Abstract

The invention provides a multifunctional power supply box, and relates to a safety protection technology of electric appliance loads. The multifunctional power supply box aims to solve the safety problems in an existing power supply power strip. A first power supply switch control element is a power supply main switch, wherein a power supply protective tube is connected to each live wire between the first power supply switch control element and a first power supply protective circuit in series; a power supply protective tube is connected to each live wire between a second power supply switch control element in power output circuits and a power supply output terminal in series; the power supply main switch, a branch switch and a standard charging terminal interface are arranged on a panel of a shell, a ventilation hole and an arc-shaped hole are formed in a rear baffle, and a socket is arranged inside the rear baffle. By means of the multifunctional power supply box, a main power supply and a branch power supply can be controlled safely and independently, and the main power supply and the branch power supply respectively have the overload and short circuit protection function, the lightning stroke resistance, surging resistance and current surge protection function, and the electromagnetic interference resistance protection function. The multifunctional power supply box is suitable for places such as families, enterprises, shopping malls and laboratories.

Description

technical field [0001] The invention relates to the safety protection technology of electric load. Background technique [0002] Power strips have a wide range of uses, whether it is household power strips, power strips for enterprises and institutions, or power strips for research and development experiments, etc., and there are many types and specifications. The disadvantages of the common double-row power strips are: 1. A plurality of power plugs are shared and inserted in one power inlet box, and there is only one main switch for control, and there is no independent power control switch for control. Some do not even have a master switch control; 2. The power distribution between the connected electrical loads is unbalanced and affects each other. Once one of the electrical loads fails, it will affect the normal operation of other electrical loads on the entire power strip. Use; 3. After all the electric load plugs are inserted, the lines are many and messy, occupy a lar...
