Abstract

The utility model relates to a concentric RF photoelectrical cable which has a multilayer structure. The concentric RF photoelectrical cable is characterized in that the multilayer structure includes an external housing layer, an external conductor layer, an insulating layer, an internal conductor layer, a plastic cushion layer and a sleeve from the outside to the inside; the external conductor copper tube layer is provided with embossing or a regular groove; optical fibers are arranged in the sleeve, optical fiber ointment is coated around each optical fiber and filled in the whole sleeve. The utility model has the advantages of double-transmission function, construction simplifying and cost saving.

Description

Concentric type radio frequency optoelectrical cable

Technical field:

The utility model relates to a kind of cable, and particularly a kind of concentric type radio frequency optoelectrical cable belongs to field of communication transmission.

Background technology:

At present, the communications line that we use all is a simple function, can only transmission of electric signals or light signal in same structure, the transmission line of this simple function is made of three parts, from inside to outside is followed successively by low density polyethylene (LDPE) endodermis, intermediate gas physical blowing layer, outsidely is the high density polyethylene (HDPE) exodermis, and such transmission line can't realize that photosignal transmits simultaneously, need many merchandisers of frame line just can transmit, so not only increased the expense of engineering, it is complicated also will to construct, and has strengthened manpower.

Summary of the invention:

The purpose of this utility model is in order to overcome above deficiency, a kind of concentric type radio frequency optoelectrical cable that has the duplicate transmissions function, saves cost to be provided.

The purpose of this utility model is achieved through the following technical solutions, a kind of concentric type radio frequency optoelectrical cable, be sandwich construction, ecto-entad is provided with external sheath layer, outer conductor layer, insulating barrier, inner conductor layer, plastic layer, sleeve pipe successively, conductor copper pipe layer is provided with embossing or has regular groove outside, be provided with multifiber in the sleeve pipe, at the outer optical fiber ointment of having placed of described every optical fiber, and optical fiber ointment is filled full described sleeve pipe.

The utility model compared with prior art has the following advantages: the dual-use function by the single comprehensive cable realization signal of telecommunication and optical signal transmission, made things convenient for application, and simplified construction, save manpower, reduced engineering cost.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Number in the figure: 1-external sheath layer, 2-outer conductor layer, 3-insulating barrier, 4-inner conductor layer, 5-plastic layer, 6-sleeve pipe, 7-optical fiber.

Embodiment:

In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection range.

Show the embodiment of the utility model concentric type radio frequency optoelectrical cable as Fig. 1, be sandwich construction, ecto-entad is provided with external sheath layer 1, outer conductor layer 2, insulating barrier 3, inner conductor layer 4, plastic layer 5, sleeve pipe 6 successively, insulating barrier 3 is the physical blowing layer, makes insulation effect more like this, and inner conductor layer 4 is copper pipe or solid copper conductor, can play better conductive effect like this, sleeve pipe 6 can be suitable for doing ferrule usefulness for metal or nonmetallic material, is preferably stainless steel.Conductor copper pipe layer 3 is provided with embossing or has regular groove outside, increase frictional force and use as leaky cable, be provided with optical fiber 7 in the rust steel pipe 6, at the outer optical fiber ointment of having placed of described every optical fiber 7, and the full described sleeve pipe 6 of optical fiber ointment filling, optical fiber ointment can play waterproof effect, so just can be so that optical communication and telecommunication transmit simultaneously, both make things convenient for application, also simplified construction, saved the expense of engineering.
