Description

Technical Field

[0001] The utility model belongs to the technical field of PFC inductors, and in particular relates to a PFC inductor which is easy to assemble. Background Art

[0002] The full name of PFC is "Power Factor Correction", which means "power factor correction". Power factor refers to the relationship between effective power and total power consumption, that is, the ratio of effective power to total power consumption. The larger the power factor value, the higher the power utilization rate. PFC inductors are inductors used to form PFC circuits, which are used to improve power factors, and are used in new energy vehicle batteries. They are used with other large transformers to increase speed. The Chinese patent publication number CN217740323U discloses a PFC inductor, which includes an outer frame, a base member and a coil assembly. The outer frame is provided with a mounting hole for accommodating the base member. The base member includes a skeleton and pins, and the pins are fixedly connected to the skeleton. The coil assembly is sleeved on the skeleton. The length of the base member along the opening direction of the mounting hole is greater than the length of the skeleton, and the end of the base member away from the pins is fixedly connected to the outer frame. This application allows the outer frame to be less affected by the position of other components on the circuit board when the PFC inductor is installed on the circuit board, which can facilitate the installation of the PFC inductor.

[0003] The problem with the prior art is that the outer frame of the PFC inductor is only provided with one mounting hole for accommodating the basic component, and the surface of the outer frame is smooth. When two inductors need to be assembled and used together, auxiliary tools are needed to connect the two outer frames together, which makes assembly and disassembly more troublesome. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a PFC inductor that is easy to assemble and has the advantages of convenient assembly and disassembly. It solves the problem that the existing PFC inductor has only one mounting hole for accommodating basic components on the outer frame, and the surface of the outer frame is smooth. When two inductors need to be assembled and used together, auxiliary tools are needed to connect the two outer frame parts together, and the assembly and disassembly are relatively troublesome.

[0005] The utility model is implemented as follows: a PFC inductor that is easy to assemble includes a first connecting block and a second connecting block, wherein two of the first connecting block and the second connecting block are provided and are fixedly installed at the upper and lower ends of two skeletons respectively, a coil is provided outside the skeleton, a connecting mechanism is provided on the side where the first connecting block and the second connecting block are close to each other at the upper end, and the first connecting block and the second connecting block at the lower end are installed in a mounting plate, and pins are fixedly installed at the bottom of the mounting plate.

[0006] As a preferred embodiment of the utility model, fixing strips and protective covers are provided on the bottom of the first connecting block and the second connecting block, connecting pieces are integrated at two diagonal parts of the mounting plate, screw sleeves are fixedly installed in the two connecting pieces, and a plurality of reinforcing ribs are integrated at the bottom of the mounting plate.

[0007] As a preferred embodiment of the present invention, two mounting grooves are formed on the upper surface of the mounting plate, and the first connecting block and the second connecting block at the lower end are fixedly installed in the two mounting grooves respectively.

[0008] As a preferred embodiment of the utility model, second slots are provided on both sides of the first connecting block and the second connecting block at the lower end, and spring sheets are fixedly connected to both side walls of the installation slot, and the spring sheets are correspondingly engaged with the second slots.

[0009] As a preferred embodiment of the utility model, the connecting mechanism includes an insert block and two fixed blocks, the insert block is fixedly connected to one side of the second connecting block at the upper end, and the two fixed blocks are fixedly connected to one side of the first connecting block at the upper end.

[0010] As a preferred embodiment of the utility model, the insert block is inserted between two fixed blocks, a connecting sleeve is fixedly connected inside the insert block, and a partition is fixedly connected to the middle of the connecting sleeve.

[0011] As a preferred embodiment of the utility model, both sides of the partition are fixedly connected to limit rods, and springs are sleeved on the two limit rods. One end of the two springs are respectively fixedly connected to the upper and lower surfaces of the partition, and the other ends are respectively fixedly connected to two clamping blocks.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model connects the first connecting block and the second connecting block at the upper end through a connecting mechanism to achieve preliminary fixation between the two inductors. During assembly, the plug-in block is plugged between the two fixing blocks. During the plug-in process, the two clamping blocks located on both sides of the partition contact the two fixing blocks. The surfaces of the two clamping blocks are smooth, so that the two fixing blocks can slide relative to each other on the surfaces of the clamping blocks, so that the two clamping blocks compress the spring inward until the clamping block is pressed into the inside of the connecting sleeve. When the position of the clamping block corresponds to the first clamping groove, the spring drives the clamping block to move outward under the action of its own elastic force, so that the clamping block is clamped into the first clamping groove, thereby achieving connection between the first connecting block and the second connecting block, and at the same time achieving preliminary fixation between the two skeletons.

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5As shown, an embodiment of the utility model provides a PFC inductor that is easy to assemble, including a first connecting block 3 and a second connecting block 6.

[0026] In the present application, two mounting grooves 403 are provided on the mounting plate 4 to accommodate two inductors. The first connecting block 3 and the second connecting block 6 are provided at both upper and lower ends of the two skeletons 101, the first connecting block 3 and the second connecting block 6 at the upper ends of the two skeletons 101 are connected through the connecting mechanism 2, and then the first connecting block 3 and the second connecting block 6 at the lower ends of the two skeletons 101 are plugged into the mounting groove 403. This allows for quick assembly of the two PFC inductors, thereby reducing the time and workload required for the assembly process, thereby improving production efficiency and reducing costs. Second slots 303 are provided on both sides of the first connecting block 3 and the second connecting block 6 at the lower end, and mounting grooves 403 corresponding to the second slots 303 are provided on the side walls of the mounting grooves 403, so that the spring sheet 404 abuts against the second slots 303. This makes the inductor installation operation easier and faster, and also facilitates subsequent maintenance or repair. The connecting piece 401 and the screw sleeve 402 are provided diagonally on the mounting plate 4, so that the mounting plate 4 can be easily installed on the electrical device.

