Connector Anchoring Terminal Ring Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector sets face challenges in noise-resistance properties due to the limited reinforcement at the ends of the housing, leading to inadequate shielding of high-frequency signals.
Innovation Solution
A connector set design featuring a first and second connector with anchoring terminals connected to a ground potential, forming a ring shape around the contact portions to encircle and shield the connection terminals, enhancing noise resistance by suppressing noise entry and radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If reinforcing fittings are only provided at both ends of the housing in the longer direction, then device complexity is reduced, but noise-resistance properties deteriorate
Solution Approach 1:
The anchoring terminal is divided into multiple segments: a ring-shaped main body portion that provides comprehensive shielding, and multiple protruding portions that extend toward connection terminals. This segmentation allows the single terminal to perform multiple functions (shielding and grounding) without adding additional components, thus improving noise resistance while maintaining structural simplicity.
Solution Approach 2:
The anchoring terminal transitions from a simple linear or point-based structure to a ring-shaped structure with protruding portions extending in multiple directions. This dimensional change allows the terminal to encircle and shield connection terminals from noise in all directions (360-degree shielding), significantly improving noise resistance without proportionally increasing complexity.
2Object-affected harmful factors
If a ring-shaped anchoring terminal is used to encircle contact portions, then noise-resistance properties are improved, but manufacturing precision requirements increase
Solution Approach 1:
The anchoring terminal merges the grounding function and the shielding function into a single integrated component. The ring-shaped body provides grounding while simultaneously encircling connection terminals for noise shielding, and the protruding portions extend to provide additional shielding coverage. This merging eliminates the need for separate grounding and shielding components, improving noise resistance without proportionally increasing manufacturing complexity.
Solution Approach 2:
The anchoring terminal is designed as a multi-functional component that performs grounding, shielding, and mechanical support functions simultaneously. The ring-shaped structure with protruding portions can encircle multiple connection terminals and provide comprehensive noise protection, making it a universal solution that replaces multiple separate components and reduces overall assembly complexity.
3Reliability
If anchoring terminals make contact to maintain coupling, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The anchoring terminal combines the mechanical coupling function and the electrical grounding/shielding function into a single component. The ring-shaped structure with protruding portions maintains mechanical coupling between connectors while simultaneously providing grounding and noise shielding, eliminating the need for separate coupling and grounding components.
Solution Approach 2:
The anchoring terminal serves multiple functions: mechanical support for maintaining connector coupling, electrical grounding path provision, and noise shielding through its ring-shaped enclosure. This multi-functionality allows a single component to replace what would traditionally require multiple separate components, improving reliability without proportionally increasing complexity.

AI summary
A connector set includes a first connector and a second connector. The first connector has a plurality of first connection terminals, a first anchoring terminal, and a first insulative member, and the second connector has a plurality of second connection terminals, a second anchoring terminal, and a second insulative member. When the first connector and the second connector are coupled, the plurality of first connection terminals and the plurality of second connection terminals respectively make contact at the first contact portions and the second contact portions. The first anchoring terminal and the second anchoring terminal make contact with each other to maintain the coupling between the first connector and the second connector, and have a ring shape that encircles a periphery of the first contact portions and the second contact portions when the first connector and the second connector are coupled.
