Socket terminal for dual card socket in mobile communication terminal {Socket Terminal for Dual Card Socket in Mobile Phone}

The present invention relates to a dual card socket for a mobile communication terminal, and more particularly, to a dual card socket installed in a mobile communication terminal so that two cards such as a smart card and a memory card can be mounted at the same time in a vertical stacking state. As a socket terminal for electrically connecting the card terminal of the card to be inserted, the dual card socket can minimize the phenomenon that the insertion and extraction of the card is not smooth due to the deformation of the socket terminal and the socket frame due to the insertion of the insertion card. It relates to a socket terminal for.

As mobile phones and mobile communication terminals become more diverse and expanded, their required storage capacity is increasing. For example, a digital camera capable of capturing and storing images or a mobile phone equipped with MP3 requires an additional memory card to store photo data or MP3 data in addition to the mobile phone's inherent storage capacity.

For this reason, mobile communication terminals have been widely marketed to include a memory card socket to selectively install and use a separate expansion memory card according to a user's preference according to a user's mobile communication terminal usage.

Also, as is widely known, smart cards equipped with IC chips (smart chips) equipped with microprocessors, operating systems, security modules, and memory for storage, arithmetic, and security functions can be used for finance, communication, and education. It is widely used in almost all fields of information and communication society such as business, administration, transportation, etc. as information recording, identity verification, electronic money, credit card or electronic billing, etc. Depending on the method, it may be classified into a contact card, a contactless card, and a contact / contactless combination card (eg, a combination card).

As the field of use 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 (e.g. mobile phones) rather than traditional plastic cards. There is a trend to be integrated.

Such a smart card-equipped mobile phone has a built-in smart card that includes information on various authentications, credit card information for payment, bankbook information, and the like, and is used as an identification module, a traffic card or a credit card. It is used for electronic bank accounts such as account inquiry, transfer, withdrawal and check.

The application of smart cards to mobile phones can be said to begin with the Subscriber Identity Module (SIM) card used as a user identification module for roaming services in European GSM mobile phones. Universal Subscriber Identity Module (USIM), User Identity Module (UIM) card, Removable User Identity Module (RUIM) card, and the like.

These identification modules are a kind of contact smart card without a contactless function. In general, these smart cards have six terminals, and thus six terminals are provided in correspondence with the card socket in which such a card is used. . Combi cards that have both contact and non-contact functions are usually provided with two additional antenna connectors for the connection of RF antennas, so they usually have eight terminals, and the corresponding card sockets have eight terminals. .

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

7 is a schematic diagram of a conventional mobile phone to which a conventional dual card socket is applied, and FIG. 8 is a schematic exploded perspective view of a conventional dual card socket to a mobile phone.

As shown in Figures 7 and 8, the dual card socket 100 mounted on the rear substrate 201 side of the mobile phone 200 overlaps the smart card 101 and the memory card 102 to form a layer up and down. Is mounted.

The dual card socket 100 is formed on one side (the upper side in the drawing) of the socket frame 110 and the socket frame 110, which is injection molded from the plastic forming the overall skeleton, and the terminal 101a of the smart card 101. The smart card socket 120 is formed on the other side (lower side in the drawing) of the socket frame 110, the smart card socket terminals 121 are formed in electrical contact with the terminals of the memory card 102 Memory card socket 130 formed with the memory card socket terminals 131 connected to the 102a, is assembled on one side (upper side in the figure) of the socket frame 110 is smart with the socket frame 110 The top cover 140 for the smart card socket forming the card socket 120, and the other side (lower side in the drawing) of the socket frame 110 is assembled with the socket frame 110 and the memory card socket 130 Including a lower cover 150 for the memory card socket forming a) It said each of the sockets 120 and 130, the smart card 101 and the memory card 102 is inserted into mounting.

