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.

When disconnecting, simply press the button on the plug and pull the plug backwards. This button will release the locking mechanism between the plug and socket, allowing them to separate. Due to their non threaded connection, waterproof push-pull self-locking connectors are highly suitable for applications that require frequent disassembly and connection, such as LED lighting, automotive electronics, and medical equipment.

① Connection method



The connection method of push-pull self-locking connectors is very simple, usually just connect the plugs and sockets at both ends to each other. When the plug is inserted into the socket, the push-pull self-locking connector will make a "click" sound, indicating that the connection is firm and no other fixing parts are needed for fixation.















② Installation method



The installation method of push-pull self-locking connectors depends on the type and installation method of the connected equipment. Usually, the plug and socket need to be installed separately on the device to be connected, and then the plug is inserted into the socket for connection. When installing plugs and sockets, it is necessary to pay attention to their correct installation direction and position to ensure that the connectors can be connected correctly.















③ Maintenance method



The maintenance of push-pull self-locking connectors is relatively simple, usually only requiring keeping the connectors clean and dry. When cleaning the connector, you can use a clean cotton cloth or cotton swab to gently wipe the plug and socket parts of the connector. Avoid using cleaning methods such as water or chemical cleaners that may damage the connector.




#unit-Z4CroujQU1YXet1 [ce-data-type="text"]{text-align:left;}#unit-Z4CroujQU1YXet1{padding-top:1vw;}

In addition, attention should be paid to some details when connecting and disassembling push-pull self-locking connectors, such as avoiding excessive force to pull out the plug, avoiding frequent connections and disassembly to reduce wear and tear on the plug and socket, etc. These can effectively extend the service life of the connector.

① Easy to plug in



The push-pull self-locking connector has a more convenient way of inserting and unplugging, simply pushing the plug to complete the insertion, while the threaded connector requires rotating the plug for insertion. Especially in some narrow spaces, push-pull self-locking connectors are easier to plug and unplug.















② Self locking performance



Push pull self-locking connectors have good self-locking performance, and the plug can automatically lock after insertion, making it difficult to fall off. Threaded connectors, on the other hand, require manual tightening. Insufficient tightening can lead to loosening, while excessive tightening may result in connector damage.















③ Applicable occasions



Push pull self-locking connectors are more suitable for occasions that require frequent disassembly and installation, such as automotive electronics, aerospace and other fields; Precision threaded connectors are more suitable for applications that require long-term fixation, such as machinery and equipment.















④ Size



The push-pull self-locking connector has a relatively small volume and occupies less space during installation; And the threaded connector is larger, requiring a larger space to be reserved for installation.















⑤ Price



Industrial push-pull self-locking connectors are relatively expensive, while threaded connectors are more cost-effective.
