Description

Technical Field

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

[0002] Cold shrink tubing is a component of various communication connector accessories that is formed by injection vulcanization of elastomeric materials (commonly used are silicone rubber and EPDM rubber), and then expanded and lined with plastic spiral supports. During on-site installation, these pre-expanded parts are put on the treated end or joint of the communication connector, and the internal supporting plastic spiral strips (supports) are pulled out and pressed against the communication connector to form a communication connector accessory. Because it relies on elastic retraction force at room temperature, rather than heat shrinking communication connector accessories that require fire to shrink, it is commonly known as cold shrink communication connector accessories. However, the existing technology cannot adjust the overall length of the cold shrink tubing according to on-site needs, resulting in large limitations for the cold shrink tubing.

[0003] Application number "CN201920060862.1" records "a high-sealability cold shrink sleeve, comprising a plastic spiral strip, a clay layer and a rubber sleeve layer arranged in sequence from the inside to the outside, a lubricant layer is arranged between the plastic spiral strip and the clay layer, a first frosted layer is arranged between the clay layer and the rubber sleeve layer, a second frosted layer is arranged on the outer wall of the rubber sleeve layer, a plurality of annular grooves for accommodating the clay are arranged on the inner wall of the rubber sleeve layer, the plurality of annular grooves are arranged at equal intervals, the clay layer is arranged at both ends of the rubber sleeve layer, the clay layer forms a blank section in the middle of the rubber sleeve layer, and reinforcing ribs are arranged on the outer wall of the rubber sleeve layer at both ends corresponding to the clay layer."

[0004] The above patent is based on a high-sealability cold shrink sleeve. A first frosted layer is provided between the mastic layer and the rubber sleeve. The first frosted layer has the advantage of increasing the friction between the mastic layer and the rubber sleeve, so that the mastic layer is not easy to separate from the rubber sleeve. A second frosted layer is provided on the outer wall of the rubber sleeve. The second frosted layer facilitates the operator to hold the rubber sleeve tightly to install the communication connector during the installation operation, even if dust falls on the surface of the rubber sleeve. The inner wall of the rubber sleeve is provided with a plurality of annular grooves for accommodating mastic. The advantage of such a setting is that the rubber sleeve has a multi-layer sealing ring inside, so that the sealing is further enhanced.

[0005] The above patent can ensure sealing and anti-slip, but the device has a strict limit on the length of the cold shrink sleeve, and cannot adjust the length of the cold shrink sleeve according to the on-site length requirements, resulting in greater limitations of the cold shrink sleeve.
