Description

Technical Field

[0001] The present application relates to the technical field of temperature detection equipment, and in particular to a thermocouple connector and a temperature measurement system. Background Art

[0002] A thermocouple is a temperature measuring element. During the measurement process, the measuring end of the thermocouple is placed at the position to be measured, and the reference end of the thermocouple is placed in a reference environment. The temperature of the reference environment and the electrical signal (such as a voltage signal) at the reference end of the thermocouple are measured by the temperature measurement system to calculate the temperature measurement value of the position to be measured.

[0003] In the related art, the temperature measurement system for thermocouples includes a measuring instrument and a connecting wire. During the measurement process, one end of the connecting wire is fixed to the reference end of the thermocouple by welding or similar means, and the other end of the connecting wire is connected to the measuring instrument. The measuring instrument obtains the electrical signal of the reference end of the thermocouple through the connecting wire.

[0004] However, in the related art, the connection operation between the connecting wire and the reference end of the thermocouple is cumbersome and complicated, which affects the measurement efficiency of the temperature measurement system for the thermocouple. Utility Model Content

[0005] The embodiments of the present application provide a thermocouple connector and a temperature measurement system, which can more easily realize a fixed connection between a connecting wire and a reference end of a thermocouple, thereby improving the measurement efficiency of the temperature measurement system for the thermocouple.

[0006] In a first aspect, an embodiment of the present application provides a thermocouple connector, comprising:

[0007] A test clamp, used to clamp the reference end of the thermocouple;

[0008] The connecting piece is arranged in the detection clamp, and when the detection clamp clamps the reference end, the connecting piece contacts and connects with the reference end;

[0009] A connecting wire has one end connected to the connecting piece and the other end used to be electrically connected to a measuring instrument to transmit the electrical signal at the reference end to the measuring instrument.

[0010] In one implementation, the connecting member is an elastic structure, and when the detection clamp clamps the reference end, the connecting member elastically abuts against the reference end.

[0011] In the implementation of the present application, through the connecting piece with an elastic structure, when detecting the reference end of the clamping teeth, the elastic force of the elastic structure can realize the abutment between the connecting piece and the reference end, thereby improving the connection stability between the connecting piece and the reference end.

[0012] In one implementation, the connecting member includes a first portion located at the front end of the detection clamp and a second portion located in the middle of the detection clamp. The first portion and the second portion have different elastic structures so that the first portion and the second portion are used to abut different reference ends.

[0013] In the implementation of the present application, by setting connecting pieces with different structures at different positions of the detection clamp, when facing different reference ends, the different positions of the detection clamp can be used for clamping, and elastic abutment can be achieved by connecting pieces with different structures, thereby improving the connection adaptability to different reference ends.

[0014] In one implementation, the detection clamp includes:

[0015] A first clamping body, wherein a front edge of the first clamping body is provided with first clamping teeth;

[0016] A second clamping body, the middle portion of which is hinged to the middle portion of the first clamping body, and the front portion of the second clamping body is provided with second clamping teeth;

[0017] The connecting member is fixed on the first clamping body and at least partially located inside the area surrounded by the first clamping teeth.

[0018] In the implementation of the present application, the reference end of the thermocouple can be clamped by the first clamping teeth and the second clamping teeth, and during this clamping process, a larger contact space can exist between the connecting piece and the reference end.

[0019] In one implementation, the connecting member includes a first portion located at the front end of the detection clamp, the first portion is a spring structure and is higher than a first clamping tooth on the front side of the first portion;

[0020] The elastic direction of the first part includes the occlusal direction of the first clamping teeth and the second clamping teeth. When the front end of the detection clamp clamps the reference end, the reference end is located between the first part and the second clamping body, and the elastic structure and the second clamping teeth are respectively in contact with two sides of the reference end.

[0021] The elastic direction of the first part includes a direction perpendicular to the occlusal direction. When the front end of the detection clamp clamps the reference end, the reference end is located between the first clamping teeth and the second clamping teeth, and the first part abuts against the rear end surface of the reference end.

[0022] In the implementation of the present application, a reference end with a larger shape can be clamped at the front end of the detection clamp. At this time, since the first part is a spring structure and is higher than the first clamping tooth at the front end of the detection clamp, the connection reliability between the reference end and the first part can be improved; further, according to different elastic directions, the first part can abut against different positions of the reference end, so that the first part can have better adaptability.

[0023] In one implementation, the connecting member includes a second portion located at a first position in the middle of the detection clamp, the second portion extends in the front-to-back direction, and at least partially is higher than the first clamping teeth on both sides of the second portion;

[0024] When the detection clamp clamps the reference end at the first position, the second part is in contact and connection with the reference end.

[0025] In the implementation of the present application, a reference end with a smaller shape, such as a linear shape, can be clamped in the middle of the detection clamp, and the extension direction of the second part can enable the detection clamp to clamp the reference end within a certain range without affecting the connection effect.

[0026] In one implementation, the connecting member includes a third portion located at a second position in the middle of the detection clamp, and the third portion forms a groove;

[0027] When the detection clamp clamps the reference end at the second position, the third part is in contact and connected with the reference end.

[0028] In the implementation of the present application, a reference end with an appropriate shape, such as a column, can be clamped in the middle of the detection clamp. The third part with a groove shape can reduce excessive deformation of the connecting piece when abutting the reference end, thereby increasing the service life of the connecting piece.

[0029] In one implementation, the first and second parts of the connector are integrally formed, and along the front-to-rear direction of the detection clamp, a portion of the third part of the connector is formed on the first part, and another portion of the third part is formed on the second part.

[0030] In the implementation of the present application, through the first part, the second part and the third part of the integrated structure, when the detection clamp can clamp the reference ends of different shapes, the connecting piece can provide an elastic structure matching therewith, thereby improving the universality of the thermocouple connector.

[0031] In one implementation, the thermocouple connector further includes a jacket:

[0032] The sleeve includes a sleeve and a handle. The sleeve is sleeved on the detection clamp. The head end of the handle is integrally connected with the tail end of the sleeve. The handle is a rigid part. The handle is provided with a cavity. One end of the detection clamp extends into the cavity of the handle and there is a distance between the end of the handle and the tail end of the handle. The handle is provided with a lead through hole, and the connecting wire is passed through the lead through hole.

[0033] In the implementation of the present application, through the structural design of the jacket, a protective extension structure can be provided for the detection clamp, which is more convenient for operation and use. The rigid structure can also provide protection for the connecting wire and the connection between the connecting wire and the connecting piece.

[0034] In one implementation, the detection clamp includes a first clamp body and a second clamp body that can be opened and closed with each other, the first clamp body has a first clamping surface, the second clamp body has a second clamping surface, and the first clamping surface and the second clamping surface are used to clamp the reference end;

[0035] The detection clamp also includes a force storage member, which is used to provide the first clamping surface and the second clamping surface with a force acting toward each other when the first clamping surface and the second clamping surface are opened, so that the first clamping surface and the second clamping surface have a tendency to close.

[0036] In the implementation of the present application, the clamping degree of the first clamping surface and the second clamping surface can be improved through the design of the force storage member, thereby improving the clamping stability of the reference end.

[0037] In one implementation, the force storage member includes a fastening elastic member;

[0038] One end of the fastening elastic member is connected to the first clamping body, and the other end of the fastening elastic member is connected to the second clamping body. When the first clamping surface and the second clamping surface are opened, the fastening elastic member is in a first compression state. When the first clamping surface and the second clamping surface are in contact, the fastening elastic member is in a second compression state. The elastic force in the first compression state is greater than the elastic force in the second compression state.

[0039] A force storage cavity is provided in the middle of the first clamp body, and a fastening elastic member is arranged in the force storage cavity. A bending portion is formed at one end of the second clamp body, and the bending portion bends toward the direction of the first clamp body. A second clamping surface is formed on a side of the bending portion facing the first clamp body, and a first clamping surface is formed on a side of the first clamp body facing the bending portion. The second clamp body passes through the force storage cavity, and a pushing portion is formed at the other end of the second clamp body. When the pushing portion is pushed toward the direction of the first clamp body, the first clamping surface and the second clamping surface open.

[0040] In the implementation of the present application, a clamp connection method that is different from the hinged method is provided, and the arrangement and working principle of the fastening elastic member are also different from the torsion spring. The push-control structure can meet the needs of the application scenario.

[0041] In one implementation, a mounting through hole is formed in the first clamp body, a portion of the connecting member is located between the first clamping surface and the second clamping surface, and is in contact and connection with the reference end when the detection clamp clamps the reference end;

[0042] Another part of the connecting piece is passed through the installation through hole and is connected with the connecting wire.

[0043] In the implementation of the present application, the through-hole is used to provide protection for the connector, and the connector led out from the through-hole can also be more conveniently arranged between the first clamping surface and the second clamping surface.

[0044] In one implementation, at least one of the first clip and the second clip is an insulating member.

[0045] In the implementation of the present application, the clamping body of the insulating member can reduce signal interference to the connecting member.

[0046] In one implementation, the detection clip and the connecting member are structural members made of different materials, so that the rigidity of the detection clip is greater than the rigidity of the connecting member;

[0047] The connecting member and the connecting line are structural members with the same Seebeck coefficient, and the Seebeck coefficient is the same as that of the reference end.

[0048] In the implementation of the present application, due to the separate structure of the detection clamp and the connector, different material structures can be selected for the two, so that the material structure of the connector meets the measurement requirements of the reference end, and the material structure of the detection clamp meets the clamping requirements. In a second aspect, an embodiment of the present application provides a temperature measurement system, including a measuring instrument and a thermocouple connector as described in any one of the first aspects;

[0049] The measuring instrument is electrically connected to the connecting line of the thermocouple connector to at least receive the electrical signal transmitted by the thermocouple connector and process it to obtain measurement information. In one implementation, the measuring instrument has a voltage measurement module and a signal interface, the voltage measurement module is electrically connected to the signal interface, and the voltage measurement module is used to measure the voltage value of the electrical signal;

[0050] The connecting wire is electrically connected to the signal interface to transmit the electrical signal;

[0051] There are at least two groups of signal interfaces and at least two voltage measurement modules. Different voltage measurement modules have different measurement accuracy. Different groups of signal interfaces are electrically connected to different voltage measurement modules.

