Abstract
The utility model discloses a radio frequency card antenna plate sensing structure of an iron shell POS machine. The radio frequency card antenna plate sensing structure of the iron shell POS machine includes an iron shell and a radio frequency card antenna plate. The radio frequency card antenna plate is disposed in the iron shell. The surface of the iron shell is provided with a gap corresponding to the radio frequency card antenna plate. A plastic covering plate is arranged corresponding to the gap. By adopting the structure in the utility model, not only the metal shell having a nice appearance can be remained, but also the communication between a radio frequency card and the radio frequency card antenna plate is not influenced. And the radio frequency card antenna plate sensing structure of the iron shell POS machine in the utility model is simple in structure and convenient for spreading.
Description
Technical field
The utility model relates to the radio-frequency card antenna plate induction structure of iron-clad POS machine.
Background technology
Use the demand of radio-frequency card more and more on the POS machine; The use principle of radio-frequency card is: in POS machine shell, the radio-frequency card antenna plate is set; Its antenna plate is to be formed by special coil winding; Coil electricity produces the AC magnetism flux, and radio-frequency card is through the AC magnetism flux that produces with the radio-frequency card antenna plate intercouple transmission of power and signal.Because of the shell of existing P OS machine is a plastic housing, the radio-frequency card antenna plate is located in the plastic casing, and the AC magnetism flux that the radio-frequency card antenna plate produces can directly penetrate plastic casing, does not influence the use of radio-frequency card.
Because of existing P OS machine shell changes iron-clad into, because the magnetic field that the coil of radio-frequency card antenna plate produces can produce eddy current on the iron-clad surface, absorb magnetic field energy, because magnetic flux can't be walked around the full wafer iron-clad, radio-frequency card can't obtain energy, causes and can't read radio-frequency card.
Summary of the invention
In order to overcome the deficiency of prior art, the purpose of the utility model is to provide a kind of radio-frequency card antenna plate induction structure that can realize the iron-clad POS machine of radio-frequency card and the proper communication of radio-frequency card antenna plate.
The radio-frequency card antenna plate induction structure of the utility model iron-clad POS machine, it comprises iron-clad and radio-frequency card antenna plate, and the radio-frequency card antenna plate is located in the iron-clad, and the corresponding radio-frequency card antenna plate in iron-clad surface is provided with breach, to being provided with plastic cover plate by breach.
Said gap edge is wider than the edge of radio-frequency card antenna plate.
Adopt the structure of the utility model; Corresponding radio-frequency card antenna plate is provided with breach on the iron-clad surface; Breach is provided with plastic cover plate; So the AC magnetism flux that the radio-frequency card antenna plate produces can not shielded by iron-clad, can penetrate plastic cover plate and radio-frequency card smoothly and realize proper communication, the iron-clad of POS machine is reduced to minimum to the influence of radio-frequency card antenna plate.Adopt such structure, not only can keep adopting metal shell more attractive in appearance, and can not hinder communicating by letter of radio-frequency card and radio-frequency card antenna plate, simple in structure, be convenient to promote.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the radio-frequency card antenna plate induction structure of the utility model iron-clad POS machine.
Embodiment
As shown in Figure 1; The radio-frequency card antenna plate induction structure of the utility model iron-clad POS machine, it comprises iron-clad 1 and radio-frequency card antenna plate 2, radio-frequency card antenna plate 2 is located in the iron-clad 1; Iron-clad 1 surperficial corresponding radio-frequency card antenna plate 2 is provided with breach 3, to being provided with plastic cover plate 4 by breach 3.
Adopt above structure; Be provided with breach 3 in iron-clad 1 surperficial corresponding radio-frequency card antenna plate 2; Breach 3 is provided with plastic cover plate 4, so the AC magnetism flux that radio-frequency card antenna plate 2 produces can not penetrated plastic cover plate 4 and realize proper communication with radio-frequency card by iron-clad 1 shielding smoothly.
The edge of radio-frequency card antenna plate 2 is wider than at said breach 3 edges, like this influence of 1 pair of radio-frequency card antenna plate 2 of iron-clad of POS machine is reduced to minimum.
Claims (2)
1. the radio-frequency card antenna plate induction structure of iron-clad POS machine, it is characterized in that: it comprises iron-clad and radio-frequency card antenna plate, and the radio-frequency card antenna plate is located in the iron-clad, the corresponding radio-frequency card antenna plate in iron-clad surface is provided with breach, to being provided with plastic cover plate by breach.
