Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metal shields for electrical connectors do not guarantee direct and reversible shield transfer, require auxiliary means like screws or crimping, and cannot be adapted to various conductor cross-sections, leading to potential transmission malfunctions.
Innovation Solution
A metal shield with a latching mechanism, comprising U-shaped coupling portions and detent lugs/recesses, allowing secure, reversible, and adaptable contact with conductors of different cross-sections, ensuring reliable shielding without destructive disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If auxiliary means such as screws, cable fasteners or crimp regions are used for shield transfer, then the shield transfer can be achieved, but the complexity of the device increases and the shield linkage cannot be disconnected non-destructively
Solution Approach 1:
The patent removes auxiliary means (screws, cable fasteners, crimp regions) from the shield transfer mechanism. The shield linkage directly contacts the conductor shield through the contact element without requiring external fastening components, thereby reducing device complexity while maintaining reliable shield transfer.
Solution Approach 2:
The shield linkage performs its own shielding function without requiring separate auxiliary components. The contact element with latching mechanism provides both mechanical retention and electrical shielding contact in a single integrated component, eliminating the need for additional screws or fasteners.
2Reliability
If crimped shield linkages are used, then the shield transfer can be secured, but the shield linkage cannot be disconnected non-destructively
Solution Approach 1:
The patent transitions from a static crimped connection to a dynamic latching mechanism. The contact element can be opened and closed repeatedly to establish and break electrical contact with the shield, allowing non-destructive disconnection and reconnection without damaging the conductor or shield linkage.
Solution Approach 2:
The shield linkage is divided into separable components: the contact element with latching mechanism can be independently opened and closed. This segmentation allows the electrical contact to be made or broken without applying destructive forces to the conductor or shield.
3Reliability
If metal shields are designed for specific conductor cross-sections, then the shield transfer is optimized, but the adaptability to various conductor sizes is reduced
Solution Approach 1:
The contact element with latching mechanism serves multiple functions: it provides mechanical retention for the conductor, establishes electrical contact with the shield, and adapts to various conductor cross-sections. The latching mechanism can accommodate different conductor sizes while maintaining reliable shield transfer, eliminating the need for multiple specialized shield designs.
Solution Approach 2:
The latching mechanism allows adjustment of the contact pressure and engagement geometry to accommodate different conductor cross-sections. By changing the latching position and contact force parameters, the same shield structure can reliably transfer shielding to conductors of varying sizes.
4Reliability
If frequent and extensive contacting of the cable shield is required, then the shield transfer is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines the electrical contact function and shield transfer function into a single integrated contact element. The latching mechanism simultaneously provides mechanical retention and electrical contact, eliminating the need for separate components and reducing manufacturing complexity while achieving frequent and extensive shield contacting.
