Problems solved by technology

The current underwater connectors use the principle of contact transmission, which squeezes out the moisture in the socket and pins to achieve a leak-free underwater electrical connection. However, it is used in deep-sea environments. It has exposed many shortcomings such as difficult plugging and unplugging operations, limited number of uses, and potential safety hazards.
The above shortcomings can be overcome by using the non-contact principle. However, due to the limitation of the non-contact principle, the transmission efficiency and transmission rate usually cannot reach the level of the contact principle.

Abstract

The invention discloses an underwater signal electrical-coupling non-contact type bi-directional transmission connector, which comprises two parts, namely a plug and a socket. The plug and the socket are two independent waterproof and pressure-resistant cavities. Circuit elements are arranged in the cavities. The plug and the socket are interchangeable and are respectively connected with an electric energy and signal receiving device and an electric energy and signal sending device. During operation, the plug and the socket approach each other, and the electric energy and signals are transmitted between the receiving device and the sending device via the connector. The input electric energy and the output electric energy can be a direct current (DC) or an alternating current (AC). The transmission of the electric energy and signals is conducted based on the basic principles of electromagnetic induction. The high-frequency carrier of a signal is injected into the AC carrier of the transmitted electric energy, transmitted to the other end via a coupling coil and then extracted at the other end. The transmission frequency of the electric energy and the harmonic compensation capacitance value of a transmission module can be adjusted in real time via the signal, so that the transmission efficiency is always in the highest state. The connector can be applied in any sea of any water depth, and is stable in operation, long in service life and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of deep-sea telecommunications transmission, and relates to an underwater connector, in particular to an underwater telecommunications coupling non-contact bidirectional transmission connector. Background technique [0002] With the continuous deepening of people's observation of the seabed, the use of underwater equipment is becoming more and more extensive. [0003] There are complex and close interconnections between underwater equipment, and frequent mutual power transmission and signal communication are required. When underwater equipment needs to transmit power and signals, it needs to be connected by physical lines, and when these physical lines are connected to each other or to equipment, it is necessary to widely use a "plug and socket" with functions similar to those used on land. Underwater Connector". [0004] Power and signal transmission can be divided into two basic principles: contact and n...
