Connection Clamp Layout for Tool-Free Conductor Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for electrical conductors require manual actuation to release the clamping spring for flexible conductors, making the process cumbersome and requiring additional tools.
Innovation Solution
A connection arrangement featuring a clamping spring with a retaining leg and a pivoting clamping leg, a guide element to hold the clamping leg in a release position, and a pivotably mounted actuating element to displace the guide element, allowing the clamping leg to be transferred from a clamping position to a release position without direct user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual actuation is used to release the clamping spring for flexible conductors, then the conductor can be inserted, but the process becomes cumbersome and requires additional tools
Solution Approach 1:
The connection arrangement enables self-service operation where the actuating element automatically actuates the clamping spring during the conductor insertion process itself. The insertion movement of the conductor directly triggers the release mechanism through the guide element, eliminating the need for separate manual actuation steps and additional tools.
Solution Approach 2:
The guide element is pre-positioned to engage with the actuating element before conductor insertion begins. This preliminary arrangement ensures that when the conductor is inserted, the actuating element is automatically triggered in the correct sequence, preparing the clamping spring for release in advance of the actual clamping action.
2Ease of operation
If the clamping spring is arranged between the busbar and the actuating element, then the actuating element can be positioned away from the conductor connection space, but the structure becomes more complex
Solution Approach 1:
The solution resolves spatial conflicts by arranging components along different dimensional axes. The actuating element operates along one axis while the conductor connection space remains accessible along another axis, allowing both functions to coexist without interference through three-dimensional spatial arrangement.
Solution Approach 2:
The connection arrangement is segmented into distinct functional zones: the actuating element operates in one region while the conductor connection space is maintained as a separate accessible region. This segmentation allows independent optimization of each zone's functionality without compromising the other.

Function Achieved in This Case
Simplifies the handling of connecting electrical conductors by allowing flexible conductors to be easily inserted and clamped without manual actuation of the clamping spring, reducing the need for additional tools and improving user convenience.
Implementation Method 1
a clamping spring, which has a retaining leg and a clamping leg, the clamping leg being transferable into a clamping position and into a release position
Implementation Method 2
a displaceably arranged guide element, which is in operative connection with the clamping leg of the clamping spring, the clamping leg being holdable in the release position by the guide element

AI summary
A connection arrangement for connecting an electrical conductor includes: a busbar; a clamping spring, which has a retaining leg and a clamping leg, the clamping leg being transferable into a clamping position and into a release position; a conductor connection space formed between a section of the busbar and the clamping leg of the clamping spring; a displaceably arranged guide element, which is in operative connection with the clamping leg of the clamping spring, the clamping leg being holdable in the release position by the guide element; and a pivotably mounted actuating element, by which the guide element is displaceable to transfer the clamping leg of the clamping spring from the clamping position into the release position. The clamping spring is arranged between the section of the busbar and the actuating element.
