The first card 10 and the second card 20 may belong to the same category, for example, they may all be micro SIM cards. Of course, as long as they are the same type of card, other types of cards can be applied in addition to the microSIM card.

Although in the preferred embodiment of the present invention, the first card 10 and the second card 20 can be inserted and fixed from the same direction, but are not limited thereto, the two cards 10 and 20 can be inserted and fixed from different directions from each other. .

The dual card type socket 100 for a terminal according to a preferred embodiment of the present invention may include a first housing 110, a second housing 120, and a first cover 130.

The first card 10 is mounted on the first housing 110, and has a plurality of first connection terminals 140 connected to the first card 10, and is fixed to the upper surface of the printed circuit board 30.

The second card 120 is mounted on the second housing 120, and has a plurality of second connection terminals 150 connected to the second card 20, and is fixed on the printed circuit board 30 while covering the first card 10 and the first housing 110. . The first connection terminal 140 and the second connection terminal 150 are arranged in the same shape.

The first cover 130 is fixed to the second housing 120 to cover the second card 20. The first cover 130 is made of a metal material to protect the second card 20 from external impact.

In the dual card type socket 100 for a terminal according to the present invention, two connectors are mounted on the printed circuit board 30 as a laminated connector to realize its function.

In addition, the second housing 120 is positioned at a rearward position relative to the first housing 110 such that the first housing 110 and the second housing 120 are disposed in a stepped manner as a whole. Therefore, the first card 10 and the second card 20 are also inserted in a stepwise manner, that is, the second card 20 is inserted in a position rearward relative to the first card 10. Since the first card 10 and the second card 20 are inserted in a stepwise manner as described above, the first card 10 can be easily inserted and withdrawn without being restricted by the second card 20.

4 is a schematic view showing a state of a first casing fixed to a printed circuit board; and FIG. 5 is a plan view showing a state in which the first card is mounted in the first casing.

The first housing 110 is formed of an insulating synthetic resin material, and the first connection terminal 140 is formed of a metal material capable of transmitting signals. A plurality of first terminal exposure holes 111 are formed in the first casing 110 such that the first connection terminals 140 can be exposed to the outside, and the connection portion connected to the first card 10 can protrude upward. The first terminal exposure hole 111 is formed to correspond to the contact of the first card 10.

The first housing 110 has a first lead terminal 141 for connecting the first connection terminal 140 with the circuit pattern of the printed circuit board 30 to enable a transmission signal to be transmitted between the first connection terminal 140 and the printed circuit The circuit pattern of the board 30 is performed between. The ends of the plurality of first lead terminals 141 protrude outward from the both side edges and the rear end edge of the first housing 110, respectively, and are soldered to the circuit pattern of the printed circuit board 30. Here, although the first connection terminal 140 and the first lead terminal 141 may be manufactured as one body, the invention is not limited thereto. First connection terminal and first lead The two terminals of the wire terminal can be separately manufactured and then connected to each other.

The first housing 110 includes a first connecting portion 160; the first connecting portion 160 is made of a metal material and is soldered to the printed circuit board 30 to securely fix the first housing 110. The first connection portion 160 is buried in the first housing 110, and similar to the first lead terminal 141, the end of the first connection portion 160 protrudes from the edge of the first housing 110 and is subsequently soldered to the printed circuit The circuit pattern of the board 30 is on.

In the first housing 110, the first connection terminal 140, the first lead terminal 141, and the first connection portion 160 are first formed of a metal material, and then the first housing 110 is formed by overmolding using a synthetic resin material. Thereby, the first housing 110, the first connection terminal 140, the first lead terminal 141, and the first connection portion 160 are formed integrally. Therefore, the first connection terminal 140, the first lead terminal 141, and a portion of the first connection portion 160 are respectively buried in the first housing 110.

In addition, as shown in FIG. 5, on the first casing 110, the welding regions A, B, and C are all located outside the region where the first card 10 is mounted. That is, the end of the first lead terminal 141 and the end of the first connecting portion 160 are soldered to the outside of the mounting region of the first card 10 in a state where the first card 10 is mounted on the first housing 110. On the circuit pattern of the printed circuit board 30.

In this manner, since the welded portion (region) of the printed circuit board 30 does not overlap with the position of the first card 10, it is possible to prevent the risk of short-circuit or misconnection occurring when the first card 10 and the circuit pattern soldering portion overlap each other.

In fact, in the case of using a micro SIM card, the card The area is relatively small, so there is a circuit pattern below the entire bottom surface of the card. Therefore, small errors in soldering can cause solder or lead bumps to come into contact with the circuit pattern of the card, which causes a significant increase in the short circuit or misconnection of the circuit pattern. However, if the soldering region is provided in the above-described manner, there is no fear that the solder or the lead bumps may come into contact with the circuit pattern of the memory card during soldering, and thus it is possible to prevent the short circuit of the circuit pattern and the occurrence of erroneous contact (misconnection). .

