Shielded High Density Jack Wrap-Around Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional shielding techniques for voice/data/video connectors result in additional shielding failures and increased contact resistance over time, leading to degradation of cable performance and impedance changes, due to multiple connections and separation of shielded cables from foils, as well as the use of multiple components that are prone to degradation from temperature cycling.
Innovation Solution
A modular electrical connector assembly with a direct shielding connection using a wrap-around shield contact and a copper alloy plug contact, which captures the cable shield without separating it, reducing the number of connection points and maintaining contact through a single, continuous connection that includes spring-like features and integrated hooks to retain the drain wire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple connections and separation of shielded cable from foil are used, then cable flexibility and ease of assembly are improved, but contact resistance increases and shield performance degrades over time
Solution Approach 1:
The patent merges the cable shield and foil into a single continuous shielding structure that maintains electrical contact throughout the connector assembly. Instead of separating the shielded cable from the foil as in conventional designs, this invention integrates them so that the foil remains in continuous contact with the cable shield along the entire length, preventing contact resistance buildup and maintaining shield effectiveness over time while still allowing cable flexibility.
2Strength
If multiple components (cable clamps, plastic ties) are used to maintain contact during flex, then cable retention is improved, but contact resistance increases and performance degrades over time
Solution Approach 1:
The patent removes multiple discrete components (cable clamps, plastic ties) from the shielding assembly and replaces them with a single integrated continuous foil structure. This extracted simplified design maintains cable retention through the continuous mechanical and electrical connection of the foil to the cable shield, eliminating the multiple contact points that would otherwise increase contact resistance and fail over time.
3Ease of manufacture
If conventional shielding techniques are used, then assembly simplicity is maintained, but additional shielding failures occur and contact resistance increases over time
Solution Approach 1:
The invention combines multiple shielding functions into a single continuous foil structure that performs both mechanical retention and electrical shielding in one integrated component. This merged design maintains assembly simplicity while eliminating the multiple connection points and separation issues of conventional techniques, thereby preventing shielding failures and contact resistance buildup over time.
