[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] Reference below Figures 1 to 4 A shell for encapsulating a temperature protector according to an embodiment of the utility model is described, comprising a shell 1, a temperature protector 4 and a wire 3, wherein the temperature protector 4 is placed in the shell 1, the temperature protector 4 is connected to the wire 3 and the wire 3 extends outside the shell 1, and an injection port 101 is provided on the front surface of the shell 1, the injection port 101 is filled with a silicone layer 2, and the silicone layer 2 seals the bottom of the temperature protector 4.

[0022] The structure is filled with a silicone layer 2 through the injection port 101, and the injection port 101 is convenient for filling silicone; in addition, the silicone layer 2 seals the bottom of the temperature protector 4 to achieve an isolation effect, improve safety and prevent arc damage to the wire. When the temperature protector 4 senses that the temperature reaches a specified value, the movable spring of the temperature protector 4 separates, an arc is generated, and when the arc reaches the silicone layer 2, it cannot contact the surface of the wire 3, thereby achieving a protective effect.

[0023] The conductor 3 of the present structure is provided with a copper wire core 301 , and the silicone layer 2 seals the surface of the copper wire core 301 . The silicone layer 2 plays a role in protecting the copper wire core 301 .

[0024] The silicone layer 2 of this structure wraps the outer surface of the upper end of the wire 3. The silicone layer 2 can also fix the position of the wire 3; the wire 3 is located at the injection port 101 according to actual needs, which is convenient for selecting a better position for the wire 3 in an actual installation environment.

[0025] The silicone layer 2 of this structure extends to the bottom surface of the housing 1. The temperature protector 4 prevents the arc from being discharged from the bottom surface of the silicone layer 2. The copper wire core 301 of this structure is L-shaped, and a part of the silicone layer 2 extends to the bottom of the copper wire core 301.

[0026] The thickness of the copper wire core 301 in this structure is 1 cm to 2 cm, which improves the insulation effect.

[0027] The top of the shell 1 described in this structure is in an arc shape, which on the one hand increases the contact area between the shell 1 and the ambient temperature, and on the other hand reduces the inner cavity space 5 of the shell 1, further increasing the transmission speed between the temperature protector 4 and the ambient temperature, so that the temperature protector 4 can further accurately detect the temperature signal, thereby quickly feeding back the detected temperature signal to the electronic control, and the electronic control further implements circuit protection.

[0028] The shell 1 is a plastic shell or a metal shell. The use of a plastic shell can reduce production costs, and in order to increase the strength of the corresponding product of this embodiment, the shell 1 is a metal shell; of course, the shell 1 can be made of different materials according to the actual use environment, such as the shell 1 is made of ceramic material.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
