The temperature sensing element 1 has an element pin 11, the conductive element 2 has a connecting portion 21 used to fix and electrically connect with the element pin 11, and a switching portion 22 used to electrically connect with the electronic component 500.

[0031] In combination with the structure of the electronic component 500, it can be known that in the present application, the switching portion 22 is in contact with the gold finger 5111 of the electronic component 500.

[0032] To further facilitate the disassembly of the temperature sensing component 100 and the electronic element 500, in the embodiment, the adapter 22 is formed with a fixing structure 221 for mechanically fixing the electronic element 500, and the insulating base 3 is further provided with a limiting wall 31 arranged on one side of the adapter 22 to protect and limit the insertion of the adapter 22 and the electronic element 500.

[0033] As a preferred embodiment of the present application, the fixing structure 221 is arranged in the form of a bent elastic arm, and the limiting wall 31 is arranged opposite to the fixing structure 221, so that the butt joint part 51 of the electronic element 500 can be clamped and fixed between the elastic arm-shaped fixing structure 221 and the limiting wall 31.

[0034] Specifically, in combination with Figures 1 to 9 As shown in the figure, the conductive element 2 is a pair of sheet-shaped conductive terminals arranged at intervals and connected with a pair of element pins 11 of the temperature sensing element 1. Each conductive element 2 is formed with a fixed segment 23 fixed in the insulating base 3, and the connecting part 21 and the adapter 22 are reversely extended from both ends of the fixed segment 23.

[0035] In the embodiment, the conductive element 2 is inserted and fixed in the insulating base 3, and to ensure the stability of the fixation, the fixed segment 23 is formed with barb structures 231 protruding on both sides to interfere and fix with the insulating base 3.

[0036] The insulating base 3 has a base part 32 fixedly matched with the fixed segment 23, and a containing part 33 connected with the base part 32, and the limiting wall 31 is extended from one side of the base part 32 away from the containing part 33. Correspondingly, the connecting part 21 and the adapter 22 are located on both sides of the base part 32 and placed on the containing part 33 and the limiting wall 31, respectively.

[0037] The base part 32 is formed with a pair of mounting grooves 321 penetrating from front to back above the containing part 33 and the limiting wall 31, and the conductive element 2 is fixed to the insulating base 3 by penetrating through the mounting grooves 321 above the limiting wall 31. On the one hand, the insulating base 3 insulates the pair of conductive elements 2 from each other, and on the other hand, it cooperates with the conductive element 2 to realize the stable connection of the temperature sensing element 1 and the electronic element 500.

[0038] Among them, the fixed segment 23 is fixed in the mounting groove 321.

[0039] The accommodating part 33 is formed with an accommodating cavity 330 with one side opening, a bottom wall 331 formed at the bottom of the accommodating cavity 330, side walls 332 and end walls 333 extending from both sides and the end of the bottom wall 331 in the same direction, and the end wall 333 is opposite to the base 32; the accommodating cavity 330 is located between the side wall 332, the end wall 333, the bottom wall 331 and the base 32. The connecting part 21 protrudes into the accommodating cavity 330 from the fixed section 23, and the temperature sensing element 1 is accommodated in the accommodating cavity 330 and connected with the connecting part 21.

[0040] Further, the accommodating part 33 also has a supporting rib 334 protruding into the accommodating cavity 330 from the bottom wall 331, the supporting rib 334 is correspondingly arranged in pairs and spaced apart from the connecting part 21, and the connecting part 21 and the temperature sensing element 1 are both supported on the supporting rib 334.

[0041] In this embodiment, the connecting part 21 is in the form of a sheet and is fixedly connected to the element lead 11 of the temperature sensing element 1 by welding; of course, as another embodiment, the connecting part 21 can also be bent to form a clamping structure, and then the element lead 11 of the temperature sensing element 1 is clamped and fixedly connected by the clamping structure. Preferably, the temperature sensing assembly 100 further comprises an insulating glue (not shown) arranged in the accommodating cavity 330 and covering at least around the element lead 11 and the connecting part 21, which can not only ensure the stable connection between the temperature sensing element 1 and the conductive element 2, but also protect the connection part of the two.

[0042] In combination Figure 1 Figure 9 As shown, on the other side of the base 32 away from the accommodating part 33, the limiting wall 31 is in the form of a flat plate and is located on the same plane as the bottom wall 331. As described above, in this embodiment, the fixing structure 221 of the adapter 22 is in the form of a single elastic arm to clasp the connecting part 51 of the electronic element 500 together with the limiting wall 31.

