Abstract

The invention discloses power supply equipment, a planar transformer and a manufacturing method of the planar transformer. The planar transformer comprises a first magnetic core, a first secondary coil, a PCB coil, a second secondary coil and a second magnetic core which are sequentially arranged, the first secondary coil and the second secondary coil are each provided with a first pin and a secondary wiring pin, and insulating paint layers are arranged outside the first secondary coil and the second secondary coil. The first pin and the secondary wiring pin are conductive pins. According to the invention, the insulating paint layers are arranged outside the first secondary coil and the second secondary coil, the secondary coil is wrapped by the insulating paint in a paint dipping mode, the phenomenon that a copper exposed area is broken down by overhigh voltage is avoided, and the insulating paint layers are thinner than epoxy resin, so that it is facilitated that the planar transformer is ultrathin.

Description

Technical field[0001]The present invention relates to a small inductive transformer technique, and more particularly to a power supply device and a planar transformer and a method of making it.Background technique[0002]Compared with conventional transformers, the magnetic core size is large, especially the height reduction, which has a considerable attraction to the power supply (such as charger) in a strict restriction in space, so that Become a preferred magnetic component in many power supplies.[0003]As: CN209015849U, the name is: a new type of charger transformer, discloses the transformer includes the left and right cores, the left and right secondary coils, and the PCB coil between the secondary coils. During the production process, two gums were required after the secondary coil stamping, and the first inclination was mainly used to fill the slit between the secondary coil, the second injection is plastic in the secondary coil. Oxygen resin, it can be seen that the process of...
