Riser Card and GPU Tray Interlock for Connector Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of preventing damage to connectors between a display card and a riser card when the riser card is removed from a server chassis before the display card, due to their different mounting directions.
Innovation Solution
Incorporating a restricting structure that engages the riser card assembly's handle with the display card assembly's tray to prevent the riser card from being removed before the display card, using engagement slots and hooks to maintain alignment and prevent sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display card and riser card are mounted in different directions to improve space utilization, then space utilization is improved, but the risk of connector damage increases when removal sequence is incorrect
Solution Approach 1:
The patent introduces a restricting structure as an intermediary mechanism between the display card assembly and riser card assembly. This structure includes a restricting component on the display card assembly that engages with a restricting groove on the riser card assembly, preventing the riser card from being removed before the display card. This mediator ensures proper removal sequence without affecting the different mounting directions, thus resolving the contradiction between space utilization and connector protection.
2Ease of operation
If the riser card is designed to be removable independently for maintenance, then ease of operation is improved, but connector damage occurs when removed before the display card
Solution Approach 1:
The restricting structure employs a dynamic engagement mechanism where the restricting component can freely move along the restricting groove during installation, but becomes locked in position when the display card is removed. This dynamic behavior allows the riser card to be accessible for maintenance while automatically preventing premature removal that would cause connector damage. The structure transitions from a constrained state during installation to a permissive state during maintenance.

AI summary
An electronic assembly and a chassis, where the electronic assembly includes chassis, riser card assembly and display card assembly. The riser card assembly includes bracket and riser card. The bracket includes main body, handle and first restricting structure. A side of the handle is pivotally connected to the main body. The first restricting structure is located on the handle. The main body is slidably disposed on the chassis. The display card assembly includes tray, display card and second restricting structure. The first restricting structure is located on the tray. The tray is slidably disposed on the chassis. When the tray is assembled to the chassis, the first restricting structure is engaged with the second restricting structure to prevent the handle from being pivoted relative to the main body, thereby preventing the handle from forcing the main body to slide relative to the chassis.
