Spring Clamp Terminal Assembly for Small Flexible Conductors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements struggle to simplify the connection of flexible conductors and those with small conductor cross-sections, as they require sufficient force to release the clamping spring from the open position, which can be difficult to achieve.
Innovation Solution
A connection arrangement featuring two separate actuating elements, where the first element transfers the clamping spring from the clamping position to the open position, and the second element releases it from the open position, allowing for easier connection of flexible or small conductors without relying on compressive force from the conductor itself.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single actuating element is used to transfer the clamping spring from clamped to open position, then the device complexity is reduced, but the ease of operation deteriorates when connecting flexible conductors with small cross-sections
Solution Approach 1:
The single actuating element is divided into two separate actuating elements: a first actuating element (119) that transfers the clamping spring from clamped to open position, and a second actuating element (128) that releases the clamping spring from the open position. This segmentation allows each element to perform a specific function, making the connection of flexible conductors easier without significantly increasing overall device complexity.
2Reliability
If the clamping spring is held in open position by a locking mechanism, then the reliability of the open position is improved, but the ease of operation deteriorates when manual force is required to close the locking leg
Solution Approach 1:
The second actuating element (128) acts as an intermediary tool that assists the user in releasing the locking leg (116) from the holding contour (127). Instead of requiring direct manual force on the locking leg, the second actuating element provides mechanical leverage and guidance, making the closing operation easier while maintaining the reliable holding of the open position through the locking mechanism.

Function Achieved in This Case
Facilitates easier handling and connection of flexible or small conductors by allowing the clamping spring to be released from the open position using the second actuating element, eliminating the need for manual force to close the locking leg and enabling tool-free connection.
