Voltage Detection Terminal Housing for Easier Plate Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In stacked power storage devices, the existing method of connecting a detection terminal to a conductive plate is cumbersome due to the thin plate shape, leading to complex position alignment and reduced workability.
Innovation Solution
A voltage detection unit with a voltage detection terminal and a plate-shaped housing that includes a terminal accommodating concave and a cover, allowing for temporary and final locking positions to facilitate easy connection and protection of the terminal, while an electric wire is drawn out from the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection terminal is inserted into the insertion hole of the conductive plate from the side of the stacked body, then the connection can be established, but the position alignment becomes complicated and workability deteriorates
Solution Approach 1:
The detection terminal is pre-installed in the housing before the conductive plate is placed, allowing the connection interface to be prepared in advance. This eliminates the need for complex position alignment during assembly, as the terminal is already positioned correctly to receive the conductive plate's contact portion.
Solution Approach 2:
The housing acts as an intermediary structure that holds the detection terminal in a fixed position and provides a standardized interface for the conductive plate. This mediator structure simplifies the connection process by transforming the complex alignment requirement into a simple insertion operation.
2Reliability
If the cover covers the first portion of the voltage detection terminal at the final locking position, then the terminal is protected, but the connection area is reduced
Solution Approach 1:
The cover is designed with an opening that segments the covering function, allowing it to protect the housing and second portion of the terminal while leaving the first portion (connection area) exposed. This segmentation enables simultaneous achievement of protection and connection accessibility.
Solution Approach 2:
The cover provides localized protection only where needed (the housing and second portion of the terminal) while leaving the connection area (first portion) uncovered. This local quality approach ensures protection is applied selectively without unnecessarily reducing the connection area.

AI summary
A voltage detection unit includes a voltage detection terminal including a first portion configured to be conductively connected to a detection target and a second portion, a housing having a plate shape and including a terminal accommodating concave configured to accommodate the voltage detection terminal, a cover configured to be engaged with the housing at a temporary locking position at which the cover does not cover the first portion of the voltage detection terminal accommodated in the terminal accommodating concave and at a final locking position at which the cover covers the first portion and an electric wire conductively connected to the voltage detection terminal at the second portion and configured to, when the voltage detection terminal is accommodated in the terminal accommodating concave, be drawn out from the housing.
