Description
Technical field
The utility model relates to wireless charger field, particularly a kind of mounting structure of wireless charger resonant capacitance.
Background technology
Along with the rise for wireless charging technology, wireless charging device also becomes more and more popular.In order to make wireless charger lightening, the resonant capacitance of existing wireless charger adopts the SMD patch capacitor of NPO material usually, and in order to solve the heating problem of self, many patch capacitors are needed to carry out parallel connection, although the method solves the lightening problem of wireless charging device very well, but because the patch capacitor of NPO material is expensive, it considerably increases the cost of wireless charger.Therefore, prior art haves much room for improvement.
Utility model content
For overcoming the deficiencies in the prior art and Problems existing, the utility model provides a kind of mounting structure of wireless charger resonant capacitance, and it effectively can reduce the cost of wireless charger and reduce the whole height of wireless charger.
The utility model is achieved through the following technical solutions: a kind of mounting structure of wireless charger resonant capacitance, the pcb board comprising wireless charger and the resonant capacitance be installed on pcb board, described resonant capacitance is metal film electric capacity, described pcb board is provided with the pad of the pin for welding described metal film electric capacity, position near described pad on described pcb board is provided with a perforate, the shape size of described perforate mates with the shape size of described metal film electric capacity, and described metal film electric capacity is positioned at described perforate.
Preferably, a surface of described metal film electric capacity flushes with the bottom surface of described pcb board; The overall rounded structure of described pcb board.
The mounting structure of the wireless charger resonant capacitance that the utility model provides, it replaces the patch capacitor of existing NPO material by employing metal film electric capacity, and by perforate on pcb board metal film electric capacity is arranged in this perforate, while the cost effectively reducing wireless charger, also effectively reduce the height of product.

Fig. 1 is the structural representation of pcb board described in the utility model embodiment;
Fig. 2 is the mounting structure schematic diagram of resonant capacitance described in the utility model embodiment;
Fig. 3 is the cutaway view at A-A place in Fig. 2.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As illustrated in the accompanying drawings from 1 to 3, a kind of mounting structure of wireless charger resonant capacitance, the pcb board 10 comprising wireless charger and the resonant capacitance be installed on pcb board 10, described resonant capacitance is metal film electric capacity 20, described pcb board 10 is provided with the pad 12 of the pin 21 for welding described metal film electric capacity 20, position near described pad 12 on described pcb board 10 is provided with a perforate 11, the shape size of described perforate 11 mates with the shape size of described metal film electric capacity 20, and described metal film electric capacity 20 is positioned at described perforate 11.In the present embodiment, described pcb board 10 is preferably overall rounded structure.
In prior art, the resonant capacitance material of wireless charger is the SMD patch capacitor of NPO, and need many parallel connections, and the present embodiment replaces many patch capacitors in parallel by adopting a metal film electric capacity 20, and by arranging a perforate 11 on pcb board 10, and described metal film electric capacity 20 is arranged in this perforate 11, make it reach to replace the performance before patch capacitor and structure, and the cost of electric capacity only has original 1/24, the mounting structure of the resonant capacitance therefore adopting the present embodiment to provide effectively reduces the cost of wireless charger.In order to reduce the height of whole product better, a surface of described metal film electric capacity 20 flushes with the bottom surface of described pcb board 10, as shown in Figure 3.
Above-described embodiment is preferably implementation of the present utility model, is not to restriction of the present utility model, and under the prerequisite not departing from inventive concept of the present utility model, any apparent replacement is all within protection range of the present utility model.
