Rotated Forklock Memory Module Connector for Mirror PCB Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-density system design, the placement of memory modules on both sides of a PCB is challenging due to conflicts between the forklocks of conventional connectors, preventing mirror-placed top and bottom memory modules.
Innovation Solution
The connector design includes a housing with elongated slots and forklocks that are rotated by a predetermined angle, such as 45 degrees, about the longitudinal direction of the housing, allowing for secure insertion into through holes on the PCB without conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If memory modules are placed on both sides of a PCB to increase system density, then the system density is improved, but the forklocks of conventional connectors conflict with each other preventing mirror placement
Solution Approach 1:
The forklocks are rotated by a predetermined angle (e.g., 45 degrees) relative to the longitudinal direction of the housing, creating an asymmetric configuration that eliminates conflicts between top and bottom connectors, enabling mirror placement of memory modules on both sides of the PCB
2Adaptability or versatility
If forklocks are rotated by a predetermined angle to enable mirror placement, then the connector adaptability is improved, but the device complexity increases
Solution Approach 1:
The forklocks are rotated by a specific predetermined angle (e.g., 45 degrees) to change the geometric parameter of the connector configuration, enabling mirror placement while maintaining a simple and manufacturable design

AI summary
An electrical connector for connecting a circuit card to a substrate. The connector includes a housing and forklocks. The housing is in an elongated shape and includes a slot for accepting an edge of the circuit card. The forklocks are extended from a bottom surface of the housing on each end of the housing. The forklocks are inserted into through holes formed in the substrate to secure the housing to the substrate. The forklocks are rotated by a predetermined degree of angle (e.g. 45 degrees) about a longitudinal direction of the housing. The circuit card may be a memory module, such as a dual in-line memory module, and the substrate may be a printed circuit board. The circuit card may be a daughter board and the substrate may be a mother board.
