Multi-Wire Conductive Terminal with Staggered Clamping Widths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductive terminals with clamping arms designed to connect multiple wires face issues where the clamping portion is propped open when engaging subsequent wires, leading to impaired electrical connections and increased costs due to the need for multiple terminals and increased space usage.
Innovation Solution
A conductive terminal with a unique design featuring a first pair of clamping arms forming a first clamping portion and a second pair forming a second clamping portion, both with sub-portions and transition segments arranged along the length direction, where the widths of the sub-portions and transition segments are strategically varied to provide the necessary clamping force without being propped open, ensuring effective electrical connections with multiple wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single conductive terminal with clamping arms is used to connect multiple wires, then the number of terminals and space occupied is reduced, but the clamping portion is propped open when clamping multiple wires, impairing the electrical connection
Solution Approach 1:
The clamping portion is divided into multiple clamping sub-portions (first clamping sub-portion, second clamping sub-portion, third clamping sub-portion, fourth clamping sub-portion) with different widths arranged along the length direction. Each sub-portion is designed to clamp a specific wire, preventing the entire clamping portion from being propped open while maintaining reliable electrical connections for all connected wires.
2Productivity
If the clamping portion is designed to clamp multiple wires simultaneously, then productivity is improved, but the clamping arms are propped open by subsequent wires, reducing manufacturing precision of the electrical connection
Solution Approach 1:
Different clamping sub-portions are designed with different widths to provide locally optimized clamping forces. The first and third clamping sub-portions have different widths than the second and fourth clamping sub-portions, allowing each sub-portion to apply the appropriate clamping force for its specific wire while preventing interference with other wires being clamped subsequently.

AI summary
A conductive terminal includes a first pair of clamping arms forming a first clamping portion for connecting with a wire, and a second pair of clamping arms connected to the first pair of clamping arms by a connecting part. The first clamping portion has a first clamping sub-portion and a second clamping sub-portion distributed along a length direction. The second pair of clamping arms forms a second clamping portion. The second clamping portion has a third clamping sub-portion and a fourth clamping sub-portion distributed along the length direction. The first clamping sub-portion corresponds to the third clamping sub-portion in the length direction. A width of the first clamping sub-portion is greater than a width of the third clamping sub-portion. The second clamping sub-portion corresponds to the fourth clamping sub-portion in the length direction. A width of the second clamping sub-portion is less than a width of the fourth clamping sub-portion.
