Embodiment 1

[0025] please see Figure 1 to Figure 3 , a photoelectric hybrid cable containing a coaxial electric unit, which is composed of a cable core, a shielding layer 12 covering the cable core, and an outer sheath 13 that is extruded and coated outside the shielding layer. Layer and the outer layer of the cable core located outside the inner layer of the cable core; it is characterized in that the inner layer of the cable core is composed of a central reinforcement 9, four inner coaxial electrical units distributed along the outer edge of the reinforcement and a The filling rope 10 in the outer gap of the adjacent inner layer coaxial electric unit is formed, and each inner layer coaxial electric unit is composed of an inner conductor 4, an insulating layer 5 covering the inner conductor, and an outer layer outside the insulating layer. Conductor 6, insulating tape 7 located outside the outer conductor, and inner sheath 8 coated outside the insulating tape by extrusion molding. On t...

Embodiment 2

[0062] please see Figure 4 , and refer to Figure 1 to Figure 3 , the optical-electrical hybrid cable containing the coaxial electric unit is basically the same as the implementation example 1, the difference is that the solid filling strip can be other multiple; it can also be one; it can also be like Figure 4 Also has a small solid filler strip to round out the outer layer of the cable core.

[0063] Figure 4 The medium and small solid filling strips are located next to the ground wire and in the middle of the two solid filling strips 2 .

[0064] In the present invention, the coaxial power line unit and the optical cable unit are organically twisted into a cable core, the cable core is covered with a metal shielding tape, and a layer of plastic sheath is extruded outside the tape; it is a 4G base station signal transmission system. The processing unit BBU (BasedBandUnit) is ideal for transmitting optical signals and providing power supply cables for the remote radio u...

Abstract

The invention belongs to the technical field of cables and particularly relates to a photoelectric composite cable comprising coaxial electrical units. The photoelectric composite cable is composed of a cable core, a shielding layer and an outer sheath, wherein the shielding layer is wrapped outside the cable core, and the outer sheath is wrapped outside the shielding layer in an extrusion molding mode. The cable core is composed of a cable core inner layer and a cable core outer layer located outside the cable core inner layer. The photoelectric composite cable is characterized in that the cable core inner layer is composed of a reinforcer, the inner-layer coaxial electrical units and filling ropes, wherein the reinforcer is located at the center of the cable core inner layer, the inner-layer coaxial electrical units are distributed along the outer edge of the reinforcer, and the filling ropes are located at outer gaps between the adjacent inner-layer coaxial electrical units; the cable core outer layer is composed of the outer-layer coaxial electrical units, a plurality of optical cable units, a plurality of solid filling strips, a ground lead and tearing ropes. The invention further discloses a manufacturing method of the photoelectric composite cable. The photoelectric composite cable has the main advantages of being wider in purpose, better in shielding performance, more excellent in mechanical performance, smaller in diameter, lower in cost and easier to construct, and the manufacturing method is simple.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a photoelectric hybrid cable containing a coaxial electrical unit and a manufacturing method thereof. Background technique [0002] With the rapid development of the communication industry, the application of optical-electrical hybrid cables is increasing, and a lot of research and development has been carried out on optical-electrical hybrid cables at home and abroad. [0003] For example, the Chinese patent titled: A high tensile and flame retardant photoelectric composite cable, and the application number is: CN201310323268.4 discloses a high tensile and flame retardant photoelectric composite cable, which includes an optical cable unit 1, a cable unit 2, a tensile The cable 3, the tape 4 and the flame-retardant outer sheath 6, the cable unit 2 and the tensile cable 3 are surrounded on the outside of the optical cable unit 1, and the outside of the cable unit 2 and the tensile ...
