[0002] Beneath the hood of a car are numerous automotive components, including the engine and cooling system. Each component is connected to pipes through which gases or liquids flow. Some of these pipes are made of metal. During vehicle maintenance, monitoring the temperature of these pipes is a crucial method for determining whether the corresponding automotive components are malfunctioning.

[0003] Currently, commercially available temperature clamps consist of a clamp and a temperature sensor, with the sensor connected to the clamp via multiple layers of connecting media. Therefore, when a temperature clamp is used to measure the temperature of a pipe, the temperature sensor cannot directly contact the pipe due to the multiple layers of connecting media between them. This results in poor thermal conductivity between the sensor and the pipe, longer measurement times, reduced work efficiency in automotive repair, and lower accuracy in pipe temperature detection.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0021] The following detailed description, in conjunction with all the accompanying drawings, describes a temperature detection device 100 provided in this application through specific embodiments.

[0022] Please refer to Figure 1 and Figure 2 One embodiment of this application provides a temperature detection device 100, which includes a handle 10, a thermocouple wire 20, a metal sheet 30, and a circuit assembly 40. Two clamping handles 10 are hinged together. Each clamping handle 10 includes a clamping end 12. The clamping ends 12 of the two clamping handles 10 are arranged opposite to each other. At least one clamping end 12 of the clamping handle 10 is provided with a metal plate 30. The metal plate 30 includes a heat-conducting surface 32. The heat-conducting surface 32 is located on the side of the corresponding metal plate 30 that is close to the other clamping handle 10. A through hole 34 is provided on the metal plate 30. One end of the thermocouple wire 20 passes through the through hole 34 to connect with the corresponding metal plate 30. The other end of the thermocouple wire 20 is electrically connected to the circuit assembly 40. The circuit assembly 40 is provided on the clamping handle 10.

[0023] In this embodiment, since the two clamping handles 10 are hinged together and their clamping ends 12 are positioned opposite each other, when the temperature of the pipe 101 is detected, the pipe 101 is clamped by the clamping ends 12 of the two clamping handles 10, and the heat-conducting surface 32 of the metal sheet 30 is in direct contact with the pipe 101. A through hole 34 is provided for the thermocouple wire 20 to pass through. The thermocouple wire 20 is connected to the metal sheet 30 through the through hole 34, and the through hole 34 has a fixing function on one end of the thermocouple wire 20. Because of the through hole 34, one end of the thermocouple wire 20 can directly contact the pipe 101, and the temperature of the pipe 101 is directly transferred to the thermocouple wire 20. The other end of the thermocouple wire 20 detects the temperature of the pipe 101 and generates a temperature signal, which is then transmitted to the circuit component 40. The circuit component 40 then transmits the temperature signal to the server, thereby improving the efficiency of automotive repair work. In addition, the thermocouple wire 20 has high temperature measurement reliability, and the metal sheet 30 has excellent thermal conductivity, which further improves the thermal conductivity between the pipe 101 and the thermocouple wire 20, saves temperature measurement time, and thus improves the work efficiency of automobile maintenance, while also improving the accuracy of temperature detection of the pipe 101.

[0024] In some specific embodiments, since the pipe 101 is generally a circular pipe, and the thermocouple wire 20 can form a thermally conductive contact with the metal sheet 30 through the through hole 34. Preferably, the metal sheet 30 is arc-shaped, and the arc-shaped metal sheet 30 can fully fit the pipe 101, increasing the contact area between the metal sheet 30 and the pipe 101, thereby improving the thermal conductivity between the metal sheet 30 and the pipe 101, and further improving the thermal conductivity between the pipe 101 and the thermocouple wire 20.

[0025] In some specific embodiments, the number of metal sheets 30 can be one or two, and each metal sheet 30 can be provided with one or more through holes 34. When there is one metal sheet 30, it is located at the clamping end 12 of one of the clamping handles 10, and one end of the thermocouple wire 20 is connected to the metal sheet 30. When there are two metal sheets 30, they are respectively located at the clamping ends 12 of two clamping handles 10, and the number of thermocouple wires 20 can be one or more, with one end of each thermocouple wire 20 connected to one or two metal sheets 30. The thermocouple wire 20 can be a K-type thermocouple wire 20 or a T-type thermocouple wire 20.

