Description

Technical Field

[0001] The utility model belongs to the technical field of communication engineering, and in particular relates to a built-in adhesive cold shrink sleeve for communication engineering antenna feed equipment. 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 and molded in the factory, and then expanded and lined with plastic spiral supports to form various cable accessories. Cold shrink tubing is mainly used in the installation of antenna feed equipment in wireless network communication projects. The cold shrink tubing is pre-expanded on a removable core rope. It is easy to operate. You only need to locate it at the installation site and pull out the core rope. However, in the existing technology, when the communication line connector is connected and the plastic spiral strip is pulled out, the glue itself will adhere to the plastic spiral strip, so it is easy to bring out the glue. The glue brought out will make the sealing between the rubber sleeve and the communication connector poor, causing the screws to rust.

[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 self-fastening 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 joint, and has uniform joints and consistent strength; the expansion ratio is about 4 times, suitable for connection sealing of different diameters; it 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.

[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, when the communication line connector is docked and the plastic spiral strip is pulled out, the glue itself will adhere to the plastic spiral strip, so it is easy to bring out the glue. The glue being brought out will make the sealing between the rubber sleeve and the communication connector poor, causing the screws to rust. Utility Model Content
