Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically a double-shielded data cable. Background Technology

[0002] With the development of communication technology, the application fields of data cables are becoming increasingly wider, and the environmental adaptability requirements for data cables are also becoming increasingly stringent. Currently, double-shielded data cables are mainly used in densely wired areas such as data centers and computer rooms. When this data cable is used for data transmission, the data signal is sent through a signal transmitter according to a certain encoding method. Using the data cable as a medium, the signal is transmitted to the receiver or terminal, and then converted into a usable signal source by a decoder.

[0003] Existing double-shielded data cables have poor compressive strength and waterproof performance, making it difficult to effectively protect the core wires. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a double-shielded data cable to address the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A double-shielded data cable includes, from the inside out, a reinforcing core, a core support, a core, an inner sheath, an outer shielding layer, and an outer sheath. The core support includes a sleeve and support plates. Multiple support plates are evenly arranged radially on the outer side of the sleeve, with each support plate arranged along the axis of the sleeve. A reinforcing core is arranged at the axis inside the sleeve. An inner sheath is arranged on the outer side of the core support. An independent chamber is formed between two adjacent support plates and the inner sheath. A core is placed in the independent chamber, and the independent chamber is also filled with cotton or linen fibers. Each core is covered by an inner shielding layer. An outer shielding layer is covered on the outer side of the inner sheath. An armor layer is covered on the outer side of the outer shielding layer. A waterproof layer is covered on the outer side of the armor layer. An outer sheath is covered on the outer side of the waterproof layer.

[0007] Furthermore, the core support is made of silicone rubber.

[0008] Furthermore, the inner shielding layer is a conductive foam wrapping layer.

[0009] Furthermore, the outer shielding layer is a braided copper strip wrapping layer, and a waterproof coating layer is provided between the outer shielding layer and the armor layer. The waterproof coating layer is made of polyvinyl chloride waterproof coating.

[0010] Furthermore, the waterproof layer is a water-blocking tape wrapping layer.

[0011] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0012] This invention, through the design of a core support, a waterproof layer, a waterproof coating layer, inner / outer shielding layers, and an armor layer, enables the cable to possess excellent compressive strength and waterproof performance. The core support, made of silicone rubber, not only possesses good flexibility and durability but also provides additional buffering and protection between the core and the inner sheath. By incorporating a reinforcing core at the cable axis and adding an armor layer outside the outer shielding layer, the overall compressive strength of the cable is enhanced. The PVC waterproof coating also has good elasticity and provides a certain degree of buffering. The waterproof layer and the waterproof coating layer work together to form multiple waterproof barriers, effectively preventing moisture from penetrating the cable and ensuring stable data signal transmission in humid environments. The inner and outer shielding layers effectively reduce electromagnetic interference and signal loss, improving the data cable's anti-interference capability and signal transmission quality. In particular, the inner shielding layer uses a conductive foam wrapping structure, which better conforms to the core and provides a uniform shielding effect.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0020] like Figure 1-2As shown, a double-shielded data cable includes, from the inside out, a reinforcing core 3, a core support 1, a core 2, an inner sheath 5, an outer shielding layer 6, and an outer sheath 7. The core support 1 includes a sleeve and support plates. Multiple support plates are evenly arranged radially on the outer side of the sleeve, and each support plate is arranged along the axis of the sleeve. A reinforcing core 3 is arranged at the axis inside the sleeve. An inner sheath 5 is arranged on the outer side of the core support 1. An independent chamber is formed between two adjacent support plates and the inner sheath 5. The core 2 is placed in the independent chamber, and the independent chamber is also filled with cotton and linen fibers 10. Each core 2 is covered with an inner shielding layer 4. The outer shielding layer 6 is covered on the outer side of the inner sheath 5. An armor layer 8 is covered on the outer side of the outer shielding layer 6. A waterproof layer 9 is covered on the outer side of the armor layer 8. The outer sheath 7 is covered on the outer side of the waterproof layer 9.

[0021] In one embodiment, the core support 1 is made of silicone rubber.

[0022] In one embodiment, the inner shielding layer 4 is a conductive foam wrapping layer.

[0023] In one embodiment, the outer shielding layer 6 is a braided copper strip wrapping layer, and a waterproof coating layer 11 is also provided between the outer shielding layer 6 and the armor layer 8. The waterproof coating layer 11 is made of polyvinyl chloride waterproof coating.

[0024] In one embodiment, the waterproof layer 9 is a water-blocking tape wrapping layer.

[0025] The working principle of this utility model is as follows: The inner shielding layer 4 and the outer shielding layer 6 together form a double-layer shielding structure, effectively blocking the intrusion of external electromagnetic interference and preventing internal signals from radiating outwards and interfering with other equipment. The inner shielding layer 4 is tightly fitted to the conductor 2, providing a uniform shielding effect; the outer shielding layer 6 further enhances the shielding performance of the cable, ensuring the integrity and quality of the signal during transmission. The reinforcing core 3 and the armor layer 8 together enhance the cable's compressive strength, enabling it to resist external pressure and protect the conductor 2 from damage. The waterproof layer 9, including the water-blocking tape wrapping layer and the waterproof coating layer 11, forms multiple waterproof barriers, effectively preventing moisture from seeping into the cable and ensuring stable transmission of data signals in humid environments. The conductor support 1 is made of silicone rubber, which has good flexibility and durability, providing additional buffering and protection between the conductor 2 and the inner sheath 5.
