DETAILED DESCRIPTION
[0041] 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.
[0042] Reference below Figure 1-Figure 10 The sensor 1 according to the embodiment of the utility model is described. The sensor 1 in the present application can be a temperature and pressure sensor 1, which can measure the pressure and temperature of the corresponding medium.
[0043] like Figure 2 and Figure 3 As shown, the sensor 1 according to the embodiment of the utility model comprises: a housing 10, a pressure sensing component 20 and a connector 30. The housing 10 mainly plays the role of installation and matching. The pressure sensing component 20 is mainly used to sense the pressure information of the medium. The connector 30 mainly plays the role of connection and installation.
[0044] like Fig. 9 As shown, the housing 10 is provided with a first positioning portion 13. The first positioning portion 13 mainly plays a positioning role. When the housing 10 is installed and matched with corresponding components, the first positioning portion 13 can improve the installation accuracy.
[0045] like Figure 2 and Figure 3 As shown, the pressure sensing component 20 includes a support member 21, and the support member 21 is arranged on the shell 10. The support member 21 is provided with a second positioning portion 211. Among them, the support member 21 mainly plays the role of support and installation. The support member 21 can install and support the corresponding components on the pressure sensing component 22, so that the pressure sensing component 20 can work better. The support member 21 is arranged on the shell 10, so that the connection between the support member 21 and the shell 10 can be more stable, so that the support member 21 can perform the supporting work more stably. The second positioning portion 211 also mainly plays the role of positioning. The second positioning portion 211 is arranged on the support member 21, so that when the support member 21 cooperates with the corresponding components, the second positioning portion 211 can improve the installation accuracy.
[0046] like Figure 2 and Figure 8As shown, the connector 30 is provided with a third positioning portion 31, and the third positioning portion 31 is positioned and matched with the first positioning portion 13, and the third positioning portion 31 is positioned and matched with the second positioning portion 211. Among them, the third positioning portion 31 also mainly plays a positioning role. The third positioning portion 31 is arranged on the connector 30, so that when the connector 30 is matched with the corresponding component, the installation accuracy can be improved by the third positioning portion 31. Specifically, the third positioning portion 31 is positioned and matched with the first positioning portion 13, and the third positioning portion 31 is positioned and matched with the second positioning portion 211. In other words, the third positioning portion 31 can be matched with the first positioning portion 13 and the second positioning portion 211 at the same time, that is, when the connector 30 is installed, the third positioning portion 31 can be used to cooperate with the first positioning portion 13 and the second positioning portion 211 to position with the support member 21 and the housing 10, so that the connection between the connector 30 and the support member 21 and the housing 10 can be more accurate and stable.
[0047] Therefore, by providing a third positioning portion 31 on the connecting member 30, and the third positioning portion 31 simultaneously cooperating with the second positioning portion 211 on the supporting member 21 and the first positioning portion 13 on the shell 10, the snap fit between the connecting member 30 and the supporting member 21 and the shell 10 can be improved, making the connection between the connecting member 30 and the supporting member 21 and the shell 10 more accurate and stable, thereby improving the assembly accuracy of the sensor 1 and simplifying the assembly steps.
[0048] In addition, if Figure 7 and 9 As shown, the first positioning portion 13 is configured as a positioning groove, the second positioning portion 211 is configured as a positioning hole, and the third positioning portion 31 is configured as a positioning column protruding toward the direction of the support member 21. The positioning column passes through the positioning hole, and the positioning column is positioned and matched with the positioning groove. In other words, the first positioning portion 13 and the second positioning portion 211 can both be hole structures, and the third positioning portion 31 can be a columnar structure. The positioning column is set toward the direction of the support member 21. It should be noted that the third positioning portion 31 needs to pass through the second positioning portion 211 to match with the first positioning portion 13. Therefore, this setting is more reasonable and facilitates the third positioning portion 31 to match with the first positioning portion 13 and the second positioning portion 211. Specifically, when the connecting member 30 is assembled with the support member 21 and the housing 10, the positioning column protruding from the connecting member 30 will first match with the positioning hole. As the assembly proceeds, the positioning column will pass through the positioning hole to match with the positioning groove, so that the positioning column can match with the positioning groove and the positioning hole at the same time.