[0052] In the implementation of the present application, by providing at least two voltage measurement modules and a signal interface in the measuring instrument, the measurement requirements of different thermocouples can be met.

[0053] The embodiment of the present application provides a thermocouple connector and a temperature measurement system. The connecting part is arranged in a detection clamp, and the reference end of the thermocouple is clamped by the detection clamp, so that the connecting piece arranged in the detection clamp can be in contact and connected with the reference end, so that the electrical signal of the reference end is transmitted to the measuring instrument through the connecting piece and the connecting wire, and the voltage value of the reference end is obtained. Compared with the related art of welding the connecting wire to the reference end, the embodiment of the present application can more easily realize the detachable fixed connection between the connecting wire and the reference end, thereby improving the measurement efficiency. In addition, the setting of the connecting piece in the detection clamp can consider the material of the connecting piece according to the transmission requirements of the electrical signal, and can consider the material of the detection clamp according to the clamping requirements. The material of the detection clamp can be different from that of the connecting piece, thereby making the manufacturing material of the thermocouple connector more flexible.

[0078] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0079] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific implementation methods disclosed below.

[0080] In the description of the present application, it should be understood that the terms "upper", "lower", "horizontal", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the present application, unless otherwise clearly specified and limited, a first feature being "upper" or "lower" than a second feature may be that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0081] In this application, unless otherwise clearly specified and limited, the terms "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected entities are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0082] In this application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0083] Figure 1 It is a schematic diagram of the structure of a thermocouple. Figure 1 As shown, the thermocouple 10 is an element that uses the Seebeck effect (also known as the first thermoelectric effect) to measure temperature. Generally, the thermocouple 10 includes a positive electrode part 12a and a negative electrode part 12b made of different materials. For example, the positive electrode part 12a of the platinum-rhodium 10-platinum thermocouple is a platinum-rhodium alloy containing 10% rhodium, and the negative electrode part 12b is pure platinum. One end of the positive electrode part 12a is in contact with one end of the negative electrode part 12b, and the contact connection end can also be called the measuring end 11 of the thermocouple 10. The other end of the positive electrode part 12a serves as the positive electrode of the reference end 12 of the thermocouple 10, and the other end of the negative electrode part 12b serves as the negative electrode of the reference end 12 of the thermocouple 10.

[0084] In the process of temperature measurement using the thermocouple 10, the measuring end 11 of the thermocouple 10 is set at the temperature point to be measured (i.e., the position to be measured), and the reference end 12 of the thermocouple 10 is set in the external environment. The reference end 12 of the thermocouple 10 will generate an electrical signal (e.g., a voltage signal). According to the Seebeck effect principle, the temperature difference between the measuring end 11 and the reference end 12 of the thermocouple 10 is proportional to the characteristic value of the electrical signal (e.g., the voltage value). Subsequently, if the temperature difference is determined, the characteristic value of the electrical signal can be detected. If the characteristic value of the electrical signal and the temperature of the reference end 12 are determined, the temperature of the measuring end 11 can be detected, that is, the temperature value of the position to be measured is determined.

[0085] In the related art, the temperature measurement system for the thermocouple 10 includes a measuring instrument and a connecting wire, one end of the connecting wire is welded to the reference end 12 of the thermocouple 10, and the other end of the connecting wire is connected to the measuring instrument. The measuring instrument obtains the voltage value of the reference end 12 of the thermocouple 10 through the connecting wire, and then calculates the above temperature difference according to the thermocouple coefficient of the thermocouple 10. In addition, the measuring instrument measures the ambient temperature to obtain the reference temperature.

[0086] However, before each measurement, the temperature measurement system needs to weld one end of the connecting wire to the reference end 12 of the thermocouple 10, which makes the connection operation between the connecting wire and the thermocouple 10 cumbersome and complicated, affecting the measurement efficiency of the temperature measurement system for the thermocouple.

[0087] In addition, after the measurement is completed, if the temperature measurement system continues to be used to measure other thermocouples 10, the welding position must be melted first before the connecting wire and the thermocouple reference end 12 can be removed, which makes the removal operation cumbersome and complicated, and may even cause damage to the connecting wire or the thermocouple reference end 12.

[0088] If the connection line of the temperature measurement system and the thermocouple 10 are not removed, the temperature measurement system is used in conjunction with the thermocouple 10, which causes the temperature measurement system to be unable to measure other different types of thermocouples 10, limiting the scope of use of the temperature measurement system.

[0089] The embodiment of the present application provides a thermocouple connector and a temperature measurement system. The connection part used to connect the reference end of the thermocouple in the thermocouple connector is set as a detection clamp, and the reference end of the thermocouple is clamped by the detection clamp to stabilize the reference end of the thermocouple on the thermocouple connector. Then, the connection piece set in the detection clamp is contacted and connected with the reference end, so that the electrical signal of the reference end is transmitted to the measuring instrument through the connection piece and the connection line to obtain the voltage value of the reference end. Compared with the related art in which the connection line is welded to the reference end, the embodiment of the present application simplifies the connection process between the thermocouple connector and the reference end of the thermocouple, improves the measurement efficiency, and can also quickly remove the thermocouple connector from the reference end, so that the thermocouple connector can measure other types of thermocouples. In addition, the setting of the connection piece in the detection clamp, on the one hand, realizes the transmission of the electrical signal of the reference end, and on the other hand, in order to accurately transmit the electrical signal to the measuring instrument, only the material of the connection piece needs to be considered. The material of the detection clamp can be different from that of the connection piece, thereby making the manufacturing material of the detection clamp more flexible.

[0090] The thermocouple connector and temperature measurement system provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0091] Figure 2 is a schematic diagram of the structure of a temperature measurement system provided in an embodiment of the present application, Figure 3 yes Figure 2 Schematic diagram of the structure of the thermocouple connector. Figure 4 It is a structural schematic diagram of a detection clamp and a connecting piece provided in one embodiment of the present application;

[0092] Figure 5 is a cross-sectional view of a detection clip and a connecting member provided in one embodiment of the present application, Figure 6 is a schematic diagram of the structure of a detection clamp provided in an embodiment of the present application, Figure 7 This is a schematic diagram of the structure of the detection clamp, the connecting piece and the reference end provided in one embodiment of the present application. Figure 1 . Reference Figures 2 to 7 As shown, an embodiment of the present application provides a temperature measurement system 20 , including a measuring instrument 200 and a thermocouple connector 100 .

[0093] The thermocouple connector 100 includes a detection clamp 110, which is used to clamp the reference end 12 of the thermocouple 10, for example, Figure 6 As shown, the detection clamp 110 includes a clamping portion 1111, and the clamping portion 1111 is provided with clamping teeth 1112. During the measurement process, the clamping portion 1111 of the detection clamp 110 clamps the reference end 12 of the thermocouple 10, and the clamping teeth 1112 on the clamping portion 1111 abut against the reference end 12, so that the reference end 12 of the thermocouple 10 is stably fixed in the detection clamp 110.

[0094] It should be noted that the clamping portion 1111 is disposed at the front portion of the detection clamp 110 and refers to a portion for clamping the reference end 12 of the thermocouple 10, and specifically refers to Figure 6 The part in the dotted box, that is, when the detection clamp 110 clamps the reference end 12, the part close to the outer periphery of the reference end 12 is the clamping portion 1111, that is, the part with the clamping function is the clamping portion 1111, and the part away from the outer periphery of the reference end 12 can be the holding portion, that is, the part without the clamping teeth 1112 is the holding portion, and the clamping portion 1111 can be driven by the holding portion to clamp the reference end 12 in the clamping portion 1111.

[0095] Reference Figures 4 to 6 As shown, in the embodiment of the present application, the detection clamp 110 may include a first clamp body 11a and a second clamp body 11b that are hinged. The first clamp body 11a and the second clamp body 11b are located on one side of the hinge point to form a clamping portion 1111.

[0096] For example, the hinge point may be located in the middle of the first clamp body 11a and the second clamp body 11b, that is, the middle of the first clamp body 11a and the second clamp body 11b may be hinged via a hinge structure 11c, wherein the hinge structure 11c may include a torsion spring, and the provision of the torsion spring may increase the clamping force of the front part of the first clamp body 11a and the second clamp body 11b, such as the clamping part 1111. It is understood that the hinge point refers to the location where the hinge structure 11c is provided.

[0097] Exemplarily, the first clamp body 11a and the second clamp body 11b are located on the other side of the hinge structure 11c to form a holding portion. By applying force to the holding portion, the clamping portion 1111 of the first clamp body 11a and the second clamp body 11b can be opened to allow the reference end 12 of the thermocouple 10 to enter the clamping portion 1111. By releasing the force on the holding portion, the clamping portion 1111 of the first clamp body 11a and the second clamp body 11b are closed, so that the clamping teeth 1112 on the clamping portion 1111 abut against the side wall of the reference end 12, so that the reference end 12 is stably clamped in the detection clamp 110.

[0098] Exemplarily, the clamping teeth 1112 may be provided on the first clamping body 11a, for example, the clamping teeth 1112 are provided at the front of the first clamping body 11a. In some examples, the clamping teeth 1112 may also be provided on the second clamping body 11b, for example, the clamping teeth 1112 are provided at the front of the second clamping body 11b. Of course, in other examples, the clamping teeth 1112 may be provided on both the first clamping body 11a and the second clamping body 11b, for example, the clamping teeth 1112 are provided at the front of the first clamping body 11a, and the clamping teeth 1112 are provided at the front of the second clamping body 11b, so that the clamping teeth 1112 on the upper and lower sides abut against the two sides of the reference end 12, thereby improving the stability of the clamping of the reference end 12 by the detection clamp 110.

