Socket Connector with Detection Switch for USB and eSATA
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing socket connectors with shared USB and eSATA terminals face signal misjudgment and distortion due to uneven terminal lengths and widths, and lack a detection switch for alternating plug-in functionality, leading to inefficient signal transmission and lack of detection capabilities.
Innovation Solution
A socket connector design with a detection switch and shared terminals of similar lengths and widths, featuring a pressure contact part that triggers the switch when a USB plug-in connector is inserted, allowing for efficient signal transmission and detection functions, while preventing eSATA plug-in from triggering the switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If shared USB and eSATA terminals are arranged with different pitches, then the connector supports both USB 3.0 and eSATA plug-in connectors, but the signal path length increases causing signal misjudgment and distortion
Solution Approach 1:
The patent segments the terminal arrangement into two distinct groups: eSATA terminals arranged in one pattern and USB terminals arranged in another pattern. This segmentation allows each terminal type to have its own optimized pitch and signal path, preventing signal distortion while maintaining compatibility with both connector types.
Solution Approach 2:
The patent applies local quality by giving different spatial arrangements to different terminal types. eSATA terminals are positioned with specific pitch requirements for eSATA signal integrity, while USB terminals are positioned with different pitch requirements for USB signal integrity. Each terminal type receives localized optimization rather than a uniform arrangement.
2Adaptability or versatility
If the connecting part extends toward the outer side to accommodate pitch differences, then both connector types can be supported, but the transmission path shrinks causing resistance increase and signal delay
Solution Approach 1:
The patent resolves the transmission path issue by changing the dimensional arrangement of terminals. Instead of extending the connecting part in one dimension which shrinks the transmission path, the patent arranges terminals in different spatial dimensions and patterns, allowing adequate transmission path length to be maintained while still supporting both connector types.
3Device complexity
If no detection switch is provided, then the connector structure remains simple, but the connector cannot detect plug-in status or switch signal transmissions between different types
Solution Approach 1:
The patent introduces a detection switch as an intermediary component that mediates between the physical plug-in action and the signal transmission switching. The detection switch detects which connector type is plugged in and automatically routes signals through the appropriate terminals, enabling dual connector support without requiring complex control systems.
Solution Approach 2:
The detection switch enables the connector to automatically detect and adapt to the plugged-in connector type without external intervention. The system self-services by automatically switching signal paths based on the detected plug-in status, eliminating the need for manual configuration or complex external control.

AI summary
A socket connector comprises a housing, a shield covering the housing and a detecting switch mounted in the housing. The housing includes a base and a pinboard having a first board surface and a second board surface. An eSATA terminal set having seven terminals side by side is mounted on the first board surface. An USB terminal set having nine terminals is mounted on the second board surface and five terminals are connected to the five middle terminals of the eSATA terminal set to form a shared terminal structure. The shield has a shared inserting room which includes a first inserting room for connecting an eSATA plug connector and a second inserting room for connecting an USB plug connector, the second inserting room having a nonoverlapping space relative to the first inserting room. The detecting switch includes a first detecting terminal that extends into the nonoverlapping space.