[0049] In addition, if Figure 3As shown, in the direction of the abutment of the connecting member 30, the positioning groove is aligned with the positioning hole. Since the positioning column cooperates with the positioning groove and the positioning hole at the same time, the positioning groove and the positioning hole are aligned, which makes it easy for the positioning column to cooperate with the positioning groove and the positioning hole at the same time. In addition, the positioning column only needs to be a long structure, which is simple in structure and convenient for processing and setting of the positioning column.
[0050] Furthermore, if Figure 3 As shown, the inner diameter of the positioning groove is d1, the inner diameter of the positioning hole is d2, the diameter of the positioning column is d3, and the relationship between d1, d2 and d3 is: d3≤d1≤1.2d3, d3≤d2≤1.2d3. In other words, the diameter of the positioning column and the inner diameter of the positioning groove need to meet a certain range. That is: the inner diameter of the positioning groove needs to be greater than or equal to the diameter of the positioning column, so that the positioning column and the positioning groove can be matched to avoid the situation where they cannot be installed. The inner diameter of the positioning groove also needs to be less than or equal to 1.2 times the diameter of the positioning column, so as to avoid the inner diameter of the positioning groove being too large, which will cause large shaking after the positioning column and the positioning groove are matched.
[0051] Similarly, the diameter of the positioning post and the inner diameter of the positioning hole need to meet a certain range. That is, the inner diameter of the positioning hole needs to be greater than or equal to the diameter of the positioning post, so that the positioning post and the positioning hole can be matched to avoid the situation where they cannot be installed. The inner diameter of the positioning hole also needs to be less than or equal to 1.2 times the diameter of the positioning post, so as to avoid the inner diameter of the positioning hole being too large, which will cause large shaking after the positioning post and the positioning slot are matched. Among them, the inner diameter of the positioning hole can be larger than the inner diameter of the positioning slot.
[0052] Specifically, Figure 8 As shown, there are two positioning posts, and the diameters of the two positioning posts are different; and / or the sizes of the two positioning posts protruding toward the support member 21 are different. Two positioning posts are set, so that when the sensor 1 is assembled, the connector 30 can be positioned with the support member 21 and the housing 10 at two positions, so that the installation accuracy and stability between the connector 30, the support member 21 and the housing 10 can be further improved. Moreover, the diameters of the two positioning posts are different, that is, the diameters of the two positioning posts can be different sizes, so that when the connector 30, the support member 21 and the housing 10 are matched, the two different positioning posts can play a better positioning and limiting role, can enhance the buckling degree between the connector 30 and the support member 21, and can improve the matching stability between the connector 30 and the support member 21. Alternatively, the sizes of the two positioning posts protruding in the direction toward the support member 21 are different, that is, the lengths of the two positioning posts are different, so that the two positioning posts can be set according to the actual working conditions, and the use is more flexible. Of course, the two positioning posts can have different diameters, different lengths, or different shapes.
[0053] In addition, if Figure 8 As shown, the cross section of the end of the connector 30 facing the support member 21 is circular, and the line connecting the centers of the two positioning posts is not colinear with the center of the cross section. Since the external shape of the support member 21 is circular, the connector 30 is constructed as a circular structure, which is convenient for the connector 30 to fit with the support member 21, and the circular structure is simple and easy to process and set. The line connecting the centers of the two positioning posts is not colinear with the center of the connector 30, which can prevent the connector 30 from rotating significantly after being connected to the support member 21, affecting the normal transmission of the signal on the connector 30.
