Description

Technical Field

[0001] This invention relates to the field of thermistor sensor technology, and in particular to a thermistor sensor with a ceramic support and fuse, and a method for manufacturing the same. Background Technology

[0002] A thermistor sensor is a temperature sensor designed based on the principle that resistance changes with temperature. It is made of a material with temperature-dependent resistance (usually a metal oxide) and is widely used in temperature measurement and control systems. With technological advancements, smart sensors have gained widespread attention and development in various application scenarios. Smart sensors not only possess the basic functions of traditional sensors, such as detecting physical quantities like temperature, humidity, and pressure, but also integrate microprocessors and wireless communication modules, enabling them to process, analyze, and transmit data, allowing for intelligent decision-making based on real-time monitoring.

[0003] The prior art publication CN112083222B provides a thermistor sensor that can operate in a temperature range of 0°C to 50°C, enabling it to measure microwave power outside of a laboratory environment.

[0004] While existing technologies have achieved laboratory-grade wide-temperature microwave power measurement, they can only operate in laboratory environments ranging from 0°C to 50°C. They lack protective structures designed for extreme high-temperature scenarios such as industrial furnaces, car cabins, and outdoor exploration, and therefore cannot achieve truly stable measurement across the entire temperature range outside of laboratory environments.

[0005] In summary, the existing technology lacks a technique suitable for extreme high temperatures for thermistor sensors. Summary of the Invention

[0008] Preferably, the outer wall of the conductor is provided with an insulating sleeve.

[0009] Preferably, a pressure silicone sealant is provided between the bottom end of the thermistor and the ceramic support.

[0010] Preferably, the thermally conductive ceramic sheet has a groove that is compatible with the thermistor, and the thermally conductive ceramic sheet has an assembly plane on one side.

[0011] Preferably, a spring is sleeved between the bottom end of the ceramic bracket and the fixed base.

[0012] Preferably, the protective component includes a fixed end, one end of which is fixedly connected to the fixed base at the position where the wire passes through. The outer wall of the fixed end has an external thread, and the outer wall of the fixed end has a connecting end. The inner wall of the connecting end has an internal thread, and the internal thread and the external thread are threadedly connected. An elastic sleeve is fixedly connected to the bottom of the connecting end. Positioning rods are rotatably connected to the inner walls on both sides of the connecting end. A gear is fixedly connected to the bottom of the positioning rod. A rack is meshed with one side of the gear. A slider is fixedly connected to one end of the rack. A guide rod is slidably fitted through the middle of the slider. The bottom end of the guide rod is fixedly connected to the inner wall of the connecting end. A second spring is fixedly connected to the bottom of the slider. The other end of the second spring is fixedly connected to the inner wall of the connecting end.

[0013] Preferably, the top end of the movable ring is fixedly connected to the bottom end of the elastic sleeve, a spring three is fixedly connected to the top end of the movable ring, the top end of the spring three is fixedly connected to the connecting end, a hanging ring is fixedly connected to the top of the movable ring, the hanging ring is movably engaged with the top end of the positioning rod, two slots are symmetrically formed on the inner wall of the movable ring, a push block is slidably fitted through the inner wall of the slot, a pressing block is fixedly connected to the outer end of the push block, and a rubber pad is fixedly connected to the bottom end of the movable ring.

[0014] Preferably, the sealing assembly includes a sealing block, the outer wall of which is adapted to the inner wall of the movable ring, and a locking block is slidably provided on both sides of the inner wall of the sealing block. A spring four is fixedly connected to the inner end of the locking block, and the other end of the spring four is fixedly connected to the inner wall of the sealing block. An inclined surface is provided on the outer end of the locking block, and the outer end of the locking block is movably engaged with the inner wall of the slot. The outer end of the locking block is also in movable contact with the push block.

