Multiple protection cables

Abstract

The invention discloses a multi-protection cable, which comprises an outer protective layer, an installation cavity is provided in the outer protection layer, and more than one strand of cable core wires are installed in the installation cavity, and the outer wrapping of more than one strand of cable core wires is arranged in an inner layer. Protective layer, the outer protective layer is provided with more than one through groove, each through groove extends toward the length direction of the outer protective layer, more than one through groove is set around the circular outer protective layer, each through groove Both the direction and the radial direction are arranged at intervals, and each through groove is provided with a movable protection part outside, and the bottom of the movable protection part is fixedly provided with more than one elastic belt, and the more than one elastic belt is stretched. The cable of the present invention has very good protection performance, and can automatically close the outer protective layer after being sheared and damaged, and has the function of internal secondary automatic protection, which greatly increases the safety of the cable.

Description

Technical field [0001] The present invention relates to the field of cable, and more particularly to a multiple protection cable. Background technique [0002] Cable applications are in many occasions, but there are large risks in many environments. Due to the single, the cable structure is single, generally only includes the outer protective layer and the inner core wire, so this structure is generally protected in order to increase protection. The layers will set some reinforcing structures to prevent the external protective layer from being easily damaged, but although the reinforcing structure is set, the cable outside the cable will be used for various reasons, which will be damaged after it is destroyed, causing the outside. Water vapor and dust enter the internal, corrosion cable, etc., reduce service life, once the outer protective layer is destroyed, the internal core wire will be destroyed, the service life is short. Inventive content [0003] The technical problem to ...

Problems solved by technology

[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
