Technical Field
[0001] This utility model relates to the field of connector terminal technology, and in particular to inductor connector terminals with a dustproof structure. Background Technology
[0002] In modern electronic devices, inductors are key components in circuits, and the stability and reliability of their performance are of paramount importance. Connecting terminals are electrical components used to connect wires or other electrical components so that the circuit can function properly.
[0003] During the use of connector terminals, it is usually necessary to manually operate components such as movable end plates. Furthermore, the connection method of movable end plates is usually set as a flipping mechanism, which affects the sealing effect. In addition, traditional designs lack effective dustproof sealing and mechanisms to prevent wires from falling off, resulting in unstable connections and affecting the stability and reliability of inductor connectors.
[0004] Therefore, to address the aforementioned issues of difficulty in achieving dustproof sealing and preventing wire detachment, an inductor connection terminal with a dustproof structure can be designed. During use, the lower end of the movable plate and the upper end of the fixed plate are tightly pressed together, and the sealing ring is pushed to slide to the connection between the plug and the plug cylinder. This achieves dustproof sealing of the connection gap and prevents wire detachment, ensuring the stability and reliability of the inductor connection. Utility Model Content

This not only affects the stability of the connecting wire, but may also lead to the deterioration of the inductor performance and even cause equipment failure.
[0006] The technical solution of this utility model is as follows: an inductor connection terminal with a dustproof structure, including a wire terminal, a fixed clamping plate, a movable clamping plate, an inner cavity, a plug-in cylinder, a connecting wire, a plug-in connector, a plug-in ring, a fixed ring, a sealing ring, an adjusting gear, a sliding toothed plate, an adjusting toothed plate, and a pressing rod.

Then, insert the connector of one end of the connecting wire into the insertion cylinder. Subsequently, after the lower end of the movable locking plate and the upper end of the fixed locking plate are tightly pressed together to form a closed state, the inner cavity is sealed, thus achieving a dustproof sealing effect and preventing the wire end from falling off. During this process, the inner wall of the insertion ring is pressed against one end of the pressing rod. The other end can push the sliding toothed plate to slide inward. Since the sliding toothed plate meshes with one side of the adjusting gear, the sliding toothed plate can drive the adjusting gear to rotate. Since the other side of the adjusting gear meshes with the adjusting toothed plate, the adjusting gear can drive the adjusting toothed plate to slide outward. This can push the sealing ring to slide to the connection between the plug and the plug sleeve, and can achieve dustproof sealing and prevent detachment of the connection gap. In summary, the inductor connection terminal achieves the functions of dustproof sealing and preventing the connection wire from falling off through the ingenious mechanical structure design, ensuring the stability and reliability of the inductor connection wire.

Next, press the lower end of the movable locking plate tightly against the upper end of the fixed locking plate to form a closed state, ensuring the inner cavity is sealed and achieving a dustproof seal. This also prevents the wire end from falling off. During this process, the inner wall of the connector ring presses against one end of the compression rod, while the other end of the compression rod... The end can push the sliding toothed plate to slide inward. Since the sliding toothed plate meshes with one side of the adjusting gear, the sliding toothed plate can drive the adjusting gear to rotate.

One side of the adjusting gear 11 meshes with the sliding toothed plate 12, and the other side of the adjusting gear 11 meshes with the adjusting toothed plate 13. The sealing ring 10 slides to the connection point between the connector 7 and the connector cylinder 5, thus achieving dustproof sealing and preventing detachment of the connection gap. A through-hole is formed on the side wall of the front fixed ring 9. A sliding hole 15 is provided, and the extrusion rod 14 is slidably connected to the inside of the front fixing ring 9 through the sliding hole 15. The inner wall of the insertion ring 8 is in contact with one end of the extrusion rod 14.

[0025] Please see Figure 3 and Figure 5A through slot 18 is provided at the top front end of the wire terminal 1. A toggle plate 19 is fixedly installed on the lower side wall of the movable locking plate 3. Two sets of sliding grooves 20 are provided on both sides of the front end of the wire terminal 1. A sliding rod 21 is fixedly installed inside the sliding groove 20. A slider 22 is installed on the side wall of the sliding rod 21. The slider 22 is slidably connected to the sliding rod 21. An adjusting spring 23 is installed inside the sliding groove 20. The upper end of the adjusting spring 23 is fixedly connected to the inner wall of the sliding groove 20, and the lower end of the adjusting spring 23 is fixedly connected to the inner wall of the slider 22. Both sides of the movable locking plate 3 are fixedly connected to the inner walls of the two sets of sliders 22. Pulling the toggle plate 19 upward will cause the movable locking plate 3 to move upward, thereby opening the inner cavity 4. During this process, the movable locking plate 3 can drive the sliders 22 on both sides to move upward along the sliding rod 21. At this time, the adjusting springs 23 on both sides are compressed and deformed, storing force for the subsequent reset movement. The two sets of fixed rings 9 are fixedly connected. Multiple sets of guide rods 24 are fixedly provided. Guide seats 25 are provided on the side walls of the guide rods 24. The guide seats 25 are slidably connected to the guide rods 24.

