Connecting Arrangement for Sealed and Non-Sealed Plug Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements between electrical or electronic devices and plug connection units either require environmentally sealed connections to prevent moisture and dirt ingress or allow leakage, but not both, due to design limitations that affect accurate positioning of electrical connections.
Innovation Solution
A connection arrangement where the plug housing can accommodate either a sealing element or a modified positioning device/bridging element, ensuring precise positioning of electrical connections, allowing for both sealed and non-sealed connections using the same device and connector housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing element is used to ensure sealed connection, then sealing performance is improved, but device complexity increases
Solution Approach 1:
The patent combines the sealing element with the positioning device into a single integrated component. The positioning device includes positioning elements that simultaneously provide mechanical positioning and sealing functions, eliminating the need for separate sealing elements and reducing overall device complexity while maintaining reliable sealing performance.
Solution Approach 2:
The positioning device is designed to perform multiple functions: it positions the electrical connections axially and laterally while simultaneously providing sealing through integrated sealing elements. This multi-functional design reduces the number of components needed and simplifies the overall connection arrangement.
2Device complexity
If sealing elements are omitted for non-sealed connections, then device complexity is reduced, but manufacturing precision requirements worsen
Solution Approach 1:
By integrating sealing elements into the positioning device, the patent ensures that positioning accuracy is maintained through the mechanical structure of the positioning elements themselves. The positioning device's geometry and material properties provide precise positioning regardless of whether sealing is required, eliminating the need for separate sealing components that would add complexity.
3Reliability
If separate sealing elements are used for sealed connections, then sealing performance is improved, but ease of manufacture worsens
Solution Approach 1:
The sealing elements are integrated into the positioning device as a single component, which can be manufactured using standard injection molding or similar processes. This integration eliminates the need for separate assembly steps for sealing elements and simplifies the manufacturing process while ensuring consistent sealing performance through precise integration of the sealing function into the positioning structure.
