Description

Technical Field

[0001] The utility model relates to the field of PVC cable protection tubes, in particular to a self-sealing interface of a PVC cable protection tube. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are capable of transmitting electricity or information from one location to another. Cables are expensive to manufacture and are easily damaged. Therefore, cables are typically installed with a protective tube. This tube is applied to the outer layer of the cable to prevent damage and extend its service life. However, existing cable tubes are simple in structure and difficult to connect and install. They cannot be directly installed or disassembled between pipes, resulting in low installation efficiency. Furthermore, the lack of a structured wiring allows for easy tangling during threading. Therefore, a self-sealing interface for PVC cable tubes has been proposed. Utility Model Content
