Description
Technical field
The utility model relates to electronic component technology field, is specifically related to a kind of TV switch transformer.
Background technology
Along with the lightening development of TV, for switch transformer for TV, its flattening becomes trend, existing TV is generally divided into two parts by coil rack with switch transformer, on two parts, winding and output winding are inputted in coiling respectively, this structure makes transformer leakage inductance bigger than normal, and coupling performance is poor; Meanwhile, the leading foot structure of existing switch transformer causes draws pin and directly welds formation pad, thereby transformer thickness increases, be unfavorable for flattening, affect the problem that also has winding construction of switch transformer flattening development, the wrapped repeatedly crossover of lead-out wire of existing many groups, does not have fixing winding displacement passage, therefore makes line bag height increase.
Summary of the invention
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of TV switch transformer, and it is flattening more, and leakage inductance is little simultaneously, and coupling effect is good, good insulation preformance.
The utility model solves the technical scheme that its technical problem adopts: a kind of TV switch transformer, comprises coil rack, the winding section in the middle of described coil rack comprises and the lead division of both sides; On winding section, first coiling one deck is inputted winding, and after input winding outer wrap one deck insulating tape, coiling one deck is exported winding again, the outside parcel equally of output winding one deck insulating tape;
Inside, described winding section is provided with cavity, and the cross section of described winding section is flat rectangle, and magnetic core is E type structure, and the external part in the middle of it inserts in the cavity of winding section, and the external part of both sides is by input winding and export winding around getting up;
Both sides, top, described winding section are provided with winding head buttock line and draw ditch, and it is to be formed by the gap between paired projection that winding head buttock line is drawn ditch, and the line end to end of each winding is drawn ditch by line end to end separately and is connected to respectively the leading foot being arranged on lead division; The end face of described lead division is provided with multiple wire lead slots;
Above-mentioned leading foot is L shaped, and its cross section is flat, and stretch out from lead division both sides its one end, and the other end stretches out from lead division end face.
One as above-mentioned insulating tape is preferred, and described insulating tape is epoxy adhesive tape.
As a kind of embodiment of above-mentioned input winding and output winding, described input winding and output winding are enamelled wire, and this enamelled wire comprises twisted wire and sleeve pipe.
A kind of TV switch transformer described in the utility model, it has the following advantages:
The utility model TV switch transformer, directly overlaps input winding and output winding, and is isolated and insulated by insulating tape, and the leakage inductance of switch transformer is reduced, and coupling effect is good, meanwhile, the utility model TV is flat structure with the coil rack of switch transformer, on it, be provided with winding head buttock line and draw ditch, realize evenly arranging of the each winding of switch transformer with this, while avoiding winding the line, rise, tail head juxtaposition, thereby reduce the height of coil body, the utility model also makes welding position be arranged on the transformer side of leading foot by the L shaped leading foot of flat, can avoid so directly welding leading foot bottom part and increase transformer total height, do not affect again the installation of E type magnetic core, thereby further reduce the thickness of transformer.
