PCB Shield with Bent Frame and Nested Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face interference issues between components mounted on printed circuit boards, necessitating a shield to prevent such interference, but conventional shields occupy excessive space.
Innovation Solution
A shield design comprising a shield frame with a column part and a bending part bent from its upper end, forming an angle less than 90 degrees, which reduces the shield's volume and allows for more efficient use of space by incorporating a shield cover that partially couples to the frame.

1Object-affected harmful factors
If a conventional shield is installed to surround electronic components, then interference between components is reduced, but the volume of the shield increases occupying excessive space
Solution Approach 1:
The shield cover is partially coupled to the shield frame, with the shield cover nested within the space defined by the shield frame. This nesting arrangement allows the shield to enclose electronic components effectively while minimizing the overall volume occupied by the shield structure itself.
Solution Approach 2:
The bending part is bent from the upper end portion of the column part at an angle smaller than 90 degrees, creating a three-dimensional configuration that reduces the horizontal footprint of the shield while maintaining its protective enclosure function. This angular bending optimizes space utilization by utilizing vertical and diagonal dimensions rather than only horizontal expansion.

AI summary
A shield is provided. The shield includes a shield frame surrounding an electronic component mounted on a printed circuit board and a shield cover partially coupled to the shield frame. The shield frame includes a column part mounted on the printed circuit board and a bending part bent from an upper end portion of the column part. An angle between both end portions of the bending part is smaller than about 90 degrees.
