Battery Holders, Clips, Contacts
1. What are the Structural Types of Battery Holders, Clips and Contacts?
1) Battery Holders
Surface Mount (SMT): including low-profile coin battery holders, compact positive and negative contact sheets, etc., suitable for space-constrained PCB designs.
Through-Hole Mount (THM): such as low-profile lithium/alkaline battery holders, suitable for scenarios requiring higher mechanical stability.
Leaf-Spring Contacts: Ensure reliable contact between the battery and the circuit board through a spring structure.
2) Battery Clips
Provide a metal clamping structure for fixing cylindrical batteries (such as AA/AAA) or button batteries, commonly found in portable devices.
3) Contacts
Contains positive and negative contact sheets, mostly made of conductive metals (such as copper alloys), supports surface mounting or welding connections, and ensures low resistance and high current transmission efficiency.
2. What are Battery Holders, Clips and Contacts Used for?
Consumer Electronics: such as button battery holders in smartwatches and remote controls.
Industrial Equipment: Vibration-resistant and high-temperature-resistant battery clips and spring contact designs are required.
Medical Equipment: Use low-profile SMT battery holders to save space.
3. Major Manufacturers of Battery Holders, Clips and Contacts
Keystone Electronics: Provides a variety of SMT/THM battery holders and spring contact solutions.
TE Connectivity: Focuses on high-reliability battery connectors.
KYOCERA AVX: Develops ceramic dielectric contact sheets with excellent high-frequency characteristics.
The selection of such components requires comprehensive consideration of the mounting method (SMT/THM), current load, and environmental adaptability.
