Description
Technical Field
The present invention relates to a cable, and more particularly, to a cable structure with an anti-crosstalk structure.
Background
In the network system, the network cable plays a role in transmitting signals in the connected devices, and at the step of the more developed networks, the signals to be transmitted by the network cable are required to be faster and faster, and therefore, the environment of the current network establishment tends to be densely arranged, and each arranged network cable tends to be compact.
When the network cable transmits signals, the core wires transmitting signals in each network cable can emit electromagnetic waves, and if the transmission efficiency in the network cable is improved, the electromagnetic waves emitted by other core wires need to be isolated or reduced so as not to influence the signals transmitted by the network cable.
In order to solve the above problem, the conventional art such as US patent No. 7772494 discloses a structure of an isolation bracket, which is formed by combining two H-shaped brackets in a staggered manner and forming four isolation channels, wherein four twisted pairs in a network cable are respectively placed in one isolation channel, the interference between the four twisted pairs is reduced by a spacer, and two salient points are additionally designed on the spacer outside the H-shaped bracket at two ends of the spacer, and the structure mainly makes two adjacent network cables separated by the salient points when a plurality of network cables are close to each other; however, although the bracket of this design effectively blocks crosstalk between the four twisted pairs and also effectively prevents crosstalk of the external network cable, the complementary twisted pairs are isolated and thus the complementary effect is reduced, and the cost is increased compared to the cross-shaped isolation bracket of the prior art.
In addition, the prior art such as JP2004311120a also discloses a T-shaped isolation frame structure, which is used to isolate the interior of the cable into 3 core channels, and two pairs of four twisted pairs of the network cable are placed in one core channel, and the other two pairs are placed in one core channel; similarly, there is a prior art such as U.S. Pat. No. 5, 7897875 which discloses a T-shaped isolation stent structure, and based on the contents of the above mentioned Japanese patent, further discloses a design in which the second long pair twist and the shortest pair twist are placed in the same core wire channel, and the longest pair twist and the second short pair twist are placed in the other two core wire channels respectively; although the above-mentioned T-shaped bracket design further has no isolation between the complementary twisted pairs, so that the complementary twisted pairs can perform a complementary action on signals and can also isolate crosstalk of the other twisted pairs, in such a structure, crosstalk interference of external network cables cannot be effectively avoided, which is a disadvantage of this technique.
