Interlocking elastic arms on the rear cover and circuit board secure the battery connector, eliminating small screws to simplify assembly.
Insulating members cover battery terminals to direct heat transfer toward cooling air while blocking dust from adhering to the circuit substrate.
Hollow buffers in an insulative cap isolate electrode terminals from external impacts, preventing short circuits while maintaining stable connections.
Inserting the lead into the current collector minimizes coupling thickness, increasing internal volume and battery capacity.
Replacing soldering with mechanical fastening stabilizes the connection and simplifies manufacturing.
