Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressure contact terminals experience contact failure due to deformation of the pressure contact blade during wire pressure contact work, which is transmitted to the component connections, leading to potential abrasion and failure.
Innovation Solution
A pressure contact terminal design featuring a component clip to clip an electronic component, a pressure contact blade connected by pressure contact, and a step connection that absorbs deformation between the component clip and pressure contact blade at different bottom face heights, preventing displacement to the component clip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pressure contact blade is connected directly to the component connections with a flat form connection, then the structure is simple and easy to manufacture, but the deformation of the pressure contact blade during wire pressure contact work is transmitted to the component connections, causing sliding abrasion and contact failure
Solution Approach 1:
The connection structure is segmented into two distinct levels: a first connection portion connecting the pressure contact blade to a first terminal at a first bottom face height, and a second connection portion connecting the pressure contact blade to a second terminal at a second bottom face height. This segmentation isolates the component connections from the deformation of the pressure contact blade, preventing sliding abrasion while maintaining structural simplicity.
2Device complexity
If the component connections are positioned at the same bottom face height as the pressure contact blade, then the connection structure is compact and simple, but the deformation of the pressure contact blade is easily transmitted to the component connections, causing fine sliding abrasion powder generation and contact failure
Solution Approach 1:
The invention introduces a vertical dimension (height difference) to the connection structure. The first terminal is positioned at a first bottom face height while the second terminal is positioned at a second bottom face height, creating a stepped configuration. This dimensional change effectively isolates the component connections from the deformation path of the pressure contact blade, preventing contact failure without significantly increasing structural complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The step connection effectively absorbs deformation of the pressure contact blade during load, preventing contact failure and abrasion, ensuring reliable electrical connection by isolating the component clip from deformation-induced stress.
Implementation Method 1
when the pressure contact blade is moved (deformed) by load during wire pressure contact work, the movement (deformation) is absorbed by a step connection

AI summary
A pressure contact terminal includes a component clip configured to clip an electronic component and be electrically connected with the electronic component, a pressure contact blade to be connected with a wire by pressure contact, and a step connection configured to connect the component clip and the pressure contact blade to each other at different bottom face heights. The step connection of the pressure contact terminal may prevent displacement of the pressure contact blade from being transmitted to the component clip.
