Abstract
The present invention discloses a flexible D-type communication power supply dedicated cable, comprising a cable core, a shielding layer and a sheath layer arranged in order from inside to outside, wherein the cable core comprises an elastic plate in the form of a spiral twist, two pressed "D"-shaped copper conductor and an insulation layer coated outside the pressed "D"-shaped copper conductor; and straight edges of the two pressed "D"-shaped copper conductor respectively abut against two side edges of the elastic plate to extend in a spiral shape. When the cable of the present invention is compressed, external force is first applied to elastic plate due to the fact that the cross-sectional length of the elastic plate is larger than the diameter of the "D"-shaped copper conductor, so that the distortion degree of elastic plate increases at the location of the elastic plate stressed. On the one hand, the twisting of the elastic plate itself would mitigate a part of the pressure; and on the other hand, when the distortion degree of the elastic plate increases, the two "D"-shaped conductor has an increased "stranding" degree, thus putting a pressure action on the length direction of "D"-shaped conductor and avoiding the direct action of external pressure on the cross-section of "D"-shaped conductor to result in the fracture of "D"-shaped conductor.
Description
BL-5467 LU501921 Flexible D-type communication power supply dedicated cable Technical Field The present invention relates to the technical field of cables, in particular to a flexible D-type communication power supply dedicated cable.
Background Art 4G communication technology 1s the fourth generation of mobile information system, which 1s a better improvement on 3G technology.
It has a greater advantage compared with 3G communication technology.
It is a good combination of WLAN technology and 3G communication technology, so that the transmission speed of images is faster, and the quality of transmitted images and images look clearer.
Applying 4G communication technology in an mtelligent communication device makes the user's speed of surfing the Internet much faster, which is up to 100 Mbps.
At present, china'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 interconnection of everything in the future, so that cloud service, Internet of Things, autonomous driving, intelligent home, real-time VR/AR and other scenarios can be realized.
It can be said that "4G changes life, and 5G changes society”. The construction of 5G communication network has become the world's target.
However, due to the high frequency of 5G communication and large signal propagation attenuation, the base station density of 5G network will be higher than that of 4G base stations.
Also, the large energy consumption of 5G communication will make the construction of 5G base station difficult.
If the original 4G line can be used, the investment cost will be reduced.
However, the cable for traditional communication power mostly uses circular conductors, and the cable outer diameter is large.
Considering that 5G needs more communication power cable, the diameter reduction has become the direction of research and development of new adaptive cables.
Based on this, a new type of flexible D-type communication power supply dedicated cable comes into being.
Summary of the Invention It is an object of the present invention to provide a flexible D-type communication power supply dedicated cable to solve the problems set forth in the above background art.
In order to achieve the above object, the present invention provides the following technical solutions: a flexible D-type communication power supply dedicated cable comprising a cable core,
BL-5467 a shielding layer and a sheath layer arranged in order from inside to outside, wherein the cable LUS01921 core comprises an elastic plate in the form of a spiral twist, two pressed "D"-shaped copper conductors and an insulation layer coated outside the pressed "D"-shaped copper conductor; straight edges of the two pressed "D"-shaped copper conductors respectively abut against two side edges of the elastic plate to extend in a spiral shape; a composite strip is wrapped outside the elastic plate and the two pressed "D"-shaped copper conductors; and two end faces of the elastic plate between the composite strips are respectively provided with a protrusion (15). Preferably, the "D"-shaped copper conductor is stranded by a plurality of fine soft copper wires, and compressed for formation.
Preferably, the composite strip 1s an aluminum-plastic composite strip.
Preferably, the shielding layer is a copper wire braid combined shielding layer.
Preferably, the cross-sectional length of the elastic plate is greater than the diameter of the "D"-shaped copper conductor.
In contrast to the prior art, the present invention has following advantageous effects. (1) The conductor of the present invention is stranded by a plurality of fine soft aluminum alloy wires stranding, and compressed for formating a "D"-shaped conductor, which can reduce the cable outer diameter by about 10%, the cable weight by about 15%, and the cost by about 6%. (2) The cable core of the present invention has an excellent anti-electromagnetic interference effect by providing the aluminum-plastic composite strip and the copper wire braid combined shielding layer. (3) The elastic plate of the present invention is helically twisted, and straight edges of two pressed "D"-shaped copper conductors are helically extended against two side edges of the elastic plate, respectively.
When the cable is compressed, external force is first applied to the elastic plate due to the fact that the cross-sectional length of the clastic plate is larger than the diameter of the "D"-shaped copper conductor, so that the distortion degree of elastic plate increases at the location of the elastic plate stressed.
On the one hand, the twisting of the elastic plate itself would mitigate a part of the pressure; and on the other hand, when the distortion degree of the elastic plate increases, the two "D"-shaped conductor has an increased "stranding" degree, thus putting a pressure action on the length direction of "D"-shaped conductor and avoiding the direct action of external pressure on the cross-section of "D"-shaped conductor to result in the fracture of "D"-shaped conductor.
