Description

Technical Field

[0001] This utility model relates to the field of inductor technology, and in particular to a stacked inductor. Background Technology

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, which only impedes changes in current. When no current is flowing through the inductor, it will try to impede the current from flowing through it when the circuit is closed; when current is flowing through the inductor, it will try to maintain the current when the circuit is open.

[0003] In the prior art, Chinese patent CN219123080U proposes a stacked miniature inductor. The inductor adopts a stacked structure, which avoids the traditional coil winding structure and effectively reduces the size of the inductor, which is conducive to the miniaturization of inductors. However, in practical applications, there are still problems such as the complex manufacturing process of stacked inductors and the inability to repair them after damage, resulting in the high cost of using stacked inductors. Therefore, we disclose a stacked inductor. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a stacked inductor to solve the problem of high cost of using stacked inductors.

[0005] To achieve the above objectives, this utility model provides a multilayer inductor, comprising a dielectric substrate, a multilayer coil fixedly connected to one end of the dielectric substrate, a connecting post fixedly connected to one end of the multilayer coil, dielectric shells sleeved on both sides of the dielectric substrate, a plurality of dielectric substrates and multilayer coils sleeved inside the dielectric shells, the plurality of multilayer coils being fixedly connected to each other by connecting posts, a hole being formed in the middle of the dielectric substrate, the hole being movably sleeved with the connecting post, two connecting posts located at both ends of the dielectric shells penetrating to the outside of the dielectric shells and respectively fixedly connected to a first electrode end and a second motor end, the two ends of the dielectric shells being movably sleeved with the first electrode end and the second motor end, the two dielectric shells being symmetrically distributed about the transverse central axis of the dielectric substrate, the first electrode end and the second motor end being symmetrically distributed about the longitudinal central axis of the dielectric substrate, and the first electrode end and the second motor end not being in contact.

[0006] Preferably, a plurality of dielectric partitions are fixedly connected to the inner side of the dielectric shell. The dielectric partitions are located on one side of the multilayer coil and are attached to the side edge of the multilayer coil. The height of the dielectric partitions is equal to the height of the multilayer coil.

[0007] Preferably, both the dielectric substrate and the stacked coil are enclosed within two dielectric shells.

[0008] Preferably, the two connecting posts extending to the outside of the medium shell are located on the upper and lower sides of both ends of the medium shell, respectively.

[0009] Preferably, a first connecting plate is fixedly connected to both sides of the first electrode end, and a second connecting plate is fixedly connected to both sides of the second motor end. Both the first and second connecting plates are L-shaped plates, with the first connecting plate being an inverted L-shaped plate. The first and second connecting plates are adapted to each other. A first limiting groove is provided on one side of both the first and second connecting plates, and a second limiting groove is provided on the other side of both the first and second connecting plates. The first limiting groove on the first connecting plate and the second limiting groove on the second connecting plate are located on the same side and form a connected arrow groove. A limiting rod is movably engaged in the arrow groove. A pull block is fixedly connected to one end of the limiting rod extending out of the second limiting groove. One side of the pull block is in contact with the medium shell. The pull block and the limiting rod form a T-shape.

[0010] Preferably, the limiting rod includes a V-shaped plate and a straight plate, the V-shaped plate and the straight plate are fixedly connected, the straight plate extends out of the limiting rod and is fixedly connected to the pull block, and the V-shaped plate is engaged in the arrow groove formed by the first limiting groove and the limiting rod.

[0011] Preferably, the dielectric substrate, the dielectric shell, the dielectric partition, the first connecting plate, and the second connecting plate are all made of insulating material, and the limiting rod and the pull block are all made of plastic.

[0012] The beneficial effects of this utility model are as follows: By restricting the positions of several dielectric substrates and stacked coils through the dielectric shell, and connecting the stacked coils to the first electrode and the second motor end through the connecting post, the first electrode and the second motor end restrict the position of the dielectric shell, thereby making the limiting protection effect of the two dielectric shells on the dielectric substrate better. After the dielectric substrates and stacked coils are stacked and connected, the position of the stacked dielectric substrates and stacked coils is restricted by the dielectric shell. Then, the first electrode and the second motor end are sleeved on the outer wall of the dielectric shell to complete the fabrication of the stacked inductor. This reduces the complexity of the fabrication process of the stacked inductor and allows the stacked inductor to be disassembled and inspected after damage. The damaged parts can be replaced and the inductor can continue to be used, saving the cost of using the stacked inductor.

