DIMM Connector Baffle Snap-Fit Assembly Without PCB Mount Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plate covers for DIMM cards in servers are cumbersome to install and remove due to the need for bolts or screws, and they require mount holes on the circuit board, limiting available space for circuits and traces.
Innovation Solution
A connector assembly with a connector and baffle that uses engagement structures to securely attach the baffle to the connector without tools, allowing for easy installation and avoiding the need for mount holes on the circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plate cover is fixed to the circuit board via bolts or screws, then the plate cover can protect DIMM cards from contacting or being hit by nearby components, but the installation and removal of the plate cover involve troublesome processes requiring additional hand tools
Solution Approach 1:
The patent replaces the traditional mechanical fastening system (bolts or screws requiring hand tools) with an elastic latch mechanism that provides snap-fit engagement. The elastic latch can be deflected to release the plate cover and automatically returns to its original position to secure the cover, eliminating the need for additional hand tools while maintaining protective function.
2Reliability
If a plate cover is fixed to the circuit board via bolts or screws, then the plate cover can protect DIMM cards, but the circuit board needs to additionally form mount holes which limits the available area on the circuit board for circuits and traces
Solution Approach 1:
The patent merges the plate cover fixation function with the existing connector structure by integrating the elastic latch into the connector housing. This eliminates the need for separate mount holes on the circuit board, as the connector itself provides the mounting interface, thereby preserving valuable circuit board area for circuits and traces while maintaining plate cover protection.
3Reliability
If the plate cover is installed using additional hand tools and mount holes, then secure fixation is achieved, but the installation process becomes complex and time-consuming
Solution Approach 1:
The patent replaces complex mechanical fastening operations with a simple snap-fit mechanism operated by hand. The elastic latch can be easily deflected to release the plate cover and automatically returns to secure it, enabling rapid installation and removal without tools, thereby significantly improving assembling efficiency while maintaining secure fixation.
Solution Approach 2:
The elastic latch mechanism is self-actuating - when the plate cover is installed, the latch automatically returns to its original position through elastic recovery, securing the cover without requiring manual intervention or additional fastening steps. This self-service mechanism simplifies the installation process and improves productivity.
