A method for use in connecting electric cables (3) in e. g. cable terminal boxes (5), of providing a sealed cable lead-through into the box (5). The purpose of the invention is to provide, rapidly and by simple means, an efficient seal of cable lead-through arrangements of the type defined above. This is achieved in accordance with the invention in that an attachment frame (1) is applied around an opening formed in the box (5), which attachment frame (1) is provided with flange portions (6, 8) and with a top piece (9). Onto each cable to be connected to the box (5) is wound a vulcanizing tape (16) of a kind known per se. The electric cables (3), thus provided with tape, are then inserted through the opening (2) and positioned adjacent and on top of one another with the layers of vulcanizing tape (16) in connecting relationship. Gauge blocks (17) of rubber, is needed after having been cut to fitting size, are positioned on either side of the bundle of cables thus formed, between said bundle and the adjacent lateral flange (8). At least one elongated packing piece (18) of rubber is applied on top of the bundle of cables and the top piece (9) is mounted above the packing piece so as to exert a pressure thereon. |
