Triple Combo Electrical Connector for USB 2.0, 3.0 and eSATA
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrical connectors lack compatibility with multiple standards such as USB 2.0, USB 3.0, and eSATA, requiring separate connectors and complicating the transition and usage in devices.
Innovation Solution
A triple combo type electrical connector design featuring an insulating housing with specific contact arrangements and configurations that allow for compatibility with USB 2.0, USB 3.0, and eSATA protocols, utilizing a tongue portion with distinct mating faces and contact sections to accommodate different standards within a single mating port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a combo type connector is designed to accommodate multiple standards (USB 2.0, USB 3.0, eSATA), then compatibility and versatility are improved, but device complexity and structural design difficulty increase
Solution Approach 1:
The patent merges three separate connector functions (USB 2.0, USB 3.0, and eSATA) into a single integrated connector housing. The insulating housing contains all three sets of contacts (first contacts for USB 2.0, second contacts for USB 3.0, and third contacts for eSATA) arranged in a unified structure, allowing one connector to replace three separate connectors and achieve multi-standard compatibility.
Solution Approach 2:
The connector is designed as a universal interface that can accommodate multiple connection standards through its multi-functional contact arrangement. The housing and contact configuration enable the same physical connector to support USB 2.0, USB 3.0, and eSATA protocols, making the device universally compatible across different standards without requiring separate dedicated ports.

AI summary
An electrical connector includes an insulating housing and contacts, the insulating housing defines a mating cavity and a tongue portion in the cavity, the tongue portion defines a first and a second mating face. A set of first contacts each defines a first contacting section disposed on the first mating face and a leg portion. A set of second contacts each defines a first contacting section disposed on the first mating face and a second contacting section bending from the first contacting section to be in the second mating face, a leg portion and a retention section connecting with the first contacting section and a the leg portion. A set of third contacts each defines a contacting section disposed on the second mating face and a leg section. The contacting portions of the third contacts are disposed at two sides of the second contacting sections of the second contact.
