[0054] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary.

[0055] Next, refer toFigures 1 - 12 Describe the base 100 of the temperature measuring element according to an embodiment of the present utility model.

[0056] As Figure 1 and Figure 3 As shown, the base 100 of the temperature measuring element according to the first aspect embodiment of the present utility model includes: a base body 10 and a conductive sheet 20. The base body 10 includes a base plate 101 and a boss 13. The boss 13 is provided on the base plate 101, and the boss 13 protrudes from the base plate 101 along a first direction. The base body 10 is provided with a through hole 131 that penetrates at least the base plate 101 along the first direction. The conductive sheet 20 has a conductive end 21. The conductive sheet 20 is adapted to pass through the through hole 131, and the boss 13 is used to support the conductive end 21.

[0057] Specifically, in a traditional base of a temperature measuring element, the conductive sheet is connected to the base body. For example, two conductive sheets are connected to the base body, and there is a problem of inaccurate positioning of the positions of the two conductive sheets on the base body. The temperature measuring element is connected to the conductive sheet. Since the position of the conductive sheet is inaccurate, it will affect the position of the temperature measuring element. In this way, the temperature measuring element cannot quickly contact the medium due to inaccurate setting position, which affects the measurement accuracy. Moreover, the inaccurate position of the conductive sheet will also affect the electrical connection between the conductive sheet and the circuit board.

[0058] Therefore, the base 100 of the temperature measuring element is provided with a boss 13. Since the base 100 of the temperature measuring element is formed by overmolding, during the demolding process, the conductive sheet 20 is arranged corresponding to the boss 13, which can make the position of the conductive sheet 20 set more accurately. Since the temperature measuring element 61 is connected to the conductive sheet 20, it can ensure that the temperature measuring element 61 quickly contacts the medium, thereby ensuring the accuracy of the temperature measuring element 61. The boss 13 can make the conductive sheet 20 in a centered position, thereby preventing the conductive sheet 20 from interfering with other parts of the temperature measuring element 61.

[0059] Wherein, the base body 10 has a first side 11 and a second side 12 opposite to each other along its axial direction. The first direction is the direction from the first side 11 to the second side 12. The base body 10 is provided with a boss 13 protruding along the first direction. The base body 10 is provided with a through hole 131 that penetrates at least the base plate 101 along the first direction. The conductive sheet 20 passes through the through hole 131 and is supported on the boss 13 through the conductive end 21. An elastic conductive member 80 can be provided between the conductive sheet 20 and the circuit board 30. The conductive end 21 of the conductive sheet 20 can be electrically connected to the circuit board 30 through the elastic conductive member 80, or the conductive end 21 on the conductive sheet 20 can be directly electrically connected to the circuit board 30. By supporting the conductive end 21 with the boss 13, the position of the conductive end 21 is more accurate, and thus the electrical connection between the conductive sheet 20 and the circuit board 30 is more stable and reliable.

[0060] Thus, the base 100 of the temperature measuring element can accurately position the conductive sheet 20, thereby ensuring the accuracy of the position of the temperature measuring element 61 and the reliability of the electrical connection between the conductive sheet 20 and the circuit board 30, and also preventing interference between the conductive sheet 20 and other parts of the temperature measuring element 61.

[0061] According to some embodiments of the present invention, the through hole 131 penetrates the seat plate 101 and the boss 13 along the first direction.

[0062] Wherein, the conductive sheet 20 can pass through the through hole 131 and sequentially pass through the seat plate 101 and the boss 13, so that the conductive end 21 of the conductive sheet 20 can be supported on the boss 13.

[0063] According to some embodiments of the present invention, as Figure 6 shown, the boss 13 is provided with a supporting plane 14, the conductive sheet 20 passes through the through hole 131, and the conductive end 21 covers the supporting plane 14.

[0064] Wherein, a supporting plane 14 is formed at the upper end of the boss 13, and the conductive end 21 of the conductive sheet 20 is in contact and cooperation with the supporting plane 14, which can increase the contact area between the conductive end 21 of the conductive sheet 20 and the supporting surface, so that the electrical connection between the conductive end 21 of the conductive sheet 20 and the circuit board 30 is more stable.

[0065] According to some embodiments of the present invention, the part of the through hole 131 located on the supporting plane 14 is arranged adjacent to the edge of the supporting plane 14.