In the conventional dual card socket 100, socket terminals 121 and 131 are generally manufactured by pressing a conductive metal plate such as a copper plate, and socket terminals 121 and 131 are made of plastic synthetic resin socket frame 110. In the mounting method, the socket terminals 121 and 131 are embedded in the socket frame 110 by inserts (embedded) in the process of injection molding the socket frame 110 by plastic synthetic resin, or the socket terminal of the smart card. 121 are inserts (embedded) when the socket frame 110 is ejected, but the socket terminals 131 of the memory card form grooves (not shown) corresponding to the socket frame 110 in advance, and then the socket terminals in the grooves. (Double Card Socket for Mobile Communication Terminal) in Korean Patent No. 10-0683835: Registration Notice February 16, 2007.

The conventional dual card socket 100 adopts a dual structure in which the smart card 101 and the memory card 102 are mounted in a vertical stacking manner, thereby reducing the space occupied by the dual card socket 100 in the mobile phone. It is possible to minimize the increase in the size and manufacturing cost of the mobile phone.

However, the dual card socket 100 is a boundary of the socket frame 110 that forms a boundary between the smart card socket 120 and the memory card socket 130 by repeated card insertion and the pressure of the inserted card. Since deformation occurs in the flesh portion 111, for example, to narrow the space of the socket 130 for the memory card, insertion or extraction of the memory card 102 (usually a cam mechanism is used for mounting the memory card) It may not be done well, and this problem is a problem that becomes worse as the number of times the card is installed.

That is, when the smart card is inserted, the smart card socket terminals 121 (generally six or eight) embedded in the socket frame 110 are subjected to continuous contact pressure from the smart card 101 (for example, If a load of about 100g is applied to each terminal, a load of 800g is applied to a total of eight terminals), and the inserted smart card 101 is for the smart card of the part where the socket terminal 121 for the smart card is embedded. The pressure is continuously applied to the boundary portion 111 of the socket frame 110, which forms an intermediate boundary between the socket 120 and the memory card socket 130, and thus the boundary portion 111 of the socket frame 110. Deformation that sags downward (deformation toward the direction where the card insertion space of the memory card socket becomes narrower) gradually progresses, and as a result, insertion and extraction of the memory card are not smoothly performed.

In order to prevent deformation of the boundary portion 111, the thickness of the plastic of the socket frame 110 of the corresponding portion can be made thicker to better withstand the pressure of the card, but the reinforcement of such thickness is the thickness of the dual card socket. It causes an increase, and consequently, an increase in the thickness of the mobile phone, which is not easy to apply in reality.

Another problem related to the modification of the conventional dual card socket 100 is, for example, the card terminal 102a (the smart card socket terminal in the illustrated embodiment) is the socket terminal 121: the smart card socket of the illustrated embodiment In the through hole 112 of the socket frame 110 formed to be electrically connected to the terminal), a portion of the socket terminal 121 exposed to the through hole 112 is inserted into a card (eg, a smart card) 101. When a long time passes by being pressurized, the elasticity of the socket terminal 121 is weakened, so that connection failure occurs, and the boundary part 111 acts as a cause of sagging.

That is, as shown in Fig. 9, the socket terminal 121 (socket terminal for smart card) is a structurally single member, but is functionally disposed in the through-hole 112 and electrically connected directly to the card terminal 102a. It is continuous to the part 121a, the support part 121b extended continuously to the contact part 121a, the insert part 121c inserted in the socket frame 110, and the insert part 121c continuous to the support part 121b, and the insert part 121c. Consists of a circuit connection portion 121d exposed from the socket frame 110 and electrically connected to an external circuit. When a card (eg, smart card 101) is inserted, the contact portion 121a receives continuous pressure in the direction of the arrow. When the support portion 121b sags downward, its elasticity is weakened and the boundary portion 111 of the peripheral socket frame 110 sags.

The present inventors have made various proposals to solve the above problems of the socket terminal for the conventional mobile communication terminal dual card socket.

The presenter proposed 'Dual card socket socket terminal of mobile communication terminal' of Korean Utility Model Registration Application No. 20-2007-0011221 (filed on Jul. 09, 2007). By forming an expansion-filled piece that is widely extended in the portion and embedding the expansion-filled piece in a socket frame around it, insertion of the card prevents the insertion or extraction of the card as the socket frame is deformed and the card is pressed. It solved the problem.

