Phosphor bronze coil springs

Phosphor bronze coil springs

Primary Applications
Our phosphor bronze coiled spring contacts, renowned for their outstanding comprehensive performance, are widely utilized in applications requiring elastic contact, electrical conductivity, cushioning, or positioning:

Electrical Connectivity (Primary Application):

Battery Connectors: Used in portable devices such as mobile phones, Bluetooth headsets, smartwatches, and laptops to connect battery terminals, providing stable and durable elastic contact withstanding repeated insertion/removal.

Board-to-Board Connectors: Serve as contact points between circuit boards, compensating for mounting tolerances to ensure reliable electrical conductivity.

Switch Contacts: Function as resilient contact components within switches, offering extended lifespan and low contact resistance.

SIM Card Holders, Memory Card Holders: Internal spring contacts ensure secure contact after card insertion.

Mechanical Applications:

Axial or Radial Buffering: Used in precision instruments, optical equipment, motors, etc., as miniature damping washers to absorb vibration and noise.

Clearance Adjustment and Preload: Eliminates minute gaps in transmission components like gears and bearings, preventing loosening.

Elastic Support and Positioning: Provides flexible support for small components while allowing limited movement.

Other Applications:

Electromagnetic Shielding: Leveraging elasticity and conductivity, they serve as grounding contacts on shielding chambers or covers to ensure effective electromagnetic sealing.

Thermal Conductivity: In areas requiring heat dissipation where gaps exist, elastic contact improves thermal transfer efficiency.