[0015] A thermistor sensor with a ceramic support and a fuse, and a method for manufacturing the same, specifically including the following steps: S1. First, install the ceramic bracket and the fixed base; S2. Then, pass the wires at the bottom of the fuse and the thermistor through the ceramic bracket and the fixed base respectively, and place the fuse and the thermistor at the corresponding positions on the ceramic bracket. S3. Then press the thermally conductive ceramic sheet onto the opening at the top of the ceramic bracket to limit and conduct heat to the thermistor, and then put the temperature-sensing aluminum cover on the outside of the top of the ceramic bracket. S4. Then, put the protective components on the outside of the bottom of the wires, and then insert the sealing component into the movable ring to seal the opening of the protective component and protect the wires inside.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By setting up a sensor with a ceramic support, fuse, and thermistor, the ceramic support has sufficient insulation and anti-aging properties, can adapt to high-temperature working environments and has stable performance. The ceramic support and thermally conductive ceramic sheet wrap the thermistor, which has excellent heat transfer performance, making the thermistor have a wider heating area and more accurate and faster response, realizing a wider range of application scenarios for thermistor sensors. By providing an assembly plane on one side of the thermally conductive ceramic sheet, precise installation is achieved, enabling efficient automated production and cost savings. By providing pressure silicone at the bottom of the thermistor, the thermistor can be tightly fitted into the groove of the thermally conductive ceramic sheet, allowing for accurate temperature determination. By designing all wire connections of the fuse and thermistor without insulating sleeves, leaving them fully exposed within the slots of the ceramic support, effective insulation is achieved. By installing protective components at the external portions of the wires and insulating sleeves, the elastic sleeve can be stretched and unfolded under the action of spring three, blocking the outer side of the wires and insulating sleeves. At the same time, the sealing component can seal the opening at the end of the elastic sleeve, achieving further protection for the wires and insulating sleeves before sensor installation. During sensor transportation, storage, transfer, and installation, it can effectively prevent wire bending, scratching, and squeezing, prevent the insulating sleeve from being worn, torn, or falling off, ensure the integrity of the wires and insulating sleeves, and improve the product's factory qualification rate and reliability.

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figures 1-9 The thermistor sensor with ceramic support and fuse, and its manufacturing method, are shown. The sensor includes a fixed base 1, a ceramic support 2 on the fixed base 1, a fuse 3 and a thermistor 4 installed in the ceramic support 2, a thermally conductive ceramic plate 5 on the top of the ceramic support 2, a temperature-sensing aluminum cover 6 on the top of the ceramic support 2, multiple protective components 7 at the bottom of the fixed base 1, a movable ring 8 fixedly connected to the bottom of the protective components 7, a sealing component 9 inside the movable ring 8, and two wires 10 fixedly connected to the bottom of both the fuse 3 and the thermistor 4. The other end of the wires 10 passes through the ceramic support 2 and the fixed base 1 and extends downwards.

[0021] By setting up a sensor with a ceramic bracket 2, a fuse 3, and a thermistor 4, the ceramic bracket 2 has strong insulation and anti-aging properties, and can work stably at high temperatures. The ceramic bracket and the thermally conductive ceramic sheet 5 wrap around the thermistor 4, which has excellent heat transfer performance, making the thermistor 4 have a wider heating area and a more accurate and faster response, thus enabling the thermistor sensor to be used in a wider range of scenarios.

[0022] like Figure 2 As shown, an insulating sleeve 11 is provided on the outer wall of the conductor 10.

[0023] like Figure 5 As shown, a pressure silicone 401 is provided between the bottom end of the thermistor 4 and the ceramic support 2. The pressure silicone 401 is resistant to high and low temperatures and anti-aging, and can maintain stable elasticity and thermal conductivity throughout the entire service life of the sensor, and will not fail due to long-term use.

[0024] like Figure 5 As shown, a groove 501 is provided on the thermally conductive ceramic sheet 5. The groove 501 is adapted to the thermistor 4. The thermally conductive ceramic sheet 5 has an assembly plane on one side.

[0025] like Figure 4 As shown, a spring 201 is fitted between the bottom end of the ceramic bracket 2 and the fixed base 1.

[0026] like Figure 6 , Figure 7 As shown, the protective component 7 includes a fixed end 701. One end of the fixed end 701 is fixedly connected to the fixed base 1 at the position where the wire 10 passes through. The outer wall of the fixed end 701 has an external thread 702. The outer wall of the fixed end 701 has a connecting end 703. The inner wall of the connecting end 703 has an internal thread 704. The internal thread 704 is threadedly connected to the external thread 702. An elastic sleeve 705 is fixedly connected to the bottom end of the connecting end 703. Both inner walls of the connecting end 703 are rotatably connected. A positioning rod 706 is provided, with a gear 707 fixedly connected to its bottom end. A rack 708 is meshed with the gear 707 on one side, and a slider 709 is fixedly connected to one end of the rack 708. A guide rod 710 is slidably fitted through the middle of the slider 709, and its bottom end is fixedly connected to the inner wall of the connecting end 703. A second spring 711 is fixedly connected to the bottom end of the slider 709, and its other end is fixedly connected to the inner wall of the connecting end 703. The positioning rod 706 can limit the movement of the movable ring 8, facilitating the connection and installation of the exposed end of the wire 10. The bottom end of the positioning rod 706 is limited by the inner wall of the connecting end 703, allowing it to rotate only by less than 90 degrees.

