Abstract
A transformer with a bobbin for preventing a crack may include a lower core configured to be provided with a lower assembling jaw, a bobbin for preventing a crack configured to have a center rib which is provided with a lower core crack preventing part inserted into the lower assembling jaw and an upper core crack preventing part formed at an opposite side to the lower core crack preventing part, having a predetermined thickness, a bus bar configured to penetrate through the center rib, an insulating plate configured to be stacked on an upper end surface of the bus bar, and an upper core inserted into the insulating plate and the bus bar and inserted into the upper core crack preventing part.
Claims14
A transformer, comprising:
- a lower core configured to be provided with a lower assembling jaw;
- a bobbin configured to have a center rib which is provided with a lower core crack preventing part inserted into the lower assembling jaw and an upper core crack preventing part formed at an opposite side to the lower core crack preventing part, having a predetermined thickness;
- a bus bar configured to penetrate through the center rib;
- an insulating plate configured to be stacked on an upper end surface of the bus bar;
- and
- an upper core inserted into the insulating plate and the bus bar and inserted into the upper core crack preventing part.
A transformer comprising:
- a lower magnetic core comprising a lower protrusion;
- a bobbin comprising a cylindrical wall;
- a bus bar surrounding the cylindrical wall;
- an upper magnetic core comprising a upper protrusion, wherein the lower assembling protrusion and the upper assembling protrusion are inserted in the cylindrical wall such that the cylindrical wall surrounds the lower and upper protrusions;
- and
- a spacer attached to the cylindrical wall and positioned within the cylindrical wall between the lower and upper protrusions such that the lower and upper protrusions are spaced from each other.
