The Conductive Shielding canted coil spring is a precision spring contact designed to provide continuous electrical grounding and electromagnetic shielding between conductive surfaces. Unlike traditional gasket materials or flat grounding springs, this canted coil spring delivers consistent radial force and stable multi-point contact, ensuring low-impedance electrical continuity over long service life.
Developed by YFS Technology (SZ) Co., Ltd, this product is positioned as a connectivity and grounding solution rather than a simple spring component. Through optimized coil geometry and conductive material selection, the spring maintains reliable contact performance even in applications subject to vibration, thermal cycling, or repeated assembly.
This type of canted coil spring is widely adopted in modern electronic enclosures and shielding structures where EMI control and grounding integrity are essential to system stability.
The angled coil structure creates multiple contact points along the mating surface, forming a stable and continuous conductive path.
Precision-controlled contact pressure minimizes electrical resistance, supporting effective grounding and EMI attenuation.
Automatically adapts to surface irregularities and dimensional tolerances without loss of contact performance.
When installed circumferentially, the spring enables full-perimeter electrical continuity between mating components.
Manufactured using copper alloys, stainless steel, or specialty conductive materials with optional silver or nickel plating.
Maintains stable grounding paths that help reduce electromagnetic interference and signal leakage in sensitive electronic systems.
Unlike conductive foams or fabric gaskets, the spring does not suffer from compression set or material aging.
Consistent contact force prevents micro-disconnections caused by mechanical shock or vibration.
Supports slim enclosure designs without requiring additional shielding structures or complex assemblies.
Spring diameter, coil density, and wire thickness can be customized to match enclosure and shielding requirements.
Used in base stations, routers, switches, and RF enclosures to ensure grounding continuity and EMI suppression.
Applied in server housings, power distribution units, and shielding frames where electrical noise control is critical.
Supports EMI control in control cabinets, industrial PCs, and automation systems.
Used in shielded housings where signal integrity and electromagnetic compliance are required.
Ideal for compact systems requiring reliable shielding without sacrificing space efficiency.
Q1: How does this spring improve EMI shielding?
