Problems solved by technology

However, due to the feature that this metal sheet 80 cannot be bent during assembly (once it is bent and deformed, it is not easy to bend it by hand to restore it to its original shape), it is horizontal (the main core of the iron core extends laterally) ) structure is open, there is no vertical (the main core of the iron core is for vertical extension) structure products, which seriously affects the diversity and competitiveness of products

Embodiment 1

[0030] Such as Figure 5 As shown, a transformer of the present invention includes a wire frame body 1, a wire frame cover 2, a metal block 3 and an iron core 4, wherein the center of the wire frame body 1 is provided with a first through hole 11, and the first through hole 11 A wire groove 12 is formed on the outer peripheral side, and a plurality of outwardly protruding outer protrusions 121 are provided at corners of the outer surface of the wire groove 12 . The wire frame body 1 is provided with a terminal block 13 and 14 at both ends of the first through hole 11, wherein the terminal block 13 is provided with a plurality of primary-side conductive posts 131, and the terminal block 14 is provided with a plurality of spare conductive posts 143 And two gaps 141,142. The wire stand body 1 is provided with at least two opposite first engaging portions 122 (such as hook portions) on the edge of the first through hole 11 .

[0031] A second through hole 21 corresponding to the f...

Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that in this embodiment, the side parts of the upper and lower iron cores of the present invention are respectively provided with a slot and a buckle that can be engaged with each other. The core is connected, easy to disassemble and assemble, and does not need the clips in Embodiment 1.

[0038] Other structures are the same as in Embodiment 1.

Abstract

The present invention provides a transformer, comprising: a wire frame body, a first through hole is provided in the center of the wire frame body, wire slots are formed on the outer peripheral side of the first through hole, and wire slots are formed at both ends of the first through hole. There are two opposite wiring seats; wire frame cover, the center of the wire frame cover is provided with a second through hole corresponding to the first through hole; a metal block, the center of the metal block is provided with a hole parallel to the first through hole The third through hole of the hole, and the outer peripheral side of the wire groove is covered by the third through hole, and one end of the metal block extends two flat folded parts parallel to each other in the direction perpendicular to the third through hole; two opposite An iron core, the center of the iron core is provided with a main core part inserted into the first through hole, and the outer side of the main core part is provided with two opposite side parts, and the main core part and the side parts are formed between the main core part and the side part. Two side openings are provided at the two ends of the main core in the accommodation groove for accommodating the main body of the wire frame in the extending direction of the accommodation groove, and the wire base protrudes outward through the side openings.

Description

technical field [0001] The invention relates to the technical field of transformer manufacturing, and more particularly, to a transformer that is easy to manufacture and assemble. Background technique [0002] In the prior art, common transformers are coil-type transformers, most of which use two wires (enameled wires) to be wound on the same iron core respectively to form a primary side coil connected to the power supply terminal and a secondary side coil connected to the load terminal. . The induced voltage generated between the primary side coil and the secondary side coil depends on the coil turn ratio of the primary side coil and the secondary side coil. When the above common coil-type transformer needs to change its output voltage, at least the number of turns and the number of turns of its secondary side coil must be changed, so it must be designed and manufactured according to the specific specifications of each transformer. As a result, it will inevitably cause in...
