Multi-Stage Alignment Guidepin for Server Connector Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The insertion and removal of servers in computer server racks often require direct force application, leading to bent connector pins due to non-parallel force application, which can cause damage to both the server and the connector.
Innovation Solution
The use of guidepins with distinct pre-alignment, alignment, and release portions on the connecting module and mounting plate ensures precise alignment and connection without binding, preventing damage by guiding the server into place through a blind-mate connection mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct force is applied to the server for insertion or removal, then the connection can be established, but the connector pins may bend due to non-parallel force application
Solution Approach 1:
The guidepin acts as an intermediary component between the server and the mounting plate. It provides a dedicated alignment pathway that guides the server into proper alignment with the connector, allowing force to be applied to the server body rather than directly to the connector pins. The guidepin's pre-alignment portion enters the aperture first to establish alignment, followed by the alignment portion that contacts the mounting plate surface, ensuring parallel force application throughout the insertion process.
2Ease of operation
If force is applied in a direction non-parallel to the connector, then the server can be inserted, but the connector pins are bent
Solution Approach 1:
The guidepin performs preliminary alignment actions before the actual connection is made. The pre-alignment portion with its larger diameter enters the aperture first to establish gross alignment, then the alignment portion with its smaller diameter provides fine alignment by contacting the mounting plate surface. This preliminary alignment ensures that when force is applied to insert the server, the connector pins are already properly positioned and will not bend.
3Reliability
If exact initial alignment is required for connection, then connector pin damage is prevented, but the operation becomes more difficult
Solution Approach 1:
The guidepin is segmented into distinct functional portions: the pre-alignment portion with a first diameter for entering and establishing gross alignment, and the alignment portion with a second, smaller diameter for providing fine alignment by contacting the mounting plate surface. This segmentation allows each portion to perform its specific alignment function, making the overall alignment process easier while ensuring precise final positioning that protects the connector pins.

AI summary
An alignment guidepin comprises a pre-alignment portion, an alignment portion, and a release portion. The pre-alignment portion provides gross alignment for a connection between a connecting module of a server and a connector of a computer server chassis. The alignment portion is connected to the pre-alignment portion having a first diameter to allow a high precision alignment for the connection between the connecting module and the connector. The release portion is connected to the alignment portion having a second diameter different than the first diameter to allow the connecting module and the connector to guide the connection.
