Description

Multiple Card Connector {Multiple Dual Card Connector}

The present invention relates to a multi-card connector, and more particularly, to a multi-card connector that can accommodate a plurality of cards having two or more rows of terminal portions at the same time.

Recently, a mobile terminal is equipped with a smart card such as a subscriber identification module (SIM) card for subscriber identification, and includes a memory stick, a multi media card, and a secure digital card of various sizes. The back is often attached to the auxiliary memory.

A connector for simultaneously mounting a memory card together with a smart card may be a connector of the type disclosed in Japanese Patent Laid-Open No. 2005-87708 (see FIG. 1).

The conventional connector is for simultaneously mounting heterogeneous cards such as a memory card 5 having terminal portions arranged in one row and a smart card 4 having terminal portions 4 'arranged in two rows. It is possible to appropriately adjust the position of the memory card contact portion 12 on the basis of the position of the contact portion 11, and to adjust the heights of the contacts 10 and 10 'so as not to overlap each other.

On the other hand, it uses GSM (Global System for Mobile communications) method, which requires the installation of SIM card for subscriber identification. Rather, it is often used to replace the SIM card by subscribing to a mobile communication service in each country, so that the frequent detachment of the SIM card is made.

Frequent removal of the SIM card weakens the contact force of the contact making contact by elastic deformation, which causes contact failure. Therefore, it is conceivable to install a plurality of SIM cards as an improvement.

However, unlike conventional connectors that accept heterogeneous cards with different terminal positions at the same time, a card of the same size and shape having two or more rows of terminal portions is inserted, but the insertion direction of the card and the direction of the terminal with respect to the contactor are the same. Is not known to date.

In most SIM cards having a chamfer for specifying the position and the insertion direction of the terminal, it is considered that the manufacturing of the terminal in the same direction is essential for the user not to mistake the insertion direction of the SIM card.

According to the present invention, a user inserts a plurality of cards of the same size and shape having two or more terminal portions, but provides a connector manufactured with the same insertion direction of the card and the direction of the terminal with respect to the contactor.

Each of the second contacts has a second contact portion 610 for contacting the second terminal portion of the second card inserted downward, and is formed at one end of the second contact upward and connected to the circuit board on which the connector is to be installed. 2nd soldering part 620 for this is provided in the edge part opposite to a 2nd contact part, respectively.

In order for the first contact group 500 and the second contact group 600 to be installed in the upper housing 300 and the lower housing 400, one of insert molding or insert molding generally used in the connector field is used. The method may be used. Here, insert molding refers to molding with the contactors inserted into the mold of the housing, and insert molding refers to inserting the contactor into the recessed groove of the housing after the injection molding of the housing by processing concave grooves to fix the contacts into the housing. The way of fixing.

6 and 7 are two examples showing the shape of the first contact group 500 is installed in the upper housing 300, Figure 6 is that the front end of the first contact portion 510 is formed toward the inlet side into which the card is inserted 7 shows that the tip of the contact portion 510 is formed toward the opposite side of the entrance side into which the card is inserted. In FIG. 6, the portion immediately after the contact portion embedded in the housing to support the deformation of the contact portion 510 is longer than the corresponding portion of FIG. 7, so that durability can be more easily secured.

When the first contact group 500 is arranged as shown in FIG. 6, the first contact group 500 has the same structure as the cross section shown in FIG. 8 (a), and when the first contact group 500 is arranged as shown in FIG. It will have the same structure as the cross section shown.

As shown in (a) and (b) of FIG. 8, all of the first soldering portions 520 are formed at the rear of the connector so as not to interfere with the second card inserted into the lower end of the connector. In addition, although the second soldering part 620 is formed in front of the connector in FIG. 8 (a) (b), when the second contact group is formed in a form similar to that of FIG. 7, the second soldering part 620 is formed in the rear of the connector as shown in FIG. 8 (c). The first soldering part 510 and the second soldering part 520 may be formed.

The upper housing 300 includes a first lower wall portion 310 for holding the first group of contacts 500, as shown in FIGS. 3 and 8 (a); A first rear wall portion 320 in contact with the leading end of the first card; And a first sidewall portion 330 which contacts the sidewall of the first card to guide the insertion of the first card, and has an upper fastening portion 340 on the bottom surface thereof for engaging the lower housing.

Coupled with the cover fastening portion of 470, the housing fastening portion 250 of the bending bent inward from the side of the cover is coupled to the cover fastening portion of the reference numeral 450 formed concave on the side of the lower housing. Housing fasteners 270 and 272 may be bent inward to form a surface formed toward the circuit board, thereby simultaneously serving as a substrate soldering unit.

According to the fastening structure as described above, the cover 200, the upper housing 300, and the lower housing 400 are firmly coupled to form a connector, so that the assembly method is simple, thereby reducing the production time.

In addition, it may be another embodiment of the present invention to accommodate the three cards by inserting the intermediate housing between the upper housing and the lower housing as shown in FIG.

The intermediate housing 700 has the same shape as that of the first group of contacts, that is, a third contact portion 810 is upwardly formed at one end of the third contact portion, and a third solder is formed at the end opposite to the third contact portion 810. A third contact group including a plurality of third contacts having a portion 820 is installed. The intermediate housing 700 has a third lower wall portion 710 holding the third group of contacts, a third rear wall portion 720 in contact with the front end of the third card, and a side wall of the third card. A third side wall portion 730 for guiding the insertion and an intermediate fastening portion 740 for engaging the upper housing and the lower housing are provided. The third card accommodating part accommodating the third card is formed by the first lower wall part 310, the third lower wall part 710, the third rear wall part 720, and the third side wall part 730.

The rest of the configuration and the working relationship in the present embodiment will be apparent to those skilled in the art through the previous embodiment even if not described separately.