[0013] The first connecting plate is fixed in position by the first electrode end, and the second connecting plate is fixed in position by the second motor end. This allows the first and second connecting plates to move only along the dielectric shell. Once the limiting rod enters the arrow groove formed by the first and second limiting grooves along the second limiting groove, it cannot move back without the limiting rod being damaged. This restricts the position of the first and second connecting plates after connection, preventing them from sliding along the dielectric shell. This, in turn, restricts the relative position of the first electrode end and the second motor end, thus fixing the first electrode end... The second motor end restricts the position of the medium shell. When it is necessary to open the medium shell, pull the pull block, which moves the limit rod. This causes one end of the limit rod, which is located in the arrow groove, to disconnect from the arrow groove, while the other end is pulled out of the second limit groove by the pull block. Then, the relative position of the first connecting plate and the second connecting plate is restricted and disconnected. After that, the first electrode end, the second motor end, and the medium shell can be removed for inspection. After the inspection is completed, when installing, a new limit rod is installed to fix the position of the first connecting plate and the second connecting plate, so that the position of the first connecting plate and the second connecting plate is stable and easy to disconnect after they are connected.

[0023] like Figures 1-4As shown, a multilayer inductor includes a dielectric substrate 1, with a multilayer coil 2 fixedly connected to one end of the dielectric substrate 1, and a connecting post 3 fixedly connected to one end of the multilayer coil 2. Dielectric shells 4 are fitted onto both sides of the dielectric substrate 1, and several dielectric substrates 1 and multilayer coils 2 are fitted inside the dielectric shells 4. The multilayer coils 2 are fixedly connected to each other via the connecting posts 3. A hole is formed in the middle of the dielectric substrate 1, and the hole is movably fitted with the connecting post 3. Two connecting posts 3 located at both ends of the dielectric shells 4 extend to the outside of the dielectric shells 4 and are respectively fixedly connected to a first electrode 6 and a second motor end 7. The two ends of the dielectric shells 4 are movably fitted with the first electrode 6 and the second motor end 7, respectively. The two dielectric shells 4 are symmetrically distributed about the transverse central axis of the dielectric substrate 1. The first electrode 6 and... The second motor end 7 is symmetrically distributed around the longitudinal central axis of the dielectric substrate 1. The first electrode end 6 and the second motor end 7 are not attached. Several dielectric partitions 5 are fixedly connected to the inner side of the dielectric shell 4. The dielectric partitions 5 are located on one side of the multilayer coil 2 and are attached to the side of the multilayer coil 2. The height of the dielectric partitions 5 is equal to the height of the multilayer coil 2. The dielectric substrate 1 and the multilayer coil 2 are both wrapped inside the two dielectric shells 4. Two connecting posts 3 that penetrate to the outside of the dielectric shell 4 are located on the upper and lower sides of both ends of the dielectric shell 4, respectively. In use, the multilayer coil 2 is fixedly connected to one end of the dielectric substrate 1, and the connecting post 3 is fixedly connected to one end of the multilayer coil 2. The dielectric shells 4 are sleeved on both sides of the dielectric substrate 1, and several dielectric substrates 1 and multilayer coils 2 are sleeved inside the dielectric shells 4. Several stacked coils 2 are fixedly connected by connecting posts 3. A hole is provided in the middle of the dielectric substrate 1, and the hole is movably sleeved with the connecting post 3, so that the dielectric substrate 1 fixes the position of the stacked coils 2. Several stacked coils 2 are connected by connecting posts 3, and the dielectric shell 4 restricts the position of several dielectric substrates 1 and stacked coils 2. Two connecting posts 3 located at both ends of the dielectric shell 4 penetrate to the outside of the dielectric shell 4 and are respectively fixedly connected to a first electrode 6 and a second motor end 7. The two ends of the dielectric shell 4 are movably sleeved with the first electrode 6 and the second motor end 7, so that the stacked coils 2 are connected to the first electrode 6 and the second motor end 7 through the connecting posts 3. The first electrode 6 and the second motor end 7 restrict the position of the dielectric shell 4, thereby making the two dielectric shells... 4 provides better positioning protection for the dielectric substrate 1. Two dielectric shells 4 are symmetrically distributed around the transverse central axis of the dielectric substrate 1, while the first electrode 6 and the second motor end 7 are symmetrically distributed around the longitudinal central axis of the dielectric substrate 1. The first electrode 6 and the second motor end 7 are not in contact, allowing the dielectric substrate 1 and the stacked coil 2 to be stacked and connected, with the dielectric shells 4 restricting their position. Then, the first electrode 6 and the second motor end 7 are fitted onto the outer wall of the dielectric shells 4, completing the fabrication of the stacked inductor. This reduces the complexity of the stacked inductor manufacturing process and allows for disassembly and inspection if the stacked inductor is damaged. Damaged components can be replaced for continued use, saving on the operating costs of stacked inductors.Several dielectric partitions 5 are fixedly connected to the inside of the dielectric housing 4. The dielectric partitions 5 are located on one side of the multilayer coil 2 and are attached to the side edge of the multilayer coil 2. The height of the dielectric partitions 5 is equal to the height of the multilayer coil 2. Both the dielectric substrate 1 and the multilayer coil 2 are enclosed within the two dielectric housings 4, allowing the dielectric partitions 5 to fill the gap between the dielectric substrate 1 and the multilayer coil 2. This makes the relative position of the dielectric substrate 1 and the multilayer coil 2 more stable after being enclosed within the dielectric housing 4, ensuring the inductor's performance. Two connecting posts 3, extending through to the outside of the dielectric housing 4, are located on the upper and lower sides of both ends of the dielectric housing 4, respectively, allowing the first electrode 6 and the second electrode 7, which are sleeved at both ends of the dielectric housing 4, to function normally.

