On the premise of meeting the requirements of water resistance and sealing, the mountable cable has less outer diameter specifications or only has the same outer diameter. 4. The threading pipe both ends need to process the end in order to reach waterproof, sealed requirement, and the process is troublesome and consuming time. Accordingly, there is a need for an improved technique to solve the above-mentioned problems in the prior art.
