Conductor Connection Terminal Manual Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductor connection terminals with spring-loaded clamping connections require external tools for actuation, which complicates the process and exposes internal components to environmental influences.
Innovation Solution
A conductor connection terminal with a manual actuating element and a movably mounted control element, where the actuating element has a restoring contour to facilitate opening and closing of the clamping point without external tools, ensuring the control element remains encapsulated and protected, and the clamping spring provides restoring force for reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual actuating element with restoring contour is used, then the clamping point can be actuated without external tools, but the device complexity increases due to additional contours and control elements
Solution Approach 1:
The restoring contour and actuating contour are integrated into the actuating element itself, merging the actuation function and restoring function into a single component. This eliminates the need for separate external tools while avoiding the complexity of multiple independent mechanisms.
Solution Approach 2:
The actuating element performs both the actuation of the clamping point and its own restoration to the initial position through the restoring contour. The control element is moved by the actuating element itself during the actuation process, creating a self-contained system that operates without external intervention.
2Object-affected harmful factors
If the control element is encapsulated within the housing, then internal components are protected from environmental influences, but the ease of operation may be reduced due to limited access
Solution Approach 1:
The control element is nested within the housing, with the actuating element providing access to the control element through the housing structure. This allows the control element to be protected while still enabling operation through the integrated actuating mechanism that interacts with the control element via the restoring and actuating contours.
3Reliability
If the clamping spring provides restoring force, then the reliability of the clamping connection is improved, but the force required to open the clamping point increases
Solution Approach 1:
The clamping spring provides dynamic restoring force that automatically adjusts to maintain reliable clamping. The spring force is optimized to provide sufficient holding force while the actuating element with restoring contour distributes the opening force over a controlled path, reducing the peak force requirement compared to a purely mechanical latch system.
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
Enables actuation of the clamping point without external tools, protects internal components from environmental factors, and ensures reliable operation with defined end positions, enhancing user safety and device durability.
Implementation Method 1
The clamping spring can exert a restoring force on the control element at least in some areas, by means of which the restoring movement of the control element from the open position to the closed position caused by the restoring contour is supported at least in some areas.

AI summary
A conductor connection terminal with at least one spring-loaded clamping connection for connecting an electrical conductor via a spring-loaded clamping. The spring-loaded clamping connection has at least one clamping point for clamping the electrical conductor which is formed with a clamping leg of a clamping spring. The conductor connection terminal has a manual actuating element which, as a result of manual actuation, can be moved from at least a closed position, in which the clamping point is closed, to an open position, in which the clamping point is open, and vice versa. The conductor connection terminal comprises a movably mounted control element by means of which the manual actuating element is mechanically coupled to the clamping spring, so that, as a result of manual actuation of the manual actuating element, the clamping point can be opened and closed via the control element.
