Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "plurality" or "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a can resist high atmospheric pressure and high water pressure's cable, includes wire 1, and 1 covers of wire is established in insulating filler 2, and the peripheral department cover of insulating filler 2 is equipped with shielding canning 3, and the peripheral department cover of shielding canning 3 is equipped with first insulating layer 4, increases the insulating nature and the signal shielding nature of cable. The first set of strip 5 that is the heliciform of the peripheral winding of first insulating layer 4, first set of strip 5 is formed with first filling joint 51 when rolling up, it has first joint strip 52 to fill in first filling joint 51, the peripheral cover of first set of strip 5 is equipped with second insulating layer 6, the peripheral winding of second insulating layer 6 has the second set of strip 7 that is the heliciform, second set of strip 7 is formed with second filling joint 71 when rolling up, it has second joint strip 72 to fill in the second filling joint 71, the peripheral cover of second set of strip 7 is equipped with sheath 8. The first sleeve strip 5 and the second sleeve strip 7 are made of hard plastics, so that the external high-pressure environment acts on the surface of the sheath 8 and is transmitted to the second sleeve strip 7 and the first sleeve strip 5, the external high-pressure environment can be uniformly distributed on the surfaces of the second sleeve strip 7 and the first sleeve strip 5, and the pressure resistance of the cable is improved.

In this embodiment, wire 1 includes crust 11 and the metal core 12 of cover establishing in crust 11, and wire 1 is the annular equidistant arrangement in insulating filler 2's inside, and each other does not contact between two adjacent wires 1, makes to be the isolated state between sinle silk 1 and the sinle silk 1, further increases insulating nature.

Specifically, first cover strip 5 and second cover strip 7 all are sheet structure and closely wrap up in the outside of first insulating layer 4 and second insulating layer 6 respectively, make first cover strip 5 and second cover strip 7 protect first insulating layer 4 and second insulating layer 6 respectively, increase the compressive strength of cable when preventing first insulating layer 4 and second insulating layer 6 damaged.

Further, the opposite direction of the spirals of the first and second jacketing strips 5, 7 causes the first and second jacketing strips 5, 7 to be staggered in the cable, thereby increasing the strength of the cable.
