Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a connector with elastic locking and stability. Background Art

[0002] Current connectors are often used in our daily life, such as in the automotive industry, air conditioning industry, electric vehicle industry, drone industry, etc. Current connectors play a very important role. Current connectors basically work together between connectors and connector sockets.

[0003] Taking the electrical connector used for drones as an example, it generally includes a male connector and a female connector, which are plugged in by plugging the male connector and the female connector together to achieve plug connection, and the electrical connection is achieved by the contact between the terminals. The male connector and the female connector are generally locked and connected to each other through a threaded structure, and the connection stability is poor, and it is easy to loosen or fall off; some male connectors and female connectors are locked by a buckle locking structure. When plugging in, it is only necessary to plug the buckle of the male connector into the buckle groove of the female connector, and keep the lower end of the buckle of the buckle against the groove of the female connector, so as to prevent the male connector from being detached from the female connector. This locking method that only relies on the single buckle has insufficient reliability of unilateral force on the male connector in actual use, and the male connector is easy to shake in the female connector, resulting in insufficient holding force of the locking position between the two, which causes looseness or falling off and affects use.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
