AA Female Battery Contact (Leaf Spring) | Direct Footprint Replacement for Keystone 5205

Direct Chassis Mount Replacement for Keystone 5205

We engineered this slide-in negative (female) leaf spring contact to accelerate assembly line integration. Serving as a 1:1 mechanical replacement for the Keystone 5205, it secures AA standard cells within molded plastic compartments without requiring manual soldering.

  • Mounting Architecture: Slide-In / Chassis Mount
  • Terminal Function: Negative Cathode (Folded Leaf Spring)
  • Cell Compatibility: 1 x AA Cell
  • Dimensional Envelope: 7.62 mm Width x 13.00 mm Height
  • Retention Feature: 2-1.27 mm side engagement barbs
  • Core Metallurgy: T=0.30 mm Spring Steel
  • Surface Plating: High-Density Nickel Plated

Hardware Integration: AA Leaf Spring Contact

Streamlining device manufacturing requires components that eliminate secondary soldering operations. The JIATEL JT-BC-AA-KS5205 is designed as an exact footprint replacement for the Keystone 5205. This slide-in negative contact allows hardware engineers to execute rapid, tool-less insertion into standard molded battery compartments, drastically reducing assembly time while maintaining robust mechanical retention.

NPI Engineering Protocol: Plastic chassis tolerances dictate the success of slide-in contacts. We strictly prohibit the distribution of unverified 3D digital layouts to prevent severe mold interference errors. To confirm a 1:1 replacement fit, you must engage our Senior NPI Engineering Team. Forward your compartment parameters to our NPI Engineering Queue. We execute structural validation exclusively through official [Technical Datasheets] and [2D Footprint Specs], dispatched within 12 working hours.

Technical Data & Metallurgy

Our test data shows that constant vibration degrades terminal connections. We mitigate this by forming the JT-BC-AA-KS5205 from T=0.30 mm Spring Steel. The folded leaf spring design generates sustained compression against the AA cathode, while the 2-1.27 mm lateral barbs bite aggressively into the plastic housing to prevent back-out.

  • Base Profile: 7.62 mm (W) x 13.00 mm (H)
  • Internal Clearance: 11.10 mm leaf height
  • Base Material: Spring Steel (High fatigue resistance)
  • Conductive Plating: Nickel Plated (Low contact resistance)

Validated Application Sectors

This chassis-mount contact is heavily deployed in products utilizing UL 94V-0 rated plastic housings:

  • Industrial IoT: Rugged sensor enclosures requiring secure AA battery retention without PCB soldering.
  • Consumer Electronics: Handheld motorized devices and heavy-duty remote controls.
  • Medical Instruments: Portable diagnostic tools demanding reliable spring tension over thousands of use cycles.
