Description

Technical Field

[0001] The utility model relates to the technical field of thermistors, in particular to a thermistor component that is easy to install and replace. Background Art

[0002] A thermistor is a sensor resistor whose resistance value changes with temperature. It is a semiconductor device and a commonly used component in temperature sensors. It is mainly used to measure equipment and ambient temperature.

[0003] Existing thermistors mainly fix their pins to the circuit by soldering. Therefore, when the thermistor is damaged and needs to be replaced, professional staff are required to hold a soldering iron to melt the solder, then unplug the thermistor, clean the melted solder, and then insert a new thermistor into the circuit and fix it by soldering. The operation requirements are high, and if the professionalism is not enough, it is easy to burn the surrounding components or the pins of the components, which is not convenient for convenient and quick installation and replacement. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a thermistor assembly that is easy to install and replace, so as to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a thermistor assembly that is easy to install and replace, comprising a shell, first pins connected to both sides of the bottom of the shell, a bidirectional screw rod passing through the outer surface of the shell, and limit plates connected to both ends of the bidirectional screw rod, a first adjustment plate and a second adjustment plate connected to the top of the bidirectional screw rod respectively, and a first clamping plate connected to both sides of the first adjustment plate, and a second clamping plate connected to both sides of the second adjustment plate.

[0006] By adopting the above technical solution, when the thermistor needs to be disassembled, the limit plate is rotated by the Allen wrench to rotate the bidirectional screw rod. After the bidirectional screw rod rotates, the first adjustment plate and the second adjustment plate are driven to move away from each other, so that the first clamping plate and the second clamping plate move away from each other and end the clamping of the second pin, and the thermistor body can be removed at this time; the new thermistor body is placed on the top of the shell so that the second pin is inserted into the inside of the shell, and then the limit plate is rotated in the opposite direction by the Allen wrench to reverse the bidirectional screw rod. After the bidirectional screw rod is reversed, the first adjustment plate and the second adjustment plate are driven to move closer to each other, so that the first clamping plate and the second clamping plate move closer to each other to clamp the second pin, and the first clamping plate and the second clamping plate are both made of copper material, which makes it easy for the thermistor body to pass through the second pin, the first clamping plate, the second clamping plate and the first pin and the circuit to realize current flow.

[0007] Furthermore, a hexagonal groove is formed at one end of the limiting plate.

[0008] By adopting the technical scheme, when the staff needs to disassemble the thermistor main body, the hexagonal wrench is used to rotate the limiting disc, so that the bidirectional screw rod is rotated.

[0009] Further, the first adjusting plate and the second adjusting plate are in threaded connection with the bidirectional screw rod, and the first adjusting plate, the second adjusting plate, the first clamping plate and the second clamping plate are in sliding connection with the shell.

[0010] By adopting the technical scheme, after the bidirectional screw rod is rotated, the first adjusting plate and the second adjusting plate are driven to move away from each other, so that the first clamping plate and the second clamping plate move away from each other to end the clamping of the second pin, and at this time, the thermistor main body can be taken down.

[0011] Further, the first clamping plate and the second clamping plate are made of copper material.

[0012] By adopting the technical scheme, the first clamping plate and the second clamping plate are made of copper material, so as to facilitate the current circulation between the thermistor main body and the circuit.

[0013] Further, the shell, the first adjusting plate and the second adjusting plate are made of PC material.

[0014] By adopting the technical scheme, the shell, the first adjusting plate and the second adjusting plate are made of PC material, which has good heat resistance, aging resistance, structural strength and insulation, so as to be used for a long time and avoid the current disorder caused by the current received from the first clamping plate and the second clamping plate.

[0015] Further, the thermistor main body is connected to the top of the shell, and the second pin is connected to the bottom of the thermistor main body.

[0016] By adopting the technical scheme, the thermistor main body realizes the current circulation with the circuit through the second pin, the first clamping plate, the second clamping plate and the first pin.

[0017] Further, the second pin is detachably connected with the first clamping plate and the second clamping plate.

[0018] By adopting the technical scheme, after the bidirectional screw rod is reversed, the first adjusting plate and the second adjusting plate are driven to move close to each other, so that the first clamping plate and the second clamping plate move close to each other to clamp the second pin.

[0019] Further, the thermistor main body is fixed with a positioning block at the bottom, and a limiting plate is connected between the two second clamping plates.

[0020] By adopting the above technical solution, after the thermistor body is placed on the shell, the positioning block enters the shell. At the same time that the first clamping plate and the second clamping plate approach each other to clamp the second pin, the limit plate will move to the top of the positioning block for limiting, thereby reducing the phenomenon of the thermistor body being forcibly pulled out and causing wear of the second pin, the first clamping plate and the second clamping plate.

