Description

Technical Field

[0001] This invention relates to the field of temperature monitoring technology, and more particularly to a temperature sensor. Background Technology

[0002] Circuit breakers are used to control the switching on and off of circuits. The main components of a circuit breaker that perform this function are the moving contact and the stationary contact. Over time, due to contact aging, or prolonged energization, the moving and stationary contacts may overheat. If the temperature of these contacts cannot be monitored, overheating can damage electrical equipment and even cause a fire. Therefore, a passive wireless temperature sensor needs to be installed on the moving contact to obtain its temperature, enabling temperature monitoring and reducing the probability of malfunctions.

[0003] In existing technologies, temperature sensors are fixedly mounted by being clamped onto the fingers of a moving contact via two elastic elements. However, this method suffers from limited installation space and difficulties in installation and disassembly. To address this issue, temperature sensors are fixedly mounted using a structure with movable and fixed grippers. However, the movable grippers exhibit poor stability during movement, resulting in issues such as failure to hold the sensor securely or poor gripping stability. Summary of the Invention

[0004] The purpose of this invention is to provide a temperature sensor that can effectively collect temperature, is easy to install and disassemble, is suitable for installation environments with limited space, has good moving stability of the movable gripper, and has good clamping stability when the temperature sensor is clamped onto the object to be tested.

[0005] To achieve this objective, the present invention adopts the following technical solution: A temperature sensor, comprising: The base has a recessed sliding cavity at its top, which extends through the bottom of the base. The opposite side walls of the sliding cavity are respectively provided with sliding grooves that penetrate the side walls of the sliding cavity. Each sliding groove has a notch on its side wall away from the bottom of the sliding cavity. A fixed gripper, one end of which is connected to the bottom of the base; The movable gripper has one end slidably disposed in the sliding cavity, and two opposite sides of the movable gripper are respectively provided with sliding rods. The sliding rods pass through the notch and slide in the sliding groove along the first direction. The other end of the movable gripper passes through the bottom of the sliding cavity and is opposite to and spaced apart from the fixed gripper. A driving component is disposed on the base. The driving component is used to drive the movable gripper to move along a first direction, so that the movable gripper moves toward the fixed gripper to clamp the object to be tested. A cover plate is disposed on the top of the base, and the cover plate is provided with a plug-in block, which is inserted into the notch; A temperature detection module is disposed on the side of the cover plate away from the base. The temperature detection module is used to detect the temperature transmitted to the base through the fixed clamp and then to the cover plate by the base.

[0006] As an optional technical solution for the aforementioned temperature sensor, the top of the base is provided with a groove, the bottom of the groove is recessed with the sliding cavity, the cover plate is disposed in the groove, and the two opposite ends of the cover plate are respectively provided with the plug-in block.

[0007] As an optional technical solution for the aforementioned temperature sensor, each of the slide bars is provided with a limiting member at the end opposite to the movable gripper. The limiting member is placed outside the slide groove, and the base is clamped between the two limiting members.

[0008] As an optional technical solution for the aforementioned temperature sensor, the temperature sensor further includes a housing, which is placed on the outside of the base. The cover plate and the temperature detection module are placed inside the housing. The housing has clearance openings on opposite sides, which are used to avoid the limiting member.

[0009] As an optional technical solution for the aforementioned temperature sensor, the temperature sensor further includes a reset member disposed within the sliding cavity and connected to the movable gripper. When the driving member moves away from the movable gripper, the reset member drives the movable gripper to move along a second direction, thereby moving the movable gripper away from the fixed gripper to release the object to be detected.

[0010] As an optional technical solution for the aforementioned temperature sensor, the reset member is an elastic reset member, and the top of the base is further recessed with a mounting cavity, which communicates with the sliding cavity. One end of the movable gripper is provided with a mounting seat, and the reset member is disposed in the mounting cavity. One end of the reset member abuts against the cavity wall of the mounting cavity, and the other end of the reset member abuts against the mounting seat. When the driving member drives the movable gripper to move in a first direction, the mounting seat slides into the mounting cavity in the first direction, and the reset member is compressed and stores energy. When the driving member moves away from the movable gripper, the reset member releases energy and drives the mounting seat to slide out of the mounting cavity in a second direction.

[0011] As an optional technical solution for the aforementioned temperature sensor, the mounting base is provided with a mounting groove, a guide rod is provided in the mounting groove, the other end of the reset member is sleeved on the guide rod, and the other end of the reset member abuts against the bottom of the mounting groove.

[0012] As an optional technical solution for the aforementioned temperature sensor, the driving component includes a handle and a screw rod connected in sequence. The base is provided with a screw hole, which communicates with the sliding cavity. The screw rod is screwed into the screw hole. Rotating the handle can cause the screw rod to move along a first direction and push against the movable jaw, or cause the screw rod to move along a second direction and move away from the movable jaw.

