Problems solved by technology

General VPX power supply boards support hot swapping. When the board is plugged into the AC power supply, the power-on time of the circuit board in the power supply board is short, and a surge current will be generated, which is easy to cause damage to the circuit board in the board card. However, the existing In order to facilitate the user to remove and insert the VPX power board, it is usually necessary to use a puller to remove the board from the slot, and the puller only helps the user to pull out the board, and cannot prevent the surge when plugging in the power supply Damage caused by current to the circuit board inside the power board

Abstract

The invention discloses a VPX power supply. The VPX power supply comprises a power supply board card and a plugging assistant device fixed at the upper end of the power supply board card, wherein the plugging assistant device comprises a microswitch and controls on-off of the microswitch so as to control working state of the VPX power supply. The invention further discloses a hot-plugging realizing method of the VPX power supply. Surge current produced when the VPX power supply is plugged is reduced, power-on time of the power supply is prolonged, flash spark caused by high impact current when the power supply is plugged is avoided, the VPX power supply stops working immediately when the VPX power supply is pulled out, and the VPX power supply is protected.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a VPX power supply and a method for realizing hot plugging thereof. Background technique [0002] The micro switch is a contact mechanism with a small contact interval and a quick action mechanism, which performs a switching action with a specified stroke and a specified force. It is covered with a casing and has a drive rod on the outside. Small, hence the name micro switch, also called sensitive switch. [0003] Hot-plug technology has been widely used in some plug-and-play devices, which allows users to directly plug in or pull out devices without shutting down the system or cutting off the power supply, which provides convenience for users to use peripheral devices. General VPX power supply boards support hot swapping. When the board is plugged into the AC power supply, the power-on time of the circuit board in the power supply board is short, and a surge current will...
