Problems solved by technology

Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. Composed of multi-strand wires and insulating layers, it is used to connect circuits, electrical appliances, etc.; with the rapid development of information technology, people have higher and higher requirements for network speed. With the development of cloud computing and big data, the widely used six Such unshielded wiring systems can no longer meet some higher requirements when used in buried ground, especially when Ethernet is used in buried ground, it is required to be able to withstand pressure and waterproof, and when used in harsh environments, the characteristic parameters of data cables are prone to instability. : Near-end crosstalk interference. The unshielded structure used in the prior art is not enough to prevent external electromagnetic radiation from entering the cable. In harsh environments, traditional network cable wiring generally adopts pipe-pipe wiring instead of direct buried use, and cannot Load-bearing and tensile, and with the increase of network speed and frequency, the interference of the environment on the cable is increasing. These factors have become the main factors affecting the transmission effect of the cable. Therefore, a new solution is urgently needed to solve this technical problem.

Embodiment 1

[0017] Example 1 : see figure 1 , Ethernet with six types of shielded armored symmetrical data cable, said symmetrical data cable from outside to inside includes a core outer sheath 12, a non-woven fabric layer 13, a steel wire armor layer 7, a double-layer inner sheath, and a Four sets of cable cores inside the inner sheath, the double-layer inner sheath includes a first inner sheath 4 and a second inner sheath 5, the first inner sheath 4 and the second inner sheath 5 is arranged between the steel wire armor layer 7 and the cable core. The double jacket improves the communication capability and reliability of the cable. This technical solution can effectively improve the possibility of harsh environments and communication data cables being buried in the ground, and the addition of steel wire armor layers improves the load-bearing and tensile resistance of communication data cables, and is easy to use and simple to lay.

Embodiment 2

[0018] Example 2 : see figure 1 , as an improvement of the present invention, a tear rope 3 is arranged between the cable core and the double-layer inner sheath to improve the tensile and compressive resistance of the cable, and a cross frame filling strip 6 is arranged in the cable core , each group of cable cores includes a group of twisted wires 8, the cross frame filler strip divides the cable core into four partitions, each partition is placed with a group of twisted wires, and each group forms a separate cavity, which can effectively Eliminate electromagnetic mutual interference between wire pairs and obtain excellent transmission performance results. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0019] Example 3 : see figure 1 , As an improvement of the present invention, each cable core is composed of 4 pairs of twisted wires 8, and each pair of twisted wires 8 includes 2 insulated wire cores, each insulated wire core has a copper conductor and a cladding layer. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a category 6 shielding armoured symmetric data cable used for an Ethernet. The cable is characterized in that the symmetric data cable comprises a core body outer sheath, a non-woven fabric layer, a steel wire armoured layer, a double-layer inner sheath and four groups of cable cores arranged in the inner sheath, which are arranged from outside to inside. The double-layer inner sheath comprises a first inner sheath and a second inner sheath, and the first inner sheath and the second inner sheath are arranged between the steel wire armoured layer and the cable cores. According to the scheme, the steel wire armoured layer and the double-layer inner sheath layer are arranged, the possibility of the communication data cable to be used in a severe environment and the possibility of burying of the communication data cable are effectively improved, and the bearing capability and the electromagnetic interference resistance of the communication data cable are improved.

Description

technical field [0001] The invention relates to a cable, in particular to a six-category shielded and armored symmetrical data cable for Ethernet, belonging to the technical field of communication cables. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering.
