7-PIN Fingerprint Lock Battery Holder Connector 2.0mm Spacing Insert Blade PBT Material Phosphor Bronze Contacts

7-PIN Fingerprint Lock Battery Holder Connector 2.0mm Spacing Insert Blade PBT Material Phosphor Bronze Contacts

Highlight

• 2.0mm pitch 7‑pin insert‑blade battery holder, tailor‑made for fingerprint lock lithium‑battery modules
• Phosphor‑bronze contact beams, stable spring pressure, low contact resistance against vibration & drop‑off disconnection
• UL94‑V0 PBT housing, withstands wave‑soldering thermal shock, anti‑deformation under indoor temperature cycles
• Anti‑mis‑insertion shroud structure, prevents reverse battery assembly damage for smart‑lock mass production lines
• RoHS‑compliant, consistent performance for high‑volume smart‑lock OEM & ODM projects

Product Feature

1. 7‑position, 2.0 mm pitch insert‑blade structure, direct‑insert battery‑blade mating, no extra wire harness needed
2. Phosphor‑bronze C5191 contacts, good spring retention, resists relaxation after thousands of insert‑extract cycles
3. Black PBT housing (UL94‑V0), suitable for wave‑soldering process, dimensional stability under temperature fluctuation
4. Built‑in anti‑mis‑insert shroud, mechanical fool‑proof to avoid reverse battery insertion
5. Through‑hole PCB pins, solid soldering anchoring, anti‑loosening under vibration of door‑lock mechanical movement
6. Optimized contact‑beam geometry, lower heating under continuous power‑supply of smart‑lock standby & motor‑discharge peak current
7. RoHS & REACH compliant, supports large‑batch tray/bag packaging for SMT / through‑hole assembly lines

Product Advantage

1. 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.
2. Phosphor‑bronze spring superiority: Better stress‑relaxation resistance than brass; keeps stable contact performance after long‑term repeated battery replacement.
3. PBT thermal stability: Resists housing warpage during wave‑soldering; avoids pin offset, which leads to poor soldering in mass production.
4. Fool‑proof mechanical design: Shroud anti‑mis‑insert feature cuts assembly‑line defect rate, protects expensive main‑board IC from reverse‑voltage damage.
5. Flexible customization: Support pin‑count adjustment, plating‑thickness modification, special packaging; fast sample turnaround for smart‑lock project validation.
6. 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

1. Confirm pitch: Must adopt 2.0 mm mating blade dimension; do not mix‑use with 2.54 mm pitch battery connectors.
2. Verify pin‑count definition: Confirm 7‑pin signal/power assignment between battery blade and PCB schematic; pin‑out can be customized.
3. Mounting check: This model is through‑hole type; design PCB footprint strictly follows our provided drawing.
4. Plating selection: Standard gold‑plated for smart‑lock indoor environment; enhance gold thickness if used in high‑humidity coastal regions.
5. Current margin: When motor instant peak current occurs, reserve ≥40 % current margin per pin in your design.
6. Assembly note: Rely on built‑in mechanical fool‑proof; do not force‑insert battery blade in reversed orientation.
7. Sample first: Run real‑machine aging & vibration test with samples before mass‑order release.

Step Custom Process

1. Requirement Collection → 2. Technical Evaluation & Quotation → 3. 3D Drawing Review & Confirmation → 4. Mold / Tooling & Prototype → 5. Sample Test (contact R, retention, reflow) & Approval → 6. Mass Production → 7. Final QC & Shipment.
