said inner member.
Claim 5
Dependent Claim
27 words
A sealing device as claimed in claim 3, wherein said core and said outer member are made of a flexible, resilient or a tough, resilient foamed plastic.
Claim 6
Dependent Claim
26 words
A sealing device as claimed in claim 4, wherein a plurality of inner members are arranged side by side, a distance apart, in said outer member.
Claim 7
Dependent Claim
25 words
A sealing device as claimed in claim 5, wherein the inner surface of said outer member and outer surface of said envelope are frictionally bonded.
Claim 8
Dependent Claim
22 words
A sealing device as claimed in claim 6, wherein the modulus of elasticity of said outer member and said core are identical.
Claim 9
Dependent Claim
22 words
A sealing device as claimed in claim 6, wherein the modulus of elasticity of said outer member and said core are different.
