Description

Technical Field

[0001] The utility model relates to the technical field of inductance skeletons, and specifically relates to a skeleton for installing an insulated integrated inductance. Background Art

[0002] In recent years, in order to achieve the goals of "carbon peak and carbon neutrality", the photovoltaic power generation industry has become one of the rapidly developing new energy industries. With the wide application of solar photovoltaic inverters, charging piles, UPSs, and energy storage devices, photovoltaic inductors have also developed rapidly, and the requirements for product structures and performances have become more and more diverse.

[0003] The inductance magnetic cores in the prior art need to be installed on an insulating skeleton and fixed to the chassis through the insulating skeleton; however, the existing insulating skeleton adopts a sheet metal base plus an insulating skeleton. The sheet metal part and the insulating skeleton are adhered by glue, and the sheet metal part is connected to the chassis by opening threaded holes. This combination method requires the use of metal and insulating materials, resulting in higher material costs and more processes for skeleton processing and assembly; in addition, since the existing insulating skeleton does not encapsulate the side parts of the magnetic core and the coil, making them exposed outside, when adjacent inductors are used side by side, a sufficient distance needs to be maintained to avoid mutual interference, which leads to an increase in space occupation. Summary of the Utility Model

[0004] The purpose of the utility model is to improve and innovate in view of the shortcomings and problems in the background art, and provide a skeleton for installing an insulated integrated inductance.

[0005] A skeleton for installing an insulated integrated inductance includes a first skeleton and a second skeleton. Both the first skeleton and the second skeleton include a horizontally formed part and a vertically formed part integrally formed. Bolt holes are provided on the horizontally formed part for fixing the skeleton to the chassis; positioning holes adapted to the middle column of the magnetic core of the inductance are provided on both the first skeleton and the second skeleton. The middle column of the magnetic core is used for winding the coil. At least one end of the vertically formed part extends along the central axis direction of the middle column of the magnetic core to form an extension part. The corresponding extension parts of the first skeleton and the second skeleton are closed together to separate the coils corresponding to adjacent inductors.

[0006] Further, a magnetic core upper cover is connected to the end of the middle column of the magnetic core. Support bumps are provided at the ends of the corresponding vertically formed parts of the first skeleton and the second skeleton far from the coil. The support bumps are arranged around the positioning hole, and the inner circle of the support bump is adapted to the magnetic core upper cover.

[0007] Further, both the first skeleton and the second skeleton correspond to one vertically formed part and two horizontally formed parts. The two horizontally formed parts are arranged on both sides of the lower surface of the vertically formed part.

[0008] A further solution is that the horizontal part is connected to the vertical part through a rib plate, and the rib plate extends along the height direction of the vertical part.

[0009] A further solution is that a protruding part extends from one end of the extending part away from the vertical part, and the protruding parts corresponding to the first skeleton and the second skeleton cooperate with each other.

[0010] A further solution is that a limiting groove is formed on the vertical part corresponding to the first skeleton, the coil is connected with a lead wire, and the limiting groove is used for the lead wire to pass through the vertical part.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: (1) Both the first skeleton and the second skeleton of the present utility model are composed of an integrally formed horizontal part and a vertical part, with low material cost and convenient processing and assembly; at least one end of the vertical parts corresponding to the first skeleton and the second skeleton extends along the central axis direction of the middle column of the magnetic core to form an extending part, and the corresponding extending parts are closed together. The closed extending parts can separate the magnetic cores and coils corresponding to adjacent inductors, avoiding mutual interference between adjacent inductors, so that adjacent inductors can be arranged side by side without the need to maintain a sufficient distance, avoiding an increase in space occupation;

[0012] (2) The horizontal part of the present utility model is connected to the vertical part through a rib plate, which plays a supporting role and prevents the skeleton from deforming;

[0013] (3) Support bumps are provided at one end of the vertical parts corresponding to the first skeleton and the second skeleton away from the coil, the support bumps are arranged around the positioning hole, and the inner circle of the support bumps is adapted to the magnetic core upper cover, which is convenient for limiting and supporting the magnetic core upper cover.

Detailed implementation manners

[0019] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the following provides a detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific implementation manners and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] Please refer to Figures 1 - 3 , the present utility model provides a skeleton for installing an insulated integrated inductor, including a first skeleton 1 and a second skeleton 2. Both the first skeleton 1 and the second skeleton 2 include an integrally formed horizontal portion 12 and a vertical portion 13. The number of the horizontal portions 12 is set to two, and the two horizontal portions 12 are arranged on both sides of the lower surface of the vertical portion 13. Since the horizontal portion 12 and the vertical portion 13 are integrally formed, it is not necessary to bond the two together with glue. Compared with bonding a sheet metal and an insulating material together to obtain an insulating skeleton, the insulating skeleton of the present application is convenient for processing and assembly, and moreover, the skeleton of the present application does not use a metal material, so the material cost is lower. Bolt holes 7 are formed in the horizontal portion 12 for mounting and fixing the insulating skeleton on the chassis.

[0023] The first skeleton 1 and the second skeleton 2 are both provided with positioning holes 10 adapted to the middle post 4 of the magnetic core of the inductor. The positioning holes 10 play a role in positioning the middle post 4 of the magnetic core. The middle post 4 of the magnetic core is used for winding the coil 5, and the end of the coil 5 is connected with a lead wire 6. In this embodiment, one end of the vertical portion 13 extends along the central axis direction of the middle post 4 of the magnetic core to form an extension portion 14. The corresponding extension portions 14 of the first skeleton 1 and the second skeleton 2 are closed together, which can separate the coils 5 corresponding to adjacent inductors and avoid interference between adjacent inductors. Therefore, when adjacent inductors are used side by side, it is not necessary to maintain a sufficient distance, avoiding an increase in space occupation.

[0024] Specifically, a protruding portion 15 protrudes from the end of the extension portion 14 away from the vertical portion 13. The corresponding protruding portions 15 of the first skeleton 1 and the second skeleton 2 cooperate with each other to achieve complete encapsulation of the side of the coil 5.

[0025] The end of the middle post 4 of the magnetic core is connected with a magnetic core upper cover 3. Support bumps 11 are provided at the ends of the corresponding vertical portions 13 of the first skeleton 1 and the second skeleton 2 away from the coil 5. The support bumps 11 are arranged around the positioning holes 10, and the inner circle of the support bumps 11 is adapted to the magnetic core upper cover 3. The support bumps 11 play a role in limiting and supporting the magnetic core upper cover 3.

[0026] The horizontal portion 12 is connected to the vertical portion 13 through a rib plate 8. The rib plate 8 extends along the height direction of the vertical portion 13. The rib plate 8 plays a supporting role to prevent the skeleton from deforming.

[0027] A limiting groove 9 is provided on the vertical portion 13 corresponding to the first skeleton 1. The limiting groove 9 is used for the lead wire 6 to pass through the vertical portion 13. The limiting groove 9 plays a role in positioning the lead wire 6 and can also prevent the installation height of the lead wire 6 from exceeding the vertical portion 13.

[0028] The working principle of the present utility model: During specific use, one end of the magnetic middle post 4 is bonded to one of the magnetic core upper covers 3 through glue. Then, the middle post 4 of the magnetic core passes through the second skeleton 2 through the positioning hole 10, the coil 5 is evenly wound around the middle post 4 of the magnetic core. Then, the end of the middle post 4 of the magnetic core with the wound coil 5 away from the second skeleton 2 passes through the first skeleton 1. Finally, another magnetic core upper cover 3 is bonded to the middle post 4 of the magnetic core through glue, thereby realizing the installation of the inductor on the insulating skeleton.