[0099] For the convenience of description, the clamping teeth 1112 located on the first clamping body 11a can be called first clamping teeth 1112a, and the clamping teeth 1112 located on the second clamping body 11b can be called second clamping teeth 1112b. When the first clamping body 11a and the second clamping body 11b are adapted to be clamped, the first clamping teeth 1112a and the second clamping teeth 1112b are adapted to be engaged.

[0100] The clamping teeth 1112 can be arranged in at least one of the middle and the edge of the clamping portion 1111. Taking the first clamping teeth 1112a as an example, the first clamping teeth 1112a can be arranged in the middle of the first clamping body 11a, or around the edge of the first clamping body 11a. Of course, in some examples, the first clamping teeth 1112a can also be arranged in the middle and the edge of the first clamping body 11a.

[0101] The embodiment of the present application configures the thermocouple connector 100 to include a detection clamp 110, and the reference end 12 is clamped by the clamping portion 1111 of the detection clamp 110. On the one hand, the stability of the reference end 12 on the thermocouple connector 100 can be ensured. On the other hand, compared with the related art in which the connecting wire is welded to the reference end 12, the embodiment of the present application simplifies the connection process between the thermocouple connector 100 and the thermocouple reference end 12, improves the measurement efficiency, and realizes a detachable connection between the thermocouple connector 100 and the reference end 12. For example, after the measurement is completed, the thermocouple connector 100 can be quickly removed from the reference end 12, so that the thermocouple connector 100 can measure other types of thermocouples 10, thereby improving the applicability of the thermocouple connector 100.

[0102] Figure 8 This is the structure diagram of the thermocouple reference end. Figure 1 , Fig. 9 This is a schematic diagram of the structure of the detection clamp, the connecting piece and the reference end provided in one embodiment of the present application. Figure 2 , Fig.10 This is the structure diagram of the thermocouple reference end. Figure 2 , Fig.11 This is a schematic diagram of the structure of the detection clamp, the connecting piece and the reference end provided in one embodiment of the present application. Figure 3 . Reference Figures 7 to 11 As shown, in practice, the reference end 12 of the thermocouple 10 may include three structural types: a screw head structure 122 , a lead structure 121 , and a stud structure 123 . The detection clip 110 may be applicable to at least these three types of reference ends 12 .

[0103] Reference Fig. 9As shown, for example, when the reference end 12 of the thermocouple 10 is a screw head structure 122, the screw head structure 122 is mainly engaged by the clamping teeth 1112 at the front end of the detection clamp 110. For example, when the detection clamp 110 is clamped and connected to the reference end 12 of the screw head structure 122, the first clamping teeth 1112a and the second clamping teeth 1112b located at the front end of the detection clamp 110 are respectively engaged on both sides of the screw head structure 122.

[0104] Reference Figure 7 and Fig.11 As shown, when the reference end 12 of the thermocouple 10 is a lead structure 121 or a stud structure 123, the side wall of the lead structure 121 or the stud structure 123 is mainly bitten by the clamping teeth 1112 at the front or middle part of the detection clamp 110. For example, when the detection clamp 110 is clamped and connected to the reference end 12 of the lead structure 121, the lead structure 121 can be bitten between the first clamping tooth 1112a and the second clamping tooth 1112b at the front or middle part of the detection clamp 110.

[0105] It should be noted that the front end of the detection clip 110 refers to the front end of the clamping portion 1111 away from the gripping portion. The front part of the detection clip 110 refers to the part of the clamping portion 1111 close to the front end, and the middle part refers to the part of the detection clip 110 close to the hinge structure 11c or the part below the hinge structure 11c.

[0106] In addition, when either the thermocouple connector 100 or the thermocouple 10 is damaged, only the damaged portion can be replaced without replacing the assembly of the thermocouple connector 100 and the thermocouple 10 , thereby saving maintenance costs.

[0107] Reference Figures 4 to 11 As shown, the thermocouple connector 100 of the embodiment of the present application also includes a connector 140 and a connecting wire 120, wherein the connector 140 is arranged in the detection clamp 110, and when the detection clamp 110 clamps the reference end 12, the connector 140 contacts and connects with the reference end so that the electrical signal of the reference end is transmitted to the connector 140.

[0108] In addition, one end of the connecting wire 120 is connected to the connecting member 140, and the other end is electrically connected to the measuring instrument 200 to transmit the electrical signal of the reference end 12 to the measuring instrument 200. The measuring instrument 200 is electrically connected to the connecting member 140 through the connecting wire 120 to receive the electrical signal on the reference end 12. The measuring instrument 200 processes the voltage value of the electrical signal transmitted by the connecting member 140 and the connecting wire 120, and obtains the temperature difference between the measuring end 11 and the reference end 12 of the thermocouple 10 based on the thermocouple coefficient, and then measures the temperature of the reference end 12 to finally obtain the temperature value of the position to be measured.

[0109] In some examples, the connecting member 140 may be disposed on the clamping portion 1111 of the detection clamp 110 and staggered with the clamping teeth 1112 .

[0110] For example, when the clamping portion 1111 clamps the reference end 12 of the thermocouple 10, the connector 140 located on the clamping portion 1111 contacts and connects with the reference end 12 to transmit the electrical signal of the reference end 12, and the measuring instrument 200 is electrically connected to the connector 140 through the connecting wire 120 to receive the electrical signal transmitted by the connector 140, that is, the electrical signal of the reference end 12 is transmitted to the measuring instrument 200 through the connector 140 and the connecting wire 120.

[0111] In the embodiment of the present application, the setting of the connecting member 140 in the detection clamp 110, on the one hand, realizes the transmission of the electrical signal to the reference end 12, and on the other hand, in order to accurately transmit the electrical signal to the measuring instrument 200, only the material of the connecting member 140 needs to be considered. The material of the detection clamp 110 can be different from that of the connecting member 140, thereby making the manufacturing material of the detection clamp 110 more flexible.

[0112] For example, during manufacturing, compared with setting the detection clamp as a structural member with the same Seebeck coefficient as the reference end, only the smaller connector 140 can be set as a structural member with the same Seebeck coefficient as the reference end 12. On the one hand, the manufacturing cost of the thermocouple connector 100 can be saved, and on the other hand, the contact potential difference between the connector 140 and the reference end 12 can be reduced, so that the electrical signal of the reference end 12, such as the voltage value, can be more accurately transmitted to the connector 140, thereby improving the measurement accuracy of the thermocouple 10.

[0113] In some examples, the connector 140 and the connecting wire 120 can be structural members with the same Seebeck coefficient. In this way, the contact potential difference between the connector 140 and the connecting wire 120 can be reduced, so that the voltage value on the reference terminal 12 can be accurately transmitted to the measuring instrument 200 via the connector 140 and the connecting wire 120, thereby obtaining a more accurate voltage measurement value.

[0114] On the other hand, the connector 140 and even the subsequent connecting wire 120 can be used as a compensation wire of the thermocouple. By extending the reference end of the thermocouple to the measuring instrument through the compensation wire, the temperature of the reference end can be measured by the temperature measurement module in the measuring instrument.

[0115] For example, the connecting member 140 and the connecting wire 120 may be platinum-rhodium parts, that is, the connecting member 140 and the connecting wire 120 are made of platinum-rhodium material.

[0116] In addition, the rigidity of the detection clamp 110 can be set to be greater than the rigidity of the connector 140. In this way, the structural strength of the detection clamp 110 can be enhanced, so that the detection clamp 110 can clamp the reference end 12 more firmly, thereby ensuring the contact stability between the connector 140 and the reference end 12, thereby more stably obtaining the electrical signal of the reference end 12.

[0117] For example, the detection clip 110 can be other metal parts, alloy parts or plastic parts other than relatively expensive metal parts such as platinum and rhodium. It only needs to ensure that the rigidity of the detection clip 110 meets the clamping requirements. The embodiment of the present application does not specifically limit the material of the detection clip 110.

[0118] In some examples, the thermocouple connector 100 may include two detection clips 110 , each detection clip 110 having a corresponding connection member 140 and a connection wire 120 therein.

[0119] The clamping portion 1111 of one of the detection clamps 110 is used to clamp the positive electrode portion 12a of the reference end 12 of the thermocouple 10 to secure the positive electrode portion 12a of the reference end 12 on the detection clamp 110. The connecting piece 140 located in the detection clamp 110 is in contact and connected with the positive electrode portion 12a to transmit the electromotive force of the positive electrode portion 12a of the reference end 12 to the measuring instrument 200.

[0120] The clamping portion 1111 of another detection clamp 110 is used to clamp the negative electrode portion 12b of the reference end 12 of the thermocouple 10 to secure the negative electrode portion 12b of the reference end 12 on the detection clamp 110. The connecting piece 140 located in the detection clamp 110 is in contact and connected with the negative electrode portion 12b to transmit the electromotive force of the negative electrode portion 12b of the reference end 12 to the measuring instrument 200.

[0121] The measuring instrument 200 processes the electromotive force of the negative electrode portion 12 b and the electromotive force of the positive electrode portion 12 a to calculate the temperature difference between the measuring end 11 and the reference end 12 of the thermocouple 10 .

[0122] Reference Figure 2 and Figure 3 As shown, for the convenience of description, the detection clamp 110 used to clamp the positive pole of the reference end 12 is called the first detection clamp 110a, the connecting member 140 located in the first detection clamp 110a is the first connecting member, and the connecting line 120 connected to the first connecting member is the first connecting line 120a; the detection clamp 110 used to clamp the negative pole of the reference end 12 is called the second detection clamp 110b, the connecting member 140 located in the second detection clamp 110b is the second connecting member 140b, and the connecting line 120 connected to the second connecting member 140b is the second connecting line 120b.

