<p>The invention relates to a new type of power cord, which has an accessible part (1) and a wrapping mechanism housing (2) in which a winding cylinder (3) is arranged. Around that an insulated wire with a ground conduit (4) is wound either manually by a winding lever (6) or automatically by an electric motor (7). The one end of the wire is coupled, through a conical mouth (12) and a passage tube (13), to an insulated wire of phase and neutral conduits (18) at the connection cone (14). The coupling is effected by a male (31) and a female Velcro (32), either by a connection component (33). The connected pair of wires (19) ends to a socket terminal (21) while the other two ends of the insulated wires end to a plug (23). The power cord may have a safety relay (22), an automatic fuse (24), a thermal fuse (25) and measuring instruments.</p> |
