Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal case and a portable terminal on which an RF card is mounted, and more particularly, to a portable terminal case and a portable terminal to be mounted on a detachable case which is easy to replace a thin RF card and is inexpensive.
Generally, non-contact RF card among chip embedded RF card is used as security card key to control access or as a micro payment method for paying the subway or bus fee, and there is a loop type antenna and wireless electronic chip inside. While communicating with the card reader installed at the place, the identifier information and the use price information registered in the electronic chip are read and transmitted to the financial server or the security system through the communication means.
In the above-mentioned small payment RF card, a user first receives a service, and then the price information of the provided service and the unique identifier information of the electronic chip embedded in the RF card are immediately or artificially transmitted to the financial server. As a result, after a certain time has passed (payment date), the payment is made by postpay method.
However, in recent years, the harmfulness of electromagnetic waves has been known through various papers and experiments, and in the case of mobile communication terminals, much attention has been focused on electromagnetic hazards than any other electronic products. The mobile communication terminal is applied to apply various kinds of electromagnetic wave blocking means such as a blocking case. In the case of the mobile communication terminal with the RF electronic chip and the loop antenna, the above-described electromagnetic wave blocking means is applied to the loop antenna and the card. RF communication for forming induced electromotive force between readers is disturbed, and the recognition distance is shortened. As a result, communication is incomplete if the terminal is not brought closer to the card reader.
Therefore, in the related art, the RF electronic chip is embedded in a wireless communication terminal, that is, the mobile communication terminal, and the loop antenna is installed in the battery, so that a sufficient recognition distance is obtained regardless of the electromagnetic wave blocking means in the mobile communication terminal. The battery to be mounted not only generates electromagnetic waves by itself but also basically contains a metal component, thereby preventing a sufficient recognition distance as it interferes with RF transmission and reception.
The present invention relates to a built-in RF card attached to a conventional mobile phone to solve the problem of recognition distance, Korean Patent Publication No. 2003-35265 "Built-in contactless electronic card" and 2003-17590 "Mobile communication terminal built-in traffic card" Etc.
Briefly describing the first conventional electronic card, as shown in FIG. 1, the built-in contactless

On the other hand, a brief description of the electronic card according to the second prior art, as shown in Figure 2, is embedded in the
However, the conventional methods are all built in the cell phone or the battery, for example, there is a problem that the cell phone or battery should be changed when the card reader is changed or used in a new card recognition device. In addition, there was a problem that can not meet the needs of consumers who want to continue using the existing mobile phone. Also, there was a problem that the recognition distance did not improve much.
Therefore, in order to solve the above problems, the inventors made the invention as shown in Republic of Korea Utility Model Registration No. 335583 as shown in FIG.
The external RF card attaching apparatus attached to the third conventional portable terminal includes a base film 51 having an
However, the third conventional technology also has various problems since the RF antenna is installed to the battery part only. In the case of the conventional technologies, a metallic battery part and a ferrite core for shielding are necessary, In this case, there is a problem that two external RF cards are required because a spare battery needs to be prepared.If there is a problem that two RF cards must be replaced at the same time or a relatively expensive battery must be replaced if the RF card is to be replaced. However, there is a problem in that there is a limit in reducing the thickness.
Furthermore, if the coil is wound around the battery, deformation may occur at 67 ~ 80 degrees for PVC, which is relatively easy to work, and for PC or PET that cannot be deformed even at higher temperatures, the coil is difficult to work or coiled during winding. There was another problem such as not winding well.
The present invention is to solve the above problems, in the case of a portable terminal such as a mobile phone in recent years, with a battery attached to the cover attached to the focus on the fact that there is a gap between the cover and the battery, RF card is installed on the battery cover, but the technology to provide as thin as possible.
A portable terminal case on which the RF card is mounted according to an aspect of the present invention includes: an

On the other hand, the portable terminal case mounted with the RF card according to another aspect of the present invention, the
On the other hand, the portable terminal equipped with the RF card according to another aspect of the present invention includes a portable terminal case on which the RF card is mounted, and a portable terminal body having the
According to the present invention, since the RF card is mounted in the removable case, the area of the case is relatively larger than that of the battery, so that the number of antenna windings may be reduced, so the productivity is excellent, and the antenna may be moved out of the metallic battery part. Because it can be deployed, there is no need for ferrite cores, and the RF card can be installed in only one removable case regardless of the number of spare batteries.If you want to replace the RF card, the RF card can be installed without replacing a relatively expensive battery. It is only economical and easy to replace because it only needs to be replaced or replaced only with a new case, and it is possible to significantly reduce the thickness of the mobile phone, which absolutely affects the quality of the mobile phone. In the case of the third conventional technology, it is true that the thickness is actually about 2-3 mm, but recently, cell phone manufacturers require an RF card of about 0.45 mm for the thinner cell phone. The above-mentioned thin RF card can be mounted.

However, there may be a part that must be partially shielded. In that case, only the part should be shielded using a double-sided tape mixed with ferrite and adhesive, but this is limited to some spaces, while reducing the thickness of the entire mobile phone. There is no difficulty in maintaining the strength of the case.
For reference, the antenna coil may be considered to be in the form of a PCB, but there is a problem that the process is complicated, the price is expensive, there is a problem of environmental pollution, it is difficult to cope with the model change, and the resistance value does not come out well, In the case of the method of printing the coil, there is a problem that the process is complicated and the resistance value is not uniform. Therefore, it is preferable to wind the coil.
