Description

Technical Field

[0001] The utility model relates to the technical field of thermistors, and particularly relates to a thermistor element. Background Art

[0002] A thermistor is a sensor resistor whose resistance value changes with temperature. It is divided into a positive temperature coefficient thermistor and a negative temperature coefficient thermistor according to different temperature coefficients. The resistance value of a positive temperature coefficient thermistor increases with the increase of temperature, and the resistance value of a negative temperature coefficient thermistor decreases with the increase of temperature. They both belong to semiconductor devices.

[0003] The patent document with the publication number of CN220306057U discloses a PTC thermistor with a leg protection structure. Through the protection mechanism, it is convenient to protect the legs on the PTC thermistor body, avoid the bending or breaking of the connection part between the legs and the PTC thermistor body, resulting in overall damage and affecting its normal use; through the support mechanism, it is convenient to support and fix the PTC thermistor body, avoid its inclination and damage due to force, and at the same time, by rotating the driving cylinder, it is convenient to adjust the overall height of the PTC thermistor body, improving its practicability.

[0004] Although the above-mentioned PTC thermistor with a leg protection structure can solve the corresponding technical problems, its protection mechanism can only carry out protection operations on two legs with a certain distance. However, the distances between the two legs of different types of thermistors are also different, which makes it difficult for the protection mechanism to carry out protection operations on thermistors of different sizes, thus reducing the applicable range of the protection mechanism. Therefore, we propose a thermistor element. Summary of the Utility Model

One side of the first protective shell 41 is rotatably connected to the second protective shell 42 through a rotating shaft, and a connecting piece is arranged between the other side of the first protective shell 41 and the second protective shell 42; The distance adjusting assembly 5 includes a bidirectional screw 51 horizontally movably arranged at the bottom of the inner cavity of the bearing assembly 2. Both sides of the surface of the bidirectional screw 51 are threadedly sleeved with a screw sleeve 52. The screw sleeve 52 is arranged in one-to-one correspondence with the second protective shell 42, and a connecting plate 53 is fixedly connected between the screw sleeve 52 and the corresponding second protective shell 42.

[0027] Among them, the main body assembly 1 includes a thermistor body 11. A lead 12 is respectively connected to the front and rear sides of the surface of the thermistor body 11. The first protective shell 41 and the second protective shell 42 are symmetrically arranged front and rear and form a receiving cavity for placing the lead 12.

[0028] Among them, the bearing assembly 2 includes a protective cover 21 sleeved on the surface of the thermistor body 11. The front side of the protective cover 21 is provided in an open shape for the taking and placing of the main body assembly 1. A rubber seat 22 is fixedly connected to the top of the inner wall surface of the protective cover 21. The top of the thermistor body 11 contacts the bottom of the rubber seat 22. The fixing assembly 3 is arranged at the bottom of the protective cover 21 and is arranged in correspondence with the rubber seat 22.

[0029] Among them, a slot hole 23 is opened on both sides of the bottom of the protective cover 21. The first protective shell 41 is arranged in one-to-one correspondence with the slot hole 23. The outer surface of the first protective shell 41 is slidably connected to the inner wall surface of the corresponding slot hole 23. The tops of the first protective shell 41 and the second protective shell 42 both penetrate through the corresponding slot hole 23 into the inner cavity of the protective cover 21. The slot hole 23 can provide a moving space for the protection assembly 4 to ensure that the protection assembly 4 can move horizontally normally.

[0030] Among them, the fixing component 3 includes a baffle 31 integrally formed at the bottom of the shield 21. The baffle 31 is located between two slot holes 23. A stud 32 is vertically threaded through the bottom of the shield 21. The top of the stud 32 is rotatably connected to a clamping plate 33 through a bearing. A rubber pad 34 in contact with the bottom surface of the bottom of the thermistor body 11 is fixedly connected to the top of the clamping plate 33. By rotating the stud 32, under the action of the thread, the clamping plate 33 and the rubber pad 34 can be driven to move up and down, and thus can cooperate with the rubber seat 22 to clamp and fix thermistor bodies 11 of different models. One side of the clamping plate 33 is slidably connected to the baffle 31, and the baffle 31 can be used to limit the clamping plate 33 to prevent the clamping plate 33 from rotating synchronously with the stud 32, so that the clamping plate 33 can move up and down stably.