In addition, the 'Dual Card Socket for Mobile Communication Terminal' of Korean Utility Model Registration Application No. 20-2008-0000283 (filed on Jan. 08, 2008) of the inventors of the present invention is a socket of a first latch and a corresponding position of the cover. Deformation of the socket frame is minimized by mutual locking of the second locking holes of the frame.

In addition, the present inventors proposed a 'socket terminal for dual card socket of mobile communication terminal' of Korean Patent Application No. 10-2007-0134122 (filed Dec. 20, 2007), and this proposal forms an extension plate on the socket terminal. This ensures that the socket frame is deformed by inserting it into the socket frame as wide as possible.

In addition, the 'Dual Card Socket for Mobile Communication Terminal' of Korean Utility Model Registration Application No. 20-2008-0006820 (2008. 05. 26) of the inventors of the present invention is a socket frame that has weak structural support among the four edges of the socket frame. By inserting reinforcement pieces along one side of the reinforcement to prevent deformation of the boundary strip.

An object of the present invention is to solve the above-mentioned problems related to the dual card socket of a mobile communication terminal in which two sockets are stacked up and down, and the socket terminal is drooped under pressure by an inserted card, and its elasticity is weakened. Therefore, by preventing the border portion of the socket frame is deformed, it is to provide a socket terminal for a mobile communication terminal dual card socket that can minimize the phenomenon that the insertion and extraction of the card is not smooth.

According to the present invention, there is provided a socket terminal for a mobile communication terminal dual card socket.

The socket terminal of the first embodiment according to the present invention is formed by pressing a metal plate, and is inserted into the socket frame of the dual card socket for a mobile communication terminal, for a mobile communication terminal dual card socket electrically connected to the card terminal of the card. A socket terminal, comprising: a contact portion exposed to a through hole formed in the socket frame, and electrically connected directly to the card terminal; a support portion extending continuously across the through hole; An insert portion inserted into the socket frame, and a circuit connection portion that is continuous to the insert portion and exposed to the outside from the socket frame and electrically connected to an external circuit.

Here, the support portion is bent three or more times between the insert portion and the contact portion, and the insert portion and the contact portion are not connected in a straight line, but are connected in a bent state.

The socket terminal of the second embodiment according to the present invention, the contact portion exposed to the through-hole formed in the socket frame electrically connected directly to the card terminal, the support portion extending across the through-hole continuous to the contact portion, The support part and the contact part are formed to be cut and inserted into the socket frame, and a circuit connection part connected to the external part of the insert part and continuously exposed to the outside from the socket frame.

Here, the support portion is bent three or more times between the insert portion and the contact portion is connected between the insert portion and the contact portion in a bent state, not connected in a straight line; The insert portion is formed of an extension plate that is widely extended in a range that is not electrically shorted with another adjacent socket terminal, and is inserted into the socket frame in a large area.

Preferably, the expansion plate is formed with a through hole, and the socket frame which is injected above and below the expansion plate is vertically penetrated through the through hole to be integrally coupled.

According to the socket terminal for a mobile communication terminal dual card socket according to the present invention, the support portion connecting between the contact portion to which the card terminal is connected and the insert portion inserted into the socket frame is not a straight line, but the contact portion and the insert portion are bent. When the external force is applied to the contact portion by the insertion of the card, the support portion supports the external force more elastically. Thus, the insertion of the card weakens the elasticity of the socket terminal (that is, the support portion) and thereby the boundary of the socket frame. It can reduce the phenomenon that the deformation, and as a result can minimize the phenomenon that the insertion and extraction of the card is not smooth.

The socket terminal 1 for the dual card socket of the mobile communication terminal according to the present invention is inserted when injection molding the socket frame 4 of the dual card socket 3, similar to the socket terminal of the conventional general dual card socket. Like the copper plate, the metal plate 2 with good electrical conductivity is formed by pressing.

