Technical Field
[0001] The utility model relates to the technical field of transformer skeletons, in particular to a transformer skeleton for convenient coil winding. Background Art
[0002] The transformer skeleton, also known as the transformer wire frame, is an important part of the transformer structure. The main functions of the skeleton are: first, to provide space for the copper wire in the transformer to wind, and the part of the skeleton that provides this function is called the winding slot; second, to fix the magnetic core in the transformer, and the part where the skeleton inserts the magnetic core is called the magnetic core hole, which can be divided into round holes, square holes, and special-shaped holes, which are determined by the matching magnetic core. In order to improve economic benefits, most manufacturers will use insulating materials such as epoxy resin, red phosphorus and PA66 nylon. In order to facilitate the efficient production of transformer skeletons, a transformer skeleton that is convenient for winding coils is designed.
[0003] A transformer skeleton is disclosed in publication number CN206497820U. Although the utility model makes the transformer production convenient, efficient, high in safety factor and low in cost.
[0004] However, the transformer skeleton has the following disadvantages: 1. It is not convenient to provide elastic tension during winding, which makes the copper coil more compact and convenient after winding, effectively reduces eddy current loss, improves magnetic conductivity, and at the same time, compact winding can increase the surface area of the coil, which helps to dissipate heat more effectively. This is very important for the thermal management of the transformer when it is running for a long time or under high load; 2. The shape of the transformer skeleton is relatively complex, which makes production more troublesome. Utility Model Content
[0005] The technical problems to be solved by the utility model are as follows: it is inconvenient to provide elastic tension during winding, and to manufacture the transformer skeleton by simple assembly and splicing.
[0006] The purpose of the utility model can be achieved through the following technical solutions:
[0007] A transformer skeleton for convenient coil winding comprises a winding frame, both sides of the winding frame are fixedly connected to limit blocks, the upper and lower sides of the winding frame are provided with embedded grooves, the interior of the embedded grooves is adapted to be clamped with expansion components, both sides of the winding frame are fixedly installed with triangular clamping parts, one side of the winding frame is clamped with an A connecting piece, the other side of the winding frame is clamped with a B connecting piece, the surfaces of the A connecting piece and the B connecting piece are provided with two groups of probe grooves, the interiors of the two groups of the probe grooves are clamped with triangular clamping pieces, wherein one end of the two groups of the triangular clamping pieces are fixedly connected to an A conductive bar, wherein one end of the other two groups of the triangular clamping pieces are fixedly connected to a B conductive bar.
[0008] As a further solution of the utility model: there are four limit blocks, and the four limit blocks are divided into two groups and are fixedly connected to the two sides of the winding frame in a straight line shape.
[0009] As a further solution of the utility model: the expansion component includes splicing pieces clamped at both ends of the embedded groove, and stainless steel spring pieces are fixedly installed on the inner sides of the two splicing pieces.
[0010] As a further solution of the utility model: the number of the triangular clamping parts on a single side is two, and the two triangular clamping parts are symmetrically fixed on the two sides of the winding frame in a straight line.

When winding the coil, the elastic effect of the stainless steel spring is used to expand the wound coil, which is convenient for winding the copper wire, and improves the filling density and arrangement density of the wound coil, thereby reducing the eddy current loss of the transformer during use and improving the magnetic conductivity of the transformer. At the same time, tight winding can increase the surface area of the coil, which helps to dissipate heat more effectively. BRIEF DESCRIPTION OF THE DRAWINGS
