[0001] This utility model relates to the field of NTC temperature sensor technology, specifically to a precise mounting structure for an NTC pin header temperature sensor. Background Technology

[0002] NTC temperature sensors typically consist of two or three metal oxides mixed in a popular clay and sintered in a high-temperature furnace to form a dense sintered ceramic. The oxygen-bonded metals often provide free electrons. With the development of electronic technology, electronic thermometers will evolve towards higher precision, higher reliability, faster response, and miniaturization. To meet people's needs for electronic thermometers, this requires thermistor chips to be highly precise, highly reliable, and have a fast response.

A lead wire tightening strap effectively secures the leads, preventing poor contact caused by frequent shaking of the installed equipment or instruments. A merged lead head allows for faster information transmission to the NTC temperature sensor chip. However, the NTC temperature sensor is typically installed using bolts, which requires careful handling, making installation inconvenient and potentially damaging the sensor during installation or removal.

[0005] A precise mounting structure for NTC pin header temperature sensors is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a precise mounting structure for an NTC pin-mount temperature sensor. This addresses the issues raised in the background art, which currently employs a second encapsulating resin to improve the insulation and accuracy of the NTC temperature sensor, a lead wire tightening band to effectively secure the lead wires and prevent poor contact caused by frequent shaking of the installed equipment or instrument, and a merged lead head to facilitate faster information transmission to the NTC temperature sensor chip. However, the NTC temperature sensor is typically installed and disassembled using bolts, which requires careful installation and can be inconvenient, potentially damaging the sensor during installation or disassembly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a precise mounting structure for an NTC pin header temperature sensor, including a display, wherein a threaded block is fixedly connected to the middle of the bottom surface of the display;

[0008] A sensor is fixedly installed in the middle of the bottom surface of the display. The sensor is connected through a threaded block. A connecting sleeve is connected through the surface of the threaded block. A mounting plate is attached to the bottom surface of the connecting sleeve. The mounting plate is connected through the threaded block.

[0009] Also includes:

[0010] Limiting components are symmetrically arranged on both sides of the top surface of the mounting plate;

[0011] The limiting component includes a connecting plate that is fixedly connected to the mounting plate;

[0012] A limit frame is fixedly connected to one side of the top surface of the connecting plate.

[0013] Preferably, a pull rod is connected through the inside of the limiting frame, and a pull block is fixedly connected to one side of the top surface of the pull rod.

[0014] Preferably, a support plate is fixedly connected to the side surface of the pull rod away from the pull block, the bottom surface of the support plate is in contact with the connecting plate, and a locking rod is fixedly connected to the side surface of the support plate away from the pull rod.

[0015] Preferably, a spring is sleeved on the surface of the clamping rod, one side of the spring is fixedly connected to the support plate, and a limit sleeve is fixedly connected to the other side of the spring, with the clamping rod and the limit sleeve being connected through each other.

[0016] Preferably, the bottom surface of the limiting sleeve is fixedly connected to the connecting plate.

[0017] Preferably, fixing bolts are installed on both sides of the connecting plate.

[0018] Preferably, the connecting sleeve has several slots around its surface, which engage with the locking rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This precise mounting structure for an NTC pin-mount temperature sensor, through the setting of a mounting plate and fixing bolts, allows the sensor and display to be installed in a designated position on the device. Furthermore, the cooperation between the threaded block and the limiting component makes the installation and removal of the sensor and display more convenient, and also reduces the likelihood of damage to the sensor and display during installation. The specific details are as follows:

[0020] 1. By setting up a threaded block and a limiting component, when installing the sensor and display, pulling the pull block causes it to rotate, which in turn moves the pull rod. The movement of the pull rod then moves the support plate, which in turn moves the locking rod. This locking rod prevents it from obstructing the threaded block, allowing it to be placed inside the threaded groove of the device to be installed. Rotating the sensor and display causes the threaded block to rotate, allowing it to rotate within its matching threaded groove. After a certain number of rotations, the threaded block reaches the bottom of the groove. Simultaneously, loosening the pull block allows the locking rod to return to its original position under spring pressure, engaging with the slot on the connecting sleeve. This locking rod effectively limits the movement of the sensor and display, preventing unstable connection between the threaded block and the threaded groove, which could lead to the sensor and display falling and being damaged. This reduces the likelihood of sensor and display damage and, to some extent, lowers costs.

[0021] 2. By setting up a mounting plate and fixing bolts, the mounting plate can be installed in a designated position on the equipment. When disassembling the sensor and display, it is not necessary to disassemble the mounting plate. Simply separate the lever on the limit assembly from the slot on the connecting sleeve, and rotate the sensor and display to drive the threaded block to rotate. After rotating a certain number of times, the threaded block separates from the threaded groove on the equipment, thus separating the sensor and display. This improves the efficiency of disassembling and installing the sensor and display. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a precise mounting structure for an NTC pin-mount temperature sensor, including a display 1, a threaded block 2 fixedly connected to the middle of the bottom surface of the display 1; a sensor 3 fixedly mounted to the middle of the bottom surface of the display 1, the sensor 3 being connected through the threaded block 2, a connecting sleeve 4 being connected through the surface of the threaded block 2, and a mounting plate 5 being fitted to the bottom surface of the connecting sleeve 4, the mounting plate 5 being connected through the threaded block 2; further comprising: limit components 7 symmetrically arranged on both sides of the top surface of the mounting plate 5; wherein, the limit components 7 include a connecting plate 701 fixedly connected to the mounting plate 5; wherein, a limit bracket 702 is fixedly connected to one side of the top surface of the connecting plate 701, such as Figure 1-5As shown, by setting the mounting plate 5 and fixing bolts 6, the sensor 3 and display 1 can be installed in the designated position on the device. At the same time, when disassembling the sensor 3 and display 1, the cooperation between the threaded block 2 and the limiting component 7 makes the installation and disassembly of the sensor 3 and display 1 more convenient, and also reduces the possibility of damage to the sensor 3 and display 1 during installation.

