Jointless Shielded Connector Assembly for Compact Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies face challenges in size reduction while maintaining a shield function due to clearance between the shell and housing, which increases the overall size of the connector and assembly.
Innovation Solution
The connector assembly features a jointless peripheral wall structure around the terminals and shell, integrated with the housing through insert molding, allowing for a smaller form factor and enhanced shield function by eliminating gaps between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shell is attached to the housing by press-fitting, then the shield function is provided, but a clearance is formed between the shell and housing, increasing the size of the connector assembly
Solution Approach 1:
The patent merges the shell and housing into a single integrated component formed by press-fitting the shell onto the housing. This integration eliminates the clearance between separate components while maintaining the shield function, thereby reducing the overall size of the connector assembly.
Solution Approach 2:
The shell is nested onto the housing in a press-fitted manner, where the shell forms an outer protective layer around the housing and terminals. This nested structure allows the shield function to be provided without requiring additional space, as the shell and housing occupy the same spatial envelope.
2Volume of moving object
If the shell and housing are integrated through press-fitting, then the size is reduced, but the manufacturing complexity increases
Solution Approach 1:
The shell is prepared in advance with a press-fitted structure that includes protrusions matching recesses in the housing. This preliminary preparation of the press-fitting features before final assembly simplifies the manufacturing process by pre-defining the integration points, reducing the complexity of the actual assembly operation.
