Description

Improved UTP communication cable

Technical Field

The utility model relates to a communication cable technical field specifically is an improved generation UTP communication cable.

Background

The conventional communication cables are UTP, FTP, STP and SFTP, the UTP communication cable is unshielded, the FTP communication cable is shielded by aluminum foil, the STP communication cable is shielded by weaving, and the SFTP communication cable is shielded by the way of weaving with aluminum foil. UTP has no problem when manufacturing category 5 or category 5e cables, but when manufacturing category 6 or category 6A cables, it often fails crosstalk tests (detection of presence or absence of signal interference) between the external near end and the external far end, and although some other types of communication cables such as FTP can pass the crosstalk tests, their cost is high. And FTP communication cable leads to when cutting off the sheath, still need peel off the aluminium foil layer, and the operation is more loaded down with trivial details, is unfavorable for the construction.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the problem that prior art exists, an improved generation UTP communication cable with shielding effect is proposed.

The utility model provides a technical scheme that its technical problem adopted is: an improved UTP communication cable comprises

Four twisted pairs, wherein each twisted pair comprises two homochromatic transmission lines;

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to fig. 3, an improved UTP communication cable includes four twisted pairs, the twisted pairs include two transmission lines of the same color, an isolation framework 2 for isolating the four twisted pairs, an aluminum foil layer 3 covering the four twisted pairs, and a sheath 4 covering the aluminum foil layer 3, and the UTP communication cable is shielded by adding the aluminum foil layer 3. The thickness of the aluminum foil of the FTP communication cable is required to meet the industrial standard, and therefore the thickness is not lower than 0.07 mm, and the UTP communication cable is not limited by the thickness of the aluminum foil, so that the thickness of the aluminum foil layer 3 can be reduced as far as possible on the premise of achieving the shielding effect, on one hand, the cost is reduced, on the other hand, the overall diameter of the UTP communication cable is not increased too much, and a large number of experiments prove that the cost performance is optimal when the thickness of the aluminum foil layer 3 is 0.036 mm, namely, the aluminum foil layer 3 with the thickness can enable the UTP communication cable to pass crosstalk tests of an external near end and an external far end, and.

In addition, compared with the FTP communication cable, the UTP communication cable does not need to be provided with a PET polyester film and a drainage wire, so that the cost is further reduced.

Aluminium foil layer 3 with 4 contact surfaces of sheath are equipped with self-adhesive layer 31, and self-adhesive layer 31 can be with 3 and 4 adhesions of sheath on the aluminium foil layer, once only subtracts removal with sheath 4 and aluminium foil layer 2 when being favorable to constructing, is convenient for construct.

The sheath 4 is annular, and 6 types and above 6 types UTP communication cable of prior art, in order to improve the support intensity of sheath 4, the inside zigzag of sheath 4 strengthens the setting, and the UTP communication cable of this application is because aluminium foil layer 3 has been add, and its support intensity has obtained improving, so need not add the zigzag arch in sheath 4 inside for the cost of sheath 4 obtains reducing, and has reduced the thickness of sheath 4, thereby can reduce UTP communication cable's whole diameter.

The transmission line comprises a wire core 11 and an insulating layer 12 coated outside the wire core 11, wherein the insulating layer 12 is in a flat oval shape, so that the space utilization rate is improved, and the overall diameter of the UTP communication cable can be further reduced.

The isolation framework 2 plays a supporting role on one hand, and can prevent four twisted pairs from interfering with each other on the other hand. When the shielding effect required by the UTP communication cable is high, the metal shielding layer 21 may be coated on the isolation surface of the isolation framework 2, or the metal shielding body 22 may be filled inside the isolation framework 2 to further improve the anti-interference performance of the UTP communication cable.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
