(Technology)

The present invention relates to a card socket installation structure of a mobile communication terminal, and more particularly, in installing a card socket for mounting various cards such as a smart card and a memory card in the mobile communication terminal, the movement by installing the card socket The present invention relates to a card socket installation structure of a mobile communication terminal capable of making the mobile communication terminal slimmer by minimizing the increase in the size of the communication terminal.

(Background)

As is widely known, smart cards equipped with IC chips (smart chips) equipped with microprocessors, operating systems, security modules, and memory for storage, computing, and security functions can be used in financial, communications, education, It is widely used in almost all fields of the information and communication society, such as administration and transportation, as a means of information recording, identity verification, electronic money, credit card or electronic bank account, etc. It may also be divided into contact cards, contactless cards, and contact / contactless cards (eg combination cards).

As the field of application of mobile communication terminals including mobile phones has been expanded, smart cards and mobile communication terminals have been functionally mounted by attaching smart cards to mobile communication terminals (eg, mobile phones) rather than the traditional plastic cards. Integrating.

These smart card-equipped mobile phones are equipped with smart card, which is equipped with various authentication information, credit card information for payment, bankbook information, etc., and can be used for traffic card or credit card. It is used for the purpose of electronic banking such as withdrawal, withdrawal and check.

The integration of the smart card and the mobile communication terminal is also applied to the case where the smart card is used as the subscriber identification module to provide roaming services of the mobile communication terminal. For example, a SIM (Subscriber) may be used as the smart card as the subscriber identification module. Identity module (USIM) card, universal subscriber identity module (USIM), 0 user identity module (UIM) card, removable user identity module (RUIM) card, and the like.

On the other hand, mobile communication terminals, including mobile phones, as the functions are increasingly diversified and expanded, the required storage capacity is increasing. For example, a mobile phone equipped with a digital camera capable of capturing and storing an image requires a lot of additional memory for storing the photographed picture data in addition to the inherent storage capacity of the mobile phone.

However, embedding a large amount of memory in the main body of the mobile communication terminal for the large amount of memory required for such additional functions not only increases the price of the terminal, but also wastes the user who does not use the large capacity memory.

Therefore, in general, a memory card socket provided separately in the mobile communication terminal is not directly embedded in the mobile communication terminal, and a separate expansion memory card is selectively installed according to the user's usage pattern according to the user's use of the mobile communication terminal. To use it.

Memory cards are developed in various forms, mainly in the form of cards using flash memory, for example, Secure Digital Cards (SD Cards), Memory Sticks (MS Stick Cards), Smart Media Cards. (Smart Media Card: SMC Card), Compact Flash Card (CFC Card), Multimedia Card (Multi Media Card: MMC card), etc. are standardized.

As described above, as the functions of the mobile communication terminal are further expanded and diversified, the mobile communication terminal needs a smart card socket for attaching and detaching various smart cards and a memory card socket for attaching and detaching the memory card. The card that fits the function you require is installed in the card socket.

However, forming two different card sockets (for smart card and memory card) in the mobile communication terminal is not preferable to the design condition of the mobile communication terminal which prefers miniaturization if it performs the same function, and also reduces the manufacturing cost. There is a problem that it can be a factor to increase.

Considering the difficulty of miniaturization due to the formation of two card sockets and the increase in manufacturing cost, it may be conceivable to form only one card socket and selectively mount the smart card and the memory card. However, when the card socket is formed to be compatible with the smart card and the memory card, there is a limitation that only the smart card and the memory card can be selectively used, but not both.

As an alternative to solve this problem, the card mounting socket for mobile communication terminal of Korean Utility Model Registration No. 350772 (Registration of May 13, 2004) is proposed.

2 is a schematic diagram of a conventional cellular phone in which a card socket is installed. As shown, the mobile phone 100 is provided with a single card socket 110, the card socket 110 is formed so that two card mounting slots are stacked up and down, smart card 120 and memory card The 130 is mounted in a state where it is stacked up and down. Reference numeral 140 is a battery.

According to the structure of the conventional card mounting socket, the limited space of the mobile communication terminal is used more efficiently, thereby minimizing the size increase and the manufacturing cost increase of the mobile communication terminal by mounting two cards.

However, since the card socket of '772 shown in FIG. 2 has a structure in which two cards are stacked up and down on the substrate of the mobile communication terminal, there is a problem that may act as a factor of increasing the thickness of the mobile communication terminal.

3 is a schematic diagram of a conventional card socket installation structure applied to a mobile communication terminal. As shown, the conventional card socket installation structure 200 installs the card socket 220 on the substrate 210 of the mobile communication terminal, and mounts the memory card mounting slot and the smart card on the card socket 220. Slots are formed up and down, and the installation structure for inserting the memory card 230 and smart card 240 in each slot.

