Segmented Lever Actuator for Compact Conductor Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conductor terminals with lever actuation require additional technical effort and space due to the integration of an actuating lever, which complicates assembly and increases the overall size and cost.
Innovation Solution
A conductor terminal design where the control element and clamping spring actuator element are connected via corresponding fastening elements, allowing for form-fitting and secure positioning, enabling the actuating lever to perform pivoting movements without the need for a complete lever assembly, thus simplifying assembly and reducing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an actuating lever is integrated into a conductor terminal, then lever actuation allows for simple and comfortable operation without separate tools, but additional technical effort and space requirements increase
Solution Approach 1:
The actuating lever is divided into two separate components: a control element and a clamping spring actuator element. These segments can be assembled independently and connected via corresponding fastening elements, reducing the technical effort required for integration while maintaining the lever actuation function.
Solution Approach 2:
The control element and clamping spring actuator element are combined through corresponding fastening elements that enable form-fitting connection and positioning. This merging allows the segmented components to function together as a complete actuating lever system.
2Ease of operation
If an actuating lever is integrated into a conductor terminal, then lever actuation allows for simple and comfortable operation without separate tools, but space requirements increase
Solution Approach 1:
By segmenting the actuating lever into separate components (control element and clamping spring actuator element), the housing can be designed with smaller openings for each component. The control element can be inserted through a first opening while the clamping spring actuator element is inserted through a second opening, reducing the overall space required compared to a complete integrated lever assembly.
3Ease of manufacture
If a complete actuating lever is installed, then the assembly is straightforward, but the space required for inserting the component is larger
Solution Approach 1:
The actuating lever is segmented into separately assemblable components that can be inserted through smaller housing openings. The control element and clamping spring actuator element are connected via corresponding fastening elements, allowing assembly in a simplified sequence that requires less insertion space than a complete integrated lever.
Solution Approach 2:
The control element and clamping spring actuator element are designed with predetermined corresponding fastening elements that guide their connection. This preliminary design of the connection interface simplifies the assembly process, making it straightforward to connect the segments after insertion.

AI summary
A conductor terminal with at least one spring force terminal connection for the connection of an electrical conductor via spring force clamping. The spring force terminal connection has a clamping spring. The conductor terminal has a housing and an actuating lever which is pivotably mounted in a pivoting plane in the housing for actuating the clamping spring. The actuating lever is formed with at least one clamping spring actuator element and at least one control element. The clamping spring actuator element actuates the clamping spring and the control element has at least one handle portion for manually actuating the actuating lever. The control element and the clamping spring actuator element have mutually corresponding fastening elements, via which the control element and the clamping spring actuator element are form-fittingly and/or force-fittingly connected to one another.
