Movable Clamping Spring Leveraging Busbar Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conductor connection contact elements require complex mechanisms or external forces to open the clamping point for electrical conductors, making them less efficient and difficult to actuate.
Innovation Solution
A movable clamping spring element with a spring tongue that uses a bearing support on the busbar piece to pivot and open the clamping point through a leverage effect, allowing for easy and reliable actuation without direct force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex mechanism or external force is used to open the clamping point, then the clamping point can be opened, but the ease of operation deteriorates and the device complexity increases
Solution Approach 1:
The clamping spring element is designed to open the clamping point automatically through its own spring force when the electrical conductor is inserted. The spring tongue pivots about the bearing support, using the conductor insertion itself as the actuating force, eliminating the need for external actuators or complex mechanisms.
Solution Approach 2:
The bearing support acts as an intermediary pivot point that enables the clamping spring element to rotate and open the clamping point. This simple bearing structure mediates between the spring force and the clamping edges, providing a reliable opening mechanism without requiring complex external forces.
2Ease of operation
If a movable clamping spring element with bearing support is used, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The clamping spring element is segmented into distinct functional parts: the spring body, the spring tongue with bearing support, and the clamping edges. This segmentation allows each part to perform its specific function while maintaining overall simplicity. The bearing support is a separate, simple element that enables rotation without adding complex mechanisms.
Solution Approach 2:
The clamping spring element transitions from a static clamping state to a dynamic opening state through simple rotation about the bearing support. This dynamic movement is achieved through the natural spring force and pivot rotation, avoiding the need for complex actuators, motors, or multi-component mechanisms.
3Ease of operation
If direct force application is used to open the clamping point, then the opening action is direct, but the ease of operation deteriorates due to high force requirements
Solution Approach 1:
The bearing support enables rotational movement of the spring tongue, converting linear force application into rotational motion. This curvature-based pivot mechanism allows the spring force to be applied more effectively, reducing the external force needed to open the clamping point compared to direct linear separation.
Solution Approach 2:
The system uses dynamic spring force that automatically adjusts during the opening process. The spring tongue rotates about the bearing support, allowing the spring force to progressively open the clamping point with minimal external intervention, rather than requiring sustained high direct force.
