Described socket and plug body adopt rubber curing forming; Needle stand evenly distributes in plug body in the described plug; Contact pin evenly distributes in socket in the described socket; The number of described contact pin and needle stand can be decided as required, is generally 3～6.
The utlity model has following advantage:
1. applied range.The utility model not only is used for deep water, also is applicable to shallow water, can be used as obtaining of submerged pipeline cathodic protection electric field data, reaches metal structures and other required occasions of carrying out the Underwater Electric Potential detection such as boats and ships, naval vessels, harbour piling bar, oil platform.
2. combination property is steady.The utility model connector under water can keep permanent sealing in 0～300 meter seawater or fresh water, have weather-resistant, anti-biodeterioration performance, and acid and alkali resistance, salt and salt fog, and oil resistant and chemical resistance are good, and temperature range is at-10 ℃～50 ℃.
3. good electrical properties.Contact resistance is less than 0.01 ohm in 0～300 meter under water for the utility model, and the contact rated capacity is 100～220V/5～10A, and the plug number of times can reach more than 500 times.
4. practical.The utility model can use under any waters, and directly plug-in can be with water cutting to pull out, installation, convenient disassembly, and volume is little, in light weight, high pressure resistant, watertightness is good, can be used as to connect on the underwater cathode protection electric field checkout equipment to use.
