Shielding-Grounding Plate with Hooking Arms for Electrical Plug Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors lack a shielding element to prevent cross talk between terminal sets, leading to decreased signal transmission stability and efficiency, and they often fail to securely engage with corresponding receptacle connectors due to the absence of hooking elements.
Innovation Solution
An electrical plug connector with a shielding-grounding plate integrated between two sets of terminals and equipped with resilient hooking arms, which shields the terminals from cross talk and provides a secure engagement mechanism with a corresponding receptacle connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If no shielding element is mounted between the terminal sets, then the device complexity is reduced, but cross talk interference occurs between terminal sets during signal transmission
Solution Approach 1:
A shielding-grounding plate is introduced as an intermediary element positioned between the two terminal sets. This plate serves as a mediator that blocks electromagnetic interference and prevents cross talk between adjacent terminal sets, resolving the harmful interaction without requiring complex active control systems.
Solution Approach 2:
The shielding-grounding plate is divided into multiple segments including a first shielding portion for the first terminal set, a second shielding portion for the second terminal set, and a grounding portion. This segmentation allows each portion to independently shield its corresponding terminal set while the grounding portion provides a common reference potential, effectively isolating the terminal sets from each other.
2Reliability
If hooking elements are added to the electrical connector, then the engagement reliability with receptacle connector is improved, but the device complexity increases
Solution Approach 1:
The hooking arms are integrally formed with the shielding-grounding plate, merging the shielding function and the mechanical engagement function into a single component. This eliminates the need for separate hooking elements, reducing the overall number of parts while maintaining both shielding effectiveness and reliable engagement with the receptacle connector.
Solution Approach 2:
The shielding-grounding plate performs multiple functions simultaneously: it provides electromagnetic shielding for both terminal sets, establishes a grounding reference, and incorporates hooking arms for mechanical engagement with the receptacle connector. This multi-functionality reduces the need for additional components.
3Reliability
If a grounding plate is mounted between the terminal sets, then signal transmission stability is improved by preventing cross talk, but the device complexity increases
Solution Approach 1:
The grounding plate combines shielding functionality with grounding functionality in a single integrated component. The shielding portions extend over the terminal sets while the grounding portion provides a common reference potential, eliminating the need for separate shielding and grounding components.

AI summary
An electrical plug connector has an insulative housing, two terminal sets, a shielding-grounding plate and a shell. The terminal sets are mounted in the insulative housing and each terminal set has multiple conductive terminals. The shielding-grounding plate is mounted in a rear end of the insulative housing and has a shielding body mounted in the rear end of the insulative housing and located between the terminal sets and two resilient hooking arms formed on and protruding forward respectively from two opposite sides of the shielding body and extending in the insulative housing. The shielding-grounding plate is located above the conductive terminals of the two terminal sets and shields the terminal sets such that each terminal set would not interfere with the other terminal set with cross talk when implementing signal transmission.
