Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an anti-extrusion cable filling rope. Background Art

[0002] Cables are usually rope-like wires made of several or several groups of conductors twisted together. Each group of conductors is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. Cables are generally required to have a round appearance, so fillers are added to the gaps inside the conductors. For wire products that require roundness in appearance, whether the cable core wire is round is the key, and filling ropes are generally added to the gaps in the cable.

[0003] The existing technology has the following problems:

[0004] During the actual laying process of existing cables, they are easily crushed by external objects, and the filling ropes inside the cables are also subjected to crushing pressure. During the twisting process of the filling ropes, it is inevitable that there will be a certain cavity structure, which causes the final filling rope to be not dense enough and easily deformed after being compressed, causing fatigue and reducing the service life.

[0005] To this end, we proposed an anti-extrusion cable filling rope to solve the above-mentioned drawbacks. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and has the advantage of anti-extrusion, and proposes an anti-extrusion cable filling rope.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-extrusion cable filling rope, comprising an inner conductor and a single-strand rope body, an outer surface of the inner conductor is provided with an arc groove, a single-strand rope body is arranged at the arc groove, and multiple strands of the single-strand rope body are arranged on the outer side surface of the inner conductor by twisting.

[0008] Preferably, a plurality of arc-shaped grooves are provided, and the plurality of arc-shaped grooves are spirally provided on the outer side surface of the inner conductor.

[0009] Preferably, the inner conductor is made of stainless steel.

[0010] Preferably, a shielding layer is provided on the outer side of the single-strand rope body, and a flame-retardant layer is provided on the outer side of the shielding layer.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The utility model provides an inner conductor between a plurality of single-strand rope bodies, thereby making the filling rope more compact and increasing the contact surface between the filling ropes through the inner conductor. When the filling rope is subjected to an extrusion force, the large contact surface can disperse the extrusion force, making it less likely to deform during use, thereby reducing the damage to the filling rope during use and extending its service life, thereby facilitating improving the overall tensile strength of the filling rope.

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] Please refer to Figure 1-3 An anti-extrusion cable filling rope comprises an inner conductor 1 and a single-strand rope body 2. An arc groove 3 is opened on the outer surface of the inner conductor 1, and a single-strand rope body 2 is arranged at the arc groove 3. Multiple single-strand rope bodies 2 are arranged on the outer side of the inner conductor 1 by twisting.

[0021] In the present embodiment: an inner conductor 1 is provided between a plurality of single-strand rope bodies 2, so that the filling rope is made denser, and the contact surface between the inner conductor 1 is increased. When the filling rope is subjected to an extrusion force, the large contact surface can disperse the extrusion force, and the filling rope is not easily deformed during use, thereby reducing the use damage of the filling rope and extending the service life, thereby facilitating improving the overall tensile strength of the filling rope.

[0022] Specifically, a plurality of arc-shaped grooves 3 are provided, and the plurality of arc-shaped grooves 3 are spirally provided on the outer side surface of the inner conductor 1 .

[0023] In this embodiment, the twisting of the single-strand rope body 2 is guided and limited.

[0024] Specifically, the inner conductor 1 is made of stainless steel.

[0025] In this embodiment, it has the characteristics of corrosion resistance and not easy to be damaged.

[0026] Specifically, a shielding layer 5 is disposed on the outer side of the single-strand rope body 2 , and a flame-retardant layer 4 is disposed on the outer side of the shielding layer 5 .

[0027] In this embodiment, the shielding layer 5 and the flame retardant layer 4 are provided to provide auxiliary shielding and flame retardant effects on the cable.

[0028] Working principle: By arranging an inner conductor 1 between multiple single-strand rope bodies 2, the filling rope is made denser, and the contact surface between them is increased by the inner conductor 1. When the filling rope is subjected to extrusion pressure, the large contact surface can disperse the extrusion pressure, and it is not easy to deform during use, which reduces the damage of the filling rope and extends its service life, thereby helping to improve the overall tensile strength of the filling rope.