[0026] In some embodiments, the circuit assembly 40 includes a PCB board 42, a Bluetooth module 44 and a power module 46, and each handle 10 also includes a gripping end 14, with the gripping ends 14 of the two handles 10 arranged opposite to each other. PCB board 42 is located on the holding end 14, and Bluetooth module 44 and power module 46 are located on PCB board 42. The other end of thermocouple wire 20 is electrically connected to PCB board 42.

[0027] In this embodiment, the Bluetooth module 44 transmits temperature signals to the server based on the Bluetooth protocol, and the power module 46 provides power. The PCB board 42 is located on the gripping end 14, which makes reasonable use of the space of the handle 10 and avoids interference with components such as the metal sheet 30.

[0028] In some specific embodiments, PCB board 42 is short for printed circuit board. The Bluetooth module 44, power module 46, and PCB board 42 are electrically connected. The power module 46 can be a button battery, a rechargeable battery, etc.

[0029] In some specific embodiments, the circuit assembly 40 also includes a reader (not shown in the figure), which is mounted on the PCB board 42 and electrically connected to the other end of the thermocouple wire 20 through the PCB board 42. By setting the reader, the temperature detected by the thermocouple wire 20 can be obtained in real time.

[0030] Please refer to the above as well. Figure 3 and Figure 4 In some embodiments, the temperature detection device 100 further includes a mounting base 70, with one end of each clamp 10 hinged to the mounting base 70, and at least one mounting base 70 having a metal sheet 30.

[0031] In this embodiment, since each clamp 10 is hinged to a mounting base 70 at one end, the metal sheet 30 can swing relative to the corresponding clamp 10 by a certain distance, so that the metal sheet 30 can automatically adapt to the arc surface of the pipe 101, thereby improving the fit between the metal sheet 30 and the pipe 101, increasing the contact area between the metal sheet 30 and the pipe 101, and improving the heat conduction efficiency between the pipe 101, the metal sheet 30 and one end of the thermocouple wire 20.

[0032] In some specific embodiments, the temperature detection device 100 further includes a first connecting shaft 80. Each mounting base 70 includes an arc-shaped block 72 and a connecting block 74. One side of the arc-shaped block 72 forms an arc-shaped surface 722, and the metal sheet 30 is attached to the arc-shaped surface 722 of the corresponding arc-shaped block 72. By setting the arc-shaped surface 722, the metal sheet 30 is made arc-shaped. The connecting block 74 is connected to the opposite side of the arc-shaped block 72, and the connecting block 74 and the arc-shaped block 72 are integrally formed. The connecting block 74 is provided with a first connecting hole 742, and one end of the clamp 10 is provided with a mounting groove 16. The two opposite side walls of the mounting groove 16 are respectively provided with second connecting holes 162. Each connecting block 74 is inserted into the mounting groove 16 of the corresponding clamp 10, and the first connecting shaft 80 passes through the first connecting hole 742 and the corresponding second connecting hole 162 of the corresponding connecting block 74, so that each connecting block 74 and the corresponding clamp 10 are hingedly connected. This configuration enhances the connection strength between the connecting block 74 and the corresponding clamp 10, and allows the connecting block 74, the arc-shaped block 72, and the metal plate 30 to rotate relative to the corresponding clamp 10. The mounting groove 16 of each clamp 10 limits the movement of the corresponding connecting block 74, ensuring that the connecting block 74 rotates relative to the clamp 10 within a certain range and around the first connecting shaft 80. This not only ensures that the metal plate 30 automatically adapts to the arc-shaped surface of the pipe 101, but also prevents displacement of the metal plate 30 after clamping the pipe 101.

[0033] In some embodiments, each mounting base 70 has a clearance groove 76 at the end near the holding end 14; The circuit assembly 40 is located at the other end of the clamp 10, and the thermocouple wire 20 is inserted into the recessed groove 76.

[0034] In this embodiment, the other end of the thermocouple wire 20 can smoothly pass through the recessed groove 76 and extend to the back of the metal sheet 30. This arrangement reduces the wiring length of the thermocouple wire 20 and simplifies its structural layout.

[0035] In some specific embodiments, the clearance groove 76 is formed at one end of the arc-shaped block 72 near the gripping end 14 of the corresponding handle 10. The clearance groove 76 is square, which facilitates the processing and manufacturing of the arc-shaped block 72.

[0036] In some embodiments, the end of the metal sheet 30 near the gripping end 14 of the corresponding handle 10 is also formed as a drive piece 38, which is located at the clearance groove 76.

