Vertical-type transformer structure

Abstract

The invention discloses a vertical-type transformer structure. The vertical-type transformer structure is different from a transformer structure in prior art. The vertical-type transformer structure is characterized in that an accommodating member is utilized for accommodating a bobbin which warps a primary-side coil. According to the vertical-type transformer structure, after a primary-side iron core is combined with the bobbin which is accommodated in the accommodating member, the accommodating member supplies effective insulation to the primary-side iron core so that a portion between the primary-side iron core and an adjacent electronic assembly can satisfy a related safety regulation. Furthermore, because the bobbin of the primary-side coil is accommodated and packaged by the central accommodating part of the accommodating member, after high voltage is input into the primary-side coil, the accommodating member supplies effective insulation to the primary-side coil, thereby preventing direct bypass of high voltage through an adjacent secondary-side iron core to the secondary-side coil.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a vertical transformer structure. Background technique [0002] With the evolution and development of electronic products, different electronic products need to be driven by different power supply devices; therefore, manufacturers of power supply devices are actively trying to develop various transformer structures for corresponding applications in various power supply devices . [0003] A simple transformer is composed of a first conductor and a second conductor, and when an indeterminate current passes through the first conductor, a fluctuating magnetic field is generated on the first conductor; then, based on the principle of electromagnetic mutual inductance, the fluctuation The magnetic field will cause an induced electromotive force to be generated on the second conductor, and then form a potential difference between the first conductor and the second conductor, ...

Problems solved by technology

[0009] (2) In addition, in the design of the transformer structure 1' in the prior art, the part where the secondary side coil 122' is drawn to the second terminal group 115' is obviously too close to the second E-shaped iron core 13a', resulting in The creepage distances of the transformer structure 1' in the existing technology cannot meet the relevant safety regulations

It is conceivable that the process of winding and covering the first E-shaped iron core 13' and the second E-shaped iron core 13a' with insulating tape cannot be completed by automatic equipment, so the process of winding and covering the insulating tape must be done manually. can be completed, so that the manufacturing cost of the transformer structure 1' in the prior art is increased
