Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, and specifically to an integrated temperature sensor. Background Technology

[0002] Integrated sensors are sensors fabricated using silicon semiconductor integration technology, hence they are also called silicon sensors or monolithic integrated sensors. Analog integrated sensors emerged in the 1980s; they are dedicated ICs that integrate sensors onto a single chip, enabling both measurement and analog signal output.

[0003] During prolonged use, integrated temperature sensors are prone to dust accumulation at their open terminals. Once dust enters the connection surface of the terminals, it can easily lead to poor circuit contact and affect the normal operation of the sensor.

[0004] In summary, existing integrated temperature sensors suffer from the problem of dust accumulating at the wiring terminals, leading to poor circuit contact. Utility Model Content

[0005] The purpose of this invention is to provide an integrated temperature sensor to solve the technical problem that most existing integrated temperature sensors have dust accumulation at the wiring terminals, causing poor circuit contact.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] An integrated temperature sensor includes an integrated terminal and a wiring terminal disposed on the integrated terminal.

[0008] One end of the terminal is provided with a threaded tube, and the threaded tube is located on the outside of the terminal. A dustproof component is provided on the threaded tube.

[0009] The dustproof assembly includes a protective sleeve that is threaded to a threaded pipe, movable grooves symmetrically opened at both ends of the bottom of the protective sleeve, a dustproof bag disposed inside the protective sleeve, several sets of guide frames symmetrically disposed at both ends of the dustproof bag, a binding strap disposed around both ends of the dustproof bag, and the binding strap can tighten both ends of the dustproof bag, the binding strap passing through the inside of the guide frame in sequence, a cable tie disposed at one end of the binding strap passing through the movable groove, a limiting seat disposed at both ends of the bottom of the protective sleeve, and the inside of the limiting seat can hold the cable tie, a lifting handle movably disposed at the bottom of the limiting seat, a limiting plate disposed at the top of the lifting handle to engage with the cable tie, and a reset spring disposed on the outside of the lifting handle.

[0010] As a further embodiment of this utility model: the two sides of the limiting plate are in contact with the inner wall of the limiting seat.

[0011] As a further embodiment of this utility model: the two ends of the reset spring are respectively connected to the bottom of the limiting seat and the bottom wall of the lifting handle.

[0012] As a further embodiment of this utility model: a sealing cover is movably provided on the top of the integrated terminal, and the sealing cover is connected to the wiring terminal by a traction rope.

[0013] As a further embodiment of this utility model: the input end of the integrated terminal is provided with a connecting shaft, and the input end of the connecting shaft is provided with a temperature probe.

[0014] As a further embodiment of this utility model: a sealing seat is slidably provided at the bottom end of the connecting shaft, and a positioning nut is threadedly connected to the bottom end of the connecting shaft, with the positioning nut located above the sealing seat.

[0015] As a further embodiment of this utility model, a locking groove is provided at one end of the protective sleeve.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figure 1-3 As shown, an integrated temperature sensor includes an integrated terminal 1 and a terminal 2 disposed on the integrated terminal 1. A circuit board is disposed inside the integrated terminal 1, and a sensor chip is disposed on the circuit board for receiving and transmitting signals. One end of the terminal 2 is provided with a threaded tube 3, and the threaded tube 3 is located outside the terminal 2. A dustproof component is disposed on the threaded tube 3. The terminal 2 is used to pass through a cable so that the cable can be connected to the circuit board.

