Spring Clamp Terminal with Auto-Release Conductor Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for electrical conductors, particularly those with flexible conductors, require manual actuation of a clamping spring to pivot the clamping leg away from the current bar, making installation cumbersome and time-consuming.
Innovation Solution
A connection arrangement with a clamping spring and a trigger element that allows flexible conductors to be easily connected by pivoting the clamping leg into an open position using an actuating element, which is held in place by a trigger element, and automatically returns to a clamping position upon conductor insertion, facilitated by a spring mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual actuation of the actuating element is required to pivot the clamping spring into the open position for inserting flexible conductors, then the conductor can be inserted into the connection arrangement, but the installation process becomes cumbersome and time-consuming
Solution Approach 1:
The clamping spring is pre-configured in an open position during assembly, allowing the conductor to be inserted without requiring manual actuation. The trigger element is preliminarily set to release the clamping spring automatically when the conductor is inserted, eliminating the need for separate manual actuation steps and reducing installation time
2Ease of operation
If the clamping spring is held in the open position by the trigger element during conductor insertion, then the conductor can be easily inserted, but additional components and complexity are introduced to the connection arrangement
Solution Approach 1:
The trigger element is integrated with the clamping spring assembly, forming a combined unit where the trigger element is mounted on the clamping spring. This merging reduces the number of separate components and simplifies the overall structure while still providing the automatic release function during conductor insertion
