Description

Cable structure

This creation is about a cable, especially a cable structure with anti-interference crosstalk structure.

In the network system, the network cable plays the role of transmitting signals in the connected equipment. In the footsteps of today's increasingly developed network, the signals transmitted by the network cable are also required to be faster and faster. The environment in which the network is built also tends to be densely arranged, so that each network cable that is laid will also tend to be tight.

When the network cable is transmitting signals, the core wire of each network cable will emit electromagnetic waves. To improve the transmission efficiency in the network cable, the electromagnetic waves emitted by other core wires must be isolated or reduced. In order not to affect the signal transmitted by itself.

In order to solve this phenomenon, the conventional technology such as the US Patent No. US7772494 discloses a structure of an isolation bracket, which is composed of two H-shaped brackets combined in a misaligned manner, and forms four isolation channels. Put the twisted pairs into an isolation channel, and reduce the mutual interference between the four twisted pairs by the spacer. In addition, two spacers are designed on the spacer outside the H-shaped bracket at both ends of the spacer. This structure is mainly used when a plurality of network cables are close to each other, two adjacent network cables can be separated by a bump; however, although the bracket of this design effectively blocks four twisted pairs Crosstalk interference, and can also effectively prevent external network power The crosstalk interference of the cable, but also produces complementary effects between the complementary twisted pairs due to the isolation relationship. At the same time, compared with the more conventional technology cross isolation bracket, the cost will also increase.

In addition, the conventional technology such as Japanese Patent JP2004311120A also discloses a T-shaped isolation bracket structure, by which the cable interior is isolated into three core wire channels, and two pairs of four pairs of network cables are placed in the network cable. Into a core wire channel, and the other two pairs are placed in a core wire channel; similarly, there is a conventional technology such as US Patent US7897875 which discloses a T-type isolation bracket structure, which is based on the contents of the aforementioned Japanese patents. It reveals the design that the pitch of the second longest twisted pair and the shortest twisted pair are placed in the same core wire channel, while the design of the longest twisted pair and the second short twisted pair pitch are placed in the other two core wire channels respectively; The design of the aforementioned T-shaped bracket further isolates the complementary twisted pairs, so that the complementary twisted pairs can complement each other on the signal, and can also isolate the crosstalk of the remaining twisted pairs, but in this structure On the other hand, it cannot effectively avoid crosstalk interference from external network cables, which becomes the lack of this technology.

In response to the above deficiencies, the main purpose of this creation is to provide a cable structure with an isolation bracket, which is provided with an internal isolation sheet and a protective sheet structure to block crosstalk interference from adjacent cable lines and effectively improve the external string At the same time, the ability of the sound, at the same time, the plural core wires arranged in the same channel twisted pair also form a complementary role.

To achieve the above purpose, this creation mainly provides a cable structure, which mainly includes a tube body, a main isolator is provided in the tube body, and a first isolator is connected at the center of the main isolator and vertically connected. A first protective sheet and a second protective sheet are respectively connected at two ends of the main isolating sheet and the two protective sheets are connected to the main isolating sheet at an angle, wherein the first protective sheet is lower than The position of the outer peripheral surface of the main spacer is in an arc shape, and the position of the second guard plate is triangular than the position of the outer peripheral surface of the main spacer. The main spacer and the first and second guard plates form a first A channel, the main spacer and the first shield and the first spacer form a second channel, the main spacer and the second shield and the first spacer form a third channel, the first channel A plurality of twisted pairs are provided, a single twisted pair is provided in the second channel, and a single twisted pair is provided in the third channel.

As a result, the aforementioned twisted pairs can be fixed in the first channel, the second channel, and the third channel through the first shield and the second shield, respectively, and the first shield and the second shield can block the phase The crosstalk interference from the adjacent cable, at the same time, the structure of the main isolation plate and the first isolation plate, and then isolate the twisted pairs of the first channel, the second channel and the third channel Interference, and the plural core wires respectively arranged in the twisted pairs of the same channel form a complementary effect.
