Description

Technical Field

[0001] The utility model belongs to the technical field of sealing of protective equipment, and in particular relates to a spherical protective cover device with a multiple waterproof sealing structure. Background Art

[0002] Shipborne electronic equipment serves in a harsh marine climate environment. High temperature, high humidity, corrosive substances in the air, salt spray and various molds are extremely destructive to the equipment, directly affecting the changes in parameters such as conductivity, magnetic permeability, inductance, capacitance, electronic emission and electromagnetic shielding of the equipment. Therefore, during the use of ship communication equipment, some communication equipment needs special protection. The protective equipment currently used is generally iron boxes or waterproof cloth wrapped around them.
