Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductor connection terminals face challenges in achieving a compact structure and cost-effective production while efficiently utilizing installation space, as existing designs often result in electrical conductor interference due to shared connection spaces.
Innovation Solution
The introduction of a separating section on the contact leg of the clamping spring divides the connection space into spatially separate conductor connection chambers, preventing conductor interference without the need for additional partition walls, allowing for variable numbers of connectable conductors and optimizing installation space through asymmetric component arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact conductor connection terminal is designed with shared connection space, then installation space is reduced, but electrical conductor interference occurs
Solution Approach 1:
The contact leg of the clamping spring is divided into a clamping section and a separating section. The separating section extends in a direction deviating from the main extension direction of the contact leg, creating spatial separation between multiple conductor connection chambers. This segmentation allows multiple conductors to be connected in a compact terminal without interference, as each conductor has its own defined chamber while the overall terminal volume remains reduced.
2Reliability
If separate partition walls are used to divide conductor connection chambers, then conductor separation is achieved, but device complexity and production cost increase
Solution Approach 1:
The separating section is integrally formed with the contact leg of the clamping spring, merging the functions of electrical contact and chamber separation into a single component. This eliminates the need for separate partition walls or additional separating components, reducing device complexity and production cost while maintaining reliable conductor separation. The separating section serves dual purposes: electrical conduction and spatial division.
Solution Approach 2:
The contact leg is designed with multi-functionality, serving as both an electrical conductor and a chamber separator. The separating section of the contact leg performs the separation function that would traditionally require a dedicated partition wall, while the contact leg itself maintains its electrical contact function. This multi-functionality reduces the number of components and simplifies the overall structure.
3Reliability
If the separating section extends in the main direction of the contact leg, then chamber separation is achieved, but clamping effectiveness is reduced
Solution Approach 1:
The separating section extends in a direction that deviates from the main extension direction of the contact leg, creating an asymmetric structure. This asymmetric design allows the separating section to provide effective chamber separation while the clamping section maintains optimal alignment for applying clamping force to the conductor. The directional deviation enables both separation and effective clamping without interference between these functions.
