The Ethernet line 1 includes a first cable core and a first sheath wrapped around the outer layer of the first cable core. The control line 2 includes a second cable core and a second sheath wrapped around the outer layer of the second cable core; a connecting component 3 is arranged between the Ethernet line 1 and the control line 2, and the connecting component 3 is connected between the first sheath and the second sheath.

[0023] The present utility model provides an Ethernet waterproof cable, which is a high-performance cable designed to meet the requirements of high-speed data transmission, signal control, and waterproofing. The structure adopts a unique flat structure, and the shape design makes it easier to shuttle and connect in narrow spaces. At the same time, separating high-speed data transmission and signal control not only helps to improve data transmission efficiency, but also better manages signal interference and extends the service life of the cable.

[0024] As a preferred embodiment of the present utility model, the first cable core includes a first wire core and a mylar layer 105 wrapping the first wire core. The first wire core includes a first conductor 101 and an aluminum foil partial shielding layer 103 wrapping the first conductor 101. Specifically, the number of the first conductors 101 is 2, and the first conductor 101 further includes a first insulating layer 102 which is wrapped around the outer layer of the first conductor 101; the number of the first wire cores is 2, and a first filler 104 is arranged in the gap within the first cable core.

[0025] The aluminum foil partial shielding layer 103 is wrapped with aluminum foil for shielding after the two first conductors 101 are twisted. It is mainly used to shield high-frequency electromagnetic waves, prevent high-frequency electromagnetic waves from contacting the network cable conductors and thus generating induced current, and increase crosstalk. The repetition rate of the aluminum foil of the network cable using aluminum foil as the shielding layer shall not be less than 20%.

[0026] The mylar layer 105 is arranged to wrap the first wire core. Wrapping a layer of mylar layer 105 before cable braiding can effectively protect the wire core from damage. The main purpose of wrapping the mylar layer 105 is to provide an additional insulation and protection layer to enhance the performance and stability of the cable. At the same time, it has chemical corrosion resistance, which can effectively improve the service life and safety of the cable.

[0027] Specifically, the structure of the first sheath from the inside to the outside is successively an aluminum foil overall shielding layer 106, a first shielding layer 107, a PE sheath 108, a first waterproof tape 109, a first TPU sheath 110, and a first nylon sheath 111.

[0028] The aluminum foil overall shielding layer 106 is wrapped with aluminum foil for overall shielding after the two first wire cores are twisted. The aluminum foil layer, as a shielding layer, can effectively resist external electromagnetic interference. It reduces the influence of electromagnetic waves on the internal signal transmission of the cable through the reflection and absorption of electromagnetic waves. In a strong interference environment, the aluminum foil overall shielding can help maintain the stability of the network signal. It can not only prevent external interference signals from invading, but also prevent the electromagnetic leakage generated inside the cable from affecting other devices or cables.

[0029] The main function of the PE sheath 108 is to protect the insulating layer of the cable from damage. At the same time, it plays a waterproof role. It can prevent the insulating layer from being affected by moisture, mechanical damage, as well as light and chemically erosive media. In addition, the inner sheath can also help the cable pass through the short-circuit current to ensure that the cable can maintain good electrical performance under various usage conditions.

[0030] As a preferred embodiment of the present invention, the second cable core includes a second core and a second waterproof tape 204 wrapping the second core, and the second core includes a second conductor 201 and a second insulating layer 202 wrapping the second conductor 201. Specifically, the number of the second cores is 2, and a second filler 203 is provided in the gap in the second cable core.

[0032] The first TPU sheath 110 and the second TPU sheath 205 are made of TPU sheath, which has excellent mechanical properties, including high strength, high elasticity, high wear resistance and good tear resistance. These properties enable the TPU sheath to protect the network cable from damage by external mechanical forces and improve the durability of the network cable. The TPU material has good weather resistance and chemical resistance and can resist harsh environmental conditions such as sunlight, moisture, grease and other chemicals.

[0033] The first nylon sheath 111 and the second nylon sheath 206 are made of nylon sheaths, so that the cable has excellent oil resistance, wear resistance, fire resistance, cold resistance, high temperature resistance and waterproof performance.

