Problems solved by technology

[0002] At present, the common cables in the market are wrapped with paper tape inside. The paper tape has high hardness and high dielectric constant, resulting in low flexibility of the cable, which may fail to pass the bending test, and the impedance of the cable is high, and the signal generated during transmission High loss, sometimes unable to meet the high requirements of customers

Embodiment Construction

[0008] see figure 1 As shown, the cable 10 of the present invention includes several conductors 11, an insulator 12 wrapped around the conductors 11 from inside to outside, an aluminum foil layer 13, a tape 14, an aluminum foil Mylar layer 15, a braided layer 16 and an outer layer 17.

[0009] The conductors 11 can be differential signal conductors, power supply conductors or ground conductors, and each pair of differential signal conductors is wrapped with the same aluminum foil layer 13 .

[0010] The wrapping tape 14 is wrapped around the outer side of the aluminum foil layer 13. The wrapping tape 14 is foamed and molded from PP (polypropylene), and a number of air bubbles 141 are formed inside. The wrapping tape 14 has low hardness, which makes the cable 10 relatively soft and easy to bend. When 10 is squeezed, stress buffering can be provided to protect the conductor 11 from being damaged. In addition, the dielectric constant of the wrapping tape 14 is low, which is benef...

Abstract

The invention relates to a cable which comprises a conductor, an insulator, wrapping tape and an outer covering layer. The periphery of the conductor is wrapped by the insulator, the wrapping tape is formed by foaming PP materials, a plurality of bubbles are formed inside the wrapping tape, the hardness of the wrapping tape is low, the cable is flexible, and is easily bent, when the cable is extruded, stress buffer can be provided, the conductor is protected against damage, in addition, a dielectric constant of the wrapping tape is lower, the resistance of the cable and the signal losses can be easily reduced, and the transmission quality of cable signals can be improved.

Description

technical field [0001] The invention relates to a cable. Background technique [0002] At present, the common cables in the market are wrapped with paper tape inside. The paper tape has high hardness and high dielectric constant, resulting in low flexibility of the cable, which may fail to pass the bending test, and the impedance of the cable is high, and the signal generated during transmission The loss is large, and sometimes it cannot meet the high requirements of customers. [0003] Therefore, it is necessary to improve the above technical problems. Contents of the invention [0004] It is an object of the present invention to provide a cable with improved flexibility. [0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a cable, which includes a conductor, an insulator wrapped around the conductor, a tape, and an outer layer, and is characterized in that: the tape is foamed from PP material , formi...
