Terminal Block Toggle Member for Wire Insertion Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited moving range of the stem member in existing terminal block structures makes it difficult to insert wires due to restricted opening of the elastic sheet, which affects space efficiency and ease of use.
Innovation Solution
A terminal block structure with an insulative base, conductive terminal, toggle member, and elastic clamping piece, where the toggle member includes a pivoting portion and a pressing portion that allows the elastic clamping piece to open and close maximally, increasing the wire insertion ease and reducing operational space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the moving range of the stem member is limited to within two sides of the insulative base, then the space efficiency is improved, but the opening extent of the elastic sheet is reduced making wire insertion difficult
Solution Approach 1:
The stem member is designed to move dynamically between two states: during wire insertion it extends beyond the insulative base to provide sufficient opening force, and during normal operation it retracts to within the base boundaries to save space. This dynamic positioning resolves the contradiction between space efficiency and ease of operation.
Solution Approach 2:
Before wire insertion, the stem member is preliminarily positioned to engage the elastic sheet and create sufficient opening extent. This preliminary action ensures that when the wire needs to be inserted, the elastic sheet is already in an optimal state for easy insertion, thus solving the contradiction without requiring permanent extension of the stem member.
2Ease of operation
If the stem member extends beyond the insulative base to increase opening extent, then wire insertion ease is improved, but the operation space increases reducing space efficiency
Solution Approach 1:
The stem member transitions from a static extended position to a dynamic retracted position after wire insertion. This allows the system to enjoy the benefits of extended reach during insertion while minimizing space occupation during normal operation, effectively resolving the contradiction between ease of operation and space efficiency.
Solution Approach 2:
The extended position of the stem member is discarded after wire insertion is complete, and the stem member recovers to its compact position within the insulative base. This temporary extension only when needed resolves the contradiction by providing extended capability without permanent space occupation.

Function Achieved in This Case
This design enhances wire insertion ease and space efficiency by allowing a greater opening extent of the elastic clamping piece, enabling easier wire insertion and accommodating more terminal blocks in the same volume, thereby reducing installation and use costs.
Implementation Method 1
An end of the elastic clamping piece is pressed by the pressing portion to operably open or close the wire hole
Implementation Method 2

AI summary
A terminal block structure includes an insulative base, a conductive terminal, a toggle member and an elastic clamping piece. The insulative base has a chamber, a wire hole and an opened trough communicating with the chamber. The wire hole and the opened trough are located on the same side of the insulative base. The conductive terminal is fixed in the chamber. The toggle member has a main body, a stem and a pressing portion extended from the main body. The main body has a pivoting portion pivotally connected to the insulative base. The stem projects to outside of the insulative base from the opened trough and is movable on a lateral side of the wire hole. The elastic clamping piece is disposed in the chamber. An end of the elastic clamping piece is pressed by the pressing portion to operably open or close the wire hole.