When a "stranding" degree of the two "D"-shaped conductors increases, there will also be a part of force on the clastic plate along the length direction, making a further mitigation on the external pressure and protecting the "D"-shaped conductor. (4) The composite strip is wrapped outside the clastic plate of the present invention and the two pressed "D"-shaped copper conductor, and the two end faces of the elastic plate between the
BL-5467 composite strips are respectively provided with a protrusion.
When the cable is pulled from the LUS01921 outside, the composite strip is displaced by pulling force so that its spiral edge pushes the protrusion of the elastic plate, which leads to the change of elastic plate towards a flat state.
When the elastic plate changes towards the flat state, on the one hand, the elastic plate itself changes to mitigate a part of pulling force.
On the other hand, when the elastic plate changes towards the flat state, the "stranding" degree of the two "D"-shaped conductors are smaller, the two "D"-shaped conductors at the position subjected to the pulling force turn to a relaxed state, avoiding the use of external pulling force on the "D"-shaped conductor and protecting the "D"-shaped conductor.

Detailed Description of the Invention The technical solution in the embodiment of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiment of the present invention.
It is obvious that the described embodiments are only a part of the embodiments of the present invention, rather than the whole embodiments.
Based on the embodiments in the present mvention, all other embodiments obtained by a person of ordinary skill in the art without mvolving any inventive effort fall within the scope of protection of the present invention.
Referring to Figs. 1-4, the present invention provides a embodiment.
A flexible D-type communication power supply dedicated cable is characterized by comprising a cable core 1, a shielding layer 2 and a sheath layer 3 arranged in order from inside to outside, wherein the cable core 1 comprises an clastic plate 11 in a spiral twisted shape, two pressed "D"-shaped copper conductors 12 and an insulation layer 13 coated outside the pressed "D"-shaped copper conductor 12; straight edges of the two pressed "D"-shaped copper conductors 12 respectively abut against two side edges of the elastic plate 11 to extend in a spiral shape; a composite strip 14 is wrapped outside the elastic plate 11 and the two pressed "D"-shaped copper conductors 12; and two end faces of the elastic plate 11 between the composite strips 14 are respectively provided with a protrusion 15; the "D"-shaped copper conductor 12 is stranded by a plurality of fine soft copper
BL-5467 wires and then compressed by a "D"-shaped mould; the composite strip 14 is an aluminum-plastic LUS01921 composite strip 14; the shielding layer 2 is a copper wire braid combined shielding layer 2; the cross-sectional length of the elastic plate 11 is larger than the diameter of the "D"-shaped copper conductor 12. Working principle.
In application, since the conductor is stranded by a plurality of fine soft aluminum alloy wires stranding, and compressed for forming a "D"-shaped conductor, which can reduce the cable outer diameter by about 10%, the cable weight by about 15%, and the cost by about 6%. In addition, the aluminum-plastic composite strip 14 and the copper wire braid combined shielding layer 2 are provided outside cable core 1, producing an excellent anti-clectromagnetic interference effect.
When the cable is under compression, the external force is first applied to the elastic 11 plate due to the fact that the cross-sectional length of the elastic plate 11 is larger than the diameter of the "D"-shaped copper conductor 12, so that the elastic plate 11 has an increased distortion degree at the location where the elastic plate 11 is forced.
On the one hand, the twisting of the elastic plate 11 itself would mitigate a part of the pressure; and on the other hand, when the distortion degree of the elastic plate 11 increases, the two "D"-shaped conductor 12 has an increased "stranding" degree, thus putting a pressure action on the length direction of "D"-shaped conductor 12, and avoiding the direct action of external pressure on the cross-section of the "D"-shaped conductor 12 to result in the fracture of "D"-shaped conductor 12. In addition, when a "stranding" degree of two "D"-shaped conductors 12 increases, there will also be a part of force on the elastic plate 11 along the length direction, making a further mitigation on the external pressure and protecting the "D"-shaped conductor 12. When the cable is pulled from the outside, the composite strip 14 is displaced by pulling force so that its spiral edge pushes the protrusion 15 of the elastic plate 11, which leads to the change of elastic plate 11 towards a flat state.
When the elastic plate 11 changes towards the flat state, on the one hand, the elastic plate 11 itself changes to mitigate a part of pulling force.
On the other hand, when the elastic plate 11 changes towards the flat state, the "stranding" degree of the two "D"-shaped conductors 12 are smaller, the two "D"-shaped conductors 12 at the position subjected to the pulling force turn to a relaxed state, avoiding the use of external pulling force on the "D"-shaped conductor 12 and protecting the "D"-shaped conductor 12. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can make modifications to the technical solutions described in each of the aforementioned embodiments, or make equivalents to some of the technical features thereof.
Thus, it is intended that the present invention cover the modifications, equivalent replacements and variations provided they come within the spirit and principle of the invention.