[0043] Of course, as another preferred embodiment of the present application, the fixing structure 221 can also be directly bent into the form of a clamping arm, and then the clamping connection is formed between the fixing structure 221 and the electronic element 500 in the form of a clamping arm. The fixing structure 221 can also be bent to be perpendicular to the connecting part 51, and a perforation corresponding to the fixing structure 221 is arranged on the connecting part 51, and then the plug-in connection is formed.

[0044] Further, the limiting wall 31 is further provided with a protruding rib 311 between the two connecting portions 22 of the conductive sheet element 2, which is used to cooperate with the electronic element 500. Specifically, when the electronic element 500 is inserted, the two insertion tabs 511 of the electronic element 500 move along the two sides of the protruding rib 311, and the guide groove 512 between the two insertion tabs 511 cooperates with the protruding rib 311, thereby achieving insertion guidance and limiting the lateral movement of the electronic element 500.

[0045] In addition, the insulating base 3 in the embodiment further has a guide wall 34 extending from both sides of the limiting wall 31 towards the fixing structure side, and the opposite end of the guide wall 34 to the limiting wall 31 forms a first opening 35, and the adjacent end of the guide wall 34 and the limiting wall 31 forms a second opening 36 for the insertion of the electronic element 500.

[0046] As shown in Figures 5 to 9 , the guide wall 34 is provided with a guide structure 341 for guiding the insertion of the electronic element 500. In the embodiment, the guide structure 341 is a guide groove recessed from the inner wall surface of the guide wall 34, the bottom surface of the guide groove is located in the same plane as the surface of the limiting wall 31, and the end of the guide groove away from the base 31 penetrates the second opening 36, thereby enabling the guide protrusion 513 of the connecting portion 51 of the electronic element 500 to extend into the guide groove and move along the guide groove towards the base 31 when the electronic element 500 is inserted. Thus, the guide groove not only enables smooth guidance of the insertion of the electronic element 500, but also enables limiting of the electronic element 500 in the up-down direction.

[0047] Preferably, in the embodiment, as shown in Figures 1 to 5 , the temperature sensing assembly 100 further comprises a cover 4 covering the first opening 35.

[0048] As shown in Figures 1 to 9 , the cover 4 has a cover plate portion 41 arranged at the first opening 35, and a positioning leg 42 extending from the cover plate portion 41 towards the limiting wall 31, and the positioning leg 42 extends downwardly to the limiting wall 31 to cooperate with the positioning notch 514 on the electronic element 500.

[0049] In the embodiment, the positioning leg 42 extends from both sides of the cover plate portion 41, and when the cover 4 is closed, the positioning leg 42 is located inside the guide wall 34 and extends downwardly through the guide structure 341 to simultaneously cooperate with the positioning notches 514 on both sides of the electronic element 500.

[0050] As shown in Figures 5 to 9As shown, the guiding wall 34 is provided with a fixing groove 342 extending along the direction of the vertical limiting wall 31, and a buckling structure 3421 arranged in the fixing groove 342, the positioning foot 42 is provided with a buckling protrusion 421 buckling with the buckling structure 3421, and the fixing groove 342 penetrates the guiding structure 341, so that the positioning foot 42 can fix the cover body 4 and limit the electronic element 500 at the same time.

[0051] In the embodiment, the cover body 4 is provided with two groups of the positioning feet 42, one group of the positioning feet 42 is located at the rear side and cooperates with the fixing groove 342 on the guiding wall 34, and the other group of the positioning feet 42 is located at the front side, and the base 32 of the insulating seat 3 is provided with a fixing hole 322 penetrating up and down and cooperating with the other group of the positioning feet 42.

[0052] As shown, Figures 1 to 4 The cover body 4 is also provided with a shielding part 43 extending from the position adjacent to the second opening 36 of the cover plate part 41 to the direction of the limiting wall 31. The extension length of the shielding part 43 is less than the length of the positioning foot 42, but extends close to the electronic element 500 to sufficiently shield the connection position of the conductive element 2 and the electronic element 500.

[0053] As can be seen, the present application not only relates to the temperature sensing assembly 100, but also relates to an electronic device comprising the temperature sensing assembly 100 and the electronic element 500 electrically connected with the temperature sensing assembly 100, and the temperature sensing assembly 100 is arranged to electrically connect the temperature sensing element 3 with the electronic element 500 through the conductive element 2, and when the temperature sensing element 3 fails, the temperature sensing element 3 can be easily disassembled and replaced.
