This series of split watertight connectors adopts an innovative split-body structure design to realize centralized connection and rapid assembly & disassembly of multi-channel signals or power supplies.One main receptacle can connect multiple independent plugs simultaneously, drastically reducing the number of equipment cutouts and lowering structural leakage risks. Each channel features independent sealing without mutual interference.With compact structure and flexible installation, they are suitable for underwater control systems, multi-sensor integrated platforms, subsea detection arrays and other scenarios with complex wiring layouts, functioning as a miniature distribution hub.