[0054] In addition, if Figure 2 As shown, the connecting member 30 is also provided with a first clamping portion 32, and the supporting member 21 is also provided with a second clamping portion 212, and the second clamping portion 212 is clamped and matched with the first clamping portion 32. Among them, the first clamping portion 32 and the second clamping portion 212 can both play a clamping role. The first clamping portion 32 is arranged on the connecting member 30, and the second clamping portion 212 is arranged on the supporting member 21. In this way, when the connecting member 30 is assembled, the first clamping portion 32 and the second clamping portion 212 can cooperate to make the connection between the connecting member 30 and the supporting member 21 more stable.
[0055] Furthermore, if Figure 2 and Figure 3 As shown, the pressure sensing component 20 also includes a pressure sensing member 22, which is arranged on the support member 21, and the connecting member 30 abuts against the pressure sensing member 22, and the connecting member 30 is electrically connected to the pressure sensing member 22. Among them, the pressure sensing member 22 is mainly used to sense the pressure of the medium. The pressure sensing member 22 is arranged on the support member 21, so that the pressure sensing member 22 can be fixed, so that the setting of the pressure sensing member 22 is more reliable and stable, and the pressure sensing member 22 can work better. The connecting member 30 abuts against the pressure sensing member 22, so that the connecting member 30 can further press the pressure sensing member 22, so that the pressure sensing member 22 can be more stable. Moreover, the pressure sensing member 22 is located between the support member 21 and the connecting member 30, so that the pressure sensing member 22 can also be protected. The connecting member 30 is electrically connected to the pressure sensing member 22, that is, the pressure sensing member 22 can transmit the sensed medium pressure signal to the connecting member 30, and then the connecting member 30 can transmit it to the outside of the sensor 1.
[0056] Specifically, Figure 7As shown, the support member 21 is also provided with an abutting portion 213, and the abutting portion 213 abuts against the outer wall surface of the pressure sensing member 22. The abutting portion 213 mainly plays the role of abutment. The abutting portion 213 is provided on the support member 21, so that when the pressure sensing member 22 is connected to the support member 21, the abutting portion 213 can abut against the outer wall surface of the pressure sensing member 22, thereby making the connection between the pressure sensing member 22 and the support member 21 more reliable and stable, and the pressure sensing member 22 can work better.
[0057] In addition, if Figure 6 and Fig.10 As shown, the sensor 1 also includes a first connecting spring 40, which is electrically connected to the pressure sensing member 22. A connecting terminal 33 is also provided at one end of the connecting member 30 facing the supporting member 21. The connecting terminal 33 is electrically connected to the first connecting spring 40, and the connecting terminal 33 presses the first connecting spring 40. Among them, the first connecting spring 40 mainly plays the role of electrical connection. The first connecting spring 40 is electrically connected to the pressure sensing member 22, so that the medium pressure signal sensed by the pressure sensing member 22 can be input to the first connecting spring 40, thereby facilitating the transmission of subsequent signals. The connecting terminal 33 mainly plays the role of electrical connection. The connecting terminal 33 is electrically connected to the first connecting spring 40, so that the signal transmitted from the pressure sensing member 22 to the first connecting spring 40 will be transmitted to the connecting member 30 through the connecting terminal 33, and then the signal can be transmitted to the outside of the sensor 1. Since the connection terminal 33 is electrically connected to the first connection spring sheet 40, the connection terminal 33 is arranged on the side of the connection member 30 facing the support member 21. This arrangement is more reasonable and can shorten the distance between the connection terminal 33 and the first connection spring sheet 40, thereby facilitating electrical connection between the connection terminal 33 and the first connection spring sheet 40. Compared with welding, the connection method using the first connection spring sheet 40 is simpler and can reduce costs.
