In addition, various electronic devices (such as: smart phones, tablet computers, desktop computers, notebook computers, digital cameras, etc.) usually have to be configured on the body of each electronic device in order to receive electronic signals and power from the outside world. A signal connector, generally speaking, a signal connector (Connector) refers to all the connecting components and their accessories used in electronic signals and power supplies. It is the bridge of all signals, and its quality will affect the reliability of current and signal transmission. It affects and is closely related to the operation of the electronic device. Through the function of the signal connector, multiple electronic devices can be connected to form a complete system to transmit electronic signals or power to each other. Therefore, it can be seen that the signal connector is actually the electronic device. Elements that are indispensable to achieve a predetermined function.

Generally speaking, in order to ensure the connection stability between the signal connectors, the connector group of the wire-to-board (WTB) structure (ie, the plug connector 11 and the receptacle connector 12 ) is usually provided with a locking mechanism, such as the first As shown in FIG. 1, the plug connector 11 is provided with a hook 111, and the socket connector 12 is provided with an inserting block 121. In this way, when the plug connector 11 is inserted into the socket connector 12, the The hook 111 is then fixed on the inserting block 121 , so that the plug connector 11 and the socket connector 12 can be stably combined. The inventor found that most of the locking mechanisms (eg, the hook 111 and the inserting block 121 ) of the existing connector set are exposed without any additional protection mechanism. Therefore, when the connector set is affected by external force, its The locking mechanisms are easily separated from each other, thereby causing the plug connector 11 and the socket connector 12 to be easily separated from each other; in addition, most of the aforementioned locking mechanisms are made of a plastic base, so their structural strength is bound to be poor. After the collision, it is easy to break, and the expected locking effect cannot be achieved.

From the above, it can be seen that the locking mechanism of the current connector group is still partially missing. Therefore, how to effectively improve the aforementioned problems without adopting an overly complicated protection mechanism and without excessively increasing the volume of each connector is the basic problem. The utility model is a major topic discussed here.
