Engineering Bulletin: Dual-Cell AAA Compartment Integration
Ensuring uninterrupted power delivery in multi-cell battery compartments requires precise contact tension and dimensional stability. The Jiatel JT-BC-926 functions as a 1:1 high-reliability mechanical alternative for the legacy Keystone 296 battery contact. Manufactured via precision metal stamping from high-grade spring steel, this snap-on component provides a secure interface for two AAA, AAAA, or N-type cells in series. The leaf spring architecture is engineered to absorb axial battery length variations while maintaining a consistent mating force, preventing electrical disconnects during mechanical shock or vibration.

Metallurgy & Fatigue Resistance
To eliminate contact fatigue degradation and impedance expansion, the JT-BC-926 implements premium industrial-grade alloy boundaries. The primary frame is stamped from high-tensile spring steel, preventing material warping during repeated battery insertion cycles. The entire contact assembly is sealed with a high-density, 200-micro-inch nickel electroplating. This finish delivers exceptional oxidation defense, isolates the base metal from acidic electrolyte fluid leaks, and ensures consistently low contact resistance.
NPI Compartment Layout & SLA Directive
Molded plastic enclosures and automated assembly lines demand zero mechanical distortion to prevent terminal short-circuit risks. Our engineering directive strictly prohibits the deployment of unverified 3D STEP models or 3D CAD files for compartment clearance checks. We execute footprint validation and structural seating audits exclusively through official [Technical Datasheets] and verified [2D Footprint Specs].
To confirm that our snap-on contact precisely matches your plastic compartment injection mold and 1.5mm-1.7mm panel thickness, deploy our Senior NPI Engineering Team. Submit your spatial constraints directly to our technical desk: NPI Engineering Queue
SLA Commitment: Upon form submission to our NPI Engineering Queue, we guarantee the dispatch of matched, production-ready PDF drawings within 12 working hours.