[0058] In addition, if Fig.10 As shown, the first connecting spring piece 40 includes a connecting portion 41, a contact portion 42 and a supporting portion 43. The connecting portion 41 is electrically connected to the pressure sensing element 22, the supporting portion 43 is connected to the connecting portion 41, the contact portion 42 is connected to the connecting portion 41, and the contact portion 42 is rotatably arranged on the supporting portion 43, and the connecting terminal 33 is electrically connected to the contact portion 42. Among them, the connecting portion 41 and the contact portion 42 both mainly play the role of electrical connection, and the supporting portion 43 can play the role of support and electrical connection. The connecting portion 41 is electrically connected to the pressure sensing element 22, so that the signal on the pressure sensing element 22 can be transmitted to the connecting portion 41. The supporting portion 43 is connected to the connecting portion 41, which can improve the stability of the connection between the connecting portion 41 and the supporting portion 43, and the supporting portion 43 can be used to support the connecting portion 41, so that the connection between the connecting portion 41 and the pressure sensing element 22 is more stable.
[0059] The contact portion 42 is connected to the connecting portion 41. It should be noted that the contact portion 42 and the connecting portion 41 are electrically connected, so that the signal transmitted from the pressure sensing element 22 to the connecting portion 41 is transmitted to the contact portion 42. Because the connecting terminal 33 is electrically connected to the contact portion 42, the signal transmitted to the contact portion 42 is further transmitted to the connecting terminal 33, and then transmitted to the outside by the connecting member 30.
[0060] The contact portion 42 is rotatably disposed on the support portion 43, that is, the contact portion 42 can rotate relative to the support portion 43. It should be noted that when the pressure sensing component 22 is press-fitted, the pressure sensing component 22 will be pre-installed first. During the pre-installation, the connection terminal 33 on the connector 30 will pre-press the contact portion 42, and the contact portion 42 will rotate relative to the support portion 43 under the pressure of the connection terminal 33, thereby ensuring that the connection terminal 33 and the contact portion 42 have good contact. After the pre-pressing is completed, formal pre-pressing will be performed, and the connection terminal 33 will further squeeze the contact portion 42, so that the contact portion 42 will further rotate relative to the support portion 43, thereby enabling the connection terminal 33 and the contact portion 42 to better cooperate.
[0061] Furthermore, if Fig.10 As shown, in the pressing direction of the connection terminal 33, the maximum distance between the connection terminal 33 and the connection part 41 is a, the maximum distance between the support part 43 and the connection part 41 is b, and the maximum distance between the contact part 42 and the connection part 41 is c. The relationship between a, b and c is: b<a<c. That is to say, in the pressing direction of the connection terminal 33, the maximum distance between the connection terminal 33 and the connection part 41 and the maximum distance between the support part 43 and the connection part 41, as well as the maximum distance between the connection terminal 33 and the connection part 41 and the maximum distance between the contact part 42 and the connection part 41 c need to meet a certain range, that is, the maximum distance between the connection terminal 33 and the connection part 41 needs to be greater than the maximum distance between the support part 43 and the connection part 41, so as to avoid the pressure sensing part 22 being damaged by excessive force during the press-fitting process. The maximum distance between the connection terminal 33 and the connection part 41 also needs to be less than the maximum distance between the contact part 42 and the connection part 41, so as to avoid the first connection spring 40 and the connection member 30 from having poor contact, resulting in the signal being unable to be transmitted normally.
[0062] Furthermore, if Figure 6 and Figure 7As shown, the sensor 1 also includes a second connecting spring piece 50, which is connected to the side of the pressure sensing member 22 adjacent to the support member 21, and the support member 21 is provided with a through hole 214, and the second connecting spring piece 50 passes through the through hole 214. Among them, the second connecting spring piece 50 mainly plays the role of electrical connection. The through hole 214 can play the role of positioning and installation. The second connecting spring piece 50 passes through the through hole 214, so that the through hole 214 has a positioning effect on the second connecting spring piece 50, which can improve the accuracy of the assembly of the pressure sensing member 22, and to a certain extent, it can also protect the second connecting spring piece 50. Therefore, the second connecting spring piece 50 is connected to the side of the pressure sensing member 22 adjacent to the support member 21. This setting is more reasonable and facilitates the cooperation between the second connecting spring piece 50 and the through hole 214. It should be noted that in order to make the sensor 1 work more safely, the sensor 1 needs to be grounded. Specifically, the second connecting spring piece 50 can be electrically connected to the housing 10 through the through hole 214, so that the grounding of the sensor 1 can be achieved.