[0123] Reference Figure 5 and Figure 6As shown, at least one detection clamp 110, for example, the first detection clamp 110a, includes a clamping portion 1111, and the clamping portion 1111 is provided with clamping teeth 1112. During the measurement process, the clamping portion 1111 of the first detection clamp 110a clamps the positive portion 12a of the reference end 12, and the first connecting member located in the clamping portion 1111 contacts the positive portion 12a, so that the electrical signal of the positive portion 12a of the reference end 12 is stably transmitted to the first connecting member, and then transmitted to the measuring instrument 200 through the first connecting line 120a.

[0124] Similarly, the second detection clamp 110b includes a clamping portion 1111, and the clamping portion 1111 is provided with a clamping tooth 1112. During the measurement process, the clamping portion 1111 of the second detection clamp 110b clamps the negative portion 12b of the reference end 12, and the second connecting member 140b located on the clamping portion 1111 abuts against the negative portion 12b, so that the electrical signal of the negative portion 12b of the reference end 12 is stably transmitted to the second connecting member 140b, and then transmitted to the measuring instrument 200 through the second connecting line 120b.

[0125] It is understandable that the structure of the second detection clip 110b can be consistent with that of the first detection clip 110a. For details, reference can be made to the clamp body structure setting method of the first detection clip 110a mentioned above, which will not be repeated here.

[0126] The measuring instrument 200 processes the electromotive force of the positive portion 12 a and the electromotive force of the negative portion 12 b of the reference end 12 , and calculates the temperature difference between the measuring end 11 and the reference end 12 of the thermocouple 10 based on the thermocouple coefficient.

[0127] When the connecting member 140 is specifically set, it can be staggered with the clamping teeth 1112 of the clamping portion 1111. For example, the connecting member 140 and the clamping teeth 1112 are staggered in the occlusal direction of the clamping portion 1111 to avoid the connecting member 140 being squeezed and damaged by the reference end 12 and the clamping teeth 1112 when the clamping teeth 1112 of the clamping portion 1111 are clamped and abutted against the reference end 12. In addition, it also avoids the connecting member 140 from interfering with the clamping teeth 1112 abutting against the reference end 12, ensuring that the clamping teeth 1112 can be in stable contact with the reference end 12.

[0128] For example, the connecting member 140 can be spaced apart from the clamping teeth 1112 along the first direction, or can be spaced apart from each other along the second direction. The first direction and the second direction are both perpendicular to the occlusal direction of the clamping portion 1111. For example, the first direction is the length direction of the clamping portion 1111 (refer to Figure 4 The second direction is the width direction of the clamping portion 1111 (refer to Figure 5 The y direction of the clamping portion 1111 can be referred to as Figure 4 and Figure 5 Shown in the z direction.

[0129] In some examples, when the clamping teeth 1112 are located at the edge of the clamping portion 1111 , the connector 140 may be located inside the area enclosed by the clamping teeth 1112 . In this way, the connector 140 may be set at any position inside the area enclosed by the clamping teeth 1112 without interfering with the clamping teeth 1112 .

[0130] Exemplarily, the connecting member 140 is disposed on any one of the two clamping bodies, for example, the connecting member 140 is disposed on the first clamping body 11a, and is staggered with the clamping teeth 1112, for example, the first clamping teeth 1112a, for example, the first clamping teeth 1112a are disposed at the edge of the first clamping body 11a, and the connecting member 140 is disposed inside the area surrounded by the clamping teeth 1112. In this way, when the first clamping body 11a and the second clamping body 11b are opened or closed, the connecting member 140 can move away from or toward the second clamping body 11b with the first clamping body 11a without affecting its own structural stability, and in addition, the stability of the connecting member 140 in the clamping portion 1111 can be ensured.

[0131] In some implementations, the connector 140 can be an elastic structure. When the detection clamp 110 clamps the reference end 12, the connector 140 elastically abuts against the reference end 12 to improve the contact tightness between the connector 140 and the reference end 12, so that the electrical signal on the reference end 12 can be transmitted to the connector 140 more stably.

[0132] Taking the example of the connecting member 140 being arranged on the first clamping body 11a, the height of the connecting member 140 can be higher than the height of the first clamping tooth 1112a, that is, at least part of the top surface of the connecting member 140 is higher than the tooth tip of the first clamping tooth 1112a. In this way, when the clamping portion 1111 clamps the reference end 12, the tooth tip of the first clamping tooth 1112a abuts against the surface of the reference end 12, and at least part of the top surface of the connecting member 140 will be pressed down by the resistance of the reference end 12, so that the top surface of the connecting member 140 is tightly abutted against the surface of the reference end 12, which is convenient for transmitting the electrical signal of the reference end 12.

[0133] When setting, at least part of the connecting member 140 can be set as a spring, a spring sheet or other similar elastic structure that can reflect the elasticity of the material. The embodiment of the present application does not specifically limit the way in which the connecting member 140 is set to be elastic.

[0134] It should be noted that, unlike the elasticity of a general material surface, an elastic structure means that there is a variation space in the direction of elastic deformation, so that the connector 140 as an elastic structure can be deformed in the elastic direction and stably abut against the reference end 12.

[0135] In addition, by configuring the connecting member 140 as an elastic structure, the connecting member 140 can play a certain clamping and stabilizing role on the reference end 12 , thereby further improving the stability of the reference end 12 in the detection clamp 110 .

[0136] Fig.12 2 is a cross-sectional view of a detection clip and another connecting member provided in one embodiment of the present application. Fig. 9 and Fig.12 As shown, as one of the settings, the connecting member 140 may include a first portion 141 located at the front end of the detection clamp 110, and the first portion 141 is a spring structure such as a spring, and is higher than the height of the clamping tooth 1112a. Taking the example of the connecting member 140 being set on the first clamp body 11a, the first portion 141 is higher than the height of the first clamping tooth 1112a at the front end of the first clamp body 11a.

[0137] For example, one end (e.g., the first end) of the first portion 141 is connected to the first clamp body 11a, and the other end (e.g., the second end) extends toward the second clamp body 11b. The extension direction of the first portion 141 may be parallel to the occlusal direction, or may have a certain angle with the occlusal direction, i.e., the second end of the first portion 141 extends obliquely upward, and the oblique direction may be toward the outside of the detection clip 110, i.e., the distance between the first end of the first portion 141 and the front end of the detection clip 110 is greater than the distance between the second end of the first portion 141 and the front end of the detection clip 110.

[0138] It should be noted that the front end of the detection clamp 110 refers to the frontmost part of the detection clamp 110 used for clamping the reference end 12 , that is, the front end of the clamping portion 1111 .

[0139] In some examples, the elastic direction of the first portion 141 includes the occlusal direction of the first clamping teeth 1112a and the second clamping teeth 1112b, referring to Fig. 9 and Fig.12 As shown in the z direction, when the front end of the detection clamp 110 clamps the reference end 12 , the reference end 12 is located between the first portion 141 and the second clamp body 11 b , and the elastic structure and the second clamping teeth 1112 b abut against two sides of the reference end 12 .

[0140] In this example, there is a certain angle between the extension direction of the first part 141 and the occlusal direction, such as an acute angle, that is, the second end of the first part 141 extends upward at an angle, so that the reference end 12 can more smoothly squeeze the second end of the first part 141 to its lower side.

[0141] For example, the reference end 12 is a screw head structure 122. When the detection clamp 110 clamps the screw head structure 122, the two side walls of the screw head structure 122 close to the rear end surface 122a can be clamped by the front ends of the first clamp body 11a and the second clamp body 11b. When the screw head structure 122 enters between the front ends of the first clamp body 11a and the second clamp body 11b, the first part 141 located at the front end is squeezed downward by the screw head structure 122, so that the screw head structure 122 is clamped between the first part 141 and the second clamping tooth 1112b at the front end of the second clamp body 11b.

[0142] It is understandable that when the front end of the detection clamp 110 clamps the screw head structure 122, the top surface of the first portion 141 abuts against the side wall of the screw head structure 122 to stably contact the screw head structure 122. In this example, the first portion 141 of the connecting member 140 can play a stabilizing role in clamping the reference end 12 and improve the clamping stability.

[0143] In addition, the front end of the detection clamp 110 is suitable for clamping a reference end 12 with a larger radial dimension. When clamping such a reference end 12, the reference end 12 does not need to extend into the middle of the detection clamp 110, thereby reducing the impact on the structural stability of the detection clamp 110. The setting of the above-mentioned first part 141 can ensure the stability of clamping such a reference end 12.

[0144] In some other examples, the elastic direction of the first portion 141 may include a direction perpendicular to the occlusal direction, for example, Fig. 9 and Fig.12 As shown in the x direction, when the front end of the detection clamp 110 clamps the reference end 12 , the reference end 12 is located between the first clamping teeth 1112 a and the second clamping teeth 1112 b , and the first portion 141 abuts against the rear end surface 122 a of the reference end 12 .

[0145] In this example, the extension direction of the first portion 141 may be parallel to the occlusal direction, that is, the first portion 141 extends vertically upward. Of course, the second end of the first portion 141 may also extend upwardly at an angle, so that the reference end 12 can press the first portion 141 backward.

[0146] Continuing with the example of the reference end 12 being the screw head structure 122, when the detection clamp 110 clamps the screw head structure 122, the clamping teeth 1112 at the front end of the detection clamp 110 can clamp the two side walls of the screw head structure 122 close to the rear end face, wherein, when the screw head structure 122 enters between the front ends of the first clamp body 11a and the second clamp body 11b, the first portion 141 located at the front end is pushed by the screw head structure 122 and compressed backwards, so that the screw head structure 122 is clamped between the first clamping teeth 1112a and the second clamping teeth 1112b at the front end, the first portion 141 is pushed to the rear of the screw head structure 122, and the front end of the first portion 141 abuts against the rear end face of the screw head structure 122.

