Abstract

The invention provides a master-slave type socket system which is provided with at least one master socket and at least one slave socket. When an electric appliance product inserted and connected in the master socket reaches the enough current, the slave socket can be connected, thus the other electric appliance product inserted and connected in the slave socket can be also switched on. In addition, when the electric appliance product inserted and connected in the master socket is switched off or is in a park mode, the other electric appliance product inserted and connected in the slave socket can be also switched off.

Description

technical field [0001] The invention relates to a master-slave socket system, in particular to a socket system in which the slave socket can supply power only after the master socket starts to supply power. Background technique [0002] In recent years, users have paid more and more attention to the convenience, safety and economy of using electrical appliances, so the use of extension cords has also increased year by year. There are many types of extension cord sockets on the market, including single switch control extension cords and individual switch control extension cords. Wire. [0003] Please refer to figure 1 , is a schematic diagram of the appearance of the extension cord controlled by a single switch. The extension cord 1 controlled by a single switch (referred to as continuous control type) has a plug 10 , an extension cord 12 and a body 14 , wherein the body 14 is provided with a plurality of sockets 142 and a switch 144 . All the sockets 142 on the body 14 ar...
