Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connecting portion is bent and extended along the vertical direction with multiple bending angles to connect the contact portion and conductive portion, then the connecting portion can be facilitated to bend and extend, but the bending angles increase signal transmission loss and resistance, affecting high frequency characteristics
Solution Approach 1:
The connecting portion is designed as an arc-shaped structure that smoothly curves between the contact portion and conductive portion, eliminating sharp bending angles. This curved configuration reduces signal transmission loss and resistance while maintaining the ability to connect the contact portion and conductive portion effectively.
2Device complexity
If the two differential signal terminals are arranged adjacent in the vertical direction with identical arranging direction and bending direction, then the structure is simplified, but the lengths of the differential signal terminals become different, affecting the coupling between terminals
Solution Approach 1:
The connecting portions of the two differential signal terminals are designed with different arc-shaped configurations. By making the arranging direction and bending direction different for the two terminals, the patent achieves equal lengths for both terminals, improving coupling and high frequency characteristics while maintaining structural simplicity.
3Stability of the object's composition
If the insulating block is arc-shaped with electrical modules stacked along the vertical direction, then position limiting is improved without easy displacement, but the structure complexity increases
Solution Approach 1:
The insulating block is designed with an arc-shaped structure that provides natural position limiting for the electrical modules stacked along the vertical direction. This curved configuration prevents easy displacement of modules while maintaining a relatively simple overall structure, as the arc shape inherently provides mechanical constraint.

AI summary
An electrical connector includes multiple electrical modules sequentially stacked along a vertical direction. Each electrical module includes an insulating block being arc-shaped, a row of conductors fixed to the insulating block, and a first shielding member. The row of conductors includes multiple first grounding conductors and multiple pairs of first signal conductors arranged on the insulating block along a left-right direction. The two first signal conductors in a same pair of first signal conductors have a same length. The first shielding member has a first main body portion overlapping with a projection of one pair of first signal conductors in the vertical direction. The first shielding member and each conductor bend and extend downward from a top thereof and backward from a front thereof to be arc-shaped. The first contact portions of the row of conductors located on the same electrical module are located on a same horizontal plane.
