Marine multilayer integrated USB electric connector

The invention discloses a marine multilayer integrated USB electric connector, and relates to the technical field of electric connectors, the marine multilayer integrated USB electric connector comprises a waterproof side plate, the surface of the waterproof side plate is provided with a transverse notch, and the bottom of the transverse notch is provided with electric connector assemblies at equal intervals. A small amount of water vapor enters and adheres to the interior of the terminal of the USB electric connector, so that the problem that the multi-layer integrated USB electric connector is rusted due to accumulated water vapor after being used for many times cannot be avoided, the overall service life is guaranteed, and meanwhile, under the cooperation of the electric connector assembly, the electric connector assembly is not damaged. According to the utility model, the electromagnetism which cannot be shielded can be timely guided to the electromagnetism eliminator through the electromagnetism conducti
