Connector Ground Member Layout for Compact Cable-to-Paddle Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector assemblies face challenges in reducing size due to non-uniform arrangement of ground paths between cables and paddle cards, leading to difficulties in minimizing overall assembly dimensions.
Innovation Solution
A connector assembly design featuring a ground member with U-shaped partitioning members arranged at a pitch twice the predetermined pitch, where the ground shields of the cables are exposed between partition walls and connected to a metal plate, forming orderly ground paths between cables and paddle cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nest parts are staggered to accommodate cables arranged at predetermined pitch, then cables can be connected to ground, but the positions where nest parts are connected to ground are not uniformly arranged, making it difficult to reduce the size of the connector assembly
Solution Approach 1:
The ground member is segmented into multiple partitioning members (first partitioning members and second partitioning members) that divide the ground shield into multiple ground contact portions. This segmentation allows uniform distribution of ground connection points along the width direction, enabling compact arrangement while maintaining reliable ground connections for all cables
Solution Approach 2:
The invention transitions from a single-layer ground connection approach to a multi-dimensional ground member structure with partitioning members extending in the width direction. This dimensional expansion allows ground shields to be connected at multiple positions simultaneously, achieving uniform ground path arrangement and reducing overall connector assembly size
2Reliability
If ground shields are connected at non-uniform positions, then cable ground paths are formed, but the connector assembly size cannot be reduced
Solution Approach 1:
Different regions of the ground shield are divided into multiple ground contact portions by the partitioning members, with each portion having optimized local characteristics. This local quality differentiation allows precise control of ground path positions, enabling uniform distribution and compact width arrangement while ensuring reliable ground connection for each cable

AI summary
A connector assembly in which ground paths between cables and a paddle card are formed and of which the size can be reduced is provided. A connector assembly includes a ground member including a plurality of partitioning members made of metal, each of which has a U-shape, and a metal plate to which the partitioning members are fixed. The ground member is configured such that the partitioning members are arranged at a pitch twice a predetermined pitch in a width direction of the connector assembly, so that partition walls of the partitioning members are arranged at the predetermined pitch in the width direction of the connector assembly. The ground shields are electrically connected to the ground member in a state where ground shields exposed from insulating films of the cables are disposed between the partition walls.
