Integrally Formed Battery Terminal Minimizes Voltage Drop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery terminals often result in voltage drops when connecting electrical components to batteries, particularly in applications like detection circuits, due to inherent electrical resistance in the connection paths.
Innovation Solution
A battery terminal design featuring a terminal body, component terminal, and fusible body formed from a single conductive metal plate, with the component terminal positioned closer to the terminal body than the fusible body to minimize voltage drops, and a fusible body configuration that extends in both the extending and crossing directions to optimize current flow and reduce size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a conventional battery terminal with separate components is used, then the device complexity is reduced and ease of manufacture is improved, but voltage drop increases due to inherent electrical resistance in the connection paths
Solution Approach 1:
The patent merges the terminal body, component terminal, and fusible body into a single integrally formed conductive metal plate structure. This eliminates separate connection paths and reduces electrical resistance at interfaces, thereby suppressing voltage drop between the battery and connected electrical components while maintaining structural complexity at a manageable level
2Loss of energy
If the component terminal is positioned farther from the terminal body, then the fusible body can be shorter and the device size can be reduced, but voltage drop increases due to longer current path
Solution Approach 1:
By integrating the component terminal directly onto the terminal body within the same conductive metal plate structure, the patent minimizes the current path length and eliminates interface resistance. The fusible body is positioned to extend from the terminal body to the circuit terminal, creating an optimized current flow path that reduces voltage drop while maintaining compact overall dimensions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively suppresses voltage drops between the battery and connected electrical components, allowing for accurate detection of residual battery capacity while integrating a fuse for size reduction and enhanced performance.
Implementation Method 1
When the electric current having a current value equal to or larger than a threshold value is flowed, the fusible body 523 is fused to prevent an excessive current from flowing in the circuit
Implementation Method 2
an electric current flows from the battery 6 to the individual circuit terminals 522 through the power supply terminal 521 via the fusible body 523

AI summary
A battery terminal includes a terminal body and a component terminal. The terminal body is connected to a rod-like electrode which projects from a terminal mounting surface of a battery and extends toward an outer periphery of the terminal mounting surface. An external fuse (electrical component) is connected to the component terminal. The terminal body and the component terminal are formed by being cut integrally from a single plate made of a conductive metal.
