In addition, unless clearly defined in the text, terms such as those defined in a general dictionary should be interpreted as having a meaning consistent with their meaning in the relevant art and the content of this application, and will not be interpreted as idealized or overly formal meanings.

[0045] The following further describes in detail the specific embodiments of the present application with reference to the accompanying drawings.

[0046] As Figure 1 shown, this embodiment provides an optical and electrical composite cable 100, including an optical unit 10 and an electrical unit 20. The optical unit 10 and the electrical unit 20 are combined within a single cable, enabling the single cable to support the transmission of both optical signals and electrical signals simultaneously. This not only allows users to reduce the number of cables during wiring, thereby saving space and reducing installation costs, but also meets complex communication requirements and improves the applicable scenarios of the cable.

[0047] The optical and electrical composite cable 100 further includes an outer sheath 30, a support member 50, and a water-blocking member 60. The optical unit 10 and the electrical unit 20 are disposed within the outer sheath 30, and the outer sheath 30 protects the optical unit 10 and the electrical unit 20. The support member 50 is disposed within the outer sheath 30, and at least a part of the outer peripheral surface of the support member 50 abuts against the inner peripheral surface of the outer sheath 30 to support the outer sheath 30 through the support member 50 and prevent the outer sheath 30 from bending and deforming. A plurality of receiving grooves 54 are provided on the support member 50. Some of the plurality of receiving grooves 54 receive the optical unit 10, and another part of the plurality of receiving grooves 54 receive the electrical unit 20, so as to accommodate the optical unit 10 and the electrical unit 20 through the support member 50 and limit the optical unit 10 and the electrical unit 20 by the support member 50.

[0048] A plurality of through holes 53 are provided on the support member 50, and the extending direction of the through holes 53 is parallel to the extending direction of the support member 50. Each of the plurality of through holes 53 receives a water-blocking member 60. The water-blocking member 60 is a material with a water-blocking function such as water-blocking yarn, which can absorb moisture or humidity entering the outer sheath 30 and prevent moisture or humidity from entering the receiving grooves 54 and affecting the normal operation of the optical unit 10 and the electrical unit 20.

[0049] Thus, for the optical and electrical composite cable 100 of the present application, by providing a support member 50 inside the outer sheath 30, the support member 50 abuts against the outer sheath 30 to support the outer sheath 30, and the optical unit 10 and the electrical unit 20 are accommodated in the accommodation groove 54 formed in the support member 50. The support member 50 positions the optical unit 10 and the electrical unit 20, thereby improving the structural strength of the entire optical and electrical composite cable 100 and enhancing the bending resistance of the optical and electrical composite cable 100. In addition, a plurality of through holes 53 are formed in the support member 50, and a water blocking member 60 is inserted into the through holes 53, which can utilize the space occupied by the support member 50 to improve the waterproof performance of the optical and electrical composite cable 100 and enhance the compactness of the internal structure of the optical and electrical composite cable 100.

[0050] Please refer to Figure 1 In an embodiment, the outer sheath 30 is in the shape of a hollow cylinder. The material of the outer sheath 30 is polyvinyl chloride or a low-smoke and halogen-free mixture, which has an anti-ultraviolet function and a rodent-proof function, and can ensure the safety of the optical and electrical composite cable 100 during use.

[0051] Furthermore, the optical and electrical composite cable 100 further includes a shielding layer 40, and the shielding layer 40 is also in the shape of a hollow cylinder. The shielding layer 40 is disposed between the support member 50 and the outer sheath 30, and the outer sheath 30 is wrapped around the outer peripheral surface of the shielding layer 40. At least a part of the outer peripheral surface of the support member 50 abuts against the inner peripheral surface of the shielding layer 40, and the support member 50 applies a force to the outer sheath 30 in contact with the shielding layer 40 by abutting against the shielding layer 40, so that the support member 50 supports the outer sheath 30.

