Abstract

The device comprises a rail (2) inside which two insulating support elements (10) are longitudinally disposed. Said support elements (10) are provided with projecting portions (10a) housing respective wires (11) provided with mutually facing contact surfaces (11a). The latter slightly project with respect to the projecting portions (10a) so that they can come into contact with contact elements (16) extending from a connection shank (13) and substantially flush therewith. The connection shank (13) is part of an adaptor (3) to which a safety low-tension-operated utilization unit can be connected and is engageable with rail (2) through a longitudinal opening (4a).

Claims

1. A device to safely feed low-voltage utilization apparatus with electricity, said device comprising a rail;

an adaptor engageable in a removable manner in said rail and having a connection shank provided with contact elements consisting of laminar bodies extending parallel to the connection shank and substantially flush therewith;

a pair of insulating support elements disposed longitudinally in the rail and having projecting portions; and

at least two facing low-voltage wires housed in the insulating support elements between the projecting portions and exhibiting contact surfaces engageable with the contact elements of the connection shank and projecting inwardly in the rail beyond the projecting portions of the insulating support elements.
