Description

Technical Field

[0001] The utility model belongs to the technical field of cold shrink sleeves, and in particular relates to a cold shrink sleeve with built-in glue. Background Art

[0002] Cold shrink tubing generally refers to cold shrink cable accessories. Cold shrink cable accessories are made of elastomeric materials (commonly used are silicone rubber and EPDM rubber) that are injection-vulcanized in the factory, and then expanded and lined with plastic spiral supports to form various cable accessory components. However, the existing technology has a slender rope head, which is not convenient for manual pulling out of the rope head.

[0003] Application number "CN202021383096.1" records "a self-fastening cold shrink sleeve, comprising a silicone rubber cold shrink tube and a support, the support is arranged close to the inner tube wall of the silicone rubber cold shrink tube; the support is a hollow structure, the surface of the support in contact with the silicone rubber cold shrink tube is provided with a threaded self-fastening belt, and one end of the self-fastening belt is provided with a tap extending out of the silicone rubber cold shrink tube."

[0004] The above patent is based on a self-clinching cold shrink tubing, which is easy to install, does not require heating, does not require hot melt adhesive or tape to strengthen the seal at the joints, and has uniform seams and consistent force; the expansion ratio is about 4 times, which is suitable for connection seals of different diameters.

[0005] The above patent is easy to install, and can achieve enhanced sealing without heating, hot melt adhesive or tape. It also has the advantages of large shrinkage ratio, excellent physical and mechanical properties, and puncture resistance. 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. However, the device has a long and thin rope end for pulling the supporting core member. If the staff sweats or touches water in their hands, it is very inconvenient to remove the supporting core member. Utility Model Content
