Insulated Battery Clamp Structure for Reliable Cable Connection

The patent implements a nested clamp structure where an inner clamp is positioned within an outer clamp. The inner clamp provides primary electrical connection, while the outer clamp provides additional mechanical support and insulation. This nested arrangement enhances connection reliability through multiple contact points and redundant support structures without requiring entirely separate clamp systems.

The patent employs composite material construction by combining conductive materials for the inner clamp (for optimal electrical contact) with insulating materials for the outer clamp (for safety and protection). This composite approach allows each component to be optimized for its specific function, improving overall connection reliability while maintaining reasonable device complexity.

The spring mechanism is designed to automatically engage and disengage the clamp from the battery terminal. When the clamp is approached to the terminal, the spring automatically provides the necessary clamping force and secures the connection without requiring manual adjustment or additional fastening operations. This self-service mechanism significantly improves ease of operation during battery connections and disconnections.

The snap-fit connection acts as an intermediary mechanism between the user's manual operation and the final clamping action. The snap-fit features provide audible and tactile feedback that confirms proper engagement, serving as a mediator that ensures correct installation without requiring complex alignment procedures or multiple adjustment steps.

The clamp device is segmented into two distinct components: an inner conductive clamp for electrical contact and an outer insulating clamp for safety and structural support. This segmentation allows each component to be manufactured using material and processes optimized for its specific requirements, with the inner clamp focused on electrical conductivity and the outer clamp on insulation properties and mechanical strength.

The outer insulating clamp serves multiple functions simultaneously: it provides electrical insulation for safety, structural support for the overall assembly, and protection for the inner conductive clamp. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in manufacturing complexity while achieving improved operational safety.
