Abstract
A welded power transformer of an annular printed circuit board is characterized by being composed of an annular iron core, coils, a welding sheet, an outer shell and epoxy resin, the annular iron core is used for primary and secondary coil winding, the primary coil winds the inner layer of the annular iron core, the secondary coil winds the outer layer of the annular iron core, insulation should be guaranteed between the primary coil and the secondary coil, the outgoing line of the primary coil and the outgoing line of the secondary coil are respectively connected with the welding sheet in a welding mode, the annular iron core wound by the primary coil and the secondary coil is placed into the outer shell, the welding sheet is inserted into a corresponding inserting groove of the outer shell, and the inserting groove is poured with the epoxy resin to form a sealed device.
Description
Technical field
The utility model relates to a kind of annular printed substrate welded type power transformer, belongs to power electronic equipment technical field.
Background technology
But transformer is not in the market the very little power of structure can not do too high, power is very large large but small product size also and then becomes, and does not have a transformer two advantages can be rolled into one, and can be welded in circuit board.
Utility model content
The purpose of this utility model is to overcome existing methodical deficiency in discussion and provides a kind of performance, all good annular printed substrate welded type power transformers of structure.It is characterized in that: by annular core, coil, weld tabs, shell and epoxy resin form, annular core is for coiling primary and secondary coil, primary coil is wound in annular core internal layer, and secondary coil is wound in annular core skin, needs to carry out insulation between primary and secondary coil, primary and secondary lead-out wires of coil welds with weld tabs respectively, the annular core of the good primary and secondary coil of coiling is placed in shell, and weld tabs inserts in the corresponding slot of shell, becomes enclosed type device with epoxy resin encapsulated.It is little that this transformer has volume, the feature of compact conformation, and transformer overall losses is relatively low, and temperature rise is also low.
Brief description of the drawings
Fig. 1 is circuit diagram
Fig. 2 is shell figure
Fig. 3 is the installation diagram of coil and shell
Fig. 4 is the installation diagram of coil and shell
Fig. 5 finished figure
Technical problem of the present utility model can be by taking following measure to solve:
Illustrate below in conjunction with accompanying drawing:
The utility model adopts annular core to reduce product loss, and annular core adopts silicon steel core.Shell can adopt PPO fire-resistant engineering plastics, and primary and secondary coil adopts common enamelled wire coiling.
In Fig. 1, drawing is the circuit diagram after primary and secondary coil winding, and primary and secondary coil adopts Double-wire parallel wound, each two of primary and secondary lead-out wire.Both sides, tetra-angles of shell Fig. 2 are respectively useful on the slot of fixing weld tabs, can make according to actual needs both sides, each angle and have two or three slots 1, there is a cylinder 3 at shell Fig. 2 center, the built-in copper alloy nut 2 of cylinder 3, cylinder, for stationary annular magnetic core, is fixed finished product when nut welds wiring board for finished product, primary and secondary lead-out wires of coil is welded with weld tabs respectively, the assembly connecting is put into shell stably, as requested primary and secondary weld tabs is inserted in the corresponding slot 1 of shell, as Fig. 3 shows.Finally pour into epoxy resin, after epoxy material solidifies, finished product as shown in Figure 5.
The beneficial effects of the utility model are:
According to the utility model, compared with transformer in the past, the distinctive performance of annular core makes volume of transformer small and exquisite, good looking appearance, and compact conformation, accurate positioning, manufacture craft is simple, makes product no matter in the characteristic such as power stage and temperature rise, all occupy good characteristic; Be particularly suitable for high to product design dimensional requirement and large to power stage occasion.
Embodiment
As an example of the present utility model.Be summarized as follows:
M1.6 is totally 16 pins, and elementary is 3-4,5-6, and secondary is 11-12,13-14; As Fig. 3
M3.2-M25 is totally 18 pins, and elementary is 3-4,5-6, and secondary is 11-12.15-16; As Fig. 4
