Description

Technical Field

[0001] The present application relates to the technical field of communication equipment, and in particular to an optoelectronic composite cable, a composite cable assembly, communication equipment, and a communication system. Background Art

[0002] With the development of fifth-generation mobile networks (5G) and future communication networks, the demand for fiber-to-the-antenna, fiber-to-the-camera, fiber-to-the-traffic light, fiber-to-the-room, fiber-to-the-ceiling, and other fiber-to-access terminal solutions is inexhaustible. Fiber-to-the-access terminal will lay the foundation for high-speed and timely communications in the intelligent era, ensuring the demand for massive amounts of information and high-quality bandwidth.

[0003] At present, butterfly-shaped optoelectronic composite cables are widely favored due to their ability to achieve simultaneous optical and electrical transmission. However, during the installation or connection process of butterfly-shaped optoelectronic composite cables, the performance of the wires or optical fibers therein may be damaged, affecting the further development of optoelectronic composite cables. Utility Model Content

[0004] The embodiments of the present application provide an optoelectronic composite cable, a composite cable assembly, a communication device, and a communication system, the purpose of which is to improve the tensile strength of the electrical unit, thereby improving the overall tensile strength of the optoelectronic composite cable and avoiding deformation or breakage of key components such as conductors and optical fibers.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, a photoelectric composite cable is provided. The photoelectric composite cable includes a sheath, an optical unit, and an electrical unit.

[0007] The sheath has a tear groove formed on its surface. The optical unit is embedded in the sheath, with the sidewalls of the tear groove extending in a direction intersecting the optical unit; the optical unit includes an optical fiber. The electrical unit is embedded in the sheath, spaced apart from the optical unit, and extending in the same direction as the optical unit; the electrical unit includes a conductive wire and a first fiber yarn, and the conductive wire and the first fiber yarn are in contact.

[0008] In the optoelectronic composite cable provided in the embodiment of the present application, by arranging a first fiber yarn in the electrical unit, a certain tensile strength can be provided by the first fiber yarn when the electrical unit is subjected to stress (such as tension), thereby sharing the stress on the conductor, reducing the probability of deformation of the conductor due to excessive stress burden, improving the tensile strength of the electrical unit and even the entire optoelectronic composite cable, optimizing the electrical performance of the optoelectronic composite cable, and improving the service life of the optoelectronic composite cable.

[0009] In a possible implementation of the first aspect, the electrical unit includes a plurality of conductive wires, the plurality of conductive wires are arranged in parallel, and the first fiber yarn is arranged in a gap enclosed by the plurality of conductive wires.

[0010] The first fiber yarn is arranged in the gap surrounded by multiple conductors, which can maximize the utilization of the design space, reduce the design space occupied by the first fiber yarn, and does not affect the miniaturization design of the optoelectronic composite cable.

[0011] In a possible implementation of the first aspect, the conductive wire is twisted with the first fiber yarn. This allows the first fiber yarn to be in close contact with the conductive wire. When the electrical unit is subjected to stress, the first fiber yarn can respond immediately, providing a tensile strength, further reducing the probability of the conductive wire breaking due to stress or the probability of a short circuit or open circuit due to excessive resistance caused by dimensional reduction.

[0012] In a possible implementation manner of the first aspect, the first fiber yarn is further arranged around the conductive wire.

[0013] By arranging the first fiber yarn around the conductor, the conductor can also be protected, the tensile strength of the electrical unit and even the optoelectronic composite cable can be improved, and the performance of the optoelectronic composite cable can be optimized.

[0014] In a possible implementation manner of the first aspect, the optical unit further includes a second fiber yarn, and the second fiber yarn is arranged around the optical fiber.

[0015] By arranging a second fiber yarn around the outer periphery of the optical fiber, the overall tensile strength of the optoelectronic composite cable can be further improved, while further improving the protection of critical and relatively fragile structural optical fibers, further reducing the probability of optical fiber breakage problems, and increasing the service life of the optoelectronic composite cable.

