Push pull self-locking connector is a reliable connector, which works by locking the plug and socket together through an internal locking mechanism. Circular push-pull self-locking connectors usually consist of a plug and a socket. The socket is usually installed on the device, while the plug is installed on the connecting wire. When connecting, insert the plug into the socket and push the plug forward until the internal locking mechanism between the plug and socket locks them together. This connection method does not require any external attachments such as threads or buckles, making it very convenient and fast, and also safer and more reliable.
