Embodiment 1

[0025] see Figure 1 to Figure 3 , an optoelectronic hybrid cable containing a coaxial electrical 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 wrapped outside the shielding layer. It is characterized in that the inner layer of the cable core is composed of a central strength member 9, four inner layer coaxial electrical units distributed along the outer edge of the strength member, and The filling ropes 10 in the outer gaps of adjacent inner-layer coaxial electrical units are formed by filling ropes 10. Each inner-layer coaxial electrical unit consists of an inner conductor 4, an insulating layer 5 covering the inner conductor, and an outer layer located outside the insulating layer. The conductor 6, the insulating tape 7 outside the outer conductor, and the inner sheath 8 which is extruded and wrapped outside the insulating tape are formed. On the cross section of the plane perpendicular to...

Embodiment 2

[0062] see Figure 4 , and refer to Figure 1 to Figure 3 , the optoelectronic hybrid cable containing the coaxial electrical unit is basically the same as the implementation example 1, the difference is that the solid filler strip can be more than one; it can also be one; it can also be like Figure 4 It also has a small solid filler strip, which can make the outer layer of the cable core more rounded.

[0063] Figure 4 The small and medium solid filler bars are located next to the ground wire, in the middle of the two solid filler bars 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; The processing unit BBU (Based Band Unit) is also an ideal choice for transmitting optical signals and providing cables for power supply for the remote radio unit RRU (Remote Radio Unit); it c...

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.
