Description

Technical Field

[0001] The utility model relates to the technical field of watertight connectors, in particular to a plug-in watertight connector with double sealing rings. Background Art

[0002] Watertight connectors are an indispensable and important unit component of marine robots and related application fields. They undertake important missions and play an important role. Watertight connectors are used to connect two sets of cables. During use, the firmness and sealing effect of the connection must be ensured.

[0003] The existing watertight connector generally includes a socket and a plug, so that two sets of cables are installed with the plug and the socket respectively, and the two sets of cables can be connected by plugging the plug and the socket;

[0004] Since the existing watertight connectors often use a plug-in connection method to install the two sets of cables during the connection process, it is easy for the plug to be detached from the inside of the socket under external tension, and the firmness of the connection between the two sets of cables cannot be guaranteed. At the same time, in order to ensure the sealing of the connector, a sealing ring is often installed inside the connector, which can play a certain sealing role. However, the sealing ring is often located inside the connector, and the connection of the connector has not been sealed, thereby reducing the sealing effect of the watertight connector. In view of the shortcomings of the existing technology, we propose a plug-in watertight connector with double sealing rings to solve the above problems. Utility Model Content
