Plug Connector Shield Support for Post-Assembly Cable Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connections require excessive effort to connect the shield of a cable to the mating plug connector part, often necessitating the replacement of the already-mounted and soldered plug connection, especially during approval tests when interference radiation is detected, due to the dual-use shielding design.
Innovation Solution
A plug connector part with a housing featuring multiple plug-in portions, a shield connection, and a shield support that can be electrically connected via a connecting element, allowing for subsequent shielding potential transfer without replacing the plug connector or mating plug connector parts, enabling versatile and needs-based usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual-use shielding design is used in the plug connection, then the shielding provides both mechanical support and electrical shielding, but the assembly effort increases disproportionately when shield connection is needed after mounting
Solution Approach 1:
The invention separates the shielding function into two independent components: a shield support element that provides mechanical support and positioning, and a shield connection element that establishes electrical connection. This segmentation allows the shield support to be mounted during initial assembly while the shield connection can be added later if needed, eliminating the need to replace the entire plug connection and reducing assembly effort.
Solution Approach 2:
The shield support element is designed to be mounted in advance during the initial plug connection assembly, preparing the structure for future shield connection. This preliminary action enables the cable shield to be connected to the mating plug connector part later if interference radiation is detected, without requiring replacement of the already-mounted plug connection.
2Reliability
If the plug connection is already mounted and soldered, then the electrical connection is established, but replacing it to add shield connection involves disproportionately increased effort
Solution Approach 1:
By segmenting the shielding functionality into separate support and connection elements, the invention allows the electrical connection to remain intact while adding shield connection capability. This eliminates the need to replace the entire plug connection assembly and reduces the time loss associated with replacement.
Solution Approach 2:
The invention creates a dynamic assembly where the shield connection element can be added or removed based on actual shielding needs. This dynamic approach allows the system to adapt from a simple electrical connection to a shielded connection without requiring complete replacement, reducing time loss.
3Object-affected harmful factors
If shielding is integrated into the plug housing, then the shielding is always present, but the plug connection cannot be used without shielding in applications where it is not needed
Solution Approach 1:
The invention separates the shielding function into an optional shield connection element that can be added when interference radiation is detected. This allows the plug connection to be used in both shielded and unshielded applications, providing usage flexibility while protecting against harmful interference when needed.
Solution Approach 2:
The shield support element serves multiple functions: it provides mechanical support for the cable shield, enables electrical connection to the mating plug connector part, and allows the system to adapt to different application requirements. This multi-functionality increases usage flexibility while maintaining protection capability.