Figure 6 is a schematic view showing a second housing; Figure 7 is a schematic view showing a first cover; Figure 8 is a schematic view showing a second housing fixed to a printed circuit board; Figure 9 is fixed to printing A schematic view of a second housing on a circuit board.

A first insertion space 170 for inserting the first card 10 is formed below the second housing 120, and a second insertion space 180 for inserting the second card 20 is formed above the second housing 120. That is, a first insertion space 170 is formed between the first housing 110 and the second housing 120, and a second insertion space 180 is formed between the second housing 120 and the first cover 130.

The second housing 120 may include: a horizontal plate 121 that is integrally embedded with the second connection terminal 150; a plurality of lower side walls 122, each of which is vertically formed downward from both sides of the horizontal plate 121, and The bottom surface of the horizontal plate 121 together forms a first insertion space 170 and prevents the first card 10 from being detached sideways; and a plurality of upper side walls 123 each of which is vertically formed upward from both sides of the horizontal plate 121, and The second insertion space 180 is formed together with the upper surface of the horizontal plate 121, and the second card 20 is prevented from being detached sideways.

A plurality of second terminal exposure holes are formed in the horizontal plate 121 121a, the second connection terminal 150 can be exposed to the outside, and the end of the second connection terminal 150 that is in contact with the second card 20 protrudes upward. The second terminal exposure hole 121a is formed to correspond to the contact of the second card 20.

On the rear end portion of the upper side wall 123 constituting the first housing 110, a second stopper portion 126 is integrally formed; the second stopper portion 126 is formed to be obliquely protruded inwardly so that the second card is inserted At 20 o'clock, the second card is restrained from pushing backwards. Since the first stopper portion 125 prevents the first card 10 from being unnecessarily inserted too deeply, the connection state between the first card 10 and the first connection terminal 140 can be stably maintained. Further, since the second stopper portion 126 prevents the second card 20 from being unnecessarily inserted too deeply, the connection state between the second card 20 and the second connection terminal 150 can be stably maintained.

In addition, due to the inclination of the second stopper portion 126 and the second card 20 The face is inclined correspondingly, so that when the second card 20 is inserted in reverse (reversed), the second card 20 and the second stopper 126 do not match, so that the second card 20 cannot be normally inserted. Therefore, the user can easily recognize the reverse insertion of the second card 20.

The second housing 120 includes a second lead terminal 151 for connecting the second connection terminal 150 with the circuit pattern of the printed circuit board 30 to the circuit pattern of the second connection terminal 150 and the printed circuit board 30. The signal is transmitted between. The end of the second lead terminal 151 protrudes outward from both side edges of the second housing 120, and is then soldered to the circuit pattern of the printed circuit board 30. Here, although the second connection terminal 150 and the second lead terminal 151 may be integrally formed using the same material, the present invention is not limited thereto. The second connection terminal 150 and the second lead terminal 151 may also be formed separately and then connected to each other.

The first cover 130 is composed of a shutter 131 and a pair of joint portions 132; the shutter 131 is for shielding the second insertion space 180 formed at the upper portion of the second casing 120; the pair of joint portions 132 are from both sides of the shutter 131 It is bent vertically downward and joined to both side faces of the second housing 120.

The front end portion of the shutter 131 is formed in an open shape, whereby when the first cover 130 and the second housing 120 are coupled, the front end portion of the shutter 131 can be exposed upward, and the second card 20 can be easily removed from the second card 20 The insertion space 180 is taken out. The front end portion of the opening of the shutter 131 is rounded.

The coupling portion 132 is formed with a locking hole 132a; the locking hole 132a is inserted by a fixing protrusion 124 formed on each side surface of the second housing 120, thereby achieving locking. The front end portions of the joint portions 132 are respectively formed with cards The support portions 132b; these card support portions 132b are curved in a horizontal direction facing each other, and support the second card 20. Each of the card support portions 132b is inserted into the support portion mounting hole 121b formed on the horizontal plate 121 of the second casing 120, and then mounted on the support portion mounting hole 121b.

The rear end portion of one of the pair of coupling portions 132 is formed with an insertion restricting portion 132c; the insertion restricting portion 132c is inclined corresponding to the inclined surface of the second stopper portion 126 to be in contact with the inclined surface, thereby restricting the second The insertion of the card 20.

Further, a second connecting portion 132d is integrally formed in the vertical direction on the front end portion of each joint portion 132; the second connecting portion 132d vertically penetrates the printed circuit board 30 for welding. Similarly, a third connecting portion 132e is formed on the rear end portion of each of the joint portions 132; the third connecting portion 132e is horizontally bent in the outer direction and is in contact with the upper surface of the printed circuit board 30 for soldering.

