iConn Engineering, LLC was established in 2011 in sunny Southern California, USA, and has been serving worldwide customers since. We manufacture all canted coil springs in our Taipei, Taiwan facility. iConn is ISO9001-2015 certified. Our specialty is to design each canted coil spring meticulously with finite element modeling techniques and manufacture them precisely with CNC machines.
What is a canted coil spring?
Unlike conventional helical springs with circular cross-sections, a canted coil spring has an oval cross-section with a different height and width (Figure 1). Varying the wire diameter (WD), width, and height of a canted coil spring changes the spring force. By design, we can target a specific canted coil spring for a holding/latching, or electric transmission/EMI application. A straight length of spring can be utilized for grounding, conducting, or EMI shielding. A spring ring can be installed in a fitted groove to run electricity, energize plastic seals, control connecting force, provide bearing, or limit RF interference.
Compressing the coil height of a canted coil spring generates a force curve with a flat region. This force plateau is used to compensate for surface unevenness and tolerance variations in seals, maintain contact resistance in electrical contacts, and control disengaging force in plug-in connectors. Canted coil springs are widely used in automotive, aeronautical and aerospace, green energy, healthcare, Laser apparatus, lighting, military, power transmission & distribution, oil & gas, and transportation power industries.
If you are still using conventional ways for round part holding or quick disconnecting applications, there is a good chance you can benefit from the convenience and cost-saving features of canted coil springs. They save materials and space, reduce assembly time and system cost, and provide reliable connections as the enablers of mechanical and electrical connectors.
