Abstract

The utility model relates to a new transformer skeleton, including the wire winding groove, the wire winding groove be one section 3mm wide, the degree of depth is about 5mm, the diameter is the I-shaped cylinder type rubber component about 25mm the rubber component about be provided with lower flange and last flange respectively as the fender board lower flange edge be provided with the terminal board on distribute and be provided with the pin of being connected with wire winding electricity. The utility model discloses simple structure, and the wire winding groove is shorter, and the diameter is great for the wire winding height can be thinner, and the space can let bigger magnetic core supporting greatly, reaches the purpose that highly increases transformer power simultaneously that reduces the transformer.

Description

Transformer framework

Technical Field

The utility model relates to a transformer field, especially a novel transformer skeleton.

Background

The transformer is an electric appliance which transfers electric energy or transmission signals from one circuit to another circuit by utilizing the principle of electromagnetic induction, and is mainly composed of an iron core, a coil and a transformer framework. The transformer Bobbin, also known as a transformer Bobbin, and collectively called "Bobbin", is a main structural component of the transformer, and mainly plays a role in insulation, winding, and assembly of a magnetic core in the transformer.

Chinese patent document CN 207781371U discloses a transformer bobbin, which includes: the device comprises an upper platform, a lower platform, a plurality of baffle structures and a plurality of connecting plates; a plurality of said baffle structures being disposed side-by-side between said upper platform and said lower platform; the baffle structures, the baffle structures adjacent to the upper platform and the baffle structures adjacent to the lower platform and the lower platform are connected through the connecting plates; the upper portion platform, lower part platform, a plurality of baffle structure and a plurality of the middle part of connecting plate all is provided with the center and is located same straight line and the same magnetic core hole of cross section size. The transformer framework can reduce the electric energy loss and the production cost. But the structure is complex and the power of the formed transformer is small.

Disclosure of Invention

The utility model discloses to present transformer skeleton structure complicated, and the transformer power who forms is little not enough, and is bulky, and the special design provides a high-power, ultra-thin transformer skeleton.

The utility model discloses a realize that the technical scheme that its technical purpose adopted is: a transformer framework comprises a winding post, wherein the winding post is an I-shaped thin pipe with a section of 3mm wide, a depth of 4-5mm and a diameter of 13-15 mm, a lower flange and an upper flange are respectively arranged above and below the thin pipe to serve as wire blocking plates, a wiring table is arranged on the edge of the lower flange, and pins electrically connected with a winding wire are distributed on the wiring table.

The utility model discloses simple structure, and the I shape cylinder is big and thin for the wrapping post intermediate space can let bigger magnetic core supporting greatly, reduces the purpose that highly increases transformer power simultaneously of transformer.

Further, in the transformer bobbin: and a wire groove is also arranged between the adjacent pins on the wiring platform.

Further, in the transformer bobbin: and a second wire groove is also arranged on one side of the edge of the lower flange opposite to the wiring platform.

Further, in the transformer bobbin: the thickness of the thin pipe is 0.7mm, the diameter of the thin pipe is 13.7mm, and the depth of the thin pipe is 4 mm.

The present invention will be described in more detail with reference to the accompanying drawings and examples.

Drawings

Fig. 1 is a transformer bobbin structure diagram according to embodiment 1 of the present invention.

Fig. 2 is a right side view of fig. 1.

Detailed Description

Embodiment 1, as shown in fig. 1 and fig. 2, this embodiment is a high-power transformer bobbin with an ultra-thin thickness, and mainly includes a winding post for winding, in this embodiment, the winding post is a small section of i-shaped thin tube 1, as shown in fig. 2, the length of the small section of thin tube 1 is 4mm, the thickness of the thin tube 1 is only 0.7mm, but the inner diameter of the thin tube 1 is 13.7mm, it can be seen that the winding post in this embodiment is a section of thin tube 1 with a larger inner diameter, and more magnetic cores can be placed in the thin tube, so that the power of the transformer is increased. Practically, the winding post is a section of cylinder with 3mm width, 5mm depth and 13-15 mm diameter.

As shown in fig. 1, an upper flange 3 and a lower flange 2 are respectively arranged above and below a thin pipe 1 to serve as line blocking plates, a wiring table 4 is arranged at the edge of the

lower flange

2, and 5 pins 5 electrically connected with a winding are distributed on the wiring table 4, so that a transformer can be welded on a circuit board through the pins. In addition, a wire slot 7 is also arranged between adjacent pins 5 on the wiring platform 4, so that the wires can not be exposed in the wire slot 7. In addition, a second wire groove 6 is also provided on the edge of the lower flange 2 opposite to the terminal block 4, and practically, the passing wire is a wire connection at both ends of the primary coil in the second wire groove 6.
