Terminal Block Pressing Structure for Stable Wire Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal blocks with spring pieces often suffer from insufficient elastic pressing force, leading to poor contact or loosening between wires and terminals.
Innovation Solution
A terminal block design that includes a housing structure, a handle, a spring piece with a pressed segment, and an elastic element, where the elastic element enhances the pressing force on the spring piece's pressed segment, ensuring a stable connection even with insufficient clamping force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only a spring piece is used for clamping the wire, then the device structure remains simple, but the clamping force becomes insufficient leading to poor contact or loosening
Solution Approach 1:
The elastic element is nested within the housing structure and works in conjunction with the spring piece. The elastic element's pressing segment is positioned to press against the pressed segment of the spring piece, creating a nested arrangement where one component (elastic element) is housed within or alongside another component (spring piece) to enhance functionality without significantly increasing external complexity
Solution Approach 2:
The elastic element acts as an intermediary component between the housing structure and the spring piece. By pressing the pressed segment of the spring piece, the elastic element mediates the force transmission to ensure adequate clamping force on the wire, preventing poor contact or loosening while maintaining structural simplicity
2Force
If the spring piece elastic pressing force is increased to improve clamping, then contact stability improves, but the device complexity increases due to additional components
Solution Approach 1:
The elastic element and spring piece are combined to work together as an integrated clamping system. The elastic element's pressing segment presses against the spring piece's pressed segment, merging their force-generating capabilities to achieve adequate clamping force without requiring a completely separate or more complex clamping mechanism
Solution Approach 2:
The elastic element is positioned within the housing structure in close proximity to the spring piece, creating a nested arrangement where the elastic element supports and enhances the spring piece's clamping action. This nested configuration allows both components to contribute to force generation while minimizing the overall space and complexity required
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
The enhanced terminal block design guarantees a stable electric connection between the wire and the terminal, preventing poor contact or loosening, even when the initial clamping force is insufficient.
Implementation Method 1
The elastic element is disposed in the shell and has a second fixed segment and a pressing segment. The second fixed segment is fixed in the housing structure. The pressing segment is disposed in the swing path and capable of elastically moving relative to the second fixed segment.
