Circular connector and rectangular connector locking method analysis

Circular connectors and rectangular connectors using the appropriate locking method can increase the reliability of the product, in the design of manufacturers and customers to choose, according to the current product where the environment to choose the appropriate connector locking method. Rectangular connectors commonly used locking method 1, threaded connection: in order to prevent the connector to get plug and socket in the vibration and shock conditions of loosening, usually using fuses, positioning screws or ratchet structure. Characterized by a reliable connection, easy to use, commonly used in product size is relatively large use of the environment. 2, bayonet connection: rectangular connector socket on the outer circumference of the three pins 120 ° apart, with which the matching plug connection cap has a three-bend slot. Characterized by a rapid, reliable and easy to use connection, commonly used in the connection speed and product volume requirements of the environment. 3, push-pull connection: rectangular connector plug is designed as a set of locking tabs, when the plug is connected to the socket, the plug locking tabs inserted into the socket groove, locking the plug. At this time, pulling the plug or the end of the cable will not disconnect the circuit. Characterized by small size and high density. Circular connectors commonly used locking method 1, inline plug-in: relying on the plug socket guiding mechanism to achieve the connection of the device, commonly used between the printed circuit board and chassis cabinet connection. 2, screw locking method: through the plug socket guiding mechanism of the guide pin guide sleeve, to achieve the connector guidance and locking. Commonly used in the connection between the printed board and cable.
