Abstract

The invention relates to a bin penetrating structure of cable sealing. The structure is applied into an underwater propulsion motor. When power electricity or a signal is transmitted to a control driver by a power cable or a control cable of the motor, a medium in the motor and a medium in the control driver can be isolated with each other through connecting the power cable or the control cable inthe motor with the power cable or the control cable in the control driver by the structure, namely, a cable sealing structure under the condition of bin penetrating of a cable from a liquid side to an air side is achieved. The structure is simple, is convenient to install and is reliable in sealing and low in cost, the structure is convenient and flexible to install and use, a copper core is usedfor transferring an electric signal or the power electricity, two ends can employ a welding mode, and connection also can be achieved by a wiring terminal as long as a press nut is pressed; and the structure is high in reliability, materials of an insulation sealing sleeve and an insulation sealing cushion employ polytetrafluoroethylene, insulation is ensured after pressing, and meanwhile, the pressure of 20MPa or above can be borne.

Description

technical field [0001] The invention relates to a cable sealing penetration structure, which is applied to an underwater propulsion motor. When power electricity or signals are transmitted to a control driver through a power cable or a control cable of the motor, the structure is used to protect the motor inside the motor. The power cable or control cable is transferred to the power cable or control cable in the control driver, which can realize the mutual isolation of the medium in the motor and the medium in the control driver, that is, a way to realize the cable passing from the liquid side to the air side Cable sealing structure in cabin case. Background technique [0002] In the design and application of underwater propulsion motors, the integrated design of control drives and motors has received more and more attention due to its advantages of small size, light weight, and low noise. [0003] In the integrated design process of the underwater propulsion motor, in orde...