[0013] As an optional technical solution for the aforementioned temperature sensor, the temperature sensor further includes a housing, which covers the outside of the base. A stop is fitted on the handle, and the stop is placed between the outer wall of the base and the inner wall of the housing. One end of the handle away from the screw rod passes through the housing and is placed outside the housing. When the screw rod moves in the second direction, the inner wall of the housing can stop the stop, and the stop stops the screw rod to prevent the screw rod from disengaging from the screw hole.

[0014] As an optional technical solution for the aforementioned temperature sensor, the fixed gripper and the base are integrally connected, and the clamping surfaces of both the fixed gripper and the movable gripper are heat-conducting surfaces.

[0015] Beneficial effects: The temperature sensor provided by this invention has a fixed gripper on the base and a movable gripper slidably disposed within a sliding cavity. A driving component drives the movable gripper to move along a first direction, causing it to move towards the fixed gripper to clamp the object to be tested. The driving component is disposed on the base, and the movable and fixed grippers clamp the object to be tested. The installation and removal of the temperature sensor can be achieved by controlling the driving component, making it suitable for installation environments with limited space and facilitating adjustment of the temperature sensor's installation position on the object to be tested. The movable gripper is provided with a sliding rod, which, when installing the movable gripper, can pass through a notch and be placed in a sliding groove. The sliding rod moves along... The sliding mechanism is set in the first direction within the groove. When the driving component drives the movable gripper to move along the first direction, the groove limits and guides the sliding rod, preventing the movable gripper from moving erratically. The plug-in block on the cover plate is inserted into the notch to prevent the movable gripper from dislodging from the groove, ensuring the stability of the movable gripper's movement and the stability of the temperature sensor holding the object to be tested. The temperature of the object to be tested is transmitted to the base through the fixed gripper, and then from the base to the cover plate. The temperature detection module is installed on the cover plate, and the temperature of the object to be tested is indirectly obtained by acquiring the temperature of the cover plate, thus achieving effective acquisition of the temperature of the object to be tested.

[0022] like Figures 1 to 4As shown, this embodiment provides a temperature sensor, which includes a base 1, a fixed gripper 2, a movable gripper 3, a driving component 4, a cover plate 5, and a temperature detection module 6. The top of the base 1 has a recessed sliding cavity 11 that extends through the bottom of the base 1. The opposite side walls of the sliding cavity 11 are respectively provided with sliding grooves 12 penetrating the side walls of the sliding cavity 11. Each sliding groove 12 has a notch 13 on its side wall facing away from the bottom of the sliding cavity 11. One end of the fixed gripper 2 is connected to the bottom of the base 1. One end of the movable gripper 3 is slidably disposed within the sliding cavity 11, and the opposite sides of one end of the movable gripper 3 are respectively provided with sliding rods 31. The sliding rods 31 pass through the notches 13 and slide along a first direction within the sliding grooves 12. The other end of the movable gripper 3 passes through the bottom of the sliding cavity 11 and is spaced apart from the fixed gripper 2. A driving component 4 is mounted on the base 1. The driving component 4 drives the movable gripper 3 to move along a first direction, causing the movable gripper 3 to move towards the fixed gripper 2 to clamp the object to be tested. A cover plate 5 is mounted on the top of the base 1. The cover plate 5 has an insertion block 51, which is inserted into the notch 13. A temperature detection module 6 is located on the side of the cover plate 5 facing away from the base 1. The temperature detection module 6 is used to detect the temperature transmitted through the fixed gripper 2 to the base 1 and then from the base 1 to the cover plate 5.

[0023] The temperature sensor provided in this embodiment has a fixed gripper 2 on the base 1 and a movable gripper 3 slidably disposed in the sliding cavity 11. A driving component 4 is used to drive the movable gripper 3 to move along a first direction, so that the movable gripper 3 moves toward the fixed gripper 2 to clamp the object to be tested. The driving component 4 is disposed on the base 1. The movable gripper 3 and the fixed gripper 2 clamp the object to be tested. The installation and removal of the temperature sensor can be realized by controlling the driving component 4. It is suitable for installation environments with small installation space and facilitates the adjustment of the installation position of the temperature sensor on the object to be tested. The movable gripper 3 is provided with a sliding rod 31. When installing the movable gripper 3, the sliding rod 31 can pass through the notch 13 and be placed in the sliding groove 12. The sliding rod 31 is slidably disposed in the slide groove 12 along the first direction. When the driving component 4 drives the movable gripper 3 to move along the first direction, the slide groove 12 plays a limiting and guiding role for the sliding rod 31, preventing the movable gripper 3 from moving. The plug block 51 on the cover plate 5 is inserted into the notch 13 to prevent the movable gripper 3 from falling out of the slide groove 12, ensuring the stability of the movement of the movable gripper 3, and ensuring the stability of the temperature sensor holding the object to be tested. The temperature of the object to be tested is transmitted to the base 1 through the fixed gripper 2, and then to the cover plate 5 through the base 1. The temperature detection module 6 is installed on the cover plate 5, and the temperature of the object to be tested is indirectly obtained by obtaining the temperature of the cover plate 5, so as to achieve effective acquisition of the temperature of the object to be tested.

