Terminal Base Fastening Structure for Single-Handed Cable Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal base structures require manual effort to press a press block with one hand and insert a signal wire/cable with the other, making wiring and cable replacement time-consuming and labor-intensive, especially when arranging or replacing multiple wires/cables, without a two-step positioning mechanism for stable engagement.
Innovation Solution
A terminal base with a fastening structure featuring a press block that engages with a hook element, allowing cable arrangement and replacement with minimal manual labor, using a metal elastic element and a conductive terminal with a hook element and clasp portions for easy cable insertion and removal, eliminating the need for simultaneous hand operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional terminal base structure with a press block is used, then signal wire connection is achieved, but wiring requires simultaneous two-handed operation and is time-consuming
Solution Approach 1:
The press block is pre-connected to the hook element through the metal elastic element, creating a pre-assembled fastening mechanism. This preliminary configuration allows the cable to be inserted and automatically secured without requiring simultaneous manual pressing and inserting operations, significantly reducing wiring time and effort
Solution Approach 2:
The metal elastic element automatically engages the press block with the hook element when the cable is inserted. The system performs the fastening action automatically through the elastic element's inherent mechanical properties, eliminating the need for manual pressing operation and enabling single-handed cable installation
2Reliability
If a conventional press block without two-step positioning is used, then simple structure is maintained, but stable engagement of cable is not achieved
Solution Approach 1:
The engagement mechanism is divided into two distinct positioning steps: the first position where the press block initially engages the hook element, and the second position where it achieves final stable engagement. This segmentation of the engagement process into discrete steps ensures reliable cable fixation while maintaining a relatively simple overall structure
Solution Approach 2:
The press block is designed to move dynamically through two distinct positions during cable engagement. The metal elastic element provides the dynamic mechanism that allows the press block to transition from the first engagement position to the second stable engagement position, ensuring reliable cable fixation without requiring a complex rigid structure
