Battery Terminal Cover Hinge Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage battery connection terminals are difficult to install due to the use of tightening bolts and nuts, often leading to over-tightening, damage to the post terminal, and a complex appearance with potential cover separation issues.
Innovation Solution
A connection terminal design that uses a cover with a hinged structure and interval-keeping members to securely couple the insertion part with the post terminal without separate tightening members, allowing for easy operation and preventing damage from excessive force, while maintaining a simple layout and preventing cover separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If tightening bolts and nuts are used to adjust the diameter of the insertion part, then the connection terminal can be firmly assembled, but the installation becomes difficult and the appearance becomes complicated
Solution Approach 1:
The invention removes the tightening bolts and nuts from the connection terminal structure, extracting the problematic components that caused installation difficulty and complicated appearance. The insertion part is designed to be directly inserted into the cover without requiring separate tightening members, thereby simplifying the assembly process while maintaining firm connection through the integrated structure of the insertion part and cover.
2Stability of the object's composition
If tightening bolts and nuts are used to reduce the diameter of the insertion part, then the connection terminal can be firmly assembled, but the post terminal of the storage battery is damaged due to excessive tightening force
Solution Approach 1:
The insertion part is designed with self-adjusting features that allow it to automatically fit into the cover without requiring external tightening forces. The structure includes complementary shapes and interference fits that enable the insertion part to secure itself within the cover, eliminating the need for bolts and nuts that could apply excessive force and damage the post terminal.
3Ease of operation
If the cover is coupled with the terminal without setting position, then the cover can be easily installed, but the cover may be separated from the terminal and the appearance becomes complicated
Solution Approach 1:
The cover and terminal are designed with asymmetric positioning features, such as non-circular cross-sections or keyed interfaces, that prevent rotational misalignment and separation. The asymmetric shape ensures that the cover can only be installed in the correct orientation, maintaining stable positioning while keeping the installation process simple and tool-free.

AI summary
Disclosed is a connection terminal for a storage battery for coupling the storage battery of a car with a connection wire. The connection terminal includes: a fixing plate having a hole of a predetermined size formed at the center thereof; a fixing member vertically mounted in the hole of the fixing plate; an insertion part mounted at a side of the fixing plate and formed in a round shape opened at a side thereof for inserting a post terminal of the storage battery; a cover for covering the insertion part; and a tightening member for coupling the insertion part with a post terminal of the storage battery by changing a diameter of the insertion part. The tightening member may be formed by tapered walls of the cover, which is connected to the fixing member by a hook or a hinge.
