Electrical Connector Terminals With Identical Structures For Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in preventing electromagnetic interference due to the complexity of distinguishing between signal and grounding terminals, leading to increased processing difficulty and assembly errors that compromise the shielding effect and anti-interference ability.
Innovation Solution
The design features terminals with identical structures, including a base, an elastic arm, and strip connecting portions, where the shielding member has abutting portions that contact the grounding terminals, eliminating the need for distinguishing between terminal types during assembly and ensuring proper shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal terminals are designed without extending portions to prevent short-circuiting with the shielding member, then short-circuiting is prevented, but the structure of signal terminals becomes different from grounding members, increasing processing difficulty
Solution Approach 1:
The patent applies universality by making signal terminals and grounding members have identical structures. Both terminal types include the same base, elastic arm, and extending portion configuration. This standardized design allows the same mold and processing steps to be used for both terminal types, reducing manufacturing complexity while maintaining the shielding function through the extending portions that contact the shielding member.
2Reliability
If signal terminals have different structures from grounding members to prevent abutting the shielding member, then short-circuiting is avoided, but assembly errors increase as operators may easily assemble signal terminals in the grounding member's accommodating tube by mistake
Solution Approach 1:
The patent makes both signal terminals and grounding members have identical structures with the same base, elastic arm, and extending portion features. This standardization eliminates visual and structural differences that could lead to assembly errors, while the extending portions ensure proper contact with the shielding member when assembled correctly in their respective accommodating tubes.
Solution Approach 2:
The patent applies local quality by providing extending portions specifically on the terminal bodies that contact the shielding member, while keeping other parts of the terminals identical. The extending portions are localized features that enable the shielding function without making the entire terminal structure different between signal and grounding types.
3Object-affected harmful factors
If grounding members have extending portions contacting the shielding member to achieve shielding effect, then electromagnetic interference is prevented, but the structure becomes more complex compared to simple terminal designs
Solution Approach 1:
The patent makes the extending portion a universal feature of all terminals (both signal and grounding), rather than a specialized feature only of grounding members. This allows all terminals to potentially contact the shielding member, providing shielding functionality across the connector while maintaining structural simplicity through standardization.
Solution Approach 2:
The patent merges the shielding function into the basic terminal structure by integrating the extending portion directly into the terminal body. This combines the electrical connection function and the shielding contact function into a single integrated component design, reducing the need for separate shielding structures.

AI summary
An electrical connector includes an insulating body, multiple terminals respectively correspondingly accommodated in the insulating body, and a shielding member provided on the insulating body. The terminals includes at least one grounding terminal and at least one signal terminal having identical structures. Each terminal includes a base, an elastic arm bending upward and extending from the base for being conductively connected with a chip module, and at least one strip connecting portion formed by extending upward from the base for being connected with a strip. The shielding member is provided with multiple holes for the grounding terminal and the signal terminal to pass therethrough, and at least one abutting portion corresponding to the strip connecting portion of the grounding terminal and protrudingly extending toward at least one of the holes so as to be in contact with the strip connecting portion of the grounding terminal.
