Specific embodiment
As shown in Figures 1 to 4, a kind of flat transformator, including transformer framework and it is installed on transformer framework
Magnetic core, the transformer framework include the primary skeleton 1 located at transformer primary and the secondary bone located at transformer secondary
Frame 2, is split-type structural between the primary skeleton and secondary framework, and secondary framework 2 is nested in primary skeleton 1, and adopt
It is fixed together with the matching of concave convex button 3.So, not only isolate primary and secondary, also meet the requirement of flattening, miniaturization, make
Space availability ratio is maximized.
Wherein, as depicted in figs. 1 and 2, the primary skeleton 1 be rectangular flat shape structure, the center of the primary skeleton
The inner cavity 11 being put into for magnetic core is provided with, the length both sides of the primary skeleton are provided with the projecting surface for protruding from indent resonator end surface
12, the projecting surface is provided with recess 121 towards inner cavity side, and the width both sides of the primary skeleton form disconnected between projecting surface
Fluting 13.Length the first side projecting surface of the primary skeleton is provided with the buckle 122 stretched in recess in the oral area both sides of recess,
The length both sides of primary skeleton are provided with the hanging wire foot 123 vertical with projecting surface, further, primary bone in the corner of projecting surface 12
The length both sides of frame correspond to hanging wire foot 123 and are provided with hanging wire groove 125, to facilitate hanging wire,.
Length the second side projecting surface of primary skeleton is provided with depressed part 124 between recess 121 and the second side end, increases
And the primary, creepage distance of magnetic core, make the transformator safer under limited space, meet safety requirement.
The back side of the primary skeleton 1 is provided with concavo-convex enhancing structure 16 in length both sides.Concavo-convex enhancing structure 16 is located at length
Degree both sides, middle is the first gum groove, is easy to tape.Concavo-convex enhancing structure 16 is overall rectangular, and edge protuberance, centre are provided with
Multiple rectangles it is recessed.This is that, as primary skeleton is longer, primary skeleton edges are relatively thin broken, can be made using this structure
