Delay power strip

Abstract

The invention relates to a delay power strip, which comprises a first switch (1), an indicating lamp part (2), a socket part (3) and a second switch (4), wherein the indicating lamp part (2) and the socket part (3) are connected in parallel between the first switch (1) and the second switch (4); the indicating lamp part (2) and the socket part (3) are connected with a high potential end through the first switch (1); the indicating lamp part (2) and the socket part (3) are connected with a low potential end through the second switch (4); and the socket part (3) comprises a plurality of socket modules which are connected in parallel. According to the delay power strip provided by the invention, each socket module is provided with a delay circuit, when the power strip is connected with a power supply and the switch is turned on, jacks of all the socket modules are respectively delayed to be connected with the power supply at different times, the jacks on the power strip are prevented frombeing simultaneously connected with the power supply, and the delay circuit comprises a comparator P, so that the delay precision can be improved; and high current caused by simultaneous operation ofmultiple sets of electric equipment on the power strip is avoided, and the power strip is safer to use.

Description

technical field [0001] The invention belongs to the field of smart home, and in particular relates to a delay plug-in. Background technique [0002] Nowadays, as an important part of smart home, smart electricity consumption has penetrated into people's lives. Whether it is in the working environment or at home, the shadow of smart home can be seen everywhere. The use of smart home will also lead to changes in power access, which will lead to the use of multi-functional plug strips, while using electrical appliances, it also avoids the lack of jacks. The plug-in strip is a multi-position socket with wires, commonly known as a plug-in board, a plug-in strip, and the scientific name is a wire extension component or an extension cord socket. The socket refers to a multi-position socket with a power cord and a plug that can be moved. More than one power plug can be connected, which not only saves space but also saves lines. [0003] Nowadays, the use of smart home has become ...

Problems solved by technology

[0004] However, when the switch is turned on for the plug-in strips currently used, all the sockets used are charged, and the electrical equipment plugged into the plug-in strip will be energized in an instant. It will cause the instantaneous current of the plug-in strip to be too large; or after a power outage, a sudden call comes in, but the plug-in strip is not turned off, and the plugged-in electrical equipment is powered on, which will also cause an instantaneous high current, which will cause damage to the plug-in strip, and even cause burn electrical equipment
