Circular connectors are widely used connection devices in the industrial field, often requiring stable connections in harsh environments such as vibration, humidity, and corrosion. In order to ensure the stability of its connection, it is necessary to choose the appropriate locking method according to the specific usage environment to improve the reliability of the product. The following are three commonly used locking methods for circular connectors:
1、 Thread locking
Thread locking utilizes the self-locking characteristics of threads to tightly connect the plug and socket. To prevent loosening under vibration or impact conditions, fuses, set screws, or ratchet structures are usually used for reinforcement. This method of connection is reliable and easy to use, but the speed of insertion and separation is relatively slow and requires a large operating space, making it more suitable for use in environments with sufficient operating space.
2、 Bayonet locking
The locking method of the bayonet is achieved by setting three 120 degree spaced locking pins on the outer circumference of the socket, which are matched with the slot structure on the other end to achieve quick tightening. This operation method is convenient, but the locking force mainly depends on the compression force generated by the waveform spring inside the connecting cap, so it cannot provide a rigid locking effect.
3、 Push pull locking
In situations where space is limited or rotation locking is inconvenient, push-pull locking becomes the preferred method for circular connectors. This method has a locking spring on one side of the plug. When the plug is inserted into the socket, the locking spring will be embedded in the groove of the socket, firmly locking the plug in the socket. At this point, whether pulling the tail of the plug or the cable, the plug and socket will not separate. And only when the plug cap shell is pulled, will the two separate. This method is easy to operate and has stable connections, making it very suitable for situations with limited space.
