Description

Technical Field

[0001] The utility model relates to the technical field of cables, and more specifically, it relates to a communication cable with high electromagnetic shielding. Background Technique

[0002] A cable is a combination of electric wires used for transmitting electricity, signals or data. It usually consists of one or more insulated wires, and is wrapped with insulating layers, sheaths and other protective materials on the outside. Among them, a communication cable is a cable used for transmitting signals and plays a crucial role in the modern communication field.

[0003] At present, the electromagnetic shielding of communication cables is achieved by weaving metal wires outside the insulating layer of the cable to form a shielding layer. The braided shielding has good flexibility and mechanical strength, and is suitable for occasions that require frequent bending and movement. Metal foil can also be used to wrap outside the insulating layer of the cable as a shielding layer. The shielding effect of the metal foil shielding is better, but it is relatively hard and not very suitable for occasions that require frequent bending. A better shielding effect can be obtained by combining the two methods. However, there are some potential problems in the actual application process of this kind of communication cable. If this kind of communication cable is used for a long time, over time, the metal foil inside the cable will gradually be damaged due to the action of external factors. On the other hand, when this kind of communication cable is bent, especially in the case of frequent bending or a large bending angle, the metal foil inside is extremely easy to be deformed or even damaged under the action of mechanical stress. At the bending point, it is easy to cause the metal foil in the local area to break. The broken metal foil will cause damage inside the cable and affect the transmission rate of the communication cable.

[0004] Therefore, a communication cable with high electromagnetic shielding is proposed, which can achieve electromagnetic shielding, while improving the mechanical properties of the cable and extending the service life of the cable. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a communication cable with high electromagnetic shielding, high bending ability and capable of extending the service life of the cable.

[0011] The present utility model is further configured such that: the wire hole is arranged in a circular structure and penetrates through the aluminum foil shielding, and a plurality of groups of shielding aluminum wires are arranged in a surrounding manner between the outer wall of the inner layer insulation protection and the outer layer insulation.

[0012] By adopting the above technical solutions, the shielding aluminum wires shield the influence of external electromagnetic on the communication cable, reduce the influence of the external high electromagnetic environment on the communication system, and further reduce the influence of the external high electromagnetic environment on the communication system through the aluminum foil shielding, while protecting the internal cable.

[0013] The present utility model is further configured such that: the wire insulation is arranged in a hollow cylindrical structure, the wire insulation is arranged outside the communication cable, and a central shielding is arranged at the center of a plurality of groups of wire insulation.

[0014] The present utility model is further configured such that: the central shielding is arranged in a cylindrical structure and its diameter is smaller than the wire insulation.

[0015] By adopting the above technical solutions, the wire insulation provides insulation for the internal cable. During the installation and use of the communication cable, it will be affected by various external forces, such as stretching, bending, torsion, etc. The outer layer wire fixing can provide additional support and tensile strength for the cable, preventing the cable from being easily broken or damaged under these external forces, ensuring the stability and reliability of communication. The central shielding further provides additional support and tensile strength for the cable, ensuring the stability and reliability of communication. At the same time, the outer layer wire fixing can limit the bending angle of the overall communication cable, reducing the damage of the aluminum foil shielding caused by excessive bending and affecting the service life of the cable.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:
