Description

Technical Field

[0001] The utility model relates to the technical field of mobile devices, in particular to a high-strength shock-absorbing low-voltage reactor. Background Art

[0002] A reactor is also called an inductor. When a conductor is energized, it will generate a magnetic field in a certain space it occupies. However, the inductance of a long straight conductor carrying current is small, and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid form, called an air-core reactor.

[0003] In the current market, reactors are indispensable components in power systems, and their stable and reliable performance is crucial to the operation of the entire system. However, as the use time increases, the iron core inside the reactor may be damaged, aged, or its performance degraded due to various reasons. These conditions not only affect the normal operation of the reactor, but may also pose potential safety hazards to the entire power system. Therefore, when these problems occur in the iron core of the reactor, it needs to be replaced in a timely manner. Utility Model Content

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0024] like Figure 1-4 As shown, the present application provides a high-strength shock-absorbing low-voltage reactor, including an upper iron yoke 1 and a lower iron yoke 2:

[0025] The iron core 3 is fixedly mounted between the upper iron yoke 1 and the lower iron yoke 2. A bottom plate 31 is fixedly mounted on the bottom of the iron core 3, and a slot 33 is provided on the surface of the bottom plate 31.

[0026] Specifically, such as Figure 2 As shown, a plurality of T-shaped slots 21 are provided on the surface of the lower iron yoke 2, and a T-shaped block 32 is fixedly mounted on the lower surface of the bottom plate 31, and the T-shaped block 32 is slidably connected to the inside of the T-shaped slot 21;

[0027] In this embodiment, the T-shaped slot 21 and the T-shaped block 32 are matched to each other, so that the core 3 can be more stable during disassembly and installation, and the position deviation of the core 3 can be avoided.

[0028] The limiting mechanism 4 is located between the upper iron yoke 1 and the lower iron yoke 2 and is used to limit the iron core 3. The limiting mechanism 4 includes a bidirectional screw rod 41, which is rotatably connected between the upper iron yoke 1 and the lower iron yoke 2. A clamping block 44 is threadedly connected to the surface of the bidirectional screw rod 41, and the clamping block 44 is movably inserted into the inner part of the clamping slot 33;

[0029] Specifically, such as Figure 3As shown, a symmetrical thread groove 411 is opened on the surface of the bidirectional screw rod 41, and the two thread grooves 411 are in opposite directions. The clamping block 44 is threadedly connected to the surface of the thread groove 411 below the bidirectional screw rod 41, and the moving block 43 is threadedly connected to the surface of the thread groove 411 above the bidirectional screw rod 41;

[0030] In this embodiment, when the bidirectional screw rod 41 rotates, the clamping block 44 moves down to the inside of the clamping slot 33 to limit the iron core 3, and the movable block 43 moves up to fit the fixed block 11 to complete the connection between the external wire and the wire plate 34.

[0031] Specifically, such as Figure 4 As shown, a fixed block 11 is fixedly mounted on the lower surface of the upper iron yoke 1, and a placement groove 111 is provided on the surface of the fixed block 11. The surface of the movable block 43 is movably fitted with the lower surface of the fixed block 11, and an arcuate groove 431 is provided on the surface of the movable block 43. The arcuate groove 431 and the placement groove 111 are in the same vertical plane. A wire plate 34 is fixedly connected to the surface of the iron core 3, and the wire plate 34 is movably placed inside the placement groove 111.

[0032] In this embodiment, the wire plate 34 is placed inside the placement groove 111, and the external wire is placed inside the arc groove 431. When the movable block 43 is attached to the fixed block 11, the wire plate 34 is connected to the external wire.

[0033] Specifically, such as Figure 2 As shown, a handle 42 is fixedly mounted on one end of the bidirectional screw rod 41, and the handle 42 is rotatably connected to the surface of the upper iron yoke 1. The other end of the bidirectional screw rod 41 is rotatably connected to the surface of the lower iron yoke 2. The handle 42 and the upper iron yoke 1 are both provided with a socket 421, and a pin 45 is movably inserted into the socket 421.

[0034] In this embodiment, the rotation of the bidirectional screw rod 41 is achieved by rotating the handle 42 . After the bidirectional screw rod 41 has completed its rotation, the cooperation between the latch 45 and the socket 421 prevents the bidirectional screw rod 41 from rotating.

[0035] Specifically, such as Figure 2 As shown, a guide rod 12 is fixedly installed between the upper iron yoke 1 and the lower iron yoke 2, and the clamping block 44 and the moving block 43 are both slidably connected to the surface of the guide rod 12;

[0036] In this embodiment, the guide rod 12 makes the clamping block 44 and the moving block 43 more stable when moving and prevents the clamping block 44 and the moving block 43 from rotating around the bidirectional screw rod 41 as the center of the circle.

[0037] The specific solution is as follows: first, remove the pin 45 on the surface of the handle 42 from the inside of the socket 421, turn the handle 42 clockwise, and the bidirectional screw rod 41 rotates. At this time, the block 44 is moved out from the inside of the slot 33 on the surface of the bottom plate 31, and the limit on the iron core 3 is cancelled. At the same time, the moving block 43 is away from the surface of the fixed block 11, and the connection between the external wire and the wire plate 34 is disconnected. The old iron core 3 is taken out along the inside of the T-slot 21. After replacing the new iron core 3, the wire plate 34 is replaced in the placement slot 111 on the surface of the fixed block 11, and the external wire is placed in the arc groove 431 on the surface of the moving block 43. Turn the handle 42 counterclockwise, and the block 44 is moved back to the inside of the slot 33 to limit the iron core 3. The moving block 43 moves up to connect the external wire to the wire plate 34 again.

[0038] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative; within the spirit of the present invention, the technical features of the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
