[0002] With the development of marine survey technology, the depth of underwater operations continues to increase, and connectors used in underwater equipment face huge deep-sea pressure. In order to solve the problem of limited pressure bearing capacity of watertight connectors at great depths, it is usually designed to balance the pressure of connectors by filling oil or glue inside the connector shell, so as to improve the use depth and environmental adaptability of watertight connectors.

[0003] In practical applications, the process of filling connectors with oil or glue is mostly done on-site, requiring the filling equipment to be flexible and lightweight. Existing connector filling equipment is mostly fixed special filling equipment, which is large in size, heavy in weight, inconvenient to carry, and not conducive to on-site operations.

[0004] For example, a Chinese invention patent with authorization announcement number CN110474219 B discloses an oil filling tool for an oil-sealed electric connector, which includes an oil filling cylinder, a guide rod and a pressurizing piston. One end of the oil filling cylinder is provided with an electric connector connection structure for connecting to the shell of the oil-sealed electric connector, the guide rod is provided with a plug connection structure for connecting to the plug of the oil-sealed electric connector, the pressurizing piston uses the oil filling cylinder as a cylinder body, and the middle part of the pressurizing piston is provided with a through hole that cooperates with the guide rod in a seal.

The oil filling cylinder is fixed to the connector housing by screws, which makes the connection operation complicated and the disassembly and assembly inconvenient; 2. When filling oil, the plug is located inside the housing. The guide rod needs to be connected to the plug through a thread, and then the pressurizing piston is installed and pushed to fill oil. Finally, the plug is pulled to seal the oil filling hole. There are many steps in the use process, and the components need to be disassembled repeatedly, which is inconvenient to operate; 3. The oil in the oil filling cylinder automatically flows into the housing of the oil-sealed electrical connector under the action of gravity. Therefore, it is only applicable to connectors with the oil filling hole set at the top of the connector, and the scope of application is small; 4. After the oil filling is completed, the oil is compressed by the pressurized piston, and the pressure cannot be accurately controlled, resulting in poor filling effect.
