Abstract

The utility model discloses an environment-friendly monitoring telephone network cable assembly, which relates to a signal transmission cable. The cable assembly comprises a radio frequency signal cable; an insulating material layer, a shielding layer and a sheath wrap a cable core orderly from the inside out to form the radio frequency signal cable; the radio frequency signal cable is also provided with a telephone cable, which is a multi-core cable; and the sheath wrapping the telephone cable is integrated with the sheath. Since the radio frequency signal cable is integrated with the telephone cable, when the cable assembly needs to be laid, only one pipeline needs to be buried, only one cable needs to be threaded, consequently, workload can be greatly reduced, and laying efficiency can be greatly increased. Moreover, the cable assembly can be formed and drawn out on equipment in one step, the sheaths of the whole cable assembly are integrated, the mutual connection is tight and firm, and therefore the production cost can be reduced, so the cable assembly has a wide market prospect.

Description

Environment-friendly monitoring telephone network bonding wire

Technical field

The utility model relates to a kind of signal transmssion line, is specially the environment-friendly monitoring telephone network bonding wire that is used for telephone.

Background technology

Along with economy, fast development of society, use sub-district, the office block of monitoring phone more and more, in the telecommunication network and video signal system that prevails in urban construction or transformation, rf signal line just is used for transmission video signal at present, telephone wire can only be used to receive calls function singleness; Rf signal line and telephone wire normally lay separately respectively, and not only the cable acquisition expenses is big, and the operation of laying cable is many, the time is long, and operating expenses is also big, cause the cost of engineering to improve; And surface is adopted in construction mostly, has influenced the clean and tidy of the appearance of the city.

The utility model content

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of environment-friendly monitoring telephone network bonding wire is provided, and this combination cable should have the characteristics of transmission video signal, telephone wire simultaneously, and production cost is lower.

The technical solution adopted in the utility model is: environment-friendly monitoring telephone network bonding wire, comprise rf signal line, this rf signal line is with one heart coated from inside to outside successively insulation material layer, screen and foreskin in the core periphery, it is characterized in that also being provided with on this rf signal line a telephone wire, described telephone wire is a split conductor, and outer coated crust and the described foreskin of telephone wire is connected as a single entity.

Described telephone wire and rf signal line are arranged in parallel side by side.

The environment-friendly monitoring telephone network bonding wire that the utility model provides fuses rf signal line, these two holding wires of telephone wire, only need bury a pipeline underground when mounted, wears single line; Thereby workload reduces greatly, and installment work efficient significantly improves.In addition, this combine rope can be on equipment once the property moulding pull out, the foreskin of whole cable forms an integral body, interconnects close and firm, production cost is also descended; Thereby has a vast market prospect.

Description of drawings

Fig. 1 is a perspective view of the present utility model.

Among the figure: 1-core, 2-insulation material layer, 3-screen, 4-foreskin, 5-rf signal line, 6-telephone wire, 7-crust.

Embodiment

As seen from the figure: this environment-friendly monitoring telephone network bonding wire, comprise rf signal line 5, this rf signal line 5 is identical with the structure of existing conventional rf signal line, is coated with one heart successively from inside to outside insulation material layer 2, screen 3 (generally adopting aluminium foil to add woven wire) and foreskin 4 in the periphery of core (generally being copper core) 1; Also be provided with a telephone wire 6 on the described rf signal line 5, described telephone wire 6 (shows it is quad for the split conductor of buyable among the figure; Also can be six heart yearns or eight heart yearns), coatedly be connected as a single entity at outer field crust of telephone wire 7 and described foreskin 4.This telephone wire 6 is arranged in parallel side by side with rf signal line 5; Generally speaking, the axial line of two lines preferably is in same plane.

Foreskin in the utility model and crust are the homogeneity insulating material (being generally the PVC plastics) that fuses; Extrusion molding together on same equipment, thus parallel arranged is together; Production equipment needs in addition simple refit, and those skilled in the art can be competent at repacking work.

Claims (2)

1, environment-friendly monitoring telephone network bonding wire, comprise rf signal line (5), this rf signal line (5) is with one heart coated from inside to outside successively insulation material layer (2), screen (3) and foreskin (4) in core (1) periphery, it is characterized in that on this rf signal line (5) telephone wire being set also, described telephone wire (6) is a split conductor, and the outer coated crust (7) of telephone wire is connected as a single entity with described foreskin (4).

2, environment-friendly monitoring telephone network bonding wire according to claim 1 is characterized in that this telephone wire (6) and described rf signal line (5) are arranged in parallel side by side.
