iConn Engineering, LLC was established in 2011 in California, USA, and has been serving worldwide customers since. iConn is ISO 9001-2015 certified. Our specialty is to design each iConnFlex™ canted coil spring meticulously with finite element modeling techniques and manufacture precisely with CNC machines in our Taipei, Taiwan facility. 

Unlike conventional helical springs with circular cross-sections, canted coil springs all have oval cross-sections with different heights and widths (Figure 1). Varying the wire diameter (WD), width, height, or coil spacing changes the spring force. By design, we can target a specific canted coil spring for a holding/latching, or electrically conducting/EMI shielding application. A spring ring can be installed in a fitted groove to transmit electricity, energize plastic seals, control connecting force, provide bearing, or limit RF interference. So can a straight length of spring. An axial spring can control the binding force between two surfaces.

Compressing the coil height of a canted coil spring generates a force curve with a flat region (Figure 2). This force plateau is used to compensate for surface unevenness and dimensional variations in heat/cold, stabilize contact resistance in electrical plugs, and control engaging&disengaging force in the mechanical connectors. Canted coil springs are widely used in automotive, aeronautical and aerospace, green energy generation & storage, 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 reduce materials and space, limit assembly time and system cost, and provide reliable connections as the enablers of mechanical and electrical connectors.
