The Shielding-Grade canted coil spring Contact is a specialized elastic contact element designed to provide continuous electrical grounding and electromagnetic shielding across mating surfaces. Its angled coil geometry allows the spring to maintain stable conductive contact while compensating for surface irregularities, mechanical tolerances, and structural movement.
In modern electronic systems, electromagnetic interference has become a critical design challenge. Inconsistent grounding or shielding gaps can result in signal distortion, data loss, or system instability. To address these issues, YFS Technology (SZ) Co., Ltd develops canted coil spring contacts as part of integrated EMI control and connector grounding solutions, rather than as isolated components.
By combining elastic compliance with multi-point electrical contact, shielding-grade canted coil springs help ensure reliable grounding paths, even under vibration, thermal cycling, or repeated assembly operations.
The angled coil structure creates multiple simultaneous contact points, improving grounding continuity and reducing contact impedance.
The spring adapts to uneven mating surfaces, coatings, or tolerance variations without compromising electrical contact.
Maintains consistent pressure across the contact interface, preventing intermittent grounding caused by mechanical movement.
Optimized coil geometry and material selection support efficient current flow for grounding and shielding functions.
Available in copper alloy, beryllium copper, or stainless steel with conductive surface treatments.
Provides continuous grounding paths that help suppress electromagnetic leakage and interference.
Maintains electrical continuity during vibration, thermal expansion, or repeated opening and closing of enclosures.
Elastic contact design minimizes the need for rigid metal shields or complex fastening structures.
Resists fatigue and maintains electrical performance over extended operational life.
Can be incorporated into housings, frames, connector interfaces, and modular assemblies with minimal design changes.
Used in base stations, network switches, routers, and RF enclosures requiring stable grounding and EMI control.
Applied in chassis grounding, module interfaces, and enclosure shielding to maintain signal integrity.
Supports electromagnetic compliance in diagnostic and monitoring equipment.
Used in control cabinets, automation systems, and power electronics requiring reliable EMC performance.
Applied in precision electronic housings where space-efficient shielding solutions are required.
