Shielded Terminal Module Structure for Connector Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors have poor shielding effects, which are inadequate for meeting increasing signal transmission requirements due to the limited coverage of conductive housings and mounting blocks, leading to inefficiencies in signal transmission and potential short circuits.
Innovation Solution
The implementation of a conductive housing and conductive cover plate configuration that fully covers the signal elastic arm, middle, and tail portions of signal terminals, along with integrated insulating and ground plates, to enhance shielding and prevent short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conductive housing and mounting block configuration is used to support signal terminals, then the structural support is provided, but the shielding effect is poor due to limited coverage and junction gaps
Solution Approach 1:
The patent merges the conductive housing and mounting block into an integrated structure where the mounting block is formed as an integral part of the conductive housing. This eliminates the junction gap between separate components and provides continuous shielding coverage along the signal terminal, resolving the shielding effectiveness issue while reducing structural complexity.
Solution Approach 2:
The conductive housing is segmented into multiple functional portions: a first portion that covers the signal elastic arm, a second portion that covers the middle portion of the signal terminal, and a third portion that covers the tail portion. This segmentation ensures comprehensive shielding coverage of all signal terminal sections while maintaining structural integrity.
2Reliability
If the conductive housing covers only part of the signal terminal, then the structure is simpler, but the shielding coverage is insufficient leading to signal transmission issues
Solution Approach 1:
The conductive housing is divided into three distinct portions along the length direction: a first portion covering the signal elastic arm, a second portion covering the middle portion, and a third portion covering the tail portion. This segmentation strategy ensures that each critical section of the signal terminal is adequately shielded, achieving comprehensive coverage without excessive structural complexity.
3Reliability
If separate mounting blocks and conductive housing are used, then manufacturing is easier, but the junction between parts creates poor shielding effect
Solution Approach 1:
The mounting block is integrated into the conductive housing as a single molded component rather than separate parts. This merging eliminates the junction gap that would exist between separate components, ensuring continuous shielding effectiveness while simplifying the manufacturing process through single-step molding.
