Plug-In EMC Filter Housing for Replaceable Interference Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing EMC filters integrated with electronic components require replacement or adjustment together, leading to inefficient resource use and unnecessary replacement of intact components when decoupling is needed.
Innovation Solution
An EMC filter plug-in arrangement with a plug-in housing and receptacle allows for separate replacement and modification of EMC filters by using flexible electrical conductor contacts and a plug-in mechanism, enabling decoupling and coupling without affecting the electronic component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the EMC filter is permanently integrated into the electronic component on a common circuit board, then the electrical path for interference dissipation is minimized, but the filter cannot be replaced or adjusted separately when needed
Solution Approach 1:
The invention divides the integrated EMC filter and electronic component into two separate but connectable parts: a plug-in housing containing the EMC filter and a receptacle on the electronic component. This segmentation allows the filter to be replaced independently while maintaining the electrical connection for interference dissipation.
Solution Approach 2:
The plug-in housing acts as an intermediary component that bridges the EMC filter and the electronic component. It provides electrical conductor contacts that establish electrical connection when plugged into the receptacle, enabling the filter to be electrically connected without permanent integration.
2Device complexity
If the EMC filter is permanently integrated into the electronic component, then assembly is simplified, but the entire electronic component must be replaced when the filter is faulty or needs adjustment
Solution Approach 1:
By segmenting the EMC filter into a separate plug-in module, the invention enables independent replacement of the filter without replacing the entire electronic component. The plug-in housing with receptacle allows the filter to be exchanged while the main electronic component remains intact.
Solution Approach 2:
The EMC filter is extracted from the permanent integration into the electronic component and placed in a separate plug-in housing. This extraction allows the filter to be removed and replaced independently, improving ease of repair and maintenance while maintaining the electrical connection through the plug-in mechanism.
3Ease of manufacture
If the EMC filter is permanently integrated, then resource utilization is maximized through permanent installation, but flexibility for selective adaptation is lost
Solution Approach 1:
The invention introduces dynamic replaceability to the EMC filter installation. The plug-in housing allows the filter to be dynamically inserted and removed from the electronic component, providing flexibility for selective adaptation while maintaining ease of manufacture through standardized plug-in connections.
Solution Approach 2:
The plug-in housing with standardized electrical conductor contacts and receptacle connection creates a universal interface that can accommodate different EMC filter configurations. This universality enables selective adaptation of filters to match different electronic component requirements without redesigning the entire system.

AI summary
An EMC filter plug-in arrangement with an EMC filter to avoid or reduce electrical and/or electromagnetic interference caused by an electronic component, in particular an inverter of a refrigerant compressor. The EMC filter plug-in arrangement has an EMC filter, a plug-in housing formed for receiving the EMC filter and having electrical conductor contacts formed on the outside which are in electrical contact with the EMC filter, and a plug-in receptacle formed for arrangement with an electronic component into which the plug-in housing can be plugged in to provide electrical contact between the EMC filter and the electronic component.
