Product Feature
- 7‑position, 2.0 mm pitch insert‑blade structure, direct‑insert battery‑blade mating, no extra wire harness needed
- Phosphor‑bronze C5191 contacts, good spring retention, resists relaxation after thousands of insert‑extract cycles
- Black PBT housing (UL94‑V0), suitable for wave‑soldering process, dimensional stability under temperature fluctuation
- Built‑in anti‑mis‑insert shroud, mechanical fool‑proof to avoid reverse battery insertion
- Through‑hole PCB pins, solid soldering anchoring, anti‑loosening under vibration of door‑lock mechanical movement
- Optimized contact‑beam geometry, lower heating under continuous power‑supply of smart‑lock standby & motor‑discharge peak current
- RoHS & REACH compliant, supports large‑batch tray/bag packaging for SMT / through‑hole assembly lines
Product Advantage
- Smart‑lock‑oriented tuning: Blade‑contact geometry optimized for fingerprint‑lock battery‑swap scenarios; contact‑force tuned to prevent intermittent power cut caused by door‑closing vibration.
- Phosphor‑bronze spring superiority: Better stress‑relaxation resistance than brass; keeps stable contact performance after long‑term repeated battery replacement.
- PBT thermal stability: Resists housing warpage during wave‑soldering; avoids pin offset, which leads to poor soldering in mass production.
- Fool‑proof mechanical design: Shroud anti‑mis‑insert feature cuts assembly‑line defect rate, protects expensive main‑board IC from reverse‑voltage damage.
- Flexible customization: Support pin‑count adjustment, plating‑thickness modification, special packaging; fast sample turnaround for smart‑lock project validation.
- Cost‑performance balance: Factory direct supply; stable quality for mid‑to‑high‑end fingerprint‑lock OEM, no over‑spec redundancy to raise BOM cost.
Application
- Fingerprint smart locks, password access‑control locks (core application)
- Smart door‑lock lithium‑battery packs
- Portable IoT battery‑powered modules
- Home‑security smart devices
- Low‑power smart‑sensor equipment
- Small‑size consumer electronics requiring blade‑type battery connection
Customization Options
- Confirm pitch: Must adopt 2.0 mm mating blade dimension; do not mix‑use with 2.54 mm pitch battery connectors.
- Verify pin‑count definition: Confirm 7‑pin signal/power assignment between battery blade and PCB schematic; pin‑out can be customized.
- Mounting check: This model is through‑hole type; design PCB footprint strictly follows our provided drawing.
- Plating selection: Standard gold‑plated for smart‑lock indoor environment; enhance gold thickness if used in high‑humidity coastal regions.
- Current margin: When motor instant peak current occurs, reserve ≥40 % current margin per pin in your design.
- Assembly note: Rely on built‑in mechanical fool‑proof; do not force‑insert battery blade in reversed orientation.
- Sample first: Run real‑machine aging & vibration test with samples before mass‑order release.
