Description
Technical Field
The invention relates to the technical field of radio frequency coaxial cables, in particular to a photoelectric hybrid radio frequency coaxial cable which is simple in structure and convenient to use.
Background
Coaxial Cable (Coaxial Cable) refers to a Cable having two concentric conductors, with the conductors and shield sharing the same axis. The most common coaxial cable consists of a copper wire conductor insulated by an insulating material, outside of which is another layer of annular conductor and its insulator, and then the entire cable is encased by a jacket of polyvinyl chloride or teflon material.
When the system signal is transmitted and the connection is controlled, two kinds of cables, namely a radio frequency coaxial cable and an optical fiber are often used, and in order to ensure the coaxial characteristic of the radio frequency coaxial cable, the optical fiber is mostly independent of the radio frequency coaxial cable. However, if this is set up, there are the following problems:
① The optical fiber itself needs a sheath, which increases the occupied area and the cost;
② The radio frequency coaxial cable and the optical fiber are respectively paved, and the engineering is long in time consumption;
③ The system integration is not facilitated, and the cost of separate management and maintenance is higher.
The present invention thus provides a new radio frequency coaxial cable to solve the above problems.

Detailed Description
The present invention will be described in further detail with reference to specific examples.
As shown in fig. 1, the photoelectric hybrid radio frequency coaxial cable comprises an inner conductor 1, a dielectric layer 2 sleeved outside the inner conductor 1, an outer conductor 3 sleeved outside the dielectric layer 2, an outer shielding layer 4 sleeved outside the outer conductor 3 and a sheath 5 sleeved outside the outer shielding layer 4; the inner conductor 1 and the outer conductor 3 are coaxially arranged; an optical fiber layer 6 is further arranged between the outer conductor 3 and the outer shielding layer 4, the optical fiber layer 6 comprises an optical fiber bearing layer 61 positioned on the inner side, an optical fiber protection layer 63 positioned on the outer side and an optical fiber wire 63 clamped between the optical fiber bearing layer 61 and the optical fiber protection layer 62, and the optical fiber bearing layer 61 is made of a flexible buffer material. The present invention does not destroy the basic structure of the coaxial cable, maintains the circular cable shape, and only provides the optical fiber layer 6 for routing the optical fiber line 63 at the periphery of the outer conductor 3. The fiber support layer 61 is relatively easy to deform and the density can be adjusted as required. The optical fiber protection layer 62 and the sheath 5 can be made of materials with better toughness, such as PTFE, and the like, so that the optical fiber wires 63 can be embedded in the optical fiber bearing layer 61 without obviously affecting the overall deformation of the cable. Thus, the electric signal and the optical signal can be transmitted through the cable, the system space is saved, the installation efficiency is improved, and the later maintenance is convenient.
The optical fiber wire 63 is combined with the optical fiber carrying layer 61 in an SZ twisting manner or a winding manner. The optical fiber 63 can follow deformation even when the whole cable is bent, and the optical fiber 63 can be prevented from being broken.
What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
