Mold crucible system for connecting tubes and cables and method thereof

1. 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.

2. The system of claim 1 , wherein the mobile piece and the fixed piece are made of sheet metal.

3. The system of claim 1 , wherein the fixed piece has a “U” shape.

4. The system of claim 1 , wherein an the inner contour of the mobile piece reproduces an outer contour of the lower part of the mold-crucible, whereby the outer contour of the lower part of the mold-crucible set acts as a guide during movement of the mobile piece.

5. The system of claim 1 , wherein two magnets are located on the lower part of the mobile piece.

6. The system of claim 5 , wherein both magnets are located on the mobile piece to ensure operational alignment with a contour of the surface of the tube.

7. The system of claim 1 , wherein the mold-crucible set comprises an opening, the opening configured to receive a first bushing, the first bushing having an inner hole adapted to allow insertion of the cable.

8. The system of claim 7 , wherein the inner hole of the first bushing comprises a first inner surface having a conical feature.

9. The system of claim 7 , wherein the inner hole of the first bushing comprises a second inner surface that is cylindrical, the second inner surface configured to have a diameter slightly larger than the diameter of the cable to be welded, thereby allowing the cable to may be introduced into the bushing.

10. The system of one of claim 7 , wherein the inner hole of the first bushing comprises a third inner surface having a conical feature diminishing quickly in diameter, the conical feature configured to stop the cable that is introduced into the bushing.

11. The system of claim 7 , further comprising a complementary bushing adapted for insertion into the first bushing, whereby the complementary bushing is located between the cable and the first bushing, and wherein an exterior surface of the complementary bushing has a conical feature equal to that comprised by the first inner surface of the first bushing.

12. The system of claim 1 , further comprising a lid for the mold-crucible set, the lid comprising a lower part and an upper part, the lower part of the lid comprising a cavity to house a fuse.

13. 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.

14. The process of claim 13 , further comprising the step of introducing a complementary bushing into the first bushing.

15. The process of claim 13 , further comprising the steps of:

inserting and end of a fuse that protrudes from a lid of the mold-crucible set into a connector of a remote ignition device;

placing the lid on the mold-crucible set;

pouring an amount of ignition powder into a chute of the lid;

actuating of the remote ignition device;

removing the lid;

separating a portion of the mold-crucible set from a remainder of the mold-crucible set through an opening of the mobile piece; and

moving the remainder of the mold-crucible set, freeing the welding.
