Type-C Connector Terminal Assembly for Arc Height Coplanarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing type-C connectors face challenges in maintaining the coplanarity degree of arc height of terminals, which are difficult to control due to their inner placement, necessitating additional shaping processes for metallic sheets.
Innovation Solution
The electrical connector design includes an inner housing with stacked insulators and metallic sheets that apply pressure on terminals during assembly, ensuring good coplanarity of arc height and reducing production complexity by symmetrically arranging components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If terminals are disposed on the inner side of the connector housing, then the connector structure is compact, but the coplanarity degree of arc height of the terminals becomes unstable and true position control becomes difficult
Solution Approach 1:
The patent applies preliminary action by pre-forming the metallic sheet with predetermined curvature and positioning features before assembly. The metallic sheet is pre-shaped to have the correct arc height and coplanarity, and includes positioning protrusions that engage with corresponding grooves in the housing, ensuring accurate terminal positioning without requiring complex post-assembly adjustments or second shaping operations.
2Volume of moving object
If terminals are disposed on the inner side of the connector housing, then the connector structure is compact, but additional second shaping processing is required for the metallic sheet
Solution Approach 1:
The metallic sheet is pre-formed with the correct curvature, arc height, and positioning features in a single shaping operation before assembly. This preliminary action eliminates the need for a second shaping processing step, as the metallic sheet arrives at assembly already configured to achieve the desired terminal coplanarity and positioning when installed in the housing.
3Manufacturing precision
If metallic sheets undergo second shaping processing, then terminal positioning accuracy can be improved, but production time and manufacturing complexity increase
Solution Approach 1:
The metallic sheet is pre-shaped with the correct terminal positioning geometry, arc height, and coplanarity features in a single forming operation. The pre-formed metallic sheet includes integrated positioning protrusions that automatically align with housing grooves during assembly, achieving high terminal positioning accuracy without requiring a second shaping process, thereby maintaining high production efficiency and yield.