[0024] In some embodiments, the top of the base 1 is provided with a groove 14, and the bottom of the groove 14 is provided with a sliding cavity 11. The cover plate 5 is disposed in the groove 14, and the opposite ends of the cover plate 5 are respectively provided with insertion blocks 51. The cover plate 5 is embedded in the groove 14, which improves the compactness of the temperature sensor structure. At the same time as the cover plate 5 is installed, the insertion blocks 51 are inserted into the notch 13. In addition, the small area of ​​the cover plate 5 can concentrate the temperature transmitted to the cover plate 5 and transmit it to the temperature detection module 6, thereby improving the detection accuracy of the temperature sensor.

[0025] The cover plate 5 is connected to the base 1 by means of screwing, riveting, or welding. The cover plate 5, base 1, and fixed clamp 2 are all made of metal with good thermal conductivity. The movable clamp 3 is preferably made of metal, which has high structural strength and can also conduct some heat to the cover plate 5, thereby improving the detection accuracy of the temperature sensor.

[0026] In some embodiments, each slide bar 31 is provided with a limiting member 32 at one end away from the movable gripper 3. The limiting member 32 is placed outside the slide groove 12, and the base 1 is clamped between the two limiting members 32. The limiting members 32 restrict the movement of the movable gripper 3 in the direction in which they are set, and guide the sliding of the movable gripper 3 in the slide cavity 11, so as to ensure that the movable gripper 3 can slide smoothly in the slide cavity 11.

[0027] The limiting member 32 extends toward the bottom side of the base 1 so as to be limited by the side of the base 1, so that the base 1 is clamped between the two limiting members 32.

[0028] Further optional, such as Figure 4 and Figure 5 As shown, the temperature sensor also includes a housing 7, which covers the outside of the base 1. The cover plate 5 and the temperature detection module 6 are placed inside the housing 7, enclosing the temperature detection module 6 and the cover plate 5 within the space enclosed by the housing 7 and the base 1. This protects the temperature detection module 6 from damage, reduces heat loss, and improves the accuracy of the temperature detection by the temperature sensor. The housing 7 has clearance openings 71 on opposite sides. These openings allow for clearance from the limiting member 32. When the driving member 4 does not smoothly drive the movable gripper 3, the position of the movable gripper 3 can be adjusted by manually moving the limiting member 32, improving the flexibility of the temperature sensor.

[0029] In some embodiments, such as Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the temperature sensor also includes a reset component 8, which is disposed within the sliding cavity 11 and connected to the movable gripper 3. When the driving component 4 moves away from the movable gripper 3, the reset component 8 drives the movable gripper 3 to move along a second direction, causing the movable gripper 3 to move away from the fixed gripper 2 to release the object to be tested, thus enabling the temperature sensor to be disassembled. The first direction is the direction in which the movable gripper 3 and the fixed gripper 2 clamp the object to be tested, and the second direction is the direction in which the movable gripper 3 and the fixed gripper 2 release the object to be tested.

[0030] Optionally, the reset member 8 is an elastic reset member, such as a spring. The top of the base 1 is also recessed with a mounting cavity 15, specifically, the mounting cavity 15 is located at the bottom of the groove 14. The mounting cavity 15 communicates with the sliding cavity 11. One end of the movable gripper 3 is provided with a mounting seat 33. The reset member 8 is disposed in the mounting cavity 15, with one end of the reset member 8 abutting against the cavity wall of the mounting cavity 15 and the other end of the reset member 8 abutting against the mounting seat 33. When the driving member 4 drives the movable gripper 3 to move in the first direction, the mounting seat 33 slides into the mounting cavity 15 in the first direction, and the reset member 8 is compressed and stores energy. When the driving member 4 moves away from the movable gripper 3, the driving member 4 no longer applies force to the movable gripper 3, and the reset member 8 releases energy and drives the mounting seat 33 to slide out of the mounting cavity 15 in the second direction, thereby realizing the automatic reset of the movable gripper 3. The mounting seat 33 can slide into or out of the mounting cavity 15, and the mounting cavity 15 limits the mounting seat 33, thereby improving the stability of the sliding of the movable gripper 3.

