Description

A subscriber identification module card cover}

The present invention relates to a device capable of detaching a SIM card from a terminal in a terminal executing a roaming service using a subscriber identification module (SIM) card. It relates to a device that can be detached.

Recently, roaming services between GSM-CDMA networks using subscriber identification module (SIM) cards have been implemented so that their telephone numbers can be used in foreign countries.

The SIM card is a chip that stores personal information of various subscribers, such as a specific ticket or phone book, and when connected to a CDMA (Code Division Multiple Access) terminal for international roaming, technical specifications of a mobile phone such as CDMA or GSM (European mobile communication method). A card that allows you to use your mobile phone freely at your phone number, regardless of location.

In order to receive the SIM card type international roaming service, the SIM card should be detachable from the terminal. The conventional SIM card detachment method uses a method of directly connecting the SIM card to a connector of the terminal. However, this method has a problem in that the thickness of the terminal itself becomes thick, and a detachable device must be provided in the SIM connector, thus requiring a large area on the PCB. Another method has been proposed in which a locking knob is provided as an injection molding and a SIM card is detached using a spring. However, this method has a problem in that the thickness of the terminal is increased because the thickness of the locking knob should be at least 0.7 mm. In another way, a SUS locking device has been proposed, but since the SUS is configured to hold only a part of the SIM card, the SIM connector should be wrapped around the SIM connector with an injection molding so that the SIM card can be stably placed. Therefore, it is not possible to mount other components in the PCB area on which the SIM card is placed, which causes a lot of space limitations.

Accordingly, the present invention has been made to solve the above problems, and provided with a cover for detaching the SIM card in the terminal to minimize the thickness of the terminal and to be stably detached, and to remove the component on the PCB It is an object of the present invention to provide a subscriber information module card detachment device that does not limit the mounting.

In order to achieve the above object, the present invention, a stopper is installed on the PCB of the terminal body, the predetermined portion is spaced apart in a stepped state to form a spaced space portion; A cover which is connected to the PCB so as to be rotatable at one side of the stopper, and covers an upper end of the SIM card, the end of which is inserted into the spaced part of the stopper and locked to form a signal connection with a connector mounted on the PCB; And it provides a subscriber information module card detachable device including a rotating shaft for connecting between the PCB and the cover.

Hereinafter, with reference to the accompanying Figures 1 to 4 will be described in detail a preferred embodiment of the present invention.

The subscriber information module card detachment apparatus according to the present invention is implemented to stably detach the SIM card while minimizing the thickness of the terminal. In this embodiment, as shown in FIG. 1, the PCB of the terminal body 1 is provided. An injection-molded product (2) installed on (marked with a symbol " 7 " in FIG. 4) and molded at all portions except the space where the SIM card 3 and the connector 4 are located; The SIM card is rotatably connected to both sides of the space part of the injection molded product 2, and an end thereof is inserted into the inner surface of the injection molded product 2 and locked to make a signal connection with the connector 4 mounted on the PCB 7. A cover 5 which covers and protects the upper part of 3); And a rotating shaft 6 connecting the injection-molded product 2 and the cover 5.

Cover 5 in the present invention is made of a stainless material.

Here, as shown in FIG. 4B, the injection molding 2 is formed to have a stopper function by forming a spaced space portion 11a by spaced apart a predetermined portion of the spaced portion in a stepped state.

The cover 5 includes a cover body 12 having a through hole 12a of a predetermined size to press in the unlocking direction as shown in FIGS. 2A to 2C; A protrusion 13 bent upward in a central portion of one side end of the cover body 12; A locking member 14 for bending upwardly at both ends of the cover body 12 so as to span the spaced space portion 2a of the injection molded product 2; An extension member (15) formed on both sides of the other end of the cover body (12) to extend by a predetermined length and having a long hole (15a) for inserting the rotation shaft (6) in the predetermined portion; And an elastic plate 16 having a predetermined inclination angle at a central portion of the other end of the cover body 12 to provide a pressing force when the cover body 12 is locked.

The working state of the present invention configured as described above will be described with reference to FIGS. 3 and 4A to 4D.

FIG. 3 shows a state when the SIM card 3 is inserted into the connector 4 on the PCB 7, and FIG. 4A shows the A-A cross section of FIG. As shown in the figure, when the SIM card 3 is positioned on the connector 4 and the cover is closed, the protrusion 13 is spaced apart from the terminal body surface, thereby preventing the cover body from being pressed.

Then, as shown in FIG. 4B, when the cover body 12 is closed while the SIM card 3 is inserted into the connector 4, the rolling member 14 is separated from the space 2a of the injection molding 2. ), The SIM card will be completely installed.

When the locking of the cover 5 is released, as shown in FIG. 4C, when the user pushes the hand into the through hole 12a of the cover body 12, the inside of the long hole 15a of the extension member 15 is pushed. The pivot shaft 6 is pushed to secure a space for lifting the cover body 12. At the same time, the inclined elastic plate 16 is pushed and the locking member 14 is separated from the spaced apart space 2a. In this state, as shown in FIG. 12) When lifted up, the SIM card (3) is in a state that can be separated.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

As described above, according to the present invention, by attaching a stainless steel cover that is detachable while being rotated to the site where the SIM card is mounted on the rear surface of the terminal body, the SIM card is easier to attach or detach than using a locking knob made of a conventional injection molding product. It can be carried out in a simple manner, and has the effect of reducing the thickness of the terminal to a minimum.

In addition, since the cover is located only in the area protecting the SIM card, it has another effect of not mounting any other components on the PCB.