[0024] As a preferred embodiment of this example, Figure 2 and Figure 3As shown, a first connecting plate 8 is fixedly connected to both sides of the first electrode end 6, and a second connecting plate 9 is fixedly connected to both sides of the second motor end 7. Both the first connecting plate 8 and the second connecting plate 9 are L-shaped plates, with the first connecting plate 8 being an inverted L-shaped plate. The first connecting plate 8 and the second connecting plate 9 are adapted to each other. A first limiting groove 10 is provided on one side of both the first connecting plate 8 and the second connecting plate 9, and a second limiting groove 11 is provided on the other side of both the first connecting plate 8 and the second connecting plate 9. The first limiting groove 10 on the first connecting plate 8 and the second limiting groove 11 on the second connecting plate 9 are located on the same side and form a connected arrow groove. A limiting rod 12 is movably engaged in the arrow groove, and a pull block 1 is fixedly connected to one end of the limiting rod 12 that extends out of the second limiting groove 11. 3. One side of the pull block 13 is attached to the dielectric shell 4. The pull block 13 and the limiting rod 12 form a T-shape. The limiting rod 12 includes a V-shaped plate and a straight plate, which are fixedly connected. The straight plate extends out of the limiting rod 12 and is fixedly connected to the pull block 13. The V-shaped plate is engaged in the arrow groove formed by the first limiting groove 10 and the limiting rod 12. The dielectric substrate 1, dielectric shell 4, dielectric partition 5, first connecting plate 8 and second connecting plate 9 are all made of insulating material. The limiting rod 12 and the pull block 13 are both made of plastic. The first connecting plate 8 is fixedly connected to both sides of the first electrode end 6, and the second connecting plate 9 is fixedly connected to both sides of the second motor end 7. The first connecting plate 8 and the second connecting plate 9 are both L-shaped plates. The first connecting plate 8 is an inverted L-shaped plate. The first motor end 6 is adapted to the second connecting plate 9, so that the first motor end 6 fixes the position of the first connecting plate 8, and the second motor end 7 fixes the position of the second connecting plate 9. The first connecting plate 8 and the second connecting plate 9 cover the connection seam between the two dielectric shells 4, reducing the possibility of dust entering the dielectric shell 4. The first connecting plate 8 and the second connecting plate 9 can only move along the dielectric shell 4. A first limiting groove 10 is provided on one side of each of the first connecting plate 8 and the second connecting plate 9, and a second limiting groove 11 is provided on the other side of each. The first limiting groove 10 on the first connecting plate 8 and the second limiting groove 11 on the second connecting plate 9 are located on the same side and form a connected arrow groove. A limiting mechanism is activated within the arrow groove. A lever 12, with a pull block 13 fixedly connected to one end extending from the second limiting groove 11, prevents the limiting lever 12 from moving back without being damaged after entering the arrow groove formed by the first limiting groove 10 and the second limiting groove 11 along the second limiting groove 11. This restricts the position of the first connecting plate 8 and the second connecting plate 9 after they are connected, preventing them from sliding along the medium shell 4. Consequently, it restricts the relative position of the first electrode end 6 and the second motor end 7, thus limiting the position of the medium shell 4. When it is necessary to open the medium shell 4, pulling the pull block 13 causes the limiting lever 12 to move.This causes one end of the limiting rod 12 to disconnect from the arrow groove, while the other end is pulled out of the second limiting groove 11 by the pull block 13. Then, the relative positions of the first connecting plate 8 and the second connecting plate 9 are restricted and disconnected. Afterwards, the first electrode 6, the second motor end 7, and the dielectric shell 4 can be removed for inspection. Upon reinstallation after inspection, a new limiting rod 12 is installed to fix the positions of the first connecting plate 8 and the second connecting plate 9. The pull block 13 is attached to the dielectric shell 4 on one side, forming a T-shape with the limiting rod 12, thus allowing the pull block 13 to... 3. The design facilitates pulling, preventing damage to the pull block 13 when compressed. The limiting rod 12, comprising a V-shaped plate and a straight plate, is fixedly connected. The straight plate extends out and is fixedly connected to the limiting rod 12 and pull block 13. The V-shaped plate engages with the arrow groove formed by the first limiting groove 10 and the limiting rod 12, providing good unidirectional limiting effect. The dielectric substrate 1, dielectric shell 4, dielectric partition 5, first connecting plate 8, and second connecting plate 9 are all made of insulating material, while the limiting rod 12 and pull block 13 are made of plastic, ensuring normal operation of the inductor.