[0147] It can be understood that the rear end of the screw head structure 122 refers to the end of the screw head structure 122 facing the detection clamp 110, and the backward movement of the first part 141 refers to movement along the x direction. The screw head structure 122 is clamped between the first clamping teeth 1112a and the second clamping teeth 1112b at the front end to ensure the stability of the screw head structure 122 in the detection clamp 110, and the first part 141 is pushed to the rear of the screw head structure 122 and abuts against the rear end surface of the screw head structure 122 to improve the contact tightness between the first part 141 and the screw head structure 122, so that the electrical signal on the screw head structure 122 can be more stably transmitted to the first part 141.

[0148] Of course, in this example, the front end of the detection clamp 110 can also clamp the reference end 12 of the stud structure 123 or the lead structure 121, which is similar to the way of clamping the screw head structure 122 and will not be repeated here.

[0149] Reference Figure 7 and Fig.12 As shown in FIG. 1 , as another configuration, the connecting member 140 may include a second portion 142 located in the middle of the detection clip 110, and the second portion 142 is arranged along the front-to-back direction (refer to FIG. 1 ). Fig.12 The second portion 142 extends in the x direction and is at least partially higher than the clamping teeth 1112 on both sides of the second portion 142.

[0150] Continuing with the example that the connecting member 140 is located on the first clamp body 11a, the second portion 142 of the connecting member 140 is located in the middle of the detection clamp 110, for example, between the hinge point and the front end of the detection clamp 110, and extends along the front-to-back direction, i.e., the length direction, and at least a portion of the second portion 142 is higher than the first clamp teeth 1112a on both sides. For example, the top surface of the second portion 142 protrudes from the tooth tips of the first clamp teeth 1112a on both sides.

[0151] It should be noted that the two sides of the second portion 142 refer to the two sides of the second portion 142 along the y direction which is perpendicular to the front-rear direction.

[0152] Exemplarily, the second portion 142 is disposed at a first position in the middle of the detection clamp 110 , and when the detection clamp clamps the reference end 12 at the first position, the second portion 142 is in contact and connected with the reference end 12 .

[0153] The elastic direction of the second portion 142 is the occlusal direction of the first clamping teeth 1112a and the second clamping teeth 1112b. Fig.12 As shown in the z direction, when the detection clamp 110 clamps the reference end 12, the reference end 12 may be located between a first position in the middle of the first clamp body 11a and the second clamp body 11b.

[0154] In this example, the reference end 12 may be a lead structure 121 or a stud structure 123 , that is, the first position of the detection clamp 110 may clamp the reference end 12 of the lead structure 121 or the stud structure 123 .

[0155] In some examples, when the reference end 12 is located between the first clamp body 11a and the first position in the middle of the second clamp body 11b, the first clamping teeth 1112a and the second clamping teeth 1112b on both sides of the first position can be clamped on both sides of the reference end 12 respectively, and the second portion 142 is compressed downward under the pressure of the reference end 12, so that the top surface of the second portion 142 abuts against the side wall of the reference end 12.

[0156] For example, the reference end 12 is a lead structure 121. When the detection clamp 110 clamps the lead structure 121, the upper and lower side walls of the lead structure 121 can be clamped by the first clamping teeth 1112a and the second clamping teeth 1112b on both sides of the first position of the first clamp body 11a and the second clamp body 11b. When the lead structure 121 enters between the first positions of the first clamp body 11a and the second clamp body 11b, the second part 142 located at the first position is squeezed downward by the lead structure 121, so that the top surface of the second part 142 abuts against the side wall of the reference end 12, thereby being able to stably transmit the electrical signal on the reference end 12 to the second part 142.

[0157] It is understandable that when the detection clamp 110 clamps the lead structure 121 at the first position, the top surface of the first portion 141 abuts against the side wall of the lead structure 121 , which can also play a role in clamping and stabilizing the reference end 12 .

[0158] In some other examples, when the reference end 12 is located between the first clamp body 11a and the first position in the middle of the second clamp body 11b, the second portion 142 and the second clamping tooth 1112b at the first position can be clamped on the upper and lower sides of the reference end 12 respectively to fix the reference end 12, and the first clamping tooth 1112a does not need to contact the reference end 12.

[0159] For example, when the detection clamp 110 clamps the lead structure 121, when the lead structure 121 enters between the first position of the first clamp body 11a and the second clamp body 11b, the second portion 142 located at the first position is squeezed downward by the lead structure 121, so that the top surface of the second portion 142 abuts against the lower side wall of the reference end 12. When the first clamp body 11a and the second clamp body 11b are closed, the second clamping teeth 1112b can clamp the upper side wall of the lead structure 121, so that the reference end 12 can be stably clamped between the second portion 142 and the second clamping teeth 1112b. In addition, the electrical signal of the reference end 12 can also be stably transmitted to the second portion 142. In this way, it is not necessary to set the first clamping teeth 1112a on the first clamp body 11a, thereby simplifying the structure of the detection clamp 110 and reducing the manufacturing cost of the detection clamp 110.

[0160] In the above example, the first position in the middle of the detection clamp 110 is suitable for clamping the reference end 12 with a smaller radial dimension. For example, the radial dimension of the lead structure 121 can be smaller than the distance between two adjacent tooth tips in the clamping teeth. In this way, the lead structure 121 can be inserted between the adjacent tooth tips of at least one of the first clamping tooth 1112a and the second clamping tooth 1112b, thereby limiting the lead structure 121 along the front-to-back direction and preventing the lead structure 121 from escaping from the detection clamp 110 along the front-to-back direction.

[0161] When the second part 142 is specifically configured, the end thereof facing the front end of the detection clip 110 (i.e., the third end) may be lower than the end facing away from the front end of the detection clip 110 (i.e., the fourth end), so that the top surface of the second part 142 is an inclined surface facing the front end of the detection clip 110. In this way, it is convenient for the reference end 12 to move from the third end of the second part 142 to the inclined surface, i.e., the top surface of the second part 142.

[0162] Reference Fig.10 , Fig.11 and Fig.12 As shown, as another setting mode, the connecting member 140 may include a third portion 143 located at a second position in the middle of the detection clamp 110, and the third portion 143 forms a groove. When the detection clamp clamps the reference end at the second position, the third portion contacts and connects with the reference end.

[0163] Continuing with the example of the connection member 140 being located on the first clamp body 11 a , the third portion 143 of the connection member 140 is located at a second position in the middle of the first clamp body 11 a , and the second position may be located in front of the first position or behind the first position.

[0164] In this example, the reference end 12 can be a structure with a radial dimension between the lead structure 121 and the screw head structure 122, such as a stud structure 123, and the radial dimension of the stud structure 123 is greater than the distance between two adjacent tooth tips in the clamping tooth 1112, so that when the stud structure 123 abuts against the clamping tooth 1112, it can abut against at least two tooth tips, that is, the stud structure 123 cannot be embedded in the recess between adjacent tooth tips. In the embodiment of the present application, the third part 143 is formed into a groove, and when the second position of the detection clamp 110 clamps the reference end 12 of the stud structure 123, the stud structure 123 can be embedded in the inner cavity of the groove of the third part 143 to limit the movement of the stud structure 123 in the front-to-back direction, thereby preventing the reference end 12 of the stud structure 123 from escaping from the front-to-back direction of the detection clamp 110.

[0165] In some examples, when the reference end 12, such as the stud structure 123, is located between the second position in the middle of the first clamp body 11a and the second clamp body 11b, the first clamping teeth 1112a and the second clamping teeth 1112b on both sides of the second position can be clamped on both sides of the stud structure 123, respectively, and the stud structure 123 is embedded in the groove of the third part 143 and contacts the side wall of the groove.

[0166] For example, when the detection clamp 110 clamps the stud structure 123, the upper and lower side walls of the stud structure 123 can be clamped by the first clamping teeth 1112a and the second clamping teeth 1112b on both sides of the second position of the first clamp body 11a and the second clamp body 11b, wherein when the stud structure 123 enters between the second positions of the first clamp body 11a and the second clamp body 11b, the third part 143 located at the second position is located below the stud structure 123, and the stud structure 123 is embedded in the groove of the third part 143 and contacts with at least part of the inner wall of the groove.

[0167] In this example, in the natural state, that is, when the detection clamp 110 does not clamp the reference end 12, at least part of the inner wall of the groove may be flush with or higher than the tooth tip of the first clamping tooth 1112a, so that when the tooth tip of the first clamping tooth 1112a abuts against the lower side wall of the stud structure 123, the inner wall of the groove contacts the lower side wall of the stud structure 123. For example, the inner bottom wall of the groove may be higher than the tooth tip of the first clamping tooth 1112a, so that when the stud structure 123 enters the second position between the first clamp body 11a and the second clamp body 11b, the stud structure 123 may contact the inner bottom wall of the groove, and when the first clamping tooth 1112a and the second clamping tooth 1112b engage the stud structure 123, the stud structure 123 may squeeze the inner bottom wall of the groove, so that the groove moves downward and abuts tightly against the lower side wall of the stud structure 123.

[0168] It can be understood that, in this example, the depth of the groove can be equal to or greater than the height of the clamping tooth 1112, such as the first clamping tooth 1112a, that is, the distance between the tooth root and the tooth tip of the first clamping tooth 1112a, so that when the first clamping tooth 1112a and the second clamping tooth 1112b engage the stud structure 123, the groove can be lower than the tooth tip of the first clamping tooth 1112a, so that the stud structure 123 can be located in the groove.