[0031] The mounting base 33 is provided with a mounting groove 331, and a guide rod 332 is provided in the mounting groove 331. The other end of the reset member 8 is sleeved on the guide rod 332, and the other end of the reset member 8 abuts against the bottom of the mounting groove 331. When the reset member 8 is compressed, the guide rod 332 plays a supporting and guiding role.

[0032] In some other embodiments, the reset member 8 is a bolt or other threaded component. The reset member 8 is disposed opposite to the drive member 4 and is threaded to the base 1. When the drive member 4 drives the movable gripper 3, the reset member 8 moves away from the movable gripper 3, providing clearance for the movable gripper 3 to move in the first direction. When the drive member 4 moves away from the movable gripper 3, the reset member 8 is rotated to press against the movable gripper 3, and the movable gripper 3 moves in the second direction.

[0033] In some embodiments, such as Figure 8 and Figure 9As shown, the driving component 4 includes a handle 41 and a screw rod 42 connected in sequence. The base 1 is provided with a screw hole, which communicates with the sliding cavity 11. The screw rod 42 is screwed into the screw hole. Rotating the handle 41 can move the screw rod 42 in the first direction and push against the movable gripper 3, or move the screw rod 42 in the second direction and move away from the movable gripper 3. This facilitates manual operation to adjust the position of the movable gripper 3 and keeps the movable gripper 3 clamping the object to be tested. The structure is simple.

[0034] Optionally, a stop 9 is fitted onto the handle 41. The stop 9 is positioned between the outer wall of the base 1 and the inner wall of the cover 7. The end of the handle 41 facing away from the threaded rod 42 passes through the cover 7 and is positioned outside the cover 7. When the threaded rod 42 moves in the second direction, the inner wall of the cover 7 can stop the stop 9, which in turn stops the threaded rod 42 to prevent it from disengaging from the threaded hole and thus from detaching from the base 1. After removing the cover 7, the handle 41 can be rotated further to disengage the threaded rod 42 from the threaded hole, thus disassembling the drive component 4. During installation, the stop 9 is fitted onto the handle 41, allowing the threaded rod 42 to be screwed into the threaded hole. This structure, while facilitating the installation and disassembly of the drive component 4, also limits the threaded rod 42, preventing it from disengaging from the threaded hole. Furthermore, the structure is simple and facilitates the assembly of the drive component 4 and the stop 9.

[0035] The stop 9 can be a retaining ring, which is snapped onto the handlebar 41 and does not affect the movement of the handlebar 41 in the first or second direction. When the stop 9 is not stopped by the cover 7, the threaded rod 42 moves in the second direction. When the thread of the threaded rod 42 contacts the stop 9, the stop 9 moves together with the threaded rod 42 in the second direction until the stop 9 is stopped by the inner wall of the cover 7. The stop 9 then stops the threaded rod 42, preventing it from moving further in the second direction. Preferably, the outer diameter of the threaded rod 42 is larger than the outer diameter of the handlebar 41, ensuring sufficient contact between the threaded rod 42 and the stop 9 and effectively driving the stop 9 to move in the second direction.

[0036] In some other embodiments, the driving component includes a screw, which is arranged in a direction perpendicular to the first direction. The screw is screwed to the base 1. The end of the screw is provided with a guide slope. The movable gripper 3 is provided with a wedge, which cooperates with the guide slope. Rotating the screw can make the guide slope cooperate with the wedge, drive the wedge to move in the first direction, and make the movable gripper 3 move in the first direction, so that the movable gripper 3 cooperates with the fixed gripper 2 to clamp the object to be tested.

[0037] In some embodiments, the fixed gripper 2 and the base 1 are integrally connected, resulting in high structural strength. The clamping surfaces of the fixed gripper 2 and the movable gripper 3 are heat-conducting surfaces to better conduct heat to the temperature detection module.

[0038] The fixed gripper 2 includes a fixed clamping plate 21, and a first hook 22 is provided on the side of the fixed clamping plate 21 facing the movable gripper 3. The movable gripper 3 includes a movable clamping plate 34, and sliding rods 31 are respectively provided on opposite sides of one end of the movable clamping plate 34. A second hook 35 is provided on the side of the movable clamping plate 34 facing the fixed gripper 2. The first hook 22 and the second hook 35 are engaged with the object to be tested.

[0039] This temperature sensor can be applied to a circuit breaker with a pentagonal moving contact. A driving component 4 drives a movable gripper 3 to move along a first direction. The movable gripper 3 and the fixed gripper 2 clamp the fingers of the pentagonal moving contact. The temperature of the fingers can be transmitted to the temperature detection module 6 through the fixed gripper 2, the base 1, and the cover plate 5. The pentagonal moving contact has a small installation space; therefore, the temperature sensor provided in this embodiment can be easily installed on the fingers of the pentagonal moving contact, and its installation position on the fingers can be easily adjusted.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