[0063] In addition, if Figure 3 As shown, the sensor 1 also includes a temperature sensing component 60, which includes: a temperature sensing element 61, a protective cover 62 and a mounting base 63. One end of the mounting base 63 is matched with the protective cover 62, and the temperature sensing element 61 is connected to a side of the mounting base 63 adjacent to the protective cover 62, and the temperature sensing element 61 is arranged in the protective cover 62. Among them, the temperature sensing element 61 is mainly used to sense the temperature of the medium, and the temperature sensing element 61 can be an NTC thermistor. The protective cover 62 mainly plays a protective role. The mounting base 63 mainly plays a mounting role.
[0064] The temperature sensing element 61 is arranged in the protective sleeve 62, so that the protective sleeve 62 can be used to protect the temperature sensing element 61, and the medium can be prevented from directly impacting the temperature sensing element 61, so that the temperature sensing element 61 can work better. The temperature sensing element 61 is connected to the side of the mounting base 63 adjacent to the protective sleeve 62, so that the temperature sensing element 61 can be fixed, so that the setting of the temperature sensing element 61 is more reliable and stable, so that the temperature sensing element 61 can work better. It is also convenient for the temperature sensing element 61 to be installed and matched with the protective sleeve 62, and then it is convenient for the protective sleeve 62 to protect the temperature sensing element 61.
[0065] It should be noted that since the temperature sensing component 61 is installed on the mounting base 63, the mounting base 63 is matched with the protective cover 62. This arrangement is more reasonable. While achieving the installation and matching of the mounting base 63 and the protective cover 62, it is also convenient for the temperature sensing component 61 to match with the protective cover 62.
[0066] In addition, if Figure 5As shown, a first limiting portion 11 is provided on the housing 10, a second limiting portion 621 is provided on the protective sleeve 62, and a third limiting portion 631 is provided on the mounting base 63. The second limiting portion 621 and the third limiting portion 631 are respectively matched with the first limiting portion 11 for limiting. The first limiting portion 11, the second limiting portion 621 and the third limiting portion 631 can all play a limiting role. The first limiting portion 11 is provided on the housing 10, and the second limiting portion 621 is provided on the protective sleeve 62. In this way, when the protective sleeve 62 is installed with the housing 10, the first limiting portion 11 and the second limiting portion 621 cooperate to install more accurately, and the protective sleeve 62 can be prevented from rotating relative to the housing 10, so that the sensor 1 can work better. Similarly, the third limiting portion 631 is arranged on the mounting base 63, and the first limiting portion 11 is arranged on the shell 10. In this way, when the mounting base 63 and the shell 10 are installed, the first limiting portion 11 and the third limiting portion 631 cooperate to achieve more accurate installation and avoid the mounting base 63 from rotating relative to the shell 10, so that the sensor 1 can work better.
[0067] Furthermore, if Figure 5 As shown, in the axial direction of the protective sleeve 62, the second limiting portion 621 is aligned with the third limiting portion 631. As can be seen from the above, the second limiting portion 621 and the third limiting portion 631 are both matched with the first limiting portion 11, so in the axial direction of the protective sleeve 62, the second limiting portion 621 is aligned with the third limiting portion 631, so that the second limiting portion 621 and the third limiting portion 631 can be matched with the first limiting portion 11 at the same time, and after the second limiting portion 621 and the third limiting portion 631 are matched with the first limiting portion 11, the position between the protective sleeve 62 and the mounting base 63 can also be kept relatively stable, so that the temperature sensing component 60 can be kept relatively stable, and the sensor 1 can work better.
