Description
Technical field
The utility model relates to electronic component technology field, is specifically related to a kind of TV transformer.
Background technology
The demand of transformer is very large, kind is more, we find in the circuit design process of television set, the heat radiation heat conductivility of current transformer is poor, and the iron core temperature that works long hours is higher, and the higher meeting of temperature is unfavorable to the coil of transformer, easily make coil aging, shorten coil useful life, simultaneously also easily on fire, cause larger potential safety hazard; Equally based on security consideration, we also find that current coil end of incoming cables and finish lead directly receive on pin by wire lead slot, and coil end of incoming cables and leading-out terminal be through processing, easily short circuit, thus puncture coil.
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 transformer, its perfect heat-dissipating, and coil end of incoming cables and leading-out terminal are difficult for short circuit simultaneously.
The utility model solves the technical scheme that its technical problem adopts: a kind of TV transformer, comprise magnetic core, magnetic core is arranged between magnetic core end face and magnetic core bottom surface, bottom, magnetic core bottom surface is fixed on substrate, between magnetic core end face and substrate by U-shaped conducting inserts heat conduction, magnetic core end face top covers heat radiation thin slice is set, and the top of described U-shaped conducting inserts contacts with heat radiation thin slice, bottom and substrate contacts;
Above-mentioned magnetic core comprises at least two iron cores, between two iron cores, is provided with I shape heat sink strip, and iron core outside is provided with inner coil, and inner coil outside is provided with outer coil, is provided with I shape heat sink strip between inner coil and outer coil;
Between above-mentioned iron core and inner coil, be also provided with corner stay;
On described substrate, be provided with wire lead slot, be also provided with pin on substrate, the coil end of incoming cables of described inner coil and outer coil and finish lead are connected to pin through wire lead slot, are set with polyurethane flexible pipe on described coil end of incoming cables and finish lead.
As a kind of preferred implementation of above-mentioned flexible pipe and core dimensions, the length of described flexible pipe is 10mm, and the folded thick of described iron core is 100mm.
As a kind of preferred implementation of above-mentioned inner coil and outer coil, described inner coil and outer coil all include insulating barrier and conductor layer.
A kind of TV transformer described in the utility model, it has the following advantages:
In the utility model, first it carrys out heat conduction by magnetic core substrate, magnetic core bottom surface directly and substrate contacts heat conduction, magnetic core end face is by heat radiation thin slice, U-shaped conducting inserts heat conduction, therefore its protective cover secure heat dissipation, the especially radiator structure of magnetic core end face of magnetic core bottom surface and magnetic end face guaranteed can secure heat dissipation away from the end face of substrate one side; The utility model is also by being arranged at least two by iron core, and coil is arranged to inner coil and outer coil, and centre by the heat conduction of I shape heat sink strip, has formed reliable heat dissipation channel respectively, therefore compares traditional structure, and its heat-sinking capability is stronger; The utility model arranges wire lead slot and pin on substrate, on coil end of incoming cables and finish lead, be set with polyurethane flexible pipe, coil end of incoming cables and the finish lead of suit flexible pipe are spaced from each other, play insulating effect, polyurethane flexible pipe is high temperature resistant simultaneously, prevent that overtension from puncturing coil, extend the useful life of transformer.
