Embodiment 1

[0026] please see Figure 1 to Figure 3, an optical cable with 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 coated outside the shielding layer. The cable core is composed of the inner layer of the cable core 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 reinforcing member 9 located in the center, four inner layer coaxial electrical units distributed along the outer edge of the reinforcing member and located in the corresponding 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 conductor located outside the insulating layer 6. The insulating tape located outside t...

Embodiment 2

[0063] please see Figure 4 , and refer to Figure 1 to Figure 3 , the optical cable with the coaxial electric unit is basically the same as the embodiment 1, the difference is that the solid filling bar 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.

[0064] 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 .

[0065] 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 unit RRU (RemoteRadioUnit); it can also b...

Abstract

The invention belongs to the technical field of cables, and particularly relates to a photoelectric cable with coaxial electric units. The photoelectric cable comprises a cable core, a shielding layer for coating the cable core and an outer sheath arranged on the exterior of the shielding layer in an extruding and coating manner, wherein the cable layer comprises a cable core inner layer and a cable core outer layer positioned outside the cable core inner layer; the photoelectric cable is characterized in that the cable core inner layer comprises a reinforced layer positioned in the center, multiple inner layer coaxial electric units distributed along the outer edge of the reinforced part and filling ropes positioned in outer gaps of the adjacent inner layer coaxial electric units; and the cable core outer layer comprises multiple outer layer coaxial electric units, multiple optical cable units, multiple solid filling strips, a ground wire and tearing ropes. The invention discloses a manufacturing method for the photoelectric hybrid cable. The photoelectric cable has the main following beneficial effects of wider application, better shielding performance, better mechanical performance, smaller diameter, lower cost, easier construction and simple manufacturing method.

Description

[0001] This application is a divisional application for an invention patent titled: Optical-electrical hybrid cable with coaxial electric unit and its manufacturing method, application date: December 18, 2014, and application number: 201410785982.X. technical field [0002] The invention belongs to the technical field of cables, and in particular relates to an optical cable with a coaxial electric unit and a manufacturing method thereof. Background technique [0003] 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.
