Communication Connector Metal Partition Wall Impedance Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication connectors experience reduced communication quality due to impedance changes and signal reflection when wires are exposed after the removal of their coating, leading to space constraints and signal degradation, especially with high-speed wires.
Innovation Solution
A communication connector design featuring metal partition walls between wires to stabilize impedance, a compact housing arrangement, and a metal tape for shielding, which includes locking alignment members to maintain wire position and suppress signal degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wires are exposed by removing coating for connection, then connection is enabled, but impedance changes and signal reflection occur reducing communication quality
Solution Approach 1:
A metal partition wall is introduced as an intermediary structure between adjacent exposed wires. This partition wall acts as a mediator that maintains stable impedance by providing a consistent reference plane, thereby preventing signal reflection and maintaining communication quality while allowing wire exposure for connection.
Solution Approach 2:
The metal partition wall is specifically positioned only where needed - between adjacent exposed wires at the connection point. This localized structure provides impedance stabilization precisely where the coating removal creates vulnerability, without adding unnecessary complexity elsewhere in the cable assembly.
2Ease of operation
If terminals are arranged side by side in one stage, then connection is simplified, but the connector becomes longer increasing space restrictions
Solution Approach 1:
The housing is designed with multi-stage arrangement of terminals, transitioning from a single-row linear arrangement to a multi-level three-dimensional configuration. This dimensional change allows terminals to be organized in multiple stages along the length direction, reducing the overall connector length while maintaining accessibility for connection operations.
3Manufacturing precision
If alignment members are provided without locking portions, then wire alignment is achieved, but relative displacement causes wire lifting reducing reliability
Solution Approach 1:
Locking portions are pre-formed on the alignment members during manufacturing. These locking structures are prepared in advance to engage with corresponding features on adjacent components, preventing any subsequent relative displacement that would cause wire lifting, thereby ensuring long-term position stability.
4Device complexity
If no shielding is provided for high-speed wires, then device complexity is reduced, but signal degradation from reflection and radiation increases
Solution Approach 1:
The metal partition wall is selectively positioned between high-speed wires that are susceptible to signal degradation, rather than providing universal shielding for all wires. This localized shielding approach addresses the specific needs of high-speed signal transmission while minimizing overall device complexity.
