Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector-equipped multicore cables experience increased noise levels as signal frequency rises, which is not adequately addressed by current technologies.
Innovation Solution
The connector-equipped multicore cable features a metal cover that electrically connects with the first shield layer of coaxial electrical wires, providing a ground potential and reducing noise through additional shielding and assembly features like metal plates and elastic members that enhance electrical connections and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector-equipped multicore cable uses conventional shielding without metal cover electrical connection, then the device complexity is reduced, but noise increases when signal frequency becomes higher
Solution Approach 1:
The patent combines the metal cover and shield layer into an integrated electrical connection system. The metal cover at the connector end is electrically connected to the shield layer of coaxial cables, merging two separate shielding elements into a unified noise protection system. This integration maintains signal integrity at high frequencies while avoiding the need for additional separate shielding components.
Solution Approach 2:
The patent establishes equipotential connection between the metal cover and shield layer through electrical connection. By connecting the metal cover to the shield layer, both elements are brought to the same electrical potential, creating an effective Faraday cage structure that prevents external electromagnetic interference from affecting internal signals, thereby reducing noise without requiring complex active shielding systems.
2Reliability
If the metal cover is electrically connected to the first shield layer, then noise is reduced through additional shielding, but the manufacturing complexity increases
Solution Approach 1:
The patent incorporates the electrical connection between the metal cover and shield layer as a built-in feature during connector assembly. The connector is designed with preliminary grounding structures that automatically establish electrical connection when the metal cover is installed, eliminating the need for separate post-assembly wiring steps. This preliminary integration simplifies the manufacturing process while maintaining effective noise shielding.
