Definitions

  • the present invention relates to a telecom ⁇ munications device comprising means, such as connector strips or the like, for making a cross-connection/con ⁇ nection of telecommunications cables.
  • EMC electromagnetic radiation
  • ESD electrostatic discharges
  • a separate connection/cross-connection space for cables comprising an interfer- ence-shielded enclosure containing substantially all cross-connection/connection means of the equipment, and that the cables to be lead into the enclosure are grounded to said enclosure.
  • the invention is based on the idea of a separ- ate connection and cross-connection space for the cables of telecommunications equipment, which space is shielded against electromagnetic radiation and electro ⁇ static discharges with a mechanical enclosure envelop ⁇ ing the space and being conductive and sufficiently tight (Faraday shield).
  • the mechanical shielding en ⁇ closure may be accomplished by means of cassettes or racks according to standard that are conductive or coated with a conductive material, for example metal cassettes or metal racks.
  • the cables in turn may be grounded galvanically by means of conductive inlets or capacitively by means of a capacitor.
  • the device shown in the drawing includes twin cables 1 and coaxial cables 2.
  • the device For the cross-connec ⁇ tion/connection of the twin cables 1, the device com ⁇ prises connector strips 3 fitted to at least one support 4 for several connector strips 3, and the support 4 in turn is secured to a metal enclosure 5.
  • the device comprises corresponding connector strips 6 for the cross-connection/connection of the coaxial cables 2, said strips also being secured to the enclos ⁇ ure 5 via at least one support 7.
  • the enclosure 5 is further closed with a metal lid 8, and thus all cross- connections/connections with their cross-connection/ connection means 3, 4, 6 and 7 are shut within the interference-shielded closed jacket formed by enclosure 5 and lid 8. Further, the interference-shielded sheaths of cables 1 and 2 to be lead into the jacket are grounded to this interference-shielded jacket, in this exemplary case by means of galvanically conductive inlets 9 fitted in the enclosure 5.
