A canted coil spring is a precision spring that features an elliptical (oval) cross section, and coils that are angled relative to its axis Cut and often welded into rings, these springs are used to create compliant, connecting, conducting, or shielding interfaces across a wide range of applications including medical devices, fuel pumps, battery sensors, and more Unlike traditional, helical springs that increase in force with compression, canted coil springs maintain a consistent load, which helps reduce wear and improve overall service life and reliability. This paper discusses joining the ends of canted coil springs without changing the wire geometry.
