Micro Electronic Plug Connector Structural Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional micro electronic plug connectors are prone to deformation and damage due to lack of connection between top and bottom sides, leading to structural weakness and electromagnetic interference (EMI) issues during signal transmission.
Innovation Solution
A micro electronic plug connector design featuring a connecting portion that integrates the top and bottom lateral walls, enhancing structural strength and incorporating a metal shell with a protruding portion to absorb and ground electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the top side and bottom side between the two inserting windows are not connected, then the manufacturing process is simpler, but the housing is prone to deformation and damage when forced
Solution Approach 1:
The housing is divided into multiple sections: a first housing section with a first inserting window for USB 3.0 signals, and a second housing section with a second inserting window for USB 2.0 signals. These segmented sections are connected through a connecting structure, allowing each section to be manufactured separately while maintaining overall structural integrity when assembled.
2Device complexity
If the top side and bottom side between the two inserting windows are not connected, then the device complexity is reduced, but electromagnetic interference occurs between USB 3.0 and USB 2.0 terminals
Solution Approach 1:
A connecting structure acts as an intermediary element between the first housing section and second housing section. This connecting structure includes shielding terminals that serve as electromagnetic shields, blocking interference between the USB 3.0 terminals and USB 2.0 terminals while maintaining structural connection between the two housing sections.
3Reliability
If a connecting structure is added between the two inserting windows, then structural strength and EMI protection are improved, but the device complexity increases
Solution Approach 1:
The connecting structure serves multiple functions simultaneously: it provides mechanical connection between the first and second housing sections to prevent deformation, acts as a shield to block electromagnetic interference between USB 3.0 and USB 2.0 terminals, and maintains the overall structural integrity of the housing. This multi-functionality reduces the need for separate components.

AI summary
A micro electronic plug connector includes an insulation housing, a first terminals, a second terminals, a metal shell and a connecting portion. The insulation housing includes a base member, a first tongue plate and a second tongue plate. The first and second tongue plates are extended from one side of the base member. The first and second terminals are disposed at the first and second tongue plates, respectively. The metal shell encloses the insulation housing and includes top and bottom lateral walls arranged with each other to form first and second frame windows. The bottom lateral wall includes a protruding portion, which includes a top plane adjacent to the top lateral wall, disposed between the first and second frame windows. An interval is defined between the top lateral wall and the top plane for disposing the connecting portion.
