Ground Contact Connector Beams for Tolerance-Stable Equalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector assemblies, such as those described in CN 113346285, face challenges in maintaining stable contact between electrical conductors with protrusions and contacts due to increased structural complexity and tighter tolerance requirements, making it difficult to ensure consistent contact across varying assembly conditions.
Innovation Solution
A ground contact connecting member with a support portion and contacting beams is integrated into the connector housing, allowing the beams to deflect and make stable contact with a ground contact group, even when the contacts' positions vary, thereby ensuring potential equalization and improved signal intensity performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electrical conductor with protrusions is used to make contacts equipotential, then potential equalization is achieved, but stable contact becomes difficult due to increased structural complexity and tighter tolerance requirements
Solution Approach 1:
The patent applies the dynamics principle by designing the ground contact connecting member with flexible contacting beams that can elastically deform. Instead of requiring precise fixed-position protrusions, the beams dynamically adapt their position to maintain contact with the ground contacts, allowing the system to accommodate tolerance variations while ensuring potential equalization.
Solution Approach 2:
The patent changes the physical state of the ground contact connecting member from a rigid structure with fixed protrusions to a flexible structure with elastically deformable beams. This parameter change allows the contacting beams to adjust their position and shape, ensuring stable contact with ground contacts despite manufacturing tolerances and assembly variations.
2Manufacturing precision
If the connector structure is made more complex to accommodate tighter tolerances, then contact stability improves, but device complexity increases
Solution Approach 1:
The patent employs flexible beams as thin-walled elastic structures that can deform to maintain contact. These flexible contacting beams replace complex rigid positioning mechanisms, achieving contact stability through elastic deformation rather than through complex structural arrangements, thus reducing overall device complexity while improving manufacturing tolerance robustness.
3Reliability
If protrusions are exposed through grooves to contact the contacts, then electrical connection is established, but assembly becomes sensitive to dimensional and form tolerances
Solution Approach 1:
The patent applies the self-service principle by designing the contacting beams to automatically adjust their position and shape through elastic deformation during assembly. The beams self-align with the ground contacts without requiring precise pre-positioning, allowing the assembly process to accommodate dimensional and form tolerances while ensuring reliable electrical connection for potential equalization.

AI summary
The invention provides an electrically conducting member capable of stable contact with a plurality of contacts subjected to potential equalization, a connector, and a connector assembly. A ground contact connecting member (70) contacting a ground contact group GG equivalent to some of respective contacts (10) of a first row R1 and a second row R2 adjacent to the first row R1 in a second direction y that are arranged along a first direction x in parallel includes a support portion (71) provided along the first direction x at an installation portion (33) of a connector housing (30), and a plurality of contacting beams (72) extending from the support portion (71) toward the first row R1 or toward the second row R2 and contacting the ground contact group GG. The contacting beams (72) are pressed against the contacts (10) of the ground contact group GG in a third direction z crossing both the first direction x and the second direction y.
