Abstract

Wet-mateable connectors enabling power and communication for underwater equipment are greatly favored for underwater systems. However, conventional underwater wet-mateable connectors with electrical contact conductors have the features of high cost, limited mate/de-mate times, and high risk of ground faults when being applied underwater, which limits their used. In this paper, a contactless underwater wet-mateable connector with bowl-shaped couplers was proposed, and an equivalent circuit for inductive power transmission was modeled and analyzed. Then the mathematical expression of the magnetic induction intensity of the bowl-shaped coil was derived. The parameters including ρco, zco, and s0 of the coil were analyzed and optimized to attain better performance and lower cost. A prototype was built and tested. Results showed that it can transmit power up to 1125 W with an efficiency of 85%. In addition, it can achieve a data rate up to 6 MB/s under a water pressure of 20 MPa.
