Electrical Connector Shielding Shell Abutting Arms Structural Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors lack a firm structural integration between the terminal module, insulative housing, and shielding shell, which can lead to instability and potential electrical interference.
Innovation Solution
The electrical connector incorporates a terminal module with an insulator, terminals, and a horizontal printed circuit board carrying magnetic components, along with a shielding shell that has abutting arms interference-fitted between the insulator and PCB, and restraining slots in the insulative housing to secure the terminal module, while also accommodating LEDs for enhanced stability and grounding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the terminal module is simply received by the insulative housing without additional support structures, then the device complexity is reduced, but the structural stability and firmness deteriorate
Solution Approach 1:
The support function is segmented between two distinct structures: the insulative housing provides front support through restraining slots, while the shielding shell provides rear support through abutting arms. This segmentation allows each component to contribute to structural stability without requiring one component to be overly complex
Solution Approach 2:
The shielding shell acts as an intermediary structure that not only provides electromagnetic shielding but also serves as a support element through its abutting arms. This mediator approach allows the shielding shell to fulfill dual functions: protection and structural support
2Object-affected harmful factors
If the shielding shell is added to enclose the insulative housing and PCB, then electrical interference is reduced, but the device complexity increases
Solution Approach 1:
The shielding shell is designed to perform multiple functions simultaneously: it provides electromagnetic shielding to reduce interference, acts as a structural support element through its abutting arms, and contributes to the overall firmness of the assembly. This multi-functionality reduces the need for separate components
Solution Approach 2:
The shielding function and structural support function are merged into a single component - the shielding shell. By integrating the support arms into the shielding shell structure, the patent combines what could have been separate functions into one unified component, reducing overall device complexity