[0052] In this embodiment, the shielding layer 40 is a metal shielding tape. Wrapping the shielding layer 40 around the outer periphery of the optical unit 10 and the electrical unit 20 can effectively shield external electromagnetic interference and prevent external electromagnetic interference signals from affecting the signal transmission of the optical unit 10 and the electrical unit 20.

[0053] Please refer to Figure 1 In an embodiment, the support member 50 includes a central portion 51 and a plurality of support portions 52. The central portion 51 is in a shape such as a circle or a square, and its specific shape can be selected according to actual design requirements.

[0054] The central portion 51 is disposed inside the outer sheath 30. Specifically, the central portion 51 is disposed in the space surrounded by the shielding layer 40, and the center point of the central portion 51 coincides with the axis of the outer sheath 30. The outer peripheral surface of the central portion 51 is spaced apart from the inner peripheral surface of the shielding layer 40.

[0055] A plurality of support portions 52 are arranged around the outer circumference of the central portion 51, one end of the support portion 52 is integrally connected to the outer circumference of the central portion 51, and the other end of the support portion 52 extends to the side away from the central portion 51 to abut against the inner circumference of the shielding layer 40, so that the outer sheath 30 is supported along its circumferential direction by the plurality of support portions 52 at the same time, not only making the outer sheath 30 evenly stressed, but also preventing the outer sheath 30 from bending at any area of ​​its outer circumference. A through hole 53 is provided on both the support portion 52 and the central portion 51, and the through hole 53 passes through the support portion 52 and the central portion 51 along the direction of the axis of the outer sheath 30.

[0056] A plurality of support portions 52 are arranged at intervals around the axis of the central portion 51, and a receiving groove 54 is formed between any two adjacent support portions 52. The optical unit 10 and the electrical unit 20 are received in different receiving grooves 54, and when the optical unit 10 and the electrical unit 20 are located in the receiving grooves 54, the optical unit 10 and the electrical unit 20 are clamped between the support member 50 and the shielding layer 40 to limit the optical unit 10 and the electrical unit 20.

[0057] In particular, the shape of the groove wall of the receiving groove 54 on the side away from the outer sheath 30 is a curved surface, so that when the optical unit 10 and the electrical unit 20 are located in the receiving groove 54, the optical unit 10 and the electrical unit 20 can be tightly attached to the groove wall of the receiving groove 54 on the side away from the outer sheath 30, thereby avoiding deformation of the optical unit 10 and the electrical unit 20 when clamped between the support member 50 and the shielding layer 40.

[0058] It is understandable that, in some embodiments, the outer diameter of the optical unit 10 is different from the outer diameter of the electrical unit 20, and the shape or size of the receiving groove 54 where the optical unit 10 is located is different from that of the receiving groove 54 where the electrical unit 20 is located, so as to ensure that both the optical unit 10 and the electrical unit 20 can be clamped between the support member 50 and the shielding layer 40. Thus, those skilled in the art can design the shape of the support member 50 according to the respective sizes of the optical unit 10 and the electrical unit 20, for example, adjusting the shape and size of each support portion 52, so that the support member 50 can form the receiving grooves 54 respectively adapted to the optical unit 10 and the electrical unit 20.

[0059] In this embodiment, along the radial direction of the outer sheath 30, the distribution density of the perforations 53 on the support member 50 increases gradually from the center point of the support member 50 to the side of the support member 50 close to the outer sheath 30, so that more water-blocking members 60 are penetrated in the area of ​​the support member 50 close to the shielding layer 40, thereby improving the waterproof performance between the support member 50 and the shielding layer 40.

[0060] In this embodiment, along the radial direction of the outer sheath 30, the aperture diameter of the perforations 53 on the support member 50 increases from the center point of the support member 50 to the side of the support member 50 close to the outer sheath 30, so that more water-blocking members 60 are passed through the area of the support member 50 close to the shielding layer 40, thereby improving the waterproof performance between the support member 50 and the shielding layer 40.

