Charging cable products require smooth pull-out, reliable return, and compact storage. Cable springs help control the cable path and provide the return force needed for repeated daily use.
Common applications
- Power bank cable modules
- Retractable USB and charging cables
- Consumer electronics with cable storage
- Portable devices with compact cable routing
Key design inputs
- Cable length, cable diameter, and cable stiffness
- Required pull-out force and return force
- Housing space and outlet direction
- Expected cycle life and user operation frequency
Selection notes
A cable spring should be designed together with the cable path. The spring force, cable friction, and reel structure must work together, otherwise the cable may not retract smoothly.
