Description
Technical field
The utility model relates to a kind of plug, relates in particular to a kind of submersible type plug peculiar to vessel, belongs to electrical equipment manufacturing technology field.
Background technology
Submersible type plug is mainly used in for light signal instrument, anchor lantern and color lamp etc., providing power supply outward for pressure hull, to guarantee that naval vessel under any circumstance can both provide power supply to meet signalling arrangement instructions for use reliably, fast timely, guarantee that naval vessel is in the safe and reliable navigation of the water surface.
As everyone knows, when naval vessel rides the sea, maritime environment is more severe, and wetness is larger, and salt air corrosion ability is strong, therefore, this just to naval vessel on the plug used require relatively high.
The plug using on naval vessel is at present the seventies product, and the degree of protection of its housing is labeled as water-tight type IP68, but its actual barrier propterty is only IP23 left and right after using 1 year.The upper regulation degree of protection of GJB GJB4000-2000 is water-tight type pattern, and application place---can only be that surface vessel underwater is likely buried the place of working under water, test requirements document be that test product is immersed in the water, immersed depth 10m, time 30min; Or envelope filledly with 25～50kPa air, last 5～30min, and should discharge without bubble, this is under the condition such as design concept, technological level and material be at that time supporting, leading at last.From above-mentioned, know, this water-tight type plug is to be discontented with instructions for use on the sea water advanced submarine of 450m of can diving completely completely.This has had a strong impact on the system safety of shipboard power system, even can have influence on the safety of ship and carry out completing of combat mission.Therefore need to develop a kind of submersible type plug, to meet the Special use environmental requirement on naval vessel.
Utility model content
For above-mentioned defect, it is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, the submersible type plug a kind of peculiar to vessel that good waterproof performance and corrosion resistance are strong.
The technical scheme that the utility model adopts is for this reason: comprise housing, described housing lower end side is provided with a tube connector, in described tube connector, be provided with step place, from step in tube connector, be outwards provided with successively metal washer, rubber washer, metal washer and interface, in housing, upper end is provided with plug-assembly, and the radial space of described plug-assembly and housing is provided with cock.
The external screw thread being provided with in described tube connector on internal thread and interface external diameter is in mating connection.
Described housing and tube connector are integral type, and form by brass casting.
The utility model has the advantages that: the utility model is simple in structure, easy to use, good waterproof performance and rotproofness are strong.
