Two-Row Electrical Connector for Compact Width and Repair Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors with single-row contact terminating portions on the circuit board mounting side obstruct inspection or repair of soldering and result in a wider connector design, limiting the miniaturization of connectors with two-row contact end configurations on the mating face.
Innovation Solution
An electrical connector design featuring contact ends in two rows on the mating face and terminating ends in one row on the circuit board side, with a specific arrangement of differential signal carrying contacts and grounding contacts to maintain shielding performance and reduce overall dimensions, including a metal shield and resin housing with cantilevered arm members for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If contact terminating portions are arranged in one row on the circuit board mounting side, then inspection and repair of soldering becomes easier, but the connector width increases
Solution Approach 1:
The patent applies dimensionality change by transitioning from a conventional one-row configuration to a two-row configuration of contact terminating portions on the circuit board mounting side. This allows the connector to maintain a compact width while providing access to inner row contacts for inspection and repair, effectively solving the contradiction by utilizing a different spatial arrangement.
2Adaptability or versatility
If contact ends are positioned in two rows on the mating face, then signal transmission capability is improved, but connector width increases
Solution Approach 1:
The patent resolves this contradiction by implementing a two-row configuration of contact ends on the mating face while simultaneously using a two-row configuration of contact terminating portions on the circuit board side. This dimensional arrangement allows compact width while maintaining enhanced signal transmission capability through the increased contact density and configuration.
3Object-affected harmful factors
If grounding contacts are positioned adjacent to signal carrying contacts, then shielding performance is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by strategically positioning grounding contacts adjacent to signal carrying contacts in specific locations within the two-row configuration. This localized arrangement of grounding elements provides effective shielding and crosstalk reduction for critical signal paths without requiring complex grounding structures throughout the entire connector, thus balancing shielding performance with device complexity.

AI summary
An electrical connector is disclosed having a plurality of contacts. The plurality of contacts includes contact ends positioned in two rows and terminating ends positioned in one row. A first grouping of the plurality of contacts includes units of two differential signal carrying contacts having signal carrying contact ends connected to two signal terminating ends on a one to one ratio. The first grouping also includes grounding contacts positioned adjacent to the signal carrying contacts, and having grounding contact ends connected to grounding terminating ends with a ratio of the number of grounding contact ends being greater than or equal to the number of grounding terminating ends.
