Description

Technical Field

[0001] The utility model relates to the technical field of thermistors, in particular to a power type NTC thermistor. Background Art

[0002] NTC thermistors are thermally sensitive ceramic components made primarily from transition metal oxides using an electronic ceramic process. Resistors are often used on circuit boards. When a circuit board is damaged, the resistor may not be damaged, allowing for secondary use, saving resources and costs. However, resistors removed from circuit boards may lack suitable storage space.

[0003] A Chinese patent application, CN202121034822.3, discloses a high-temperature NTC thermistor. The key technical solution is as follows: The high-temperature NTC thermistor provided by this utility model incorporates a barrier layer between the electrode layer and the ceramic substrate to effectively block the penetration and migration of Ag ions, thereby improving the long-term stability of the NTC thermistor. By further adjusting the thickness of the barrier layer, the penetration and migration of Ag ions can be further blocked, ensuring the long-term stability of the NTC thermistor.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: resistors are often used on circuit boards. When the circuit board is damaged, the resistors may not be damaged. Such resistors can often be reused to save resources and costs. However, the resistors removed from the circuit board may not have suitable storage space. When multiple resistor bodies are stacked together in a disorderly manner, the stacking positions of the resistor bodies are messy, and the connecting pins between the multiple resistor bodies are entangled and difficult to disassemble and separate, resulting in damage to the connecting pins or the resistor bodies, affecting the problem of the resistor bodies being put into use again; therefore, a power type NTC thermistor is proposed to address the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art in that the connecting pins between the resistor bodies are entangled and difficult to disassemble and separate, thereby causing damage to the connecting pins or the resistor body, affecting the re-use of the resistor body, and to propose a power type NTC thermistor.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a power type NTC thermistor, including a resistor body, two connecting feet installed in the resistor body, the arc surface of the resistor body is fixedly connected to a connecting block, the upper surface of the connecting block is fixedly connected to a round rod, the arc surface of the round rod is slidably connected to a circular plate, and the surface of the circular plate is fixedly connected to a semicircular buckle.

[0007] The effect achieved by the above components is: it is convenient to hang or store multiple resistor bodies in a unified manner, avoiding the situation where multiple resistor bodies are stacked together in a messy manner, resulting in a messy stacking position of the resistor bodies, and the connecting pins between the multiple resistor bodies are entangled and difficult to disassemble and separate, thereby causing the connecting pins or the resistor bodies to be damaged, affecting the resistor bodies from being put into use again, thereby improving the practicality of the device.

[0008] Preferably, a rotating plate is fixedly connected to the upper surface of the circular plate, and the rotating plate is rotatably connected to the arc surface of the round rod.

[0009] The effect achieved by the above components is: the rotating plate achieves the effect of adjusting the hanging angle of the semicircular buckle, avoiding the situation where the staff hangs the resistor body with a small hanging angle of the hook and the large size of the resistor body, resulting in obstruction by the arc surface of the resistor body during hanging, or collision between the arc surfaces of multiple resistor bodies, causing the semicircular buckle to be difficult to adapt to most hooks, thereby affecting the hanging of the resistor body.

[0010] Preferably, the arc surfaces of the two connecting legs are both covered with support sleeves, the upper surfaces of the two support sleeves are fixedly connected with support plates, and the material of the support sleeves is rubber.

[0011] The effect achieved by the above components is: it achieves the effect of supporting the resistor body, and avoids the situation where the staff solders the connecting pins of the resistor body to the circuit board. Due to the high height of the connecting pins, the resistor body becomes tilted due to gravity factors after long-term use, causing the connecting pins to bend, thereby affecting the normal use of the resistor body.

[0012] Preferably, an L-shaped rod is slidably connected to each of the two support sleeves, one end of each of the two L-shaped rods is fixedly connected to a sliding plate, and a long rod is slidably inserted into the two sliding plates.

[0013] The effect achieved by the above components is: it is convenient to expand the support sleeve for easy sliding, and avoids the situation where when the staff needs to adjust the height of the support sleeve, the support sleeve has good closure, the force on the connecting foot is large, and it is difficult to adjust quickly, resulting in the staff not using a lot of force to move the position of the support sleeve, which may cause excessive force and damage to the connecting foot.

[0014] Preferably, both ends of the long rod are fixedly connected to a limit plate, and the size of the limit plate is larger than that of the long rod.

[0015] The effect achieved by the above components is that the limit plate reaches the maximum distance that limits the sliding plate from sliding on the arc surface of the long rod, thereby preventing the sliding plate from detaching from the arc surface of the long rod due to the strong pulling force when the staff pulls the sliding plate.

