Description

Connector with locking and unlocking structure

The present invention belongs to the technical field of connectors, in particular to a connector with a locking and unlocking structure.

Traditional connectors, such as LVDS connectors, are unlocked through the unlocking device located at the cable end, which requires a large space to operate, and because it is located at the cable end, it is impossible to clearly determine whether it has been unlocked or is still locked. If the cable is not unlocked, forcibly pulling out the cable will cause the locking structure to be broken. In view of this, a tie rod structure on both sides has also been developed to solve the above problems. Although the tie rod structure achieves the purpose of automatic locking and automatic pop-up unlocking, and can also easily identify the locked and unlocked states, when the connection If the device is used in small or even micro application fields, it will be difficult for users to operate the lever.
