The EMI Shielding canted coil spring Contact is a precision elastic contact component designed to establish continuous, low-impedance electrical grounding paths for electromagnetic interference control. By utilizing an angled coil structure, this type of canted coil spring maintains stable surface contact while accommodating mechanical tolerances, thermal expansion, and enclosure movement.
Unlike conventional grounding springs or finger contacts, the canted coil spring structure provides uniform radial force and multiple conductive contact points, ensuring reliable EMI performance over extended operating cycles. At YFS Technology (SZ) Co., Ltd, these spring contacts are engineered as part of comprehensive connector and grounding solutions, supporting system-level EMC compliance rather than isolated component performance.
This solution is especially suitable for electronic assemblies where shielding continuity, mechanical flexibility, and long-term contact reliability are required simultaneously.
The angled coil geometry ensures consistent surface contact along the shielding interface, reducing impedance fluctuations.
Provides controlled and repeatable contact pressure without excessive compression, protecting mating surfaces from damage.
Manufactured using conductive alloys with optimized plating to enhance grounding efficiency.
Accommodates enclosure deformation, vibration, and thermal movement without loss of shielding performance.
Supports EMI grounding in confined spaces where traditional shielding components are difficult to install.
Maintains consistent electrical continuity across shielding interfaces, helping reduce electromagnetic leakage and noise.
Resists relaxation and fatigue, ensuring grounding effectiveness over long service life.
Replaces complex grounding structures with a single integrated spring contact solution.
Supports overall EMI control strategy rather than isolated point grounding.
Spring diameter, coil angle, and surface finish can be tailored to meet specific shielding requirements.
Used between metal housings, covers, and frames to ensure continuous shielding paths.
Applied in base stations, routers, and RF modules requiring stable EMI grounding.
Supports electromagnetic compatibility in sensitive diagnostic and monitoring equipment.
Maintains shielding integrity in environments exposed to electrical noise.
Used in systems where EMI control and mechanical reliability are both critical.
