Connector Zigzag Contact Shielding Crosstalk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-plug connectors face challenges in minimizing crosstalk between contact element pairs, leading to signal disruption during radio frequency signal transmission, while existing designs with comprehensive shielding increase production costs.
Innovation Solution
The connector features a zigzag arrangement of contact element pairs with a simple shielding element placed between rows, maximizing distance between pairs and using a single, geometrically simple shielding element to reduce crosstalk effectively.

1Object-affected harmful factors
If comprehensive shielding is integrated into the housing surrounding each contact element pair, then crosstalk between contact elements is reduced, but production costs increase
Solution Approach 1:
The shielding is segmented into individual shielding elements (34) that are placed only between specific contact element pairs, rather than providing continuous comprehensive shielding around each pair. This selective segmentation reduces the total amount of shielding material and assembly complexity while maintaining effective crosstalk reduction where most needed.
Solution Approach 2:
Shielding is applied locally only between adjacent contact element pairs in rows, rather than uniformly around all contact elements. The shielding elements (34) are positioned specifically in the gaps between contact pairs where crosstalk occurs, providing targeted protection without the cost and complexity of complete surrounding shielding for each contact element.
2Area of stationary object
If contact element pairs are arranged closer together to maximize space utilization, then installation space is reduced, but crosstalk between pairs increases
Solution Approach 1:
Shielding elements (34) are introduced as intermediary components between contact element pairs, allowing the pairs to be positioned closer together while maintaining electrical isolation. These shielding elements act as mediators that enable compact arrangement without direct electromagnetic interference between adjacent contact pairs.
Solution Approach 2:
The shielding elements extend in the plugging direction (perpendicular to the contact pair arrangement plane), creating a three-dimensional shielding structure. This vertical dimension provides effective electromagnetic isolation while allowing horizontal spacing between contact pairs to be minimized for compact installation.
