Battery holders, clips, and contacts are electromechanical components designed to securely mount batteries in electronic devices while ensuring reliable electrical connectivity. These components play critical roles in power delivery systems, enabling safe and efficient operation across industries. Their importance has grown with the proliferation of portable electronics, IoT devices, and renewable energy systems.
| Type | Functional Features | Application Examples |
|---|---|---|
| AA/AAA Battery Holders | Plastic housing with spring-loaded contacts, polarity protection | Remote controls, flashlights |
| CR2032 Coin Cell Holders | Low-profile design, snap-in installation | Smartwatches, calculators |
| Spring Clips | High conductivity, vibration resistance | Medical devices, industrial sensors |
| PCB Mount Contacts | Surface-mount technology (SMT), high cycle life | Wearables, wireless earbuds |
Typical construction includes: - Insulating housing (ABS/PVC/nylon) - Conductive elements (phosphor bronze, beryllium copper) - Contact plating (gold, nickel, tin) - Mechanical retention features (snap tabs, screw terminals) - Polarization guides (molded keying features)
| Parameter | Importance |
|---|---|
| Rated Current (0.5-5A) | Determines maximum power capacity |
| Contact Resistance (5-50m ) | Affects energy efficiency and heat generation |
| Insulation Resistance (>100M ) | Critical for electrical safety |
| Operating Temperature (-20 C to +85 C) | Defines environmental compatibility |
| Insertion Force (0.1-2N) | Impacts user experience and durability |
Primary sectors include: - Consumer electronics (smartphones, toys) - Medical devices (pacemakers, glucose meters) - Industrial equipment (portable analyzers) - Automotive (keyless entry systems) - Renewable energy (solar garden lights)
| Manufacturer | Representative Product | Key Features |
|---|---|---|
| TE Connectivity | 1-1449259 | High vibration resistance for automotive |
| Molex | 47000-002 | Low-profile SMT design |
| Panasonic | EVB-SP | Corrosion-resistant silver plating |
Key considerations: - Battery chemistry compatibility (alkaline/Li-ion) - Current/voltage requirements - Environmental conditions (temperature/humidity) - Mechanical mounting requirements - Agency certifications (UL, RoHS)
Emerging developments include: - Miniaturization for wearable devices - High-temperature resistance materials - Integrated battery management contacts - Eco-friendly plating alternatives - Smart battery interface integration
Case Study 1: Medical glucose meter using PCB mount contacts with 5 " gold plating for 100,000+ connection cycles. Case Study 2: Industrial smoke detector employing vibration-resistant spring clips operating at 85 C for 10-year service life.
