Further, the magnetic core is in mountain font, and the projection in the centre position of the mountain shaped magnetic core is cylindrical column,
The top surface of the top surface of the cylindrical column and the magnetic core is located in approximately the same plane.
Further, the width of the mountain shaped magnetic core both sides is not less than the diameter of the cylindrical column.
Further, the position that the coil is in contact with the magnetic core is provided with insulating part.
Further, the insulating part is the U.S. paper of promise.
Further, the wire outer rim of the coil is arranged with sleeve pipe.
Further, the outer rim of the transformer is coated with insulated paint.
Compared with prior art, beneficial effect is the utility model：A kind of charging pile transformer of the present utility model, its
Including bottom plate, two magnetic cores and coil.The both ends and centre position of the magnetic core extend convex toward the same side direction
Post, described two magnetic cores are symmetrical above and below to be set, and the rectangular configuration with toroidal cavity is collectively forming, by the coil around the home in institute
On the periphery for the projection for stating magnetic core centre position, replace skeleton to rise so as to the rectangular configuration that is formed using two magnetic cores and hold
Load is acted on.In use, at the corresponding jack being inserted directly into using the pin below bottom plate on pcb board.The transformer is cancelled
The magnetic core net sectional area increase of transformer under the use of skeleton, same size, saturation flux density BS values increase, because
This, when reaching identical voltage, can reduce the number of turn using coil, so as to reduce electric current compared to the transformer for having skeleton
Loss, improves electromagnetic conversion efficiency.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
As depicted in figs. 1 and 2, a kind of charging pile transformer 100 provided for the utility model embodiment, it includes bottom plate
1st, two magnetic cores 2 and coil 3.
The both ends and centre position of the magnetic core 2 are extended on projection, described two magnetic cores 2 toward the same side direction
Under be symmetrical arranged, be collectively forming the rectangular configuration with toroidal cavity (not marking).The coil 3 is located at the toroidal cavity
It is interior, and around the home on the periphery of the projection in the centre position of magnetic core 2, the rectangular configuration formed by described two magnetic cores 2
Instead of skeleton as bearing structure, the transformer under same size, it is possible to reduce because skeleton shared space in itself, is reserved
More spaces are to magnetic core 2, so that the net sectional area increase of the magnetic core 2, the net sectional area of the magnetic core 2 increases
Greatly, then saturation flux density BS values increase.Therefore, in the case where needing to reach identical voltage, the coil of the transformer 100
The number of turn required for 3 is relatively fewer, so, and the loss of electric current will be reduced, so as to improve the electromagnetic conversion of the transformer 100
Efficiency.
The bottom plate 1 is fixed on the bottom of the rectangular configuration, and the bottom plate 1 is provided with some for connecting PCB board
Pin 11, the pin 11 is electrically connected with the coil 3.In use, some pins 11 to be directly plugged on to the phase of pcb board
Answer at jack, it is easy to use.
Reference picture 3 and Fig. 4, the magnetic core 2 are in mountain font, and the projection in the centre position of the mountain shaped magnetic core 2 is cylinder
