Precision Copper Conical Compression Springs With Custom Bent Wire Leads

Precision Copper Conical Compression Spring with Custom Bent Wire Leads – Conductive & Elastic Component for Electronic and Mechanical Applications

This precision-engineered copper conical compression spring is a high-performance metal component designed for use in a wide range of electronic and mechanical applications. Manufactured from high-purity copper wire, the product features both excellent electrical conductivity and mechanical resilience, making it ideal for environments requiring reliable elastic force and efficient signal or power transmission.

The spring consists of two main structural parts:
• Conical Helical Spring Body:
The core structure is a tightly wound helical spring with a conical shape—its coil diameter gradually decreases from bottom to top. The coils are uniformly spaced and display a clean, symmetrical spiral form. This conical design allows for variable spring rates and space-efficient compression behavior, ideal for precision assemblies.
• Custom-Formed Wire Leads:
Extending from one end of the spring is a meticulously shaped metal lead. It features a wave-like bending pattern with a functional curvature, ending in a small hook structure. This lead design enhances mechanical stability and facilitates secure integration into circuit boards or mechanical fixtures.

Its compact, efficient design and dual-functionality (elastic + conductive) make it suitable for:
• Electrical contacts and terminals
• Switch mechanisms
• Vibration dampening systems
• Precision connectors
• Custom electromechanical assemblies