[0027] The external thread 702 and the internal thread 704 have high thread precision and tight meshing, enabling quick assembly and disassembly of the connecting end 703 and the fixed end 701, facilitating subsequent maintenance and replacement of the wire 10. The elastic sleeve 705 is made of wear-resistant, tensile-resistant, and anti-aging soft rubber material, which can freely expand and contract to adapt to the exposed part of the wire 10 of different lengths, and fully wraps the wire 10 and the insulating sleeve 11, playing a role in preventing bending, scratching, and squeezing. The positioning rod 706 is made of high-strength steel, can rotate flexibly, and has a hook structure at the top, which can accurately engage with the hanging ring 802 of the movable ring 8 to limit and fix the movable ring 8, preventing the elastic sleeve 705 from expanding and contracting arbitrarily.

[0028] like Figure 8 As shown, the top end of the movable ring 8 is fixedly connected to the bottom end of the elastic sleeve 705. A spring 801 is fixedly connected to the top end of the movable ring 8, and the top end of the spring 801 is fixedly connected to the connecting end 703. A hanging ring 802 is fixedly connected above the movable ring 8, and the hanging ring 802 is movably engaged with the top end of the positioning rod 706. Two slots 803 are symmetrically formed on the inner wall of the movable ring 8. A push block 804 is slidably fitted through the inner wall of the slot 803. A pressing block 805 is fixedly connected to the outer end of the push block 804. A rubber pad 806 is fixedly connected to the bottom end of the movable ring 8. The rubber pad 806, in conjunction with the spring 801, can seal the connection when the wire 10 is connected to the main board.

[0029] The movable ring 8 is made of lightweight, wear-resistant plastic, with a robust structure. It can extend and retract the elastic sleeve 705, while also providing an installation carrier for the sealing assembly 9. The spring 801 is made of high-elasticity spring steel, normally under tension, and can pull the movable ring 8 downwards, causing the elastic sleeve 705 to extend and fully enclose the wire 10 and insulating sleeve 11, ensuring effective protection. The hanging ring 802 is welded and fixed to the movable ring 8, resulting in a sturdy structure. The size of the slot 803 precisely matches the locking block 902 of the sealing assembly 9, enabling quick locking and fixing of the sealing assembly 9, facilitating its assembly and disassembly. The push block... 804 and the pressing block 805 are integrally molded and made of wear-resistant plastic material, making it easy for operators to press. Pushing the push block 804 squeezes the locking block 902 to release the sealing component 9, making operation convenient. The rubber pad 806 is made of soft and wear-resistant rubber material, which has good sealing and cushioning properties. When the wire 10 is connected to the motherboard, the rubber pad 806 adheres to the surface of the motherboard and, together with the elastic pressure of the spring 801, seals the connection between the wire 10 and the motherboard, preventing dust and moisture from entering the connection and avoiding problems such as poor contact and short circuits. At the same time, it plays a cushioning role, reducing vibration and wear at the connection.

[0030] like Figure 9As shown, the sealing assembly 9 includes a sealing block 901. The outer wall of the sealing block 901 is adapted to the inner wall of the movable ring 8. Both sides of the inner wall of the sealing block 901 are slidably fitted with locking blocks 902. The inner end of the locking block 902 is fixedly connected to a spring 903. The other end of the spring 903 is fixedly connected to the inner wall of the sealing block 901. The outer end of the locking block 902 has an inclined surface 904. The outer end of the locking block 902 is movably engaged with the inner wall of the slot 803. The outer end of the locking block 902 is in movable contact with the push block 804.

[0031] The outer wall of the sealing block 901 is made of soft sealing rubber material, which fits tightly against the inner wall of the movable ring 8. This seals the end opening of the elastic sleeve 705, preventing dust and moisture from entering the interior of the elastic sleeve 705 and protecting the wire 10 and the insulating sleeve 11. The locking block 902 is made of wear-resistant plastic material, and the beveled surface 904 at the outer end allows the locking block 902 to automatically retract when the sealing block 901 is inserted into the movable ring 8. After insertion, the spring 903 resets, pushing the locking block 902 out and locking it into the slot 803, achieving quick fixation of the sealing block 901 without the need for additional fasteners, making operation convenient. The spring 903 is made of high-elasticity spring steel and is in an extended state under normal conditions, ensuring that the locking block 902 is firmly engaged with the slot 803 and preventing the sealing block 901 from falling off.

