Combined RJ and MicroSD Connector Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to efficiently combine RJ connectors and MicroSD card connectors in a single housing on a PCB, leading to space inefficiencies and limited integration of data storage and networking capabilities.
Innovation Solution
A combined housing for a female RJ connector and a female MicroSD card connector with symmetrically oriented contact pins, allowing for various mounting configurations and optional shielding, along with an integrated circuit chip for data analysis and storage, enables space-saving integration on a PCB while providing both networking connectivity and data storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If separate RJ connector and MicroSD card connector are installed on PCB, then each connector can be individually optimized, but space on PCB is wasted
Solution Approach 1:
The patent combines an RJ connector and a MicroSD card connector into a single integrated housing structure. The common housing contains both connectors with their respective contact pins, allowing them to be mounted together on the PCB as one unit. This merging eliminates the need for separate mounting spaces and reduces overall PCB area occupation while maintaining individual functionality of each connector type.
Solution Approach 2:
The integrated housing serves multiple functions simultaneously: it provides mechanical support and mounting for both RJ and MicroSD card connectors, offers electromagnetic shielding for both connectors, and enables space-efficient PCB installation. The single housing structure performs what would traditionally require two separate connector assemblies, achieving multi-functionality in a unified design.
2Area of stationary object
If RJ connector and MicroSD card connector are integrated in common housing, then PCB space is saved, but manufacturing and assembly complexity increases
Solution Approach 1:
The patent integrates RJ and MicroSD card connectors within a single common housing, allowing them to be manufactured and assembled as one unit. This merging simplifies the overall manufacturing process by reducing the number of separate components that need to be procured, managed, and assembled on the PCB, despite the increased internal complexity of the housing design.
3Adaptability or versatility
If symmetric orientation of contact pins is used, then mounting flexibility is improved, but connector design complexity increases
Solution Approach 1:
The patent employs symmetric orientation of contact pins within the integrated housing, where the RJ connector and MicroSD card connector contact pins are arranged in mirror-image or balanced configurations. This symmetric arrangement provides mounting flexibility and adaptability to different PCB layouts, while the symmetry itself simplifies the design process by providing regular, predictable patterns that are easier to manufacture and assemble compared to asymmetric arrangements.

AI summary
A combination connector includes a number of walls defining a housing and a female RJ connector and a female flash card connector inside the housing. Contact pins extend from contacts of the female RJ connector and contacts of the female flash card connector through at least one wall of the housing for connection to a PCB. The walls include electromagnetic interference (EMI) shielding.
