[0026] Please refer to Figure 1 and Figure 2 A cold shrink forming device of a cable connection terminal, comprising: a forming die 1, the inner wall of the forming die 1 is provided with a forming die groove 2, the inner wall of the forming die 1 is provided with a heating and cooling device 3, the inner wall of the forming die 1 is provided with a cloth bag 4, the cloth bag 4 is used to fix the elastic insulation sleeve, then the heating and cooling device 3 heats the insulation sleeve, then the cable is moved to the outside of the insulation sleeve through the forming die groove 2, then the heating and cooling device 3 is cooled to make the insulation sleeve heat expansion and cold shrink to be adsorbed on the outside of the cable.

[0027] Please refer to Figure 2 and Figure 3The outer wall of the forming mold 1 is provided with a heat dissipation mechanism, which is used to strengthen the heat dissipation efficiency in the forming mold 1, and quickly dissipate the heat of the inner wall, so that the elastic insulation sleeve is quickly adsorbed on the outside of the cable. The heat dissipation mechanism comprises a mounting platform 5 which is arranged on the outer wall of the forming mold 1. The top of the mounting platform 5 is provided with a maintenance electric pole 6. The output end of the maintenance electric pole 6 is provided with a heat dissipation shell 7. The inner wall of the heat dissipation shell 7 is provided with a breathable hole 8. The inner wall of the heat dissipation shell 7 is provided with a heat dissipation fan 9. The inner wall of the heat dissipation shell 7 is provided with a first magnet 10. The outer wall of the first magnet 10 is provided with a second magnet 11. The outer wall of the second magnet 11 is provided with a protective net 12. The inner wall of the forming mold 1 is provided with a heat dissipation groove 13. Since a large amount of heat is stored in the insulation sleeve after heating, it takes a long time to cool down and shrink the insulation sleeve. Therefore, it is necessary to improve the efficiency of the cooling and shrinking process. The heat dissipation fan 9 works to dissipate the heat in the heat dissipation groove 13, and the heating and cooling device 3 works to cool down. In this way, the heat in the insulation sleeve is quickly dissipated, and the insulation sleeve is quickly adsorbed on the outside of the cable. When the heat dissipation shell 7 needs to be maintained, the maintenance electric pole 6 drives the heat dissipation shell 7 to move. The protective net 12 is pulled to remove the second magnet 11 from the first magnet 10, and the heat dissipation fan 9 is maintained.

[0028] Please refer to Figure 1 and Figure 4 The outer wall of the forming mold 1 is provided with an auxiliary mechanism, which is used to facilitate the heat insulation or cold insulation of the forming mold 1, and facilitate the disassembly of the forming mold 1. The auxiliary mechanism comprises a covering plate 14 which is arranged on the outer wall of the forming mold 1. The outer wall of the covering plate 14 is provided with an insulation layer 15.

The outer wall of the first magic tape 19 is provided with a second magic tape 20. The outer wall of the second magic tape 20 is provided with an anti-skid layer 21. When the insulation sleeve is heated or cooled, the heat or cold air will affect the forming mold 1, and the workers will be affected by the hot air or cold air when disassembling the forming mold 1. Therefore, it is necessary to improve it. First, place the covering plate 14 on the outer wall of the forming mold 1, then fix the threaded rod 17 in the threaded groove 16, then use the insulation layer 15 to insulate the hot air or cold air, and then use the anti-skid layer 21 to adsorb the first magic tape 19 on the first magic tape 19, and then use the disassembly handle 18 to disassemble the forming mold 1.

[0029] The working principle is that the elastic insulation sleeve is fixed by the cloth bag 4, then the heating and cooling device 3 heats the insulation sleeve, then the cable is moved to the outside of the insulation sleeve through the forming die groove 2, then the heating and cooling device 3 cools to make the insulation sleeve heat expansion and cold shrink adsorbed on the outside of the cable, since a large amount of heat is stored in the insulation sleeve after heating, so that a long time is needed to cool the insulation sleeve to cold shrink, therefore, improvement is needed to improve the efficiency of cold shrink, the heat dissipation fan 9 works to dissipate the heat in the heat dissipation groove 13, and the heating and cooling device 3 cools, so that the heat in the interior is quickly dissipated, so that the insulation sleeve quickly adsorbs on the outside of the cable, and when the inside of the heat dissipation shell 7 needs to be overhauled, the overhaul rod 6 drives the heat dissipation shell 7 to move, pulls the protective net 12 to make the second magnet 11 removed from the first magnet 10, and then the heat dissipation fan 9 is overhauled, when the insulation sleeve is heated or cooled, the heat or cold air will affect the forming die 1, so that the workers will be affected by the hot air or cold air when disassembling the forming die 1, therefore, improvement is needed, first, the cover plate 14 is placed on the outer wall of the forming die 1, then the threaded rod 17 is fixed into the threaded groove 16, then the heat or cold air is isolated by the isolation layer 15, and the anti-skid layer 21 is adsorbed on the first magic tape 19 by the second magic tape 20, then the forming die 1 is disassembled by the disassembly handle 18.

[0030] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments but can be implemented in other embodiments without departing from the spirit or essential characteristics of the application. Thus, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
