Description

Technical Field

[0002] Silicone tubes are carriers for the circulation and coating of liquids, gases and other materials. In the industry, silicone rubber tubes can be divided into "extruded tubes" and "special-shaped tube strips". They are widely used in modern industry, national defense industry and daily necessities. For example, in the wiring harness of home appliances, it is generally necessary to use wiring harness silicone sleeves to protect the wiring harness of home appliances. Silicone tubes are made by adding silicone rubber raw rubber to a double-roll rubber mixer or a closed kneading machine, and gradually adding white carbon black and other additives to repeatedly refine them evenly. According to the requirements of industry product technical standards, products are made by extrusion. Conductive silicone rubber can be used in the electronics industry. In order to avoid the wiring harness being exposed to the outside world, it is easy to cause the insulation layer to be scratched and damaged, so that the wires are directly exposed, so it is necessary to wrap the outside of the wiring harness with silicone sleeves.

[0003] The current silicone sleeves are generally single-layer silicone tubes with a very simple structure. They do not provide good protection for household wiring harnesses. After the household wiring harnesses pass through the silicone tubes, the wiring harnesses are still easily entangled, and lack the positioning effect for the household wiring harnesses.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
