Conical Sealing Arrangement for Compressor Electrical Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing arrangements for electrically driven compressors in climate control systems of motor vehicles are complex, prone to malfunctions, and require multiple components to ensure hermetic sealing and insulation, increasing the risk of defects and assembly time.
Innovation Solution
A sealing arrangement featuring a conical passage aperture with a hollow truncated cone sealing element that fully encompasses the connecting element, providing three sealing faces for hermetic and electrical insulation, reducing the number of components and simplifying assembly by integrating the sealing element with the support member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sealing arrangements with multiple components are used, then hermetic sealing and insulation are ensured, but device complexity and assembly time increase
Solution Approach 1:
The patent combines multiple sealing functions into a single integrated sealing element. This element simultaneously provides hermetic sealing against refrigerant/oil infiltration and electrical insulation between conductive components, replacing what would traditionally require multiple separate sealing components and insulation elements.
Solution Approach 2:
The sealing element is designed as a multi-functional component that performs multiple sealing tasks at different interfaces. It seals the passage aperture against the housing, seals around the connecting element, and provides electrical insulation, thereby serving universal sealing and insulation purposes throughout the system.
2Reliability
If multiple sealing components are used, then insulation resistance is maintained, but assembly time and production costs increase
Solution Approach 1:
The patent merges insulation functionality directly into the sealing element structure. The sealing element is designed with electrically insulating material or structure that provides insulation resistance between conductive parts while maintaining its sealing function, eliminating the need for separate insulation components and reducing assembly steps.

AI summary
Sealing arrangement for guiding an electrical connection through a wall of a housing for a device for driving a compressor having an electrically conducting connecting element, guided through a conical passage aperture of the housing, which at least regionally is fully enclosed over the entire circumference by a sealing element. Sealing element is formed as a hollow truncated cone and disposed between a conical sealing facing of the connecting element and a boundary surface of the passage aperture sealing the connecting element against the housing. The connecting element is disposed having been guided through a connection passage of a receiving member for receiving a plug housing with a wall into the plug housing. A device for driving a compressor of a gaseous fluid with the sealing arrangement and a method for assembling the device and use of the device are disclosed.