[0037] In this embodiment, the user can pull out the metal piece 30 through the drive piece 38, which is convenient to operate. The drive piece 38 is located in the relief groove 76, which makes it easier for the user to take out the metal piece 30 through the drive piece 38, and it will not interfere with other components.

[0038] In some embodiments, the temperature detection device 100 further includes an elastic element (not shown) disposed between the two clamps 10 to bring one end of the two clamps 10 closer to each other.

[0039] In this embodiment, an elastic element is provided to bring one end of the two clamps 10 close to each other. When the heat-conducting surfaces 32 of the two metal sheets 30 come into contact with the pipe 101, they can be clamped and fixed onto the pipe 101 under the action of the elastic element.

[0040] In some specific embodiments, the elastic element is a torsion spring, with one end of the torsion spring mounted on a clamp 10 and the other end of the torsion spring mounted on another clamp 10.

[0041] In some specific embodiments, the temperature detection device 100 further includes a second connecting shaft 90. Each clamp 10 has a third connecting hole 18 in its middle portion. The second connecting shaft 90 passes through the third connecting holes 18 of the two clamps 10, so that the middle portions of the two clamps 10 are hinged together. Each clamp 10 has a metal plate 30 and a mounting base 70 at its head, and a circuit assembly 40 is provided at the tail of one of the clamps 10.

[0042] In some specific embodiments, the temperature detection device 100 further includes support blocks 92, with two side-by-side support blocks 92 on each clamp 10, forming a clamping channel 922 between the two support blocks 92, and each thermocouple wire 20 is clamped in the corresponding clamping channel 922.

[0043] In this embodiment, by providing two support blocks 92 on each clamp 10, the clamping channel 922 formed by the two support blocks 92 can provide support and fixation for the corresponding thermocouple wire 20, thus preventing the thermocouple wire 20 from becoming loose or falling off.

[0044] In some specific embodiments, the support block 92 and the corresponding clamping handle 10 are integrally formed, with the support block 92 located at one end near the clamping handle 10.

[0045] In some embodiments, each mounting base 70 has a locking hole 78, and the two ends of the metal sheet 30 form locking portions 35, which are inserted into the corresponding locking holes 78 so that the metal sheet 30 and the corresponding mounting base 70 are snapped together.

[0046] In this embodiment, the locking part 35 of the metal sheet 30 can be locked into the corresponding locking hole 78. With this setting, the metal sheet 30 and the mounting base 70 can be detachably connected, making disassembly and assembly convenient.

[0047] In some specific embodiments, each mounting base 70 has four locking holes 78 on its arc-shaped block 72. The four locking holes 78 pass through the arc-shaped surface 722 and are located at opposite ends of the arc-shaped surface 722. That is, two locking holes 78 are also provided at opposite ends of the arc-shaped surface 722. Correspondingly, there are also four locking parts 35, with two locking parts 35 provided at opposite ends of each metal piece 30.

[0048] Please refer to the above as well. Figures 5 to 7 In some embodiments, one end of the thermocouple wire 20 forms a connector that passes through the through hole 34 and extends to the heat-conducting surface 32.

[0049] In this embodiment, by forming a connector at one end of the thermocouple wire 20, when the temperature of the pipe 101 is detected, the connector directly contacts the pipe 101, allowing a large-area point contact to be formed between the thermocouple wire 20 and the pipe 101, thereby improving the thermal conductivity between the pipe 101 and the thermocouple wire 20. Furthermore, when the diameter of the connector is larger than or comparable to the diameter of the through hole 34, it also prevents one end of the thermocouple wire 20 from detaching from the through hole 34.

[0050] In some specific embodiments, a connector is formed by melting one end of the thermocouple wire 20. The connector includes a positive connector 222 and a negative connector 242. The thermocouple wire 20 includes a positive cable 22 and a negative cable 24, one end of the positive cable 22 can form the positive connector 222, and one end of the negative cable 24 can form the negative connector 242.

[0051] In some embodiments, one end of the thermocouple wire 20 and the metal sheet 30 are connected by laser welding.

[0052] like Figure 5 As shown, in this embodiment, since one end of the thermocouple wire 20 is connected to the metal sheet 30 by laser welding, the connection strength between the thermocouple wire 20 and the metal sheet 30 can be further improved, which has a fixing effect on the connector. When the temperature of the pipe 101 is detected, it is ensured that the connector and the pipe 101 are in close contact. This further improves the heat conduction efficiency between the pipe 101 and the thermocouple wire 20.

