Embodiment Construction

[0012] Such as figure 1 It is a structural schematic diagram of the present invention, a protective cable, including a cable core 1 and a sheath 2, the sheath 2 is wrapped on the outer surface of the cable core 1, and the outer surface of the sheath 2 is wrapped with a reinforcing sheath 3. The reinforcing sleeve 3 is a circular rubber sleeve. The reinforcing sleeve 3 is provided with a through hole 4 . The through holes 4 are evenly distributed in the circumferential wall of the reinforcement sleeve 3 .

[0013] A rubber reinforcing sleeve 3 with a through hole 4 is installed on the outside of the sheath 2, which not only increases the protective thickness of the cable, but also can buffer and transfer external forces. When an external force is applied, the through hole 4 is elastically deformed and becomes oblate. The active force is diverged to both sides, thereby avoiding the direct impact of the external force on the cable core 1 and effectively protecting the cable.

Abstract

The invention relates to the technical field of wires and cables, particularly to a protective cable. The protective cable comprises a cable core and a sheath. The sheath wraps an external surface of the cable core. A reinforcing sleeve wraps an external portion of the sheath. The rubber reinforcing sleeve with a through hole sleeves the external portion of the sheath, so that protection thickness of the cable is increased and external force can be buffered and transferred. While the cable is subjected to external acting force, elastic deformation of the through hole occurs and an oblate shape is formed, thereby diffusing the external force to two sides. Therefore, direct impact of the external force to the cable core is avoided and the cable is effectively protected.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a protective cable. Background technique [0002] With the development of society, more and more cables are used, and the application fields are more and more extensive, and the requirements for cable types and performance are also getting higher and higher. Composed of plastic and rubber organic polymers, generally one layer, when used in some environments, the protection of the cable core is not strong enough, the cable core is easily damaged, and the normal use of the cable is affected. Contents of the invention [0003] In order to overcome the disadvantages of low protective performance and easily damaged cable cores in the existing cables, the invention provides a protective cable. [0004] The technical solution adopted by the present invention to solve the technical problem is: a protective cable, including a cable core and a sheath, the sheath is wra...
