Terminal Base Fastening Structure for One-Handed Cable Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal base structures require manual effort and time for wiring and cable replacement, as maintenance staff need to press a press block with one hand and insert cables with the other, lacking labor-saving assistance for efficient arrangement or replacement.
Innovation Solution
A terminal base with a fastening structure featuring a body, conductive terminal, metal elastic element, and press block, allowing for quick and convenient cable arrangement or replacement using a hook element and press block that engages with a metal elastic element to secure cables with minimal manual labor, enabling one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional terminal base structure is used, then the wiring can be completed, but the maintenance staff needs to press the press block with one hand and insert cables with the other, which is time-consuming and labor-intensive
Solution Approach 1:
The metal elastic element automatically returns to its original state after being pressed, causing the press block to automatically return to its initial position. This self-service mechanism eliminates the need for manual operation to reset the press block, allowing maintenance staff to quickly insert multiple cables without time-consuming manual adjustments.
Solution Approach 2:
The press block is designed to be movable rather than fixed, allowing it to be pressed during cable insertion and automatically return to its initial position. This dynamic design enables the wiring process to be completed in one continuous motion without pausing to manually reset components, significantly reducing wiring time and improving operational efficiency.
2Productivity
If a conventional terminal base structure is used, then the cable can be connected, but the wiring process requires simultaneous two-hand operation which reduces productivity
Solution Approach 1:
The metal elastic element provides automatic reset functionality, making the press block self-servicing. After the maintenance staff releases the press block, it automatically returns to its initial position without requiring manual intervention, enabling continuous one-handed operation and improving wiring efficiency.
Solution Approach 2:
The press block is pre-positioned in an initial state where it can be easily pressed and will automatically return. This preliminary arrangement of the press block and metal elastic element allows the maintenance staff to perform cable insertion operations sequentially with one hand, eliminating the need for simultaneous two-hand operation and increasing productivity.

Function Achieved in This Case
The solution significantly reduces the time and labor required for wiring and cable replacement, allowing for efficient and flexible insertion and removal of cables, enhancing maintenance efficiency by eliminating the need for simultaneous hand operation of the press block and cable insertion.
Implementation Method 1
The metal elastic element includes a contact end and a movable end. The contact end is in contact with the conductive terminal. The movable end is elastically disposed inside the accommodating space.
