Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conductor connection terminals face challenges in preventing conductors from being routed past their intended clamping points and ensuring reliable guidance, especially when inserted at angles, which complicates manufacturing and assembly, and increases costs due to the need for specially formed busbars and clamping springs.
Innovation Solution
A conductor connection clamp with a projection on the housing cover that forms a partition between clamping points, made of insulating material, which guides conductors reliably and separates clamping points, allowing for simpler manufacturing and assembly with fewer parts, using standard busbars and clamping springs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductors are inserted at angles or without precise alignment, then conductor guidance becomes unreliable and conductors may contact wrong clamping points, but adding complex guidance structures increases device complexity and manufacturing costs
Solution Approach 1:
The patent introduces an insulating projection as an intermediary element that forms a partition wall between clamping points. This projection acts as a mediator to guide conductors into the correct clamping point without requiring complex active control mechanisms. The projection is integrally formed with the housing cover, providing passive geometric guidance that prevents conductors from reaching wrong clamping points even when inserted at angles.
2Reliability
If partitions between clamping points are formed using conductive materials like busbars, then electrical separation is achieved, but manufacturing complexity and cost increase due to specialized forming requirements
Solution Approach 1:
The patent replaces expensive, specially-formed conductive partitions with a simple insulating projection that is integrally formed with the housing cover. This projection serves as a sufficient barrier to prevent electrical contact between conductors at different clamping points, eliminating the need for complex conductive partition manufacturing while maintaining safety and reliability.
Solution Approach 2:
The insulating projection serves as an intermediary barrier between clamping points, providing electrical separation through its insulating material properties rather than requiring conductive materials. This mediator approach simplifies manufacturing while achieving the same electrical isolation function.
3Adaptability or versatility
If multiple separate components are used for housing, clamping springs, and partitions, then assembly flexibility is improved, but assembly time and manufacturing costs increase
Solution Approach 1:
The patent merges the partition function with the housing cover by integrally forming the insulating projection directly onto the housing cover. This combination eliminates the need for separate partition components and their associated assembly steps, reducing assembly time and complexity while maintaining the necessary electrical separation and conductor guidance functions.
