Terminal Block Pivoting Pressing Element for Compact Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal block structures occupy considerable operating space due to the placement of the pressing element assembly, which limits their compactness and installation efficiency.
Innovation Solution
A terminal block structure with an insulative base, conductive terminal, pivoting pressing element, and clamping elastic piece, where the pressing element includes a pivoting portion, arm, and handle, allowing for compact design and reduced operational space by positioning the handle beside the wire insertion hole, enabling effective space-saving through the use of a pivoting mechanism and elastic clamping action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressing element assembly is formed at a side position of the insulative base, then the wire insertion function is achieved, but the operating space is occupied considerably
Solution Approach 1:
The pressing element is repositioned from a side-mounted configuration to a top-mounted configuration on the insulative base. The pressing element is disposed on the insulative base at a position overlapping with the wire insertion hole when viewed in plan view, allowing the pressing action to occur from above rather than from the side, thereby reducing the lateral operating space required.
Solution Approach 2:
The pressing element is integrated directly onto the insulative base structure, merging the pressing function with the base itself. This integration eliminates the need for separate side-mounted pressing assemblies and reduces the overall footprint of the terminal block structure.
2Area of stationary object
If the pressing element is positioned to overlap the wire insertion hole, then the operating space is reduced, but the structural complexity increases
Solution Approach 1:
The insulative base serves multiple functions: it provides mechanical support, electrical insulation, and houses the pressing element integration. The top surface of the insulative base is designed to receive and support the pressing element, while also guiding wire insertion, thereby reducing structural complexity through multi-functionality.
Solution Approach 2:
The pressing element includes a pressing portion with a pressing surface that provides flexible contact with the wire. The elastic pressing portion can deform to accommodate wires of different sizes and shapes, providing a simple yet effective pressing mechanism without requiring complex adjustable structures.

Function Achieved in This Case
The compact design allows for more terminal blocks to be installed in the same volume, reducing installation costs and improving operational efficiency by minimizing the space required for handling.
Implementation Method 1
The clamping elastic piece is disposed in the chamber. An end of the clamping elastic piece is operatively moved to inside or outside of the wire insertion hole through the pressing portion.
