The utility model adopts the technical proposal that:

the utility model provides a high-efficient waterproof splice box, includes terminal seat and the separation blade of barrel, extra large cable head anchor clamps, barrel both sides, both sides extra large cable head anchor clamps are fixed in both sides terminal seat respectively, set up the support between the extra large cable head anchor clamps of both sides, are equipped with the fine box of dish on the support, the barrel overlaps on two extra large cable head anchor clamps, and terminal seat embedding barrel both sides, and the terminal seat outside is fixed with the separation blade in the barrel side.

Furthermore, the cylinder body adopts a large-small head structure, the diameter of the left terminal seat is slightly larger than that of the right terminal seat, and the assembly is more convenient.

Furthermore, the submarine cable head clamp and the terminal seat are locked by a locking nut, and a cover plate is arranged at the end part of the submarine cable head clamp outside the cylinder.

Furthermore, the two sides of the support are fixed in the conical plugs in the submarine cable head clamp, the support is made of high-strength steel, and the conical plugs are hermetically fixed in the submarine cable head clamp through screw caps.

Furthermore, an O-shaped ring I is arranged between the cylinder and the terminal seat, and an O-shaped ring II is arranged between the submarine cable head clamp and the terminal seat, so that the device is stronger in sealing performance.

Furthermore, the taper plug is made of fluororubber, and the taper is 7-9 degrees.

The utility model has the advantages that:

1. the utility model adopts the big-end and small-end structure, when assembling, the submarine cable head clamp connecting structure can be sleeved from one side, and the installation is more convenient;

2. the two sides of the device cylinder body of the utility model are provided with the separation blades, which can improve the stability of the device and prevent the rotation of the submarine cable head clamp;