[0053] In some specific embodiments, one end of the positive electrode cable 22 is connected to the metal sheet 30 by laser welding, and one end of the negative electrode cable 24 is connected to the metal sheet 30 by laser welding.

[0054] like Figure 6 As shown, in some embodiments, the temperature detection device 100 further includes a first solder paste solidification block 50, and the connection between the thermocouple wire 20 and the corresponding metal sheet 30 is also connected through the first solder paste solidification block 50. The metal sheet 30 also includes a connecting surface 36, which and the heat-conducting surface 32 are located on opposite sides of the metal sheet 30, and the first solder paste solidification block 50 is located on the connecting surface 36.

[0055] In this embodiment, by providing a first solder paste solidification block 50, the connection strength between one end of the thermocouple wire 20 and the metal sheet 30 can be improved, preventing the thermocouple wire 20 from detaching from the metal sheet 30. Furthermore, since the first solder paste solidification block 50 is located on the connection surface 36, it will not affect the contact between the connector and the pipe 101.

[0056] In some specific embodiments, the front side of the metal sheet 30 is a heat-conducting surface 32, the back side of the metal sheet 30 is a connecting surface 36, and the back side of the metal sheet 30 is located near the clamping end 12 of the clamp handle 10.

[0057] In some specific embodiments, the connection between the positive electrode cable 22 and a metal sheet 30 is connected by a first solder paste solidification block 50, and the connection between the negative electrode cable 24 and another metal sheet 30 is connected by another first solder paste solidification block 50.

[0058] like Figure 7 As shown, in some embodiments, the temperature detection device 100 further includes a second solder paste solidification block 60, and the metal sheet 30 has at least two through holes 34. The metal sheet 30 also includes a connecting surface 36, and the connecting surface 36 and the heat-conducting surface 32 are located on opposite sides of the metal sheet 30; One end of the thermocouple wire 20 passes through each of the through holes 34 of a metal sheet 30 and extends to the connection surface 36. The connection between the thermocouple wire 20 and each through hole 34 is also connected by a second solder paste solidification block 60, which is located on the connection surface 36.

[0059] In this embodiment, by providing at least two through holes 34 on each metal sheet 30, one end of the thermocouple wire 20 can sequentially pass through the through holes 34 and extend to the connecting surface 36. When detecting the temperature of the pipe 101, a large-area line contact can be formed between one end of the thermocouple wire 20 and the pipe 101, thereby improving the thermal conductivity between the pipe 101 and the thermocouple wire 20. By providing a second solder paste solidification block 60, the connection strength between one end of the thermocouple wire 20 and the metal sheet 30 can be improved, preventing the thermocouple wire 20 from detaching from the metal sheet 30. Furthermore, since the second solder paste solidification block 60 is located on the connecting surface 36, it will not affect the contact between the thermocouple wire 20 and the pipe 101.

[0060] In some specific embodiments, one end of the positive electrode cable 22 passes through each of the through holes 34 of a metal sheet 30 in sequence and extends to the connection surface 36. The connection between the positive electrode cable 22 and each through hole 34 is also connected by a second solder paste solidification block 60. One end of the negative electrode cable 24 passes through each of the through holes 34 of a metal sheet 30 in sequence and extends to the connection surface 36. The connection between the negative electrode cable 24 and each through hole 34 is also connected by another second solder paste solidification block 60.

[0061] In some embodiments, the number of thermocouple wires 20 is one, and one end of the positive wire 22 and one end of the negative wire 24 are connected to the corresponding metal sheet 30 through at least one through hole 34 on the metal sheet 30.

[0062] In this embodiment, by setting it up in this way, one end of the positive cable 22 and one end of the negative cable 24 can detect the temperature of the pipe 101 at the same metal plate 30.

[0063] In some specific embodiments, when the metal sheet 30 has only one through hole 34, the positive electrode connector 222 and the negative electrode connector 242 can both pass through the same through hole 34. When the metal sheet 30 has two through holes 34, the positive electrode connector 222 passes through one of the through holes 34 and extends to the heat-conducting surface 32, and the negative electrode connector 242 passes through the other through hole 34 and extends to the heat-conducting surface 32. When the metal sheet 30 has two or more through holes 34, for example, when the metal sheet 30 has four through holes 34, the positive electrode connector 222 passes through two of the through holes 34 in sequence and extends to the connection surface 36, and the negative electrode connector 242 passes through the remaining two through holes 34 in sequence and extends to the connection surface 36. The number of metal sheets 30 can be one or two. When the number of metal sheets 30 is one, all of the above-mentioned through holes 34 are provided on the metal sheet 30. When there are two metal plates 30, the through hole 34 is provided on one of the metal plates 30, and the other metal plate 30 may not have a through hole 34. The other end of the positive cable 22 and the other end of the negative cable 24 are electrically connected to the PCB board 42.

