Description

FIELD OF TECHNOLOGY

This technical solution relates to the field of computer technology.

BACKGROUND

Some modern cell phones and smartphones contain two expansion slots, one of which is used for a SIM card, and the other is used either for a SIM card or a memory card (the slot is combined). The user has to choose between two SIM cards, or a SIM card and microSD memory card.

To solve the need for the simultaneous use of two SIM cards and a memory card at the same time, some users glue the MicroSD memory card and (nano) SIM card with adhesive with each other, previously reducing the thickness of the memory card and the dimensions of the SIM card with a file, knife or other tool so that the received device entered the phone slot. The disadvantage of this solution is the ability to spoil the SIM card during trimming, difficulties with removing the resulting device from the phone’s slot, device sticking in the phone’s slot, SIM card unreadable by the smartphone (phone), if the location of the contacts in relation to the slot and memory card is not observed.

ESSENCE

This technical solution is aimed at eliminating the problems existing in the prior art, provides a single product that allows for the simultaneous use of a memory card in one phone slot combined with a SIM card while maintaining operability and the possibility of replacing (removing) the product without damaging the product or phone slot.

A microSD memory card (memory card), combined with a SIM subscriber identity module (SIM module), includes:

a microSD memory card integrated with the SIM subscriber identity module, and the SIM module contacts are located at a distance of 5.6-6 mm from the memory card contacts located at the top of the memory card and 1-1.2 mm from the bottom of the memory card, the side margins are 0 -0.3 mm, while the SIM module lies to a depth of 0.2-0.35 mm from the surface of the memory card.

DESCRIPTION OF DRAWINGS

In FIG. 1 depicts one embodiment of a product in three views and in cross section. In this embodiment, the indentation of the SIM card from the bottom of the memory card is 1.2 mm, the width of the SIM card is 8 mm, the SIM card does not have side indents from the memory card. The thickness of the product in the place without the growth is 0.7 mm, in the place of the growth - 0.9 mm, in the location of the contacts of the memory card - 0.8 mm.

DETAILED DESCRIPTION

Secure Digital Memory Card (SD) - format of memory cards (flash memory) used in portable devices. Today it is widely used in digital cameras and camcorders, mobile phones, PDAs, communicators and smartphones, e-books, GPS-navigators and in some game consoles.

SIM-card (English Subscriber Identification Module - Subscriber Identity Module) - Subscriber Identity Module used in mobile communications. SIM cards are used in GSM networks.

- Full-size SIM-card (86 × 54 × 0.84 mm) - an outdated standard, used in early cell phones (the size of a bank card);

- Mini-SIM-card (25 × 15 × 0.76 mm) - is widely used in GSM-phones and in most phones with 3G, released in the 2000s and early 2010s;

- Micro-SIM (15 × 12 × 0.76 mm) - used in new models with 3G and LTE

- Nano-SIM (12.3 × 8.8 × 0.67 mm) - The following Nano-SIM size has been approved by the European Telecommunications Standards Institute (ETSI): length -12.3 mm, width - 8.8 mm, and thickness - 0.67 mm. The official Nano-SIM standard assumes full compatibility with previous versions. Essentially, the new SIM card is the same as the Micro-SIM, only with plastic edges removed.

To combine in a microSD card made using a mold, a recess is made for the SIM card chip. Next, the chip and contacts of the SIM card are soldered there. The product represents a single design.

The composition of the memory card has been moved so that the SIM card chip rises there. Then, with the components placed in their places, the card is poured, and a monolithic product with an integrated SIM card chip is obtained. Then the SIM card contacts are attached on top.

For the combined device to work correctly, it is necessary that

The permissible thickness of the product in place without a growth of 0.7 mm is 0.83 mm. In the place of the growth of 0.75 mm - 0.95 mm.

The SIM card is located in the microSD card as follows:

- from the edge from the side of the contacts the distance is 5.8 mm, while a distance of 5.6 mm - 6 mm is allowed.

- from the lower edge of 1.2 mm, while a distance of 1 mm - 1.2 mm is allowed.

- on the sides, the SIM card repeats the size of the memory card (i.e. 11 mm), while the SIM card is allowed to be indented from the side edges of the memory card by 0.1 mm - 0.3 mm.

In some implementations, instead of indenting from contacts, the size of the SIM card may be specified.

The components of the SIM card do not touch and are not connected to the electronic components of the memory card. The SIM card lies at a depth of 0.2 mm to 0.35 mm in the memory card. Depth may vary depending on the type of chip used. Within the given framework, the size can be any, without compromising performance.

In some embodiments, the thickness of a memory card with an integrated SIM card does not change, relative to the thickness of a standard microSD memory card.

Claims (1)

A microSD memory card (memory card) combined with a SIM subscriber identity module (SIM module), including a microSD memory card integrated with a SIM subscriber identity module, with the SIM module contacts located 5.6-6 mm from the memory card contacts located in the upper part of the memory card, and 1-1.2 mm from the lower edge of the memory card, the side margins are 0-0.3 mm, while the SIM module lies to a depth of 0.2-0.35 mm from the surface of the memory card.
