Solution Overview
Problem
As network frequencies increase, existing shielding structures fail to effectively prevent crosstalk interference between electrical connectors on circuit boards, leading to reduced connector counts and limited shielding effectiveness.
Innovation Solution
A multi-socket panel device with a circuit board featuring through holes arranged in multiple rows, where two electrical connectors are positioned on opposite sides of the holes, causing electromagnetic waves to be reflected or refracted as they travel between different media, thereby reducing crosstalk interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shielding members are added to network cables and connectors, then shielding effect is improved, but device complexity increases
Solution Approach 1:
The patent extracts the shielding function from traditional external shielding members (grounding wires, braided nets, iron sheets) and integrates it into the circuit board structure itself through through-holes. This eliminates the need for separate shielding components while maintaining the shielding effect, thereby reducing device complexity while preserving reliability.
Solution Approach 2:
The through-holes in the circuit board act as intermediary structures that provide shielding functionality. Instead of using traditional shielding members, the patent uses the through-holes as a mediating element to achieve electromagnetic interference shielding, simplifying the overall structure by combining multiple functions into a single component.
2Reliability
If the number of electrical connectors on circuit board is reduced, then crosstalk interference is reduced, but productivity decreases
Solution Approach 1:
The patent extracts the crosstalk interference problem from the connector arrangement and addresses it by introducing through-holes as a separate shielding mechanism. This allows multiple connectors to be placed on the circuit board without increasing crosstalk, as the through-holes provide isolation between adjacent connectors, thereby maintaining productivity while ensuring reliability.
Solution Approach 2:
The patent applies local quality by positioning through-holes in specific locations between adjacent electrical connectors. This localized shielding approach provides crosstalk protection only where needed (between connectors) while allowing connectors to be densely arranged elsewhere on the circuit board, thus maintaining high productivity without compromising interference protection.
3Reliability
If slots are formed on circuit board to shield crosstalk, then crosstalk shielding is improved, but strength of circuit board structure is weakened
Solution Approach 1:
Instead of using large slots that compromise structural integrity, the patent uses thin through-holes that penetrate the circuit board. These through-holes provide shielding functionality while occupying minimal space and causing negligible weakening of the circuit board structure, thus maintaining both strength and shielding effectiveness.
Solution Approach 2:
The patent creates a porous structure in the circuit board by forming through-holes, which provides shielding functionality similar to slots but with minimal impact on structural strength. The through-holes are small and strategically positioned, allowing the circuit board to maintain its mechanical integrity while achieving the desired crosstalk shielding effect.

AI summary
A multi-socket panel device with an anti-crosstalk structure, wherein a plurality of through holes are formed on the circuit board. The through holes are arranged in two rows extending from one side of the circuit board to another side of the circuit board. Two electrical connectors disposed on the circuit board are arranged near two opposite sides of the rows of the through holes. The electromagnetic wave propagating in the circuit board are reflected or refracted by the through holes due to travel in different media, whereby the crosstalk caused by the electromagnetic wave is avoided when signals of high frequency are transmitted in two electrical connectors.