[0061] Please also refer to Figure 1 , in one embodiment, the optical and electrical composite cable 100 further includes a filling member 70. Each of the plurality of receiving grooves 54 receives one of the optical unit 10, the electrical unit 20, and the filling member 70. The filling member 70 is a non-hygroscopic filling material 12 such as a filling rope. The filling member 70 is filled in the receiving grooves 54 that do not receive the optical unit 10 or the electrical unit 20, so as to make the entire outer sheath 30 filled and rounded.

[0062] The number of the optical units 10 is at least one, and each of the at least one optical units 10 is respectively received in one receiving groove 54. The number of the electrical units 20 is at least two, and each of the at least two electrical units 20 is respectively received in one receiving groove 54.

[0063] In this embodiment, the number of the optical units 10 is one, and the number of the electrical units 20 is two. The number of the support portions 52 is four, and four receiving grooves 54 are formed. Among them, one receiving groove 54 receives one optical unit 10, two receiving grooves 54 respectively receive one electrical unit 20, and the remaining one receiving groove 54 receives the filling member 70.

[0064] It can be understood that in other embodiments, the number of the optical units 10 can also be two or more, the number of the electrical units 20 can also be three or more, and the numbers of the optical units 10 and the electrical units 20 can be selected according to actual design requirements. The number of the receiving grooves 54 is the same as the total number of the optical units 10 and the electrical units 20, or the number of the receiving grooves 54 is greater than the total number of the optical units 10 and the electrical units 20, and the filling member 70 is provided in the receiving grooves 54 that do not receive the optical units 10 and the electrical units 20.

[0065] Please also refer to Figure 1 , in one embodiment, the optical unit 10 includes a protective sleeve 13, a plurality of optical fibers 11, and a filling material 12.

[0066] The shape of the protective sleeve 13 is a hollow cylinder, and the protective sleeve 13 is made of PBT (polybutylene terephthalate) loose tube. The plurality of optical fibers 11 are arranged in the protective sleeve 13, so that the protective sleeve 13 protects the optical fibers 11 from internal stress and external lateral pressure, and at the same time provides good waterproof performance.

[0067] The filling 12 is disposed within the protective sleeve 13 and is filled into the gap between the optical fiber 11 and the adjacent optical fiber 11 or between the optical fiber 11 and the protective sleeve 13, thereby fixing the optical fiber 11. The filling 12 is a fiber paste, which can be made of materials such as silica gel or epoxy resin. While fixing the optical fiber 11, the filling 12 can also protect the optical fiber 11 from being damaged or corroded.

[0068] In this embodiment, the number of the multiple optical fibers 11 is eight, and the eight optical fibers 11 are all colored optical fibers 11, so as to directly distinguish the eight optical fibers 11 from the appearance.

[0069] It can be understood that in other embodiments, the number of the optical fibers 11 can also be four, six or other numbers, and the specific number of the optical fibers 11 can be selected according to the actual design requirements.

[0070] Please also refer to Figure 1 In an embodiment, the electrical unit 20 includes a plurality of conductive wires 21 and an insulating layer 22. The plurality of conductive wires 21 are all made of conductive wires such as copper wires, and the insulating layer 22 is made of an insulating material, such as a 105°C low-smoke, halogen-free, flame-retardant irradiated cross-linked material, which has a relatively high temperature resistance level and ensures the safety during the use of the electrical unit 20. The insulating layer 22 is coated on the outer peripheral surface of the plurality of conductive wires 21 to form an insulating environment on the outer periphery of the plurality of conductive wires 21.

[0071] In this embodiment, the electrical unit 20 is composed of five types of stranded conductors to be suitable for complex application scenarios. Specifically, the number of the plurality of conductive wires 21 is five, and the five conductive wires 21 are stranded with each other. The functions of the five conductive wires 21 can be different from each other. For example, some of the conductive wires 21 are used for power transmission, some are used for low-frequency signal transmission, some are used for high-frequency signal transmission, and some are used for control signal transmission.

[0072] In the above text, the specific embodiments of the present application have been described with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that various changes and substitutions can be made to the specific embodiments of the present application without departing from the scope of the present application.
