USB 3.0 Receptacle Connector Plug Detection Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB 3.0 receptacle connectors fail to timely detect the insertion of a plug connector and provide electric power under a power-saving mode on printed circuit boards (PCBs).
Innovation Solution
A high frequency receptacle connector with a plug detecting assembly, comprising first and second detecting terminals, that selectively contacts or isolates to activate a power supplying circuit on the PCB, ensuring electric power is provided to external devices even during power-saving modes.

Engineering Contradiction Analysis
1Loss of energy
If a conventional USB 3.0 receptacle connector is used under power-saving mode, then power consumption is reduced, but the ability to detect plug insertion and provide power timely is lost
Solution Approach 1:
The resilient detecting terminal is pre-positioned to protrude into the plug connector insertion space before any plug is inserted. This preliminary positioning enables immediate detection capability as soon as a plug enters the receptacle, without requiring additional activation steps or power consumption for detection circuits.
Solution Approach 2:
The detecting terminal uses its own resilience to perform both detection and signal transmission functions. When a plug inserts, the terminal passively deflects and automatically establishes electrical contact, eliminating the need for separate active detection circuits or additional power management components.
2Difficulty of detecting and measuring
If a resilient detecting terminal is added to enable plug detection, then detection capability is improved, but device complexity increases
Solution Approach 1:
The resilient detecting terminal serves multiple functions simultaneously: it acts as a mechanical plug presence detector, an electrical signal transmission path, and a power transmission path. This multi-functionality eliminates the need for separate detection circuits, buttons, or sensors that would increase complexity.
Solution Approach 2:
The detecting terminal's electrical state changes automatically with its physical position. When protruding (no plug), it maintains one electrical state; when deflected by plug insertion, it transitions to another electrical state. This passive parameter change provides detection capability without requiring active control circuits.

AI summary
A high frequency receptacle connector has an insulating housing, multiple first terminals, multiple second terminals, a shell and a plug detecting assembly. The first and second terminals are mounted on the insulating housing and capable of implementing USB3.0 protocol. The shell covers the insulating housing and terminals. The plug detecting assembly has a first detecting terminal and a second detecting terminal. The first detecting terminal is mounted on the insulating housing. The second detecting terminal is mounted on the insulating housing and selectively bends to contact or isolate from the first detecting terminal. The high frequency receptacle connector is capable of providing electric power under a power-saving mode of a PCB on which the high frequency receptacle connector is mounted.
