High-Speed Connector Isolation Structure for Signal Noise and Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-speed connectors suffer from signal interference and noise, especially at high frequencies, due to the exposure of terminal portions and inadequate insulation, which affects waterproofness and signal transmission quality.
Innovation Solution
A high-speed connector design featuring a metal shielding base with an isolation plate and partition plate, along with terminal modules that include an insulator covering the terminal legs and a protruding structure for enhanced waterproofing and signal isolation, reducing signal interference and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If terminals are assembled separately into the insulating layer, then assembly flexibility is improved, but terminal exposure increases reducing waterproofness and high-frequency signal quality
Solution Approach 1:
The isolation plate acts as an intermediary component that surrounds the exposed terminal leg portions. It provides both waterproof protection by covering the terminal exposure and electromagnetic shielding by blocking high-frequency signals, thus resolving the problems caused by separate terminal assembly
Solution Approach 2:
The isolation plate functions as a shielding shell that envelops the terminal leg portions. This thin-walled structure effectively blocks electromagnetic interference while maintaining the flexibility of separate terminal assembly, protecting exposed terminals without requiring complete reconfiguration of the assembly process
2Reliability
If terminal leg portions are exposed to prevent separation, then terminal retention is improved, but waterproofness and high-frequency signal transmission quality deteriorate
Solution Approach 1:
The isolation plate serves as a mediator that maintains the necessary terminal exposure for retention while simultaneously providing protection. It allows the terminal leg portions to remain exposed enough for mechanical retention but shields them from water and high-frequency electromagnetic interference
Solution Approach 2:
The isolation plate applies localized shielding only where needed - surrounding the terminal leg portions that require both retention and protection. This local quality approach maintains terminal functionality while addressing waterproofness and signal quality issues at the specific exposure locations

AI summary
The disclosure discloses an automotive connector, which includes a main body and a barrier component. A plurality of terminals are disposed in the main body. An end of each of the terminals is exposed from a bottom of the main body. The barrier component includes a partition plate and an isolation plate located on a side of the partition plate. The isolation plate is provided with the same number of through holes as terminal modules. When the partition plate is embedded in the main body, the partition plate is installed at the bottom of the main body. The through holes are used for terminals to pass through and to separate the terminals. This automotive connector can isolate each terminal module from each other by designing the partition and isolation plates, so as to avoid signal interference, significantly reduce noise, and be suitable for high-frequency scenarios.
