Abstract

Abstract A shielding string comprising at least at its surface a wire testure is arranged in a groove between the surfaces of two juxtaposed parts of a housing for electronic apparatus in order to attain a sealing for high frequency. This shielding string is cut accurately to size from a longer piece, while at the cutting areas loose wire parts of the texture can be formed, which, after the shielding string has been arranged, can fall into the housing containing the electronic circuit and can give rise there to short circuits. In order to avoid this, the ends of the shielding string are inserted into blind holes, which are provided in the groove. The groove can be widened in the area of the blind holes so that the two ends of the shielding string extend in parallel over a short distance. In order that the ends can be more readily fixed and the wire ends are kept from falling out, the blind holes can be provided with an adhesive.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 67 words
A shielding arrangement comprising a stranded elastic shielding body having a substantially constant cross-section, which body is arranged between two housing parts in a groove provided in the surface of one of the housing parts, characterized in that the two ends of the shielding body are each inserted into a blind hole directed perpendicularly to the surface of the one housing part and located in the groove.
Claim 2
Dependent Claim 67 words
A shielding arrangement comprising a stranded elastic shielding body having a substantially constant cross-section, which body is arranged between two housing parts in a groove provided in the surface of one of the housing parts, characterized in that the two ends of the shielding body are each inserted into a blind hole directed perpendicularly to the surface of the one housing part and located in the groove.
Claim 3
Dependent Claim 32 words
A shielding arrangement as claimed in claim 1, wherein said groove is in the form of a closed ring, and said blind holes are arranged in the groove immediately behind each other.
Claim 4
Dependent Claim 69 words
A shielding arrangement as claimed in claim 1, wherein said groove is in the form of a closed ring that is widened in a region to approximately double its cross-section and one of said blind holes is formed at each end of the region, and the shielding body is arranged in the groove in such a manner that the two ends lie in the region one beside the other.
Claim 5
Dependent Claim 34 words
A shielding arrangement as claimed in any one of claims 1 to 3, characterized in that the blind holes are provided with an adhesive into which the ends of the shielding body are inserted.