[0031] Among them, the connecting member includes a convex block 43 fixedly connected to one side of the second housing 42. One side of the convex block 43 facing the first housing 41 is rotatably connected to a positioning block 44 through a damping rotating shaft. A positioning frame 45 adapted to the positioning block 44 is fixedly connected to one side of the first housing 41. When the first housing 41 is flipped to be in a closed state with the second housing 42, the positioning block 44 can penetrate to one side of the positioning frame 45, and then by rotating the positioning block 44, the positioning frame 45 can be positioned, so that the first housing 41 and the second housing 42 can be stably maintained in the closed state to realize the protection operation of the lead 12.

[0032] Among them, one end of the bidirectional screw 51 is rotatably connected to the inner wall surface of the shield 21 through a bearing. The other end of the bidirectional screw 51 movably penetrates to the outside of the shield 21. The bottoms of the screw sleeve 52 and the connecting plate 53 are both slidably connected to the bottom of the inner cavity of the shield 21, which can play a limiting role on the screw sleeve 52 and the connecting plate 53 to prevent the screw sleeve 52 and the connecting plate 53 from rotating synchronously with the bidirectional screw 51, so that the screw sleeve 52 and the connecting plate 53 can move left and right stably. To ensure the stability of the rotation of the bidirectional screw 51, the surface of the bidirectional screw 51 is rotatably connected to the penetrating part of the shield 21 through a bearing. The bidirectional screw 51 is located behind the clamping plate 33, which can effectively avoid the phenomenon that the bidirectional screw 51 blocks the up and down movement of the clamping plate 33.

[0033] Among them, a knob 6 is fixedly connected to one end of each of the bidirectional screw 51 and the stud 32, which is convenient for rotating the bidirectional screw 51 and the stud 32.

[0034] The working principle of the present utility model is as follows: By rotating the knob 6 on the bidirectional screw rod 51, the knob 6 drives the bidirectional screw rod 51 to rotate. Under the action of the thread, the bidirectional screw rod 51 drives the two screw sleeves 52 on its surface to move synchronously towards or away from each other. The screw sleeve 52 drives the connecting plate 53 to move, and the connecting plate 53 drives the corresponding protective component 4 to move synchronously in the inner cavity of the slot hole 23, so as to be able to adjust the two protective components 4 to an appropriate position according to the distance between the two leads 12. After the adjustment is completed, the thermistor body 11 is placed in the inner cavity of the protective cover 21, and the lead 12 is placed in the corresponding accommodating cavity. The top of the thermistor body 11 contacts the rubber seat 22. Rotate the knob 6 on the stud 32, so that the knob 6 drives the stud 32 to rotate. Under the action of the thread, the stud 32 drives the clamping plate 33 and the rubber pad 34 to move upward until the rubber pad 34 contacts the bottom of the thermistor body 11, so as to be able to fix the thermistor body 11 in the inner cavity of the protective cover 21. After the fixation is completed, flip the first protective shell 41 so that the first protective shell 41 and the corresponding second protective shell 42 are in a closed state. At the same time, the positioning block 44 passes through one side of the corresponding positioning frame 45. Rotate the positioning block 44 so that the positioning block 44 and the through hole on the positioning frame 45 are arranged in an interleaved manner, and the positioning frame 45 can be positioned, so that the first protective shell 41 and the second protective shell 42 are stably maintained in a closed state, so as to be able to shield and protect the lead 12 through the protective component 4, effectively avoiding the phenomenon that the lead 12 is bent or broken under force and affecting its normal use.
