Technical Field

The utility model relates to a cable, concretely relates to anti fluorine of cracking of falling moulds cable.

Background

Fluoroplastic cables are used for wire and cable with fluoroplastic as the outer sheath, and all plastics containing fluorine atoms in their molecular structure are collectively called fluoroplastic (or fluorocarbon resin). The existing fluoroplastic cable is usually characterized in that a fire-resistant layer is added outside an insulating layer for improving fire resistance, although the fire resistance of the fluoroplastic cable is improved, the cable still has the problem of breakage, the cable breakage easily causes conductor short circuit, the temperature rises to reach the ignition point of the insulating layer so as to trigger ignition, and the combustion of the insulating layer can bring about greater fire spread and cause greater direct and indirect loss.

Therefore, it is necessary to provide a technical means to solve the above-mentioned drawbacks.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

Please refer to fig. 1 and fig. 2, for the embodiment provided by the present invention, and the fluoroplastic cable with anti-drop and anti-crack in the embodiment is used for data information transmission of electronic products, the fluoroplastic cable in the embodiment includes a cable body 1, wherein the cable body 1 includes core wires 4 and a protective sleeve 2, the protective sleeve 2 is sleeved on the outer surface of the core wires 4, so that the corresponding core wires 4 are configured to have the predetermined transmission parameters, and the following further explains the components of the fluoroplastic cable:

the outer surface of the protective sleeve 2 is provided with a plurality of protruding structures 21 along the length of the protective sleeve 2, the plurality of protruding structures 21 are circumferentially distributed along the protective sleeve 2, and a heat dissipation groove is arranged between two adjacent protruding structures 21; within the lug structure 21 is a rigid tensile member 22. Therefore, by improving the structure of the protective sheath 2, the anti-friction and anti-falling performance of the cable can be improved, and the heat dissipation area of the protective sheath 2 can also be increased.

Preferably, the protruding structure 21 is a rectangular protruding strip.

Further, the outer surface of 4 groups of heart yearns still the cladding around band 3, around the surface of band 3 and the internal surface connection of protective sheath 2.
