Shield Case Cover Structure for Thin Camera Connector Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of miniaturizing a camera case while ensuring structural integrity and shielding for circuit boards and imaging elements, due to the need for a metal case and a resin component to hold a complex connector, results in increased thickness and device enlargement.
Innovation Solution
A case forming member with a conductive shield connector that combines a metal plate-like shield portion and a resin housing, where the resin portion has a larger thickness than the metal portion, allowing for reduced overall thickness and enhanced rigidity without compromising conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a metal member and resin member are united to form a covering portion, then the connector can be held securely, but the thickness of the covering portion increases and the entire device is enlarged
Solution Approach 1:
The patent merges the metal shield portion and resin exterior portion into a single integrated covering portion that simultaneously provides shielding, connector support, and aesthetic functions. This eliminates the need for separate metal and resin components, reducing overall thickness while maintaining all necessary functions.
Solution Approach 2:
The covering portion uses a composite structure where a thin metal plate is combined with a resin layer in a single integrated component. This composite approach allows the metal to provide shielding with minimal thickness while the resin provides structural support and connector holding capabilities.
2Object-affected harmful factors
If a metal case is used to shield circuit board and imaging element, then shielding effectiveness is improved, but the device size increases
Solution Approach 1:
The patent employs thin metal plates as shield portions that provide effective electromagnetic shielding while occupying minimal space. These thin film structures maintain shielding effectiveness without adding significant volume to the device.
Solution Approach 2:
The metal shielding is applied locally only where electromagnetic interference protection is needed, rather than using thick metal throughout the entire device. The thin metal plates are strategically positioned to provide shielding at critical areas while minimizing overall device volume.

AI summary
A case forming member forms a shield case by being conductively mounted on an opening of a box-shaped accommodating member made of metal and is provided with a cover-side shield connector including a cover-side outer conductor and a cover for covering the opening. The cover is configured by uniting a plate-like electrically conductive member, which is made of metal and includes a plate-like shield portion fixable to the accommodating member to cover the opening and a connecting portion connected to the cover-side outer conductor, and a housing, which is made of synthetic resin and includes a holding portion for holding the cover-side shield connector and a plate-like exterior portion to be overlapped on an outer surface of the shield portion. A plate thickness of the exterior portion is larger than a plate thickness of the shield portion in a covering portion where the shield portion and the exterior portion overlap.