Such conventional card socket installation structure 200 has a thickness (TO) occupied by installing the card socket in the mobile communication terminal is the thickness of the substrate 210 and the thickness of the memory card 230 and smart card 240 The thickness of the sum is greater than or equal to, and therefore, at least the thickness corresponding to the sum of the thicknesses of the memory card 230 and the smart card 240 is moved to a size sufficient to accommodate the structure laminated on the substrate 210. Since the communication terminal must be designed, it may not be desirable for the slimming of the mobile communication terminal.

An object of the present invention, in installing a card socket for mounting a variety of cards, such as smart cards and memory cards in the mobile communication terminal, by minimizing the increase in size of the mobile communication terminal by installing the card socket more mobile communication terminal It is intended to be slim.

According to the present invention, there is provided a card socket installation structure of a mobile communication terminal for mounting a plurality of cards in a mobile communication terminal in the arrangement of the vertical stack.

In the card socket installation structure of the mobile communication terminal according to the present invention, a cutout portion having a size corresponding to the plane size of the card socket is formed on a substrate of the mobile communication terminal, and at least a part of the card socket is inserted into the cutout portion. And the thickness from the substrate to the upper surface of the card socket becomes thin as it corresponds to the insertion portion of the card socket to the cutout.

Hereinafter, with reference to the accompanying drawings will be described in detail the card socket installation structure of the mobile communication terminal according to the present invention. The following embodiments are merely illustrative of the card socket installation structure of the mobile communication terminal according to the present invention, and are not intended to limit the scope of the present invention.

1 is a schematic diagram of a card socket installation structure of an exemplary mobile communication terminal according to the present invention.

The card socket installation structure 1 of the mobile communication terminal according to the present invention is a card socket 20 for mounting two or more cards 2, 3 on a substrate 10 of a mobile communication terminal in a vertically stacked arrangement. It is an installation structure applied to.

In the specific example shown in Figs. 1A and 1B, two card mounting slots 21 and 22 are formed up and down in the card socket 20, and the memory card 2 is formed in the lower slot 21. An example is shown that the smart card (eg, SIM card) is inserted into the slot 22 on the upper side.

According to a feature of the present invention, the cutout portion 11 is formed on the substrate 10 of the mobile communication terminal for installing the card socket 20. The cutout portion 11 is a portion in which the substrate 10 is cut to a size corresponding to the plane size (horizontal / vertical) of the card socket 20 at the position where the card socket 20 is installed.

It is preferable to cut the cutout portion 11 so as to completely penetrate up and down as shown in FIG. 1, but it is also possible to cut to a certain depth without completely penetrating according to other conditions. The size of the cutout portion 11 corresponds to the size of the plane of the card socket 20, not only the size of the entire plane of the card socket 20 can be accommodated, but also the card socket 20 in the installation of the card socket 20. It is meant that the size corresponding to the portion where the 20 is overlapped with the substrate 10 is also included.

According to a feature of the present invention, the card socket 20 is installed with at least a portion (lower portion) inserted into the cutout portion 11.

In this way, the cutout portion 11 is installed on the substrate 10 and the cardholder 20 is installed in the cutout portion 11 so that the card socket 20 is inserted into the cutout portion 11. The thickness TT from the substrate 10 to the upper surface of the card socket 20 becomes thinner as it corresponds.

That is, the total thickness TO of the conventional card socket installation structure 100 described with reference to FIG. 2 is greater than or equal to the sum of the thickness of the memory card 130 and the thickness of the smart card. The thickness TT of the installation structure 1 of the present invention becomes thinner than the conventional thickness TO as much as the thickness of the portion inserted into the substrate 10, and thus, the thickness TT can contribute to the slimming of the mobile communication terminal.

In the illustrated embodiment, the portion of the card socket 20 having the slot 21 for the memory card is inserted into the cutout portion 11 of the substrate 10, resulting in a total thickness TT of the substrate 10. The thickness and the thickness of the smart card slot 21 is an example of only the sum of the thickness.

According to the card socket installation structure of the mobile communication terminal according to the present invention described above, the substrate and the card socket occupies as much as the portion accommodated in the cut portion by forming a cutout portion on the substrate to accommodate the portion of the thickness occupied by the card socket. Since the thickness can be reduced, an increase in the size of the mobile communication terminal can be minimized by installing a card socket for mounting a plurality of cards in a stacked structure in the mobile communication terminal, thereby making the mobile communication terminal slimmer. It works.
