[0045] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0046] Reference below Figure 1-Figure 10 The protective cover 20 for the sensor 1 according to the embodiment of the present invention is described.

[0047] like Figure 1 and Figure 3 As shown, the sensor 1 includes: a temperature sensing element 10. The temperature sensing element 10 mainly senses and measures the temperature of the corresponding medium. The temperature sensing element 10 can be an NTC thermistor.

[0048] like Figure 2 and Figure 6 As shown, the protective sleeve 20 is provided with a matching hole 21 penetrating along the axial direction thereof, for matching with the temperature sensing element 10. The protective sleeve 20 has an axial direction, a first direction, and a second direction, and the axial direction, the first direction, and the second direction are arranged perpendicularly in pairs, and the matching hole 21 is at least partially in a cross section perpendicular to the axial direction, and the size of the matching hole 21 in the first direction is greater than the size of the matching hole 21 in the second direction.

[0049] Among them, the matching hole 21 mainly serves to install the temperature sensing component 10, and the temperature sensing component 10 cooperates with the matching hole 21 along the axial direction, so that the temperature sensing component 10 can be installed inside the protective sleeve 20, so that the protective sleeve 20 can be used to protect the temperature sensing component 10, and the temperature sensing component 10 can work better.

[0050] Specifically, the axial direction is the axial extension direction of the protective sleeve 20, and the size of the matching hole 21 in the first direction is larger than the size of the matching hole 21 in the second direction. It can be understood that the temperature sensing component 10 has the largest size in a certain direction. In this way, when the temperature sensing component 10 is installed, the direction in which it has the largest size is consistent with the first direction. At this time, it can effectively ensure that there is enough space between the temperature sensing component 10 and the inner wall of the protective sleeve 20, thereby avoiding contact between the temperature sensing component 10 and the protective sleeve 20, thereby protecting the temperature sensing component 10 and enabling the temperature sensing component to work better.

[0051] In some embodiments of the present invention, Figure 6 As shown, the matching hole 21 is an elliptical hole, and the first direction is the long axis direction of the elliptical hole. In other words, the matching hole 21 can be in the shape of an elliptical hole, the first direction is the long axis direction of the elliptical hole, and the second direction is the short axis direction of the elliptical hole. The length of the elliptical hole in the first direction is greater than the length of the elliptical hole in the second direction. At this time, the direction in which the temperature sensing component 10 has the largest size is consistent with the long axis direction of the elliptical hole, so that the temperature sensing component 10 can be prevented from contacting with the protective cover 20, thereby protecting the temperature sensing component 10.

[0052] In addition, if Figure 6 As shown, the protective sleeve 20 includes an axial limiting portion 26, which is used to cooperate with the housing 40 of the sensor 1 to limit the relative position of the protective sleeve 20 and the housing 40 in the axial direction. The axial limiting portion 26 mainly plays a limiting role. The axial limiting portion 26 is limited and matched with the housing 40, so that after the protective sleeve 20 and the housing 40 are installed and matched, the axial position of the protective sleeve 20 and the housing 40 can be ensured to remain stable, so that the protective sleeve 20 can better protect the temperature sensing component 10, and the sensor 1 can work better.

[0053] Furthermore, if Figure 5 and Figure 6As shown, the protective sleeve 20 includes a first part 27 and a second part 28 that are fixedly connected. The outer diameter of the first part 27 is smaller than the outer diameter of the second part 28 to form a step surface, and the step surface is the axial limit portion 26. In other words, the cross-sectional shape of the protective sleeve 20 is a T-shaped structure, which can better adapt to the shell 40 and the temperature sensor 10. Moreover, the T-shaped structural design of the protective sleeve 20 can form a step surface, and the setting of the step surface can play a limiting role. After the protective sleeve 20 and the shell 40 are installed and matched, it can ensure that the axial position of the protective sleeve 20 and the shell 40 remains stable.