[0016] In a possible implementation manner of the first aspect, a diameter of the electrical unit is greater than a diameter of the optical unit.

[0017] That is, the electrical unit is thicker than the optical unit, so that during the stress process of the optoelectronic composite cable, such as the process of tension, the electrical unit can be subjected to stress first. For example, the first fiber yarn in the electrical unit can be subjected to stress first, thereby effectively reducing the stress on the optical unit, thereby avoiding damage to the key and relatively fragile structural optical fiber in the optical unit, thereby extending the service life of the optoelectronic composite cable.

[0018] In a possible implementation of the first aspect, a diameter of each wire is 0.14 mm to 0.18 mm.

[0019] In an embodiment of the present application, a first fiber yarn is provided in the electrical unit, and a part of the stress on the conductor is shared by the first fiber yarn, thereby ensuring that the electrical unit as a whole has sufficient tensile strength while reducing the stress burden that the conductor needs to bear, thereby providing space for reducing the diameter of the conductor. For example, the diameter of each conductor can be reduced to 0.14mm~0.18mm, thereby reducing the consumables of the conductor and reducing the preparation cost of the optoelectronic composite cable.

[0020] In a possible implementation of the first aspect, the first and second fiber yarns are made of one or more of aramid, carbon fiber, and glass yarn. This allows for improved tensile strength of the electrical unit while flexibly selecting different materials for different application scenarios, thereby balancing the strength and production cost of the optoelectronic composite cable.

[0021] In a possible implementation of the first aspect, the optoelectronic composite cable further includes two electrical units and an electrode identification structure. The two electrical units are disposed on either side of the optical unit. The electrode identification structure is disposed in the two electrical units, with one electrical unit on a side away from the other electrical unit.

[0022] The electrode identification structure is used to distinguish the polarity of the wires in the two electrical units. For example, the electrical unit closer to the electrode identification structure can transmit positive signals, and the electrical unit farther from the electrode identification structure can transmit negative signals.

[0023] In a possible implementation of the first aspect, the material of the sheath includes one or more of thermoplastic polyurethane, polyvinyl chloride, polydimethylsiloxane, polycarbonate, polyethersulfone, polyphenylenesulfone, fluorinated ethylene propylene copolymer, low-smoke halogen-free material, and polyamide.

[0024] That is, the sheath can be made of transparent material. While ensuring that the sheath can protect the optical unit from external damage, the transparent material sheath can also improve the aesthetics of the optoelectronic composite cable. For example, when the optoelectronic composite cable is laid in an indoor scene, it is beneficial to reduce the visibility of the optoelectronic composite cable, improve the overall aesthetics of the interior, and reduce damage to the overall coordination of the interior decoration.

[0025] In a possible implementation of the first aspect, the optoelectronic composite cable further includes a reinforcement member filled in the sheath, the extension direction of the reinforcement member is the same as the extension direction of the optical fiber, the reinforcement member is spaced apart from the optical unit, and the reinforcement member is spaced apart from the electrical unit.

[0026] Reinforcements are used to increase the strength of optoelectronic composite cables. For example, they can enhance the tensile strength of optoelectronic composite cables to prevent the optoelectronic composite cables from bending or stretching during construction, which can cause breakage of key components such as optical fibers and conductors, affecting the performance and service life of the optoelectronic composite cables.

[0027] In a second aspect, a composite cable assembly is provided, comprising a connector and the optoelectronic composite cable provided by any one embodiment of the first aspect, wherein the connector is connected to an end portion of the optoelectronic composite cable.

[0028] In a possible implementation of the second aspect, the connector is connected to the optical fiber, the wire, and the first fiber yarn in the optoelectronic composite cable, so that the first fiber yarn can improve the connection strength between the connector and the optoelectronic composite cable.

[0029] In a third aspect, a communication device is provided, comprising a plug-in structure and the composite cable assembly provided in the second aspect, wherein the plug-in structure is connected to the composite cable assembly.

[0030] According to a fourth aspect, a communication system is provided, comprising at least one communication device provided in the third aspect.