[0016] Preferably, one side of the support plate is fixedly connected to an L-shaped ruler plate, the L-shaped ruler plate is slidably connected to one side of the resistor body, the side of the resistor body close to the L-shaped ruler plate is fixedly connected to a U-shaped plate, and the surface of the L-shaped ruler plate is slidably connected to the U-shaped plate.

[0017] The effect achieved by the above components is that the L-shaped ruler plate makes it convenient for staff to roughly measure the remaining length of the connecting pin, so as to calculate in advance whether the resistor body can be reused or reasonably plan the length of the connecting pin each time.

[0018] Preferably, a trapezoidal block is fixedly connected to one side of the resistor body close to the U-shaped plate, a short rod is fixedly connected to the surface of the trapezoidal block, and a scale is fixedly connected to the arc surface of the short rod.

[0019] The effect achieved by the above components is that the ruler improves the measurement accuracy of the connection pins, so that the staff can more accurately calculate the number of times the resistor body is used, thereby better saving costs.

[0020] In summary, the beneficial effects of the present invention are as follows:

[0021] In the present invention, the effect of facilitating the unified hanging or unified storage of multiple resistor bodies is achieved, avoiding the situation where multiple resistor bodies are randomly stacked together, resulting in a messy stacking position of the resistor bodies, and the connecting pins between the multiple resistor bodies are entangled and difficult to disassemble and separate, thereby causing the connecting pins or the resistor bodies to be damaged, affecting the resistor bodies from being put into use again, thereby improving the practicality of the device.

[0027] Reference Figure 1-4As shown, the utility model provides a technical solution: a power type NTC thermistor, comprising a resistor body 1, two connecting pins 2 are installed in the resistor body 1, the arc surface of the resistor body 1 is fixedly connected to a connecting block 3, the upper surface of the connecting block 3 is fixedly connected to a round rod 4, the arc surface of the round rod 4 is slidably connected to a round plate 5, and the surface of the round plate 5 is fixedly connected to a semicircular buckle 6. When the staff needs to put away the resistor bodies 1 for storage, the semicircular buckle 6 is hung on a hook or a rope is passed through the semicircular buckle 6. At this time, the effect of facilitating the unified hanging or unified storage of multiple resistor bodies 1 is achieved, avoiding the multiple resistor bodies 1 being randomly stacked together, resulting in a messy stacking position of the resistor bodies 1 and entanglement of the connecting pins 2 between the multiple resistor bodies 1. The rotatable plate 7 is fixedly connected to the upper surface of the circular plate 5, and the rotatable plate 7 is rotatably connected to the arc surface of the round rod 4. When the staff needs to hang the resistor body 1, or use a rope to store it in series, the rotatable plate 7 is rotated to make the rotatable plate 7 rotate on the arc surface of the round rod 4. At the same time, the rotatable plate 7 drives the circular plate 5 to rotate, and the circular plate 5 drives the semicircular buckle 6 to rotate until the semicircular buckle 6 is rotated to a suitable angle. At this time, the rotatable plate 7 achieves the effect of adjusting the hanging angle of the semicircular buckle 6, avoiding the staff hanging the resistor body 1. The hanging angle of the hook is small, and the size of the resistor body 1 is large. The arc surface of the resistor body 1 creates an obstruction, or collisions occur between the arc surfaces of multiple resistor bodies 1, causing the semicircular buckle 6 to be difficult to adapt to most hooks, thereby affecting the suspension of the resistor body 1. The arc surfaces of the two connecting feet 2 are both covered with support sleeves 8, and the upper surfaces of the two support sleeves 8 are fixedly connected with support plates 9. The material of the support sleeves 8 is rubber. When the staff uses the resistor body 1, the connecting feet 2 of the resistor body 1 are welded to the circuit board. At this time, the support sleeves 8 and the support plates 9 achieve the effect of supporting the connecting feet 2, thereby achieving the effect of supporting the resistor body 1, avoiding the staff from using the resistor body 1 for a long time due to gravity factors when welding the connecting feet 2 of the resistor body 1 to the circuit board due to the high height of the connecting feet 2. When the two L-shaped rods 10 are tilted, the connecting legs 2 are bent, which affects the normal use of the resistor body 1. The two support sleeves 8 are slidably connected with L-shaped rods 10, and one end of the two L-shaped rods 10 is fixedly connected with a sliding plate 11. Long rods 12 are slidably inserted in the two sliding plates 11. When the staff needs to adjust the position of the support sleeve 8, the two sliding plates 11 are pulled away from each other. At this time, the two sliding plates 11 slide away from each other on the arc surface of the long rod 12. At the same time, the two sliding plates 11 drive the two L-shaped rods 10 to move away from each other. At this time, the two L-shaped rods 10 stretch one side of the support sleeve 8. At this time, press the support plate 9 upward or downward, and the support plate 9 drives the support sleeve 8 to slide on the arc surface of the two connecting legs 2.The support sleeve 8 is preferably adjusted to a suitable position, at which time the support sleeve 8 is easily opened and slid, which avoids the need for the worker to adjust the height of the support sleeve 8. The support sleeve 8 has a good closure, and the force on the connecting foot 2 is large, which is difficult to adjust quickly. As a result, the worker does not use a large amount of force to move the position of the support sleeve 8, which may cause excessive force and damage to the connecting foot 2. Both ends of the long rod 12 are fixedly connected to the limit plate 13. The size of the limit plate 13 is larger than the size of the long rod 12. When the worker When the staff pulls the sliding plates 11 in opposite directions, the two sliding plates 11 slide away from each other on the arc surface of the long rod 12. At this time, the limit plate 13 reaches the maximum distance to limit the sliding plates 11 from sliding on the arc surface of the long rod 12, avoiding the situation where the sliding plates 11 are separated from the arc surface of the long rod 12 due to the strong pulling force when the staff pulls the sliding plates 11. An L-shaped ruler 14 is fixedly connected to one side of the support plate 9. The L-shaped ruler 14 is slidably connected to one side of the resistor body 1. The side of the resistor body 1 close to the L-shaped ruler 14 is fixed A U-shaped plate 15 is fixedly connected, and the surface of the L-shaped ruler 14 is slidably connected to the U-shaped plate 15. When the staff removes the connecting foot 2 from the resistor body 1 from the circuit board, the staff wants to store the resistor body 1 for secondary use. The support sleeve 8 is moved, and the support sleeve 8 drives the support plate 9 to move. The support plate 9 drives the L-shaped ruler 14 to slide in the U-shaped plate 15 until the support sleeve 8 is moved to the end of the connecting foot 2. At this time, the L-shaped ruler 14 achieves the effect of making it convenient for the staff to roughly measure the remaining length of the connecting foot 2, so as to facilitate the early measurement of the resistor body. To determine whether the connecting leg 1 can be reused or to rationally plan the length of each connection leg 2, a trapezoidal block 16 is fixedly connected to the side of the resistor body 1 near the U-shaped plate 15. A short rod 17 is fixedly connected to the surface of the trapezoidal block 16, and a scale 18 is fixedly connected to the arc surface of the short rod 17. When the staff measures the remaining length of the connecting leg 2, the scale 18 points to the scale of the L-shaped ruler plate 14. At this time, the scale 18 improves the measurement accuracy of the connecting leg 2, allowing the staff to more accurately calculate the number of times the resistor body 1 can be used multiple times, thereby further saving costs.