[0054] In addition, if Figure 5 and Figure 6 As shown, the protective sleeve 20 is provided with a circumferential limit portion 24, which is used to cooperate with the housing 40 of the sensor 1 to limit the relative position of the protective sleeve 20 and the housing 40 in the circumferential direction. Among them, the circumferential limit portion 24 mainly plays a limiting role. The circumferential limit portion 24 is provided on the protective sleeve 20, and the circumferential limit portion 24 is used to cooperate with the housing 40, so that after the protective sleeve 20 and the housing 40 are installed and matched, the position of the protective sleeve 20 and the housing 40 in the circumferential direction can be ensured to remain stable, so that the protective sleeve 20 can better protect the temperature sensing component 10, and the sensor 1 can work better.

[0055] In addition, if Figure 5 and Figure 6 As shown, the circumferential limiting portion 24 is configured as a groove disposed on the outer wall of the protective sleeve 20. The structure of the groove is simple and convenient for processing and setting. The groove is disposed on the outer wall of the protective sleeve 20. Since the housing 40 is located outside the protective sleeve 20, such a configuration is more reasonable and facilitates the limiting cooperation between the groove and the housing 40.

[0056] Furthermore, if Figure 5 and Figure 6 As shown, in the second direction, the circumferential limiting portion 24 is at least located on one side of the matching hole 21. It can be understood that the matching hole 21 has two opposite sides in the second direction, and the circumferential limiting portion 24 can be set on any side of the matching hole 21 in the second direction, and can also be set on both opposite sides of the matching hole 21 in the second direction at the same time. In other words, the number of circumferential limiting portions 24 is at least one, which can increase the setting space of the groove, and the groove can be used to better guide the medium, which is convenient for the subsequent measurement of the pressure of the medium. In addition, the circumferential limiting between the protective sleeve 20 and the shell 40 can be ensured in this way. When the number of circumferential limiting portions 24 is two, the number of limiting points between the protective sleeve 20 and the shell 40 can be increased, so that the circumferential limiting between the protective sleeve 20 and the shell 40 can be made more reliable.

[0057] Specifically, Figure 5and Figure 6 As shown, the circumferential limiting portion 24 is constructed as a groove that penetrates the protective sleeve 20 along the axial direction of the protective sleeve 20. It should be noted that the design of the groove can also play a role in guiding the circulation of the medium. Therefore, the groove is penetrated through the protective sleeve 20 along the axial direction of the protective sleeve 20, so that the groove can be used to better guide the medium, which is convenient for subsequent measurement of the pressure of the medium. In addition, the length of the groove can be extended, thereby increasing the circumferential limiting area between the protective sleeve 20 and the housing 40, making the limiting effect more reliable.

[0058] In addition, if Figure 5 and Figure 6 As shown, there are multiple opening grooves 23, and the multiple opening grooves 23 are evenly arranged in the circumferential direction of the protective sleeve 20. The design of multiple opening grooves 23 can make the setting of the opening grooves 23 more comprehensive, so that the external medium can contact the temperature sensing element 10 more quickly, thereby improving the sensing performance of the sensor 1. Moreover, the multiple opening grooves 23 are evenly arranged in the circumferential direction of the protective sleeve 20, which can make the setting of the multiple opening grooves 23 more reasonable, avoid mutual interference between adjacent opening grooves 23, and facilitate processing.

[0059] As an optional embodiment, there are four opening slots 23, and the four opening slots 23 are evenly arranged in the circumferential direction of the protective sleeve 20. In other words, the number of the opening slots 23 can be four, so that the arrangement of the four opening slots 23 can be more even, which is convenient for the external medium to enter the interior of the protective sleeve 20 from different directions through the corresponding opening slots 23, and then contact the temperature sensing element 10.

[0060] The temperature sensing assembly according to the embodiment of the utility model comprises: a temperature sensing member 10 and the protective sleeve 20 described in the above embodiment, and the temperature sensing member 10 is suitable for being arranged in the matching hole 21. The temperature sensing member 10 is the main part of the temperature sensing assembly, and the temperature sensing assembly can use the temperature sensing member 10 to measure the pressure and temperature of the corresponding medium.