[0031] The technical effects brought about by the composite cable assembly in the second aspect, the communication equipment in the third aspect and the communication system in the fourth aspect can refer to the technical effects brought about by the design method of the optoelectronic composite cable in the first aspect, and will not be repeated here.

[0051] This embodiment of the application provides a communication system 1000, Figure 1 A schematic structural diagram of a communication system 1000 provided in an embodiment of the present application.

[0052] like Figure 1 As shown, the communication system 1000 includes at least one communication device 500 .

[0053] Exemplarily, the communication system 1000 may be any type of long-distance optical communication system using the optical-electrical composite cable 100 as a communication carrier.

[0054] For example, the communication system 1000 may be a metropolitan area optical network system, a wide area optical network system, or other local area optical network systems.

[0055] The embodiment of the present application also provides a communication device 500 .

[0056] like Figure 1 As shown, the communication device 500 includes a plug structure 400 and a composite cable assembly 300 .

[0057] See Figure 1 The plug-in structure 400 is connected to the composite cable assembly 300, for example, the two are plugged in.

[0058] For example, see Figure 1 , two different communication devices 500 can be electrically connected through the composite cable assembly 300, thereby achieving communication between the different communication devices 500.

[0059] For example, the composite cable assembly 300 can realize the transmission of optical signals between the optical network unit (ONU) and the optical line terminal (OLT) in each room, thereby sinking the optical network unit to the household, ensuring that each room has a stable network point, thereby realizing fiber to the room (FTTR).

[0060] Exemplarily, the communication device 500 may be an optical fiber transmission device such as an optical line terminal, an optical terminal, or an optical switch.

[0061] The embodiment of the present application further provides a composite cable assembly 300 .

[0062] See Figure 1 The composite cable assembly 300 includes an optical fiber composite cable 100 and a connector 200 . The connector 200 is electrically connected to an end of the optical fiber composite cable 100 .

[0063] Exemplarily, the connector 200 can be a pre-installed connector, that is, the connector can be pre-set at both ends of the optoelectronic composite cable 100, so that during the assembly process, the optoelectronic composite cable 100 can be simply connected to the plug-in structure 400 in the communication equipment 500 through the pre-installed connector, thereby effectively improving the construction efficiency of the connection of the optoelectronic composite cable 100.

[0064] The embodiment of the present application further provides an optoelectronic composite cable 100 .

[0065] Figure 2 A structural diagram of the optical-electrical composite cable 100 provided in an embodiment of the present application is shown in FIG. Figure 3FIG. 1 is a cross-sectional view perpendicular to the first direction X of the optical / electrical composite cable 100 .

[0066] For example, the optoelectronic composite cable 100 provided in the embodiment of the present application can be used for placement in a corridor or in a room. The embodiment of the present application does not limit the installation location of the optoelectronic composite cable 100.

[0067] In some embodiments, as Figure 2 and Figure 3 As shown, the optical-electrical composite cable 100 may include a jacket 10 , an optical unit 20 and an electrical unit 30 .

[0068] Among them, see Figure 2 and Figure 3 The sheath 10 is disposed outside the optical unit 20 and the electrical unit 30 .

[0069] The sheath 10 serves as the first barrier to protect the optical fiber 21 and the wire 31 from external damage, and has good mechanical reinforcement and corrosion resistance.

[0070] For example, the sheath 10 may include a multi-layer structure that is nested together. For example, the different layers of the sheath 10 may be made of different materials. For example, one layer may be a metal layer, such as a metal wire or a metal tape, which provides good mechanical support. For example, the structures disposed inside and outside the metal layer may both be made of corrosion-resistant materials. For example, the outermost layer of the sheath 10 may be made of a flame-retardant material.

[0071] See Figure 2 The sheath 10 is wrapped around the entire extension direction of the optical fiber 21 and the wire 31, thereby protecting all positions of the optical fiber 21 and the wire 31.

