Battery Connector Contact Layout for False Plug Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors in batteries and power consuming apparatuses lack effective mechanisms to detect and prevent false plugging, which can lead to safety hazards such as short-circuiting and overheating, and current solutions are complex and unreliable.
Innovation Solution
A connector design featuring male and female terminals with varying conductive contact distances, where the second conductive contact distance is smaller than the first, allowing for early detection of improper plugging through the second loop, thereby enhancing safety by monitoring the plug state in real time.

Engineering Contradiction Analysis
1Reliability
If traditional connectors with uniform conductive contact distances are used, then the structure is simple, but false plugging cannot be detected early leading to safety hazards
Solution Approach 1:
The connector is segmented into multiple independent loops (first loops and second loops) with different conductive contact distances. Each loop functions independently for detection purposes, allowing the system to monitor plug insertion status through multiple pathways with varying sensitivity thresholds.
Solution Approach 2:
Different portions of the connector (first plug pins vs second plug pins) are given different local qualities in terms of conductive contact distance. The second loops have shorter conductive contact distances compared to first loops, creating localized detection zones with different thresholds for detecting plug insertion status.
2Reliability
If monitoring mechanisms are added to detect false plugging, then safety is improved, but the device complexity increases
Solution Approach 1:
The connector performs self-monitoring through its inherent multi-loop structure. The different conductive contact distances create natural detection capabilities without requiring external sensors or complex monitoring electronics. The system uses its own structural characteristics to detect and report plug insertion status.
Solution Approach 2:
The multi-loop structure provides inherent feedback mechanisms where the electrical continuity of each loop indicates the insertion status. By comparing the states of first loops and second loops, the system can detect false plugging conditions and provide feedback about the connector's operational status.

AI summary
Embodiments of the present application provide a connector, a device, a battery, and a power consuming apparatus. The connector includes a male terminal and a female terminal, where the male terminal includes M first plug pins and N second plug pins, and the female terminal includes M first jacks and N second jacks, with M and N being positive integers; and when plugging of the male terminal and the female terminal is in place, the M first plug pins are respectively plugged into the M first jacks to form M first loops, and the N second plug pins are respectively plugged into the N second jacks to form N second loops, with a second conductive contact distance (L2) between each second plug pin and the corresponding second jack being smaller than a first conductive contact distance (L1) between each first plug pin and the corresponding first jack.
