Engineering Contradiction Analysis
1Reliability
If traditional mating structures are used for plug and receptacle connectors, then reliable electrical connections can be achieved, but the structure becomes complex and alignment becomes difficult
Solution Approach 1:
The patent employs asymmetric design by creating an oblique mating interface between the plug and receptacle connectors. The plug connector has a sloped mating surface that corresponds to a complementary sloped receiving surface in the receptacle connector, forming an asymmetric oblique engagement geometry. This asymmetric oblique interface simplifies the mating structure by providing self-alignment during insertion while maintaining reliable electrical connections through the angled contact surfaces.
2Reliability
If traditional mating structures are used for plug and receptacle connectors, then electrical connections can be established, but alignment precision deteriorates
Solution Approach 1:
The asymmetric oblique mating interface provides built-in alignment guidance. The sloped surfaces of the plug and receptacle connectors are designed to mate at a specific angle, which automatically guides the plug into proper alignment during insertion. This geometric constraint ensures precise alignment without requiring complex alignment features or high-precision manufacturing tolerances on multiple surfaces.
3Stability of the object's composition
If oblique mating interface is used, then alignment and stability are enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent merges the alignment function and the electrical contact function into a single oblique mating interface. The sloped surfaces serve dual purposes: providing mechanical alignment guidance and establishing electrical contacts simultaneously. This integration reduces the need for separate alignment features and simplifies the manufacturing process compared to traditional designs that require multiple precisely positioned features.

AI summary
An angled type connector assembly includes a receptacle connector mounted upon a printed circuit board and having an insulative housing with an oblique opening to receive a plug connector, and a bottom opening through which the mating pads on the printed circuit board is upwardly exposed. The plug connector includes two rows of contacts respectively mechanically and electrically connected to the corresponding two rows of wires. The plug connector forms an oblique mating end or interface relative to an extending direction of the plug, on which the contacting sections of the contacts are exposed to mate with the corresponding mating pads on the printed circuit board.
