Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically, it relates to a signal composite cable. Background Technology

[0002] Signal composite cable refers to a signal composite cable, namely OPLC, which is a composite cable that can transmit both electrical energy and signals. Compared with single-function transmission cables, it has the characteristics of high reliability data transmission, low price, and convenient connection, and avoids secondary wiring, thus reducing project costs.

[0003] Because of its multi-functionality, it has been widely used in the laying of communication engineering. However, when laying it outdoors, we have found that it is easily gnawed by rodents, such as rats, which affects its performance. Therefore, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a signal composite cable.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A signal composite cable includes a power line, a shielded mesh cable, a shielded signal cable, and an outer sheath. The power line, shielded mesh cable, and shielded signal cable are arranged inside the outer sheath. An inner sheath separates the outer sheath from the power line, shielded mesh cable, and shielded signal cable. The surface of the inner sheath is coated with a first capsaicin anti-bite layer.

[0007] The outer surface of the outer sheath is fixed with multiple reinforcing protrusions, and each reinforcing protrusion has an inner groove in the middle. The outer sheath, the reinforcing protrusions and the inner groove are all coated with a second capsaicin anti-bite layer.

[0008] The inner sheath is filled with a heat-insulating filling layer for cable rounding.

[0009] Optionally, the inner core of the power cord is a first pure copper conductor, the first pure copper conductor is wrapped with a first polyethylene insulation layer, and the first polyethylene insulation layer is wrapped with a first polyester film.

[0010] Optionally, the inner core of the shielded signal wire is a tin-plated copper conductor, and a second polyethylene insulation layer is provided on the outside of the tin-plated copper conductor. Every two shielded signal wires are twisted together to form a shielded signal wire pair, and the shielded signal wire pair is wrapped with a second polyester film.

[0011] Optionally, the inner core of the shielded wire is a second pure copper conductor, and a third polyethylene insulation layer is provided on the outside of the second pure copper conductor. Every two shielded wires are twisted into one shielded wire pair.

[0012] Optionally, every two shielded mesh wires are twisted together to form a cable and wrapped with a third polyester film. An aluminum film shielding layer is provided on the outside of the two shielded mesh wires, and a first tin-plated copper braided shielding layer is also provided on the outside of the aluminum film shielding layer. The aluminum film coverage is 100%, and the braiding density of the first tin-plated copper braided shielding layer is ≥60%.

[0013] Optionally, the shielded signal wire pair is provided with a second tin-plated copper braided shielding layer on the outside, and the braiding density of the second tin-plated copper braided shielding layer is ≥80%.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] This cable provides dual protection through its outer and inner sheaths. To further prevent rodent gnawing, a first capsaicin anti-bite layer and a second capsaicin anti-bite layer are coated on the surfaces of both sheaths. Considering that the second capsaicin anti-bite layer may be scratched during installation, a groove is created in the middle of the reinforcing ridges. This prevents the second capsaicin anti-bite layer in the groove from being scratched off, ensuring that even if the scratched portion is located within the groove, the second capsaicin anti-bite layer still provides protection.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figures 1 to 7 This utility model provides a technical solution: a signal composite cable, including a power line, a shielded mesh cable, a shielded signal cable and an outer sheath 1. The power line, shielded mesh cable and shielded signal cable are provided inside the outer sheath 1. The power line, shielded mesh cable and shielded signal cable are separated from the outer sheath 1 by an inner sheath 2. The surface of the inner sheath 2 is coated with a first capsaicin anti-bite layer 3.

[0030] Multiple reinforcing protrusions 4 are fixed on the outer surface of the outer sheath 1. Each reinforcing protrusion 4 has an inner groove 5 in the middle. The outer sheath 1, the reinforcing protrusions 4 and the inner groove 5 are coated with a second capsaicin anti-bite layer 6.

[0031] The inner sheath 2 is filled with a heat-insulating filling layer 7 for cable rounding. Considering its multi-functional use and its widespread application in communication engineering, we have found that it is susceptible to being gnawed by rodents, such as rats, during outdoor installations, which affects its performance. This cable provides dual protection by setting an outer sheath 1 and an inner sheath 2. To further prevent rodent gnawing, a first capsaicin anti-bite layer 3 and a second capsaicin anti-bite layer 6 are coated on the surface of the outer sheath 1 and the inner sheath 2, thus preventing rodent gnawing. Considering that the second capsaicin anti-bite layer 6 may be scratched during installation, a groove 5 is opened in the middle of the reinforcing protrusion 4. This prevents the second capsaicin anti-bite layer 6 in the groove 5 from being scratched off, so that even if the scratched part is located in the groove 5, the second capsaicin anti-bite layer 6 can still provide protection.

[0032] The inner core of the power cord is a first pure copper conductor 8, and a first polyethylene insulation layer 9 is wrapped around the outside of the first pure copper conductor 8. A first polyester film 10 is wrapped around the outside of the first polyethylene insulation layer 9. The first polyethylene insulation layer 9 provides insulation for the inner core of the power cord, i.e., the outside of the first pure copper conductor 8. The presence of the first polyester film 10 provides moisture protection for the first polyethylene insulation layer 9 and has excellent heat resistance, preventing high temperature from being transmitted to the inside of the cable.

[0033] The shielded signal wire has a tin-plated copper conductor 11 as its inner core and a second polyethylene insulation layer 12 on the outside of the tin-plated copper conductor 11. Every two shielded signal wires are twisted together to form a shielded signal wire pair. The shielded signal wire pair is wrapped with a second polyester film 13. The second polyethylene insulation layer 12 provides insulation for the tin-plated copper conductor 11. The twisting of the two shielded signal wires allows the magnetic fields generated by the two shielded signal wires during the twisting process to cancel each other out, thereby avoiding mutual interference.

[0034] The inner core of the shielded wire is a second pure copper conductor 14, and a third polyethylene insulation layer 15 is provided on the outside of the second pure copper conductor 14. Every two shielded wires are twisted into a shielded wire pair. The third polyethylene insulation layer 15 provides insulation for the second pure copper conductor 14.

[0035] In this design, every two shielded mesh wires are twisted together to form a cable and wrapped with a third polyester film 16. An aluminum film shielding layer 17 is provided on the outside of the two shielded mesh wires, and a first tin-plated copper braided shielding layer 18 is also provided on the outside of the aluminum film shielding layer 17. The aluminum film coverage is 100%, and the braiding density of the first tin-plated copper braided shielding layer 18 is ≥60%. By setting the aluminum film shielding layer 17 and the first tin-plated copper braided shielding layer 18, the shielded mesh wires are fully shielded, avoiding interference from external signals to the transmitted signals.

[0036] The shielded signal wire pair is provided with a second tinned copper braided shielding layer 19 on the outside, and the braiding density of the second tinned copper braided shielding layer 19 is ≥80%. By setting the second tinned copper braided shielding layer 19, the shielded signal wires are shielded, thus avoiding mutual interference between multiple shielded signal wires.

[0037] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
