Reversible Receptacle Connector Bridge Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reversible receptacle connectors with a single conductive bridge close to the printed circuit board (PCB) introduce undesirable capacitance, leading to crosstalk and degradation of signal quality, limiting bandwidth.
Innovation Solution
Incorporating a second conductive bridge closer to the connector, separated from the first bridge, to reduce capacitance and crosstalk by connecting the contacts at a different location, with the second bridge penetrating the insulating member and the first bridge being separated from it, ensuring the distance between them is less than 15 mm/√{εr} to minimize signal interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single conductive bridge is used close to the printed circuit board, then the device complexity is reduced, but the signal quality deteriorates due to increased capacitance and crosstalk
Solution Approach 1:
The conductive bridge is divided into two separate segments: a first conductive bridge close to the printed circuit board and a second conductive bridge closer to the connector. This segmentation reduces the capacitance effect by breaking the continuous conductive path, thereby reducing crosstalk and improving signal quality while maintaining manageable device complexity
2Ease of manufacture
If the conductive bridge is placed close to the printed circuit board, then the manufacturing is simplified, but the bandwidth is limited due to increased open stub capacitance
Solution Approach 1:
By segmenting the conductive bridge into two parts positioned at different locations, the patent reduces the effective capacitance that limits bandwidth. The first bridge maintains manufacturing simplicity near the PCB while the second bridge closer to the connector reduces the capacitive effect, thereby increasing signal transmission speed and bandwidth
3Device complexity
If a single conductive bridge configuration is used, then the device structure is simplified, but crosstalk increases due to open stub capacitance
Solution Approach 1:
The conductive bridge is segmented into two separate bridges at different positions along the contact path. This segmentation reduces the capacitive coupling between signal lines by breaking up the continuous conductive structure, thereby reducing crosstalk while maintaining reasonable structural complexity
Solution Approach 2:
The insulating member acts as an intermediary between the two conductive bridges, providing electrical isolation and controlling the capacitance effect. This intermediary structure allows the patent to reduce crosstalk while maintaining manageable device complexity

AI summary
Embodiments relate to a receptacle assembly for connecting to a plug of a connector. The receptacle includes a first contact on a first side of an insulating member. The first contact electrically connects to a first plug contact when the connector engages with the receptacle in a first orientation. The receptacle includes a second contact on a second side of the insulating member. The second contact electrically connects to the first plug contact when the connector engages with the receptacle in a second orientation. The second contact extends to a printed circuit board and is connected to the first contact via a first conductive bridge at a first location closer to the printed circuit board than the first plug contact. The first and second contacts are connected via a second conductive bridge at a second location closer to the first plug contact than the first conductive bridge.
