The connection section and the second connection section, and the load detection module is configured to have a maximum current value. When the load detection module detects that the current value of the power supply line is greater than the maximum current value set by the load detection module, the load The detecting module controls the protection switch to disconnect the electrical connection between the first connecting segment and the second connecting segment.

The extension line of the overload protection device, wherein the overload protection device is provided with a reset button, the reset button is electrically connected to the protection switch, and the reset button is used to control the protection switch to be electrically connected to the power line. The first connecting segment and the second connecting segment.

The above-mentioned extension line of the overload protection device, wherein the load detection module of the overload protection device is connected with a communication module, and the communication module wirelessly transmits the current value detected by the load detection module to the recorder.

The aforementioned extension cord with an overload protection device, wherein the recorder is a computer or a portable electronic product.

Referring to the first to third figures, it can be clearly seen from the figure that the creation system has a power cord 1 and an overload protection device 2, and the power cord 1 has a first connecting section 11 and a second connecting section 12, the first connection A plug 3 is connected to one end of the segment 11 , and the other end of the second connecting segment 12 is connected to the overload protection device 2 . The other end of the second connecting segment 12 is connected to the overload protection device 2 , and the overload protection device is connected to the overload protection device 2 . 2 has a body 21, the body 21 is provided with a reset button 25, and the body 21 is provided with a protection switch 23 and a load detection module 24, the protection switch 23 is electrically connected to the load detection module 24 and the power line 1 The first connection segment 11 and the second connection segment 12 are electrically connected to the protection switch 23, and the load detection module 24 is set to have a maximum current value 241.

With the above structure, the overload protection device 2 controls the electrical connection between the plug 3 and the socket 4, so that the overload protection device can be connected to different plugs and sockets according to requirements. When used, the user connects the required plugs 3 according to requirements. The first connecting section 11 is away from one end of the overload protection device 2, and the required socket 4 is connected to the second connecting section 12 away from one end of the overload protection device 2, and the external power source is connected by the plug 3 to make the power line 1 The first connecting segment 11 and the second connecting segment 12 are electrically connected. When the current value of the power cable 1 is less than the maximum current value 241 set by the load detecting module 24, the first connecting segment 11 of the power cable 1 is The second connecting section 12 is electrically connected to provide power for the electrical appliances plugged into the socket 4 to be activated. When the user plugs in the electrical appliance in the socket 4, the load detecting module 24 detects the power. The current value of the line 1 is greater than the maximum current value 241 set by the load detection module 24, and the load detection module 24 controls the protection switch 23 to disconnect the electrical connection between the first connection segment 11 and the second connection segment 12. In order to avoid the danger caused by electrical overload The user selects the protection switch 23 to electrically connect the first connection segment 11 and the second connection segment 12 of the power line 1 by using the reset button 25 after removing the electrical appliance causing the overload.

Please refer to the fourth figure. It can be clearly seen from the figure that in another embodiment of the present invention, the load detection module 24 of the overload protection device 2 is connected with the communication module 22, and when the load detection module 24 detects When the current value flowing to the power line 1 is greater than the maximum current value 241 set by the load detection module 24, the communication module 22 wirelessly transmits the current value detected by the load detection module 24 to the recorder 5. Wherein the recorder 5 is a computer or a portable electronic product.