[0061] In addition, if Fig.10As shown, the temperature sensing element 10 includes a conductive sheet 11 and a temperature sensing element 12. There are two conductive sheets 11, and the two conductive sheets 11 are spaced apart in the first direction. Among them, the conductive sheet 11 mainly plays a conductive role. There are two conductive sheets 11. It should be noted that the two conductive sheets 11 can form a loop with the corresponding components, that is, one conductive sheet 11 is a signal output end, and the other conductive sheet 11 is a signal input end. The two conductive sheets 11 are spaced apart in the first direction. At this time, the temperature sensing element 10 has a maximum size in the first direction. Since the size of the matching hole 21 of the protective sleeve 20 in the first direction is larger than the size in the second direction, the spacing between the two conductive sheets 11 can be as large as possible. This arrangement can avoid the contact between the two conductive sheets 11 and the inner wall of the protective sleeve 20 on the one hand, and on the other hand, it can avoid interference between the two conductive sheets 11, resulting in faults such as short circuits, so that the temperature sensing element 10 can work better. The temperature sensing element 12 mainly plays a temperature sensing role and can sense the temperature of the medium.

[0062] Furthermore, if Fig.10 As shown, the conductive sheet 11 is constructed as a sheet-like structure with its length extending along the first direction. This can prevent the conductive sheet 11 from contacting the protective cover 20 during installation and operation, thereby protecting the conductive sheet 11. Moreover, constructing the conductive sheet 11 as a sheet-like structure can also save materials and reduce costs.

[0063] Specifically, Figure 3 As shown, the temperature sensing element 12 is provided with two pins, and the two pins are respectively welded to the two conductive sheets 11. The pins mainly play the role of transmitting signals. The two pins are respectively welded to the two conductive sheets 11, so that the connection between the corresponding pins and the conductive sheets 11 can be stabilized, so that after the temperature sensing element 12 senses the temperature information of the medium, the medium temperature signal can be better transmitted to the corresponding component through the corresponding pins and the conductive sheets 11 for analysis and processing. Specifically, the conductive sheets 11 on both sides can form an information transmission loop between the corresponding pins and the temperature sensing element 12, which is convenient for controlling the temperature sensing element 12 and collecting the signal on the temperature sensing element 12.

[0064] Furthermore, if Fig.10 As shown, in the width direction of the conductive sheet 11, the conductive sheet 11 and the inner wall of the matching hole 21 are spaced apart at both ends in the first direction. In this way, a gap is left between the conductive sheet 11 and the inner wall of the matching hole 21 in the first direction, thereby preventing the conductive sheet 11 from contacting the inner wall of the matching hole 21 in the first direction, thereby protecting the conductive sheet 11 and enabling the temperature sensing element 10 to work better.

[0065] In addition, if Figure 3As shown, the temperature sensing element 12 is spaced apart from the inner wall of the protective sleeve 20. This arrangement is more reasonable, and a gap can be left between the temperature sensing element 12 and the inner wall of the protective sleeve 20, so that the medium can enter and contact the temperature sensing element 12, thereby improving the reliability of the temperature sensing element 12.

[0066] In addition, if Figure 5 and Figure 6 As shown, the protective sleeve 20 is provided with an open groove 23, and the open groove 23 is used for the medium to contact the temperature sensing part 10. Among them, the open groove 23 mainly plays a role of communication. It should be noted that the open groove 23 is arranged at one end of the protective sleeve 20 away from the mounting base 30, so that the external medium can enter the protective sleeve 20 through the open groove 23 and contact the temperature sensing part 10, thereby reducing the impact of the external medium directly on the temperature sensing part 10, so that the temperature sensing part 10 can be protected.

