Canted coil spring vs compression spring comparison covering structure, load behavior, fatigue life, EMI shielding performance, and applications to help engineers select the right spring solution.
When selecting a spring for precision mechanical or electrical applications, engineers frequently compare canted coil spring vs compression spring designs. Although both spring types serve to store mechanical energy and provide force, the canted coil spring offers fundamentally different performance characteristics compared to a traditional compression spring.
A コイルスプリング is specifically engineered to deliver consistent force, long fatigue life, and excellent electrical conductivity. In contrast, compression springs are widely used for general mechanical purposes but are limited in high-cycle and high-reliability environments. Understanding the difference between a コイルスプリング and a compression spring is essential for achieving optimal system performance.
A コイルスプリング is a precision spring made from a continuous wire formed into coils that are intentionally angled relative to the spring axis. This angled geometry allows each coil of the コイルスプリング to act independently during compression.
The unique structure of a コイルスプリング provides several mechanical advantages:
Because of this design, a コイルスプリング can maintain a near-constant force over a wide working deflection range.
A properly designed コイルスプリング offers:
These features make the コイルスプリング ideal for precision and high-reliability applications.
A compression spring is a conventional mechanical spring designed to resist axial compression. Unlike a コイルスプリング, a compression spring relies on parallel coils that stack against each other under load.
While a コイルスプリング distributes stress evenly across angled coils, a compression spring experiences increasing stress as coils come into contact. This structural difference explains why a コイルスプリング performs better in high-cycle applications.
| 特徴 | 傾斜コイルスプリング | Compression Spring |
|---|---|---|
| コイル形状 | Angled | Parallel |
| Stress Distribution | Even | Concentrated |
| Coil Interaction | Independent | Coil stacking |
| Friction | Low | High |
The structural advantages of a コイルスプリング directly result in superior mechanical and electrical performance.
One of the most important benefits of a コイルスプリング is its ability to maintain consistent force throughout compression. This makes the コイルスプリング ideal for applications requiring stable contact pressure.
Compression springs exhibit increasing force as deflection increases. In contrast, a コイルスプリング avoids excessive load buildup, protecting mating components and extending system life.
Because each coil in a コイルスプリング deflects independently, fatigue stress is significantly reduced. A コイルスプリング can withstand millions of cycles without significant performance degradation.
Compression springs experience coil friction and permanent deformation under repeated loads. In applications where long life is critical, a コイルスプリング is a far more reliable solution.
A コイルスプリング provides continuous conductive contact and uniform pressure, which is essential for effective EMI shielding. For this reason, the コイルスプリング is widely used in RF enclosures, connectors, and electronic housings.
Compression springs lack consistent electrical contact and are not designed for EMI shielding. In contrast, a コイルスプリング maintains electrical continuity even under vibration.
A コイルスプリング can be installed in various groove designs, including rectangular, dovetail, and circular grooves. This flexibility allows the コイルスプリング to accommodate misalignment and surface irregularities better than compression springs.
Common applications for a コイルスプリング を含む：
In each case, the コイルスプリング outperforms traditional compression springs in reliability and service life.
Although a コイルスプリング has a higher initial cost, its long service life and reduced maintenance make it a cost-effective solution over time. For high-reliability systems, a コイルスプリング offers superior total cost of ownership.