[0072] When the optoelectronic composite cable 100 is installed, it is necessary to tear off part of the sheath 10 around the ends of the optical unit 20 and the electrical unit 30 so that the ends of the optical fibers 21 and the ends of the wires 31 are exposed to the outside, thereby facilitating the fiber fusion connection between the optical fibers 21, or the connection and installation of the optical fibers 21 with structures such as connectors, as well as the electrical connection between the wires 31 and other conductive structures.

[0073] See Figure 2 and Figure 3 A tearing groove U is provided on the surface of the sheath 10.

[0074] The provision of the tearing groove U can facilitate the peeling of the sheath 10. The sheath 10 can be torn apart along the tearing groove U to expose the ends of the optical fibers 21 and the wires 31 embedded in the sheath 10, so as to facilitate operations such as fiber fusion between the optical fibers 21 and the electrical connection of the wires 31 with other structures, thereby realizing the connection and installation of the optoelectronic composite cable 100.

[0075] For example, Figure 2 As shown, the length extension direction of the tearing groove U is the same as the extension direction of the optical fiber 21, that is, the tearing groove U extends along the first direction X, thereby ensuring that the sheath 10 can be torn and peeled off at any position of the optical fiber 21 and the wire 31 in the length direction, thereby facilitating the connection and fixation of the optoelectronic composite cable 100 at any position of the optoelectronic composite cable 100.

[0076] Exemplarily, there may be multiple tear grooves U, for example, Figure 3 Based on the orientation in, at least one tearing groove U can be provided on both the upper and lower surfaces of the sheath 10, so that during the installation and connection of the optoelectronic composite cable 100, the sheath 10 can be smoothly torn to expose the optical fiber 21 and the wire 31.

[0077] See Figure 2 and Figure 3 The optical unit 20 is embedded in the sheath 10, and the extension direction of the side wall of the tear groove U intersects with the optical unit 20. The extension direction of the groove wall (i.e., the side wall) of the tear groove U can roughly determine the tearing trend, direction, and tearing path when the sheath 10 is torn. By setting the extension direction of the side wall of the tear groove U to intersect with the optical unit 20, when the sheath 10 is torn through the tear groove U, the tearing path can pass through the optical unit 20, thereby ensuring that the optical fiber 21 can be exposed.

[0078] For example, in other embodiments, the extension direction of the side wall of the partial tearing groove U may also intersect with the electrical unit 30, so that when the sheath 10 is torn through the tearing groove U, the tearing path may pass through the electrical unit 30, thereby ensuring that the wire 31 can be exposed.

[0079] See Figure 2 and Figure 3 , the optical unit 20 includes an optical fiber 21 .

[0080] Optical fiber 21, the primary component of optical fiber cable 100, is used to transmit optical signals. For example, after optical fiber cable 100 is connected to a user's home optical network unit (ONU) and a room-level information box (i.e., a miniaturized optical line terminal (OLT)), optical fiber 21 within optical fiber cable 100 transmits signals between the main optical modem and the room-level information box.

[0081] See Figure 2 and Figure 3 , each optical fiber 21 extends along the first direction X.

[0082] Among them, see Figure 2 and Figure 3 The first direction X is the length extension direction of the optical / electrical composite cable 100 .

[0083] Figure 2 and Figure 3 The second direction Y in the diagram may be the arrangement direction of the optical unit 20 and the electrical unit 30. The second direction Y intersects the first direction X. For example, the first direction X and the second direction Y are perpendicular to each other. It is understood that the dimension of the optoelectronic composite cable 100 in the second direction Y may be regarded as the width of the optoelectronic composite cable 100.

[0084] See Figure 2 and Figure 3 The third direction Z may be a thickness direction of the optical / electrical composite cable 100 . For example, the third direction Z may intersect with the first direction X and the second direction Y. For example, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0085] For example, see Figure 2 and Figure 3 The optical unit 20 may include one optical fiber 21 , or in other embodiments, the optical unit 20 may include multiple optical fibers 21 .

[0086] See Figure 2 and Figure 3 The electrical unit 30 is embedded in the sheath 10 . The electrical unit 30 is used to realize the transmission of electrical signals in the optical-electrical composite cable 100 .

