Description

Technical Field

[0001] This utility model relates to the field of thermistor manufacturing technology, and in particular to a thermistor bending and forming assembly structure. Background Technology

[0002] A thermistor is a type of sensor resistor whose resistance changes with temperature. Based on their temperature coefficient, they are classified into positive temperature coefficient (PTC) thermistors and negative temperature coefficient (NTC) thermistors. The resistance of a PTC thermistor increases with increasing temperature, while the resistance of a NTC thermistor decreases with increasing temperature; both are semiconductor devices.

[0003] In the existing technology, the leads of thermistors are straight after production. However, in actual installation and application, the leads need to be bent depending on the installation point. Currently, the leads are bent manually using tweezers. This method results in poor accuracy in bending angle and distance, and further adjustments are required during assembly, making assembly inconvenient. Utility Model Content

[0010] Preferably, a side groove is provided on one side of the upper end of the end cap, and the side groove is connected to the second end groove.

[0011] Preferably, a second limiting block is provided at the lower end of the pressure block, the second limiting block is fixedly connected to the assembly frame, a threaded hole is provided in the middle of one side of the assembly cavity, a threaded rod is threadedly connected inside the threaded hole, and a limit plate is fixedly connected to one end of the threaded rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting the pressure block, when assembling the thermistor, the lead of the thermistor can be inserted into the second end slot and placed in the middle slot. Then, by pressing the pressure block, the lead can be bent quickly. In this way, the distance control is more precise and convenient to use, without the need for secondary adjustment.

[0014] 2. In this utility model, the side groove can restrict the end of the thermistor, ensuring stability during bending.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a thermistor bending and forming assembly structure, including a housing mechanism 1 and a bending mechanism 2. The housing mechanism 1 includes an assembly frame 11, with an assembly cavity 17 in the middle. The bending mechanism 2 includes a pressure block 21, which is slidably connected to the assembly cavity 17. The upper end of the assembly frame 11 has a second end groove 111. The middle of one side of the pressure block 21 has a central groove 28. The upper end of one side of the pressure block 21 has an installation groove 29. A roller 26 is rotatably connected inside the installation groove 29. A first limiting block 15 is provided at the upper end of the pressure block 21, which is fixedly connected to the assembly frame 11. Both the upper ends of the pressure block 21 and the first limiting block 15 have a first end groove 14.

[0025] The specific settings and functions of this embodiment will be described in detail below. With the setting of the pressure block 21, when assembling the thermistor, the pins of the thermistor can be inserted into the second terminal slot 111 and placed in the middle slot 28. Then, the pins can be quickly bent by pressing the pressure block 21. In this way, the distance control is more precise and convenient to use, without the need for secondary adjustment.

[0026] Example 2: Figure 1 - Figure 4As shown, both sides of the pressure block 21 are provided with sliding grooves 23, and a limiting slide 22 is slidably connected between the two sliding grooves 23. Two guide rods 110 are fixedly connected to both sides of the upper middle part of the assembly cavity 17, and a guide rod 18 is fixedly connected to the lower middle part of the assembly cavity 17. Both the guide rod 18 and the guide rod 110 are slidably connected to the pressure block 21. Springs 19 are provided on the outer sides of both the guide rod 18 and the guide rod 110. An end cap 12 is provided at the upper end of the assembly frame 11, and a limiting slide 22 is fixedly connected to the lower middle part of the end cap 12. A sealing plate 112 is made, which is inserted into the second end slot 111. The depth of the second end slot 111 is equal to the height of the sealing plate 112. A side slot 13 is opened on one side of the upper end of the end cap 12, which is connected to the second end slot 111. A second limiting block 16 is provided at the lower end of the pressure block 21. The second limiting block 16 is fixedly connected to the assembly frame 11. A threaded hole 27 is opened in the middle of one side of the assembly cavity 17. A threaded rod 25 is threadedly connected inside the threaded hole 27. One end of the threaded rod 25 is fixedly connected to a limiting plate 24.

[0027] The overall effect of this embodiment is that, through the setting of the side groove 13, the end of the thermistor can be locked and restricted, ensuring stability during bending. Through the cooperation of the limiting plate 24 and the threaded rod 25, the movement range of the pressure block 21 can be adjusted by adjusting the position of the limiting plate 24 according to different actual needs, thereby adjusting the bending degree of the two pins, making it more applicable. Through the setting of the limiting slide 22, the pins are restricted to ensure the stability of pin bending. Through the setting of the roller 26, the friction effect is reduced by rotation, ensuring the stability of use.

[0028] The usage and working principle of this device are as follows: During the assembly of the thermistor, when bending the thermistor's leads, adjust the position of the limiting plate 24 according to the distance between the connection points at the assembly point. In use, insert the leads between the side slot 13 and the second end slot 111, and the leads enter the middle slot 28. Move the limiting slide 22 upward until it restricts the leads. Then press the pressure block 21 until it contacts the limiting plate 24. Then slide the limiting slide 22 downward to disengage the limiting slide 22 from the leads. Release the pressure block 21 and push it back to its original position using the spring 19. Lift the end cover 12 upward to disengage the limiting plate 112 from the second end slot 111, and the leads can be removed. In this way, the leads of the desensitizing resistor are complete. Then, assemble the desensitizing resistor with the bent leads.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