[0064] Since the temperature may vary at different points in the pipe 101, in some embodiments, there is only one thermocouple wire 20. One end of the positive wire 22 is connected to the corresponding metal plate 30 through a through hole 34 on a metal plate 30, and one end of the negative wire 24 is connected to the corresponding metal plate 30 through a through hole 34 on another metal plate 30. The other ends of the positive wire 22 and the negative wire 24 are electrically connected to the circuit assembly 40.

[0065] In this embodiment, by setting it up in this way, the temperature of the pipe 101 can be detected at the two metal plates 30, thereby forming two temperature detection points and displaying a more uniform temperature on the reading instrument. This reduces the impact of temperature differences at various points in the pipe 101 and further improves the accuracy of temperature detection of the pipe 101.

[0066] In some specific embodiments, there are two metal plates 30, each with one or more through holes 34. One end of the positive cable 22 can form a positive connector 222, and one end of the negative cable 24 can form a negative connector 242. The connection method between the positive connector 222, the negative connector 242, and the corresponding metal plates 30 will not be described in detail here.

[0067] In some embodiments, the number of thermocouple wires 20 is at least two, each positive wire 22 is connected to a corresponding metal plate 30 through a through hole 34 on a metal plate 30, and each negative wire 24 is connected to a corresponding metal plate 30 through a through hole 34 on another metal plate 30.

[0068] In this embodiment, by setting multiple thermocouple wires 20, the temperature at multiple points on the pipe 101 can be collected, and the average temperature can be obtained based on the temperature detected at multiple points, thereby further improving the accuracy of temperature detection on the pipe 101.

[0069] In some specific embodiments, there may be two thermocouple wires 20 and two metal plates 30. Each metal plate 30 has one or more through holes 34. The positive wires 22 of all thermocouple wires 20 are connected to the metal plate 30 through one or more through holes 34, and the negative wires 24 of all thermocouple wires 20 are connected to the other metal plate 30 through one or more through holes 34.

[0070] It is understandable that the number of thermocouple wires 20 can also be three, four, etc., that is, each metal plate 30 should be connected to at least one positive wire 22 and one negative wire 24 of thermocouple wire 20.

[0071] In some embodiments, the number of thermocouple wires 20 is at least two. One end of the positive electrode cable 22 and one end of the negative electrode cable 24 of at least one thermocouple wire 20 are connected to the corresponding metal plate 30 through at least one through hole 34 on a metal plate 30. One end of the positive electrode cable 22 and one end of the negative electrode cable 24 of at least one thermocouple wire 20 are connected to the corresponding metal plate 30 through at least one through hole 34 on another metal plate 30. The other end of each positive electrode cable 22 and the other end of each negative electrode cable 24 are electrically connected to the circuit assembly 40.

[0072] In this embodiment, by setting multiple thermocouple wires 20, the temperature at multiple points on the pipe 101 can be collected, and the average temperature can be obtained based on the temperature detected at multiple points, thereby further improving the accuracy of temperature detection on the pipe 101.

[0073] In some specific embodiments, the number of thermocouple wires 20 can be two, and the number of metal plates 30 can be two pieces. Each metal plate 30 can have one or more through holes 34. The positive cable 22 and negative cable 24 of one thermocouple wire 20 are connected to the metal plate 30 through one or more through holes 34, and the positive cable 22 and negative cable 24 of the other thermocouple wire 20 are connected to the other metal plate 30 through one or more through holes 34. It is understood that the number of thermocouple wires 20 can also be three, four, etc., that is, at least one thermocouple wire 20's positive cable 22 and negative cable 24 needs to be connected on each metal plate 30.

