Abstract
The utility model discloses an optical fiber composite variable-frequency cable including a cable core. The cable core is formed by stranding a plurality of power line cores and an optical fiber unit and is wrapped with an outer sheath in an extruded mode; and each power line core is composed of a conductor, an insulating layer wrapping the conductor in an extruded mode and a shielding layer wrapping outside the insulating layer in an extruded mode. Because the optical fiber unit is adopted for replacing a copper wire core in the prior art to transmit signals, it is guaranteed that the signals are not interfered by frequency fluctuation of the cable during the transmission; accordingly, signal transmission stability is improved, and signal transmission quantity is increased.
Description
Technical field
The utility model relates to a kind of cable, the compound frequency conversion cable of especially a kind of optical fiber.
Background technology
Along with frequency conversion equipment is constantly to high-tech, high-performance future development, its complicated function to its with it matching used cable higher requirement has been proposed, except meeting normal transmission of electricity requires, also should meet the requirement of its signal transmission.In existing frequency-changing cable, signal transmssion line core mostly is copper wire structure.Frequency-changing cable use procedure medium frequency can constantly change at low frequency, intermediate frequency, high frequency at any time because operating mode is different, and frequency fluctuation value is conventionally larger, and copper wire signal transmssion line core is just easily subject to the interference of frequency fluctuation, affects the stability of signal transmission.In addition, the transmission quantity of copper wire core is also relatively little.
Utility model content
The utility model is to provide a kind of optical fiber compound frequency conversion cable, to solve frequency-changing cable signal in prior art, transmits the technical problem that interference, stable signal transmission are poor and transmission quantity is relatively little that is easily subject to frequency fluctuation.
For solving above technical problem, the compound frequency conversion cable of optical fiber described in the utility model, comprises cable core, and described cable core is by some power cores and fiber unit is stranded forms, and cable core extrudes oversheath outward; Described power core by conductor, be extruded in the insulating barrier outside conductor and the screen that is extruded in outside insulating barrier forms.
Described power core by conductor, be extruded in the insulating barrier outside conductor and the screen that is extruded in outside insulating barrier forms.
The utility model beneficial effect is: adopt fiber unit to replace copper wire core in prior art to carry out signal transmission, guarantee that signal is not subject to the interference of cable frequency fluctuation in transmitting procedure, thereby improve the stability of signal transmission and the transmission quantity of signal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1:
As shown in Figure 1, the compound frequency conversion cable of optical fiber described in the utility model, comprises by fiber unit 4 and the three power cores that are positioned at cable center and adopts the stranded cable core forming of 1+3 structure, cable core extrudes sheath 5 outward; Outside tinned copper conductor 1, extrude low dielectric loss insulating barrier 2, then form power core at low dielectric loss insulating barrier 2 braiding shielding layer of copper wires.
Embodiment 2:
As shown in Figure 2, be with embodiment difference, fiber unit 4 residing position in cable core is different, in cable core edge.
Above-mentioned is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement and adjustment, these improvement and adjustment also should be considered as protection range of the present utility model.