[0030] A pull rod 703 is internally connected to the limiting bracket 702. A pull block 704 is fixedly connected to one side of the top surface of the pull rod 703. A support plate 705 is fixedly connected to the side of the pull rod 703 away from the pull block 704. The bottom surface of the support plate 705 is in contact with the connecting plate 701. A locking rod 706 is fixedly connected to the side of the support plate 705 away from the pull rod 703. A spring 707 is sleeved on the surface of the locking rod 706. One side of the spring 707 is fixedly connected to the support plate 705. A limiting sleeve 708 is fixedly connected to the other side of the spring 707. The locking rod 706 and the limiting sleeve 708 are internally connected. The bottom surface of the limiting sleeve 708 is fixedly connected to the connecting plate 701. Figure 4 , 5 As shown, by pulling the pull block 704, the rotation of the pull block 704 can drive the movement of the pull rod 703. The movement of the pull rod 703 can drive the movement of the support plate 705. The movement of the support plate 705 can drive the movement of the locking rod 706. The movement of the locking rod 706 ensures that it does not obstruct the threaded block 2, allowing the threaded block 2 to be placed inside the threaded groove of the equipment to be installed. Then, by rotating the sensor 3 and the display 1, the sensor 3 and the display 1 can drive the rotation of the threaded block 2, causing the threaded block 2 to rotate within its mating threaded groove. After a certain number of turns, the threaded block 2 rotates to the bottom of the threaded groove. At the same time, by loosening the pull block 704, the locking rod 706 returns to its original position under the action of the spring 707, thereby engaging the locking rod 706 with the locking groove 8 on the connecting sleeve 4. This allows the locking rod 706 to limit the sensor 3 and the display 1, thus preventing unstable connection between the threaded block 2 and the threaded groove, which could lead to the sensor 3 and the display 1 falling and being damaged. This reduces the possibility of damage to the sensor 3 and the display 1, thereby reducing the increase in cost to a certain extent. Meanwhile, the spring 707 is a compression spring in the prior art.

[0031] Fixing bolts 6 are installed on both sides of the connecting plate 701, such as... Figure 1As shown, the mounting plate 5 can be installed on the designated position on the equipment by means of the fixing bolt 6. When disassembling the sensor 3 and the display 1, it is not necessary to disassemble the mounting plate 5. It is only necessary to separate the locking rod 706 on the limiting assembly 7 from the locking groove 8 on the connecting sleeve 4. By rotating the sensor 3 and the display 1, the sensor 3 and the display 1 can drive the threaded block 2 to rotate. After rotating a certain number of times, the threaded groove on the equipment will separate from the threaded block 2, thereby separating the sensor 3 and the display 1 and improving the efficiency of disassembling and installing the sensor 3 and the display 1.

[0032] The surface of the connecting sleeve 4 has several slots 8 around its perimeter. The slots 8 engage with the locking rod 706. Figure 4 As shown, the engagement between the slot 8 and the lever 706 allows the lever 706 to limit the position of the sensor 3 and the display 1, thereby preventing unstable connection between the threaded block 2 and the threaded slot, which could lead to the sensor 3 and the display 1 falling off and being damaged. This reduces the possibility of damage to the sensor 3 and the display 1, thus reducing the increase in cost to a certain extent.

[0033] Working principle: Before using this NTC pin header temperature sensor for precise installation, it is necessary to check the overall condition of the device to ensure it can function normally. Figure 1 - Figure 5 As shown, when installing sensor 3 and display 1, pulling block 704 causes it to rotate, which in turn moves pull rod 703. The movement of pull rod 703 moves support plate 705, which in turn moves locking rod 706. This movement prevents locking rod 706 from obstructing threaded block 2, allowing it to be placed in the threaded groove of the device to be installed. Then, rotating sensor 3 and display 1 causes threaded block 2 to rotate, thus allowing the threaded block to be placed in the threaded groove of the device. The threaded block 2 rotates within its matching threaded groove. After rotating a certain number of times, the threaded block 2 rotates to the bottom of the threaded groove. At the same time, by loosening the pull block 704, the locking rod 706 returns to its original position under the action of the spring 707. This allows the locking rod 706 to engage with the locking groove 8 on the connecting sleeve 4, thereby limiting the sensor 3 and the display 1. This prevents unstable connection between the threaded block 2 and the threaded groove, which could lead to the sensor 3 and the display 1 falling and being damaged. This reduces the possibility of damage to the sensor 3 and the display 1, thus reducing the increase in cost to a certain extent.

[0034] Secondly, the mounting plate 5 can be installed in the designated position on the equipment by fixing bolt 6. When disassembling sensor 3 and display 1, it is not necessary to disassemble mounting plate 5. It is only necessary to separate the locking rod 706 on limit assembly 7 from the locking groove 8 on connecting sleeve 4. By rotating sensor 3 and display 1, sensor 3 and display 1 can drive threaded block 2 to rotate. After rotating a certain number of times, threaded block 2 separates from threaded groove on the equipment, thus separating sensor 3 and display 1. This improves the efficiency of disassembling and installing sensor 3 and display 1.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
