[0016] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the embodiments will be briefly described below.

[0017] Figure 1 This is a schematic diagram of the structure of the optoelectronic hybrid cable in one embodiment of the present invention. Detailed Implementation

[0018] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0019] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0020] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] Current USB data transfer cables suffer from limitations in long-distance transmission, and their internal structure consists of multiple pairs of high-speed signal differential pairs, resulting in a relatively large size.

[0022] To address the aforementioned issues, this application provides a hybrid optoelectronic cable that can reduce cable size while overcoming the limitations of long-distance transmission.

[0023] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 1 A hybrid optical and electrical cable includes: a cable core 100, a first braided layer 200 and an outer sheath layer 300 arranged sequentially from the inside to the outside. The cable core 100 includes an optical cable assembly 110, which includes an optical fiber unit 111 and an outer sheath layer 112. The outer sheath layer 112 covers the optical fiber unit 111.

[0025] It should be noted that the cable core 100 is used to transmit current or signals, the first braided layer 200 serves to block electromagnetic interference and prevent signal leakage, and the outer sheath layer 300 protects the cable from mechanical damage, wear, or impacts from external objects. It also isolates the cable from moisture, dampness, oil, chemicals, and ultraviolet radiation, preventing internal structural failure due to corrosion or aging. Furthermore, the optical cable assembly 110 is a 4-core multimode optical fiber, meaning it has 4 fiber units 111, replacing the traditional 4 pairs of differential high-speed pairs. This significantly reduces the cable size, as well as the overall copper wire usage, weight, and cost. Secondly, optical fiber has the characteristics of long-distance transmission, interference resistance, and low latency, which can solve the problem of limited long-distance transmission in traditional data transmission cables.

[0026] It should also be noted that this application removes the aluminum foil shielding used in cable production. Secondly, a new production process is adopted: 100% untwisting and unwinding of semi-finished products to form cables eliminates the internal stress generated during stranding in the semi-finished cable production, thereby increasing the overall flexibility of the cable and reducing its impact on optical fiber performance.

[0027] Please see Figure 1 In one embodiment, a receiving cavity 210 is formed on the first braided layer 200, and the cable core 100 further includes a plurality of first conductors 120, each of which is disposed at intervals within the receiving cavity 210. Specifically, the radii of each first conductor 120 are the same.

[0028] It should be noted that the first conductor 120 has four wires, which can be made of copper wire, and are used to transmit signals or current.

[0029] Please see Figure 1 In one embodiment, the cable core 100 further includes a second conductor 130 disposed within the receiving cavity 210.

[0030] Please see Figure 1 In one embodiment, the cable core 100 further includes a third conductor 140 disposed within the receiving cavity 210.

[0031] It should be noted that the second conductor 130 and the third conductor 140 can be made of copper wire and are used to transmit signals or current.

[0032] Please see Figure 1 In one embodiment, the cable core 100 further includes a first filler wire group 150 disposed within the receiving cavity 210. Specifically, the cable core 100 further includes a second filler wire group 160 disposed within the receiving cavity 210.

[0033] It should be noted that the first filler wire group 150 and the second filler wire group 160 can fill the gaps between the conductors, keeping the cable cross-section round and preventing damage to the internal structure due to compression deformation. They also absorb external pressure and vibration, reduce friction between the wire cores, and improve the cable's flexibility and durability.

[0034] Please see Figure 1 In one embodiment, the cable core 100 further includes a drain wire assembly 170, which is disposed within the receiving cavity 210.

[0035] It should be noted that the drain cable assembly 170 is used to discharge static electricity, preventing the accumulation of static electricity in the cable caused by friction, induction, etc., and avoiding electrostatic discharge breakdown of the insulation layer or interference with signal transmission. In addition, the drain cable assembly 170 provides a low-impedance grounding path for the first braided layer 200, enhancing the electromagnetic shielding effect.

[0036] Please see Figure 1 The optoelectronic hybrid cable also includes a second braided layer 400, which covers the outer sheath layer 300. Specifically, the second braided layer 400 is woven from flame-retardant nylon polyester fiber.

[0037] It should be noted that this application adds an additional second braided layer 400 to the outer sheath layer 300 to protect the cable. The second braided layer 400 is woven from flame-retardant nylon polyester fiber, which gives the cable good flexibility, abrasion resistance, tear resistance and flame retardancy.
