Connector Housing Ring Structure for EMI Shielding and Compact Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic device connectors are bulky, heavy, and complex to assemble, leading to increased manufacturing costs and electromagnetic interference issues due to the need for additional shielding structures.
Innovation Solution
A housing with a connection ring that encloses a shielding space for the connector, allowing for simplified installation and reduced weight and volume, while providing electromagnetic shielding without additional shielding structures on the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a boss structure is disposed on the housing to install the connector, then the connector can be firmly installed, but the weight and volume of the housing increase
Solution Approach 1:
The patent merges the boss structure with the housing body by integrating the connector installation function directly into the housing wall. The connector is installed through a through-hole in the housing wall without requiring a separate boss structure, thereby eliminating the additional weight and volume that a boss structure would add while maintaining secure connector installation.
2Reliability
If a flange structure is disposed on the connector outer housing for screw installation, then the connector can be firmly fixed, but the boss structure size increases
Solution Approach 1:
The patent eliminates the flange structure on the connector by integrating the fixation function into the housing wall itself. The housing wall provides structural support and fixation points directly, allowing the connector to be securely installed without requiring additional flange structures that would increase the boss structure volume.
3Object-affected harmful factors
If a metallic shielding case is added between the outer housing and inner housing, then electromagnetic interference is prevented, but manufacturing costs increase and shielding continuity is not ensured
Solution Approach 1:
The patent extracts the shielding function from the traditional metallic shielding case and relocates it to the housing wall structure itself. The housing wall is designed with conductive properties or shielding layers integrated into the wall, providing electromagnetic interference protection without requiring a separate shielding case, thereby reducing manufacturing complexity and cost while ensuring shielding continuity.
4Reliability
If screw installation is used to fix the connector, then the connector can be firmly attached, but the assembly process becomes complex and automated assembly is hindered
Solution Approach 1:
The patent replaces the screw-based mechanical fastening system with a simplified insertion or snap-fit mechanism. The connector is designed to be directly inserted into the housing wall through the through-hole and secured by integrated fixation features in the housing, eliminating the need for screws and complex assembly steps, thereby enabling automated assembly while maintaining firm attachment.

AI summary
This application provides a housing and an electronic device. The housing includes a main body and a connection ring. The main body has a via. The connection ring is disposed on one side of the main body and is connected to the via. The connection ring is configured to connect to a connector. The connection ring encloses shielding space for accommodating the connector. In the housing provided in this application, a boss structure used to install the connector does not need to be additionally disposed on the housing, so that a weight and a volume of the housing can be reduced. In addition, a technological process for assembling the connector and the housing can be further simplified. This reduces manufacturing costs, improves assembly efficiency, and facilitates automated assembly.
