Description

Technical Field

[0001] The present invention relates to the technical field of electronic components, and in particular to a resonant inductor and transformer integrated device and an assembling method thereof. Background Art

[0002] With the rapid development of electronic technology, electronic equipment has increasingly higher requirements for component integration, efficiency and space utilization. In traditional electronic systems, transformers and inductors, as key electromagnetic components, are often designed as independent components, which are used to realize functions such as voltage conversion, current conversion and impedance matching, as well as to store and release magnetic field energy to hinder current changes. However, this split design has many limitations, such as large space occupation, complex assembly, high cost, and to a certain extent, it limits the miniaturization and lightweight of the system. How to integrate inductors and transformers is an important trend in the development of electronic component technology, and is an effective solution to meet the needs of modern electronic equipment for high integration, high efficiency and high space utilization.

[0003] When some existing integrated inductor and transformer devices are in use, the coil windings thereon are alternately wound around the iron core. This tightly interwoven structure makes it extremely complicated to remove or replace any winding, which is not conducive to reducing maintenance costs and time.

[0004] For example, the patent number CN216648033U discloses a transformer and inductor integrated device. The transformer and inductor integrated device of the patent adopts a transformer and an inductor integrated design, including a first iron core, a second iron core, a first winding and a second winding. The second winding is wound on the second iron core, and then the second iron core is placed on the first iron core, and then the first winding is wound. The first winding can be used as an inductor winding and also as the primary winding of the transformer. The second winding is only used as the secondary winding of the transformer. It can realize the function of both the transformer and the inductor, and the functions of the transformer and the inductor do not affect each other. The overall structure is more compact and occupies less space.

[0005] Although the above-mentioned transformer and inductor integrated device adopts an integrated design of transformer and inductor, making the overall structure very compact and conducive to saving space, since the first winding and the second winding are alternately wound on the iron core, this tightly interwoven structure makes it extremely complicated to remove or replace any winding, increasing maintenance costs and time.

[0006] Therefore, it is necessary to invent a resonant inductor and transformer integrated device and an assembly method thereof to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a resonant inductor and transformer integrated device and an assembly method thereof to solve the problems in the above-mentioned technology.

[0009] A gap is left between the No. 1 frameless coil winding and the No. 1 iron core to facilitate the subsequent insertion of the No. 2 iron core and the No. 2 frameless coil winding, thereby realizing the integrated integration of the resonant inductor and the transformer.

[0010] Preferably, a No. 1 positioning groove is provided at one end of the No. 2 iron core, and the No. 1 positioning block is snap-connected with the No. 1 positioning groove.

[0012] Preferably, a No. 2 positioning groove is provided at one end of the No. 1 iron core, and the No. 2 positioning block is snap-connected with the No. 2 positioning groove.

[0013] The No. 2 positioning block is engaged with the No. 2 positioning groove on the No. 1 iron core, which further enhances the stability of the entire device, prevents the iron core from shifting during operation, and ensures the stability of electrical performance.

[0015] The design of the No. 1 through hole enables the No. 1 lead end of the No. 1 frameless coil winding to be easily led out, which is convenient for connection with an external circuit, thereby improving the practicability and flexibility of the device.

[0016] Preferably, a second through hole is opened on the surface of the second loading plate, and the second frameless coil winding is provided with a second lead wire end, and the second lead wire end is arranged through the second through hole.

[0018] Preferably, a protective shell is provided between the first loading plate and the second loading plate, and heat dissipation holes are provided on the surface of the protective shell.

[0019] The heat dissipation holes opened on the surface of the protective shell can effectively dissipate the heat generated inside the device, prevent performance degradation or damage due to excessive temperature, and improve the working stability and service life of the device.

At the same time, this design is also easy to disassemble and maintain.

[0022] In addition, the present invention also provides an assembly method of a resonant inductor and transformer integrated device, comprising the following steps:

[0023] Step 1: First, sleeve the No. 1 frameless coil winding on the outside of the No. 1 iron core, and make one side of the inner wall of the No. 1 frameless coil winding fit with the No. 1 iron core, and leave a certain gap between the other side of the inner wall of the No. 1 frameless coil winding and the No. 1 iron core, and the No. 1 lead end of the No. 1 frameless coil winding passes through the No. 1 through hole on the surface of the No. 1 loading plate and extends to the outside, so as to facilitate line connection;

[0024] Step 2: Then, sleeve the second frameless coil winding on the outside of the second iron core, and make the inner wall of the second frameless coil winding fit closely with the second iron core. The second lead end of the second frameless coil winding passes through the second through hole on the surface of the second loading plate and extends to the outside, so as to facilitate line connection;

[0025] Step 3, then place the protective shell between the No. 1 loading plate and the No. 2 loading plate, and then push the No. 1 loading plate and the No. 2 loading plate closer to each other, so that the No. 2 iron core and the No. 2 frameless coil winding are inserted into the gap between the No. 1 frameless coil winding and the No. 1 iron core, the No. 1 frameless coil, the No. 2 iron core and the No. 2 frameless coil winding form an integrated device through the wrapping of the No. 1 frameless coil;

[0026] Step 4: During the assembly process, the No. 1 positioning groove at one end of the No. 2 iron core is engaged with the No. 1 positioning block on the surface of the No. 1 loading plate, and the No. 2 positioning groove at one end of the No. 1 iron core is engaged with the No. 2 positioning block on the surface of the No. 2 loading plate, so as to realize the positioning of the No. 1 iron core and the No. 2 iron core;

[0027] Step 5. After the assembly is completed, the frame-shaped card strips at both ends of the protective shell are respectively connected with the frame-shaped card slots on the surface of the No. 1 loading board and the No. 2 loading board. After the No. 1 loading board, the No. 2 loading board and the protective shell are spliced ​​together to form a complete shell, which plays a role in protecting the internal electrical components.

[0028] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0029] 1. The frameless coil winding No. 1 and the frameless coil winding No. 2 are independently sleeved on the outside of the No. 1 iron core and the No. 2 iron core, and the two are plugged in through the gap between the frameless coil winding No. 1 and the No. 1 iron core, thereby avoiding interweaving and interference between the coil windings. The coil windings that are not intertwined are easy to be repaired or replaced separately, which is conducive to reducing maintenance costs and time;

[0030] 2. By setting the No. 1 positioning groove and the No. 2 positioning groove on the No. 1 iron core and the No. 2 iron core respectively, and engaging with the No. 1 positioning block on the No. 1 loading plate and the No. 2 positioning block on the No. 2 loading plate, precise positioning between the iron core and the loading plate is achieved.
