Conductor Terminal Actuating Element Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conductor terminals suffer from undesirable interactions between the connection area for electrical conductors and the lever movement area, leading to inefficiencies and potential damage.
Innovation Solution
A conductor terminal design with a pivotably mounted actuating element that separates the connection area and lever movement area, using a clamping spring with a curvature to reduce stress and eliminate the need for additional fixing elements, and incorporating a self-locking mechanism to maintain the open position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional connector with separate contact and housing is used, then assembly is straightforward, but the connector has large dimensions and poor high-frequency signal transmission characteristics
Solution Approach 1:
The patent integrates the contact and housing into a single integrated connector structure. The contact is directly formed on the housing body, eliminating the need for separate assembly steps. This merging of components reduces the overall connector size while simplifying the manufacturing process by reducing the number of parts and assembly operations required.
2Object-affected harmful factors
If shielded cables with connected shields are used, then electromagnetic shielding is improved, but the connector dimensions increase and high-frequency signal transmission deteriorates
Solution Approach 1:
The patent introduces a ground contact as an intermediary element between the signal contact and the housing. This ground contact provides a dedicated reference potential that improves electromagnetic shielding effectiveness without requiring direct connection of shields that would increase connector dimensions. The intermediary ground contact maintains signal integrity at high frequencies while providing necessary shielding.
3Volume of moving object
If connector components are tightly fitted to reduce size, then compactness is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The patent segments the connector into distinct functional regions: the housing body, the ground contact extending from the housing, and the signal contact. This segmentation allows each component to be manufactured with standard tolerances and then assembled together, reducing the overall manufacturing precision requirements while maintaining a compact form factor. The modular design enables easier quality control and manufacturing.
