Problems solved by technology

However, such a structure makes the electromagnetic interference between several sub-units more serious, and a system with poor shielding performance will destroy the normal transmission of signals, causing errors or leakage of data information transmitted in the cable, affecting the normal communication services to reduce the transmission quality of the system

Embodiment

[0014] Embodiment: As shown in Figure 1, a multi-core sub-shielded broadband cable includes an outer sheath 1, a wrap 2 in the outer sheath 1, and four subunits 3 in the wrap 2, each subunit The unit 3 includes 24 pairs of cables 4 , each subunit 3 is provided with a cable tie 5 , the cable tie 5 is covered with a wrapping tape 6 , and an aluminum-plastic-aluminum tape shielding layer 7 is provided outside the wrapping tape 6 .

[0015] The inner side of the outer sheath 1 can also be provided with a tearing rope 8, which can help to open the outer sheath and make the construction process more convenient.

[0016] The invention adopts the aluminum-plastic-aluminum tape shielding layer. When the frequency of the interference electromagnetic field is high, the eddy current generated in the metal material with low resistivity is used to form a counteracting effect on the external electromagnetic wave, thereby achieving the effect of shielding; it can effectively reduce Electromag...

Abstract

The invention is concerned with the multi-core screen broad-band cable, includes: the oversheath, the lapping in the oversheath, several sub-unit in the lapping. It is: each sub-unit includes several pair of cable that is set the stabbing out of it; the stabbing covers the lapping belt that is set screen layer out of it. The aluminum model aluminum belt screen layer can avoid the interfere between the sub-units effectively that can screen for the radiation and interfere from outside in order to satisfy the need of one tube with multi-core cable of the user.

Description

technical field [0001] The invention relates to a multi-core sub-shielding broadband cable. Background technique [0002] With the advent of the information age, the amount of information transmission has grown explosively. As an effective means of large-capacity and long-distance transmission, electric cables and optical cables have been widely used. A traditional broadband cable includes an outer sheath and a wrapping tape inside the outer sheath. There are several pairs of cables inside the wrapping tape. Each pair of cables is made of two wires glued together, and each wire is provided with an insulating layer. In order to meet the communication needs of more users at the same time, a large number of broadband cables has appeared. Each outer sheath is equipped with multiple subunits, and each subunit contains several pairs of cables. However, such a structure makes the electromagnetic interference between several sub-units more serious, and a system with poor shielding ...
