[0002] Chinese Patent CN107799980B discloses a cable sealing structure for underwater propulsion motors. This structure, applied to underwater propulsion motors, allows for the transfer of power or signal transmission between the motor and control drivers via their respective power or control cables. This achieves mutual isolation between the media within the motor and the control driver, effectively sealing the cable when it passes through the air chamber from the liquid side. The structure is simple, easy to install, provides reliable sealing, and is low-cost. The invention offers convenient and flexible installation and use. The copper core transmits electrical signals or power, and the two ends can be connected by welding or terminal blocks, ensuring the compression nuts are tightened. It boasts high reliability; the insulating sealing sleeve and gasket are made of polytetrafluoroethylene (PTFE), which, after compression, ensures insulation while withstanding pressures exceeding 20 MPa.
