Description

plug connector

technical field

The utility model relates to a plug connector, in particular to a plug connector with an unlocking mechanism.

Background technique

In order to ensure that the plug connector and the socket connector are firmly kept together, the plug connector is usually provided with a locking device. When the plug connector is inserted into the socket connector, the locking device is locked on the socket connector, and the plug connector is pulled out. Before going out, the locking device needs to be unlocked by the unlocking mechanism, so the structure and movement mode of the unlocking mechanism are particularly important, which will affect the operator's experience.

For the prior art related to this case, you can refer to a plug connector disclosed in Chinese Patent Announcement No. 203734061U. The plug connector includes a plug body and an unlocking mechanism on the plug body. Blocks, springs and drawstrings and other parts. The locking block includes a pivoting part, a locking part protruding forward from the pivoting part, and an extension part protruding backward from the pivoting part. The pivoting part is fixed on the plug body through a rotating shaft. In the front-to-back direction, the lock part is closer to the center of gravity of the lock block than the extension part. When the lock block is not subjected to external force, the lock part has a downward movement force, and the front part of the lock part has an upwardly protruding lock. The hook is used to lock up to the concave part of the socket connector. The spring presses forward on the slider, and the front end of the slider presses downward on the extension of the lock block. The slider has a horizontal surface that contacts the slider. The slider is connected with the drawstring, and the drawstring extends backward out of the plug ontology. When unlocking, the pull belt pulls the slider to overcome the elastic force of the spring and move backwards, the slider breaks away from the horizontal plane of the lock block, and the lock part automatically moves downwards by gravity, prompting the lock hook to exit the recess of the socket connector downwards, unlocking the socket connection The lock of the connector, the plug connector can be easily pulled out of the socket connector. However, since the locking part moves downwards by its own gravity, if the frictional force between the locking hook and the inner wall of the concave part of the socket connector is greater than the gravity, it is difficult for the locking part to move downwards, so that the unlocking is not smooth, and even Failed, affecting the user experience of the operator.

Therefore, it is necessary to design a new plug connector to solve the above technical problems.
