UU type transformer

Technical Field

The utility model relates to an electronic components, concretely relates to transformer.

Background

The transformer and the inductor are separate devices, which makes it easy to select the electrical characteristics of the transformer and the inductor. The individual devices result in a larger footprint than the combined device. In some circuits, such as resonant tank circuits, it is desirable to use both a transformer and an inductor.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problems that: a UU transformer with an inductor is provided.

In order to solve the technical problem, the utility model provides a following technical scheme: a UU-shaped transformer comprises a UU-shaped iron core and a coil wound on the UU-shaped iron core, wherein a frame is arranged on the UU-shaped iron core and connected with an inductance plate, and an inductor is arranged on the inductance plate.

The UU-shaped iron core is formed by splicing two U-shaped iron cores, and the primary coil and the secondary coil are wound on the two U-shaped iron cores respectively.

The frame surrounds the UU shape iron core that has the coil, and the inductance plate is connected with the frame, and the inductance plate has the clearance with the UU shape iron core that has the coil around, installs the inductor on the inductance plate and faces away from the UU shape iron core.

Detailed Description

With reference to fig. 2 and 4, a UU transformer includes a UU core 10, a coil 20 wound around the UU core, a frame 30 disposed on the UU core, the frame being connected to an inductor block 40, and an inductor 50 mounted on the inductor block.

The frame 30 is fixedly connected to the UU-shaped iron core 10 around which the coil 20 is wound, and the inductor 50 is fixedly connected to the frame 30 through the inductor plate 40, thereby forming a stable transformer and inductor combination structure.

The frame 30 includes a pair of U-shaped connectors 31 which are cross-fitted to the UU-shaped iron core 10, and a connecting plate 32 which covers the surface of the coil 20 and is provided with insertion holes 320 which are fitted to the ends of the pair of U-shaped connectors. A coil is wound on each U-shaped connecting piece, a pair of U-shaped connecting pieces 31 are spliced to form the UU-shaped iron core 10, and the UU-shaped iron core is of a closed structure. The pair of U-shaped connecting members 31 are fitted to the pair of coils in a one-to-one manner, and each U-shaped connecting member covers a surface of the corresponding coil to form an enclosure for the corresponding coil, that is, the pair of U-shaped connecting members are cross-fitted to the UU-shaped iron core 10.

The sockets 320 on the connecting plate 32 mate with the ends of a pair of U-shaped connectors, which correspond to a pair of U-shaped connectors to lock the UU core 10 to the connecting plate 32.

An L-shaped extension 321 is arranged at one corner of the connecting plate 32, one end of the L-shaped extension is connected with one corner of the inductance plate 40, and the inductance plate is located beside the UU-shaped iron core 10 and has a certain gap with the frame 30. The inductor 50 is disposed adjacent to the transformer, which saves the overall space occupied by the combined structure.

The frame 30 further comprises a closed loop 33 enclosing a pair of U-shaped connectors 31 and said L-shaped extensions 321 facilitating the stability of the frame and the connection of the frame to the UU-shaped core 10 around which the coil 20 is wound.

The inductor slab 40 is provided with a plurality of U-shaped clips 41 which secure the toroidal inductor 50 to the inductor slab. The U-shaped clamping pieces are uniformly distributed along the circumferential direction of the inductor. The inductance plate block 40 is provided with a plurality of clamping interfaces 401, the end parts of the U-shaped clamping pieces 41 are clamped in the clamping interfaces, the U-shaped clamping pieces are fixedly connected with the inductance plate block 40, and further the inductor is fixedly connected with the inductance plate block 40.
