Conductor Terminal Mounting Wall Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conductor connection terminals with clamping springs and busbar pieces lack stability and stiffness, leading to ineffective clamping and opening of electrical conductors.
Innovation Solution
The busbar piece features a contact wall that supports the vertical section of the contact leg, forming a self-supporting system with the clamping spring, where the vertical section is aligned perpendicularly to the main direction of the busbar piece, and a transverse web engages under the busbar piece, providing stability and stiffness by distributing forces between the clamping leg and the busbar piece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the clamping spring is mounted on the busbar section without additional support structures, then the device complexity is reduced, but the stability and stiffness of the clamping mechanism deteriorates
Solution Approach 1:
The busbar section is segmented into functional zones: a mounting region with a mounting wall for supporting the clamping spring, and a clamping region with clamping sections. This segmentation allows the mounting wall to provide stable support while keeping the overall structure integrated and simple.
Solution Approach 2:
The clamping spring is nested within the recess of the mounting wall, which provides support from multiple sides. The mounting wall surrounds and supports the clamping spring, creating a stable configuration without requiring external support structures.
2Strength
If the clamping spring is designed with extended support structures, then the stiffness and stability improve, but the device complexity increases
Solution Approach 1:
The mounting wall is merged with the busbar section to form an integrated structure. The mounting wall is formed as an integral part of the busbar section, combining the support function with the existing busbar structure, thereby increasing stiffness without adding separate support components.
Solution Approach 2:
The mounting wall serves multiple functions: it provides support for the clamping spring, defines the recess for positioning, and integrates with the busbar section structure. This multi-functionality increases stiffness while avoiding additional dedicated support structures.
3Device complexity
If the clamping spring is supported only at one point, then the structure remains simple, but the clamping spring tilts and loses stability during operation
Solution Approach 1:
The clamping spring is nested within the recess of the mounting wall, which provides support from multiple sides including the back and sides. This nested configuration prevents tilting by distributing support forces across multiple contact points while maintaining structural simplicity.
Solution Approach 2:
The mounting wall acts as an intermediary structure between the busbar section and the clamping spring. It provides a stable mounting surface and recess that positions the clamping spring correctly, preventing tilting without requiring complex external support mechanisms.
4Stability of the object's composition
If additional support structures are added to stabilize the clamping spring, then the stability improves, but the manufacturing complexity increases
Solution Approach 1:
The mounting wall is merged with the busbar section to form an integral structure that can be manufactured as a single piece. This integration provides stable support for the clamping spring while maintaining manufacturing simplicity, as no separate support components need to be assembled.
Solution Approach 2:
The busbar section is segmented to include a mounting wall with a recess, creating a built-in support structure. This segmentation allows the support function to be integrated into the manufacturing process of the busbar section itself, avoiding the need for separate support components and assembly steps.

Function Achieved in This Case
This configuration ensures a stable and stiff clamping mechanism that effectively absorbs forces during conductor clamping and opening, preventing tilting of the clamping spring and maintaining a secure connection.

AI summary
A conductor terminal (29) with a busbar section (2) and a clamping spring (3) is described. The clamping spring (3) has a clamping leg (13) oriented towards the busbar section (2) to form a clamping point for connecting an electrical conductor (36) between the clamping leg (13) and the busbar section (2), a spring arc (12) adjoining the clamping leg (13), and a contact leg (9) extending with a vertical section (10) transversely to the busbar section (2). The vertical section (10) of the contact leg (9) has a recess (19) with edges that encompass the busbar section (2).The busbar section (2) has a mounting wall (28) which is arranged adjacent to the wall surface of the vertical section (10) of the mounting leg (9) extending transversely to the busbar section (2) and which is located on the side of the vertical section (10) facing away from the clamping leg (13), and is designed to support the vertical section (10) of the mounting leg (9) with this wall surface facing away from the clamping leg (13) on the mounting wall (28).
