The temperature control switch 2 and the pins 3 are both arranged on the insulating bracket 1. The two pins 3 are respectively located on both sides of the temperature control switch 2. One of the pins 3 is connected to the live wire in the wire, and the other pin 3 is connected to the neutral wire in the wire. A heat conduction member 4 is respectively arranged between the temperature control switch 2 and the two pins 3.

[0032] When heat is generated between the pin 3 and the socket, the heat is transmitted to the temperature control switch 2 through the heat conduction element 4. If the temperature value rises to the set over-limit alarm temperature point, an alarm signal is sent to the external operating end, and the external operating end cuts off the power supply, thereby achieving a protective effect.

[0033] In this embodiment, the heat conducting member 4 is configured as a ceramic block. The main component of the ceramic block is beryllium oxide, which has a very high thermal conductivity, almost equal to that of copper and pure aluminum, and also has a very good thermal shock resistance.

[0034] In this embodiment, the pin 3 is made of copper, which has high thermal conductivity, and is convenient for quickly transferring the heat of the pin 3 to the heat conducting member 4 .

[0035] In this embodiment, a positioning block 5 is provided on the insulating support 1 , and the positioning block 5 is used to fix the heat conducting member 4 on the insulating support 1 .

[0036] In this embodiment, positioning holes 6 are provided on the heat conducting member 4 and the positioning block 5 , and the positioning holes 6 are used to ensure that the heat conducting member 4 does not move when the insulating bracket 1 is injection-molded.

[0037] In this embodiment, a through slot 7 is provided on the positioning block 5 , and one end of the temperature control switch 2 is arranged in the through slot 7 , so as to improve the stability of the temperature control switch 2 .

[0038] In this embodiment, a through hole 8 is provided on the positioning block 5 , and one end of the plug pin 3 passes through the through hole 8 , thereby improving the stability of the plug pin 3 .

[0039] In this embodiment, a plurality of protrusions 9 are disposed on the outside of the plug pin 3 , and the protrusions 9 are located between the plug pin 3 and the insulating support 1 , so as to improve the stability of the connection between the plug pin 3 and the insulating support 1 .

[0040] In this embodiment, the protrusions 9 are distributed in a ring shape, which further improves the stability of the connection between the pin 3 and the insulating bracket 1 .

[0041] In this embodiment, the insulating bracket 1 is made of plastic material, which is convenient for injection molding.

[0042] The working principle of a temperature control plug in the embodiment of the present application is as follows:

[0043] When heat is generated between the pin 3 and the socket, the heat is transmitted to the temperature control switch 2 through the heat conduction element 4. If the temperature value rises to the set over-limit alarm temperature point, an alarm signal is sent to the external operating end, and the external operating end cuts off the power supply, thereby achieving a protective effect.

[0044] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