[0066] Wherein, a through hole 131 is formed in the boss 13 to facilitate the threading of the conductive sheet 20. The part of the through hole 131 located on the supporting plane 14 is arranged adjacent to the edge of the supporting plane 14, and the shape of the through hole 131 corresponds to that of the conductive sheet 20. Since the conductive sheet 20 is in the shape of a strip, the through hole 131 is set as a strip hole. The strip hole can play a guiding role for the threading of the conductive sheet 20 and can also position the position of the conductive sheet 20, thereby preventing the conductive sheet 20 from being misaligned in the seat body 10 and affecting the measurement accuracy. By arranging the part of the through hole 131 located on the supporting plane 14 adjacent to the edge of the supporting plane 14, the contact area between the conductive end 21 and the supporting plane 14 can be further increased, thereby further making the electrical connection between the conductive end 21 and the circuit board 30 more stable.

[0067] According to some embodiments of the present invention, as Figure 6 shown, the outer contour of the cross-section of the boss 13 is configured as a rectangle, and the part of the through hole 131 on the supporting plane 14 is parallel and adjacent to one side of the rectangle.

[0068] Among them, the rectangular conductive boss can facilitate the positioning of the conductive sheet 20. The through hole 131 is arranged parallel to and adjacent to one side of the rectangle, which can ensure the perpendicularity of the conductive sheet 20 relative to the base body 10, thereby ensuring the accuracy of measurement.

[0069] According to some embodiments of the present invention, as Figure 6 shown, a receiving groove 132 is formed on the surface of the boss 13 away from the base plate 101, and the bottom surface of the receiving groove 132 forms a supporting plane 14.

[0070] Among them, the conductive end 21 can be placed in the receiving groove 132, and the receiving groove 132 wraps the conductive end 21, which can not only limit the position of the conductive end 21 in the horizontal direction to ensure the accuracy of measurement, but also play a role in protecting the conductive end 21.

[0071] According to specific embodiments of the present invention, as Figure 6 shown, the base body 10 further includes: an outer ring plate 102, the outer ring plate 102 is arranged around the base plate 101 and extends along the first direction, and the outer ring plate 102 and the base plate 101 jointly enclose an open cavity, wherein the boss 13 is arranged in the cavity.

[0072] Specifically, the base body 10 is mainly composed of the base plate 101 and the outer ring plate 102. The outer ring plate 102 is annularly arranged around the base plate 101 to form an open cavity, and the cavity can accommodate the boss 13. The conductive sheet 20 is arranged corresponding to the boss 13, so as to position the setting position of the conductive sheet 20.

[0073] According to specific embodiments of the present invention, as Figure 6 shown, along the first direction, the end of the boss 13 away from the base plate 101 does not exceed the end of the outer ring plate 102 away from the base plate 101.

[0074] Specifically, the end of the boss 13 away from the base plate 101 can be lower than the end of the outer ring plate 102 away from the base plate 101. In this way, the outer ring plate 102 can abut against the circuit board 30, and the conductive end 21 of the conductive sheet 20 can be conveniently electrically connected to the circuit board 30 through the elastic conductive member 80, and it is also convenient for the elastic conductive member 80 to be accommodated in the cavity. Thus, the outer ring plate 102 plays a role in protecting the elastic conductive member 80, and by reasonably using the space, the structure can be made more compact.

[0075] According to some embodiments of the present invention, as Figure 6 shown, a plurality of anti-collision protrusions 104 are arranged at intervals at the end of the outer ring plate 102 away from the base plate 101.

[0076] Among them, the anti-collision protrusions 104 on the outer ring plate 102 can eliminate the gap between the outer ring plate 102 and the circuit board 30 during the assembly process, prevent the outer ring plate 102 from colliding with the circuit board 30, and thus improve safety.

[0077] In addition, the circuit board 30 is arranged in the installation groove formed by the support frame 92, which can avoid damage to the circuit board 30 and play a role in protecting the circuit board 30. The inner wall of the installation groove of the circuit board 30 is provided with a circuit board fixing part 923, and the circuit board 30 is connected to the circuit board fixing part 923. Moreover, the placement surface of the circuit board 30 is designed with a grounding port, which can also ensure the accuracy of the installation direction of the circuit board 30. Among them, the connector 90 and the support frame 92 are snap-fitted to form a detection component 94, which can ensure the effective connection between the connector 90 and the circuit board 30 and ensure the normal communication function. Moreover, the circuit board 30 is a ceramic circuit board 30, and the ceramic circuit board 30 has a greater hardness than the flexible circuit board 30, which can avoid damage during the press-fitting process.

