Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the attached drawings.

Referring to fig. 1 to 3, a flexible cable is used to solve the problems that the cold resistance of a conventional cable is poor, the cable is embrittled by the influence of temperature in a subzero environment for a long time, the flexibility of the cable is reduced, and even the cable is broken.

As a further proposed technical solution of the present invention, the cable sheath comprises a cable sheath 1, an inner cavity 1.2 is formed on the cable sheath 1, as shown in the state of fig. 3, a powder filling layer 1.4 is filled in the inner cavity 1.2, the powder filling layer 1.4 is specifically a powder butyronitrile, a plurality of groups of first protrusions 1.1 are arranged on the inner wall of the inner cavity 1.2 along the axial direction, as shown in the state of fig. 2, every eight first protrusions 1.1 are in one group, and a certain distance exists between every group of first protrusions 1.1, and the distance of the distance is set according to the needs of the technicians in the field, further, a second protrusion 1.3 is relatively arranged on one side of each first protrusion 1.1 of the inner cavity 1.2, each second protrusion 1.3 is abutted to the first protrusion 1.1, and a certain extrusion is performed on the inner cavity 1.2 by the abutment of the two, specifically, the publicly known powder butyronitrile can increase the tensile strength, weather resistance, cold resistance and the like of the product, and the smaller the particle size of the powder butyronitrile is, the better the reinforcing effect on the sizing material is, therefore, when the cable sheath 1 is bent, in the deformation process, when the bending point makes the first bulge 1.1 and the second bulge 1.3 in one group abut against each other, the powder butyronitrile filled in the inner cavity 1.2 can be extruded at the same time, and then the powder butyronitrile is extruded through the space of the extrusion inner cavity 1.2, so that the particle size of the powder butyronitrile is smaller, the overall cold resistance of the cable is improved, and the embrittlement of the cable caused by the influence of temperature is weakened and even avoided.
