Abstract
The utility model discloses a lightweight low-attenuation corrugated coaxial cable. The lightweight low-attenuation corrugated coaxial cable comprises an inner conductor and an outer aluminum conductor; an insulator is arranged between the inner conductor and the outer aluminum conductor; the outer aluminum conductor is sheathed with a sheath; the outer aluminum conductor is multi-connected ring-shaped; and the diameter of the outer aluminum conductor is 0.25cm. The lightweight low-attenuation corrugated coaxial cable of the utility model is advantageous in light weight, small transmission attenuation, small return loss, and convenient transportation and installation. An outer copper conductor is replaced by the outer aluminum conductor, and therefore, the weight of the cable is reduced, and at the same time, the outer conductor is multi-connected ring-shaped, and therefore, production can be facilitated, and qualified indicators can be ensured; and the diameter of the outer aluminum conductor is 0.25cm, and therefore, signal transmission blocking can be alleviated, and the dielectric constant of PE is changed, and transmission attenuation is smaller.
Description
Technical field
The utility model relates to a kind of coaxial cable.
Background technology
Coaxial cable signal transmission is mainly kelvin effect, and what lean on is that conductive surface carrys out signal transmission, and what under high-frequency, signal transmission was leaned on is inner wire outer surface and the outer conductor inner surface of coaxial cable.What present coaxial cable generally adopted is copper outer conductor, and the transmission attenuation of copper outer conductor is larger, and weight is large simultaneously, and cost is higher.
Utility model content
The purpose of this utility model is to provide the low decay corrugated coaxial cables of a kind of lightweight, its lighter weight, and transmission attenuation is less.
For reaching this object the utility model by the following technical solutions:
The low decay corrugated coaxial cables of a kind of lightweight, comprises inner wire, aluminium outer conductor, between inner wire and aluminium outer conductor, is provided with insulator, and on aluminium outer conductor, cover has sheath, described aluminium outer conductor to be multiple annulus connection shapes, and the diameter of aluminium outer conductor is 0.25cm.
Coaxial cable quality of the present utility model is light, and transmission attenuation is little, return loss is little, be convenient to transportation installs.Change copper outer conductor into aluminium outer conductor, alleviated the quality of cable, outer conductor is multiple annulus and connects shape simultaneously, can when producing, conveniently produce like this, can guarantee that again indices is qualified; The diameter of aluminium outer conductor is 0.25cm, reduces signal transmission and obstructs, and the dielectric constant that has changed PE makes transmission attenuation less.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As Fig. 1, the low decay corrugated coaxial cables of a kind of lightweight, comprises inner wire 1, aluminium outer conductor 3, between inner wire 1 and aluminium outer conductor 3, be provided with insulator 2, on aluminium outer conductor 3, cover has sheath 4, described aluminium outer conductor 3 to be multiple annulus connection shapes, and the diameter of aluminium outer conductor 3 is 0.25cm.
Coaxial cable of the present utility model changes original copper outer conductor into aluminium outer conductor, and cable quality is lightened, and is convenient to transportation and installs; Outer conductor is multiple annulus and connects shape simultaneously, as the annulus of sugarcoated haws stringing together one by one, the bending radius needing because of cable for this reason does not need very little, so the shape that outer conductor adopts multiple annulus to connect just meets indices, again can be when producing convenient production; The diameter of aluminium outer conductor is 0.25cm, reduces signal transmission and obstructs, and the dielectric constant that has changed PE makes transmission attenuation less.Coaxial cable shield decay of the present utility model is less than 120dB; Be less than-26d of return loss; Transmission speed ratio is 88%, and repeated flex radius is 510mm.
