Multi-protection cable

Abstract

The invention discloses a multi-protection cable. The multi-protection cable comprises an outer protective layer, a mounting cavity is formed in the outer protective layer; more than one strand of cable core wire is mounted in the mounting cavity; more than one strand of cable core wire is wrapped with an inner protective layer; more than one through groove is formed in the outer protective layer;each through groove extends towards the length direction of the outer protective layer; more than one through groove is formed around the round outer protection layer for a circle, the through grooves are formed at intervals in the axial direction and the radial direction, a movable protection part is arranged outside each through groove, more than one elastic band is fixedly arranged at the bottom of each movable protection part, and the elastic bands are all in a stretching shape. The cable provided by the invention has very high protection performance, can automatically close the outer protection layer after being damaged by shearing, and has an internal secondary automatic protection function, so that the use safety of the cable is greatly improved.

Description

technical field [0001] The invention relates to the field of cables, in particular to a multi-protection cable. Background technique [0002] Cables are used in many occasions, but the cables used in many environments have greater risks. Because the cable structure is single, it generally only includes the outer protective layer and the inner core wire. Therefore, in order to increase the protection ability of this structure, the general outer protection Layers will be equipped with some reinforcement structures to prevent the outer protective layer from being easily damaged, but despite the reinforcement structure, the outer layer of the cable will be damaged due to various reasons after a long period of use, and holes will be left after the damage, resulting in external damage. Water vapor and dust enter the interior, corroding the inner core wire of the cable, etc., which reduces the service life. Once the outer protective layer is damaged, the inner inner core wire will ...

[0002] Cables are used in many occasions, but the cables used in many environments have greater risks. Because the cable structure is single, it generally only includes the outer protective layer and the inner core wire. Therefore, in order to increase the protection ability of this structure, the general outer protection Layers will be equipped with some reinforcement structures to prevent the outer protective layer from being easily damaged, but despite the reinforcement structure, the outer layer of the cable will be damaged due to various reasons after a long period of use, and holes will be left after the damage, resulting in external damage. Water vapor and dust enter the interior, corroding the inner core wire of the cable, etc., which reduces the service life. Once the outer protective layer is damaged, the inner inner core wire will also be damaged immediately, and the service life is shorter