[0074] In some embodiments, when the positive cable 22 and the negative cable 24 of the same thermocouple wire 20 are connected to the same metal plate 30, the positive cable 22 and the negative cable 24 of the thermocouple wire 20 can share a through hole 34. This arrangement reduces the number of through holes 34. When there is only one thermocouple wire 20, the positive cable 22 and the negative cable 24 can be connected to the same metal plate 30 or to separate metal plates 30. When the positive cable 22 and the negative cable 24 are connected to the same metal plate 30, the positive cable 22 and the negative cable 24 can share a through hole 34 or not. When there are multiple thermocouple wires 20, the positive cables 22 and the negative cables 24 do not share a through hole 34. This arrangement facilitates the collection of temperatures at multiple points in the pipe 101. Only when the positive cable 22 and negative cable 24 of the same thermocouple wire 20 are connected to the same metal plate 30 can the positive cable 22 and negative cable 24 of the thermocouple wire 20 share a common through hole 34. It is understood that the positive cable 22 and negative cable 24 of the same thermocouple wire 20 can also be connected to different metal plates 30. When connected to the same metal plate 30, the positive cable 22 and negative cable 24 of the thermocouple wire 20 can also be connected to the metal plate 30 through a through hole 34 respectively.

[0075] In some embodiments, the positive electrode cable 22 is made of a first material, and the negative electrode cable 24 is made of a second material. In each thermocouple wire 20, when the positive electrode wire 22, the negative electrode wire 24 and the same metal sheet 30 are connected, the metal sheet 30 is made of a third material.

[0076] In this embodiment, the first material, the second material, and the third material are different materials. Because the first and second materials are different, the positive cable 22 and the negative cable 24 can detect the temperature of the pipe 101. The third material is selected to form the metal sheet 30 according to the user's functional requirements. For example, since the metal sheet 30 also has thermally conductive contact with one end of the positive cable 22 and one end of the negative cable 24, and also with the pipe 101, when the third material is high-conductivity copper, the high thermal conductivity of copper further improves the thermal conductivity between one end of the positive cable 22, one end of the negative cable 24, and the pipe 101.

[0077] In some specific embodiments, when the thermocouple wire 20 is a K-type thermocouple wire 20, the first material is a nickel-chromium alloy, the second material is a nickel-silicon alloy, and the third material is high-conductivity copper. It is understood that, depending on the user's needs and the type of thermocouple wire 20, the first, second, and third materials can also be other materials. Furthermore, according to the user's requirements, protective and insulating layers can be provided on the surfaces of the positive cable 22 and negative cable 24 other than those in contact with the pipe 101 to protect the positive cable 22 and negative cable 24.

[0078] In some embodiments, when the positive electrode cable 22 is connected to a metal plate 30 and the negative electrode cable 24 is connected to another metal plate 30 in each thermocouple wire 20, the metal plate 30 connected to the positive electrode cable 22 is made of one of a first material and a third material, and the metal plate 30 connected to the negative electrode cable 24 is made of one of a second material and a third material.

[0079] In this embodiment, when one end of the positive electrode cable 22 and one end of the negative electrode cable 24 in a thermocouple wire 20 are respectively connected to two metal plates 30, the materials of the corresponding metal plates 30 and the positive electrode cable 22 can be the same or different. When the material of the metal plate 30 is the same as that of the positive electrode cable 22, interference with the temperature detection of the positive electrode cable 22 can be avoided. When the material of the metal plate 30 is different from that of the positive electrode cable 22, other user needs can be met. For example, when the material of the positive electrode cable 22 is nickel-chromium alloy and the metal plate 30 is made of high-conductivity copper, the thermal conductivity can be improved. Similarly, when the material of the metal plate 30 is the same as that of the negative electrode cable 24, interference with the temperature detection of the negative electrode cable 24 can be avoided. When the material of the metal plate 30 is different from that of the negative electrode cable 24, other user needs can be met. For example, when the material of the negative electrode cable 24 is nickel-silicon alloy and the metal plate 30 is made of high-conductivity copper, the thermal conductivity can be improved.

[0080] In some specific embodiments, the positive electrode cable 22 may also be made of other materials, such as an insulation layer and a protective layer. Similarly, the negative electrode cable 24 may also be made of other materials, including an insulation layer and a protective layer. Specifically, the positive electrode cable 22 includes a positive electrode core and an insulation layer, with the insulation layer covering the surface of the positive electrode core, which is made of a nickel-chromium alloy. It is understood that in some specific embodiments, the insulation layer may be omitted. Similarly, the negative electrode cable 24 may include a negative electrode core and an insulation layer, with the negative electrode core made of a nickel-silicon alloy. It is understood that in some specific embodiments, the insulation layer may be omitted.
