[0002] The amount of current that can continuously pass through an electrical circuit without causing the wire to overheat is called the safe carrying capacity or safe current. If the current flowing through the wire exceeds the safe carrying capacity, it is called wire overload. Generally, the maximum allowable operating temperature of the wire is 65 °C. During overload, the temperature exceeds this temperature, which will cause the insulation to age rapidly or even the circuit to catch fire. The overload protection device of the existing controller has poor automation effect and slow overload detection process, resulting in low current detection efficiency.

Each group of detection mechanisms 6 is clamped on the control circuit 2.

[0037] Generally, a control circuit 2 for signal transmission of the controller is installed through the inside of the controller housing 1. The detection mechanism 6 arranged inside the controller housing 1 can be clamped on various parts of the control circuit 2 to perform multi-point detection on the control circuit 2. The detected temperature signal is converted into an electrical signal through the detection line 5 and then detected and prompted by the four groups of detection lights 4 arranged on the top of the installation block 3.

[0038] The detection mechanism 6 includes a clamping ring 7. A clamping notch 8 is formed at the bottom of the clamping ring 7. The clamping ring 7 is connected to the control circuit 2 through the clamping notch 8. A heat-conducting layer 9 is arranged inside the clamping ring 7. A temperature detector 10 is installed inside the clamping ring 7. A detection head 11 is arranged at the bottom of the temperature detector 10. The detection head 11 runs through the clamping ring 7 and the heat-conducting layer 9 to the inside of the clamping ring 7.

[0039] The clamping ring 7 installed in the detection mechanism 6 can be clamped on the control circuit 2 at the clamping notch 8. The heat-conducting layer 9 arranged inside the clamping ring 7 can conduct the heat generated by the control circuit 2. The heat conducted by the heat-conducting layer 9 is detected for temperature through the detection head 11 arranged inside the clamping ring 7. The temperature detector 10 connected to the detection head 11 can receive the temperature change of the detection head 11. Finally, the temperature signal is transmitted by the temperature detector 10 and the detection line 5 to control the detection lights 4 arranged on the installation block 3 to light up for warning.

A contact block 17 is arranged inside the hollow channel 16. The hollow channel 16 arranged on the detection circuit 5 provides an installation space for the electric control telescopic rod 13. The electric control telescopic rod 13 jacks up the contact block 17 to make the contact block 17 move up and down inside the hollow channel 16.

[0042] Two groups of lamp control circuits 14 are arranged inside the mounting block 3. A contact point 15 is arranged between the two groups of lamp control circuits 14. The contact point 15 is cooperatively installed with the contact block 17. The contact block 17 is arranged between the two groups of lamp holes circuits. When the temperature detector 10 detects the temperature, the temperature sensor controller 12 can operate the electric telescopic rod. The contact block 17 is jacked up by the electric telescopic rod. The contact point 15 and the contact block 17 cooperate to connect the lamp control circuits 14 connected to the detection lamp 4 in series to light up the detection lamp 4 for warning.
