Considerations For Insertion And Extraction Force When Plugs And Sockets Are Connected In Heavy-duty Connector Design

The insertion and extraction force of 4 pin heavy duty connector originates from the friction and normal force of the contact terminals. During the connection process, it manifests as a mechanical change that first resists the opening of the internal spring before entering a stable contact phase. When designing the structure of 6 pin heavy duty connector, engineers consider the influence of terminal materials, geometry, and contact surface treatment on the insertion and extraction force. Excessive insertion and extraction force may lead to assembly difficulties for connector heavy duty and increase the physical burden on operators, while also accelerating component wear under frequent use.
