Cable-Mounted USB 3.0 Receptacle Connector Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB 3.0 receptacle connectors are not designed for cables, resulting in insufficient bandwidth for high-speed data transmission between electronic devices, as they are typically mounted on printed circuit boards only.
Innovation Solution
A receptacle connector for cables is developed, featuring an insulating housing with first and second terminals, each with soldering cups, and a shell that covers them, allowing for USB 3.0 protocol implementation by securely mounting on the cable for high-speed data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional USB 2.0 connectors are used, then compatibility with existing devices is maintained, but data transmission speed is insufficient for modern electronic devices
Solution Approach 1:
The receptacle connector is designed to support both USB 2.0 and USB 3.0 protocols through the inclusion of two sets of terminals (first terminals for USB 2.0 and second terminals for USB 3.0). This multi-functionality allows the connector to adapt to different protocol requirements while maintaining backward compatibility, resolving the contradiction between speed improvement and compatibility preservation
2Speed
If USB 3.0 receptacle connectors are mounted on printed circuit boards, then high-speed data transmission is enabled, but cable-mounted connectors are not available limiting bandwidth for mobile devices
Solution Approach 1:
Instead of adapting PCB-mounted connectors for cable use, the invention inverts the approach by specifically designing a cable-mounted receptacle connector that integrates USB 3.0 functionality directly into the cable interface. This inversion enables high-speed data transmission in cable applications where it was previously unavailable, resolving the contradiction between speed and adaptability to cable connections
3Speed
If a cable-mounted USB 3.0 receptacle connector is implemented, then high-speed data transmission is enabled, but the connector structure becomes more complex compared to conventional connectors
Solution Approach 1:
The connector employs a nested structure where the insulating housing contains multiple sets of terminals (first terminals and second terminals) that are integrated within a single connector body. The shell further encloses these components, creating a compact nested arrangement. This nesting approach enables USB 3.0 functionality without proportionally increasing overall connector complexity, as multiple functions are packed into a unified structure

AI summary
A receptacle connector for a cable has an insulating housing, multiple first terminals, multiple second terminals and a shell. The first terminals are mounted on the insulating housing and each first terminal has a first soldering cup formed on the first terminal and extending backward out of the insulating housing. The second terminals are mounted on the insulating housing, are capable of cooperating with the first terminals to implement USB 3.0 protocol and each second terminal has a second soldering cup formed on the second terminal and extending backward out of the rear end of the insulating housing. The shell covers the insulating housing, the first terminals and the second terminals. The receptacle connector may be mounted one end of the cable so that cable is used for high speed data transmission between different electronic devices.
