Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If press-fit technique is used to fix plug connector to printed circuit board, then assembly is simplified, but shielding of printed circuit board contacts becomes insufficient
Solution Approach 1:
The plug connector is divided into functionally independent components: a shield body for electromagnetic shielding, a contact carrier for electrical connections, and press-fit elements for mounting. This segmentation allows each component to optimize its specific function without compromising others.
Solution Approach 2:
The contact carrier is received within the shield body, creating a nested structure where the contact carrier is positioned inside the shielded cavity. This nesting ensures that printed circuit board contacts are surrounded by shielding material while maintaining electrical functionality.
2Object-affected harmful factors
If sufficient shielding is provided for printed circuit board contacts, then electromagnetic compatibility is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple functions are merged into the shield body: it serves as the electromagnetic shield, the mounting structure for press-fit elements, and the housing for the contact carrier. This consolidation reduces the number of separate components and simplifies manufacturing.
Solution Approach 2:
The shield body is designed as a multi-functional component that provides electromagnetic shielding, structural support for mounting, and housing for electrical contacts. This universality eliminates the need for separate dedicated components for each function.
3Object-affected harmful factors
If press-in elements and printed circuit board contacts have different plug-in directions, then shielding is improved, but assembly precision deteriorates
Solution Approach 1:
The contact carrier is designed with asymmetric contact orientations (e.g., right-angle or L-shaped contacts) that allow electrical contacts to be perpendicular to the plug-in direction. This asymmetric design maintains shielding effectiveness while enabling precise alignment during assembly.

AI summary
The disclosure relates to a plug connector for direct electrical contact with a printed circuit board comprising at least one printed circuit board contact to be shielded, one shield body for shielding the at least one printed circuit board contact, and one contact carrier which is received in the shield body and has the at least one printed circuit board contact to be shielded. At least two press-in elements for pressing into the printed circuit board are arranged on a connection surface of the shield body facing toward the printed circuit board, and a mounting hole for mounting the contact carrier in the shield body is closed by means of a shield plate. At least one printed circuit board contact and the press-in elements have a common and/or identical plug-in direction. The disclosure also relates to a method for manufacturing the plug connector.
