Partitioned Connector Structure for Compact High-Frequency Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector devices fail to effectively suppress noise interference between different types of signals in a compact design, as they lack efficient isolation mechanisms for high-frequency signals and other noise-prone contacts.
Innovation Solution
The connector device employs a partitioned contact holding portion with distinct areas for different types of contacts, where high-frequency and noise-sensitive contacts are isolated in separate second type holding areas, and noise suppression is enhanced by conductive partition walls and surrounding walls electrically connected to ground, along with intra- and inter-area connecting plates.

1Volume of moving object
If connector devices use compact design without partition walls, then the connector size is reduced, but noise interference between different types of signals increases
Solution Approach 1:
The contact holding portion is segmented into multiple distinct areas (first type holding area for low-frequency signals, second type holding area for high-frequency signals) using conductive partition walls. This segmentation isolates noise-sensitive high-frequency contacts from noise-generating low-frequency contacts, effectively suppressing electromagnetic interference while maintaining a compact overall connector structure.
Solution Approach 2:
Different regions of the connector are assigned different functional qualities: the first type holding area accommodates contacts for low-frequency signals, while the second type holding area accommodates contacts for high-frequency signals. The partition walls are strategically positioned to provide localized shielding where needed, optimizing noise suppression without requiring the entire connector to be enlarged.
2Object-affected harmful factors
If partition walls are added to isolate high-frequency contacts, then noise suppression is improved, but device complexity increases
Solution Approach 1:
The conductive partition walls serve multiple functions simultaneously: they act as structural dividers to separate different contact types, provide electromagnetic shielding to suppress noise interference, and are electrically connected to ground conductors to establish reference potential. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The partition walls are integrated with the ground conductor system, merging the shielding function with the grounding function. The surrounding walls are also combined with ground connections, creating a unified structure that provides both mechanical support and electromagnetic shielding, thus reducing overall structural complexity.
3Object-affected harmful factors
If surrounding walls are added around individual contact areas, then noise suppression is enhanced, but manufacturing complexity increases
Solution Approach 1:
The partition walls and surrounding walls are combined into a single integrated conductive structure that is molded as one piece with the insulating housing. This integration eliminates the need for separate assembly steps for installing partition walls and surrounding walls, significantly simplifying the manufacturing process while maintaining effective noise suppression through the continuous conductive shielding.
Solution Approach 2:
The connector utilizes composite construction with an insulating housing material (such as molded resin) integrated with conductive materials (metal partition walls and surrounding walls). This composite approach allows the insulating and conductive components to be formed together in a single manufacturing process, reducing the number of manufacturing steps while achieving both electrical insulation and electromagnetic shielding functions.
