Abstract
A new anchoring mechanism for the mold-crucible set to the tube, to which the cable is to be welded is described, and the inclusion and use of some bushings which are inserted between the cable and the mold.
Claims15
A system for connecting cables and tubes, the system comprising:
- a mold-crucible set adapted to provide an aluminothermic reaction therein to generate a connection of a cable to a tube,
- an anchoring mechanism adapted for its attachment to a surface of a tube, the anchoring mechanism comprising:
- a fixed piece anchored to the mold-crucible set;
- a mobile piece located on a lower part of the mold-crucible set;
- at least one magnet located on a lower part of the mobile piece, the at least one magnet adapted to create a magnetic field to generate a connection force between the surface of the tube and the anchoring mechanism;
- and
- at least one traction spring extending that extends between the fixed piece and the mobile piece.

A process for connecting cables and tubes, the process comprising the steps of:
- placing an anchoring mechanism of a system for connecting cables and tubes near a tube, wherein the said system comprises:
- a mold-crucible set adapted to provide an aluminothermic reaction therein to generate a connection of a cable to a tube,
- an anchoring mechanism adapted for its attachment to a surface of a tube, the anchoring mechanism comprising:
- a fixed piece anchored to the mold-crucible set;
- a mobile piece located on a lower part of the mold-crucible set;
- at least one magnet located on a lower part of the mobile piece, the at least one magnet adapted to create a magnetic field to generate a connection force between the surface of the tube and the anchoring mechanism;
- and
- at least one traction spring extending that extends between the fixed piece and the mobile piece;
- exerting a force over the mobile piece to bring the mobile piece near the surface of the tube, thereby tractioning the at least one traction spring;
- contacting the at least one magnet with the surface of the tube;
- introducing an end of the cable to be connected by welding into an opening of the mold-crucible set, the opening configured to receive a first bushing, the first bushing adapted to allow the insertion of the cable;
- pouring aluminothermic powder and ignition powder into the mold-crucible set;
- and
- welding the cable to the tube upon ignition of the powders.
