Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and more specifically, to a combined new transformer skeleton. Background Art

[0002] At present, due to high input conditions, some transformers have very strict requirements for safety distances, and at the same time require low leakage inductance, high efficiency, and miniaturization in terms of the space occupied by the transformer. To solve the problem of safety distance for such transformers, generally, the size of the winding skeleton is increased to meet the requirements, or three-layer insulated wire is used instead of ordinary enameled wire for winding, and edge tapes are added on both sides of the skeleton. However, this will cause the outer size of the transformer to become larger. When using three-layer insulated wire for winding or adding edge tapes at the edges of the winding, the common problems are that the winding space is increased, the space utilization rate of the winding is not high, the leakage inductance between the primary and secondary windings is increased, thereby reducing the conversion efficiency of the transformer, and at the same time, the material cost and manufacturing cost of the three-layer insulated wire and the edge tapes are very high.

[0003] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0034] In actual application, for assembly, first, the mother sleeve 2 and the son sleeve 3 are wound with ordinary enameled wire to make full use of the winding space. Then, the son sleeve 3 is placed in the annular placement groove 7 of the mother sleeve 2. Subsequently, the mother sleeve 2 is placed in the installation shell 1, so that the positioning post 5 on the installation shell 1 is inserted into the positioning groove 6 on the mother sleeve 2. Then, the fixed cover 4 is covered on the installation shell 1. During this process, the operator first pulls the pull block 25 to drive the pull rod 23 to move. The pull rod 23 drives the limit pin 26 to leave the tooth groove on the limit gear 27 through the slider 22. At this time, the second spring 24 is in a compressed state, and the limit of the limit gear 27 is released.

At this time, the operator can cover the fixed cover 4 on the installation shell 1, so that the L-shaped insertion plate 12 on the fixed cover 4 is inserted into the insertion slot 11. Then, the operator pulls the pull block 25 again to make the limit pin 26 disengage from the tooth groove of the limit gear 27, and the limit of the rotating shaft 14 is released. The first spring 18 resets and drives the limit rod 17 to insert into the insertion slot 11 and into the limit slot on the L-shaped insertion plate 12 to limit it. By assembling and combining the transformer skeleton and then adjusting the edge width of the skeleton to meet the safety distance, at the same time, the wire of the son sleeve can be wound with ordinary enameled copper wire, which reduces the winding space, can meet the safety distance, can also reduce the distance between the son sleeve winding and the mother sleeve winding, thereby reducing the leakage inductance and improving the efficiency of the transformer. Through the combined skeleton, the safety distance of the transformer itself can be maximized under the same volume, and at the same time, the leakage inductance of the transformer can be reduced, effectively improving the efficiency of the transformer. By setting the limit component, the fixed cover can be quickly disassembled and assembled, reducing the assembly time of the transformer skeleton and facilitating subsequent maintenance or replacement of the mother sleeve or son sleeve.

[0035] In summary, by means of the above technical solutions of the present invention, by assembling and combining the transformer skeleton and then adjusting the edge width of the skeleton to meet the safety distance, at the same time, the wire of the son sleeve can be wound with ordinary enameled copper wire, which reduces the winding space, can meet the safety distance, can also reduce the distance between the son sleeve winding and the mother sleeve winding, thereby reducing the leakage inductance and improving the efficiency of the transformer. Through the combined skeleton, the safety distance of the transformer itself can be maximized under the same volume, and at the same time, the leakage inductance of the transformer can be reduced, effectively improving the efficiency of the transformer. By setting the limit component, the fixed cover can be quickly disassembled and assembled, reducing the assembly time of the transformer skeleton and facilitating subsequent maintenance or replacement of the mother sleeve or son sleeve.
