Problems solved by technology

[0005] However, the transmission frequency of the existing Category 6 data cables that are widely used is relatively low. Therefore, in the product structure design, the core wire is generally solid plastic insulation, and the outside adopts an unshielded or single-layer metal foil shielding structure.
With such a structural design, it is difficult to ensure that the product has good electrical and transmission performance and anti-electromagnetic interference performance when the transmission bandwidth exceeds 250MHz.

Embodiment Construction

[0023] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 Shown is an insulated and foamed 10 Gigabit data cable. The data cable is composed of a low-smoke and halogen-free material protection layer 1, a total shielding layer 2 and four sets of wire pairs 3. The low-smoke and halogen-free material protection layer 1 is located on the data cable. The outer layer, the overall shielding layer 2 is set in the low-smoke and halogen-free material protective layer 1, and a metal braid layer with a coverage area of ​​45% is selected, and a tear is provided between the overall shielding layer 2 and the low-smoke and halogen-free material protective layer 1 rope10. The four groups of wire pairs 3 are arranged in the general shielding layer 2, and the four groups of wire pairs 3 are respectively composed of two wires 5 and a sub-shielding layer 4. The wires 5 are wrapped ...

Abstract

The invention relates to data cables in the technical field of electronic information, particularly relates to a data cable with ultra-large capacity and a high shielding property for transmitting data signals such as audios, videos and images at a high speed, and discloses an insulating foam ten-gigabit data cable which comprises a PVC (polyvinyl chloride) protective layer, a main shielding layer and four groups of wire pairs. The PVC protective layer is positioned on an outer layer of the data cable, the main shielding layer is arranged inside the PVC protective layer, a tearing rope is arranged between the main shielding layer and the PVC protective layer, the four groups of wire pairs are arranged in the main shielding layer, each group of wire pairs comprises two conducting wires and a branch shielding layer, the two conducting wires of each group of wire pairs are wrapped together by the corresponding branch shielding layer, and each conducting wire sequentially comprises a copper conductor, a first solid PE (polyethylene) insulating layer, a high-physical-foaming layer and a second solid PE insulating layer from inside to outside. The data cable has the advantages that loss of signals is effectively reduced when the signals are transmitted in the conductors, and the integral electromagnetic interference resistance and the signal crosstalk interference resistance of a product are improved.

Description

technical field [0001] The invention relates to a data cable in the field of electronic information technology, in particular to a data cable with high shielding performance used for high-speed transmission of super-large-capacity audio, video, image and other data signals. Background technique [0002] With the continuous development of information networks, information communication is becoming more and more frequent, and the information exchange capacity is also increasing. Data cable is an important transmission medium for network information. In the face of new technological changes and innovations, on the one hand, it is necessary to increase the transmission rate to meet the transmission and exchange of large-capacity information. On the other hand, it is necessary to improve the transmission stability to ensure the quality of information transmission. [0003] Over the past 30 years since the advent of Ethernet, the network transmission rate has increased nearly a th...
