Abstract
Abstract A device for contacting a substrate, preferably an electrical conductor, with spring parts that are in contact with the substrate at a plurality of points. Substrates of different diameters can be contacted without problem and for electrical conductors a high HF-impermeability is guaranteed. The device comprises at least one helical spring (5) arranged substantially annularly in a housing (1), with the helical windings (9) of the spring inclined at an angle α to the radial plane (10) perpendicular to the contact axis (11) When different sized substrates are inserted the windings turn, changing the angle α. This requires little force. Also the spacing of adjacent helical windings is maintained so that for electrical conductor substrates the same high HF impermeability is guaranteed for all conductor diameters.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
71 words
A device for contacting an elongate substrate with spring parts that are in contact with the substrate at a plurality of points, comprising at least one helical spring (5) arranged substantially annularly in a housing (1), the spring having helical windings (9) which are set at an angle α to the radial plane (10) perpendicular to the substrate middle axis (11), which can notionally be assigned to each helical winding (9).
Claim 2
Independent Claim
71 words
A device for contacting an elongate substrate with spring parts that are in contact with the substrate at a plurality of points, comprising at least one helical spring (5) arranged substantially annularly in a housing (1), the spring having helical windings (9) which are set at an angle α to the radial plane (10) perpendicular to the substrate middle axis (11), which can notionally be assigned to each helical winding (9).
Claim 3
Independent Claim
55 words
A device for contacting an elongate substrate with helical springs parts that are in contact with the substrate at a plurality of points, wherein in the position of use, the helical spring (5ʹ) extends substantially angularly, eliptically, polygonally or in any shape other than an annular shape for the purpose of contacting correspondingly shaped substrates.
Claim 4
Independent Claim
55 words
A device for contacting an elongate substrate with helical springs parts that are in contact with the substrate at a plurality of points, wherein in the position of use, the helical spring (5ʹ) extends substantially angularly, eliptically, polygonally or in any shape other than an annular shape for the purpose of contacting correspondingly shaped substrates.
Claim 5
Dependent Claim
40 words
A device according to claim 2, wherein the spring has helical windings (9) which are set at an angle α to the radial plane (10) perpendicular to the substrate middle axis (11) which can notionally be assigned to each winding.
Claim 6
Independent Claim
19 words
A device according to any preceding claim for contacting an electrical conductor, wherein the spring comprises electrically conductive material.
Claim 7
Independent Claim
20 words
A device according to any preceding claim wherein the helical spring (5) is accommodated in an electrically conductive housing (1).
Claim 8
Independent Claim
38 words
A device according to any one of the preceding claims, wherein the helical spring (5ʺ) surrounds a plurality of cable inlet sockets at least in regions for the purpose of contacting the respective outer conductors of coaxial cables.
