Electrical Connector Terminal Array Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors experience electromagnetic crosstalk between wire terminals, which impairs signal transmission speed and can render the connector inoperable, and they often have limited space to accommodate different wire sizes, restricting compatibility with various cables.
Innovation Solution
The electrical connector features a terminal array with second and first terminals, where the wire contacts of the second terminals are positioned closer to the wire end and are offset from those of the first terminals, allowing for differential pair separation and accommodating different wire sizes through a stepped configuration that reduces crosstalk and enhances signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If wire terminals are positioned in close proximity to one another, then the connector can accommodate more terminals in limited space, but electromagnetic crosstalk occurs between the wire terminals
Solution Approach 1:
The patent positions wire terminals at different distances from the wire end along the length dimension, creating a stepped configuration where first terminals are at a first distance and second terminals are at a second distance. This dimensional arrangement separates terminals that would otherwise be in close proximity, reducing electromagnetic crosstalk while maintaining high terminal density within the connector housing.
2Volume of moving object
If wire terminals are positioned in close proximity to one another, then the connector structure remains compact, but signal transmission speed is reduced due to crosstalk
Solution Approach 1:
By arranging terminals at different positions along the length of the housing rather than uniformly distributed in a single plane, the patent achieves spatial separation that reduces crosstalk and improves signal transmission speed, while the overall connector volume remains compact due to the efficient use of the housing length dimension.
3Device complexity
If wire terminals are positioned in close proximity to one another, then the connector structure is simplified, but the connector cannot accommodate different sizes of wire
Solution Approach 1:
The patent creates different local environments within the connector by positioning first terminals at a first distance from the wire end and second terminals at a second distance, allowing each terminal location to accommodate different wire sizes and types. This local differentiation enables the connector to handle various wire gauges and configurations without requiring a completely different connector design.
Solution Approach 2:
The stepped arrangement of terminals along the length dimension provides varying access spaces for wire insertion and termination, allowing the connector to accommodate different wire sizes. Larger wires can be terminated at terminals positioned further from the wire end, while smaller wires can be terminated at terminals closer to the wire end, all within the same connector structure.

AI summary
An electrical connector is provided. The connector includes a housing having a wire end and a mating end. A terminal array extends between the wire end and the mating end of the housing. The terminal array has second terminals and first terminals. Each of the second terminals and the first terminals has a wire contact positioned at the wire end of the housing and a mating contact positioned at the mating end of the housing. The wire contact of each second terminal is positioned closer to the wire end of the housing than the wire contact of each first terminal. The mating contacts of the second terminals are positioned adjacent the mating contacts of the first terminals.
