<p>The present invention relates to a transformer. The present invention includes a bobbin having multiple coil winding parts divided by multiple coil partitions, having a fixing plate, in which a connection pin is fixed by being separated in a longitudinal direction, formed in a lower part of the outermost coil partitions among multiple coil partitions, and having an insertion hole formed to fix a ferrite core in the center of the coil winding parts; and the ferrite core fixed on the insertion hole penetrating the center of the coil winding parts. Through the formation of the transformer, in which the ferrite core is formed in the same length as the insertion hole or predetermined longer length to protrude to both sides of the insertion hole so that the ferrite core is inserted into the insertion hole to be fixed and installed by tight-fit, the ferrite core is easily fixed and installed without an extra fixing member, and damage to an electronic circuit or transformer, caused by current leak between the ferrite core and a coil, or malfunction of the electronic circuit, caused by electromagnetic wave, is stably prevented. And as the exposure of the ferrite core is minimized to minimize the influence of external temperature on the ferrite core, the output fluctuation of the transformer, caused by the influence of external temperature, is stably prevented.</p> |
