The structure for preventing core flow of flyback trans former

摘要

The present invention relates to a core flow prevention structure of the flyback transformer so as to prevent voltage fluctuations due to the flow of the flyback transformer fixation core after winding the coil to the low-pressure bobbin fastening the core such that the magnetic force is generated in a conventional flyback the transformer is cured by the contact preventing the flow of the fixed core to be injected into the bond to the core fastening portion the upper and lower sides when sikyeoteul fastening contact causes one side of the core opposite to each other through the core fastening portion the upper and lower sides of the low-pressure bobbin coil winding core that the flow of the anti-bar, since the fastening flyback transformer the contact facing each other during the flow before the injection of the bonds cured the core from flowing into the upper and lower stand there is a problem in that the voltage variations in the flyback transformer.; The subject innovation is to form the clamping groove inside the lower body of the low pressure bobbin, signed by extruding a fastening protrusion formed in the core is fastened to the lower side of the low pressure bobbin body to be to penetrate the core toward the core fastening portion above and below the low-pressure bobbin opposite to each other fixed applied to the flyback transformer that allows the fastening protrusion formed in the body of the core can be so fastened fixed to the engaging groove formed in the lower body of the low pressure bobbin standing in the core is prevented from flowing in the low pressure bobbin so prevent variation in voltage when do.