[0067] In addition, if Figure 1-Figure 6 As shown, the temperature sensing assembly also includes a mounting base 30, and the temperature sensing component 10 is connected to a side of the mounting base 30 adjacent to the protective sleeve 20. A first mating surface 22 is provided at one end of the protective sleeve 20, and a mating hole 21 is provided on the first mating surface 22. The mounting base 30 mainly serves the function of installation. The temperature sensing component 10 is connected to a side of the mounting base 30 adjacent to the protective sleeve 20, so that the temperature sensing component 10 can be fixed, making the setting of the temperature sensing component 10 more secure and stable, so that the temperature sensing component 10 can work better. It is also convenient for the temperature sensing component 10 to be installed and matched with the protective sleeve 20, so that the protective sleeve 20 can protect the temperature sensing component 10.

[0068] The first mating surface 22 mainly plays the role of installation and matching. The mounting base 30 is matched on the first mating surface 22, which can provide a matching position for the matching of the protective cover 20 and the mounting base 30, thereby facilitating the matching between the mounting base 30 and the protective cover 20. The matching hole 21 is opened on the first mating surface 22, so that the setting of the matching hole 21 is more reasonable. During installation, the distance between the matching hole 21 and the mounting base 30 and the temperature sensing component 10 is closer, which facilitates the temperature sensing component 10 to pass through the matching hole 21 and enter the interior of the protective cover 20. In addition, the elliptical structure design of the matching hole 21 can also ensure that there will be no large relative movement between the mounting base 30 and the protective cover 20, thereby ensuring the stability of the electrical connection of the sensor 1.

[0069] In addition, if Figure 1-Figure 6As shown, the conductive sheet 11 is fixed to the mounting base 30, and the protective sleeve 20 and the mounting base 30 are suitable for abutting in the axial direction. The conductive sheet 11 is fixed to the mounting base 30, so that the conductive sheet 11 can be fixed, and the setting of the conductive sheet 11 is more reliable and stable, so that the conductive sheet 11 can work better. The protective sleeve 20 and the mounting base 30 are abutted in the axial direction, so that the connection between the protective sleeve 20 and the mounting base 30 can be tighter, so that the medium can be prevented from entering the inside of the protective sleeve 20 through the gap between the protective sleeve 20 and the mounting base 30, affecting the measurement of the temperature sensing element 10, and also avoiding damage to the temperature sensing element 10.

[0070] Furthermore, if Figure 5 As shown, the mounting base 30 is provided with a limiting portion 31 which is circumferentially limited with the housing 40 of the sensor 1. The limiting portion 31 mainly plays a limiting role. The limiting portion 31 is arranged on the mounting base 30, and the limiting portion 31 is limited with the housing 40, so that after the protective cover 20 and the housing 40 are installed, the protective cover 20 and the housing 40 can be kept relatively stable in the circumferential direction, so that the setting of the protective cover 20 can be more secure and stable, and the protective cover 20 can work better.

[0071] The sensor 1 according to the embodiment of the utility model includes the temperature sensing component described in the above embodiment, and the temperature sensing component is suitable for being arranged in the housing 40. The temperature sensing component is arranged in the housing 40, so that the housing 40 can be used to protect the temperature sensing component, so that the temperature sensing component can work better.

[0072] Furthermore, if Figure 1-Figure 3 As shown, the sensor 1 also includes a shell 40, the protective sleeve 20 is limited and matched with the shell 40, and the mounting base 30 is limited and matched with the shell 40. The shell 40 mainly plays the role of installation and matching. The protective sleeve 20 is limited and matched with the shell 40, so that after the protective sleeve 20 is installed inside the shell 40, the shell 40 can be used to limit the position of the protective sleeve 20, so that the setting of the protective sleeve 20 can be more stable, and the protective sleeve 20 can better play a protective role. Similarly, the mounting base 30 is limited and matched with the shell 40, so that after the mounting base 30 is installed inside the shell 40, the shell 40 can be used to limit the mounting base 30, so that the setting of the mounting base 30 can be more stable, and the mounting base 30 can work better. Moreover, the shell 40 can also play a protective role, and can protect the mounting base 30 and the protective sleeve 20 installed in the shell 40.

