Description

SIM card

technical field

The utility model relates to a SIM card, in particular to a multi-functional SIM card capable of providing memory expansion, non-contact induction, convenient insertion and extraction or door number expansion.

Background technique

SIM (Subscriber Identity Module) card is a kind of ICC (Integrated Circuit Card) smart card, which is currently widely used in identification cards of general GSM mobile phone systems or portable electronic devices (such as notebook computers), please refer to Figure 5 , the existing SIM card 2 mostly has a carrier 20 in the shape of a plasticized sheet, and a chip 21 is arranged on the carrier 20. The chip 21 stores the user's identification data, stored content data, etc., when the SIM card 2 is inserted Placed in a mobile phone (not shown in the figure), the terminals on the chip 21 will be in contact with the contacts in the mobile phone, and then use the antenna of the mobile phone itself to transmit data messages and send telecommunication data.

However, in the existing SIM card 2, when the chip 21 is arranged on the carrier 20, the SIM card 2 only has the function of the chip 21 itself. Since the carrier 20 only has a single chip 21, it is also limited in function. In addition, the chip 21 must be matched with the antenna of the mobile phone to transmit data. However, the frequency of the existing mobile phone antenna is no more than 900Hz, 1800Hz, 1900Hz, etc. Electronic devices with other frequencies (such as access control systems, etc.) Since it cannot be used in conjunction with the SIM card 2, the field of use of the SIM card 2 is limited because the antenna frequency cannot be supported.

In addition, along with the extensive use of digital data, such as image files, text files, etc. also make the memory space of the existing SIM card 2 stretched, so how to expand the memory capacity of the existing SIM card 2 has also become a challenge for SIM card manufacturers. To improve research and development topics.

Furthermore, when the existing SIM card 2 is plugged into or pulled out of the electronic device, since the carrier 20 itself does not have any structure that is convenient for the user to plug in and out, it is very inconvenient for the user to plug in and out the SIM card 2. If the strength or direction of pulling out the SIM card 2 is wrong, the chip 21 on the carrier 20 may be scratched, and in severe cases, the SIM card 2 cannot be used again.

Utility model content

In view of the existing problems of the above-mentioned existing SIM cards, the creator actively started research and development in order to solve the above-mentioned problems. Through continuous attempts and tests, the utility model was finally developed.

The main purpose of the utility model is to provide a multifunctional SIM card that can provide memory expansion, non-contact induction, convenient plug-in or door number expansion.

In order to achieve the purpose of the above invention, the utility model is achieved by adopting the following technical means, wherein the utility model has: a carrier, which is a plasticized sheet-like structure, an expansion part is arranged at the central position, and an antenna container is arranged at one end slot; the main chip is set on the carrier and is located on one side of the extension; the extension assembly is set on the extension portion of the carrier; the antenna component is set on the antenna accommodating groove of the carrier; wherein, the The expansion component can be a memory unit or other non-contact chips or contact chips. The antenna component is an RF antenna with a frequency of 13.5MHz and a frequency of 2.4GHz; the expansion component is a memory unit; the expansion component is a non-contact chip; the expansion component is a contact chip; the expansion part of the carrier is hollow shape, with a block on one side, and an engaging recess corresponding to the block on the expansion assembly; the expansion portion of the carrier is a recess structure, and the bottom of the recess and the carrier are integrally formed with a support piece; the expansion assembly The thickness is smaller than that of the carrier, and the total thickness of the expansion component and the supporting sheet is equal to the thickness of the carrier.

Through the above-mentioned structure, the utility model can improve the function of the SIM card itself, and the memory space, door number or other functions of the SIM card can be increased by using the expansion assembly as required, and the antenna assembly can be used for the cooperation of other frequency electronic devices, so it can Let the SIM card have more functions.

Detailed ways

Please refer to Fig. 1 and Fig. 2, the SIM card of the embodiment of the present invention has: a carrier 10, which is a plasticized sheet-like structure, an expansion part 11 is arranged in its central position, and an antenna accommodating groove 12 is arranged at one end The main chip 13 is arranged on the carrier 10 and is located on one side of the extension part 11; the extension assembly 14 is arranged on the extension part 11 of the carrier 10; Set slot 12.

The expansion assembly 14 can be a memory unit or other contactless chips or contact chips. When the expansion assembly 14 is a memory unit, the SIM card has the function of expanding memory; when the expansion assembly 14 is a contactless chip, the expansion The component 14 can be used with the antenna component 15 on the induction of the access control system, etc.; when the expansion component 14 is a contact chip, the contact chip can be used as the function of the main chip 13, so that the SIM card can store two door numbers at the same time SIM card used.

The antenna component 15 can be an RF antenna, and its frequency can be 13.5 MHz or 2.4 GHz to meet the requirements of various electronic devices.

Please refer to FIG. 3 , the expansion part 11 of the carrier 10 can be hollowed out, with a locking block 110 on one side, and an engaging recess 140 corresponding to the locking block 110 is provided on the expansion assembly 14, so that the expansion assembly When 14 is disposed on the extension part 11 , the positioning effect can be achieved through the combination of the locking block 110 and the engaging recess 140 .
