Combined USB and MicroSD Connector Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for USB and MicroSD connectors require separate housings, leading to space inefficiencies on substrates like printed circuit boards, and lack integrated solutions for data storage and transfer capabilities.
Innovation Solution
A common housing combines a female USB connector and a female MicroSD card connector, with contact pins extending through the housing for connection to a substrate, allowing for symmetric orientation and optional shielding, enabling data transfer and storage while conserving space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate housings are used for USB connector and MicroSD connector, then each connector can be independently manufactured and assembled, but the space required on the substrate increases
Solution Approach 1:
The patent combines the USB connector and MicroSD connector into a single integrated housing structure. The housing includes a first cavity for the USB connector and a second cavity for the MicroSD connector, both formed within one unified component. This merging eliminates the need for separate housings and reduces the overall footprint on the substrate while maintaining independent manufacturability of the integrated unit.
2Area of stationary object
If a common housing is used for both connectors, then space on the substrate is conserved, but the device complexity increases
Solution Approach 1:
The integrated housing is divided into distinct cavities - a first cavity for the USB connector and a second cavity for the MicroSD connector. Each cavity is designed to accommodate its respective connector type with appropriate positioning and orientation. The contact pins for each connector extend through the housing wall at designated locations, allowing for modular assembly and simplified manufacturing of the integrated structure.
3Object-affected harmful factors
If shielding is added to the common housing, then electromagnetic interference protection is improved, but the manufacturing complexity increases
Solution Approach 1:
The housing can be constructed as a composite structure with an outer housing portion and an inner housing portion, where at least one portion incorporates shielding material. The shielding may be integrated directly into the housing walls or applied as a separate layer within the cavities. This composite approach provides electromagnetic interference protection while maintaining the benefits of the integrated connector design.

AI summary
A combination female USB connector and female MicroSD flash card connector include walls defining a housing in which a female USB connector and a female MicroSD flash card connector are disposed. Contact pins extend from contacts of the female USB connector and contacts of the female MicroSD flash card connector through at least one wall of the housing for connection to a printed circuit board. The walls include electromagnetic interference (EMI) shielding.
