[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0016] Example

[0017] To address the aforementioned technical problems, this embodiment provides a medical high-swing HDMI video connection cable, such as... Figure 1-2As shown, the device includes a filler 20, several signal wire pairs 10 surrounding the filler 20, several electronic wires 30, and a shielding layer 40, a braided layer 50, and an outer sheath 60 sequentially covering the outer layer. A first ground wire 70 is provided inside the shielding layer 40. The signal wire pairs 10 include at least two twisted core wires 11, a second ground wire 12 located on one side of the core wires 11, and a sheathing layer 13 covering the core wires 11 and the second ground wires 12. The core wires 11 include a first conductor 111 formed by twisting 19 copper wires, and a sheathing layer 13 covering the first conductor. The first insulation layer 112 of 111 and the second ground wire 12 include a second conductor 121 made of 19 copper wires twisted together, a nylon filament 122 disposed in the center of the second conductor 121, and a second insulation layer 123 covering the second conductor 121. This enhances the flexibility of the signal wire pair 10. While meeting the high-frequency electrical performance requirements of the wire, it can enhance the tensile strength of the core conductor, thereby improving the tensile strength of the signal wire pair and increasing the number of swing tests of the overall wire, thus meeting the high swing test requirements and the requirements of the customer terminal medical B-ultrasound equipment.

[0018] Specifically, the covering layer 13 includes an aluminum foil layer 131 wrapped around the core wire 11 and the second ground wire 12, and a self-adhesive polyester tape 132 wrapped around the aluminum foil layer 131. After the two core wires 11 and the second ground wire 12 are twisted together, they are wrapped around the aluminum foil layer 131, which shields the core wires 11 and prevents signal interference between the internal electronic wires 30 and the core wires 11. The self-adhesive polyester tape 132 is used to wrap and fix the aluminum foil layer 131 and the core wires 11, thereby improving the structural stability.

[0019] Furthermore, such as Figure 3 As shown, the electronic wire 30 consists of a third conductor 31 made of 19 stranded copper wires and a PE insulation layer 32 covering the third conductor 31. The PE insulation layer 32 is made of high-density PE material, and the first insulation layer 112 is a PE foam layer. The third conductor 31, made of 19 stranded copper wires, has good flexibility and tensile strength.

[0020] Furthermore, the shielding layer 40 is made of aluminum foil. The braided layer 50 is made of 16 spindles of metal conductors, each spindle consisting of multiple monofilament conductors and a nylon filament twisted together, thereby enhancing the tensile strength of the braided layer and meeting the physical test requirements for high swing resistance. The test conditions are: 500g load, + / -90°, 20 cycles / min, R = 15mm, ≥10000.

[0021] This embodiment includes 5 sets of signal wire pairs 10 and 4 electronic wires 30. Each electronic wire 30 is distributed between two adjacent sets of signal wire pairs 10. A first ground wire 70 is disposed between two sets of signal wire pairs 10 and is in contact with the shielding layer 40. When assembling the cable, the 5 sets of signal wire pairs 10, 4 electronic wires 30, first ground wire 70, and filler 20 are twisted together and then wrapped around the shielding layer 40. When assembling the semi-finished product, a de-twisting method is used to eliminate the twisting internal stress formed by the final assembly. While meeting the requirements of high-frequency performance testing and high swing test physical performance, the overall feel of the cable is also softer.

[0022] In summary, the solution of this application enhances the flexibility of the signal wire pairs by setting up a filler, several signal wire pairs surrounding the filler, several electronic wires, and a shielding layer, a braided layer, and an outer sheath layer sequentially covering the outer layer. A first ground wire is set inside the shielding layer. The signal wire pairs include at least two twisted core wires, a second ground wire located on one side of the core wires, and a sheath covering the core wires and the second ground wires. The core wires include a first conductor made of 19 copper wires twisted together and a first insulation layer covering the first conductor. The second ground wires include a second conductor made of 19 copper wires twisted together, a nylon filament located in the center of the second conductor, and a second insulation layer covering the second conductor. This enhances the flexibility of the signal wire pairs, meets the high-frequency electrical performance requirements of the wire, and enhances the tensile strength of the core wire conductors, thereby improving the tensile strength of the signal wire pairs and increasing the number of swing tests of the overall wire.

[0023] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