[0087] See Figure 2 and Figure 3 The electrical unit 30 and the optical unit 20 are spaced apart, and the extension direction of the electrical unit 30 is the same as the extension direction of the optical unit 20 , thereby avoiding mutual interference between the electrical unit 30 and the optical unit 20 .

[0088] See Figure 2 and Figure 3 , the electrical unit 30 includes a conductive wire 31 and a first fiber yarn 32 .

[0089] The wire 31 is a core component of the electrical unit 30 and is used to transmit electrical signals.

[0090] Exemplarily, the wire 31 may be made of any material capable of transmitting electrical signals. For example, the material of the wire 31 may include metals such as copper, silver, aluminum, gold, or alloys thereof.

[0091] The first fiber yarn 32 does not need to be conductive, and has certain toughness and strength.

[0092] See Figure 2 and Figure 3The conductive wire 31 and the first fiber yarn 32 are in contact with each other. For example, the peripheral surface of the conductive wire 31 and the first fiber yarn 32 are arranged in contact with each other.

[0093] When the optoelectronic composite cable 100 is subjected to stress, the wire 31 in the electrical unit 30 is easily deformed or broken after being subjected to tension, resulting in failure in the electrical signal transmission of the optoelectronic composite cable 100. Especially when the wire 31 is made of copper material, the copper wire 31 with weak tensile strength is easy to become thinner or even break after being subjected to tension, and the resistance in the thinned wire 31 increases, which also affects the conductive performance of the optoelectronic composite cable 100.

[0094] In the optoelectronic composite cable 100 provided in the embodiment of the present application, by arranging the first fiber yarn 32 in the electrical unit 30, a certain tensile strength can be provided by the first fiber yarn 32 when the electrical unit 30 is subjected to stress (such as tension), thereby sharing the stress on the conductor 31, reducing the probability of deformation of the conductor 31 due to excessive stress burden, improving the tensile strength of the electrical unit 30 and even the entire optoelectronic composite cable 100, optimizing the electrical performance of the optoelectronic composite cable 100, and improving the service life of the optoelectronic composite cable 100.

[0095] In addition, as the tensile strength of the entire optoelectronic composite cable 100 increases, the probability of fiber breakage of the optical fiber 21, another key component in the optoelectronic composite cable 100, is also reduced, thereby optimizing the optical transmission performance of the optoelectronic composite cable 100.

[0096] In some embodiments, the connector 200 is connected to the optical fiber 21 and the wire 31 in the optical-electrical composite cable 100 , thereby achieving optical communication of the optical-electrical composite cable 100 and external connection of electrical signals.

[0097] In some embodiments, the connector 200 is also connected to the first fiber yarn 32 in the optoelectronic composite cable 100 , thereby improving the connection strength between the optoelectronic composite cable 100 and the connector 200 through the first fiber yarn 32 and improving the service life of the composite cable assembly 300 .

[0098] Figure 4 is an enlarged view of a cross section of the electrical unit 30 perpendicular to the first direction X, Figure 5 It is a structural three-dimensional diagram of the electrical unit 30.

[0099] In some embodiments, see Figure 4 and Figure 5 The electrical unit 30 includes a plurality of conductors 31 , which are arranged in parallel, and the first fiber yarn 32 is arranged in the gaps enclosed by the plurality of conductors 31 .

[0100] For example, the first fiber yarn 32 can also extend roughly along the first direction X, so that the first fiber yarn 32 can be correspondingly arranged at any position of the multiple wires 31 in the first direction X, so that the electrical unit 30 and even the optoelectronic composite cable 100 can have good tensile strength at any position in the first direction X.

[0101] In addition, the first fiber yarn 32 is arranged in the gap surrounded by multiple conductors 31, which can maximize the utilization of the design space and reduce the design space occupied by the first fiber yarn 32 without affecting the miniaturized design of the optoelectronic composite cable 100.

[0102] Figure 6 It is another structural perspective view of the electrical unit 30 .