[0068] In addition, if Figure 3As shown, a step portion 12 is provided in the housing 10, and the protective sleeve 62 is also provided with a matching surface 622. In the first axial direction of the protective sleeve 62, the matching surface 622 is limitedly matched with the surface of the step portion 12. A protective member 632 is provided at one end of the mounting base 63 away from the protective sleeve 62. In the second axial direction of the protective sleeve 62, the protective member 632 is abutted against the pressure sensing member 22. The second axial direction of the protective sleeve 62 is opposite to the first axial direction of the protective sleeve 62. Among them, the step portion 12 and the matching surface 622 can both play a role in limiting. The step portion 12 is provided in the housing 10, and the matching surface 622 is provided on the protective sleeve 62. In this way, when the protective sleeve 62 is installed on the housing 10, the protective sleeve 62 can be limited in the axial direction of the protective sleeve 62 by using the matching of the step portion 12 and the matching surface 622, so that the installation of the protective sleeve 62 can be more accurate, the assembly efficiency is improved, and the setting of the protective sleeve 62 can also be made more stable.
[0069] The protective member 632 mainly plays a protective role. The protective member 632 is set at one end of the mounting base 63 away from the protective sleeve 62, so that in the second axial direction of the protective sleeve 62, the protective member 632 can abut against the pressure sensing member 22, so that the protective member 632 can be used to eliminate the gap between the pressure sensing member 22 and the mounting base 63, thereby avoiding a collision between the pressure sensing member 22 and the mounting base 63, thereby affecting the normal use of the sensor 1. It should be noted that the second axial direction of the protective sleeve 62 is opposite to the first axial direction of the protective sleeve 62. Specifically, the first axial direction of the protective sleeve 62 is the direction of the pressure sensing member 22 toward the protective sleeve 62, and the second axial direction of the protective sleeve 62 is the direction of the protective sleeve 62 toward the pressure sensing member 22.
[0070] In addition, if Figure 2 and Figure 3 As shown, the sensor 1 also includes a seal 70, which can be a sealing ring. The seal 70 is spaced apart from the mounting base 63, and the seal 70 is sealingly disposed between the pressure sensing component 22 and the housing 10. Among them, the seal 70 mainly plays a sealing role. It should be noted that the seal 70 is sleeved on the mounting base 63, so the seal 70 is spaced apart from the mounting base 63, that is, there is a gap between the seal 70 and the mounting base 63, which facilitates the installation of the seal 70. Moreover, the seal 70 is sealingly disposed between the pressure sensing component 22 and the housing 10, so that the seal 70 can seal the gap between the pressure sensing component 22 and the housing 10.
[0071] It should be noted that the seal 70 can separate the gap between the pressure sensing element 22 and the housing 10 into two areas, that is, the inside of the seal 70 is the medium contact area, and the outside of the seal 70 is the medium isolation area, and the third limit portion 631 is also a pressure inlet while limiting, and the medium can enter the medium contact area from the third limit portion 631, and then can perform contact sensing with the pressure sensing element 22. Specifically, when the sensor 1 measures the pressure of the medium, the medium can successively enter the medium contact area along the second limit portion 621 and the third limit portion 631 to perform contact sensing with the pressure sensing element 22, and the pressure sensing element 22 will transmit the corresponding signal to the connector 30 after sensing, and then output the signal to the outside of the sensor 1.
[0072] As an optional embodiment, the pressure sensing element 22 is a ceramic element. That is, the circuit board in the pressure sensing element 22 can be a ceramic circuit board, which can better prevent the sensor 1 from causing damage to the circuit board during installation compared to a flexible circuit board. Moreover, when the pressure sensing element 22 presses the sealing element 70, the ceramic material can better press the sealing element 70, thereby ensuring the sealing of the sensor 1.
