Battery Ground Spring Plate for Vibration-Stable Radio Contacts

The patent changes the material parameter from flexible plastic to rigid metal for the lock plate, and changes the contact interface parameter from direct plastic-to-metal contact to spring-mediated contact. This resolves the contradiction by maintaining ease of manufacture through standard metal stamping processes while dramatically improving ground contact stability under vibration and drop conditions through the rigid structure and spring compensation mechanism.

The patent introduces a spring as an intermediary element between the lock plate and the battery ground plate. The spring acts as a mediator that maintains continuous contact pressure, compensating for vibrations and impacts that would otherwise cause intermittent disconnections. This resolves the contradiction by allowing the use of rigid metal lock plates while ensuring stable ground contact through the spring's compensatory action.

The patent changes the lock plate material to rigid metal, which inherently provides better stability without requiring complex additional structures. The simplicity of the rigid lock plate design, combined with the straightforward spring attachment, resolves the contradiction by achieving improved ground contact stability while maintaining relatively simple device construction.

The patent segments the ground contact mechanism into distinct functional components: the rigid lock plate provides structural stability, while the spring provides contact pressure compensation. This segmentation allows each component to be optimized for its specific function, resolving the contradiction by achieving high reliability through functional specialization rather than overall system complexity.

The spring acts as an intermediary that passively accommodates battery ground plate movement through its elastic deformation. This simple mechanical intermediary maintains continuous electrical contact without requiring complex control systems or multiple components, resolving the contradiction by improving power supply consistency through a single, straightforward spring element.

The spring provides self-adjusting contact pressure that automatically compensates for variations in battery ground plate position and movement. This self-service mechanism maintains reliable electrical contact without requiring external control or adjustment, resolving the contradiction by improving power supply consistency through an autonomous, simple elastic element.