One end of the return spring 26 is fixedly connected to the inner wall of the rear fixed ring 9. The other end of the return spring 26 is fixedly connected to the side wall of the guide seat 25.

A sliding seat 28 is provided on the side wall of the sliding rod 27. The sliding seat 28 is slidably connected to the sliding rod 27. The side wall of the sliding tooth plate 12 is fixedly connected to the side wall of the sliding seat 28. The sliding tooth plate 12 can drive the sliding seat 28 to slide smoothly inward along the sliding rod 27.
[0026] During use, when connecting the wire 6 to the terminal 1, firstly, pulling the actuating plate 19 upwards will cause the movable locking plate 3 to move upwards, thereby opening the inner cavity 4 and providing space for the insertion of the wire 6. During this process, the movable locking plate 3 will cause the two sliding blocks 22 to move upwards along the sliding rod 21. At this time, the adjusting springs 23 on both sides will deform under pressure, storing force for the subsequent reset movement.
[0027] Then, insert the connector 7 at one end of the connecting wire 6 into the inside of the connector cylinder 5. Next, release the actuating plate 19. Under the elastic action of the adjusting springs 23 on both sides, the sliders 22 on both sides can move downwards along the slide rod 21, thereby causing the movable locking plate 3 to move downwards along the slide groove 20. When the lower end of the movable locking plate 3 comes into close contact with the upper end of the fixed locking plate 2, a closed state is formed, ensuring the sealing of the inner cavity 4, thus achieving a dustproof sealing effect and preventing the connecting wire 6 from falling off.
[0028] During this process, the inner wall of the insertion ring 8 is pressed against one end of the extrusion rod 14, while the other end of the extrusion rod 14 pushes the sliding toothed plate 12 to slide inward. At this time, the sliding toothed plate 12 can drive the sliding seat 28 to slide smoothly inward along the sliding rod 27. Since the sliding toothed plate 12 meshes with one side of the adjusting gear 11, the sliding toothed plate 12 can drive the adjusting gear 11 to rotate on the adjusting shaft 17. Since the other side of the adjusting gear 11 meshes with the adjusting toothed plate 13, the adjusting gear 11 can drive the adjusting toothed plate 13 to slide outward. One end of the adjusting toothed plate 13 can push the upper guide seat 25 to slide smoothly outward along the guide rod 24, thereby pushing the sealing ring 10 to slide to the connection between the insertion joint 7 and the insertion cylinder 5, and achieving the effect of dustproof sealing and preventing detachment of the connection gap.
[0029] In summary, the inductor connection terminal, through its ingenious mechanical structure design, achieves dustproof sealing and prevents the connecting wire 6 from falling off, thus ensuring the stability and reliability of the inductor connection.
[0030] Through the above steps, when the connecting wire 6 is plugged into the wire terminal 1 during use, firstly, the movable locking plate 3 is pulled upwards to move upwards, thereby opening the inner cavity 4 and providing space for the insertion of the connecting wire 6. Then, the plug 7 at one end of the connecting wire 6 is inserted into the inside of the plug-in cylinder 5. Subsequently, the lower end of the movable locking plate 3 is tightly pressed against the upper end of the fixed locking plate 2 to form a closed state, which ensures the sealing of the inner cavity 4, thereby achieving a dustproof sealing effect and preventing the wire end from falling off. During this process, the inner wall of the plug ring 8 is pressed against one end of the pressing rod 14, and the other end of the pressing rod 14... The end can push the sliding toothed plate 12 to slide inward. Since the sliding toothed plate 12 meshes with one side of the adjusting gear 11, the sliding toothed plate 12 can drive the adjusting gear 11 to rotate. Since the other side of the adjusting gear 11 meshes with the adjusting toothed plate 13, the adjusting gear 11 can drive the adjusting toothed plate 13 to slide outward. This can push the sealing ring 10 to slide to the connection between the plug 7 and the plug sleeve 5, and can achieve dustproof sealing and prevent detachment of the connection gap. In summary, the inductor connection terminal achieves the functions of dustproof sealing and preventing the connection wire 6 from falling off through the ingenious mechanical structure design, ensuring the stability and reliability of the inductor connection.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
