Although such watertight cables reduce the difficulty of design and production, they require multiple assembly and sealing during use, which increases the assembly difficulty of watertight cables, reduces the assembly efficiency of components, and greatly increases the risk of sealing quality problems of components. Furthermore, existing watertight cables cannot fully cover optical transmission, radio frequency signal transmission, data signal transmission, and high current transmission functions.
