Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable for communication power supply. Background Art

[0002] With the continuous development of science and technology, the development of communication technology is also getting faster and faster. People's lives are increasingly inseparable from the use of communication equipment, and the development of communication technology is inseparable from the use of communication power cables. The current cables have weak anti-interference ability during use, which easily affects signal transmission and reduces transmission efficiency. In addition, if the existing communication cables on the market are strongly pulled out during use, they will break, which will bring inconvenience to subsequent use and work. Utility Model Content

[0003] In view of this, in order to solve the problem of messy cables in the technical background, the utility model proposes a communication power cable, and the specific technical solution is as follows:

[0004] A communication power cable comprises a cable body, wherein a plurality of wire cores are arranged inside the cable body, an insulating layer wrapped around the outside of the wire cores and a support plate, wherein the support plate is trident-shaped, the wire cores and the insulating layer are placed inside the support plate, an elastic sheath is arranged on the outer peripheral surface of the support plate, a plurality of elastic rubber blocks are fixedly connected inside the elastic sheath, and a first shielding layer, a second shielding layer and a wear-resistant layer are arranged on the outside of the elastic sheath in sequence from the inside to the outside.

[0005] Furthermore, the first shielding layer is a copper mesh layer, and the second shielding layer is made of a high magnetic permeability material. The second shielding layer can shield low-frequency interference signals, and the copper mesh layer can shield high-frequency interference signals.

[0006] Furthermore, the elastic rubber blocks are arranged in a ring shape around the elastic sheath. When the cable is pulled, the elastic sheath and the elastic rubber blocks can share the pulling force when the cable is pulled, thereby improving the overall anti-pulling performance of the outer sheath of the cable.

[0007] Furthermore, a moisture-proof layer is filled between the support plate and the insulating layer to increase the moisture-proof effect of the cable body.

[0008] Furthermore, the wire core is fixed in the isolation plate, which provides support and protection for the wire core.

[0009] Furthermore, the moisture-proof layer is made of polyethylene synthetic polymer material.

[0010] Furthermore, the insulating layer is made of synthetic resin.

[0011] The above technical solution has the following beneficial effects:

[0012] The utility model arranges a first shielding layer and a second shielding layer inside the cable body, which can shield low-frequency interference signals and high-frequency interference signals, and arranges an elastic sheath and a plurality of elastic rubber blocks outside the wire core. When the cable is pulled, the elastic sheath and the elastic rubber blocks can share the pulling force when the cable is pulled, thereby improving the overall anti-pulling performance of the outer sheath of the cable and extending the service life of the cable.