[0078] Furthermore, the support frame 92 is provided with a first support frame positioning part 921, and the connector 90 is provided with a connector positioning part 901. The first support frame positioning part 921 and the connector positioning part 901 are one of a positioning protrusion and a positioning hole. For example, when the first support frame positioning part 921 is a positioning hole, correspondingly, the connector positioning part 901 is a positioning protrusion. The positioning cooperation between the first support frame positioning part 921 and the connector positioning part 901 can enable the support frame 92 and the connector 90 to perform accurate and rapid positioning cooperation, thereby avoiding damage to the support frame 92 and the connector 90 during the installation process.

[0079] In addition, the connector 90, the circuit board 30 and the support frame 92 form a detection component 94. When the detection component 94 is connected and cooperated with the housing 91, among them, the support frame 92 is provided with a second support frame positioning part 922, and the housing 91 is provided with a housing 91 positioning part 103. The second support frame positioning part 922 and the housing 91 positioning part 103 are one of a positioning protrusion and a positioning hole. For example, when the second support frame positioning part 922 is a positioning protrusion, correspondingly, the housing 91 positioning part 103 is a positioning protrusion. The positioning cooperation between the second support frame positioning part 922 and the housing 91 positioning part 103 can realize the positioning installation of the support frame 92 and the housing 91.

[0080] Furthermore, a sealing ring 93 is arranged between the circuit board 30 and the housing 91. The sealing ring 93 is placed on the housing 91, and a support platform is formed at the housing 91. The annular support platform on the housing 91 can provide an installation position for the placement of the sealing ring 93, which can increase the contact area between the sealing ring 93 and the annular support platform, thereby preventing the sealing ring 93 from being damaged due to overpressure and causing the sealing effect of the sealing ring 93 to fail.

[0081] Furthermore, after the detection component 94 is properly installed in the housing 91, the upper edge of the housing 91 will be riveted, which can fix the installation position of the detection component 94, ensure effective sealing, and at the same time, vulcanized silicone rubber (RTV glue) is applied around the riveting circumference, so as to prevent external water vapor from entering the cavity circuit board 30 and damaging the circuit board 30.

[0082] According to some embodiments of the present invention, as Figure 6 and Figure 7 shown, there are multiple conductive sheets 20 and multiple bosses 13. The multiple bosses 13 are arranged at intervals, and the multiple bosses 13 respectively support the conductive ends 21 of the multiple conductive sheets 20 one by one, or there are multiple conductive sheets 20 and one boss 13, and the boss 13 is provided with multiple through holes 131. The multiple conductive sheets 20 are arranged at intervals and respectively cooperate with the multiple through holes 131 of the boss 13 one by one.

[0083] Among them, the corresponding setting of the conductive sheet 20 and the boss 13 can facilitate the positioning of the conductive sheet 20, so that the conductive sheet 20 can be in the centered position. For example, two conductive sheets 20 can be provided, and correspondingly, two bosses 13 are also correspondingly provided. Each conductive sheet 20 is positioned corresponding to each boss 13, which can prevent the misinstallation of the temperature measuring element 61. The two bosses 13 are arranged at intervals, so as to avoid interference between the two conductive sheets 20.

[0084] Furthermore, the boss 13 is provided with through holes 131, and the conductive sheet 20 is inserted into the through holes 131. Among them, the two conductive sheets 20 are respectively inserted into the two through holes 131. In this way, the positioning of the conductive sheet 20 can be further carried out, so as to ensure the accuracy of the position of the conductive sheet 20.

[0085] Also, when two conductive sheets 20 are provided, one boss 13 can be provided. One boss 13 can ensure that the two conductive sheets 20 are in the centered position. Two through holes 131 can be opened in one boss 13. In this way, the two conductive sheets 20 can be respectively inserted into the two through holes 131, so as to further ensure the accuracy of the positions of the two conductive sheets 20.

[0086] According to the specific embodiments of the present invention, as Figure 3 and Figure 6 shown, the conductive sheet 20 is provided with at least one welding position 40, so as to be used for welding connection with the temperature measuring element 61.

[0087] Specifically, two spaced welding positions 40 can be provided on each conductive sheet 20. Since the temperature measuring element 61 is welded to the two conductive sheets 20, accordingly, the temperature measuring element 61 has two welding ends, and each welding end is welded to the two spaced welding positions 40 of each conductive sheet 20. When the conductive sheet 20 is in the centered position of the seat body 10, the welding ends of the temperature measuring element 61 are between the two welding positions 40, which can further ensure that the temperature measuring element 61 is in the centered position, and can also enable the temperature measuring element 61 to be welded in the appropriate position, avoiding the situation that the temperature measuring element 61 cannot quickly contact the medium due to too low or too high welding, which affects the test performance. Therefore, by designing the welding positions 40 on the two conductive sheets 20, the welding position of the temperature measuring element 61 can be ensured, and the temperature measuring element 61 can be welded at an appropriate height, thereby improving the measurement speed and ensuring the measurement accuracy.

