6. Cable feed-through as defined in claim 5 , wherein the bristle element is secured as a result of its position between the support on the housing side and the fixing device.
7. Cable feed-through as defined in claim 6 , wherein the fixing device acts on the bristle element with an elastic force in a direction of a contact surface on a housing side.
8. Cable feed-through as defined in claim 7 , wherein a fixing in position of the cable in the fixing device generates a force on the fixing device acting on the bristle element in a direction of a contact surface on a housing side.
9. Cable feed-through as defined in claim 2 , wherein the support has a contact surface on a housing side facing the outer opening.
10. Cable feed-through as defined in claim 1 , wherein the bristle element is in electrically conducting contact with an inner surface of the housing.
11. Cable feed-through as defined in claim 10 , wherein the bristle element abuts on the inner surface of the housing by means of an element spreading outwards as a result of elastic tensioning.
12. Cable feed-through as defined in claim 1 , wherein the bristle element is fixed in the housing in a force locking manner.
13. Cable feed-through as defined in claim 12 , wherein the bristle element abuts on an inner surface of the housing in a force locking manner as a result of an element spreading elastically outwards.
14. Cable feed-through as defined in claim 1 , wherein the fixing device comprises an insert insertable into the housing, the cable being fixable in said insert.
15. Cable feed-through as defined in claim 14 , wherein the insert has elastic areas adapted to be acted upon by a cap nut.
16. Cable feed-through as defined in claim 15 , wherein the cap nut acts on the insert in a direction of a contact surface on a housing side.
17. Cable feed-through as defined in claim 16 , wherein the insert acts on the bristle element in the direction of the contact surface on the housing side.
18. Cable feed-through as defined in claim 1 , wherein the bristle element has at least one circle of bristles extending at least partially around a central axis of a cable feed-through channel.
19. Cable feed-through as defined in claim 18 , wherein the bristle element has two circles of bristles arranged so as to be offset relative to one another in the direction of the central axis.
20. Cable feed-through as defined in claim 1 , wherein the bristles extend transversely to a central axis of the cable feed-through channel in a state not making contact with the cable shield.
21. Cable feed-through as defined in claim 1 , wherein the bristles extend approximately radially to a central axis in a state not making contact with the cable shield.
22. Cable feed-through as defined in claim 1 , wherein the bristles extend from the bristle support as far as a central opening.
23. Cable feed-through as defined in claim 1 , wherein the bristles have an approximately round or oval cross section.
24. Cable feed-through as defined in claim 1 , wherein the bristles have a cross section with a flat side.
25. Cable feed-through as defined in claim 1 , wherein the bristles have a cross sectional surface area with a maximum diameter smaller than 1 mm.
26. Cable feed-through, comprising:
a housing fixable to an appliance,
a fixing device for a cable held on the housing, and
a shield contact element held on the housing,
the shield contact element comprising a bristle element making contact with a cable shield with elastic and electrically conductive bristles,
the bristle element having a bristle support designed in a C shape or like a ring, the bristles being anchored in said support by means of a U-shaped bent portion,
the bristles being designed as double bristles, each bristle extending from a respective arm of the U-shaped bent portion.
27. Cable feed-through as defined in claim 26 , wherein the bristle support forms an outwardly spreading element.
28. Cable feed-through as defined in claim 26 , wherein the bristle support has an inner member, the U-shaped bent portion engaging around said inner member.
29. Cable feed-through as defined in claim 28 , wherein the U-shaped bent portion engages around the inner member from a side facing away from a central axis.
30. Cable feed-through comprising:
a housing fixable to an appliance,
a fixing device for a cable held on the housing, and
a shield contact element held on the housing,
the shield contact element comprising a bristle element making contact with a cable shield with elastic and electrically conductive bristles,
the bristle element having a bristle support,
the bristle support being designed as an annular member provided with a radial slot and forming an outwardly spreading element, and the bristles being anchored in the bristle support by means of a U-shaped bent portion.
31. Cable feed-through as defined in claim 30 , wherein the bristles are designed as double bristles and each bristle extends from a respective arm of the U-shaped bent portion.
32. Cable feed-through comprising:
a housing fixable to an appliance,
a fixing device for a cable held on the housing, and
a shield contact element held on the housing,
the shield contact element comprising a bristle element making contact with a cable shield with elastic and electrically conductive bristles,