[0073] Specifically, Figure 5 and Figure 6As shown, a first limiting portion is provided on the shell 40, a circumferential limiting portion 24 is provided on the protective sleeve 20, and a limiting portion 31 is provided on the mounting base 30, and the circumferential limiting portion 24 and the limiting portion 31 are respectively matched with the first limiting portion. Among them, the first limiting portion, the circumferential limiting portion 24 and the limiting portion 31 can all play a limiting role. The first limiting portion is provided on the shell 40, and the circumferential limiting portion 24 is provided on the protective sleeve 20, so that the first limiting portion can cooperate with the circumferential limiting portion 24, so that the shell 40 can be used to limit the protective sleeve 20, avoiding a large deflection of the protective sleeve 20 relative to the shell 40, making the setting of the protective sleeve 20 more stable, so that the sensor 1 can work more stably, and it is also convenient to install the protective sleeve 20. Similarly, the limiting portion 31 is set on the mounting base 30, so that the limiting portion 31 can also cooperate with the first limiting portion, so that the mounting base 30 can be limited by the shell 40 to avoid a large deflection of the mounting base 30 relative to the shell 40, so that the setting of the mounting base 30 is more stable, so that the sensor 1 can work more stably and it is also convenient to install the mounting base 30.

[0074] In addition, if Figure 5 As shown, in the axial direction, the circumferential limit portion 24 is aligned with the limit portion 31. As can be seen from the above, the circumferential limit portion 24 and the limit portion 31 are both matched with the first limit portion. Therefore, the circumferential limit portion 24 is aligned with the limit portion 31, which can facilitate the circumferential limit portion 24 and the limit portion 31 to cooperate with the first limit portion at the same time, and after the circumferential limit portion 24 and the limit portion 31 cooperate with the first limit portion at the same time, the position between the protective sleeve 20 and the mounting base 30 can also be kept relatively stable. It should be noted that the cooperation between the circumferential limit portion 24 and the limit portion 31 and the first limit portion is mainly to limit the circumferential rotation of the protective sleeve 20 and the mounting base 30. The circumferential limit portion 24 and the limit portion 31 can be a limit groove, and the first limit portion can be a limit block.

[0075] In addition, if Figure 3 As shown, a step portion 41 is provided in the housing 40, and the protective sleeve 20 is also provided with a second mating surface 25. In the first axial direction, the second mating surface 25 is limitedly matched with the surface of the step portion 41. Among them, the step portion 41 and the second mating surface 25 can both play a role of limiting. The step portion 41 is provided in the housing 40, and the second mating surface 25 is provided on the protective sleeve 20. In this way, when the protective sleeve 20 is installed on the housing 40, the protective sleeve 20 can be limited in the axial direction by the cooperation between the step portion 41 and the second mating surface 25, so that the installation of the protective sleeve 20 can be more accurate, the assembly efficiency is improved, and the setting of the protective sleeve 20 can also be made more stable.

[0076] Furthermore, if Figure 2 and Figure 3 As shown, the sensor 1 also includes a pressure sensing component 50, which is arranged in the housing 40. A protective component 32 is arranged at one end of the mounting base 30 away from the protective sleeve 20. In the second axial direction, the protective component 32 abuts against the pressure sensing component 50, and the second axial direction is opposite to the first axial direction. The pressure sensing component 50 mainly senses and measures pressure. The pressure sensing component 50 is arranged in the housing 40, so that the housing 40 can be used to protect the pressure sensing component 50, so that the pressure sensing component 50 can work better.

[0077] The protective member 32 mainly plays a protective role. The protective member 32 is set at one end of the mounting base 30 away from the protective sleeve 20, so that in the second axial direction, the protective member 32 can abut against the pressure sensing member 50, so that the protective member 32 can be used to eliminate the gap between the pressure sensing member 50 and the mounting base 30, thereby avoiding the collision between the pressure sensing member 50 and the mounting base 30, thereby affecting the normal use of the sensor 1. It should be noted that the second axial direction is opposite to the first axial direction. Specifically, the first axial direction is the direction of the pressure sensing member 50 toward the protective sleeve 20, and the second axial direction is the direction of the protective sleeve 20 toward the pressure sensing member 50.

