Display Connector Fixing Part for EMI Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, such as LCDs, face issues during assembly where cables connected to the PCB can be separated, leading to defective devices, and electromagnetic interference (EMI) from the connector causes malfunctions.
Innovation Solution
A display device design featuring a cover member with a fixing part that elastically presses the connector to the PCB, including a protrusion and contact part, and optionally a gasket or elastic member to prevent separation and suppress EMI, combined with a fastening system using screws and concave-convex parts for enhanced stability and shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector is exposed through the cover member, then the cable connection is enabled, but the connector becomes vulnerable to separation and EMI interference
Solution Approach 1:
A fixing part is introduced as an intermediary component between the connector and the cover member. This fixing part includes a pressing portion that contacts the connector and a supporting portion that engages with the cover member, thereby mediating the connection and preventing connector separation while maintaining EMI shielding.
Solution Approach 2:
The fixing part is segmented into distinct functional portions: a pressing portion for contacting and securing the connector, and a supporting portion for engagement with the cover member. This segmentation allows each portion to optimize its specific function while working together as an integrated solution.
2Ease of operation
If the connector is exposed through the cover member, then the cable connection is enabled, but EMI from the connector causes malfunctions
Solution Approach 1:
The fixing part serves as an intermediary shielding structure between the connector and the external environment. By positioning the pressing portion in contact with the connector and the supporting portion engaged with the cover member, it creates a localized EMI barrier without compromising cable accessibility.
3Reliability
If a fixing structure is added to prevent connector separation, then connector stability is improved, but device complexity increases
Solution Approach 1:
The fixing part merges multiple functions into a single integrated component: it provides mechanical retention for the connector, maintains positioning accuracy, and offers EMI shielding. This consolidation prevents connector separation without significantly increasing overall device complexity.
Solution Approach 2:
The fixing part is designed as a multi-functional component that simultaneously achieves connector retention, positioning, and EMI protection. This universality allows a single element to address multiple concerns, thereby improving reliability without proportionally increasing structural complexity.

AI summary
A display device includes a panel assembly for forming an image, a printed circuit board (PCB) connected with the panel assembly and having a connector; a support member for supporting the panel assembly and having the PCB installed on a rear surface thereof, and a cover member combined with the support member, covering the PCB, and having an opening exposing the connector. A fixing part formed at the opening of the cover member fixes the connector to the PCB.
