Description

Technical Field

[0001] The utility model relates to the technical field of multifunctional cables, in particular to a composite cable. Background Art

[0002] The normal operation of network services generally requires that devices solve two problems through cables: power supply for the device itself and data transmission. However, the installation environment of some devices is relatively complex. For example, wireless network hotspot devices, 5G small base stations, video surveillance cameras, etc., it is difficult to find suitable power sockets around their installation environment, and it is difficult to power the equipment. In such scenarios, it is often hoped that one cable can be used to solve the problems of device power supply and data transmission at the same time.

[0003] Optical-electric hybrid cable is a composite cable that combines optical cable and electrical cable, which includes optical cable, power cable and digital cable. Since optical transmission, digital signal transmission and power transmission are three different types of transmission methods, there will be no mutual interference during the transmission process. At the same time, it can solve the problem of equipment power consumption and signal transmission. It retains the characteristics of ordinary optical fiber cable and digital cable and can also meet the relevant standards of low-voltage power transmission cable. Optical-electric composite cable uses optical fiber to transmit data signals and copper wire to transmit power signals, taking the best of both worlds, which can complete high-speed data transmission and long-distance equipment power supply.

[0004] Generally, independent optical cables, power cables and digital cables are cylindrical in shape, that is, the cross-section is circular. When multiple types of cables are composited, it is difficult to form the overall shape into a regular cylinder. Therefore, it is necessary to fill materials in the outermost protective sheath of the composite cable. The composite cable of this structure has a large diameter, occupies a large space, and the filling materials will increase the overall cost. Utility Model Content

[0025] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] The embodiment of the utility model provides a composite cable, comprising a sheath, a first functional cable, a second functional cable and a power cord. The sheath is a covering structure of the composite cable, covering multiple cables to form an integral structure; in the sheath, the first functional cable, the second functional cable and the power cord are independently arranged, and their functions do not affect each other.

[0027] The structure of the composite cable provided by the embodiment of the utility model and the positional relationship between the various structures are described in detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 4As shown, in the embodiment of the utility model, the first functional cable 12 and the second functional cable 13 are arranged side by side and spaced apart in the sheath 11, and the power cord 14 is located in the space between the first functional cable 12 and the second functional cable 13; the sheath 11 covers the outside of the first functional cable 12, the second functional cable 13 and the power cord 14. In the sheath 11, the above arrangement makes the void ratio inside the sheath 11 lower, that is, the main void part is the space between the first functional cable 12 and the second functional cable 13, and the power cord 14 is further filled in the space part. Under the condition of meeting the power connection function of the composite cable 10, the structural arrangement inside the composite cable 10 can also be optimized.

[0029] Through the above arrangement, the composite cable 10 is flat in shape, for example, the cross-sectional shape of the sheath 11 is oval or waist-shaped. Compared with the existing composite cable 10, the composite cable 10 provided by the embodiment of the utility model does not need to be filled with materials that change the shape of the cable, which can save the cost of the part of the material, and can optimize the cable production steps, thereby improving the production efficiency of the composite cable 10; and the flat composite cable 10 is smaller in volume, and thus the composite cable 10 occupies less space, which can save storage, transportation and other costs.

[0030] Continue to refer Figures 1 to 4 As shown, in the embodiment of the utility model, the cross-sectional shapes of the first functional cable 12 and the second functional cable 13 are both circular; the two arc-shaped portions of the sheath 11 are respectively fitted with the first functional cable 12 or the second functional cable 13 on the same side. The flat composite cable 10 includes two arc-shaped portions, the curvature of the two arc-shaped portions is the same as the circular curvature of the functional cables on the same side, and they are closely fitted to each other (without gap), so that the internal structural layout of the composite cable 10 is more reasonable.

[0031] In the embodiment of the utility model, the cross-sectional shape of the first functional cable 12 and the second functional cable 13 is preferably circular, but may also be other shapes. For example, the cross-sectional shape of the first functional cable 12 and the second functional cable 13 is elliptical or a special shape tending to be circular, and the corresponding sheath 11 has the same arc shape as the first functional cable 12 and the second functional cable 13 on the same side, thereby forming a tight covering structure; or, for example, the cross-sectional shapes of the first functional cable 12 and the second functional cable 13 may be the same or different.

[0032] In the embodiment of the utility model, the first functional cable 12, the second functional cable 13 and the metal wire 141 can be arranged in a certain pattern in the sheath 11, so that the layout of the cables inside the sheath 11 is more reasonable. Among them, the power cord 14 includes a plurality of independent metal wires 141, and the plurality of metal wires 141 are arranged side by side between the first functional cable 12 and the second functional cable 13; and the plane where the centers of the plurality of metal wires 141 are located is perpendicular to the plane where the centers of the first functional cable 12 and the second functional cable 13 are located.

[0033] For example, the power line 14 includes two independent metal wires 141 ; the two metal wires 141 are symmetrically arranged with the plane where the centers of the first functional cable 12 and the second functional cable 13 are located as the center.

[0034] In the embodiment of the utility model, the first functional cable 12 includes a digital cable, and the second functional cable 13 includes an optical cable; reinforcing members are inserted into the digital cable and the optical cable along the length direction.

[0035] By providing a reinforcement member in the existing digital cable or optical cable, such as a central reinforcement member 132 or a filling rope 133, the hardness of the digital cable or optical cable can be increased. This structure can also increase the hardness of the composite cable 10. For example, Figures 1 to 4 As shown, the digital cable includes a cable conductor core 121 and a cable sheath 122 covering the cable conductor core 121 ; the optical cable includes an optical fiber core 131 , a central strength member 132 and a filling rope 133 .

[0036] Among them, the digital cable can choose whether to add a shielding function according to the use requirements, that is, the structure of the digital cable can also be: Figure 3 and Figure 4 As shown, the digital cable includes a cable conductor core 121 and a cable shielding layer 123 and a cable sheath 122 which are sequentially coated on the cable conductor core 121. The cable shielding layer 123 has a shielding function. For example, the material of the cable shielding layer 123 is an aluminum foil shielding tape. And, as Figure 2 and Figure 4 As shown, the optical cable can be provided with or without the metal composite tape 134 according to functional requirements.

[0037] In the embodiment of the utility model, the first functional cable 12 and the second functional cable 13 are not limited thereto, and other cables may be selected and used according to the functional requirements of the composite cable 10 .

[0038] The utility model provides a composite cable 10, in which a power line 14 is arranged between a first functional cable 12 and a second functional cable 13, and a sheath 11 is covered on the outside of the above structure, so that the composite cable 10 has a flat shape. Compared with the existing round composite cable 10, no material filling is required, the molding process of the composite cable 10 is optimized and the manufacturing cost is reduced, and the composite cable 10 has a smaller size, occupies less space, and is convenient for storage, transportation and construction.
