Battery Connector with Inclined Voltage Detection Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery connectors are bulky due to protruded wire connection parts, which hinder compactification and require tight folding of electric wires, increasing the risk of short-circuits and making them less efficient for use in compact power supplies like electric vehicles.
Innovation Solution
A battery connector design with inclined voltage detection terminals and individual wire paths between terminals, allowing the wire connection parts to be positioned more interiorly, reducing the connector's width and enabling loose folding of electric wires, thereby achieving a more compact size and improved safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voltage detection terminals are positioned protrudingly for easy wire connection, then wire connection ease is improved, but connector width increases and compactness deteriorates
Solution Approach 1:
The wire connection part is repositioned from a protruding position to an interior position along the width direction, and wire guidance is achieved through a groove structure in the longitudinal direction. This dimensional reconfiguration allows the connector to maintain compact width while enabling easy wire connection through the groove-guided routing path.
Solution Approach 2:
A wire guidance groove is introduced as an intermediary structure between the voltage detection terminal and the external wire connection point. This groove mediates the wire routing, allowing the wire connection part to be positioned interiorly while still providing guided access for wire connection, thus resolving the conflict between compactness and ease of connection.
2Ease of operation
If wire connection parts are positioned protrudingly, then wire access is improved, but wire folding becomes tight and short-circuit risk increases
Solution Approach 1:
The wire guidance groove acts as an intermediary structure that provides a controlled routing path for electric wires. This groove allows wires to be guided smoothly from the interior wire connection part to the exterior, preventing tight folding and reducing short-circuit risk while maintaining easy wire access.
Solution Approach 2:
Wire routing is transitioned from a tight fold in the width direction to a guided path along the longitudinal direction through the groove. This dimensional change in wire routing allows sufficient wire length and loose folding, eliminating short-circuit risks while maintaining accessible wire connection.
3Area of stationary object
If wire connection parts are positioned interiorly, then connector compactness is improved, but wire connection ease deteriorates
Solution Approach 1:
The wire guidance groove serves as an intermediary structure that bridges the interior wire connection part and the exterior wire access point. Although the wire connection part is positioned interiorly for compactness, the groove provides a guided routing path that maintains ease of wire connection by directing wires smoothly to the connection point.
Solution Approach 2:
The wire connection accessibility is maintained not in the width direction (where compactness is achieved) but in the longitudinal direction through the groove. This dimensional shift allows the connector to be compact in width while preserving easy wire connection through the extended groove path.
4Measurement precision
If multiple voltage detection terminals are added for comprehensive voltage monitoring, then detection completeness is improved, but device complexity increases
Solution Approach 1:
Multiple voltage detection terminals are integrated into a single connector body structure, sharing common mounting features and wire guidance grooves. This merging approach allows comprehensive voltage monitoring across multiple batteries while avoiding proportional increases in overall structural complexity, as the terminals utilize shared structural elements.
Solution Approach 2:
The connector structure is designed with universal features that serve multiple voltage detection terminals simultaneously, such as common mounting holes, standardized groove patterns, and shared insulation structures. This multi-functionality allows comprehensive voltage monitoring without each terminal requiring dedicated complex structural elements.

AI summary
A battery connector includes: a plurality of terminals, each of which is to be connected to each electrode of a plurality of batteries; a plurality of voltage detection terminals, each of which is connected to respective one of the terminals, and includes a wire connection part to be connected to an electric wire; and a case which contains the plurality of terminals and the plurality of voltage detection terminals therein. Adjacent terminals of the terminals are fixed in the case to be spaced from each other, and an individual wire path of a wire routing part is provided between the adjacent terminals. Each of the voltage detection terminals is fixed so as to incline the wire connection part with respect to the individual wire path and to locate the wire connection part more interiorly than an edge of the case.