[0078] It should be noted that when the pressure sensing component 50 is press-fitted, the protective component 32 will be partially damaged, which can ensure zero contact between the pressure sensing component 50 and the mounting base 30, thereby eliminating the gap between the pressure sensing component 50 and the mounting base 30, thereby avoiding collision between the pressure sensing component 50 and the mounting base 30.

[0079] In addition, if Figure 2 and Figure 3 As shown, the sensor 1 also includes a sealing member 60, which is spaced apart from the mounting base 30, and the sealing member 60 is sealingly disposed between the pressure sensing member 50 and the housing 40. The sealing member 60 mainly plays a sealing role. It should be noted that the sealing member 60 is sleeved on the mounting base 30, so the sealing member 60 is spaced apart from the mounting base 30, that is, there is a gap between the sealing member 60 and the mounting base 30, which facilitates the installation of the sealing member 60. Moreover, the sealing member 60 is sealingly disposed between the pressure sensing member 50 and the housing 40, so that the sealing member 60 can seal the gap between the pressure sensing member 50 and the housing 40.

[0080] As an optional embodiment, it should be noted that, since the pressure sensing component 50 squeezes the sealing component 60, the sealing component 60 is deformed, so that the sealing component 60 can better play a sealing role. However, in order to protect the sealing component 60 and prevent the sealing component 60 from being damaged, a pressure stop surface can be provided inside the housing 40, and the pressure stop surface is mainly used to limit the movement of the support component, thereby limiting the degree of squeezing of the sealing component 60 by the pressure sensing component 50.

[0081] In addition, the sensor 1 also includes a support member 70, which is provided with a first positioning portion 71 and an abutment portion 72. A second positioning portion is provided on the shell 40, the first positioning portion 71 is positioned and matched with the second positioning portion, and the abutment portion 72 abuts and matches with the outer wall surface of the pressure sensing component 50.

[0082] Among them, the support member 70 mainly plays the role of support and installation. The first positioning portion 71 and the second positioning portion can both play the role of positioning. The first positioning portion 71 is set on the support member 70, and the second positioning portion is set on the shell 40. In this way, when the support member 70 is matched with the shell 40, the first positioning portion 71 and the second positioning portion can be used to calibrate the position between the support member 70 and the shell 40, so that the installation between the support member 70 and the shell 40 can be more accurate and fast, thereby improving the assembly efficiency. The abutment portion 72 can play the role of abutment. The abutment portion 72 is set on the support member 70. In this way, when the pressure sensing member 50 is connected to the support member 70, the abutment portion 72 can abut the outer wall surface of the pressure sensing member 50, so that the connection between the pressure sensing member 50 and the support member 70 can be more reliable and stable, and the pressure sensing member 50 can work better.

[0083] Furthermore, if Figure 1-Figure 3 As shown, the sensor 1 further includes a connecting member 80, which abuts against the side of the pressure sensing member 50 away from the mounting base 30. The connecting member 80 mainly serves the function of connecting and installing. The connecting member 80 abuts against the side of the pressure sensing member 50 away from the mounting base 30, that is, the connecting member 80 and the supporting member 70 are respectively located on both sides of the pressure sensing member 50. The connecting member 80 abuts against the side of the pressure sensing member 50 away from the mounting base 30, which can further improve the stability of the pressure sensing member 50.

