Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If terminal density is increased and miniaturization is pursued, then connector size is reduced, but terminal arrangement difficulty increases
Solution Approach 1:
The connector is divided into multiple layers, with cable connection portions arranged on different layers and elastic mating portions arranged on the same layer. This segmentation allows terminals to be organized systematically, reducing arrangement difficulty while maintaining high density and miniaturization.
2Adaptability or versatility
If cable connection portions are arranged on different layers, then cable management becomes complex, but terminal connection flexibility improves
Solution Approach 1:
Cable connection portions are arranged in the vertical dimension across multiple layers, while elastic mating portions are arranged on the same horizontal layer. This dimensional separation allows cables to connect at different heights while maintaining simple planar arrangement of mating portions, improving flexibility without increasing management complexity.
3Reliability
If elastic mating portions protrude beyond the insulating body surface, then contact with circuit board pads is improved, but connector height increases
Solution Approach 1:
The elastic mating portions are designed with elastic properties, allowing them to protrude beyond the insulating body surface to ensure reliable contact with circuit board pads. The elasticity enables automatic adjustment and maintenance of contact pressure, improving reliability while minimizing the required protrusion distance and thus controlling connector height.

AI summary
A wire-to-board connector includes an insulating body, a number of first conductive terminals, a number of second conductive terminals, a number of first cables and a number of second cables. The first conductive terminals are arranged at intervals along a first direction. The first conductive terminal includes a first elastic mating portion and a first cable connection portion. The second conductive terminal includes a second elastic mating portion and a second cable connection portion. The first cable connection portion and the second cable connection portion are arranged in a misalignment manner along a second direction perpendicular to the first direction. The first elastic mating portion and the second elastic mating portion protrude beyond a first surface of the insulating body so as to abut against metal conductive pads of a circuit board. Besides, a wire-to-board connector assembly having the wire-to-board connector is also disclosed.
