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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: a waterproof cable with excellent sealing performance comprises an insulating protective sleeve 1, a sun-proof sealing layer 3, a cable lead 6, insulating soft rubber 7 and an insulating inner sleeve 8, wherein the insulating inner sleeve 8 is arranged at the central position inside the insulating protective sleeve 1, and the insulating soft rubber 7 is arranged between the adjacent insulating inner sleeves 8, the cable leads 6 are arranged inside the insulating inner sleeves 8, six cable leads 6 are arranged inside the insulating inner sleeves 8, each cable lead 6 is annularly distributed inside the insulating inner sleeve 8, the insulating protective sleeve 1 is internally provided with a reinforcing structure 5, the reinforcing structure 5 comprises a reinforcing layer 502 arranged inside the insulating protective sleeve 1, reinforcing ribs 501 are uniformly arranged inside the reinforcing layer 502, a plurality of fixed reinforcing blocks 503 are arranged between adjacent reinforcing ribs 501, the reinforcing ribs 501 are arranged in the reinforcing layer 502, and the reinforcing ribs 501 are distributed at equal intervals;

specifically, as shown in fig. 2, when the structure is used, firstly, in the using process, the hardness of the insulating protective sleeve 1 can be increased under the action of the reinforcing ribs 501 and the fixed reinforcing blocks 503, so that the phenomenon that the insulating inner sleeve 8 and the cable conductor 6 are deformed under external impact or extrusion is avoided, the use condition of the waterproof cable is subsequently influenced, the hardness of the waterproof cable is increased, and the service life of the waterproof cable is prolonged;

the first sealing layer 2 is arranged outside the insulating protection sleeve 1, the second sealing layer 4 is arranged outside the first sealing layer 2, when the surface of the waterproof cable is damaged, the second sealing layer 4 has a primary protection effect, and if the second sealing layer 4 is damaged when the external damage force is too large, the second sealing layer 4 has a secondary protection effect through the first sealing layer 2, so that the direct damage under the action of external force is avoided, the sealing performance of the waterproof cable is improved, the surface of the cable is not easy to damage, and the stable use of the cable can be ensured;