[0029] The dustproof assembly includes a protective sleeve 10 threadedly connected to a threaded tube 3, movable grooves 14 symmetrically formed at both ends of the bottom of the protective sleeve 10, a dustproof bag 15 disposed inside the protective sleeve 10, several sets of guide frames 17 symmetrically arranged at both ends of the dustproof bag 15, and binding straps 18 surrounding both ends of the dustproof bag 15, the binding straps 18 being able to tighten both ends of the dustproof bag 15. The binding straps 18 pass through the interior of the guide frames 17 in sequence, one end of the binding strap 18 is connected to a set of guide frames 17 at the bottom of the dustproof bag 15, and the other end passes through the guide frames 17 at the same end in sequence and then exits from the guide frames 17 at the bottom of the dustproof bag 15. The strap 18 extends into the frame 17, thus ensuring that the binding strap 18 can smoothly tighten both ends of the dust bag 15. A cable tie 19 is provided at one end of the binding strap 18, passing through the movable groove 14. Limiting seats 20 are provided at both ends of the bottom of the protective sleeve 10, and the cable tie 19 can be placed inside the limiting seats 20. A lifting handle 21 is movably provided at the bottom of the limiting seats 20. A limiting plate 22 is provided at the top of the lifting handle 21 to engage with the cable tie 19. The two sides of the limiting plate 22 are in contact with the inner wall of the limiting seat 20. A return spring 23 is provided on the outside of the lifting handle 21, and its two ends are respectively connected to the limiting seat 20. The bottom of the protective sleeve 10 is connected to the bottom wall of the lifting handle 21. The binding strap 18 supports both ends of the dust bag 15, ensuring that both ends of the dust bag 15 are initially open, thus allowing the cable to pass through smoothly. In use, first, the protective sleeve 10 is installed onto the threaded tube 3, so that one end of the dust bag 15 is fitted onto the port of the terminal 2. Then, the cable tie 19 is pulled outwards, causing the corresponding binding strap 18 to retract, thereby fixing one end of the dust bag 15 to the terminal 2. Then, the cable is passed from the other end of the dust bag 15 into the terminal 2, achieving connection with the circuit board. Next, pull another set of cable ties 19 outwards. The limiting plate 22 locks the cable ties 19 in place, allowing them to move only in one direction. This causes the other end of the dust bag 15 to contract, effectively bundling the cable and sealing the cable to the terminal 2, providing good dust protection. When disassembly is needed, the operator pulls the lifting handle 21, causing the return spring 23 to deform and stretch. The limiting plate 22 releases the locking mechanism on the cable ties 19, allowing the operator to slowly retract the cable ties 19, opening both ends of the dust bag 15 for easy cable removal.

[0030] In this embodiment, specifically, a sealing cover 4 is movably provided on the top of the integrated terminal 1, and the sealing cover 4 is connected to the terminal 2 via a traction rope 5. This connection method not only ensures the stability of the sealing cover 4, but also facilitates its opening and closing.

[0031] In this embodiment, specifically, the input end of the integrated end 1 is provided with a connecting shaft 6, the input end of the connecting shaft 6 is provided with a temperature probe 7, the bottom end of the connecting shaft 6 is slidably provided with a sealing seat 8, and the bottom end of the connecting shaft 6 is threadedly connected with a positioning nut 9, and the positioning nut 9 is located above the sealing seat 8. The temperature probe 7, as the front end component of the sensor, directly contacts the object being measured and is used to collect temperature signals. When the device is in use, a hole is first made on the relevant container, and then the temperature probe 7 is inserted. At this time, the sealing seat 8 is inserted into the hole to form a seal. Rotating the positioning nut 9 causes the positioning nut 9 to press down on the sealing seat 8, thereby ensuring that the sealing seat 8 can form a good seal on the hole.

[0032] In this embodiment, specifically, a locking groove 11 is provided at one end of the protective sleeve 10, and a dust cover 12 is rotatably provided at the top of one end of the protective sleeve 10. An annular protrusion 13 matching the locking groove 11 is provided on one side of the dust cover 12. The locking groove 11 and the annular protrusion 13 cooperate with each other to make the connection between the dust cover 12 and the protective sleeve 10 tighter, enhance the sealing of the inside of the protective sleeve 10, further prevent dust from entering the inside of the protective sleeve 10, and improve the dustproof performance of the sensor.

[0033] In this embodiment, specifically, a magnetic strip 16 is arranged around the inner wall of the end of the dust bag 15 near the terminal 2, and the magnetic strip 16 is magnetically fixed to the terminal 2. The magnetic fixing method not only allows one end of the dust bag 15 to quickly form a magnetic fixation with one end of the terminal 2 when the protective sleeve 10 is installed on the threaded tube 3, thus facilitating subsequent tightening and fixing, but also ensures a tight fit between the dust bag 15 and the terminal 2, preventing dust from entering from gaps and improving the dustproof effect and reliability of the sensor.

[0034] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