As described above in relation to the prior art, the number corresponding to the card terminals 5a and 6a of the cards (smart card 5 and memory card 6) inserted into the socket frame 4 of the dual card socket 3 Although the socket terminals of are provided in a predetermined number and arrangement, these socket terminals are formed by pressing or machining the metal plate 2 integrally or divided into several, as shown in Figure 6, but the socket terminal 1 of the present invention Rather than being applied to the recognition terminal 8 for electrically recognizing whether or not the memory card socket terminal 7 or the memory card M is mounted, it is suitable for application to the socket terminal 1 for the smart card. As the socket terminal 1, a socket terminal for a smart card will be described.

In addition, eight (or six) smart card socket terminals 1 applied to the socket frame 4 have four (or three) shorter lengths of the insert portions 30, 30a, and 30b. The short-terminal terminals 1A and the insert section are arranged in two rows of four (or three) long-terminal terminals 1B, which are relatively long. These short-terminal terminals 1A and the long-terminal terminals 1B are arranged in two rows. ) Has a slight difference in structure, and hereinafter, the short-socket terminal 1A will be described as a first embodiment to which the present invention is applied, and the long-socket terminal 1B will be described as a second embodiment to which the present invention is applied. Explain.

First embodiment (short socket terminal)

As shown in Figs. 1 to 3 and 6, the socket terminal 1A of this embodiment is formed of one single member, similarly to the conventional socket terminal, but functionally the contact portion 10 and the support portion ( 20), the insert part 30a and the circuit connection part 40 are comprised.

The contact portion 10 corresponds to the through hole 4a formed in the socket frame 4 in a number corresponding to the number of card terminals 5a of the inserted card 5 (smart card in the illustrated embodiment). Exposed to the sphere 4a and electrically connected to the corresponding card terminal 5a of the inserted card 5, the contact portion 10 has its end inserted for elastic connection with the card terminal 5a. Toward the card (5).

The support portion 20 is continuous to the contact portion 10 and extends across the through hole 4a. The insert portion 30a is inserted into the socket frame 4 in succession to the support portion 20. The circuit connecting portion 40 is continuous to the insert portion 30a and is exposed from the socket frame 4 to be electrically connected to an external circuit.

At this time, in order for the contact portion 10 to be elastically connected to the card terminal 5a, the contact portion 10 and the insert portion 30 form a step with different heights from each other, and the support portion 20 contacts diagonally. The part 10 and the insert part 30a are connected.

According to a feature of the present invention, the support portion 20 is not a shape that connects the insert portion 30a and the contact portion 10 in a straight line, but is bent (bended) three or more times to insert the portion 30a and the contact portion 10. ) Is connected in a bent state. That is, the support part 20 is provided with the bending part 21 of two or more steps, Preferably it is two steps.

That is, the conventional socket terminal 121 described with reference to FIG. 9 eliminates the step between the insert portion 121c and the contact portion 121a as the support portion 121b is bent up once from the insert portion 121c. In the socket terminal 1 of the present embodiment, the support portion 20 is bent upward from the insert portion 30a once, downward once, and once again upward, thereby forming two or more bent portions 21. The support portion 20 connects the insert portion 30a and the contact portion 10 in a bent state.

The position of the bent portion 21 is not particularly limited and is preferably a position structurally adjacent to the insert portion 30a, and the number of bends is not excluded four times, but structurally three or five times is preferable, and three times Most preferred.

As described above, the socket terminal 1A of the present embodiment has a support portion 20 when the pressure is applied to the contact portion 10 by inserting the smart card 5 because the support portion 20 is bent by a plurality of bendings. Since the structure of the bent portion 21 of () to support the external force more elastically, the elasticity of the support portion 20 is weakened due to the insertion of the card (5) or because of the boundary portion (4b) of the socket frame (4) ) Can be reduced, and as a result, the insertion and extraction of the card (memory card: 6) can be minimized.

2nd specific example (long-terminal socket terminal)

The second embodiment combines the configuration of the present inventors Korean Patent Application No. 10-2007-0134122 to the first embodiment.

As shown in Figs. 1, 4, 5 and 6, the socket terminal 1B (long-socket terminal) of this embodiment is also a single unit like the socket terminal (short-socket terminal: 1A) of the first embodiment. Although formed of a member, it is functionally configured to include a contact portion 10, a support portion 20, an insert portion 30b, and a circuit connecting portion 40. Hereinafter, description will be given mainly on a structure different from the first embodiment. do.