[0032] A thermistor sensor with a ceramic support and a fuse, and a method for manufacturing the same, specifically including the following steps: S1. First, install the ceramic bracket 2 and the fixed base 1; S2. Then, pass the wires 10 at the bottom of the fuse 3 and the thermistor 4 through the ceramic bracket 2 and the fixed base 1 respectively, and place the fuse 3 and the thermistor 4 at the corresponding positions on the ceramic bracket 2. S3. Then press the thermally conductive ceramic sheet 5 onto the opening at the top of the ceramic bracket 2 to limit and conduct heat to the thermistor 4, and then put the temperature-sensing aluminum cover 6 on the outside of the top of the ceramic bracket 2. S4. Then, the protective components 7 are respectively placed on the outside of the bottom end of the wire 10, and the sealing components 9 are inserted into the movable ring 8 to seal the opening of the protective components 7 and protect the wire 10 inside.

[0033] Working principle: First, install the sensor. When it is necessary to connect the wire 10 to the external motherboard, the operator presses the pressing blocks 805 on both sides of the movable ring 8. The pressing blocks 805 drive the push block 804 to move inward. The push block 804 squeezes the locking block 902, causing the locking block 902 to compress the spring 903, disengage from the slot 803, release the fixing of the sealing assembly 9, and remove the sealing block 901 from the movable ring 8. Then push the movable ring 8 upwards. When the hanging ring 802 on the movable ring 8 contacts the positioning rod 706, it will squeeze the positioning rod 706, causing the positioning rod 706 to retract. When the hanging ring 802 passes the positioning rod 706, the spring 711 will drive the rack 708 connected to the slider 709 to move upwards, thereby pushing the top of the positioning rod 706 connected to the gear 707 to rotate and move out. At this time, release the movable ring 8. The downward-moving hanging ring 802 will be blocked by the positioning rod 706 and stop moving downwards, so that the end of the wire 10 is exposed and can be installed. After installation, push the movable ring 8 upwards and press the positioning rod 706, then release the movable ring 8 so that the hanging ring 802 can move downwards smoothly. The spring 801 returns to its original position, driving the movable ring 8 to move downwards. The elastic sleeve 705 unfolds again, wrapping the connection between the wire 10 and the motherboard. The rubber pad 806 at the bottom of the movable ring 8 adheres to the surface of the motherboard. With the elastic pressure of the spring 801, the connection is sealed to prevent dust and moisture from entering and to ensure a stable connection.

[0034] Secondly, during the temperature detection process, when the temperature of the device under test changes, the temperature-sensing aluminum cover 6 quickly absorbs the external temperature and transfers it to the thermally conductive ceramic sheet 5. The thermally conductive ceramic sheet 5, with its excellent thermal conductivity, uniformly and quickly transfers the temperature to the thermistor 4. Because the thermistor 4 is tightly attached to the groove 501 of the thermally conductive ceramic sheet 5 via pressure silicone 401, with no contact gaps, the thermistor 4 can quickly respond to temperature changes, and its resistance value changes accordingly with the temperature. The thermistor 4 transmits the resistance value change signal to the external control circuit through the wire 10. The external control circuit accurately calculates the actual temperature of the device under test based on the resistance value change, achieving accurate temperature detection. The ceramic bracket 2, made of highly insulating material, separates the fuse 3 from the thermistor 4, preventing mutual interference. Simultaneously, the insulation performance of the ceramic bracket 2 ensures that short circuits do not occur at the connection point of the wire 10, guaranteeing stable transmission of the temperature detection signal. The single-sided mounting plane of the thermally conductive ceramic sheet 5 ensures precise installation, further improving the consistency and accuracy of temperature detection.

[0035] Then, when an abnormal situation such as overload or short circuit occurs in the external circuit, the current in the circuit will increase sharply, and the fuse 3 will melt quickly, cutting off the circuit and preventing excessive current from flowing through the thermistor 4 and the external control circuit. This prevents the thermistor 4 from being damaged and the external circuit from being burned out, thus playing a role in circuit protection and ensuring the safety of the sensor and external equipment. The connection between the fuse 3 and the wire 10 is exposed in the groove of the ceramic bracket 2. The excellent insulation performance of the ceramic bracket 2 is used to prevent short circuits at the connection, ensuring that the fuse 3 can play its protective role normally. At the same time, the high temperature resistance of the ceramic bracket 2 can prevent the high temperature generated when the fuse 3 melts from damaging the bracket itself.
