Description

Technical Field

[0001] This utility model relates to the field of optoelectronic hybrid cable technology, and in particular to optoelectronic hybrid cables. Background Technology

[0002] Hybrid fiber-optic cables integrate optical fibers and copper conductors into the same cable, which can solve the problems of data transmission and power supply to devices at the same time. Such hybrid cables can achieve efficient and stable data transmission and power supply in complex environments, such as complex installation scenarios of Wi-Fi access points, 5G small base stations, and video surveillance cameras.

[0003] For example, patent CN218768862U discloses a flexible optoelectronic hybrid cable for medical equipment, comprising a solid polyvinyl chloride (PVC) strip, with glass fiber units arranged opposite each other on the central axis of the PVC strip. Outside each glass fiber unit, from the inside out, are sequentially arranged a Teflon tape insulation layer, a braided layer, a paper tape layer, and an outer sheath layer. This optoelectronic hybrid cable not only has good attenuation performance and can achieve higher bandwidth, but it can also simultaneously support two devices, reducing the space occupied by the cable. However, in this optoelectronic hybrid cable, the optical fiber of the optical unit is sensitive to electromagnetic interference, while the power conductor of the electrical unit generates an electromagnetic field when energized, which may lead to increased fiber transmission loss and mutual interference between the optoelectronic units. To address these issues, innovative designs based on existing optoelectronic hybrid cables are urgently needed. Utility Model Content

[0004] This invention provides a hybrid optical-electric cable to solve the technical problem in existing hybrid optical-electric cables where the optical fiber of the optical unit is sensitive to electromagnetic interference, while the power supply wire of the electrical unit generates an electromagnetic field when energized, which may lead to increased optical fiber transmission loss and mutual interference between the optical and electrical units.

[0005] This utility model provides a hybrid optoelectronic cable, including an inner sheath and a set of optical fiber lines and multiple sets of power lines passing through the inner sheath. The optical fiber lines and multiple sets of power lines are circumferentially distributed in the inner sheath along the axial direction, and cable grease is filled between the optical fiber lines, power lines and the inner sheath. A reinforcing core is provided through the power line along the central axis direction, and a positioning component is provided outside the reinforcing core to limit the threading position of the optical fiber lines and power lines and reduce optoelectronic interference.

[0006] Preferably, the positioning component includes a buffer sleeve fitted over the reinforcing core, and an elastic separator sleeve is fitted over the outside of the buffer sleeve.

[0007] Preferably, the elastic partition sleeve has multiple limiting grooves at equal angles along the axial direction on its outer side; the optical fiber and power cord are circumferentially distributed on the outer side of the elastic partition sleeve, and the optical fiber and power cord are engaged and limited in the limiting grooves.

[0008] Preferably, the optical fiber includes multiple optical fiber cores, the outer surface of which is encapsulated with a metal layer, the space between the metal layer and the optical fiber core is filled with fiber grease, and a shielding layer is provided on the outer surface of the metal layer.

[0012] Preferably, the inner sheath is covered with a plastic steel strip, and the plastic steel strip is covered with an outer sheath.

[0013] The technical solution provided in this application embodiment may include the following beneficial effects: the optoelectronic hybrid cable can position and thread the optical fiber and power line in the inner sheath, and stably maintain the distribution distance between the optical fiber and the power line, increase the isolation gap, and avoid the problem of mutual interference between optoelectronic units.

