Description

An isolated automatic safety socket

technical field

The present invention relates to the field of plug sockets, in particular to an isolated automatic safety socket. the

Background technique

Generally, the plugs of household appliances or other electrical equipment do not have switches. When the plugs are powered on when the appliances are not in use, the energy-consuming devices inside the appliances will still be at a static operating point, which will waste electricity and is not very safe. the

Another example is a plug with a switch disclosed in the utility model patent application whose publication number is CN 102044807 A. It includes a plug seat and a terminal on the plug seat. A switch device is installed on the end of the plug seat away from the end. The power line is connected to the switch device and then connected to the terminal. connect. When the electric appliance is used up, there is no need to unplug the plug holder, because there is a rotatable switch at the rear end of the plug holder, it is in the open state when it is parallel to the plug holder, and it is in the open circuit state when it is vertical. Though this utility model can play the effect of cutting off the circuit, still there is safety problem in this direct plug when running into unstable voltage. the

As a preference, the undervoltage armature is arranged in parallel between the protection switch and the conductive plug. the

As a preference, the power switch is arranged in series between the protection switch and the terminal.

As a preference, the power switch is a self-locking switch. the

As a preference, the wall thickness of the insulating housing is 2mm~3mm. the

In summary, the present invention has the following advantages:

1. In the present invention, a safety protection device for disconnecting the circuit during undervoltage and short circuit is provided between the conductive plug and the terminal post. In this way, it can play a protective role when the circuit is unstable, and even if a dangerous overcurrent phenomenon occurs when the power switch is pressed, the circuit will be automatically disconnected to play a protective role.

2. In the present invention, the wall thickness of the insulating shell is preferably 2mm~3mm. Such a thick insulating wall can effectively prevent the voltage fluctuation of 198V~298V from penetrating through the insulating shell of the plug and causing harm to the human body. the
