Printed Filter Bracket for Plug Connector Shield Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connectors struggle to effectively filter out interference induced by the shielding layer of cables, leading to additional electromagnetic interference, and require complex additional circuit devices that complicate ground design and are difficult to integrate within limited plug connector spaces.
Innovation Solution
A bracket with a printed filter circuit, comprising at least one resistor and capacitor connected in parallel, is integrated into the plug connector. This filter circuit is electrically connected to the shielding layer of the cable and grounded, allowing it to filter out induced currents in the ground loop, thereby reducing interference.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate electromagnetic interference filter circuit is provided on the electronic device, then interference filtering capability is improved, but device complexity and ground design difficulty increase
Solution Approach 1:
The filter circuit is merged with the bracket structure, combining the mechanical support function with the electrical filtering function. The bracket serves dual purposes: providing structural support and housing the filter circuit components (resistors and capacitors) that filter electromagnetic interference, thereby eliminating the need for separate filter circuits.
Solution Approach 2:
The bracket is transformed into a multi-functional component that simultaneously performs mechanical support and electrical interference filtering. By integrating the filter circuit into the bracket, the same structural element serves multiple functions: mechanical stabilization, electrical connection, and electromagnetic interference filtration.
2Object-affected harmful factors
If additional circuit equipment is added to the cable system, then interference filtering is improved, but ease of manufacture and integration difficulty worsen
Solution Approach 1:
The filter circuit components (resistors and capacitors) are integrated directly into the bracket structure, combining multiple functions into a single manufactured component. This merger simplifies the manufacturing process by reducing the number of separate parts that need to be produced and assembled, while still providing effective interference filtering.
3Object-affected harmful factors
If the bracket is transformed into a mechatronic device with printed filter circuit, then interference filtering capability is improved, but manufacturing complexity increases
Solution Approach 1:
Traditional mechanical brackets are replaced with mechatronic brackets that incorporate printed electronic circuits. The filter circuit is printed directly onto the bracket structure, replacing what would traditionally be separate mechanical and electrical components, thereby integrating filtering capability into the mechanical support structure.
Solution Approach 2:
The bracket undergoes a parameter change from purely mechanical to mechatronic by incorporating printed electronic circuits. This parameter change enables the bracket to perform both mechanical support and electrical filtering functions, with the printed circuit parameters (resistors and capacitors) providing the filtering capability.