[0021] Furthermore, the cross section of the positioning block is in an "L" shape or an inverted "T" shape, and the limiting plate is detachably connected to the positioning block.

[0022] By adopting the above technical solution, after the thermistor body is placed on the shell, the positioning block enters the shell, and the limiting plate moves to the top of the positioning block for limiting.

[0023] Furthermore, the limiting plate is made of PC material.

[0024] By adopting the above technical solution, the limiting plate is made of PC material, which has good heat resistance, aging resistance, structural strength and insulation, so that it can be used for a long time and avoid receiving current in the direction of the first clamping plate and the second clamping plate, causing current disorder and short circuit.

[0025] In summary, the present invention has the following beneficial effects:

[0026] The second clamping plate and the second clamping plate are respectively driven to move the first clamping plate and the second clamping plate away from each other, thereby clamping the second pin and the second clamping plate together.

[0027] 2. The utility model provides a positioning block and a limiting plate. After the thermistor body is placed on the housing, the positioning block enters the interior of the housing. While the first clamping plate and the second clamping plate approach each other to clamp the second pin, the limiting plate will move to the top of the positioning block for limiting. This reduces the phenomenon of the thermistor body being forcibly pulled out and causing wear of the second pin, the first clamping plate and the second clamping plate; and improves the stability after installation.

[0037] Referring to Figures 1-3 In the above embodiment, the shell 1 top is connected with the thermistor body 3, the thermistor body 3 bottom both sides are connected with the second pin 4, the thermistor body 3 realizes the circulation of current through the second pin 4, the first clamping plate 9, the second clamping plate 10 and the first pin 2, so as to facilitate the thermistor body 3 to measure the temperature.

[0038] Example two:

[0039] On the basis of the above embodiment one, in order to improve the stability after installation, now through the following setting.

[0040] Referring to Figures 2-4 In the above embodiment, the thermistor body 3 bottom is fixed with the positioning block 11, the positioning block 11 cross section is "L" or inverted "T", the two second clamping plates 10 are connected with the limit plate 12, the limit plate 12 is connected with the positioning block 11, the limit plate 12 is made of PC material, the staff puts the new thermistor body 3 on the shell 1 top, at the same time, the positioning block 11 enters the shell 1 inside, at the same time, the first clamping plate 9 and the second clamping plate 10 clamp the second pin 4, the limit plate 12 will be displaced to the top of the positioning block 11 for limiting, so as to reduce the phenomenon that the second pin 4, the first clamping plate 9 and the second clamping plate 10 are worn out due to the violent pulling out of the thermistor body 3.

[0041] The implementation principle of the present utility model is as follows: first, the first pin 2 is fixed to the circuit by soldering with an electric soldering iron. Since the first clamping plate 9 and the second clamping plate 10 are both made of copper material, the thermistor body 3 is connected to the circuit through the second pin 4, the first clamping plate 9, the second clamping plate 10 and the first pin 2 to realize current circulation, thereby facilitating the thermistor body 3 to measure the temperature. The housing 1, the first adjustment plate 7, the second adjustment plate 8 and the limit plate 12 are all made of PC material, which has good heat resistance, aging resistance, structural strength and insulation, thereby ensuring long-term use and preventing current disturbance and short circuit caused by current received in the direction of the first clamping plate 9 and the second clamping plate 10.

[0042] When the damaged thermistor body 3 needs to be disassembled later, the staff rotates the limit plate 5 with the Allen wrench, thereby rotating the bidirectional screw 6. After the bidirectional screw 6 rotates, the first adjustment plate 7 and the second adjustment plate 8 are driven to move away from each other, so that the first clamping plate 9 and the second clamping plate 10 move away from each other to end the clamping of the second pin 4, and the limit plate 12 moves away from the positioning block 11. At this time, the staff can remove the thermistor body 3;

[0043] The staff places the new thermistor body 3 on the top of the shell 1, and the positioning block 11 enters the inside of the shell 1, and the second pin 4 is inserted into the inside of the shell 1. Then the staff uses the Allen wrench to reverse the limit plate 5, so that the two-way screw 6 is reversed. After the two-way screw 6 is reversed, it drives the first adjustment plate 7 and the second adjustment plate 8 to approach each other, so that the first clamping plate 9 and the second clamping plate 10 are close to each other to clamp the second pin 4. While the first clamping plate 9 and the second clamping plate 10 are close to each other to clamp the second pin 4, the limit plate 12 will move to the top of the positioning block 11 for limiting, thereby reducing the phenomenon of the thermistor body 3 being violently pulled out and causing wear of the second pin 4, the first clamping plate 9 and the second clamping plate 10.