[0169] In some other examples, when the stud structure 123 is located between the first clamp body 11a and the second position in the middle of the second clamp body 11b, the third portion 143 and the second clamping tooth 1112b at the second position can be clamped on the upper and lower sides of the stud structure 123 respectively to fix the stud structure 123, and the first clamping tooth 1112a does not need to contact the stud structure 123.

[0170] For example, when the detection clamp 110 clamps the stud structure 123, when the stud structure 123 enters between the second position of the first clamp body 11a and the second clamp body 11b, the third part 143 located at the second position is squeezed by the stud structure 123 and compressed downward, so that the inner wall of the groove of the third part 143 abuts against the lower side wall of the stud structure 123. When the first clamp body 11a and the second clamp body 11b are closed, the second clamping teeth 1112b can clamp the upper side wall of the stud structure 123, so that the stud structure 123 can be stably clamped between the third part 143 and the second clamping teeth 1112b. In addition, the electrical signal of the stud structure 123 can also be stably transmitted to the third part 143.

[0171] In this example, in a natural state, at least part of the inner wall of the groove may be higher than the tooth tip of the first clamping tooth 1112a, so that when the stud structure 123 enters between the second position of the first clamping body 11a and the second clamping body 11b, it can squeeze the groove downward to abut against the inner wall of the groove. In addition, when the first clamping tooth 1112a and the second clamping tooth 1112b engage the stud structure 123, the inner wall of the groove, such as the inner bottom wall, may be higher than the tooth tip of the first clamping tooth 1112a, so that the stud structure 123 is clamped between the inner wall of the groove and the second clamping tooth 1112b without acting on the first clamping tooth 1112a. In this way, there is no need to set the first clamping tooth 1112a on the first clamping body 11a, thereby simplifying the structure of the detection clamp 110 and reducing the manufacturing cost of the detection clamp 110.

[0172] When setting, the groove of the third part 143 can be a U-shaped groove, that is, the longitudinal cross-section shape is U-shaped. In this way, the screw head structure 122 can be stably embedded in the U-shaped groove and contact both side walls and the inner bottom wall of the U-shaped groove to increase the contact area between the connector 140 and the stud structure 123, so that the electrical signal of the stud structure 123 can be more stably transmitted to the connector 140. In addition, the clamping force of the connector 140 on the stud structure 123 is also improved.

[0173] When the connecting member 140 is specifically configured, it may include only one of the first part 141, the second part 142, and the third part 143 in the above example. For example, when the connecting member 140 is the first part 141, the thermocouple connector 100 can clamp the reference end 12 with a larger outer diameter, such as the screw head structure 122. When the connecting member 140 is the second part 142, the thermocouple connector 100 can clamp the reference end 12 with a smaller outer diameter, such as the lead structure 121. When the connecting member 140 is the third part 143, the thermocouple connector 100 can clamp the reference end 12 with an outer diameter between the lead structure 121 and the screw head structure 122, such as the stud structure 123.

[0174] Reference Fig.12 As shown, in some other examples, the connector 140 may include a first portion 141 and a second portion 142. The first portion 141 is located at the front end of the detection clip 110 to clamp the reference end 12, such as the screw head structure 122. The second portion 142 is located in the middle of the detection clip 110. For example, the second portion 142 may be located at a first position in the middle of the detection clip 110 to clamp the reference end 12, such as the lead structure 121. The elastic structures of the first portion 141 and the second portion 142 are different, so that the first portion 141 and the second portion 142 are used to abut against different reference ends 12.

[0175] For example, the connector 140 may include a first part 141 and a second part 142 which are sequentially connected in the front-to-back direction, wherein the first part 141 is located at the front end of the second part 142. For example, the third end of the second part 142 may be connected to the second end of the first part 141. In this way, at least two types of reference ends 12, namely the lead structure 121 and the screw head structure 122, may be stably clamped by the connector 140 and the detection clamp 110, thereby improving the applicability of the thermocouple connector 100.

[0176] In this example, one end of the connection line 120 is connected to the fourth end of the second portion 142 .

[0177] It should be noted that one end of the connecting line 120 can be directly connected to the fourth end of the second portion 142. Fig.12As shown, of course, in some examples, the connecting member 140 may also include a fourth portion 144, one end of the fourth portion 144 is connected to the second portion 142, and the other end is connected to the connecting line 120, and at least a portion of the fourth portion 144 is fixed to the detection clamp 110, such as the first clamp body 11a, so that the connecting member 140 is firmly fixed to the first clamp body 11a.

[0178] Exemplarily, the first portion 141 and the second portion 142 of the connecting member 140 are integrally formed, and along the front-to-rear direction of the detection clamp 110 , a portion of the third portion 143 of the connecting member 140 is formed on the first portion 141 , and another portion of the third portion 143 is formed on the second portion 142 .

[0179] For example, the front half of the groove is formed in the rear half of the first part 141, and the rear half of the groove is formed in the front half of the second part 142. In this way, on the basis of ensuring that the first part 141, the second part 142 and the third part 143 are provided on the connecting member 140, the overall extension length of the connecting member 140 can be reduced, thereby saving the manufacturing cost of the connecting member 140. In addition, the size occupied by the connecting member 140 on the detection clip 110 is also saved, thereby providing sufficient setting space for other structural parts or the structure of the detection clip 110 itself. For example, the thickness of the detection clip 110 can be increased to enhance the structural strength of the detection clip 110, and the size of the entire detection clip 110 can be ensured to be within an appropriate range.

[0180] The connector 140 has a first portion 141, a second portion 142, and a third portion 143, which can enrich the applicability of the thermocouple connector 100. For example, the thermocouple connector 100 can clamp and detect three structures with different outer diameters, such as the screw head structure 122, the lead structure 121, and the stud structure 123. In addition, the first portion 141, the second portion 142, and the third portion 143 are integrally formed, which simplifies the structure of the connector 140 and improves the structural strength of the connector 140.

[0181] Fig.13 is a partial structural schematic diagram of another thermocouple connector provided in one embodiment of the present application. Fig.14 yes Fig.13 Schematic diagram of the structure of the middle jacket. Fig.13 and Fig.14 As shown, in some examples, the thermocouple connector 100 may include a jacket 150, the jacket 150 having a sleeve 151 and a handle 152, wherein the sleeve 151 is sleeved on the detection clamp 110, and the head end of the handle 152 is integrally connected to the tail end of the sleeve 151. The thermal conductivity of the jacket 150 is less than the thermal conductivity of the clamping portion 1111. Fig.14As shown, the portion on the right side of the dotted line can be understood as the sleeve portion 151, and the portion on the left side of the dotted line can be understood as the handle portion 152. The position of the dotted line is only an example and can be biased to the left or the right.

[0182] In addition, the provision of the jacket 150 can prevent external electrical signals from interfering with the electrical signals in the connector 140 and affecting the transmission stability of the thermocouple connector 100 for the electrical signals, thereby improving the measurement accuracy of the temperature measurement system 20 for the thermocouple 10 .

[0183] For example, the sleeve 151 may include a first sleeve 151a and a second sleeve 151b, wherein the first sleeve 151a may be sleeved on the outside of the first clamp 11a, and the front end of the first sleeve 151a may be located at the front or middle of the first clamp 11a, and the second sleeve 151b may be sleeved on the outside of the second clamp 11b, and the front end of the second sleeve 151b may be located at the front or middle of the second clamp 11b.

[0184] Among them, the connection position between the first sleeve 151a and the second sleeve 151b can have structural elasticity, so that the connection position provides additional clamping force support for the first clamp body 11a and the second clamp body 11b, thereby improving the clamping stability of the detection clamp 110 on the reference end 12, and further ensuring that the connecting piece can stably contact the reference end 12.

[0185] The head end of the handle 152 of the jacket 150 and the tail end of the sleeve 151 can be integrally connected, so that the manufacturing and assembly process of the jacket 150 can be simplified and the structural strength of the jacket 150 can be improved.

[0186] Reference Fig.13 and Fig.14 As shown, in some examples, the handle 152 of the jacket 150 can be a rigid member, so that the handle 152 can be formed into a hollow structure, that is, an inner cavity 152a is formed in the handle 152, and the inner cavity 152a is connected to the inner cavity 152a of the sleeve 151. A part of the rear part of the detection clip 110 can extend into the inner cavity 152a of the handle 152, and there is a certain distance between the rear end of the handle 152, that is, the detection clip 110 does not need to completely fill the entire length direction of the handle 152, and the detection clip 110 can be opened and closed by pressing the handle 152. In this way, the length of the detection clip 110 can be reduced, thereby reducing the amount of the detection clip 110, and saving the production cost of the detection clip 110.

[0187] In addition, by configuring the handle 152 as a rigid member, additional structural rigidity support can be provided to the detection clip 110 , so that the detection clip 110 does not need to be made too thick to achieve sufficient structural strength.

[0188] Exemplarily, the handle portion 152 may include a clamping handle portion 1521 and a lead portion 1522, wherein the clamping handle portion 1521 may be connected to the tail end of the second sleeve portion 151b, and the inner side of the clamping handle portion 1521 has an inner cavity 152a, so that the rear portion of the second clamp body 11b (the portion after the hinge structure 11c) extends therein, and there is a certain distance between the rear end of the second clamp body 11b and the end of the inner cavity 152a.

[0189] By setting the clamping handle 1521 as a rigid part, when force is applied to the clamping handle 1521, the clamping portion 1111 of the second clamping body 11b can be moved away from the clamping portion 1111 of the first clamping body 11a, so that the clamping portion 1111 opens. Releasing the force on the clamping handle 1521 can make the clamping portion 1111 of the second clamping body 11b move toward the clamping portion 1111 of the first clamping body 11a, so that the clamping portion 1111 is closed or clamped on the surface of the reference end 12.

