Description

Technical Field

[0001] The utility model relates to the field of silicone wires, in particular to a 4K high-definition endoscope high-temperature resistant silicone wire. Background Art

[0002] The silicone high-temperature wire currently in use is made of silicone rubber and high-purity tinned copper stranded wire, such as the patent number CN219303375U that discloses a high-temperature resistant silicone wire. The high-temperature resistant silicone wire includes a wire core, a high-temperature resistant layer and a silicone layer. The surface of the wire core is provided with an insulating layer, the surface of the insulating layer is provided with an inner lining layer, the high-temperature resistant layer is coated on the surface of the inner lining layer, the silicone layer is provided on the outside of the high-temperature resistant layer, and a pressure-resistant layer is provided between the silicone layer and the high-temperature resistant layer. The high-temperature resistant layer includes an asbestos fiber layer and a glass fiber layer, an isolation layer is provided between the asbestos fiber layer and the glass fiber layer, the asbestos fiber layer is coated on the surface of the insulating layer, and the glass fiber layer is coated on the surface of the isolation layer.

[0003] The existing silicone wire has all the cores located in the middle, which makes the anti-interference performance between the cores poor. Ultimately, when used with a medical endoscope, the endoscope cable has poor conduction and anti-interference performance, and the image cannot meet high-definition transmission. For this reason, we propose a 4K high-definition endoscope high-temperature resistant silicone wire. Utility Model Content