[0034] Specifically, the first conductor 101 and the second conductor 201 are Category VI tinned copper conductors, which are formed by twisting multiple strands of tinned copper wires; the first insulation layer 102 is a foamed PE layer, and the second insulation layer 202 is a cross-linked polyolefin insulation layer; the first filler 104 and the second filler 203 are waterproof filling ropes.

[0035] The first conductor 101 and the second conductor 201 use Category VI tinned copper wires, which are twisted together with multiple strands of tinned copper wires and have good bending properties. Tinned copper has good electrical conductivity; the surface coating of tinned copper can prevent copper oxidation, improve its anti-corrosion performance, and has good mechanical properties and can withstand various physical impacts and wear.

[0036] The first insulating layer 102 is made of foamed PE. The advantages of foamed PE insulation material include making the product lightweight, reducing costs, improving thermal insulation and flexibility, being waterproof and moisture-proof, and having excellent high-frequency attenuation performance and environmental stress cracking resistance.

[0037] The second insulating layer 202 uses cross-linked polyolefin insulation material. Cross-linked polyolefin insulation is a new type of environmentally friendly material with the characteristics of high temperature resistance, halogen-free, low smoke, flame retardancy, etc. It has good heat resistance and radiation resistance and a longer service life.

[0038] The first filler 104 and the second filler 203 adopt waterproof filling ropes. The waterproof filling ropes fill the gaps inside the cable, preventing moisture and other harmful substances from entering the cable, thereby protecting the cable from damage. The waterproof filling ropes can improve the flexibility and tensile resistance of the cable and extend the service life of the cable.

[0039] Specifically, the first shielding layer 107 is a braided shielding layer made of tinned copper wires, and the braiding density is ≥80%; both the first waterproof tape 109 and the second waterproof tape 204 are single-layer waterproof tapes.

[0040] The first shielding layer 107 is a braided shielding layer, which is braided and shielded with tinned copper wires, and the braiding density is ≥80%. It is mainly used to prevent electrostatic interference, electromagnetic induction, crosstalk induction and interference generated by other signal lines in the energy storage system, ensuring the normal operation of system transmission.

[0041] The first waterproof tape 109 is wrapped around the PE sheath 108 with a waterproof tape. The most important function is to prevent moisture from invading and protect the internal structure of the network cable from water damage. Moisture invading the network cable may cause short circuits or other electrical faults, affecting the transmission of network signals. Using the waterproof tape can improve the stability of the network, avoid faults caused by moisture, and ensure the reliable transmission of network signals.

[0042] The second waterproof tape 204 is wrapped around the second TPU sheath 205 with a waterproof tape. Its main function is to protect the cable from moisture and other harmful substances during the use of the cable, thereby improving the water resistance and corrosion resistance of the cable. The waterproof tape has good flexibility and adaptability and can tightly wrap around the cable surface to prevent moisture penetration.

[0043] Specifically, the connecting component 3 connects the first TPU sheath 110 and the second TPU sheath 205, and the connecting component 3 is a TPU connecting component.

[0044] The cable of the present utility model is a high-performance cable that can provide an efficient, stable and secure data transmission solution while meeting high-speed data transmission and signal control. This solution can not only meet the requirements of high-speed data transmission but also achieve precise control and management of data, and is an important part of modern information technology. Its unique structure and superior performance enable it to be widely used in fields such as the automotive industry, industrial automation, robotics, the aviation industry, and the shipbuilding industry. In future development, the high-speed Ethernet waterproof cable will continue to play an important role in promoting the development and technological progress of related industries. With the continuous development of technology, we can expect this technology to become more mature and advanced, bringing greater impetus to the development of human society.

[0046] 1. Unique flat structure

[0047] The shape design makes it easier to shuttle and connect in narrow spaces.

[0049] This cable is designed for simultaneous high-speed data transmission and signal control. The synergistic effect between them can bring more efficient data management. In addition, this simultaneous feature can also improve the reliability and stability of the network, and has specific advantages in handling large amounts of data and high loads.

[0050] 3. Waterproof performance

[0051] The waterproof layer and wrapping layer of the cable provide double waterproof protection. At the same time, the outer sheath of the cable uses an outer sheath of nylon material to strengthen the waterproof function and ensure that the cable can still work properly in a humid environment.

[0052] 4. Anti-interference ability

[0053] The design of the multi-layer shielding layer effectively reduces electromagnetic interference and improves the stability and quality of the signal.
