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 of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a waterproof communication line comprises a cable main body 1 and a wire protecting sleeve 2, wherein a core wire of the cable main body 1 is welded with a rubber core inside the wire protecting sleeve 2 corresponding to a pin position, a heat-shrinkable sleeve is baked at a welding spot for protection and insulation, and a sealing assembly for performing waterproof sealing treatment on a connecting position is further arranged in the wire protecting sleeve 2;

the sealing component comprises a sealing ring 5, a pressing plate 4 and a threaded ring 3 which is screwed on the outer surface of the wire protecting sleeve 2 through threads, the pressing plate 4 is provided with two pressing plates 4, the cross sections of the two pressing plates 4 are of arc structures, an annular groove is formed in the sealing ring 5, one end of the pressing plate 4 is inserted into the annular groove, the sealing ring 5 is sleeved on the outer surface of the cable main body 1 in a sliding mode, the outer surface of the sealing ring 5 is in dynamic sealing with the inner wall of the wire protecting sleeve 2, a pressing head 7 is further arranged at one end of the wire protecting sleeve 2, the pressing head 7 is divided into an upper group and a lower group, and a rectangular through groove which is convenient for the pressing head to deflect is formed between the two groups of pressing heads 7.

Further, the outer surface of the pressing plate 4 and the inner wall of the pressing head 7 are provided with a plurality of groups of bulges 8, and the bulges 8 are of arc-shaped structures.

Further, the outer surface of the pressing head 7 is provided with an inclined chamfer.

Further, the surface of the threaded ring 3 is provided with a threaded through hole, and a fastening screw 6 is screwed in the threaded through hole through threads.
