Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Referring to fig. 1 and fig. 2, the present embodiment provides a USB charging power distribution box, which includes a box body, a main circuit breaker 100, a

ground line bank

200, 4 paths of DC24V output power 300, and 16 paths of DC24V output connection terminals 400 are disposed on a rear panel of the box body, the main circuit breaker 100 is a circuit breaker of type NXBLE-32/C101P + N, and the ground line bank 200 is connected and conducted with a housing of the box body.

Referring to fig. 3, the input terminal of the main breaker QF is electrically connected to an external commercial power supply (AC220V power supply), the output terminals of the main breaker QF are electrically connected to the input terminals of the 4-way DC24V output power supplies, the output terminal of each way DC24V output power supply is electrically connected to the input terminals of the 4-way DC24V output connection terminals, and the output terminal of each way DC24V output connection terminal charges an external terminal device through a USB socket.

In this embodiment, the main circuit breaker 100 is an input interface introduced by an external mains power supply (AC220V power supply), and mainly plays a role in leakage, overload, and short-circuit protection; the DC24V output power supply 300 is used for converting an AC220V power supply into a DC24V output interface, and mainly converts alternating current 220V into direct current 24V to provide a power supply for charging a mobile phone; the ground wire row 200 is used for orderly, firmly, physically and orderly arranging and connecting a plurality of ground wires, has the function of protecting the ground wires by equipment, is tightly connected and conducted with the casing of the box body, leads the static electricity and the electric leakage part of the metal casing of the equipment output by each path to the ground, and simultaneously protects the equipment and the personal safety; the DC24V output wiring terminal 400 can adopt a porcelain insulator terminal block which has good insulating property, corrosion resistance and high temperature resistance;
