[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 7 As shown:

[0028] A temperature element housing 2 includes a temperature measuring element 1 and a housing 2. A terminal block 11 is provided inside the housing 2, and the terminal block 11 is electrically connected to the temperature measuring element 1. A cover 5 is threadedly connected to the upper opening of the housing 2. A lead terminal 3 communicating with the interior of the housing 2 is provided on the outer side of the housing 2. A wire nut 4 through which a power line passes is threadedly connected to the open end of the lead terminal 3. The housing 2 and the lead terminal 3 are composed of two symmetrical and detachable parts. A plurality of firmly connected snap-fitting parts are fixedly connected to the inner side of the housing 2. A sealing ring 9 is fixedly connected to the outer side of the bottom end of the cover 5.

[0029] The engaging portion includes a male engaging end 21 and a female engaging end 22 . The male engaging end 21 and the female engaging end 22 in the same engaging portion are fixedly connected in different housings 2 .

[0030] In this embodiment, the housing 2 and the lead terminal 3 are symmetrically removable. Therefore, interference during wiring is minimized, and there is no problem of screws falling into the conical gap between the interior of the housing 2 and the bottom of the terminal block 11, which would make it difficult to remove the screws. Since the housing 2 is a removable split structure, it is more convenient to fix the sealing ring 9 to the cover 5. However, it should be noted that when the sealing ring 9 moves with the cover 5, the sealing ring 9 does not contact the threads of the housing 2.

[0031] The cooperation between the male engaging end 21 and the female engaging end 22 can improve the structural strength of the housing 2 when assembled, and avoid misalignment at the joint of the housing 2 when subjected to external force.

[0032] Further,

[0033] In an optional embodiment, a support seat 6 is fixedly connected to the outer side of one end of the temperature measuring element 1, the support seat 6 is located at the bottom of the outer shell 2, the top of the support seat 6 is fixedly connected to a limiting slider 62, and the bottom of the outer shell 2 is provided with a slide groove 23 that matches the limiting slider 62.

[0034] In this embodiment, through the cooperation between the limiting slider 62 and the sliding groove 23, it can be achieved that when the shell 2 is assembled, the shell 2 and the support base 6 will not be separated, thereby ensuring the connection stability of the shell 2.

[0035] In an optional embodiment, the male engaging end 21 and the female engaging end 22 are both arc-shaped.

[0036] In this embodiment, the arc-shaped setting of the male snap-fit ​​end 21 and the female snap-fit ​​end 22 can ensure that when the shell 2 is separated, it can only slide along the arc surface of the male snap-fit ​​end 21 and the female snap-fit ​​end 22. If the two parts of the shell 2 are separated horizontally, the separation of the two parts of the shell 2 will be restricted by the arc shape of the male snap-fit ​​end 21 and the female snap-fit ​​end 22, thereby improving the structural strength of the shell 2 when it is assembled.

[0037] In an optional embodiment, a lower arc surface 24 is provided on the top of the housing 2 , and an upper arc surface 61 matching with the lower arc surface 24 is provided on the top of the support seat 6 .

[0038] In this embodiment, the setting of the lower arc surface 24 and the upper arc surface 61 can ensure that when the shell 2 is separated, it can only slide along the arc surfaces of the lower arc surface 24 and the upper arc surface 61. If the two parts of the shell 2 are separated horizontally, the separation of the two parts of the shell 2 will be restricted by the arc structure of the lower arc surface 24 and the upper arc surface 61, thereby improving the structural strength of the shell 2 when it is assembled.

[0039] In an optional embodiment, the arc-shaped features of several male and female engaging ends 21, 22, the slide groove 23, the limiting slider 62, the lower arc surface 24, and the upper arc surface 61 are jointly extended around an axis. This arrangement can realize the disassembly of the shell 2.

[0040] In an optional embodiment, the rotation axes of several male engaging ends 21 and female engaging ends 22, the slide groove 23, the limiting slider 62, the lower arc surface 24, and the upper arc surface 61 are located below the shell 2. After the cover 5 is removed, the two parts of the shell 2 can be separated by moving along an arc trajectory, thereby improving the disassembly efficiency and at the same time improving the structural strength during connection.

[0041] In an optional embodiment, a limiting sleeve 41 facing the housing 2 is provided at the outer edge of the wire nut 4 , and the inner wall surface of the limiting sleeve 41 contacts the outer end surface of the lead terminal 3 .

[0042] In this embodiment, the limiting sleeve 41 can limit the structure of the lead terminal 3, thereby improving the overall structural strength and stability when the housing 2 is assembled.

[0043] In an optional embodiment, the opening distance between the limiting sleeve 41 and the wire nut 4 gradually decreases in the direction from the housing 2 to the lead terminal 3 .

[0044] In this embodiment, this arrangement can gradually increase the squeezing force applied to the lead end 3 when the wire nut 4 is gradually tightened.

[0045] In an optional embodiment, a sealing gasket 8 is provided at the joint of the two shells 2. The provision of the gasket can improve the sealing performance when the shells 2 are combined. The sealing gasket 8 can be directly fixed to any one shell 2 or clamped and fixed by the two shells 2.

[0046] In an optional embodiment, a sheath 7 is provided on the end of the housing 2 having the same outer diameter as the support base 6 and on the outer side of the support base 6 .

[0047] In this embodiment: the sheath 7 can further improve the connection stability between the outer shell 2 and the support seat 6, avoid dislocation, and at the same time improve the sealing of the joint between the outer shell 2 and the support seat 6. Therefore, a sealing layer can be provided on the inner wall of the sheath 7, such as a cylindrical rubber ring. The connection stability between the sheath 7 and the support seat 6 and the outer shell 2 is achieved through the contact friction between them. The sheath 7 can be completely separated from the support seat 6 and the outer shell 2 only when it is moved with force.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
