Multi-Point Plug-In Connector Screening Sheet Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug-in connectors of great overall height face instability issues due to the fixing arrangement of screening sheets, which can impair the screening effect and lead to soldered connection failures when repeatedly plugged and unpluged.
Innovation Solution
The use of at least two rows of snap-in connections arranged one above the other provides a strong fixing mechanism for the screening sheets on the multipoint pin connector element, relieving the soldered connections and enhancing stability, with hook-like projections and receiving pockets ensuring secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the overall height of the plug-in connector is increased to accommodate taller electronic components, then the connector can support greater component heights, but the screening sheet fixing arrangement becomes unstable and may impair the screening effect
Solution Approach 1:
The screening sheet fixing mechanism is segmented into multiple rows of snap-in connections distributed along the height of the connector. This segmentation allows the fixing force to be distributed across multiple attachment points, maintaining stability even as the overall connector height increases. The screening sheet is thus securely attached at multiple levels rather than relying on a single fixing arrangement.
2Length of stationary object
If the length of the multipoint pin connector element is increased to achieve greater overall height, then the connector can accommodate taller devices, but the screening sheet fixing arrangement leads to instabilities
Solution Approach 1:
The screening sheet is preliminarily attached to the multipoint pin connector element through multiple rows of snap-in connections before the connector assembly is installed on the printed-circuit board. This preliminary attachment ensures that the screening sheet is already securely fixed and positioned correctly, preventing instabilities that would otherwise occur in tall connector assemblies during installation and operation.
3Ease of manufacture
If single-row snap-in connections are used to fix the screening sheet, then the manufacturing process remains simple, but the soldered connections on the printed-circuit board are not sufficiently relieved and may fail under repeated plugging
Solution Approach 1:
The snap-in connections are segmented into multiple rows along the height of the connector element. This segmentation distributes the mechanical stress and attachment force across multiple points, effectively relieving the soldered connections on the printed-circuit board from excessive stress. The multi-row arrangement maintains manufacturing simplicity while significantly improving the reliability of soldered connections under repeated plugging operations.
