Description

Technical Field

[0001] The utility model relates to the technical field of cables, and in particular to a sealed high-speed transmission cable. Background Art

[0002] In the era of information development, the development and use of various types of electronic products and new technologies have led to higher demands on transmission cables. As the demand increases, the more structures and materials are added to the cables, the larger the space the cables occupy. Common cables have multiple core wires twisted together with insulators, then wrapped with aluminum foil and insulation, then wrapped with a metal braided mesh, and finally wrapped with an outer sheath. The process is relatively complicated and occupies a large space.

[0003] A patent application with publication number CN205039008U discloses an ultra-high-speed transmission cable, which changes the original half-duplex transmission mode to a full-duplex transmission mode, greatly improving data transmission efficiency; by strengthening the winding shielding layer and the copper foil shielding layer, it can effectively prevent mutual interference between the signals transmitted by each signal line; by setting fillers, the cable has better bending and impact resistance; at the same time, the gaps are filled to ensure the roundness and beauty of the wire.

[0004] Adding multiple layers of shielding layers and fillers in the middle of the above-mentioned cable makes the space of the entire cable larger, occupies more space and becomes heavier, and the manufacturing process is also relatively complicated. Utility Model Content

[0005] The utility model aims to provide a sealed high-speed transmission cable to solve the problems in the above background that the cable has a complex internal structure, a relatively complex manufacturing process and occupies a large space.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A sealed high-speed transmission cable comprises a signal core wire, which is a single-strand core wire and includes two signal core wires. The outer surfaces of the signal core wires are wrapped with insulators. The outer walls of the insulators are provided with grounding wires, which are tangent to the same side of the two insulators. The outer surfaces of the insulators are wrapped with aluminum foil, the grounding wires are inside the aluminum foil, and the outer surface of the aluminum foil is wrapped with an outer sheath, which is elliptical.

[0008] As a further solution of the utility model: the two signal core wires are placed in parallel.

[0009] The beneficial effects of the utility model are as follows: by placing two single-strand signal core wires in parallel and wrapping the outer surface with aluminum foil and an elliptical outer sheath, good sealing and high insulation are achieved while improving resistance to environmental corrosion, saving the complexity of the internal structure without affecting the use of the signal core wire, making the manufacturing process simple, saving a large amount of occupied space under the condition of equal working performance, reducing costs, making high-speed performance more superior, and being able to meet the requirements of higher-speed signal transmission.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figures 1 to 3 As shown, the utility model is a sealed high-speed transmission cable, including a signal core wire 1, which is a single-strand core wire, and the transmission cable has two single-strand signal core wires 1 placed in parallel, and an insulator 2 is wrapped on the outer surface of the signal core wire 1, and the insulator 2 is used to support and separate the two signal core wires 1. The outside of the insulator 2 is wrapped with aluminum foil 4, and the aluminum foil 4 has good sealing performance, light weight and is not easy to be corroded. It can not only well preserve the internal signal core wire 1, but also reduce the weight of the cable, which is convenient for outdoor use. A grounding wire 3 is installed between the aluminum foil 4 and the insulator to conduct current to the ground to prevent leakage. An elliptical outer sheath 5 is wrapped on the outer surface of the aluminum foil 4. The elliptical outer sheath 5 has good sealing performance, insulation and improved environmental corrosion resistance, saves the complexity of the internal structure and does not affect the use of the signal core wire 1. Under the same working performance, the bare wire application space can be saved by more than 50%, which reduces the cost, has better high-speed performance, and can meet the requirements of higher-speed signal transmission.

[0017] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