[0190] In addition, the lead portion 1522 can be connected to the tail end of the first sleeve portion 151a, and the lead portion 1522 can also be set as a rigid part. In this way, it can play a role similar to the clamp handle portion 1521. For example, the rear part of the first clamp body 11a does not need to extend to the tail end of the lead portion 1522, and the first clamp body 11a can be moved by applying force to the lead portion 1522. For details, please refer to the structure and effect of the above-mentioned clamp handle portion 1521, which will not be repeated here.

[0191] In some examples, the handle 152 is further provided with a lead wire through hole 152 b , and the connecting wire 120 can be passed through the lead wire through hole 152 b , thereby protecting the connecting wire 120 .

[0192] For example, the connector 140 is located on the first clamp 11a, and the first clamp 11a is connected to the first connecting wire 120a, then the lead through hole 152b can be set in the lead portion 1522 of the handle 152 for the first connecting wire 120a to pass through. The lead portion 1522 can protect the connecting wire passing through it, preventing the line from being overstressed or bent, thereby affecting the connection stability between the connector 140.

[0193] Fig.15 is a partial structural diagram of another thermocouple connector provided in one embodiment of the present application. Fig.16 yes Fig.15 Schematic diagram of the assembly of the thermocouple connector and the reference end. Fig.15 and Fig.16As shown, different from the above examples, in some examples, the detection clamp 110 may include a first clamp body 11a and a second clamp body 11b that can be opened and closed with each other, the first clamp body 11a has a first clamping surface 111, and the second clamp body 11b has a second clamping surface 112, the first clamping surface 111 and the second clamping surface 112 are used to clamp the reference end 12, that is, in this example, the reference end 12 is clamped by two clamping surfaces.

[0194] In addition, the detection clamp 110 may also include a force storage member 115, which is used to provide a force toward each other for the first clamping surface 111 and the second clamping surface 112 when the first clamping surface 111 and the second clamping surface 112 are opened, so that the first clamping surface 111 and the second clamping surface 112 have a tendency to close.

[0195] For example, when it is necessary to clamp the reference end 12, the first clamping surface 111 and the second clamping surface 112 can be opened by an external force, and the reference end 12 can be extended between the first clamping surface 111 and the second clamping surface 112. Then the external force is released, and the first clamping surface 111 and the second clamping surface 112 can move toward each other under the action of the force storage member 115 to stably clamp the reference end 12.

[0196] At least a portion of the connecting member 140 is located between the first clamping surface 111 and the second clamping surface 112 , and when the first clamping surface 111 and the second clamping surface 112 clamp the reference end 12 , the connecting member 140 contacts the reference end 12 .

[0197] When set, the connecting member 140 located between the first clamping surface 111 and the second clamping surface 112 can be a plate-like member, that is, the bottom surface and the top surface of the connecting member 140 are both flat. When the connecting member 140 is fixed on the first clamping body 11a, the bottom surface of the connecting member 140 contacts the first clamping surface 111. When the first clamping surface 111 and the second clamping surface 112 clamp the reference end 12, the bottom wall of the reference end 12 can contact the top surface of the connecting member 140, thereby transmitting the electrical signal to the connecting member 140.

[0198] It is understandable that the structure of the connecting member 140 between the first clamping surface 111 and the second clamping surface 112 may be consistent with the above example, and will not be described in detail here.

[0199] In some examples, the force storage member 115 may include a first magnetic member and a second magnetic member with opposite magnetic properties, wherein the first magnetic member is disposed on one of the first clamp 11a and the second clamp 11b, and the second magnetic member is disposed on the other of the first clamp 11a and the second clamp 11b. For example, the first magnetic member may be disposed on the first clamping surface 111, and the second magnetic member may be disposed on the second clamping surface 112.

[0200] When setting, one of the first magnetic part and the second magnetic part can be a magnet, and the other can be a magnetic conductive material, or the first magnetic part and the second magnetic part are magnets with opposite magnetic properties. The embodiment of the present application does not limit the structure and setting method of the first magnetic part and the second magnetic part.

[0201] Through the mutual attraction between the first magnetic member and the second magnetic member, the first clamping surface 111 and the second clamping surface 112 can have a force acting toward each other. When the reference end 12 needs to be clamped, the first clamping surface 111 and the second clamping surface 112 can be opened by external force, and the reference end 12 can extend between the first clamping surface 111 and the second clamping surface 112. Then the external force is released, and the first clamping surface 111 and the second clamping surface 112 can move toward each other under the action of the first magnetic member and the second magnetic member to stably clamp the reference end 12.

[0202] In other examples, the force storage member 115 may include a fastening elastic member such as a spring, one end of the fastening elastic member is connected to the first clamping body 11a, and the second end of the fastening elastic member is connected to the second clamping body 11b. When the first clamping surface 111 and the second clamping surface 112 are opened, the fastening elastic member is in a first compression state, and when the first clamping surface 111 and the second clamping surface 112 are in contact, the fastening elastic member is in a second compression state, and the elastic force in the first compression state is greater than the elastic force in the second compression state, so that the fastening elastic member in the first compression state can rebound to the second compression state under the action of elasticity, thereby ensuring that when the first clamping surface 111 and the second clamping surface 112 are opened, the first clamping surface 111 and the second clamping surface 112 have a restoring force toward each other, so that when the reference end 12 is clamped between the first clamping surface 111 and the second clamping surface 112, the first clamping surface 111 and the second clamping surface 112 can rebound to the clamping state.

[0203] For example, the first compression state may be a stretched state of the fastening elastic member, and the second compression state may be a natural state or a compressed state of the fastening elastic member. For another example, the first compression state and the second compression state are both compressed states of the fastening elastic member, and the degree of compression of the first compression state is greater than that of the second compression state. The above two forms of compression states can make the elastic force of the fastening elastic member in the first compression state greater than that in the second compression state, so that the fastening elastic member can automatically rebound from the first compression state to the second compression state, so that when the reference end 12 is clamped between the first clamping surface 111 and the second clamping surface 112, the first clamping surface 111 and the second clamping surface 112 can rebound to the clamping state and clamp the reference end 12. The embodiments of the present application do not specifically limit the forms of the first compression state and the second compression state.

[0204] When the fastening elastic member is specifically set up, a force storage chamber 111a can be provided in the middle part of the first clamp body 11a, and the fastening elastic member is arranged in the force storage chamber 111a. A bending portion 114 is formed at one end of the second clamp body 11b, and the bending portion 114 is bent toward the direction of the first clamp body 11a. The bending portion 114 forms a second clamping surface 112 on a side facing the first clamp body 11a, and a first clamping surface 111 is formed on a side of the first clamp body 11a facing the bending portion 114. The second clamp body 11b passes through the force storage chamber 111a, and a pushing portion 113 is formed at the other end of the second clamp body 11b.

[0205] Exemplarily, the two ends of the second clamp 11b can pass through the bottom and top of the first clamp 11a, and at least part of the two ends of the second clamp 11b is located in the force storage chamber 111a, wherein one end of the second clamp 11b, for example, the top end, is formed with a bending portion 114, and the side of the bending portion 114 facing the top of the first clamp 11a is the second clamping surface 112, and correspondingly, the end of the top of the first clamp 11a facing the bending portion 114 is the first clamping surface 111. The other end of the second clamp 11b, for example, the bottom end, extends out of the bottom of the first clamp 11a and forms a pushing portion 113.

[0206] In addition, one end of the fastening elastic member abuts against the cavity wall of the force storage cavity 111a, and the other end is fixed to the second clamp 11b. For example, the fastening elastic member can be a spring sleeved on the second clamp 11b, one end of the spring is connected to the second clamp 11b, such as connected to the bottom of the second clamp 11b, and the other end abuts against the inner wall of the force storage cavity 111a, such as abutting against the inner top wall of the force storage cavity 111a.

[0207] When it is necessary to measure the reference end 12, the pushing portion 113 can be pushed toward the first clamping body 11a, the first clamping surface 111 and the second clamping surface 112 are opened, and the fastening elastic member is compressed during the rising process of the second clamping body 11b, and then the reference end 12 is extended between the first clamping surface 111 and the second clamping surface 112, and the pushing portion 113 is released, the fastening elastic member rebounds to the initial state, and drives the second clamping body 11b to move downward, so that the second clamping surface 112 moves toward the first clamping surface 111 and abuts against the reference end 12, thereby fixing the reference end 12.

[0208] When the connecting member 140 is specifically configured, a portion thereof may be located between the first clamping surface 111 and the second clamping surface 112 to contact the reference end 12 , and another portion thereof may be located at the periphery of the first clamping body 11 a and connected to the connecting member 140 .

[0209] In some examples, a mounting through hole may be formed in the first clamp body 11a, a portion of the connector 140 is located between the first clamping surface 111 and the second clamping surface 112, and is in contact with and connected to the reference end 12 when the detection clamp 110 clamps the reference end 12, and another portion of the connector 140 is passed through the mounting through hole and connected to the connection line. For example, the connector 140 may extend from the top port of the mounting through hole into the first clamp body 11a, and extend from the bottom port of the mounting through hole to be connected to the connection line.

[0210] By passing a portion of the connecting member 140 through the mounting through hole of the first clamp body 11a, on the one hand, it can protect the connecting member 140, and on the other hand, it can make the connecting member 140 more stably arranged in the first clamp body 11a, thereby improving the assembly stability of the connecting member 140 in the detection clamp 110, so that a portion of the connecting member 140 is more stably arranged between the first clamping surface 111 and the second clamping surface 112, so as to stably contact the reference end 12 when the detection clamp 110 clamps the reference end 12.

[0211] In some examples, the curvature of the bent portion 114 can be greater than 90°, so that a portion of the bent portion 114, such as the free end, can be bent toward the first clamping body 11a, thereby shielding the opening of one side of the first clamping surface 111 and the second clamping surface 112, so as to restrict the reference end 12 within the bent portion 114, that is, to ensure that the reference end 12 is firmly fixed between the first clamping surface 111 and the second clamping surface 112, and will not escape from one side of the first clamping surface 111 and the second clamping surface 112. When setting, the bent portion 114 can have a suitable curvature of 180°, 250° or 300°, which can be adjusted according to actual conditions.

