Description

Technical Field

[0001] This utility model relates to the field of server hardware hardening technology, specifically to a PCIe daughter card hardening device using a Riser adapter card. Background Technology

[0002] In the vibration and shock tests of the national military standard GJB150A, traditional PCIe daughter cards are fixed only by a single screw at the front end baffle. After passing through the Riser card, a multi-level gold finger / connector series structure is formed, consisting of "motherboard → Riser card → PCIe daughter card → optical module / RJ45 Gigabit → fiber optic connector, etc." Mechanical vibration can easily cause micron-level displacement, leading to increased contact resistance and daughter card malfunction. The general PCIe specification does not consider ruggedized scenarios. For each additional stage in the transition process, signal integrity decreases by approximately 3dB, and the existing fixing method cannot suppress the relative movement between the transition layers.

[0003] Current hardening solutions mostly employ the method of encapsulating the entire PCIe daughter card or integrating the daughter card into the motherboard. This approach has drawbacks such as poor maintainability (replacing the daughter card requires damaging the encapsulation), low compatibility (only compatible with specific models), and high hardware costs (integrated motherboards require additional daughter card circuitry design).
