China Battery Springs Suppliers - Reliable Factory for Conical Battery Contacts in Various Configurations
Description
🔋
What makes these battery spring contacts reliable?
Our battery spring contacts have been designed to adjust to varying battery lengths and provide low contact resistance and dependable connections.
⚙️
Which battery sizes do these springs work with?
Each of the four battery contact configurations is designed to work with the four most popular battery sizes: AA, AAA, C, and D.
Standard Battery Spring Material Options
The springs are offered in a choice of two materials: nickel coated music wire or silver coated beryllium copper. If our standard product designs do not meet your requirements, we can provide custom designs for battery springs, four slide part contacts or stampings.
✅
What other benefits does nickel coating provide?
Nickel will tend to wipe and aid in breaking down the oxide that can form on the battery metal contact surface. In addition, a nickel coating will provide general corrosion resistance and is an excellent conductor of electricity.
💎
Silver Coated Beryllium Copper
Beryllium Copper is among the hardest, strongest and most wear-resistant of the copper alloys. The silver coating further enhances electrical and thermal conductivity.
Application
How does silver coated beryllium copper compare to other materials?
❑
The electric conductivity is 65–70% that of copper; the strength and fatigue resistance are comparable to higher beryllium alloys. The light silver plating allows for easy soldering. Beryllium copper is corrosion resistant in various environments and is both non-magnetic and non-sparking.
❑
Battery Spring Mounting Configuration Options
❑
Battery Springs are available in a choice of four conical spring configurations:
❑
Interior Mount – Designed for installation inside battery compartments
❑
Exterior Mount – Positioned on the outside of battery housing
❑
Adjustable Mount – Allows for flexibility in positioning and battery size accommodation
❑
Double Mount – Provides dual contact points for enhanced connection reliability
Programing
Which battery spring mounting configuration should I choose for my application?
The choice depends on your specific battery compartment design, space constraints, and connection requirements. Interior mounts work well for compact designs, while adjustable mounts offer the most versatility for varying battery sizes.
