Technical Field

The invention relates to the field of underwater connectors, in particular to an oil-filled sealing connector.

Background

The underwater connector is a necessary node for connecting underwater equipment and a necessary channel for realizing signal transmission, and the requirement of water resistance and moisture resistance is a basic condition required by the underwater connector. The economic significance of the sealing is far more than the price of the sealing. The economic loss due to the failure of the seal, which results in the equipment being shut down, is extremely costly. With the high importance of the country on the ocean development, ocean equipment is continuously increased, and the economic loss caused by the sealing failure of the equipment gradually increases every year, so that the underwater sealing problem is not solved slowly.

Most of the sealing forms of the connectors widely used in the market at present are radial sealing, and the radial sealing is most widely used by adopting an O-shaped sealing ring sealing method. The sealing form has the advantages of simple structure, compact size and convenient installation, and occupies a great share in the market. The O-shaped sealing ring is mainly used for static sealing and sealing of low-speed rotary motion. The O-shaped sealing ring is used for the connector, so that the use reliability in air is high. However, in the use process of the ocean severe environment, various random vibrations caused by the outside exist, such as non-periodic forced vibrations caused by high-speed cruising seawater impact; the method also comprises deterministic periodic vibration of the equipment and the structure, such as vortex-induced vibration with poor cable guide effect, self-excited vibration of the equipment under unbalanced acting force (such as unbalanced rotation of an underwater equipment mechanism), involved vibration of a carrying platform (such as periodic vibration of high-power transmitting sonar) and the like. External excitations of various frequencies and amplitudes together form an extremely complex vibration environment. The sealing form of the connector itself cannot therefore be regarded simply as a static sealing form, but rather as a quasi-static sealing form.

The structure machining precision and the installation precision are strictly checked under extremely complex vibration working conditions. Therefore, the underwater vibration environment with high pressure and humidity cannot be entered by sea water for a short time, but the long-term work cannot avoid the moisture infiltration. And a small amount of moisture is often a catastrophic consequence to high voltage, heavy load, high power equipment with high insulation requirements.
