<p>A cable clamping and draining device towards ground of currents induced on the shielding braid of cables for signal transportation passing through a metallic grounded wall of a electromagnetic confinement cabinet containing devices, on which the cables are terminated. The clamping and draining device is set up by at least three conducting plates, of which at least one with dimensions sufficient to overlay completely the light of an opening of said metallic wall and connected mechanically and electrically to it, whereby all plates present the same plurality of holes which can be aligned in a mutually coaxial way among them, and with diameters which are commensurated to the diameter of as many cables which may be introduced separately through the aligned holes of the boards. The clamping and draining device is supplied with forced translation and stopping means of at least one intermediate plate of said plurality of plates, carrying out a clamping action on the cables, bare of the external isolation cladding, separately passing through coinciding holes of the plates, deforming locally the shape and/or rectilinear layout and contemporarily reducing the free opening of holes around the shape of the respective campled cable and the free opening through the holes where no cables are passing through. Holes with a large diameter can be closed by suitable caps or shearing diaphragms when not used. <IMAGE></p> |
