Abstract

The invention belongs to the technical field of transformers, and particularly relates to a planar transformer and a planar transformer assembling method. The planar transformer comprises a first magnetic core, a second magnetic core and a plurality of PCB substrates, wherein first bonding side portions are arranged on the two sides of the first magnetic core; second bonding side portions are arranged on the two sides of the second magnetic core; side portion positioning bonding portions are arranged on the two second bonding side portions; the side portion positioning bonding portions and the first bonding side portions are arranged in a matched mode so that after bonding agents are arranged on the side portion positioning bonding portions, the first bonding side portions are bonded with the side part positioning bonding portions; a first middle bonding portion is arranged at the middle part of the first magnetic core; and a second middle bonding portions is arranged at the middle part of the second magnetic core. According to the invention, the magnetic cores are quickly aligned when being bonded by using the bonding agents, so the smooth bonding of the magnetic cores is realized, and production efficiency is improved; and less glue is overflowed on the side surfaces of the bonded magnetic cores after bonding, the effect of reducing the amount of the overflowed glue is realized, a subsequent treatment process for the overflowed glue is reduced, and production efficiency is further improved.

Description

Technical field [0001] The present invention belongs to the technical field of transformers, and more particularly to a planar transformer and a planar transformer assembly method. Background technique [0002] The plane transformer is a transformer with high frequency, low styling, high and high working frequency. The largest difference is the most differentiated compared to the traditional transformer is the iron core and the coil winding. The plane transformer uses a small size of the E-type, the RM type or ring ferrite core, which is usually made of high frequency power ferrite material, with lower magnetic core loss in high frequency; winding adopts multi-layer printing The circuit board is ready to form the magnetic circuit of the transformer on the high-frequency core of the windings or copper sheets. This design has a low DC copper resistance, low leakage and distributed capacitance to meet the design requirements of resonant circuits. Moreover, radio frequency interferen...
