Abstract
The utility model provides an adjustable power socket possessing the main/auxiliary function. The purpose of the adjustable power socket possessing the main/auxiliary function is to solve the problems that a conventional socket can not be used correlatively, and the starting threshold of an auxiliary socket can not be adjusted. In an insulating housing, a 220V power frequency power supply is introduced, and the 220V power frequency power supply is connected in series with a primary of a current transformer T1 on a live wire, and then is output to a main socket. A secondary of the current transformer T1 is connected in parallel with a silicon bridge D1. An output terminal of the silicon bridge D1 is connected in parallel with a capacitor C1. An output low voltage terminal of the silicon bridge D1 is connected in series with an adjustable R1, and then is connected in parallel with a voltage stabilizing diode D2 and a light current control coil of a relay J1 with a high voltage terminal. A 220V power frequency power supply line is introduced between the current transformer T1 and the main socket.
