Electrical Power Connector Stepped Stop Portions and Partition Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical power connectors face challenges in maintaining structural stability and efficient heat dissipation, leading to potential damage from excessive compression and reduced retaining force, which affects power transmission quality and system safety.
Innovation Solution
The electrical power connector features an electrically insulative housing with mating portions, partition plates, accommodation chambers, and springy hooks that secure conducting terminals, ensuring stable positioning and efficient heat dissipation through strategically designed stop portions and guide grooves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the electrically insulative plastic housing is excessively compressed to secure the power conducting metal terminals, then the retaining force is initially improved, but the housing may be damaged or develop a ridged surface, causing the retaining force to decrease and the barbed portions to be forced out of place
Solution Approach 1:
The patent introduces partition plates as intermediary components between the housing and the barbed portions of the terminals. These partition plates provide a dedicated positioning surface that distributes compression forces evenly, preventing direct excessive compression of the housing while maintaining secure retention of the terminals. The partition plates act as mediators that resolve the conflict between needing strong retention and avoiding housing damage.
2Stability of the object's composition
If the housing is compressed to improve terminal positioning, then initial positioning stability is improved, but the housing may be damaged causing reduced retaining force and potential displacement when compressed again
Solution Approach 1:
The patent divides the housing interior into separate compartments using partition plates. This segmentation creates dedicated accommodation chambers for each terminal, providing stable positioning surfaces that prevent terminal displacement without requiring excessive compression of the housing structure. The partition plates bear the positioning function, preserving housing structural integrity.
3Ease of manufacture
If conventional barbed portions are used for terminal positioning, then assembly is simplified, but the retaining force is reduced when the housing is compressed, causing terminals to be forced out of place
Solution Approach 1:
The partition plates serve as intermediary structures that work in conjunction with the barbed portions to enhance terminal retention. The barbed portions provide initial mechanical engagement, while the partition plates provide stable positioning surfaces that maintain retention force even when the housing is compressed, preventing terminal displacement.
Solution Approach 2:
The partition plates are pre-installed in the housing to create predetermined positioning surfaces and accommodation chambers before terminals are inserted. This preliminary action ensures that terminals will be properly positioned and retained without requiring excessive housing compression during assembly, maintaining both ease of assembly and reliable retention.
