Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RJ45 connectors lack efficient crosstalk reduction and shielding, complicating cable strand connection and failing to provide a ground connection, which are essential for high-density patch panels and increasing data transfer rates amidst electromagnetic disturbances.
Innovation Solution
A female socket design featuring parallel plates with insulation displacement contacts oriented in the same direction, a separate connection module with slots for shielded cable strands, and a connecting element with electrical contact zones to ensure shielding, allowing for simultaneous connection of all strands and reducing crosstalk through partitioning and electrical shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of wires is increased to meet higher data transfer rates, then the data transfer capability is improved, but the connector size and complexity increase
Solution Approach 1:
The connector is divided into two distinct parallel plates, each containing a row of contacts. This segmentation allows the connector to handle multiple wires (up to 8) while maintaining a compact structure, as each plate can be independently managed and assembled.
Solution Approach 2:
The invention transitions from a single-plane contact arrangement to a three-dimensional structure with two parallel plates. This dimensional change allows contacts to be arranged in multiple planes, increasing the number of wires that can be connected without proportionally increasing the connector's footprint.
2Object-affected harmful factors
If shielding is improved to reduce electromagnetic disturbances, then the anti-interference capability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The shielding structure is segmented into two parallel plates with distinct contact rows, allowing independent optimization of each plate's shielding characteristics. This segmentation makes it easier to implement effective grounding and shielding without requiring a completely redesigned complex structure.
Solution Approach 2:
Each plate is designed with specific local shielding characteristics tailored to its contact arrangement. The parallel plate structure allows different shielding strategies to be applied to each plate, optimizing electromagnetic interference protection for each wire pair independently.
3Ease of operation
If all strands are connected simultaneously in a single movement, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The connection mechanism is divided into two independent plate assemblies, each capable of simultaneous contact engagement. This segmentation allows the connector to achieve multi-point contact in a single insertion motion while reducing the overall precision requirements compared to a single complex multi-contact mechanism.
Solution Approach 2:
The design allows for slight variations in contact timing between the two plates, accepting that not all contacts engage at perfectly simultaneous moments. This partial action approach maintains ease of operation while relaxing the stringent precision requirements that would be needed for perfectly synchronized multi-point contact.
4Adaptability or versatility
If the connector size is maintained while increasing wire count, then the adaptability for high-density applications is improved, but the manufacturing difficulty increases
Solution Approach 1:
The connector is manufactured as two separate parallel plate assemblies that can be produced independently using standard manufacturing processes. This segmentation allows each plate to be manufactured with conventional techniques, reducing overall manufacturing difficulty while achieving high wire density in the final assembled connector.
Solution Approach 2:
The two parallel plate structures are nested or closely positioned within a compact housing, allowing the connector to accommodate multiple wires in a small volume. This nesting arrangement achieves high-density configuration while maintaining manufacturability through modular assembly of the plate components.
