Abstract
The utility model discloses a transformer framework which comprises a framework body and a stitch base. The framework body is provided with a left column, a middle column and a right column which are connected together into one body. The left and the right columns are respectively located at the left side and the right side of the middle column. The left column is provided with a sidewall surface and a roof wall surface which are connected. The sidewall surface is connected with the middle column. The stitch base is installed on the roof wall surface, which is provided with sidewall surfaces. And at least one sidewall surface of the stitch base is located at the left side of the sidewall surface of the left column. The design of that the sidewall surface of the stitch base is located at the left side of the sidewall surface of the left column is equivalent to make glue reduction treatment to the stitch base. The utility model is convenient for enameled wire winding from the place of glue reduction to the stitch base, in which way the superposition of the winding enameled wire can be avoided. Therefore, the flatness of the winding enameled wire can be improved effectively and the transformer which is formed by winding the enameled wire can pass EMI test. The utility model can be widely used in the places of winding by using of automatic equipment with high requirement for the flatness.
Description
Technical field
The utility model relates to the transformer technology field, especially about a kind of transformer framework.
Background technology
Miniature transformer has been widely used in our daily life now, and it can be converted to low-voltage direct with normally used interchange, high pressure civil power etc., uses for some low power equipment.At present the winding of transformer all is the wire casing that is wound into transformer framework by enamelled wire or three layer insulation wire, again by the wire casing lambda line to the stitch of transformer framework.As shown in Figure 1, existing transformer framework comprises left side post 61, intermediolateral column 62 and the right post 63 that connects one, the roof face of this left side post is equipped with row's stitch seat 7, forms wire casing 8 between the adjacent needles runners, and the side wall surface 71 of each stitch seat and side wall surface 611 coplines of left side post.But there is following shortcoming in this kind transformer framework: when needs require than higher coiling evenness, will there be certain defective, the phenomenon of line overlap occur, and the smooth effect that does not reach, production efficiency is low; Also can cause simultaneously the electromagnetic interference (EMI) test of product influenced or even can not pass through, cause whole transformer in verification process, to bring very big trouble.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, provides a kind of and can improve the coiling evenness and make the transformer framework of integrated transformers by the EMI test.
The technical solution adopted for the present invention to solve the technical problems is: this transformer framework comprises support body and stitch seat, this support body has left side post, intermediolateral column and the right post that connects one, left and right side column lays respectively at the left and right side of intermediolateral column, left side post has continuous side wall surface and roof face, side wall surface connects intermediolateral column, the stitch seat is installed in the roof face, and the stitch seat has side wall surface, and the side wall surface integral body of at least one stitch seat is positioned at the left side of left side post side wall surface.
Described stitch seat has a plurality of, is respectively at outermost two second stitch seats and at least one the first stitch seat between two second stitch seats, and the side wall surface integral body of one of them first stitch seat is positioned at the left side of left side post side wall surface.
Described each side wall surface is the plane.
The side wall surface of described left side post is parallel with the side wall surface of the first stitch seat that is positioned at its left side.
The side wall surface copline of described each first stitch seat.
The side wall surface copline of the side wall surface of the described second stitch seat and left side post.
The spacing of the side wall surface of described first stitch and left side post side wall surface is 0.035mm～2.0mm.
Described left side post is parallel with the right post and all vertical with intermediolateral column.
The invention has the beneficial effects as follows, because the side wall surface of stitch seat is positioned at the left side of left side post side wall surface, promptly be equivalent to the stitch seat and subtract the glue processing, make things convenient for enamelled wire to be wound into stitch by subtracting the outlet of glue place, avoid causing that coiling is overlapping, so can effectively improve the evenness of coiling, and then the transformer that forms around last winding is tested by EMI, can be widely used in using automatic equipment coiling and evenness is required than higher occasion.

Fig. 2 is the front view of present embodiment transformer framework.
Embodiment
As shown in Figure 2, the present embodiment transformer framework has support body and a plurality of stitch seat.This support body 1 has left side post 11, intermediolateral column 12 and the right post 13 that connects one, left side post 11 and the right post 13 lay respectively at the left side and the right side of this intermediolateral column 12, left side post 11 is parallel and all vertical with intermediolateral column 12 with the right post 13, makes this support body 1 integral body be I-shaped.Left side post 11 has side wall surface 111 and roof face 112, and this side wall surface 111 is the plane with roof face 112 and intersects vertically, and this side wall surface 111 is connected with intermediolateral column 12, roof face 121 coplines of roof face 112 and intermediolateral column 12.The roof face 112 of left side post 11 is equipped with four stitch seats, these four stitch seats are respectively and are in outermost two second stitch seats 2 and two first stitch seats 3 between these two second stitch seats, are formed for the wire casing 4 of enamelled wire cabling between the adjacent needles runners.The side wall surface 21 of two second stitch seats 2 and side wall surface 111 coplines of left side post 11.Side wall surface 31 coplines of two first stitch seats 3, the side wall surface 31 of this first stitch seat 3 and the side wall surface of left side post 11 111 parallel and whole left sides that are positioned at this left side post side wall surface 111.The side wall surface 31 of this first stitch seat 3 and of the external diameter decision of the spacing of left side post side wall surface 111 according to enamelled wire, this spacing is generally 0.035mm to 2.0mm, this spacing can be by the glue that deducts the first stitch seat thick the realization.In addition, the roof face 131 of this right post 13 also is equipped with two stitch seats 5.
Because the side wall surface and the left side post side wall surface of stitch seat keep at a certain distance away, being equivalent to that promptly the stitch seat is subtracted glue handles, make things convenient for enamelled wire to be wound into stitch by subtracting the outlet of glue place, avoid causing that coiling is overlapping, so can effectively improve the evenness of coiling, and then the transformer that forms around last winding is tested by EMI, can be widely used in using automatic equipment coiling and evenness is required than higher occasion.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
