Product Introduction

The canted coil spring is a precision-engineered spring contact designed to deliver consistent force, reliable electrical conductivity, and extended service life in demanding connection environments. Unlike traditional compression or leaf springs, the canted coil spring features angled coils that provide uniform deflection and stable contact force across a wide range of tolerances.

At YFS Technology (SZ) Co., Ltd, canted coil springs are developed as part of an integrated connector solution rather than as standalone components. Through optimized coil geometry, material selection, and surface treatment, these springs are tailored to support both mechanical retention and electrical continuity in compact, high-performance systems.

Canted coil springs are widely used where repeated mating, vibration resistance, and long-term reliability are critical, making them ideal for modern electronic, industrial, and transportation applications.

Product Features

Angled Coil Structure

The unique canted coil design allows the spring to compress evenly, maintaining consistent contact force throughout its working range.

Stable Electrical Contact

When used as a conductive element, the spring provides multiple contact points, reducing contact resistance and improving signal stability.

Wide Tolerance Compensation

The spring adapts easily to dimensional variations, helping maintain reliable contact even with misalignment or manufacturing tolerances.

Long Cycle Life

Designed for high mating cycles without permanent deformation, supporting long-term operation.

Material and Plating Flexibility

Available in stainless steel, copper alloy, or specialty materials with optional gold, silver, or tin plating.

Product Advantages

Consistent Force Output

Unlike traditional springs that experience rapid force decay, canted coil springs deliver stable and predictable force over repeated compression cycles.

Dual Functionality

Capable of serving as both a mechanical spring and an electrical contact, reducing component count in connector designs.

Excellent Vibration Resistance

The multi-point contact structure helps prevent intermittent contact caused by shock or vibration.

Compact Design Integration

Suitable for space-constrained designs where conventional spring mechanisms are impractical.

Application-Specific Customization

Spring diameter, wire thickness, coil angle, and plating can be customized to match exact application requirements.

Product Applications

Electrical Connectors

Used as internal contact elements in spring-loaded connectors, test interfaces, and modular connection systems.

Automotive and New Energy Systems

Applied in EV battery modules, charging interfaces, and control units requiring stable conductive contact under vibration.

Industrial Equipment

Ideal for automation equipment, sensors, and industrial controllers exposed to frequent mechanical movement.

Medical Devices

Suitable for diagnostic and monitoring equipment requiring reliable electrical continuity and repeatable performance.

Aerospace and Defense

Used in mission-critical systems where durability, consistency, and performance stability are essential.
