Description

Transformer {TRANSFORMER}

The present invention relates to a transformer. Conventional general transformers using Mylar insulation plates could not be fixed at a fixed position, and were unstable due to the lack of internal pressure due to the increase in shrinkage rate due to temperature rise.

The main purpose of the present invention is to install one plastic fixing bracket on the lower iron core to accurately fix the position of the transformer, flatten the pin to reach the precision SMD standard, and also to set the breakdown voltage value of the iron core and coil. It improves the efficiency of the transformer by increasing the dark synthesis by fixing the flat coil and the circuit board, and stacking two sets of flat coils.

1 and 2, the present invention is the upper and lower core core (1, 2), plastic fixing bracket (3), circuit board (4), mylar insulation plate (5), flat coil (6) and plastic The insulating plate 7 etc. are comprised. Components such as a circuit board (PCB Board) 4, a mylar insulating plate 5, a flat coil 6 and a plastic insulating plate 7 are laminated and bonded between the upper and lower iron cores 1 and 2. At the center of the horseshoe-shaped upper and lower iron cores (1, 2) are provided with one cylinder (11, 21), respectively, can be connected to each other. The center openings 41, 51, 61, and 71 of the circuit board 4, the mylar insulation plate 5, the flat coil 6, and the plastic insulation plate 7 are sequentially aligned with the cylinders of the upper and lower iron cores 1, 2. 11, 21), and its features are as follows.

One plastic fixing bracket 3 is stacked on the lower iron core 2, and the central opening 31 of the plastic fixing bracket 3 is coupled to the cylinders 11 and 21 of the upper and lower iron cores 1 and 2. do. When the plurality of pins 32 are properly disposed on the plastic fixing pedestal 3 and fitted into the plurality of openings 42 on the circuit board 4 corresponding thereto, the pins 32 and the circuit board 4 are connected to the electric circuit. Will form. Position fixing means 33 is formed at each corner of the bottom of the plastic fixing pedestal (3).

The flat coil 6 of the present invention is formed by stacking two sets of coils intersecting each other, thereby increasing the dark synthesis and improving the efficiency of the transformer. The flat coil 6 is covered with one plastic insulation plate 7 instead of the mylar insulation plate.

As described above, the present invention installs one plastic fixing pedestal on the lower iron core to accurately fix the position of the transformer, flatten the pin to reach the precision SMD standard, and also the internal pressure of the iron core and the coil. It can increase the value, fix the flat coil and the circuit board, and improve the efficiency of the transformer by increasing the dark synthesis by stacking two sets of flat coils.
