Abstract
A shielding structure for preventing a mobile phone circuit board from interfering a mobile phone signal comprises a glue layer, a ferrite and a magnetic sheet which are sequentially stacked from top to bottom, wherein the upper surface of the glue layer is bonded with a circuit board; the ferrite is adhered to the lower surface of the circuit board through the adhesive layer, and is adsorbed on the magnetic sheet, so that the ferrite and the magnetic sheet can play a role in shielding, and the phenomenon that signals received by the signal receiver are unstable due to interference of the signals received by the signal receiver when the circuit board is electrified is avoided; in addition, the ferrite and the magnetic sheet are magnetically adsorbed, so that the laminating is convenient, the laminating efficiency is further improved, and the ferrite and the magnetic sheet are combined together to achieve a good shielding effect.
Description
Technical field
This utility model relates to a kind of shielding construction for preventing circuit board of mobile phone interference handset signal.
Background technology
Owing to the circuit board of mobile phone and the signal receiver of mobile phone are close, circuit board can disturb the signal that signal receiver receives in the case of energising, causes signal receiver to receive jitter.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of for preventing the shielding construction of circuit board of mobile phone interference handset signal, which obviate the circuit board interference handset signal under "on" position and cause signal receiver to receive the phenomenon of jitter.
This utility model is achieved in that a kind of shielding construction for preventing circuit board of mobile phone interference handset signal, including the glue-line being cascading from top to bottom, a ferrite and a magnetic sheet, described glue-line upper surface and circuit board bonding.
Specifically, the length of described circuit board, described glue-line, described ferrite and described magnetic sheet is 50 ± 0.05mm, and the width of described circuit board, described glue-line, described ferrite and described magnetic sheet is 35 ± 0.05mm.
The shielding construction for preventing circuit board of mobile phone interference handset signal that this utility model provides, its circuit board lower surface is stained with ferrite by glue-line, ferrite adsorbs on magnetic sheet, the effect of shielding can be played, it is to avoid the signal that circuit board disturbs signal receiver to receive in the case of energising causes signal receiver to receive the phenomenon of jitter by ferrite and magnetic sheet；It addition, ferrite and magnetic sheet use magnetic absorption, laminating is convenient, improves laminating efficiency further, and it is good that ferrite and magnetic sheet are combined shield effectiveness.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical solution of the utility model, the accompanying drawing used required in embodiment will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the schematic diagram of the shielding construction for preventing circuit board of mobile phone interference handset signal that this utility model provides.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.
As it is shown in figure 1, the offer of this utility model embodiment is a kind of for preventing the shielding construction of circuit board of mobile phone interference handset signal, including glue-line 1, ferrite 2 and the magnetic sheet 3 being cascading from top to bottom, glue-line 1 upper surface and a circuit board 4 bond.
Specifically, the length of described glue-line 1, ferrite 2, magnetic sheet 3 and circuit board 4 is 50 ± 0.05mm, and the width of described glue-line 1, ferrite 2, magnetic sheet 3 and circuit board 4 is 35 ± 0.05mm.
The shielding construction for preventing circuit board of mobile phone interference handset signal that this utility model provides, its circuit board 4 lower surface is stained with ferrite 2 by glue-line 1, ferrite 2 adsorbs on magnetic sheet 3, the effect of shielding can be played, it is to avoid the signal that circuit board 4 disturbs signal receiver to receive in the case of energising causes signal receiver to receive the phenomenon of jitter by ferrite 2 and magnetic sheet 3；It addition, ferrite and magnetic sheet 3 use magnetic absorption, laminating is convenient, improves laminating efficiency further, and it is good that ferrite 2 and magnetic sheet 3 are combined shield effectiveness.
The above is preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
