Power supply reverse plugging prevention device and server

Abstract

The invention discloses a power supply reverse plugging prevention device, which is characterized in that a baffle plate is positioned at a power supply plugging port, a limiting buckle is arranged onthe baffle plate, the limiting buckle is matched and clamped with a server shell, and when the limiting buckle is clamped with the shell, the baffle plate cannot rotate relative to the shell; an avoiding hole is formed in the baffle in a penetrating mode, a golden finger of the power module can penetrate through the avoiding hole from outside to inside and then makes contact with the limiting buckle after penetrating through the avoiding hole, acting force is applied to the limiting buckle, the limiting buckle is unlocked, the unlocked baffle can rotate relative to the shell; at the moment, the power module continues to be inserted inwards, the power module applies thrust to the baffle, and the power module can push the baffle to rotate. According to the power supply reverse plugging prevention device, the power supply module can be unlocked and inserted only when the golden finger is correctly inserted into the avoiding hole, so that unlocking cannot be performed during reverse insertion, the power supply module cannot be inserted, the anti-reverse-insertion judgment is completed at the initial stage of installing the power supply module, and the process of repeated insertion andextraction caused by reverse insertion is avoided.

Description

technical field [0001] The invention relates to the technical field of servers, and further relates to a power supply anti-reverse insertion device. In addition, the present invention also relates to a server. Background technique [0002] The power supply module dedicated to the server is a CRPS (Common redundant power supplies) power supply, and there is a gold finger on the back end of the power module for inserting into the server. [0003] The shape of the existing power module is a cuboid, so it may be installed upside down during installation. If there is no structure to prevent reverse insertion at the rear, the connector on the power board or the golden finger on the power module may be damaged. [0004] At present, the general practice and patents are mostly to use the iron shell behind the power module to make grooves, such as Figure 1A As shown, it is a schematic diagram of a power module with an anti-reverse insertion structure in the prior art; a positioning ...

AI Technical Summary

Problems solved by technology

[0005] The current anti-reverse insertion structure can only work when the power module is inserted almost to the bottom. If the direction is reversed, the power module needs to be pulled out again, which is inconvenient to operate; and such a design will need to destroy the structure of the module’s iron shell, and the internal design of the module is also difficult. Need to match the groove to move the part position
