Description

Technical Field

[0001] This utility model relates to the field of digital communication cable technology, and specifically to a high-frequency digital communication cable. Background Technology

[0002] Currently, with the development of science and technology, industries and other fields are also making rapid progress, which leads to an increase in the use of cables. Cables are usually rope-like cables with several or several groups of conductors, each group having at least two conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. There are many types of cables, which can be used in many fields. However, the usage environment in different fields is different, so there are also different requirements for cables.

[0003] The specification of an industrial high-frequency digital communication cable (publication number CN205211454U) mentions that "the cable body includes a conductor, a reinforcing layer, an insulation layer, and an outer sheath; multiple conductors are arranged inside the cable body; the multiple conductors arranged inside the cable body are isolated by an isolation bracket; a reinforcing layer is wrapped around the conductor; an insulation layer is extruded around the reinforcing layer; an anti-aging layer is extruded around the insulation layer; an anti-tracking layer is extruded around the anti-aging layer; a steel strip reinforcing layer is extruded around the anti-tracking layer; a moisture-proof layer is extruded around the steel strip reinforcing layer; and an outer sheath is extruded around the moisture-proof layer." However, the cable in the prior art is not fireproof or wear-resistant on the outside, nor is it pressure-resistant or bend-resistant on the inside, making it neither safe nor reliable. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a high-frequency digital communication cable is provided to solve the problems that existing cables are not fireproof and wear-resistant on the outside, not pressure-resistant or bending-resistant on the inside, and are not safe, reliable, or practical.

[0005] To achieve the above objectives, a high-frequency digital communication cable is provided, comprising a conductor, a shielding layer, and an outer sheath. The conductor is located within an inner insulation layer, and an inner buffer layer is disposed outside the inner insulation layer. A shielding layer is disposed outside the inner buffer layer, and multiple bending resistance strips are disposed on the outer ring surface of the shielding layer. An inner filler is disposed outside the shielding layer, and an outer sealing layer is disposed outside the inner filler. An outer fireproof layer is disposed outside the outer sealing layer, and an outer wear-resistant layer is disposed outside the outer fireproof layer. An outer sheath is disposed outside the outer wear-resistant layer.

[0006] Furthermore, the gaps within the inner insulation layer are filled with an inner filler material, which is made of PP plastic.

[0007] Furthermore, the inner insulation layer is made of cross-linked polyethylene, and the inner buffer layer is made of silicone rubber.

[0008] Furthermore, the shielding layer is made of aluminum foil, and the bending strip has a trapezoidal cross-section. Two sets of reinforcing wires are threaded through the bending strip, and the reinforcing wires are made of thin iron wire.

[0009] Furthermore, the filler is made of TPU elastic plastic, and the outer sealing layer is made of PE material.

[0010] Furthermore, the outer fireproof layer is made of polyolefin material, and the outer wear-resistant layer is made of PU material.

[0011] Furthermore, the outer wrapping layer is made of polyvinyl chloride, and multiple anti-slip strips are provided on the outer ring surface of the outer wrapping layer.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses an inner insulation layer to wrap multiple sets of conductors, and fills the gaps inside with an inner filler to enrich the internal structure of the cable, reducing mutual wear between conductors, and then uses an inner buffer layer to buffer external compression.

[0014] 2. The shielding layer in this utility model helps to generate partial discharge inside the shielded cable, and the use of anti-bending strips and reinforcing wires to strengthen the cable body makes it less prone to bending and more robust and durable.

[0015] 3. In this utility model, the space in the middle area of ​​the cable is filled with a filler material to make it fuller and more complete. Then, a safety seal is achieved through an outer sealing layer, followed by an outer fireproof layer and an outer wear-resistant layer for fire resistance and wear resistance, thus extending the service life of the equipment.

[0016] 4. The outer wrapping layer in this utility model can effectively prevent these mechanical forces from damaging the internal structure of the cable, protecting the integrity and safety of the cable, and the anti-slip strip provides a safe and anti-slip effect, making it safer and more durable.
