Abstract

The invention belongs to the technical field of transformers, and in particular relates to a planar transformer and a planar transformer assembly method. The planar transformer includes a first magnetic core, a second magnetic core and a plurality of PCB substrates; Bonding side parts, second bonding side parts are provided on both sides of the second magnetic core, and side positioning bonding parts are provided on both second bonding side parts, and the side positioning bonding parts are connected to the The first bonding side part is matched and set so that after the adhesive is disposed on the side positioning bonding part, the first bonding side part is bonded to the side positioning bonding part; the first magnetic core The middle part of the second magnetic core is provided with a first middle bonding part, and the middle part of the second magnetic core is provided with a second middle bonding part. The invention enables the magnetic cores to be quickly aligned when bonding with an adhesive, realizes smooth bonding of the magnetic cores, and improves production efficiency. , reduce the follow-up treatment process of overflowing glue, and further improve production efficiency.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a planar transformer and a method for assembling the planar transformer. Background technique [0002] Planar transformer is a transformer with high frequency, low shape, small height and high working frequency. Compared with the traditional transformer, the biggest difference is the iron core and coil winding. Planar transformers use small-sized E-type, RM-type or ring-type ferrite cores, usually made of high-frequency power ferrite materials, which have low core loss at high frequencies; windings are multi-layer printed The circuit board is stacked, and the winding or copper sheet is stacked on the plane high-frequency iron core to form the magnetic circuit of the transformer. This design has low DC copper resistance, low leakage inductance and distributed capacitance, which can meet the design requirements of the resonant circuit. Moreover, due to the good magnetic shi...
