Battery Connector Width Reduction via Rear Wire Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery connectors have a widened width dimension due to the extension of wire guides in the width direction of the terminal fixing part, which is not compact and efficient.
Innovation Solution
The battery connector design includes a case with a terminal fixing part and an insulating cover that forms a wire guide on its outer surface in the closing position, featuring a completely-locking cover to restrict the insulating cover's displacement and a temporarily-locking cover to enhance workability, thereby reducing the width dimension and preventing wire guide exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wire guides are extended in the width direction of the terminal fixing part, then wire routing is facilitated, but the width dimension of the battery connector is enlarged
Solution Approach 1:
The wire guide is repositioned from extending in the width direction to extending in the length direction of the terminal fixing part. This dimensional change allows wire routing functionality to be maintained while avoiding enlargement of the width dimension, thus resolving the contradiction between ease of wire routing and compact width.
2Reliability
If the insulating cover is made movable to cover the terminal fixing part, then safety against short-circuits is improved, but device complexity increases
Solution Approach 1:
The insulating cover is designed as a movable component that can be opened and closed to cover the terminal fixing part. This dynamic structure provides safety against short-circuits when closed while allowing access when opened, maintaining reliability without excessive complexity through simple hinge and latch mechanisms.
Solution Approach 2:
The case is divided into a terminal fixing part and a movable insulating cover. This segmentation allows the cover to be independently operated to provide safety coverage, separating the protective function from the fixed structural components and reducing overall device complexity.
3Reliability
If locking covers are added to restrict insulating cover displacement, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking cover is designed as a movable component that can be opened and closed to cover the terminal fixing part. This dynamic structure provides safety against short-circuits when closed while allowing access when opened, maintaining reliability without excessive complexity through simple hinge and latch mechanisms.
Solution Approach 2:
The case is divided into a terminal fixing part and a movable insulating cover. This segmentation allows the cover to be independently operated to provide safety coverage, separating the protective function from the fixed structural components and reducing overall device complexity.

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; and a case which contains the plurality of terminals therein. The case includes a terminal fixing part in which the plurality of terminals are fixed, and an insulating cover which is supported to be displaced to a closing position at which an open face of the terminal fixing part is covered by the insulating cover. A wire guide is formed in an outer surface of the insulating cover in the closing position.
