Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "fixed" 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. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a high-flexibility wear-resistant shielded cable comprises a tensile rib 1 positioned in the center of the cable, a plurality of core wires 2 are twisted in pairs and are arranged around the tensile rib 1 in an extending mode, an harness sheath 3 is designed on the outer side of the core wires 2 through an extrusion molding process, a layer of fiber belt 31 is spirally wound on the outer side of the harness sheath 3, a metal wire weaving layer 4 is arranged on the outer side of the fiber belt 31, a layer of outer protective sleeve 5 is wrapped on the metal wire weaving layer 4, and a plurality of wear-resistant spiral leather strips 51 are arranged on the outer side of the outer protective sleeve 5. Specifically, in this embodiment, set up a metal anti-lacing wire 1 in the cable middle part, anti-lacing wire 1 structural strength is high, can not break easily, and synchronous convenience twines heart yearn 2 with this anti-lacing wire 1, and the two liang of transposition of heart yearn 2 are in the same place, not only can improve the whole stress bearing capacity of cable, effectively prevent heart yearn 2 not hard up simultaneously, makes the wiring fastening of heart yearn 2 firm, prevents that the connection of cable is insecure. In this embodiment, in order to provide necessary support for the stranded core wire 2, the extruded harness sheath 3 is used to replace the original tubular sheath, and the harness sheath 3 is made of polyethylene material, because the harness sheath 3 is extruded by an extruder under a particularly large pressure outside the core wire 2, and is similar to an integrally formed guide groove, to guide the movement of the core wire 2, and also to provide a supporting function, so that the cable can provide necessary support for the structure of the stranded core wire 2 during frequent bending, prevent the stranded core wire 2 from being split, and ensure that the core wire 2 will not be loosened during the movement of the cable.