[0028] Working principle: the resistor body 1 is often installed on a circuit board for use. After one use, the resistor body 1 may not be damaged and can be reused. At this time, the connecting pin 2 of the resistor body 1 can be cut off from the circuit board. Before cutting, pull the sliding plate 11 to make the two sliding plates 11 slide away from each other on the arc surface of the long rod 12. At the same time, the two sliding plates 11 drive the two L-shaped rods 10 to move away from each other. At this time, the two L-shaped rods 10 will open one side of the support sleeve 8. At this time, press the support plate 9 downward. The support plate 9 drives the support sleeve 8 to slide on the arc surface of the two connecting pins 2. At the same time, the support plate 9 drives the L-shaped ruler 14 to slide in the U-shaped plate 15 until the support sleeve 8 is moved to the very end of the connecting pin 2. At this time, release the sliding plate 11. The elastic force of the support sleeve 8 causes the support sleeve 8 to be re-covered on the connecting pin 2. At this time, along the support sleeve 8 The bottom of the connecting foot 2 is cut off, and the ruler 18 points to the scale of the L-shaped ruler plate 14. At this time, the staff can accurately observe the length of the remaining connecting foot 2, and at the same time, the staff rotates the rotating plate 7 to make the rotating plate 7 rotate on the arc surface of the round rod 4. At the same time, the rotating plate 7 drives the circular plate 5 to rotate, and the circular plate 5 drives the semicircular buckle 6 to rotate until the semicircular buckle 6 is rotated to a suitable angle, and the semicircular buckle 6 is hung on the hook, or a rope is used to pass through the semicircular buckle 6. At this time, the effect of facilitating the unified hanging or unified storage of multiple resistor bodies 1 is achieved, avoiding the messy stacking of multiple resistor bodies 1, resulting in a messy stacking position of the resistor bodies 1, and the connecting feet 2 between the multiple resistor bodies 1 are entangled, which is difficult to disassemble and separate, thereby causing the connecting feet 2 or the resistor body 1 to be damaged, affecting the situation where the resistor body 1 is put into use again, thereby improving the practicality of the device.
