Rotatable Receptacle Structure for Slim Housing and EMI Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in slimming down their housing due to the mounting thickness of connection sockets such as receptacles, and there is a need for improved shielding and grounding solutions to enhance signal transmission and reduce electromagnetic interference (EMI) and electrostatic discharge (ESD) shielding.
Innovation Solution
A receptacle structure with a rotatable door cover that includes a metal member and a metal member that includes a rotatable door cover that includes a first metal member connected to a printed circuit board, a second metal member and a third metal member that is rotatable and provides grounding and electromagnetic interference (EMI) shielding, and a rotatable door cover that allows for easy automatic optical inspection and manual soldering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connection socket such as a receptacle is mounted in the electronic device, then electrical connection to external device is enabled, but the housing thickness increases making it difficult to slim down
Solution Approach 1:
The receptacle is nested within the rotatable door cover structure, where the door cover houses the receptacle assembly. This nested arrangement allows the connection socket to be integrated into the door cover's internal space rather than requiring additional external thickness, enabling slim housing design while maintaining electrical connection capability.
Solution Approach 2:
The door cover is designed to be rotatable, transitioning between open and closed positions. This dynamic structure allows the receptacle to be accessible when needed while maintaining a compact closed profile, solving the contradiction between connection accessibility and housing thickness.
2Ease of operation
If conventional receptacle structure is used, then connection function is provided, but grounding and EMI shielding are insufficient
Solution Approach 1:
The door cover is constructed using a composite structure combining metal members with grounding capabilities and EMI shielding properties. The metal door cover itself acts as a shielding barrier, while integrated grounding contacts provide electrical grounding, creating a composite solution that addresses both connection function and electromagnetic protection.
Solution Approach 2:
The grounding function and EMI shielding function are merged into the door cover structure itself. The metal door cover serves dual purposes: providing mechanical protection/housing for the receptacle and simultaneously acting as an EMI shield and grounding element, eliminating the need for separate shielding components.
3Object-affected harmful factors
If integrated receptacle structure is used, then grounding and EMI shielding are improved, but manufacturing complexity increases
Solution Approach 1:
The receptacle assembly is segmented into distinct components: the door cover, the receptacle body, and grounding contacts. This segmentation allows each component to be manufactured separately using appropriate processes, then assembled together, reducing overall manufacturing complexity while maintaining the integrated grounding and shielding functions.
