CN201315171Y - Composite cable for communication - Google Patents

Abstract

The utility model discloses a composite cable for communication, which comprises a signal line, a group of signal lines and two groups of data transmission lines, a group of power lines, a wrapping film and an outer sheath. An insulating layer is arranged outside a line core; and a shielding layer is arranged outside the insulating layer, thereby achieving the technical functions that not only can electric energy be transmitted, but also high-frequency data signal lines and low-frequency data signal lines can be transmitted without interference.

Description

The communication composite cable

Technical field

The utility model relates to a kind of communication composite cable.

Background technology

At present, all integrated in all kinds of Small-size Integrated Access Device in the communications field and mobile communications network in pursuit, just data line, holding wire, power line are integrated in the cable, customer requirements not only will reduce to lay the space, and also requirement will be eliminated interference problem each other.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of can transmission of electric energy again can carry high frequency data-signal and low frequency signal, and non-interfering communication composite cable.

In order to address the above problem, the utility model by the following technical solutions:

A kind of composite cable of using is characterized in that: include a holding wire, one group of holding wire, two groups of data lines, one group of power line, wrapped film, oversheath:

(1), a described holding wire comprises the single line core conductor, this core conductor skin is an insulation material layer, the outside screen that weaves for silver-gilt copper wire of this insulation material layer;

(2), described two groups of data lines, every group comprises two core conductors, every core conductor skin is an insulation material layer, every group of insulation material layer is the screen of silver-gilt copper wire braiding outward;

(3), described one group of power line, comprise two core conductors, every core conductor skin is an insulation material layer, each insulation material layer is with the screen of silver-gilt copper wire braiding outward altogether;

(4), described one group of holding wire, comprise three core conductors, every core conductor skin is an insulation material layer, each insulation material layer is with the screen of silver-gilt copper wire braiding outward altogether;

A described holding wire is positioned at the center of cable, and stranded after one with described one group of holding wire, two groups of data lines, one group of power line, skin is surrounded with film, and film has oversheath outward.

The utility model has adopted different woven shields to eliminate the phase mutual interference respectively the power line of the high-frequency data transmission line of a holding wire, two groups of pair twists, one group of pair twist as required, three strands of one group of holding wire are twisted together with a holding wire, two groups of high-frequency data transmission lines, one group of holding wire the back together jointly, realize a cable can transmission of electric energy again can transmitting high-frequency signal and the needs of low frequency signal, structure distribution is reasonable and the construction of cable stable, soft, volume is again little and can eliminate the phase mutual interference.For guaranteeing that cable reduces relative displacement, mechanism stable, with a wrapped film of cable outer layer that twists together jointly, the wrapped thin-film material of cable outer layer is a nonwoven fabrics.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is done nearly detailed explanation of a step.

Fig. 1 is a structure chart of the present utility model.

Embodiment

The composite cable of using shown in Figure 1 comprises a holding wire, two groups of high-frequency data transmission lines, and one group of power line, one group of holding wire also comprises wrapped film 12 and oversheath 13.

Outside the holding wire conductor 1 is insulating barrier 2, is silver-gilt copper wire establishment screen 3 outside the insulating barrier 2; Two groups of high-frequency data transmission lines, every group comprises two core conductors 4, and every core conductor 4 skins are insulation material layer 5, and every group of high-frequency data transmission line insulating barrier 5 skins are silver-gilt copper wire woven shield 6; One group of power line comprises two core conductors 7, and every core conductor 7 skins are that 8, one groups of power line insulation material layers of insulation material layer, 8 skins are silver-gilt copper wire woven shield 9; One group of holding wire comprises three core conductors 10, and every core conductor 10 skins are insulation material layer 11, and conductor 1 is 0.35mm ², insulating barrier 2 materials are perfluoroethylene-propylene; Core conductor 4 is 0.2mm ², insulation material layer 5 materials are perfluoroethylene-propylene, conductor 7 is 0.5mm ², insulation material layer 8 materials are perfluoroethylene-propylene, conductor 10 is 0.35mm ²