[0027] Furthermore, the connecting mechanism 2 includes an insert block 202 and two fixed blocks 201, the insert block 202 is fixedly connected to one side of the second connecting block 6 at the upper end, the two fixed blocks 201 are fixedly connected to one side of the first connecting block 3 at the upper end, the insert block 202 is inserted between the two fixed blocks 201, a connecting sleeve 204 is fixedly connected inside the insert block 202, a partition 205 is fixedly connected to the middle of the connecting sleeve 204, both sides of the partition 205 are fixedly connected with limit rods 206, and springs 207 are sleeved on the rod bodies of the two limit rods 206, one end of the two springs 207 is respectively fixedly connected to the upper surface and the lower surface of the partition 205, and the other end is respectively fixedly connected with two clamping blocks 208, a first clamping groove 203 is opened on the side close to the two fixed blocks 201, and a disassembly hole 209 is opened on one side of the two first clamping grooves 203, the two clamping blocks 208 are clamped with the inner wall of the first clamping groove 203, and the two clamping blocks 208 are slidably connected to the inner wall of the connecting sleeve 204.

[0028] In the present application, the connecting mechanism 2 is used to connect the upper first connecting block 3 and the second connecting block 6 to achieve preliminary fixation between the two inductors. During assembly, the plug-in block 202 is plugged between the two fixed blocks 201. During the plug-in process, the two clamping blocks 208 located on both sides of the partition 205 contact the two fixed blocks 201. The surfaces of the two clamping blocks 208 are smooth, which can enable the two fixed blocks 201 to slide relatively on the surfaces of the clamping blocks 208, so that the two clamping blocks 208 compress the spring 207 inward until the clamping block 208 is pressed into the inside of the connecting sleeve 204. When the position of the clamping block 208 corresponds to the first clamping groove 203, the spring 207 drives the clamping block 208 to move outward under the action of its own elastic force, so that the clamping block 208 is clamped into the first clamping groove 203, thereby achieving the connection between the first connecting block 3 and the second connecting block 6, and at the same time achieving preliminary fixation between the two skeletons 101.

[0029] During the specific setting, one end of the two limit rods 206 is slidably inserted into the interior of the block 208, which can limit the block 208. The block 208 is slidably connected to the inner wall of the connecting sleeve 204, which can guide the block 208. During disassembly, the block 202 can be pulled out from between the two fixed blocks 201 by inserting a rod tool into the disassembly hole 209 and pressing the block 208 into the connecting sleeve 204, thereby completing the disassembly. The above technical solution can improve the reliability and stability of the inductor assembly.

[0030] The working principle of this utility model:

[0031] During assembly, the plug-in block 202 is plugged between the two fixed blocks 201. During the plug-in process, the two clamping blocks 208 located on both sides of the partition 205 contact the two fixed blocks 201. The surfaces of the two clamping blocks 208 are smooth, so that the two fixed blocks 201 can slide relatively on the surfaces of the clamping blocks 208, so that the two clamping blocks 208 compress the spring 207 inward until the clamping block 208 is pressed into the inside of the connecting sleeve 204. When the position of the clamping block 208 corresponds to the first clamping groove 203, the spring 207 drives the clamping block 208 to move outward under the action of its own elastic force, so that the clamping block 208 is clamped into the first clamping groove 203, thereby realizing the connection between the first connecting block 3 and the second connecting block 6, and realizing the preliminary fixation between the two skeletons 101. Then, the first connecting block 3 and the second connecting block 6 at the lower end are installed into the two installation grooves 403, so that the spring piece 404 is clamped with the second clamping groove 303, and the assembly of the inductor is completed.

[0032] In summary, the PFC inductor which is easy to assemble connects the upper first connection block 3 and the second connection block 6 through the connection mechanism 2 to achieve the initial fixation between the two inductors. During assembly, the plug-in block 202 is plugged between the two fixing blocks 201. During the plug-in process, the two clamping blocks 208 located on both sides of the partition 205 contact the two fixing blocks 201. The surfaces of the two clamping blocks 208 are smooth, which enables the two fixing blocks 201 to slide relatively on the surfaces of the clamping blocks 208, so that the two clamping blocks 208 compress the spring 207 inwardly until the clamping block 208 is pressed into the inside of the connecting sleeve 204. When the position of the clamping block 208 corresponds to the first clamping groove 203, the spring 207 drives the clamping block 208 to move outward under the action of its own elastic force, so that the clamping block 208 is clamped into the first clamping groove 203, thereby achieving the connection between the first connection block 3 and the second connection block 6, and at the same time achieving the connection between the two skeletons 101. The two inductors can be initially fixed by opening two mounting grooves 403 on the mounting plate 4, and can accommodate two inductors. The first connecting block 3 and the second connecting block 6 are provided at the upper and lower ends of the two skeletons 101, and the first connecting block 3 and the second connecting block 6 at the upper ends of the two skeletons 101 are connected through the connecting mechanism 2, and then the first connecting block 3 and the second connecting block 6 at the lower ends of the two skeletons 101 are inserted into the mounting groove 403, so that the two PFC inductors can be quickly assembled to reduce the time and workload required for the assembly process, thereby improving production efficiency and reducing costs. The second slots 303 are opened on both sides of the first connecting block 3 and the second connecting block 6 at the lower end, and the mounting grooves 403 corresponding to the second slots 303 are opened on the side walls of the mounting grooves 403, so that the spring piece 404 abuts against the second slots 303, which can improve the inductor installation operation easier and faster, and also facilitate subsequent maintenance or repair.
