A special cable for flexible d-type communication power supply

Abstract

The invention discloses a flexible D-shaped special cable for communication power supply, which includes a cable core, a shielding layer and a sheath layer arranged sequentially from inside to outside, and the cable core includes a spiral twisted elastic plate, two "D" shaped copper The conductor and the insulating layer covering the outside of the "D"-shaped copper conductor, the straight sides of the two "D"-shaped copper conductors are respectively close to the two sides of the elastic plate and extend in a spiral shape. When the cable of the present invention is pressed, since the cross-sectional length of the elastic plate is greater than the diameter of the “D”-shaped copper conductor, the external force is first applied to the elastic plate, so that the degree of distortion of the elastic plate at the stressed position of the elastic plate increases. On the one hand, the elastic plate itself Twisting will slow down part of the pressure. On the other hand, when the twist of the elastic plate increases, the degree of "twisting" of the two "D"-shaped conductors will increase, and the pressure will act on the length of the "D"-shaped conductor to avoid external pressure. Directly acting on the cross-section of the D"-shaped conductor, causing the "D"-shaped conductor to break.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a flexible D-type special cable for communication power supply. Background technique [0002] 4G communication technology is the fourth generation of mobile information system. It is a better improvement on 3G technology. A good combination makes the transmission speed of the image faster, and makes the quality of the transmitted image and the image look clearer. The application of 4G communication technology in smart communication devices allows users to surf the Internet faster, and the speed can be as high as 100Mbps. At present, my country's 4G network has covered 95% of the country's administrative villages and 99% of the population. However, with the rapid development of mobile communication technology, 5G communication network will provide the main support for the Internet of Everything in the future, enabling cloud services, Internet of Things, autonomous driving, smart ...

AI Technical Summary

Problems solved by technology

However, traditional communication power cables mostly use circular conductors, and the outer diameter of the cable is large. Considering that 5G requires more communication power cables, diameter reduction has become the direction of research and development of new adaptive cables.