[0088] According to some embodiments of the present invention, as Figure 3 shown, the first direction is perpendicular to the seat plate 101.

[0089] Wherein, the first direction is the direction from bottom to top, and the first direction is perpendicular to the seat plate 101, which can ensure the perpendicularity of the conductive sheet 20 mounted on the boss 13 of the seat plate 101, thereby ensuring the measurement accuracy.

[0090] According to some embodiments of the present invention, as Figure 5 shown, a positioning portion 103 is provided on the outer peripheral wall of the seat body 10, and the positioning portion 103 is used to fix the relative position of the seat body 10 and the housing 91 in the circumferential direction of the housing 91.

[0091] Wherein, a positioning portion 103 is provided on the outer peripheral wall of the seat body 10, and the positioning portion 103 cooperates with the housing 91, thereby preventing the seat body 10 from rotating circumferentially relative to the housing 91 and ensuring the stability of the cooperation between the seat body 10 and the housing 91.

[0092] According to specific embodiments of the present invention, as Figure 5 shown, the positioning portion 103 is configured as one of a positioning groove and a positioning protrusion.

[0093] Specifically, the positioning portion 103 of the seat body 10 can be set as a positioning groove. Correspondingly, the housing 91 is provided with a positioning protrusion, and the positioning protrusion extends into the positioning groove, which can position the installation positions of the seat body 10 and the housing 91, thereby preventing the seat body 10 from rotating circumferentially relative to the housing 91.

[0094] Further, when the positioning portion 103 of the seat body 10 is provided as a positioning protrusion, correspondingly, the housing 91 is provided with a positioning groove. The positioning protrusion extends into the positioning groove, which can position the installation positions of the seat body 10 and the housing 91, and thus can also prevent the seat body 10 from rotating circumferentially relative to the housing 91.

[0095] According to a second aspect embodiment of the present utility model, the temperature measuring assembly 60 includes: a temperature measuring element 61, the temperature measuring element base 100 of the above embodiment, and a protective sleeve 70. The temperature measuring element 61 is connected to the conductive sheet 20, the protective sleeve 70 covers the temperature measuring element 61, and the protective sleeve 70 is provided with a temperature measuring hole for the medium to contact the temperature measuring element 61.

[0096] Among them, the temperature measuring element 61 is welded to the conductive sheet 20. If the temperature measuring element 61 is welded too low, it will exceed the protective sleeve 70, or if it is welded too high, it cannot quickly contact the medium, thus affecting the accuracy of temperature measurement. At the same time, the welding position 40 also plays a role in centering the temperature measuring element 61, so as to ensure that the temperature measuring element 61 does not contact the wall surface of the protective sleeve 70.

[0097] Further, there is a clearance fit between the temperature measuring element 61 and the protective sleeve 70. The protective sleeve 70 is provided with a temperature measuring hole for the medium to contact the temperature measuring element 61. The setting of the temperature measuring hole can ensure that the medium contacts the temperature measuring element 61 in time, so that the temperature measuring element 61 can accurately obtain the temperature of the medium. The temperature measuring element 61 can be an NTC thermistor.

[0098] Furthermore, the protective sleeve limiting portion 73 on the protective sleeve 70 is provided as a groove, which can cooperate with the protrusion provided on the inner wall of the housing 91. It can not only play a positioning role, but also prevent circumferential rotation between the protective sleeve 70 and the housing 91, so as to ensure the correct installation of the protective sleeve 70 and the housing 91.

[0099] According to some embodiments of the present utility model, as Figure 5 shown, the temperature measuring hole includes a first temperature measuring hole 71 and a second temperature measuring hole 72. The first temperature measuring hole 71 is provided on the end face of the end of the protective sleeve 70 away from the seat body 10, and the second temperature measuring hole 72 is provided on the circumferential wall of the end of the protective sleeve 70 away from the seat body 10.

[0100] Among them, the first temperature measuring hole 71 is provided on the end face of the end of the protective sleeve 70 away from the seat body 10, which can facilitate the medium to enter from the first temperature measuring hole 71 and can also quickly contact the medium for temperature measurement.

[0101] Further, the setting of the second temperature measuring hole 72 on the circumferential wall of the protective sleeve 70 can further increase the contact area between the medium and the circumferential direction of the protective sleeve 70 and the temperature measuring element 61, so as to ensure the accuracy of temperature measurement and can also accelerate the contact rate between the medium and the temperature measuring element 61.