The socket terminal 1B of the second embodiment has a difference that the insert portion 30b is relatively longer than the embodiment of FIG. 1 due to the distance between the circuit connection portion 40 and the support portion 20.

The second embodiment is another configuration different from the first embodiment, the expansion plate 31 is sufficiently extended in the range that is not electrically shorted with the other socket terminal adjacent to the insert portion (30b) inserted into the socket frame (4) It is inserted into the socket frame 4 in a large area.

As the expansion plate 31 is formed in the insert portion 30b as described above, the expansion plate 31 acts as a reinforcing structure in the socket frame 4 to exert pressure applied by the smart card 5 inserted therein. Since it is properly dispersed, the phenomenon in which the boundary part 4b of the socket frame 4 is deformed by the insertion pressure of the smart card 5 can be reduced, and as a result, the insertion and extraction of the card 6 (memory card) is prevented. It can reduce the phenomenon of not being smooth.

The shape of the extension plate 31 in the socket terminal 1B of FIG. 4 is one example, and the extension plate 31 is used as a reinforcing structure in the socket frame 4 within a range not electrically shorted with another adjacent socket terminal. Naturally, it can be formed into many different shapes that can play a role and disperse the applied pressure.

In Fig. 6, the opposite faces of the two long-socket terminals 1B adjacent to the recognition terminal 8 are made into waveforms, and the intervals are larger. The socket terminal for the memory card is inserted in the socket frame 4. It is to eliminate the interference with 7).

The through hole 32 formed in the expansion plate 31 is formed of the socket frame 4 when the expansion plate 31 is inserted into the socket frame 4 and the socket frame 4 is injected above and below the expansion plate 31. (For example, plastic synthetic resin) is to be integrally coupled to meet in the through-hole (32).

The illustrated shape and arrangement of the through-holes 32 is just one example, and various shapes and arrangements may be employed as long as they can prevent the separation of the material of the socket frame 4 such as a square, a rectangle, and a comb-shaped pattern. have.

Another configuration of the second embodiment different from the first embodiment is that the support portion 20 and the contact portion 10 of the first embodiment are continuous to the insert portion 30b, but the contact portion 20 and the contact portion 20 of the second embodiment are The portion 10 is formed in the expansion plate 31 by cutting the expansion plate 31 of the insert portion 30b in an approximately C shape.

Of course, the support portion 20 of the second embodiment thus formed is bent three or more times as in the first embodiment to form the bent portion 21 between the insert portion 30 and the contact portion 10.

FIG. 6 shows an example in which eight socket terminals 1 according to the present invention are integrally formed using a single metal plate 2, and a memory card recognition terminal 8 is also formed together. The memory card socket terminal 7 applied to the memory card socket 3b widely applied to the dual card socket 3 together with the socket 3a for the production may be manufactured by pressing a separate metal plate, for example, The metal plate 2 of FIG. 6 may be formed together with the socket terminal 1 of the present invention by using an empty space.

6, the edge 2a surrounding the socket terminals 1 of the present invention is retained without being removed by metal scrap in the pressing process of manufacturing the socket terminal 1 of the present invention, and the socket terminal of the present invention ( This part is removed after inserting 1) into the socket frame 4.

As shown in FIG. 1, the upper and lower covers for the smart card forming upper and lower portions of the socket frame 4 in cooperation with the socket frame 4 to form the smart card socket 3a and the memory card socket 3b, respectively. (9) is combined.

According to the socket terminal 1 of the present invention described above, the support portion 20 is bent three or more times and connected between the insert portion 30 and the contact portion 10 in a bent state, thereby bending the support portion 20. The structure of the part 21 supports the external force more elastically, so that the elasticity of the support part 20 is weakened, or the boundary part 4b of the socket frame 4 is deformed, thereby reducing the phenomenon of the insert part. By further applying the extension plate 31 to 30b, it is possible to further reduce the deformation of the socket frame 4 by dispersing the pressure.
