Side, the upper cover and pedestal integrated die-casting form, and the upper cover and pedestal are respectively magnet material structure, the winding card
It sets in pedestal, the connection terminal is connected to the two sides of winding.
The upper cover and pedestal are respectively ferro-silicium or iron-based magnetic powder core material structure in one of the embodiments,.
The winding quantity in the pedestal is at least 2 groups in one of the embodiments, and every group of winding two sides respectively correspond
Connect connection terminal.
The connection terminal upper end extends to form weld part to chassis interior bending in one of the embodiments, described
Connection terminal lower end is bent to pedestal lower end extends interconnecting piece.
The weld part is connect with winding by spot-welded in one of the embodiments,.
The connection terminal is the tin plating terminal construction of copper in one of the embodiments,.
In conclusion the utility model be integrally formed transformer by by winding setting in the molding upper cover of integrated die-casting and
In pedestal, using upper cover and the magnet material structure of pedestal, so that product has the Magnetic circuit characters being closed completely, shield effectiveness
Good, structure is simple, reduces design cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model is integrally formed transformer；
Fig. 2 is the structural schematic diagram that the utility model is integrally formed after the hiding upper cover of transformer.
Specific embodiment
For the feature, technological means and specific purposes achieved, function that can further appreciate that the utility model, below
The utility model is described in further detail in conjunction with attached drawing and specific embodiment.
As depicted in figs. 1 and 2, it includes upper cover 1, pedestal 2, winding 3 and connecting pin that the utility model, which is integrally formed transformer,
Son 4, the connection terminal 4 is held between upper cover 1 and pedestal 2 and is bonded the side that pedestal 2 is arranged in, the upper cover 1 and bottom
Seat 2 integrated die-castings molding, the upper cover 1 and pedestal 2 are respectively magnet material structure, and specifically, the upper cover 1 is divided with pedestal 2
It Wei not ferro-silicium or iron-based magnetic powder core material structure；In pedestal 2, the connection terminal 4 is separately connected for 3 holding of winding
In the two sides of winding 3.
3 quantity of winding in the pedestal 2 is at least 2 groups, and every group of 3 two sides of winding are connected respectively connection terminal 4, root
Multiple windings 3 can be set according to route actual needs, wherein the winding 3 can be by air core coil and being set in air core coil
And it is wrapped in ferro-silicium or iron-based magnetic powder core pressing composition outside air core coil；The molding upper cover 1 of integrated die-casting and pedestal 2 have
There are the Magnetic circuit characters being closed completely, basic without scattered magnetic flux, shield effectiveness is good, reduces design cost in this way, reduces circuit
Component simplifies circuit design, saves space, simple production process, more for practicability.
4 upper end of connection terminal extends to form weld part 41 to 2 internal bend of pedestal in one of the embodiments,
4 lower end of connection terminal is bent to 2 lower end of pedestal extends interconnecting piece 42, and the weld part 41 passes through spot-welded with winding 3
Connection, the interconnecting piece 42 is for being electrically connected external circuit module.
The connection terminal 4 is the tin plating terminal construction of copper in one of the embodiments, and certain the utility model is simultaneously unlimited
In this, other any 4 materials of connection terminal that can achieve same or similar effect, such as copper tip etc..
When the utility model specifically manufactures, since upper cover 1 and pedestal 2 are magnet material structure, first by 3 two sides of winding point
Not Han Jielianjie terminal 4, then the type that winding 3 is placed in die casting is intracavitary, and finally magnet material is added into die casting
It is pressed, completes manufacturing process, the clamping of connection terminal 4 between upper cover 1 and pedestal 2 and is bonded setting in pedestal 2 after shaping
Side；The molding upper cover 1 of integrated die-casting and pedestal 2 have the Magnetic circuit characters being closed completely, basic without scattered magnetic flux, shielding effect
Fruit is good, reduces design cost in this way, reduces circuit components, simplifies circuit design, saves space, production technology letter
