Description

Technical Field

[0001] This utility model relates to the field of inductor technology, and specifically to an inductor. Background Technology

[0002] An inductor consists of a coil, magnetic core, housing, terminals, regulator, shield, temperature sensor, and control circuitry. The housing is the external protective structure of the inductor, typically made of plastic or metal, used to protect the internal components from physical damage and environmental influences. A search of existing technology (publication number: CN221281847U) reveals "an inductor with easily adjustable inductance strength, comprising a housing, an inductor body fixedly disposed inside the housing, a fixing plate fixedly disposed on the surface of the inductor body, an insulating plate fixedly disposed at one end of the fixing plate, a connecting strip fixedly disposed on the surface of the inductor body, and an insulating protective shell fixedly disposed on the surface of the fixing plate. This utility model, through the arrangement of the fixing plate, insulating plate, connecting strip, and insulating protective shell, allows for the following: when the inductor is turned on, the overflowing current is blocked by the insulating plate; the upper and lower insulating plates are connected by the connecting strip; and the fixing plate fixes the insulating protective shell to the inductor body. The insulating protective shell prevents dust from entering, thus protecting the inductor body, reducing the risk of short circuits during use, and avoiding danger to personnel."

[0003] Although existing inductors achieve insulation protection, they still have some shortcomings: the heat dissipation components involved in the above-mentioned inductors are installed inside the housing, close to the inductor body, but the fan blades of the heat dissipation components are driven by a motor, and the long-term operation of the motor will also generate heat, resulting in poor heat dissipation effect; secondly, although the housing provides protection, the inductor body needs to be connected to an external power supply to work, so the housing included in the above-mentioned inductor structure is inconvenient for wiring operations and protection of the wiring terminals. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, an inductor is provided to solve the problems of poor heat dissipation and inconvenience in wiring and protection based on the sealed housing in the existing technology.

[0005] To achieve the above objectives, an inductor is provided, comprising: an inductor housing and a cover plate. An inductor body is disposed inside the inductor housing. A first heat dissipation hole and a second heat dissipation hole are respectively provided on the side wall and top end of the inductor housing. A first heat dissipation device is disposed outside the first heat dissipation hole, and a second heat dissipation device is disposed outside the second heat dissipation hole. The cover plate is hinged to the outer wall of the inductor housing, and a wiring hole is provided on the inner side of the cover plate. A terminal block is provided inside the wiring hole. A movable plate is connected inside the terminal block, and a threaded rod is screwed onto the upper end of the movable plate.

[0006] Furthermore, the second heat dissipation device has the same structure as the first heat dissipation device, and the second heat dissipation device includes a connecting cover connected to the outside of the second heat dissipation hole.

[0007] Furthermore, the second heat dissipation device also includes a fan cylinder connected to the outside of the connecting cover, and a mounting plate is connected to the outside of the fan cylinder, and a dustproof net is connected to the outer end of the fan cylinder, while a connecting column is connected to the outer wall of the mounting plate.

[0008] Furthermore, the inductor body is connected to the terminal block via a wire passing through the movable plate and the terminal block, and a second fixing plate and a first fixing plate are respectively provided at the upper and lower ends of the inner side of the movable plate.

[0009] Furthermore, the threaded rod rotates through the shell wall of the inductor housing, and the threaded rod is screwed through the movable plate, and the inner end of the threaded rod is rotatably connected to the second fixed plate.

[0010] Furthermore, a guide rod is slidably connected inside the lower end of the movable plate, and the two ends of the guide rod are respectively fixed to the inner wall of the first fixed plate and the inductor housing.

[0011] Furthermore, the cover plate has a wire hole inside, and the wire hole is adapted to the horizontal height of the terminal block, and the volume of the cover plate is larger than the opening area of ​​the wire hole.

[0012] Furthermore, two pins are slidably connected to the outer side of the cover plate, and a guide plate is fixed to the outer wall of the cover plate. The pins are slidably inserted into the inside of the guide plate. At the same time, a pinch block is connected to the opposite end of the pins, and the outer end of the pins is inserted into the positioning sleeve welded to the outer wall of the inductor housing when the cover plate is closed.

[0013] Furthermore, the outer wall of the pin is connected to a limiting plate, and the limiting plate is slidably connected between the guide plates. A spring is sleeved on the outer side of the pin, and the spring is located between the limiting plate and the guide plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. During heat dissipation, two sets of heat dissipation devices are used. When in use, the fan inside the fan barrel of one set of heat dissipation devices is in the exhaust state, while the fan inside the fan barrel of the other set of heat dissipation devices is in the blowing state. This creates a faster airflow inside the inductor housing. Since the fan is located outside the inductor housing, it avoids the heat generated during operation being inside the inductor housing, thereby improving the heat dissipation effect.

