Abstract

The invention relates to a coaxial underwater sealed connector suitable for underwater operation, which comprises a coaxial socket and a coaxial plug, wherein the front end of the shell of coaxial plug is provided with a boss and the front end of the shell of the coaxial socket is provided with a recess; the boss and the recess correspond in position, and the rear end of the shell of the coaxial plug is provided with an O-shaped sealing ring. The connector can meet a preset resistance to transmit radio signals under severe sea condition and can resist seawater corrosion. The connector is a novel underwater product which can be used in both shallow and deep sea. The connection is suitable to be used on various kinds of underwater operation equipment, underwater robots (ROV) and autonomous underwater vehicles (AUV) to transmit the radio signals. The connector has the characteristics of excellent underwater seal reliability, suitability for underwater radio signal transmission, capabilityof meeting preset resistance property, insulating resistance of more than 200 to 300 Momega and contact resistance of less than 0.01 Omega for operation at a depth of 0 to 1,500 meters underwater, and capability of being inserted and pulled out for more than or equal to 500 times.

Description

technical field [0001] The invention relates to a coaxial watertight connector, in particular to a coaxial watertight connector used in underwater operations. Background technique [0002] With the increasing application of underwater robots (ROV) and underwater self-propelled vehicles (AUV), the demand for coaxial connectors is becoming more and more urgent, because coaxial connectors can meet the requirements of harsh sea conditions. The transmission of radio signals requires strict sealing technology. Existing coaxial connectors have the following problems: [0003] ① Only suitable for transmitting radio signals on land; [0004] ② No underwater sealing measures; [0005] ③ Not suitable for underwater radio signal transmission; Contents of the invention [0006] In order to solve the above technical problems, the object of the present invention is to provide a coaxial connector that can meet the transmission of radio signals under harsh sea conditions and can be str...