[0103] In some embodiments, see Figure 6 , the conductor 31 is twisted with the first fiber yarn 32.

[0104] For example, see Figure 6 The conductor 31 is arranged in a spiral roughly around the center line of the sheath 10, and the first fiber yarn 32 is twisted together with the spiral conductor 31 and is also arranged in a spiral, so that the first fiber yarn 32 is in close contact with the conductor 31. When the electrical unit 30 is subjected to stress, the first fiber yarn 32 can respond in the first time and play a tensile effect, further reducing the probability of the conductor 31 being broken due to stress or the size being reduced, resulting in excessive resistance and short circuit or open circuit.

[0105] It should be noted that, in order to illustrate the twisting trend of the conductor 31 and the first fiber yarn 32, Figure 6 The size of the first fiber yarn 32 is magnified in FIG. 3 . It can be understood that the fibers included in the first fiber yarn 32 are slender and small in size. Figure 6 In the embodiment, the first fiber yarn 32 can be multiple, and the conductor 31 can also be multiple, Figure 6 Only one wire 31 is used as an example for schematic description.

[0106] Figure 7 is another enlarged view of a cross section of the electrical unit 30 perpendicular to the first direction X,

[0107] In some embodiments, see Figure 7 , the first fiber yarn 32 is also arranged around the conductive wire 31 .

[0108] For example, the first fiber yarn 32 may be sheathed on the circumference of the plurality of conductive wires 31 .

[0109] Or for example, in Figure 5 and Figure 6 On the basis of this, part of the first fiber yarn 32 is sleeved on the circumference of the plurality of conductive wires 31 .

[0110] By arranging the first fiber yarn 32 around the conductor 31 , the conductor 31 can also be protected, the tensile strength of the electrical unit 30 and even the optoelectronic composite cable 100 can be improved, and the performance of the optoelectronic composite cable 100 can be optimized.

[0111] Figure 8 FIG. 1 is another cross-sectional view perpendicular to the first direction X of the optoelectronic composite cable 100 .

[0112] In some embodiments, see Figure 3 The optical unit 20 may be a bare fiber structure, that is, the optical unit 20 may only include the key structure optical fiber 21.

[0113] Or in some embodiments, see Figure 8 The optical unit 20 further includes a second fiber yarn 22 , which is arranged around the optical fiber 21 .

[0114] By arranging a second fiber yarn 22 around the outer periphery of the optical fiber 21, the overall tensile strength of the optoelectronic composite cable 100 can be further improved, while further improving the protection of the critical and relatively fragile structural optical fiber 21, further reducing the probability of the optical fiber 21 breaking problem, and improving the service life of the optoelectronic composite cable 100.

[0115] Or in other embodiments, the optical unit 20 also includes other structures. For example, the optical unit 20 as a whole can be a loose tube structure, that is, the optical unit 20 not only includes the optical fiber 21, but also includes a fiber grease and a loose tube arranged around the optical fiber 21 in sequence, wherein there is a gap between the loose tube and the optical fiber 21, and the fiber grease is filled in the gap.

[0116] The optical fiber 21 is extremely sensitive to water vapor. On the one hand, water vapor can easily cause cracks on the surface of the optical fiber 21 to expand, thereby damaging the strength of the optical fiber 21. On the other hand, water vapor can chemically react with the optical fiber 21, resulting in a large loss of the optical fiber 21, affecting the communication quality of the optoelectronic composite cable 100.

[0117] The fiber paste has waterproof and moisture-proof properties, thereby protecting the optical fiber 21 from water vapor and moisture, extending the service life of the optoelectronic composite cable 100, and optimizing the communication quality of the optoelectronic composite cable 100.

[0118] For example, the material of the fiber paste may include oil, inorganic filler, thickener or antioxidant.

[0119] The loose tube plays a role of mechanical buffering, and together with the fiber paste, it protects the optical fiber 21 to prevent the optical fiber 21 from being broken or damaged due to stress inside or outside the optoelectronic composite cable 100.

[0120] For example, the material of the loose tube may include polybutylene terephthalate (PBT), polypropylene (PP), polycarbonate (PC), and the like.

