Screwless Terminal Clamping with Separating Plate Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation switching devices with screwless terminal connections can accidentally jam flexible conductors between clamping legs, leading to incorrect insertion and reduced operational safety.
Innovation Solution
The clamping legs are separated by a slot with a separating plate that guides between them, preventing conductors from being inserted at an angle and ensuring they cannot become jammed, and the design allows for independent movement of the clamping legs to prevent incorrect wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screwless terminal connection with clamping legs is used, then ease of operation is improved, but reliability deteriorates due to conductor jamming
Solution Approach 1:
A separating plate is introduced as an intermediary element between the clamping legs. This plate prevents conductors from becoming jammed between the legs while still allowing the clamping mechanism to function properly. The separating plate acts as a mediator that eliminates the harmful effect of conductor entrapment without compromising the ease of connection.
2Manufacturing precision
If clamping legs are positioned close together, then manufacturing precision is improved, but reliability worsens due to conductor entrapment risk
Solution Approach 1:
The terminal connection space is segmented by introducing a separating plate that divides the area between clamping legs. This segmentation prevents conductors from slipping into the space between legs while maintaining the precise positioning of the clamping mechanism. The separation creates distinct zones that eliminate the entrapment hazard.
3Reliability
If a separating plate is added to prevent conductor jamming, then reliability is improved, but device complexity increases
Solution Approach 1:
The separating plate is designed to serve multiple functions: it prevents conductor jamming, guides conductor insertion, and maintains the structural integrity of the terminal connection. By making this single element multi-functional, the overall device complexity is minimized while still achieving the reliability improvement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances operational safety by preventing conductor jamming and ensuring correct wiring, as the separating plate and slot configuration prevent conductors from being clamped incorrectly, allowing them to slide through instead.
