Welding Power Socket Spiral Spring Contact Design

The spring element provides a dynamic, elastic connection that can accommodate movement and pulling forces while maintaining continuous contact. The spring's ability to deform and recover ensures the plug element remains securely connected even when subjected to external forces, eliminating the loosening problem of rigid bayonet locks.

The spring element changes the mechanical parameters of the connection by introducing elastic deformation capability. This allows the connection to maintain optimal contact pressure under varying conditions, including when pulling forces are applied to the hose package, thereby preventing increased contact resistance.

The spring element is divided into multiple segments or windings, each creating a contact point with the plug element. This segmentation transforms a single contact point into multiple parallel contact paths, increasing the total current transfer capability while maintaining a relatively simple overall structure.

The spring element transitions the contact from a single point contact to a multi-point contact along the axial dimension. The spring windings create multiple contact interfaces in the axial direction, effectively increasing current transfer capability without significantly increasing radial or lateral complexity.

The spring element's elastic properties allow it to adapt to slight misalignments during insertion. As the plug element is inserted, the spring can deform to accommodate positional variations while still maintaining adequate contact pressure, ensuring reliable current transfer even when perfect alignment is not achieved.

The spring element provides a cushioning effect that compensates for alignment variations before they can cause excessive contact resistance. The elastic deformation of the spring absorbs the misalignment errors, preventing them from translating into poor electrical contact and potential overheating.
