Fuse Base Terminal Connection Assembly with Universal Fastener Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection assemblies for fuse base connection terminals only allow users to choose between using a nut or a bolt for connection, limiting flexibility.
Innovation Solution
A connection assembly featuring a base with a connection terminal and a support piece that can accommodate either a nut or a bolt, with a hexagonal accommodation groove and through hole, allowing for secure and flexible attachment options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a nut or bolt is directly connected to the connection terminal, then the connection is secure, but the user cannot choose between different connection methods
Solution Approach 1:
The connection assembly is divided into separate functional components: a support piece with accommodation groove for receiving fasteners, and a connection terminal with connection hole. This segmentation allows the support piece to be designed as a universal interface that can accommodate different fastener types (nuts or bolts) while maintaining a simple overall structure.
Solution Approach 2:
The support piece with accommodation groove serves multiple functions: it can receive and secure either a nut or a bolt, providing universal compatibility. The accommodation groove is designed with sufficient space and appropriate geometry to accommodate different fastener types, enabling users to choose their preferred connection method without requiring different connection assemblies.
2Ease of operation
If a support piece with accommodation groove is added to enable choice between nut and bolt, then user flexibility is improved, but the device structure becomes more complex
Solution Approach 1:
The support piece combines multiple functions into a single component: it provides structural support, contains the accommodation groove for fastener reception, and interfaces with the connection terminal. By merging these functions into one integrated piece, the design avoids the need for separate mounting brackets, fastener holders, and connection interfaces, thereby simplifying the overall structure while maintaining user flexibility.
Solution Approach 2:
The accommodation groove is designed to self-accommodate different fastener types through its geometric design. The groove provides sufficient space and appropriate contours that naturally guide and secure both nuts and bolts without requiring additional adjustment mechanisms or complex positioning features, enabling user choice while maintaining structural simplicity.

AI summary
A connection assembly for a fuse base connection terminal (2) comprises a base (1) and a connection terminal (2) arranged on the base (1). A connection hole (21) is arranged on the connection terminal (2). The connection assembly also comprises a support piece (3) plugged into the connection terminal (2). The support piece (3) comprises an accommodation groove (31) used for accommodating a nut (4) or a bolt (5). A side surface of the accommodation groove (31) is provided with an opening (32). A bottom of the accommodation groove (31) is provided with a through hole (37). A position corresponding to the support piece (3) on the base (1) is provided with a bolt mounting hole (11). The bolt mounting hole (11), the connection hole (21) and the through hole (37) are on the same axis. Because the support piece (3) that can be plugged into the connection terminal (2) is arranged and the nut (4) or the bolt (5) can be put into the support piece (3), a user is free to choose to put the nut (4) or the bolt (5) into the support piece (3) to connect of the connection terminal (2) to a cable.
