Circular connector three commonly used locking methods

As a key connection component in industrial and commercial fields, circular connectors are locked in a way that directly affects the stability of the connection, the ease of operation and the reliability of the application. Different locking methods are suitable for different use scenarios, and understanding their characteristics and applications helps to choose the right connector. This article will introduce the three common locking methods of circular connectors: thread locking, snap locking and push-pull locking.

1. Screw lock
Thread locking is a traditional and widely used locking method that securely connects plugs and receptacles together through thread rotation.

Features:

  • High fastness: thread locking can withstand greater tension and vibration, suitable for harsh environments and occasions requiring high mechanical stability.
  • Good sealing: The screw lock is usually equipped with a seal, can achieve IP67 or higher protection class, suitable for outdoor equipment and industrial environment.
  • Installation time consuming: Compared to other locking methods, thread locking requires rotating operation and may be slightly time-consuming.

Application scenario:
Industrial automation equipment, outdoor communication equipment, aerospace and military fields

 

2. Lock the buckle
Fastener locking with prefabricated slots and fastener mechanisms for plugs and sockets for fast connection, easy operation and high efficiency.

Features:

  • Fast and convenient: The latch can be locked by simply inserting and gently pressing, which is suitable for frequent insertion and removal.
  • Lower cost: Compared with thread and push lock, snap lock has lower production cost, so it is widely used in middle and low-end equipment.
  • General fastness: Because there is no rotating or sliding mechanism, the vibration resistance and mechanical stability of the buckle lock are slightly weak, suitable for a more stable environment.

Application scenarios:

Consumer electronic devices, low vibration indoor environments, laboratory instruments

3. Push and pull to lock
Push-pull locking is an efficient locking method that has developed rapidly in recent years, which can be connected and unlocked by simple pushing and pulling actions.

Features:

  • Fast operation: The push-pull connector design simplifies the insertion and removal process, greatly improving the efficiency of installation and replacement.
  • Strong fastness: Although easy to operate, the push-pull lock still has strong tensile and vibration resistance.
  • Advanced applications: Due to its complex design, the cost of pushing and pulling the locking connector is high, and it is mainly used in equipment with high performance requirements.

Application scenario:
Medical equipment, high-end industrial automation systems, precision instruments and testing equipment
