[0018] The following combination Figures 1 to 2 Embodiments of the present invention are described in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0019] In the description of the present invention, it should be understood that if the terms "center", "middle", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The features defined as "first" and "second" are used to distinguish the feature names, and do not have special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0020] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0021] The present invention relates to a cable, comprising a conductive component arranged along the length direction of the cable. Further, the cable comprises at least one sheath layer, which covers the conductive component and acts as a protective layer.

[0022] Referring to the accompanying drawings, the cable comprises two sheath layers. Specifically, the cable includes an inner sheath layer 301 and an outer sheath layer 302. It is understood that the inner sheath layer 301 is wrapped around the conductive components, while the outer sheath layer 302 is wrapped around the inner sheath layer 301. The inner sheath layer 301 is extruded around the conductive components and is made of a flame-retardant material that is resistant to high temperatures. The outer sheath layer 302 is made of an elastic material, specifically a soft, elastic hybrid material with an anti-UV agent added. The anti-UV agent is a UV additive.

[0023] Furthermore, the inner and outer sheath layers 301 and 302 are inlaid with each other, preventing deformation during repeated cable expansion and contraction. This also acts as a position limiter when the cable is stretched, improving the stability of the cable. Specifically, the outer side of the inner sheath layer 301 is provided with at least one guide groove, extending along the length of the cable. The inner side of the outer sheath layer 302 is provided with a raised structure, which is assembled with the guide groove to achieve an inlaid connection between the outer and inner sheath layers 302 and 301.

[0024] Considering that the materials of the inner jacket layer 301 and the outer jacket layer 302 have different melting points during the production process, a co-extrusion method can be used to connect the inner jacket layer 301 and the outer jacket layer 302. Of course, as an alternative, the inner jacket layer 301 and the outer jacket layer 302 can be designed to be separate and not connected, and the inner jacket layer 301 can be extruded first, and then the outer jacket layer 302 can be extruded.

[0025] With reference to the drawings, the conductive component includes an inner conductive layer 101 and an outer conductive layer 102, wherein the outer conductive layer 102 is coated on the outer surface of the inner conductive layer 101. It is understood that the sheath layer is coated on the outer surface of the outer conductive layer 102, specifically, the inner sheath layer 301 is coated on the outer surface of the outer conductive layer 102.

[0026] Inner conductive layer 101 includes multiple strands of metal conductive members, the number of which depends on the actual situation. The metal conductive members in inner conductive layer 101 are twisted together to form a solid structure, which improves the roundness of the wire and makes the cable structure more stable. The cross-sectional shape of inner conductive layer 101 can be designed and adjusted based on the requirements for the gaps between the metal conductive members. In some examples, the metal conductive members of inner conductive layer 101 are configured as soft copper wires with a tinned surface. The soft copper wires have the characteristics of good flexibility, good weather resistance, easy processing and forming, good shaping effect, not easy deformation, and acid, alkali and oil resistance.

[0027] The outer conductive layer 102 comprises multiple strands of metal conductive elements, the number of which depends on the actual situation. The metal conductive elements in the outer conductive layer 102 are stacked and interlaced to form a woven mesh. The outer conductive layer 102 is reversely wrapped around the inner conductive layer 101, improving the roundness of the wire and making the cable structure more stable. The cross-sectional shape of the outer conductive layer 102 can be designed and adjusted based on the required spacing between the metal conductive elements. In some examples, the metal conductive elements in the outer conductive layer 102 are configured as soft copper wire.

[0028] In conjunction with the accompanying drawings, the cable includes a locking member 200, which has the function of layering and limiting the cable. Specifically, the locking member 200 is set on the conductive component, and the locking member 200 is provided with a first wire hole 201 and a second wire hole 202. The inner conductive layer 101 passes through the first wire hole 201, and the outer conductive layer 102 passes through the second wire hole 202. The tensile strength of the inner conductive layer 101 and the outer conductive layer 102 is different. When the cable is stretched, the locking member 200 is used to separate the inner conductive layer 101 and the outer conductive layer 102, so that the inner conductive layer 101 and the outer conductive layer 102 can be stretched and retracted, which can effectively prevent the conductive component from deforming and being unable to retract after stretching.

[0029] The locking member 200 has a limiting effect on the inner sheath layer 301, preventing the inner sheath layer 301 and the outer sheath layer 302 from being straightened at the connection position, and preventing the inner sheath layer 301 and the outer conductive layer 102 from being misaligned or shifted during use.

[0030] In one embodiment, the inner conductive layer 101 is configured as a rigid conductive layer, and the outer conductive layer 102 is configured as a flexible conductive layer. The rigid conductive layer has a greater degree of deformation, which helps stabilize the overall structure of the cable. When the cable is not stretched, the locking member 200 is located at the leading end of the inner conductive layer 101 and the leading end of the outer conductive layer 102. When the cable is stretched for use, the locking member 200 is located at the leading end of the inner conductive layer 101 and the trailing end of the outer conductive layer 102, securing and separating the inner conductive layer 101 and the outer conductive layer 102. The locking member 200 prevents the outer conductive layer 102 from being excessively stretched, deforming and becoming unable to return to its original position.

[0031] Specifically, the locking member 200 is configured as a collar, and the hollow through-hole formed by the collar is configured as a first wire-passing hole 201. A second wire-passing hole 202 is provided on the sidewall of the collar, and at least one second wire-passing hole 202 is provided. In some examples, at least a portion of the sidewall of the collar is configured as a tapered sidewall, and the second wire-passing hole 202 is provided on the tapered sidewall. Referring to the accompanying drawings, a portion of the sidewall of the collar is configured as a tapered sidewall, with the larger diameter end of the tapered sidewall serving as the end of the collar, and the smaller diameter end of the tapered sidewall being connected to the collar.

[0032] It is understandable that the locking member 200 is configured as a metal member. Specifically, the locking member 200 is made of one of copper, aluminum, and high-chromium cast iron. In some examples, the locking member 200 is made of copper, which can spatially separate the inner conductive layer 101 and the outer conductive layer 102 at the connection point, so that the structure of the conductive component is stable. In some examples, the locking member 200 is made of aluminum, which is light and cheap. Of course, aluminum alloy can also be used. In some examples, the locking member 200 is made of high-chromium cast iron, which has good wear resistance, can reduce the friction when the inner conductive layer 101 and the outer conductive layer 102 are stretched and pulled, can withstand high temperatures, and has good oxidation resistance.

[0033] Of course, as an alternative, the locking member 200 can also be configured as a plastic member. Specifically, the locking member 200 is made of PET.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