[0014] Furthermore, the reinforcing core is equipped with positioning components on the outside to limit the threading positions of the optical fiber and power line and reduce photoelectric interference.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] It should also be understood that the terminology used in this utility model specification is merely for describing specific aspects of the present application. It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] like Figures 1 to 3 As shown, this application provides a hybrid optoelectronic cable, including an inner sheath 1 and a set of optical fiber lines 2 and multiple sets of power lines 3 passing through the inner sheath 1. The optical fiber lines 2 and multiple sets of power lines 3 are circumferentially distributed in the inner sheath 1 along the axial direction, and cable grease 4 is filled between the optical fiber lines 2, power lines 3 and the inner sheath 1. A reinforcing core 5 is provided through the power lines 3 along the central axis direction, and a positioning component is provided outside the reinforcing core 5 to limit the threading position of the optical fiber lines 2 and power lines 3 and reduce optoelectronic interference. A plastic steel tape 11 is sleeved on the outside of the inner sheath 1, and an outer sheath 12 is sleeved on the outside of the plastic steel tape 11.

[0030] Please see Figure 3 and Figure 4 The positioning component includes a buffer sleeve 6 sleeved outside the reinforcing core 5, and an elastic partition sleeve 7 sleeved outside the buffer sleeve 6. Multiple limiting grooves 8 are formed at equal angles along the axial direction on the outside of the elastic partition sleeve 7; the optical fiber 2 and the power cable 3 are circumferentially distributed outside the elastic partition sleeve 7, and the optical fiber 2 and the power cable 3 are engaged and limited in the limiting grooves 8.

[0031] Please see Figure 2 The optical fiber line 2 includes multiple optical fiber cores 21. The outer surface of the optical fiber cores 21 is encapsulated with a metal layer 22. Fiber grease 23 is filled between the metal layer 22 and the optical fiber cores 21. A shielding layer 24 is sleeved on the outside of the metal layer 22.

[0032] For example, when the fiber optic cable 2 and the power cable 3 are threaded into the inner sheath 1, the buffer sheath 6 and the elastic partition sleeve 7 outside the reinforcing core 5 can initially position them. The fiber optic cable 2 and the power cable 3 are engaged in the limiting groove 8 opened on the outside of the elastic partition sleeve 7, so that the fiber optic cable 2 and the power cable 3 are distributed circumferentially inside the inner sheath 1, maintaining the distance between the fiber optic cable 2 and the power cable 3, avoiding the problem of mutual interference between the photoelectric units caused by the two being too close. In addition, the fiber optic cable 2 and the power cable 3 are evenly distributed in the inner sheath 1 along the circumferential direction. Their uniform arrangement can maintain the roundness of the overall cable, so that the hybrid cable is subjected to uniform force when it is bent, thereby improving the service life of the hybrid cable.

[0033] It should be noted that the fiber core 21 of the optical fiber line 2 is covered with a metal layer 22 and a shielding layer 24, which can further reduce the electromagnetic interference generated by the power line 3, thereby reducing the optical fiber transmission loss.

[0034] Please see Figures 3-6 The fiber optic cable 2 is provided with a separator to further maintain the distance between it and the power cable 3. The separator includes a separator strip 9 symmetrically fixed to the outside of the fiber optic cable 2 along the central axis, with the end of the separator strip 9 away from the fiber optic cable 2 elastically supported on the outside of the power cable 3. Multiple slots 91 are evenly spaced on the outside of the separator strip 9, and lightweight insulating blocks 92 are engaged in the slots 91.

[0035] Separation strips 9 are fixed on both sides of the fiber optic cable 2 near the power lines 3. The separation strips 9 are elastically supported between the fiber optic cable 2 and the power lines 3 on both sides. They can stably maintain the distance between the fiber optic cable 2 and the power lines 3 on both sides, and prevent the cable from bending or deforming during the wiring process, which could cause local close contact. Lightweight insulating blocks 92 are installed at equal intervals on the outside of the separation strips 9. The lightweight insulating blocks 92 can increase the support strength of the separation strips 9 and prevent excessive deformation that would reduce the distance between the fiber optic cable 2 and the power lines 3. This increases the distance between the fiber optic cable 2 and the power lines 3 from the conventional 2-3mm to more than 5mm, reducing coupling capacitance and mutual inductance, thereby avoiding photoelectric interference between the mixed cables.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. 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, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