[0084] It should be noted that the seal 60 can separate the gap between the pressure sensing component 50 and the housing 40 into two areas, that is, the inside of the seal 60 is the medium contact area, and the outside of the seal 60 is the medium isolation area, and the limit portion 31 is also a pressure inlet while limiting, and the medium can enter the medium contact area from the limit portion 31, and then can perform contact sensing with the pressure sensing component 50. Specifically, when the sensor 1 measures the pressure of the medium, the medium can successively enter the medium contact area along the circumferential limit portion 24 and the limit portion 31 to perform contact sensing with the pressure sensing component 50, and the pressure sensing component 50 will transmit the corresponding signal to the connector 80 after sensing, and then output the signal to the outside of the sensor 1.

[0085] Similarly, when the sensor 1 measures the temperature of the medium, the medium can enter the protective cover 20 through the slot 23 and contact the temperature sensing element 10. The temperature sensing element 10 transmits the sensed medium temperature signal to the pressure sensing element 50 through the mounting base 30. The pressure sensing element 50 is provided with an electrical connection hole. The medium temperature signal can be transmitted to the connector 80 along the bottom of the pressure sensing element 50 and the electrical connection hole in turn, and then the signal is output to the outside of the sensor 1. The electrical connection hole is located in the medium isolation area, which can prevent the medium from leaking through the electrical connection hole and causing damage to the internal components of the sensor 1.

[0086] Specifically, Figure 2 and Figure 7 As shown, the connector 80 is provided with a third positioning portion 81 and a first plug-in portion 82, and the support member 70 is also provided with a fourth positioning portion 74 and a second plug-in portion 73. The third positioning portion 81 is positioned and matched with the fourth positioning portion 74, and the first plug-in portion 82 is plug-matched with the second plug-in portion 73. Among them, the third positioning portion 81 and the fourth positioning portion 74 can both play a positioning role. The third positioning portion 81 is arranged on the connector 80, and the fourth positioning portion 74 is arranged on the support member 70. In this way, when the connector 80 is installed and matched with the support member 70, the third positioning portion 81 and the fourth positioning portion 74 can be used to calibrate the position between the connector 80 and the support member 70, so that the installation between the connector 80 and the support member 70 can be more accurate and fast, thereby improving the assembly efficiency.

[0087] Both the first plug-in portion 82 and the second plug-in portion 73 can play a plug-in role. The first plug-in portion 82 is arranged on the connector 80, and the second plug-in portion 73 is arranged on the support member 70. In this way, when the connector 80 and the support member 70 are installed and matched, the first plug-in portion 82 can be plugged and matched with the second plug-in portion 73, so that the connection between the connector 80 and the support member 70 can be more stable. It should be noted that after the connector 80 and the support member 70 are installed, they can wrap the pressure sensing member 50 located in the middle to a certain extent, so as to avoid contact between the pressure sensing member 50 and the housing 40, thereby avoiding damage to the pressure sensing member 50 during the press-fitting process, and ensuring the effective connection between the connector 80 and the pressure sensing member 50.

[0088] As an optional embodiment, the pressure sensing element 50 is a ceramic element. That is, the circuit board in the pressure sensing element 50 can be a ceramic circuit board, which can better prevent the sensor 1 from being damaged during installation compared to a flexible circuit board. Moreover, when the pressure sensing element 50 presses the sealing element 60, the ceramic material can better press the sealing element 60, thereby ensuring the sealing of the sensor 1.

[0089] As an optional embodiment, the housing 40 and the connector 80 may be fixed by riveting, which can ensure the sealing of the seal 60. At the same time, RTV glue may be applied around the riveting position to prevent external water vapor from entering the sensor 1 and damaging the pressure sensing element 50.

[0090] It should be noted that the connector 80, the pressure sensing component 50 and the support component 70 can form a detection unit, which can protect the pressure sensing component 50, prevent the pressure sensing component 50 from colliding with the housing 40, and effectively ensure the connection between the pressure sensing component 50 and the connector 80 to ensure that their communication function is normal. The temperature sensing component 10, the protective cover 20, and the mounting base 30 can form a temperature sensing unit. The temperature sensing unit and the detection unit are sequentially placed inside the housing 40, which can reduce the installation steps of the process and improve production efficiency.
