Description
Product Overview
This precision-engineered coin cell spring is custom-designed for CR2032 coin cell cans, featuring strict dimensional specifications: outer diameter of 15.4 mm × height of (1.2±0.03) mm × thickness of 0.2 mm, with a lightweight profile of merely 0.1 ounces per unit. It exhibits ultra-high dimensional precision and robust elastic recovery performance, ensuring seamless integration into internal battery assemblies and sustained operational stability under cyclic pressure conditions.
Material & Craftsmanship Advantages
Dual-Performance Gold-Plated Coating
Fabricated from high-grade stainless steel with a uniform gold-plated finish, the spring offers two core functional advantages:
- Superior Corrosion Resistance: Forms a dense protective barrier against electrochemical oxidation and chemical degradation, rendering it suitable for long-term service in humid or corrosive operating environments.
- Stable Electrical Conductivity: Minimizes contact resistance between battery electrodes and external circuits, ensuring uninterrupted current transmission to meet the operational demands of high-reliability electronic devices.
Precision Machining & Surface Quality
The spring surface undergoes precision polishing to achieve a smooth, impurity-free finish, complying with the stringent cleanliness and tolerance requirements for precision battery internal assembly. This eliminates the risk of short circuits or component damage caused by surface defects.
Compatibility & Supporting System
Broad Model Compatibility
While optimized for CR2032 coin cell cans, we also provide a full suite of matching components for mainstream coin cell models including CR2016, CR2025, and CR2450, covering diverse application scenarios.
One-Stop Procurement Solution
We offer a comprehensive product portfolio, including multi-material coin cell cans (304 stainless steel/316 stainless steel/aluminum-coated), multi-specification stainless steel/pure aluminum gaskets, and wave springs. This enables customers to realize integrated procurement of all battery assembly components.
Core Functional Highlights
- Precise Elastic Contact: Delivers consistent and uniform preload to ensure tight contact between battery electrodes and circuits, preventing contact failure induced by vibration, thermal expansion, or contraction.
- Buffering & Pressure Mitigation: Absorbs mechanical stress generated during battery charge-discharge cycles, protecting internal components from structural damage and extending battery service life.
- Stable Current Conduction: The gold-plated surface maintains low contact resistance even after prolonged use, meeting the high-reliability requirements of mid-to-high-end electronic devices.