[0121] Exemplarily, the loose tube may include a multi-layer structure, wherein the multi-layer structures are nested together. Exemplarily, the materials of the multi-layer structure of the loose tube may be different from each other.

[0122] For example, the stiffness of the sheath 10 may be greater than that of the loose tube, and the toughness of the loose tube may be stronger than that of the sheath 10 .

[0123] In some embodiments, see Figure 3 The diameter of the electrical unit 30 can be larger than the diameter of the optical unit 20, that is, the electrical unit 30 is thicker than the optical unit 20, so that in the process of the optoelectronic composite cable 100 being subjected to force, such as the process of being subjected to tension, the electrical unit 30 can be subjected to force first. For example, the first fiber yarn 32 in the electrical unit 30 can be subjected to force first, thereby effectively reducing the stress (such as tension) on the optical unit 20, thereby avoiding damage to the key and relatively fragile structural optical fiber 21 in the optical unit 20, thereby extending the service life of the optoelectronic composite cable 100.

[0124] In some embodiments, the diameter of each wire 31 is 0.14 mm to 0.18 mm.

[0125] For example, the diameter of each wire 31 may be 0.14 mm, 0.157 mm, 0.16 mm, 0.1725 mm, or 0.18 mm.

[0126] For example, the electrical unit 30 may include seven wires 31 with a diameter of 0.16 mm, or the electrical unit 30 may include more or fewer wires 31 .

[0127] In the embodiment of the present application, a first fiber yarn 32 is provided in the electrical unit 30, and a part of the stress on the conductor 31 is shared by the first fiber yarn 32, so that while ensuring that the electrical unit 30 as a whole has sufficient tensile strength, the stress burden that the conductor 31 needs to bear is reduced, thereby providing space for reducing the diameter of the conductor 31. For example, the diameter of each conductor 31 can be reduced to 0.14mm~0.18mm, thereby reducing the consumables of the conductor 31 and reducing the preparation cost of the optoelectronic composite cable 100.

[0128] In some embodiments, the material of the first fiber yarns 32 and the second fiber yarns 22 includes one or more of aramid, carbon fiber, and glass yarn.

[0129] That is, the first fiber yarn 32 and the second fiber yarn 22 may be made of fiber material.

[0130] For example, the material of the first fiber yarns 32 and / or the second fiber yarns 22 may include only glass yarns, thereby reducing the manufacturing cost of the optoelectronic composite cable 100 .

[0131] Alternatively, for example, the material of the first fiber yarns 32 and / or the second fiber yarns 22 may include only aramid, thereby increasing the strength of the electrical unit 30 and / or the optical unit 20 and improving the tensile strength of the optoelectronic composite cable 100 .

[0132] Alternatively, for example, the material of the first fiber yarn 32 and / or the second fiber yarn 22 may include a mixture of glass yarn and aramid, thereby taking into account both the production cost and the tensile strength of the optoelectronic composite cable 100 .

[0133] For example, the material of the first fiber yarn 32 and / or the second fiber yarn 22 may also be a fiber-reinforced composite material.

[0134] In some embodiments, see Figure 2 、 Figure 3 、 Figure 8 and Figure 9 The optical-electrical composite cable 100 further includes two electrical units 30 and an electrode identification structure P.

[0135] Among them, see Figure 2 、 Figure 3 、 Figure 8 and Figure 9 The two electrical units 30 are respectively arranged on both sides of the optical unit 20 and serve as two electrodes of the optoelectronic composite cable 100 for transmitting different electrical signals, for example, Figure 3 The wire 31 in the electrical unit 30 on the left side is used to transmit positive electrical signals. Figure 3 The wire 31 in the electrical unit 30 on the middle right is used to transmit a negative electrical signal.

[0136] See Figure 2 、 Figure 3 、 Figure 8 and Figure 9 The electrode identification structure P can be provided in two electrical units 30 , with one electrical unit 30 on a side away from the other electrical unit 30 , so that the distances between the electrode identification structure P and the two electrical units 30 are different, thereby distinguishing the two electrical units 30 .

