Electrical Connector Spacer for Cross-Talk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors experience heavy cross-talk between first and second extending portions, affecting data transmission quality due to the proximity of these components.
Innovation Solution
The electrical connector features a spacer with a lump extending upwardly, which separates the first and second groups of contacts along the front-to-rear direction, preventing cross-talk by maintaining them in distinct rows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the first and second extending portions are arranged adjacent to each other to reduce connector size, then the connector becomes more compact, but heavy cross-talk occurs between the contacts affecting data transmission
Solution Approach 1:
The patent introduces a spacer as an intermediary component between the first and second extending portions of the contacts. The spacer includes a first through hole for the first extending portion and a second through hole for the second extending portion, physically separating these adjacent contacts. This intermediary structure prevents direct electromagnetic coupling between the contacts while maintaining the compact connector design, thereby resolving the cross-talk issue without significantly increasing overall connector size.
2Object-affected harmful factors
If the first and second extending portions are separated to reduce cross-talk, then signal transmission quality improves, but the connector size and complexity increase
Solution Approach 1:
The patent merges the spacer with the insulative housing by integrating the spacer into the housing structure. The spacer is positioned within the housing and works cooperatively with the housing to provide both mechanical support and electromagnetic isolation. This merging approach allows the spacer to perform its separation function while being part of the overall housing structure, thereby reducing the number of discrete components and simplifying the overall connector assembly process.

AI summary
An electrical connector 100 includes an insulative housing 1, a plurality of contacts 2 retained in the insulative housing 1 and a spacer 3 mounted in the insulative housing 1. The contacts 2 include a plurality of first contacts 210 each having a first extending portion 213 extending downwardly and a plurality of second contacts 220 each having a second extending portion 223 extending downwardly. The first extending portions 213 and the second extending portions 223 form two rows, respectively. The spacer 3 includes a base 31 and a lump 33 extending upwardly from the base 31. The lump 33 separates the first extending portions 213 from the second extending portions 223 along a front-to-rear direction to improve signal transmission quality of the electrical connector 100.