[0212] The detection clamp 110 of the embodiment of the present application, for example, the first clamp body 11a and the second clamp body 11b, can be an insulating member to prevent the electrical signal on the reference end 12 from being transmitted into the detection clamp 110 and causing loss of the electrical signal on the connecting member 140, thereby improving the accuracy of the electrical signal transmitted from the connecting member 140 to the measuring instrument 200. In addition, by setting the detection clamp 110 as an insulating member, it is also prevented that the external electrical signal interferes with the connecting member 140, that is, it plays the role of detecting the internal and external signals of the clamp 110.

[0213] Reference Figure 2 and Figure 3 As shown, in the embodiment of the present application, one end of the connecting wire 120 is connected to the connecting member 140 , and the other end of the connecting wire 120 is connected to the signal connector 130 , which is used to connect to the measuring instrument 200 to transmit the electrical signal of the reference end 1212 to the measuring instrument 200 .

[0214] For example, the measuring instrument 200 has a signal interface 211, and the signal connector 130 can be electrically connected to the signal interface 211 to transmit an electrical signal such as a voltage value to the measuring instrument 200. For example, the signal connector 130 can be directly plugged into the signal interface 211 to achieve an electrical connection between the measuring instrument 200 and the signal connector 130.

[0215] By setting a signal connector at one end of the connecting line and connecting the signal connector to the signal interface on the measuring instrument 200 through plugging and unplugging, the connection structure is simple, which improves the electrical connection efficiency between the measuring instrument 200 and the thermocouple connector 100. In addition, it is convenient to replace the thermocouple connector 100 or the measuring instrument 200 separately.

[0216] Continue to refer to Figure 2 As shown, exemplarily, the measuring instrument 200 may include a shell 210, and a signal interface 211 may be provided on one side of the shell 210, such as the upper part, wherein the signal interface 211 has two, one signal interface 211 is used to electrically connect the first connecting line 120a of the first detection clamp 110a, and the other signal interface 211 is used to electrically connect the second connecting line 120b of the second detection clamp 110b.

[0217] For the convenience of description, the signal connector 130 at one end of the first connection line 120a may be referred to as a first signal connector 130a, and the signal connector 130 at one end of the second connection line 120b may be referred to as a second signal connector 130b.

[0218] Correspondingly, one of the signal interfaces 211 is called the first signal interface 211a, which is connected to the first signal connector 130a to receive the electrical signal of the positive portion 12a of the reference end 12, and the other signal interface 211 is called the second signal interface 211b, which is electrically connected to the second signal connector 130b to receive the electrical signal of the negative portion 12b of the reference end 12.

[0219] Fig.17 Schematic diagram of signal connection of a temperature measurement system provided by an embodiment of the present application. Figure 7 As shown, the measuring instrument 200 may include a voltage measuring module 220, which may be located inside the housing 210, and the voltage measuring module 220 is electrically connected to the signal interface 211, and is used to measure the voltage value of the electrical signal. For example, the voltage measuring module 220 is electrically connected to the first signal interface 211a and the second signal interface 211b, respectively, to form a voltage measurement loop, and measure the electrical signal of the positive electrode portion 12a of the reference terminal 12 and the electrical signal of the negative electrode of the reference terminal 12.

[0220] In some examples, the measuring instrument 200 has at least two groups of signal interfaces 211, and the voltage measurement modules 220 have at least two groups. Different voltage measurement modules 220 have different measurement accuracy, and different groups of signal interfaces 211 are electrically connected to different voltage measurement modules 220. In this way, during the measurement and detection process, the corresponding voltage measurement module 220 can be selected according to the accuracy of the thermocouple 10, so that the measurement accuracy level of the voltage measurement module 220 is higher than or equal to the measurement accuracy level of the thermocouple 10.

[0221] For example, two groups of signal interfaces 211, namely signal interface a and signal interface b, may be provided on the housing 210 of the measuring instrument 200, and each group of signal interfaces 211 has a first signal interface 211a and a second signal interface 211b to connect the first signal connector 130a and the second signal connector 130b. Accordingly, there may be two voltage measurement modules 220, and the measurement accuracy of the two voltage measurement modules 220 is different, that is, the measurement accuracy of one of the voltage measurement modules 220 (i.e., the first voltage measurement module 220) is lower than the measurement accuracy of the other voltage measurement module 220 (i.e., the second voltage measurement module 220). Among them, the signal interface a is electrically connected to the first voltage measurement module 220, and the signal interface b is electrically connected to the second voltage measurement module 220.

[0222] When the accuracy level of the thermocouple 10 to be measured is lower than or equal to the accuracy level of the first voltage measurement module 220, the first voltage measurement module 220 can be selected to measure the voltage value of the reference end 12 of the thermocouple 10. For example, the signal connector 130 can be electrically connected to the signal interface a to transmit the electrical signal to the first voltage measurement module 220.

[0223] When the accuracy level of the thermocouple 10 to be measured is greater than the accuracy level of the first voltage measurement module 220, and less than or equal to the second voltage measurement module 220, the second voltage measurement module 220 can be selected to measure the voltage value of the reference end 12 of the thermocouple 10. For example, the signal connector 130 can be electrically connected to the signal interface b to transmit the electrical signal to the second voltage measurement module 220.

[0224] In some examples, an input module 230 may be provided on the housing 210 , and the input module 230 is used to input relevant calculation parameters of the thermocouple 10 , and the calculation parameters may include a thermocouple coefficient of the thermocouple 10 , etc.

[0225] In some examples, the measuring instrument 200 may also include a processing module 240, which is respectively connected to the voltage measurement module 220 and the input module 230, and processes and calculates the voltage value and the temperature value of the reference end 12 based on the relevant technical parameters of the thermocouple 10 to finally obtain the temperature value of the measured position.

[0226] Continue to refer to Fig.17 As shown, illustratively, the working process of the temperature measurement system 20 in the embodiment of the present application is as follows:

[0227] The first detection clamp 110 a is clamped on the positive electrode portion 12 a of the reference end 12 of the thermocouple 10 , and the second detection clamp 110 b is clamped on the negative electrode portion 12 b of the reference end 12 of the thermocouple 10 .

[0228] According to the accuracy of the thermocouple 10, a suitable voltage measurement module 220 is selected, and the signal connector 130, such as the first signal connector 130a and the second signal connector 130b, is connected to the corresponding first signal interface 211a and the second signal interface 211b respectively.

[0229] Relevant calculation parameters of the thermocouple 10 are input to the processing module 240 through the input module 230 , and the calculation parameters may include a thermocouple coefficient of the thermocouple 10 .

[0230] The measuring end 11 of the thermocouple 10 is located at the position to be measured, and the reference end 12 of the thermocouple 10 is located at the reference environment. The thermocouple 10 generates a thermoelectromotive force according to the relative temperature of the position to be measured and the reference environment, and outputs the thermoelectromotive force through its reference end 12 .

[0231] The voltage measurement module 220 measures the thermoelectromotive force through the connecting wire 120 and the connecting piece 140, and transmits the voltage value to the processing module 240. The temperature measurement module transmits the measured temperature value to the processing module 240. The processing module 240 calculates according to the calculation parameters, temperature value and voltage value obtained above to obtain the measurement value of the thermocouple 10, that is, the temperature of the position to be measured.

[0232] The embodiment of the present application provides a thermocouple connector and a temperature measurement system. The reference end of the thermocouple is clamped by a detection clamp to secure the reference end of the thermocouple on the thermocouple connector, and then the reference end is contacted and connected by a connector arranged in the detection clamp, so that the electrical signal of the reference end is transmitted to the measuring instrument through the connector and the connecting wire to obtain the voltage value of the reference end. Compared with the related art of welding the connecting wire to the reference end, the embodiment of the present application simplifies the connection process between the thermocouple connector and the reference end of the thermocouple, improves the measurement efficiency, and can also quickly remove the thermocouple connector from the reference end, so that the thermocouple connector can measure other types of thermocouples. In addition, the setting of the connecting piece in the detection clamp, on the one hand, realizes the transmission of the electrical signal of the reference end, and on the other hand, in order to accurately transmit the electrical signal to the measuring instrument, only the material of the connecting piece needs to be considered. The material of the detection clamp can be different from that of the connecting piece, thereby making the manufacturing material of the detection clamp more flexible.

[0233] The connecting member and the connecting wire can be structural members with the same Seebeck coefficient. In this way, the contact potential difference between the connecting member and the connecting wire can be reduced, so that the voltage value on the reference end can be accurately transmitted to the measuring instrument through the connecting member and the connecting wire, thereby obtaining a more accurate voltage measurement value.

[0234] By making the connecting piece an elastic structure, when the detection clamp clamps the reference end, the connecting piece elastically abuts against the reference end to improve the contact tightness between the connecting piece and the reference end, so that the electrical signal on the reference end can be transmitted to the connecting piece more stably.

[0235] By setting the connecting piece to include a first part, the reference end of the screw head structure can be stably clamped at the front end of the detection clamp, and the first part is ensured to abut against the rear end of the screw head structure, so that the electrical signal of the screw head structure can be stably transmitted to the first part.

[0236] By configuring the connector to include a second portion, the reference end of the lead structure can be stably clamped at the first middle position of the detection clamp, and the second portion is ensured to abut against the lead structure, so that the electrical signal of the lead structure can be stably transmitted to the second portion.

[0237] By configuring the connecting piece to include a third portion, the reference end of the stud structure can be stably clamped at the second middle position of the detection clamp, and the stud structure is ensured to be embedded in the groove of the third portion to stabilize the stud structure.

It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application.
