Description

Technical Field

[0001] The utility model belongs to the technical field of cold shrinkable sleeves, and particularly relates to an anti-slip and sealed cold shrinkable sleeve. Background Technique

[0002] Cold shrinkable sleeves generally refer to cold shrinkable cable accessories. Cold shrinkable cable accessories are made by injecting and vulcanizing elastomer materials (commonly used are silicone rubber and ethylene propylene rubber) in the factory, and then expanding the diameter and lining with plastic spiral supports to form various components of cable accessories. During on-site installation, these pre-expanded sleeves are put on the processed cable ends or joints, and the internal supporting plastic spiral strips (supports) are pulled out and pressed on the cable insulation to form cable accessories. Because it relies on elastic retraction force at normal temperature, rather than using fire heating for shrinkage like heat shrinkable cable accessories, it is commonly known as cold shrinkable cable accessories.

[0003] The authorized publication number "CN212380924U" records "a self-locking cold shrinkable sleeve, including a silicone rubber cold shrinkable tube and a support. The support is arranged closely against the inner tube wall of the silicone rubber cold shrinkable tube; the support is of a hollow structure, and the surface of the support in contact with the silicone rubber cold shrinkable tube is provided with a thread-shaped self-locking belt, and one end of the self-locking belt is provided with a tap extending out of the silicone rubber cold shrinkable tube. The utility model has the advantages of simple installation, no need for heating, no need for hot melt adhesive or tape to achieve enhanced sealing, large shrinkage ratio, excellent physical and mechanical properties, puncture resistance, etc., and is suitable for waterproof and moisture-proof sealing of communication and cable TV connection joints, insulation sealing of wire and cable connections, and insulation protection of other types of connectors, etc."

[0004] The above-mentioned new self-locking cold shrinkable sleeve has the advantages of large shrinkage ratio, excellent physical and mechanical properties, puncture resistance, etc. It is suitable for waterproof and moisture-proof sealing of communication and cable TV connection joints, insulation sealing of wire and cable connections, and insulation protection of other types of connectors, etc. However, in the actual use process, after the support in the cold shrinkable sleeve is extracted, although the cold shrinkable sleeve is closely attached to the circumferential surface of the cable, the friction force between the cold shrinkable sleeve and the circumferential surface of the cable decreases after being immersed in liquid, resulting in a rapid decline in the anti-slip and sealing ability of the cold shrinkable sleeve. Therefore, we propose an anti-slip and sealed cold shrinkable sleeve. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-slip and sealed cold shrinkable sleeve, aiming to solve the problem that after the support in the cold shrinkable sleeve is extracted, although the cold shrinkable sleeve is closely attached to the circumferential surface of the cable, the friction force between the cold shrinkable sleeve and the circumferential surface of the cable decreases after being immersed in liquid, resulting in a rapid decline in the anti-slip and sealing ability of the cold shrinkable sleeve.
