Battery Post Terminal Assembly With Deformation-Restraining Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery post terminal assemblies face issues with deformation due to excessive torque or the use of rust-proof oil during fastening, leading to instability.
Innovation Solution
The battery post terminal assembly incorporates projection portions on the base member that contact the fastening portion, along with a stepped screw shaft and projection portions to restrain deformation by limiting movement and providing balanced fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fastening structures are used with rust-proof oil, then ease of operation is improved, but manufacturing precision deteriorates due to deformation
Solution Approach 1:
The invention applies preliminary anti-action by designing the projection portion to preemptively counteract the deforming force generated during fastening. The projection portion is positioned to contact the fastening portion before excessive deformation occurs, creating a restraining force that opposes the outward deformation caused by rust-proof oil and excessive torque, thereby preventing precision loss while maintaining ease of operation
2Strength
If excessive torque is applied during fastening, then strength is improved, but manufacturing precision deteriorates due to deformation
Solution Approach 1:
The projection portion serves as a preliminary anti-action mechanism that counteracts the deforming effect of excessive torque before it causes precision loss. By contacting the fastening portion and restraining its outward movement, the projection portion allows strong fastening while preventing the torque-induced deformation that would compromise manufacturing precision
3Ease of operation
If the fastening portion is allowed to move freely during fastening, then ease of operation is improved, but reliability deteriorates due to unstable fastening
Solution Approach 1:
The invention applies local quality by creating a localized constraint at the projection portion that specifically targets the fastening portion's movement. This localized intervention restricts freedom of movement only where needed to prevent deformation, while allowing the rest of the fastening operation to proceed freely, thereby maintaining ease of operation while improving reliability through stable, deformation-free fastening

AI summary
A battery post terminal is restrained from deforming more than necessary. A battery post terminal assembly (1) includes a battery post terminal (10) including a grasping portion (21) capable of grasping a battery post on an inner side, and a fastening portion (31) placed in a form of a pair to extend from end portions of the grasping portion, a holder (40) placed on one side of the fastening portion (31), and a base member (50) placed on an opposite side to the holder (40) with the fastening portion (31) between the holder(40) and the base member (50). The base member (50) has a base seat portion (52), a screw shaft (51) that is provided on one surface of the base seat portion (52) to be coupled to the holder (40), and a projection portion (54) that is provided on a surface having the screw shaft (51) of the base seat portion (52), and to project to an inner side of the fastening portion (31) when coupled to the holder (40).
