When the inductor is inserted, the plug-in head is deformed, and the end of the extrusion pin connected to the pull wire will move upward. The pull wire will move upward with the elastic kit to expose the wiring pin, so that the wiring pin can be easily inserted into the clip on the circuit. The operation is quick, time-saving and labor-saving. However, the inductor will generate heat when working, and the inductor cannot achieve the heat dissipation effect. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the inductor generates heat during operation and cannot achieve the heat dissipation effect, and to propose a plug-in inductor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plug-in inductor, comprising: a frame and pins constituting the inductor; a temperature sensor is installed at the top of the inner cavity of the frame, and the temperature sensor is used to sense the temperature of the inductor during operation; the upper and lower ends of the frame are both provided with heat dissipation holes, and a baffle is rotatably connected to the interior of the heat dissipation hole, and an air bag is provided on the inner side of the baffle for dust prevention.

[0006] As a further solution of the present invention, a miniature first electric push rod is installed inside the skeleton, a support block is fixed inside the skeleton, a rack is slidably connected inside the support block, a gear is rotatably connected inside the skeleton, and one end of the rack is rotatably connected to the baffle.

[0007] As a further solution of the present invention, a hollow warehouse is provided inside the skeleton, there is air inside the hollow warehouse, a piston is slidably connected inside the hollow warehouse, a second electric push rod is installed inside the skeleton, and the output end of the second electric push rod extends to the interior of the hollow warehouse and is fixedly connected to the piston.

[0008] As a further solution of the present invention, the number of the support blocks and the racks is two, and one support block cooperates with one rack.

[0009] As a further solution of the present invention, the gear is located inside the two racks, and the gear is engaged with the two racks at the same time, and the output end of the first electric push rod is fixedly connected to one of the racks.

[0010] As a further solution of the present invention, the temperature sensor is electrically connected to a controller in the circuit, and the first electric push rod and the second electric push rod are electrically connected to the temperature sensor and to the controller.

[0013] 1. The controller controls the output end of the second electric push rod to extend and drive the piston to move in the hollow chamber, and then compress the air in the hollow chamber. The compressed air then enters the interior of the airbag through the exhaust pipe.

[0014] 2. The electric heater generates heat when it is working. The temperature sensor senses the temperature of the electric heater.

Then the controller controls the output end of the first electric push rod to extend and descend with the rack, and then the other first electric push rod is moved by the rotation of the gear. The two first electric push rods move in opposite directions. Since one end of the rack is rotatably connected to the baffle, the rack moves to drive the baffle to rotate and then open the heat dissipation holes. The heat is discharged from the heat dissipation holes, which is conducive to the heat dissipation of the inductor. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The following describes an embodiment of the present invention based on the overall structure of the present invention.

[0022] A plug-in inductor includes: a skeleton 1 and pins 2 constituting the inductor. A temperature sensor 3 is installed on the top of the inner cavity of the skeleton 1. The temperature sensor 3 is used to sense the temperature of the inductor during operation.

[0023] Furthermore, a miniature first electric push rod 7 is installed inside the skeleton 1, a support block 8 is fixed inside the skeleton 1, a rack 9 is slidably connected inside the support block 8, a gear 10 is rotatably connected inside the skeleton 1, one end of the rack 9 is rotatably connected to the baffle 5, and the temperature sensor 3 is electrically connected to the controller in the circuit.

[0024] Next, the first electric push rod 7 and the second electric push rod 15 are electrically connected to the temperature sensor 3 and the controller. The gear 10 is located inside the two racks 9, and the gear 10 is engaged with the two racks 9 at the same time. The output end of the first electric push rod 7 is fixedly connected to one of the racks 9. The number of the support blocks 8 and the racks 9 is two, and one support block 8 is matched with one rack 9.

[0025] Specifically, the electric heater generates heat when it is working, and the temperature sensor 3 senses the temperature of the electric heater. When the sensed temperature reaches a dangerous threshold, the temperature sensor 3 transmits a signal to the controller, and then the controller controls the output end of the first electric push rod 7 to extend and descend with the rack 9, and then the other first electric push rod 7 is moved by the rotation of the gear 10, and the two first electric push rods 7 move in opposite directions. Since one end of the rack 9 is rotatably connected to the baffle 5, the rack 9 drives the baffle 5 to rotate when it moves and then opens the heat dissipation hole 4. The heat is discharged from the heat dissipation hole 4, which is conducive to the heat dissipation of the inductor.

[0026] Furthermore, heat dissipation holes 4 are provided at both the upper and lower ends of the skeleton 1, and a baffle 5 is rotatably connected to the inside of the heat dissipation hole 4. An air bag 6 for dust prevention is provided on the inner side of the baffle 5. A hollow warehouse 12 is provided inside the skeleton 1, and there is air inside the hollow warehouse 12. A piston 13 is slidably connected to the inside of the hollow warehouse 12. A second electric push rod 15 is installed inside the skeleton 1, and the output end of the second electric push rod 15 extends to the inside of the hollow warehouse 12 and is fixedly connected to the piston 13. The hollow warehouse 12 is connected to an exhaust pipe, and the tail end of the exhaust pipe passes through the baffle 5 and is connected to the air bag 6.

[0027] It can be concluded that the controller controls the output end of the second electric push rod 15 to extend and drive the piston 13 to move in the hollow chamber 12, and then compresses the air in the hollow chamber 12. The compressed air then enters the interior of the airbag 6 through the exhaust pipe. After the airbag 6 is filled with air, it expands rapidly to seal the connection between the heat dissipation hole 4 and the baffle 5, preventing dust in the circuit from entering the interior of the skeleton 1.

[0028] Working principle: When current passes through a wire, a concentric magnetic field is generated with the wire as the center; when alternating current occurs, the self-current of the inductor changes, and the induced electromotive force is caused by the change of its own magnetic flux. The change of self-inductance current caused by blockage is a change in the direction of the current. When the alternating current increases, the self-inductance current is opposite to the alternating current. When the alternating current decreases, the self-inductance current is the same as the alternating current, which then hinders communication. The above is the principle of the inductor. In the non-heat dissipation state, the controller controls the output end of the second electric push rod 15 to extend and drive the piston 13 to move in the hollow chamber 12, and then compresses the air in the hollow chamber 12. The compressed air then enters the interior of the airbag 6 through the exhaust pipe. After the airbag 6 is filled with air Rapid expansion seals the connection between the heat dissipation hole 4 and the baffle 5 to prevent dust in the circuit from entering the interior of the skeleton 1. The electric heater generates heat when working, and the temperature sensor 3 senses the temperature of the electric heater. When the sensed temperature reaches the dangerous threshold, the temperature sensor 3 transmits a signal to the controller, and then the controller controls the output end of the first electric push rod 7 to extend and descend with the rack 9, and then the other first electric push rod 7 is moved by the rotation of the gear 10. The two first electric push rods 7 move in opposite directions. Since one end of the rack 9 is rotatably connected to the baffle 5, the rack 9 drives the baffle 5 to rotate when it moves and then opens the heat dissipation hole 4. The heat is discharged from the heat dissipation hole 4, which is conducive to the heat dissipation of the inductor.

[0029] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
