Terminal Block Structure With Elastic Prestress And Stoppers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal blocks face inconvenience and increased working time due to the dislocation of the upper terminal base relative to the body and lower terminal base when loosening the screw component, requiring re-alignment for reconnection.
Innovation Solution
The improved terminal block structure incorporates a body with a vertically configured opening slot, a lower terminal base with a pin and stopper, an upper terminal base with a screw component and another stopper, and an elastic component that provides prestress to prevent dislocation by engaging the stoppers, allowing for easier retraction and reconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screw component is loosened to retract the terminal, then the terminal can be removed, but the upper terminal base becomes dislocated relative to the body and lower terminal base
Solution Approach 1:
The patent applies preliminary anti-action by designing stoppers that prevent dislocation before it can occur. When the screw component is loosened, the stoppers on the upper terminal base engage with corresponding features on the body, preemptively counteracting any potential dislocation and maintaining proper alignment throughout the retraction process.
Solution Approach 2:
The patent implements preliminary action by pre-positioning the stoppers on the upper terminal base in alignment with the body features before any loosening occurs. This preliminary configuration ensures that as soon as the screw is loosened, the stoppers are already in place to guide and constrain the upper terminal base, preventing dislocation from the outset.
2Ease of operation
If the upper terminal base is dislocated, then the terminal can be accessed, but reconnection requires time-consuming re-alignment
Solution Approach 1:
The stoppers provide preliminary anti-action by preventing dislocation that would otherwise require re-alignment. During terminal access, the stoppers maintain the upper terminal base in its correct position relative to the body, ensuring that when reconnection is needed, no time-consuming re-alignment is required.
Solution Approach 2:
The patent applies self-service through the stopper mechanism that automatically maintains alignment without user intervention. The stoppers continuously constrain the upper terminal base position throughout the terminal access and reconnection cycle, making the system self-aligning and eliminating the need for manual re-alignment operations.
3Device complexity
If conventional terminal block design is used, then结构简单 (structure is simple), but the upper terminal base dislocates when loosening
Solution Approach 1:
The patent applies segmentation by dividing the upper terminal base into functional components: the main body and separate stoppers. This segmentation allows the stoppers to independently perform the alignment function while the main body handles terminal connection, resolving the dislocation issue with minimal addition to overall structural complexity.
Solution Approach 2:
The stoppers act as intermediary elements between the upper terminal base and the body. These intermediaries transfer and constrain the positional relationship, ensuring stable alignment without requiring fundamental changes to the overall terminal block structure.
