In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a reel cable collecting box, includes the box, the mounting hole has been seted up to box one side, the mounting hole is used for acceping three-core cable, the one end that three-core cable was located the box includes A looks terminal, B looks terminal and C looks terminal, the box is inside to be followed three core cable direction is equipped with interval arrangement in proper order and gets electricity ring and three looks electricity ring through the fixed ground wire of support insulator, the ground wire is got electricity ring centre bore and is fixed with the ground wire insulating disc, the ground wire insulating disc is used for fixing three core cable inlet wire, it is fixed with looks insulating disc to get the downthehole correspondence of electricity ring centre mutually, respectively set up three equidistant through-hole on ground wire insulating disc and the three looks insulating disc, be fixed with respectively in the through-hole A looks terminal, B looks terminal and C looks terminal.
Preferably, the ground wire insulating disc and the phase insulating disc are both made of epoxy resin.
Preferably, the outer layer of the A-phase terminal, the outer layer of the B-phase terminal and the outer layer of the C-phase terminal are respectively sleeved with a PVC pipe, an air gap between each PVC pipe and each phase terminal forms a glue filling area, sealant is filled in the glue filling areas, the PVC pipes and the sealant can play a role in strengthening and fixing, the sufficient insulation distance is ensured, and the sufficient distance between each phase terminal and the supporting insulator is ensured, so that the discharging phenomenon is avoided.
Preferably, the phase a terminal, the phase B terminal and the phase C terminal are respectively and correspondingly abutted against the phase taking electrical ring through each phase connecting line, and the directions of the phase connecting lines are different by 120 °.
As described above, the utility model discloses drum reel cable collecting box is equipped with ground wire insulating disc and three looks insulating disc, will the A looks terminal, B looks terminal and the C looks terminal of three-core cable are fixed and keep apart mutually to guarantee that the insulating distance between equipment cable receiving and cable laying in-process each looks terminal does not change, solved in the collecting box because of the insulating distance changes the problem that leads to alternate air gap to puncture.
