Technical Field

The present invention relates to a power distribution unit, and more particularly, to a power distribution unit for a cabinet.

Background

A PDU (Power Distribution Unit), which is a Power Distribution socket for a cabinet, is a product designed to provide Power Distribution for electrical equipment installed in the cabinet, has various series specifications of different functions, installation modes and different plug-in combinations, and can provide a suitable rack-mounted Power Distribution solution for different Power environments. Due to the application of the PDU, the power supply in the cabinet can be distributed more orderly, reliably, safely, professionally and attractively, and the maintenance of the power supply in the cabinet is more convenient and reliable; the structure of the specific PDU can refer to a power distribution unit and a cabinet of Chinese utility model with the patent number ZL201821130233.3 (with the publication number CN208581429U), wherein the power distribution unit comprises a power distribution unit body, a lighting switch and at least one lighting lamp, the lighting lamp is positioned outside the power distribution unit body, and the lighting lamp is electrically connected with a power line in the power distribution unit body; the lighting switch is used for controlling the opening or closing of the lighting lamp, wherein three groups of power distribution jacks are arranged on a panel of the power distribution unit body, each group of power distribution jacks comprises four power distribution jacks, an external power plug can be plugged into the power distribution jacks to be electrically connected, the external power plug is frequently plugged, the power distribution jacks are easily enabled to generate higher failure rate, and the lighting lamp electrically connected with a power line in the power distribution unit body also has higher failure rate.

However, the PDU modules used in the market do not support hot-plug function, i.e. hot-plug, which allows a user to take out and replace damaged components such as a hard disk, a power supply, or a board card without shutting down the system or cutting off the power supply, thereby improving the timely recovery capability, expansibility, flexibility, etc. of the system against disasters, for example, some high-end application-oriented disk mirroring systems can provide the hot-plug function of a disk. Hot plugging was first introduced in the server area and was proposed to improve server ease of use.

The computer used by people at ordinary times generally has a USB interface, and the USB interface can realize hot plug. If the hot plug function is not available, even if the damage of the disk does not cause the loss of data, the user still needs to temporarily shut down the system so as to replace the hard disk. In case of power-on use, the power indicator lamp used on the market must first power off the whole system and then replace the power indicator lamp when the power indicator lamp fails during use, so that inconvenience is brought to users.
