Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single-piece insulating body with integrated shielding elements is used, then electromagnetic shielding is achieved, but manufacturing complexity and cost increase significantly
Solution Approach 1:
The insulating body is divided into two separate components: a plug-in body (Steckkörper) and a connecting body (Auskopfkörper). Each component can be manufactured independently with its own shielding elements, and then assembled together. This segmentation reduces manufacturing complexity while maintaining electromagnetic shielding effectiveness through the coordinated arrangement of shielding elements in both parts.
2Strength
If screw connections are used to assemble connector parts, then mechanical strength is improved, but production time and cost increase
Solution Approach 1:
The patent replaces complex screw connections with a simplified mechanical locking system. The plug-in body and connecting body feature complementary locking elements that enable quick assembly through simple insertion and locking actions, eliminating the need for threads and union nuts while maintaining sufficient mechanical strength for the application.
3Stability of the object's composition
If a one-piece insulating body design is used, then structural integrity is maintained, but adaptability to different applications is reduced
Solution Approach 1:
By separating the insulating body into plug-in and connecting components, the patent enables independent optimization and adaptation of each part for different applications. The connecting body can be customized for various mounting configurations (angled, straight, different connection areas) while the plug-in body maintains consistent contact element arrangements, achieving both structural integrity and application versatility.
Solution Approach 2:
The modular two-part design allows the same plug-in body to be paired with different connecting bodies suited for various applications (circuit board connections, cable connections, angled or straight configurations). This universality enables a single plug-in body design to serve multiple functions across different application scenarios while maintaining structural integrity through standardized interfacing.

AI summary
The invention relates to an insulating body of a plug-in connector, said body consisting of a plug-in part (10), in which contact elements (11) are located, and of a connecting part (20) which in turn has connecting elements (21) that can be electrically connected to conductor tracks of a printed circuit board and/or to individual conductors of a multi-core cable that is to be connected. The plug-in part (10) and the connecting part (20) can be interconnected, thus allowing the contact elements (11) to make electric contact with the connecting elements (21) of the connecting part (20).
