Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Please refer to fig. 1 and fig. 2, which are schematic structural diagrams of the cable intermediate joint 1 with the waterproof sheath and the cable 6 installed therein according to the present invention.

The cable intermediate joint 1 with the waterproof sheath comprises an intermediate joint 2, an installation cylinder 3, a sheath 4 and an air tap 5. The structure of the intermediate joint 2 is identical to that of the existing product, and therefore, the description is omitted. The mounting cylinder 3 is a plastic cylinder which is split in half along the longitudinal direction, the outer wall of the mounting cylinder is covered with a coating which reduces friction, and the edge of the right end of the mounting cylinder is outwards expanded to form a handle 31 with a flange-shaped structure.

The sheath 4 comprises a waterproof jacket 41 and two heat-shrinkable rings 42. The waterproof jacket 41 is a cylindrical elastic waterproof rubber jacket, and the heat-shrinkable ring 42 is a heat-shrinkable rubber ring. The waterproof cover 41 is sleeved on the installation barrel 3 in a stretched state, that is, the waterproof cover 41 is contracted after the installation barrel 3 is removed. The outer wall of the right end of the waterproof sleeve 41 is sleeved with one heat-shrinkable ring 42 along the edge, and the position of the outer wall of the left end, which is 2cm away from the edge, is sleeved with the other heat-shrinkable ring 42.

The length of the part of the waterproof jacket 41 between the two heat-shrinkable rings 42 is greater than the length of the intermediate joint 2 to ensure sufficient coverage. The length of the installation cylinder 3 is longer than that of the whole waterproof jacket 41 so as to ensure full bearing.

The air tap 5 comprises an air extraction hard tube 51, an air extraction hose 52 and a butt joint 53 which are connected in sequence. Wherein the air extraction hard tube 51 is fixed on the inner wall of the left end of the waterproof jacket 41 by gluing and is clamped between the waterproof jacket 41 and the installation cylinder 3 under the action of the elasticity. And the air exhaust hard pipe 51 does not contact the position of the heat shrinkage ring 42 at the left end.

Please refer to fig. 3 to 5, which are schematic structural diagrams of the mounting tube 3, the mounting step, and the air faucet 5 after removal.

The installation process is as follows: the installation cylinder 3 is moved to any cable 6, and then the intermediate connector 2 is used for butting two cables 6 according to a conventional method. After the cables 6 are butted, the installation barrel 3 is transferred back to the outside of the intermediate joint 2.

The installation cylinder 3 is drawn out through the handle 31, and after the installation cylinder 3 is drawn out, the installation cylinder 3 can be smoothly removed from the cable 6 because the installation cylinder is split in half. The waterproof case 41 is contracted by its own elastic force to be in a state shown in fig. 3.

And heating the heat-shrinkable ring 42 at the right end to shrink the heat-shrinkable ring and lock the right end of the waterproof sleeve 41 on the cable 6 at the right end. And then, any equipment with an air suction function, such as an air pump, a handheld air bag exhaust tool and the like, is butted with the butt joint nozzle 53, so that the air in the waterproof jacket 41 is exhausted, and the waterproof jacket 41 is tightly jointed with the intermediate joint 2. Finally, the heat-shrinkable ring 42 at the left end is heated to shrink and lock the left end of the waterproof jacket 41 on the cable 6 at the right end, so as to form the state shown in fig. 4.

Under the condition of no proper air suction equipment, the butt joint nozzle 53 can be directly sucked by a manual nozzle, and the air in the waterproof sleeve 41 can be evacuated. The purpose of emptying is only to make the waterproof jacket 41 tightly attached to the intermediate joint 2, so as to avoid abrasion of the waterproof jacket 41 caused by relative sliding between the waterproof jacket 41 and the intermediate joint, and no special requirement is imposed on the vacuum degree.

Finally, cutting off the waterproof jacket 41 connected with the air extraction hard tube 51 by using a cutter or directly tearing off the waterproof jacket to form a state shown in figure 5, thereby completing the whole installation operation.

The above-mentioned only be the embodiment of the present invention, not consequently the restriction of the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transform made of the content of the specification of the present invention, or directly or indirectly use in other relevant technical fields, all including in the same way the patent protection scope of the present invention.
