Shielded Connector Adaptor for Universal Cable Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for electromagnetic shielding in motor vehicle wiring networks are not universally compatible, as they either require a shielding braid in the form of an independent sleeve or direct electrical continuity between the connector shielding and the cable shielding, without a flexible adaptation method.
Innovation Solution
An electrical shielding adapter with a conductive metal sheet and insulating plastic support, allowing for electrical continuity with either a shielding braid sleeve or a braided shielding within a cable, using clamps, flexible tabs, or ferrules for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shielding braid in the form of an independent sleeve is used to shield the junction between connector and cable, then electromagnetic shielding effectiveness is improved, but device complexity and number of components increase
Solution Approach 1:
The patent merges the shielding function with the existing cable shielding braid by creating direct electrical continuity between the connector shielding envelope and the cable shielding braid through conductive elements (ferrules, tabs, or direct contact). This eliminates the need for a separate independent shielding sleeve, reducing component count while maintaining shielding effectiveness.
Solution Approach 2:
The patent creates a universal shielding solution that works with both shielded and unshielded cables by providing multiple implementation options (direct contact, ferrules, flexible tabs). The same basic adapter structure can accommodate different cable types and shielding configurations, making the solution universally applicable without requiring additional specialized components.
2Device complexity
If direct electrical continuity is established between connector shielding and cable shielding braid, then device complexity is reduced, but adaptability to different shielding configurations is limited
Solution Approach 1:
The patent employs flexible tabs that can dynamically adapt to different cable configurations. These tabs can bend and conform to accommodate both shielded and unshielded cables, as well as different braid diameters and positions, providing adaptability without requiring multiple fixed-configuration components.
Solution Approach 2:
The patent uses intermediary elements such as ferrules and flexible tabs that act as mediators between the connector shielding and the cable shielding braid. These intermediaries provide a universal interface that can accommodate different shielding configurations, enabling adaptability while maintaining a simple overall structure.
3Adaptability or versatility
If multiple shielding solutions are provided for different cable types, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent designs a universal adapter structure that can accommodate both shielded and unshielded cables through a single basic design. The adapter includes optional elements (ferrules, flexible tabs) that can be incorporated as needed, but the core structure remains the same, providing adaptability without requiring multiple different component types.
Solution Approach 2:
The patent segments the shielding adaptation function into modular elements (ferrules, flexible tabs, direct contact options) that can be selectively used based on the specific cable configuration. This allows the basic adapter structure to remain simple while providing specialized elements only when needed for specific shielding scenarios.