[0137] The electrode identification structure P is used to distinguish the polarity of the wires 31 in the two electrical units 30, for example, see Figure 3The electric unit 30 closer to the electrode identification structure P (the electric unit 30 on the left) can transmit a positive signal, and the electric unit 30 farther from the electrode identification structure P (the electric unit 30 on the right) can transmit a negative signal.

[0138] Exemplarily, the electrode identification structure P can be a color bar, or it can also be a groove on the surface of the sheath 10 of the optoelectronic composite cable 100, etc. Any structure that can distinguish between two electrical units 30 can be used as the electrode identification structure P, and the embodiments of the present application do not limit this.

[0139] Exemplarily, the electrode identification structure P can also extend along the first direction X, thereby ensuring that the electrode identification structure P is correspondingly provided at each position of the electrical unit 30 in the first direction X, thereby ensuring that any position of the optoelectronic composite cable 100 can be cut off and used as a connection position.

[0140] In some embodiments, the material of the sheath 10 may include one or more of thermoplastic polyurethane (TPU), polyvinyl chloride (PVC), polydimethylsiloxane (PDMS), polycarbonate (PC), polyethersulfone (PES), polyphenylene sulfone resins (PPSU), fluorinated ethylene propylene (FEP), polyamide (PA), and fluoroplastics.

[0141] Exemplarily, the sheath 10 can be made of a transparent material. While ensuring that the sheath 10 can protect the optical unit 20 from external damage, the sheath 10 made of the transparent material can also improve the aesthetics of the optoelectronic composite cable 100. For example, when the optoelectronic composite cable 100 is placed in an indoor scene, it is beneficial to reduce the visibility of the optoelectronic composite cable 100, improve the overall aesthetics of the room, and reduce damage to the overall coordination of the interior decoration.

[0142] For example, in other embodiments, the material of the sheath 10 may be opaque. For example, the optoelectronic composite cable 100 may be wiring. For example, the material of the sheath 10 in the optoelectronic composite cable 100 may include low smoke zero halogen (LSZH) material.

[0143] Figure 9 FIG. 1 is another cross-sectional view perpendicular to the first direction X of the optoelectronic composite cable 100 .

[0144] In some embodiments, see Figure 9 The optical-electrical composite cable 100 further includes a strength member 40 .

[0145] See Figure 9 The reinforcement member 40 is filled in the sheath 10 and is used to enhance the strength of the optoelectronic composite cable 100. For example, it can enhance the tensile strength of the optoelectronic composite cable 100, and prevent the optoelectronic composite cable 100 from bending or stretching during construction, which may cause the key components, the optical fiber 21 and the conductor 31, to break, affecting the performance and service life of the optoelectronic composite cable 100.

[0146] See Figure 9 The extension direction of the reinforcement member 40 is the same as the extension direction of the optical fiber 21, that is, the length extension direction of both is the first direction X, so that a reinforcement member 40 is correspondingly provided at any position along the length direction of the optical fiber 21, thereby forming complete protection for the optical fiber 21, and the same applies to the wire 31.

[0147] See Figure 9 The reinforcement member 40 is spaced apart from the optical unit 20, and the reinforcement member 40 is also spaced apart from the electrical unit 30, so that while the reinforcement member 40 protects the optical fiber 21 and the wire 31, it prevents the reinforcement member 40 from contacting the optical fiber 21 and the wire 31, causing an impact on the transmission of the optical fiber 21 and the wire 31, for example, causing signal leakage or signal contamination of the optical fiber 21, or, for example, causing a short circuit in the wire 31.

[0148] Exemplarily, the material of the reinforcement 40 may include thin steel wire, copper wire, aluminum wire, galvanized steel, stainless steel, copper-plated steel or nickel-plated steel, or the reinforcement 40 may also include fiber reinforced polymer (FRP), polycarbonate (PC) or fluoroplastic and other materials with a certain strength.

[0149] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in this disclosure should be included within the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