Further, similarly to the first lead terminal 141 and the first connecting portion 160, the second lead terminal 151, the second connecting portion 132d, and the third connecting portion 132e are also outside the mounting area of the first card 10 and the second card 20 Since soldering is performed, even if solder or leads are protruded during soldering, there is no fear of contact with the circuit pattern of the card, and it is possible to prevent occurrence of short circuit or misconnection of the circuit pattern.

FIG. 10 is a schematic view showing a state in which only the first card is mounted; and FIG. 11 is a schematic view showing a state in which only the second card is mounted.

The first card 10 and the second card 20 can be simultaneously installed in the dual card type socket 100 for a terminal of the present invention, or can be selectively One of the cards is installed and used. Therefore, the card can be mounted in various ways, thereby expanding the selectivity of the dual-card type socket 100 for the terminal.

Fig. 12 is a schematic view showing a side surface of a second card which is manually pressed in order to pull out the second card in Fig. 11.

In the case where the first card 10 is not inserted in the first insertion space 170, and only the second card 20 is inserted in the second insertion space 180, if pressure is applied by hand in order to pull out the second card 20, there is a second The horizontal plate 121 of the housing 120 may be bent downward to risk breakage.

This danger can be eliminated by enabling the card support portion 132b formed on each of the joint portions 132 of the first cover 130 to support the second card 20 below the entrance of the second insertion space 180. That is, in the case where the second card 20 is pressed by hand in order to pull out the second card 20, since the pressure is transmitted to the card supporting portion 132b through the second card 20, there is no The horizontal plate 121 of the second casing 120 is bent downward to be broken.

Fig. 13 is a schematic view showing that the front end portion of the second casing includes a strength reinforcing portion.

During the insertion of the first card 10 and the second card 20, one or both of the first card 10 and the second card 20 may not be properly inserted into the respective insertion spaces 170, 180, respectively. In this case, if an error occurs in the case where the respective cards 10, 20 are not correctly inserted, the front ends of the horizontal plates 121 constituting the second casing 120 are in contact with the cards 10, 20, respectively, and are subjected to an impact. This repeated impact causes the horizontal plate 121 formed in the form of a thin plate to be broken.

Therefore, at the front end portion of the horizontal plate 121 (insertion of the insertion space) The mouth side is provided with a strength reinforcing portion 152; the strength reinforcing portion 152 extends in the horizontal (left and right) direction and is made of a material having a strength higher than that of the horizontal plate 121, thereby preventing the horizontal plate 121 from being caused by repeated impacts. Broken.

In a preferred embodiment of the present invention, the strength reinforcing portion 152 is integrally formed with the second connection terminal 150. Of course, the strength reinforcing portion 152 may be formed separately from the second connection terminal 150, or may be made of a material different from the material of the second connection terminal 150.

The strength reinforcing portion 152 is inclined from the front end portion to the rear end portion of each of the upper surface and the lower surface. Therefore, when the first card 10 and the second card 20 are respectively inserted into the insertion space 170 and the insertion space 180, the respective cards 10, 20 can be slid into the insertion spaces 170, 180 along the inclined faces, respectively, thereby realizing the card 10 , 20 smoothly inserted.

Fig. 14 is a bottom view showing a state in which the first card is inserted between the first casing and the second casing; and Fig. 15 is a view showing a state in which the first casing in Fig. 14 is removed.

On the rear end portion of the bottom surface of the horizontal plate 121 constituting the second casing 120, a first stopper portion 125 is formed; the first stopper portion 125 is formed to prevent the first card 10 from being pushed rearward when being inserted. The first stopper portion 125 may be integrally formed of the same material as the second connection terminal 150 or may be formed of a material different from the second connection terminal 150. The first stopper 125 can prevent the first card 10 from being unnecessarily inserted too much. Therefore, the connection state between the first card 10 and the first connection terminal 140 can be stably maintained.

In addition, due to the inclination of the first stop portion 125 and the first card 10 The face is inclined correspondingly, so that when the first card 10 is inserted in the reverse direction, the first card 10 and the first stopper 125 do not coincide. In this case, the first card 10 cannot be inserted normally. Therefore, the user can easily recognize the case of the reverse insertion of the first card 10.

Next, an example in which the constituent elements of the dual-card type socket for a terminal device of the present invention are used as a single product will be described. 4 is a schematic view showing a first case fixed to a printed circuit board; FIG. 16 is a schematic view showing an example of using the first case formed in a socket form; FIG. 17 is a view showing use in parallel A schematic view of an example of a second housing and a first cover formed.
