Electrically Shielded Coupling Assembly with Latching Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrically shielded coupling arrangements fail to maintain effective shielding against high-frequency interference fields due to loose connections caused by dynamic movements, vibrations, and oscillations, which can lead to gaps or openings impairing the electrical shielding.
Innovation Solution
An electrically shielded coupling arrangement with a latching connection that ensures the coupling part and counter-coupling part contact each other under pretension, maintaining a tight seal and preventing electromagnetic interference, using a snap-in connection with differing diameters to secure the coupling parts and optionally a screw connection for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional coupling arrangements are used to connect cables to dynamically moving consumers, then the connection can be made easily, but the connections become loose due to oscillations and vibrations, leading to impaired electrical shielding
Solution Approach 1:
The coupling part is pre-tensioned in the closed contact area before final engagement, creating initial contact pressure that maintains shielding integrity. The latching projection is designed to engage with the latching undercut in a way that automatically applies prestress to the contact area, ensuring shielding reliability from the moment of connection without requiring additional adjustment steps.
Solution Approach 2:
The invention changes the mechanical parameters of the coupling arrangement by introducing a latching mechanism that transforms the connection from a loose fit to a pre-stressed engaged state. The latching projection and undercut create a mechanical interlock that maintains constant contact pressure, preventing gaps that would allow high-frequency interference fields to penetrate the shielding.
2Reliability
If the coupling part and counter-coupling part are connected without a latching mechanism, then the structure is simpler, but the connection loosens under dynamic movements causing gaps that impair shielding
Solution Approach 1:
The coupling arrangement is segmented into distinct functional elements: a coupling part with a latching projection, a counter-coupling part with a latching undercut, and a closed contact area for electrical connection. This segmentation allows each element to perform its specific function - the latching mechanism provides mechanical security while the closed contact area maintains electrical shielding, creating a modular design that is both effective and manufacturable.
Solution Approach 2:
The invention merges the mechanical latching function with the electrical shielding function in a single integrated coupling arrangement. The latching projection and undercut not only secure the connection mechanically but also maintain the closed contact area that provides electrical shielding. This combination eliminates the need for separate latching and shielding components, reducing overall complexity while maintaining both mechanical security and electromagnetic protection.

Function Achieved in This Case
The solution effectively prevents the entry of electromagnetic interference fields into the coupling arrangement, maintaining reliable shielding even under dynamic conditions, and secures the connection against unintentional loosening.
Implementation Method 1
the coupling part and the counter-coupling part contact each other under pretension in the closed circumferential contact area when the latching connection is engaged, so that the entry of electromagnetic interference fields into the interior of the coupling arrangement can be effectively prevented

AI summary
The invention relates to improvements in the technical field of electrically shielded coupling assemblies. In particular, an electrically complete coupling assembly (1) is proposed as an improvement, the coupling part (2) and mating coupling part (3) of which are secured by the locking connection (4) when the coupling assembly (1) is closed, wherein the coupling part (2) and the mating coupling part (3) are connected to each other under compression when the locking connection (4) is engaged, so that they contact each other under preload in a contact area (6) that is enclosed and rotates around a longitudinal axis (5) of the coupling assembly (1) (Fig. 1).
