Description

Technical Field

[0001] The utility model relates to the technical field of underwater electrical connection, in particular to a watertight through-wall connector. Background Art

[0002] In various electronic systems, electrical connectors are used for electrical connection and signal transmission between devices, components, and systems. They are essential basic components for forming a complete system. At present, the domestic underwater small cable connectors and underwater wet plug-and-play technology are in the initial stage of research and development, and the key technologies still need to be broken through. With the development of offshore engineering equipment, unmanned systems, and underwater equipment, serialized underwater wet electrical general connection plugs will surely have a broad market prospect. Underwater wet electrical general connection plugs and small underwater connectors are mainly used in offshore oil and gas development, undersea resource exploration, marine environmental monitoring, and surface and underwater military platforms. In the upsurge of national marine economic development, the demand for connectors with the ability to work in underwater environments has increased significantly. Under certain water depth conditions, a watertight electrical connector not only requires a waterproof sealing function but also requires the system to work properly under certain water pressure conditions. This poses high requirements for both the connection stability and sealing stability of the connector. In addition, regarding how the sealing strip can meet high pressure in a high-pressure environment and at the same time facilitate the plugging and unplugging of the connector, therefore, a watertight through-wall connector is needed. Summary of the Utility Model

[0004] To achieve the above purpose and other related purposes, the present utility model provides the following technical solutions:

[0005] A watertight through-wall connector, comprising:

[0006] A through-wall socket, in which a pin connection plate and a pin mounting plate are sequentially arranged. The outer contour of the pin connection plate is arranged in a stepped shape, and a connection plate sealing ring is arranged between the high and low surfaces of the outer contour of the connection plate and the inner wall of the through-wall socket.

[0007] An inner plug, which is embedded in the front end of the through-wall socket. And a cover body is provided on the inner plug and is threadedly connected to the rear end of the through-wall socket. A pin mounting seat is provided at the front end of the inner plug. When the inner plug is embedded in the front end of the through-wall socket, the pins on the pin connection plate are embedded in the pin holes in the pin mounting seat.

[0008] To implement the above technical solution, the outer contour of the core pin connection plate is arranged in a stepped shape, and connection plate sealing rings are respectively arranged between the high and low surfaces of the outer contour of the connection plate and the inner wall of the wall-through socket, so that the outer contour of the external connection plate on the high and low surfaces is independently sealed with the inner wall of the wall-through socket, thereby ensuring the sealing reliability. The stepped outer contour of the core pin connection plate can cooperate with the inner wall contour of the wall-through socket to position the installation position of the core pin connection plate, thereby ensuring the installation accuracy of the core pin connection plate in the wall-through socket.

[0009] Inserting the inner plug into the front end of the wall-through socket can ensure the convenience during the connection process of the inner plug. The wall-through socket is used to position the displacement of the inserted inner plug to ensure the connection stability and connection accuracy of the inner plug.

[0010] In an embodiment of the present invention, the outer contour of the core pin mounting seat is arranged in a stepped shape, and mounting seat sealing rings are respectively arranged between the high and low surfaces of the outer contour of the core pin mounting seat and the cover body.

[0011] To implement the above technical solution, the outer contour of the core pin mounting seat is arranged in a stepped shape, and the high and low surfaces of the outer contour of the core pin mounting seat are independently sealed by the mounting seat sealing rings, which can improve the sealing stability between the core pin mounting seat and the cover body. The front end of the cover body abuts against the inner wall of the wall-through socket, and the front end of the cover body extends all the way to the gap between the core pin connection plate and the core pin mounting seat to ensure the connection stability between the core pin connection plate and the core pin mounting seat. The stepped outer contour of the core pin mounting seat is used to cooperate with the inner step corresponding to the stepped contour in the cover body to limit the insertion position of the core pin connection plate and assist the connection convenience and stability between the core pin connection plate and the core pin mounting seat.

[0012] In an embodiment of the present invention, a cap is provided on the cover body, and the front end of the cap is threadedly connected to the rear end of the wall-through socket.

[0013] To implement the above technical solution, the setting of the cap can facilitate the installation of the cover body on the wall-through socket and ensure the connection stability and reliability with the wall-through socket.

[0014] In an embodiment of the present invention, a cover body sealing groove is provided on the cover body below the threaded connection surface between the cap and the rear end of the wall-through socket, and a cap sealing ring is provided in the cover body sealing groove.

[0018] In an embodiment of the present invention, a plug limiting screw ring that is threadedly connected to the inner wall of the cover body is provided at the rear end of the inner plug, and the plug limiting screw ring presses against the inner plug.

[0019] To implement the above technical solution, by setting the plug limiting screw ring to press against the inner plug, the core pin mounting seat of the inner plug can be stably inserted on the core pin connecting plate, and the inner plug will not generate axial displacement during use, ensuring the stability of the inner plug during use.

[0020] In an embodiment of the present invention, a socket flange is provided on the outer wall of the through-wall socket. An outer wall sealing ring is provided on the outer wall of the through-wall socket on the side away from the inner plug, and the core pin connecting plate is located below the socket flange.

The outer contour of the pin connection plate is arranged in a stepped shape, which can cooperate with the inner wall contour of the wall-through socket to position the installation position of the pin connection plate, thereby ensuring the installation accuracy of the pin connection plate in the wall-through socket.

[0025] Inserting the inner plug into the front end of the wall-through socket can ensure the convenience during the connection of the inner plug. Using the wall-through socket to position the displacement of the inserted inner plug can ensure the connection stability and connection accuracy of the inner plug. After the inner plug is inserted into the front end of the wall-through socket, the pins on the pin connection plate are inserted into the pin holes in the pin mounting seat, and there is an axial gap between the pin connection plate and the pin mounting seat, ensuring the stability and reliability of the connection.