[0016] 2. When wiring, first hold the pinch block to move the pin closer, causing it to disengage from the positioning sleeve. Then, open the cover plate to expose the wiring hole. Next, turn the threaded rod with a screwdriver to drive the moving plate outward through the threaded connection, which in turn moves the terminal block outward until the terminal is outside the wiring hole. Then, pass the power wire and ground wire that need to be connected through the wiring hole on the cover plate and connect them to the terminal. Then, reverse the threaded rod to reset the terminal block to the inside of the wiring hole. Finally, flip the cover plate over to cover the outside of the wiring hole, allowing the pin to engage with the positioning sleeve. This method facilitates wiring and protects the wiring terminals after wiring. Attached Figure Description

[0023] Reference Figures 1 to 5 As shown, this utility model provides an inductor, including: an inductor housing 1 and a cover plate 2. An inductor body 12 is provided inside the inductor housing 1. A first heat dissipation hole 11 and a second heat dissipation hole 15 are respectively opened on the side wall and the top end of the inductor housing 1. A first heat dissipation device 13 is provided on the outside of the first heat dissipation hole 11, and a second heat dissipation device 14 is provided on the outside of the second heat dissipation hole 15. The cover plate 2 is hinged to the outer wall of the inductor housing 1. A wiring hole 17 is opened on the inner side of the cover plate 2. A wiring terminal 123 is provided on the inner side of the wiring hole 17. A wiring board 122 is connected to the inner side of the wiring terminal 123. A movable plate 121 is connected to the inner side of the wiring board 122. A threaded rod 127 is screwed to the upper end of the movable plate 121.

[0024] In this embodiment, the inductor housing 1, the internal structure, and the cover plate 2 constitute the main structure of the inductor involved in this application. The inductor body 12 includes a magnetic core and a copper coil wound on its surface.

[0025] like Figure 1 and Figure 5 In the first heat dissipation device 13, the second heat dissipation device 14 has the same structure. The second heat dissipation device 14 includes a connecting cover 145 connected to the outside of the second heat dissipation hole 15. The second heat dissipation device 14 also includes a fan cylinder 144 connected to the outside of the connecting cover 145. A mounting plate 142 is connected to the outside of the fan cylinder 144, and a dustproof net 143 is connected to the outer end of the fan cylinder 144. Meanwhile, a connecting post 141 is connected to the outer wall of the mounting plate 142.

[0026] Specifically, the dustproof net 143 and the outer end of the fan cylinder 144 are detachably connected for easy disassembly and cleaning. At the same time, the fan cylinder 144 is equipped with a fan, and the fan blades rotate inside the cylinder. Furthermore, the connecting post 141 is fixed to the outer wall of the inductor housing 1.

[0027] like Figure 1 , Figure 2 and Figure 4 In the inductor body 12, the inductor body 12 is connected to the terminal block 123 through the moving plate 121 and the terminal block 122 via wires. The upper and lower ends of the moving plate 121 are respectively provided with a second fixing plate 126 and a first fixing plate 125. The threaded rod 127 rotates through the shell wall of the inductor housing 1 and is screwed through the moving plate 121. The inner end of the threaded rod 127 is rotatably connected to the second fixing plate 126. The lower end of the moving plate 121 is slidably connected to a guide rod 124, and the two ends of the guide rod 124 are respectively fixed to the first fixing plate 125 and the inner wall of the inductor housing 1.

[0028] Specifically, the volume of the terminal block 123 is smaller than that of the wiring hole 17, which facilitates the terminal block 123 to move outward, and the volume of the moving plate 121 is larger than that of the wiring hole 17, which limits the movement of the terminal block 123.

[0029] As a preferred embodiment, the threaded rod 127 and guide rod 124 make it easy to directionally remove the terminal 123 from the outside of the inductor housing 1 using a screwdriver.

[0030] like Figure 1 and Figure 3 In the cover plate 2, a wire hole 21 is provided inside, and the wire hole 21 is adapted to the horizontal height of the terminal 123. The volume of the cover plate 2 is larger than the opening area of ​​the terminal 17. Two pins 22 are slidably connected to the outside of the cover plate 2. At the same time, a guide plate 26 is fixed to the outer wall of the cover plate 2, and the pins 22 are slidably inserted into the guide plate 26. At the same time, a pinch block 25 is connected to the opposite end of the pins 22. When the cover plate 2 is closed, the outer end of the pins 22 is correspondingly inserted into the positioning sleeve 16 welded to the outer wall of the inductor housing 1. A limit plate 23 is connected to the outer wall of the pins 22, and the limit plate 23 is slidably connected between the guide plates 26. A spring 24 is sleeved on the outside of the pins 22. The spring 24 is located between the limit plate 23 and the guide plate 26.

[0031] Specifically, the inner wall of the wire hole 21 is provided with a rubber ring to achieve elastic clamping and anti-scratching effect for the power cord.

[0032] Specifically, two guide plates 26 are slidably connected to the outer side of the same pin 22, which ensures the linear movement of the pin 22. One end of the spring 24 contacts the guide plate 26 near the end of the pinch block 25, so that when the pinch block 25 is released, the pin 22 can be easily released outward to insert into the positioning sleeve 16.

[0033] In use, two sets of heat dissipation devices are employed. One set of devices, including a fan barrel, operates in exhaust mode, while the other set operates in blowing mode. This creates rapid airflow inside the inductor housing, and the fans, positioned outside the housing, prevent heat from accumulating inside, thus improving heat dissipation. For wiring, first, hold the lever to move the pin closer, disengaging it from the positioning sleeve. Then, open the cover to expose the wiring holes. Next, turn the screwdriver to drive the moving plate outwards, moving the terminal block until the terminals are outside the wiring holes. Pass the power and ground wires through the wiring holes on the cover and connect them to the terminals. Then, reverse the screwdriver to return the terminal block to the inside of the wiring holes. Finally, flip the cover to cover the wiring holes, allowing the pin to engage with the positioning sleeve. This method facilitates wiring and protects the terminals after wiring.

[0034] The inductor of this invention can effectively solve the problems of poor heat dissipation and inconvenience in wiring and protection when the inductor has a sealed housing. It improves the heat dissipation effect and facilitates wiring and protection based on existing inductor technology.
