[0002] Connectors, also known domestically as plugs, sockets, or connectors, generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals. Connectors are components frequently encountered by electronic engineers; their function is very simple: to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Connectors are indispensable components in electronic equipment; following the path of current flow, you will always find one or more connectors. Connector forms and structures are highly diverse. Depending on the application, frequency, power, and application environment, various types of connectors exist. With continuous technological advancements, underwater power transmission cables are increasingly deployed, requiring connectors to connect these cables.

[0003] Threaded connectors are commonly used when connecting cables. However, even when the cable connection is secured, existing threaded connectors can easily loosen or even fall off due to vibrations between the connector and the cable over time. Therefore, there is an urgent need for an anti-loosening threaded locking connector to overcome these defects. Summary of the Invention
