Description

  The present invention is an IC card connector in which two types of cards having substantially the same length and width and different thicknesses are inserted upside down and connected to an internal contact. The present invention relates to an IC card connector in which the clearance inside the housing caused by the difference is eliminated so that two types of cards can reliably contact the contacts.

Various types of IC card connectors have been proposed in which a plurality of types of IC cards can be inserted into one IC card connector, and the type shown in FIG. 8 is one of them (Patent Document 1).
As shown in FIG. 8, the first IC card 11 and the second IC card 12 having substantially the same width and length, one kind of card having a narrow width and a long length (not shown), One that can cope with four types of width and one type (not shown) having a long length is shown.

In the case of the two types of first IC card 11 and second IC card 12 having substantially the same width and length, the first IC card 11 is thick and has step portions on both side edges. The second IC card 12 is thin. Since the first IC card 11 and the second IC card 12 have almost the same thickness, shape and arrangement of the electrodes where the electrodes are formed, the first IC card 11 When inserted into the card insertion slot 13 of the housing 10, as shown in (a-1) and (a-2), the downward electrode contacts the IC contact 15, and the second IC card 12 is inserted into the card insertion slot. When inserted while being placed on the guide step 14 inside 13, the downward electrode comes into contact with the IC contact 15 as shown in (b-1) and (b-2). The discrimination between the two types of cards is performed by a switch (not shown).
JP 2003-100369 A

Since the first IC card 11 and the second IC card 12 have almost the same thickness and the shape and arrangement of the card where the electrodes are formed, the IC contact 15 can also be used. it can. However, when the shape and arrangement of the electrodes of the two types of cards are different by using a common card insertion slot, the arrangement of the IC contacts 15 is also different, and therefore, it must be inserted upside down. However, the clearance inside the housing differs when a thin card is inserted and when a thick card is inserted.
The problem to be solved by the present invention is that when a thin card is inserted, the contact and the electrode are in contact with each other with a normal deflection amount. When a thick card is inserted, the card is inserted. The pressure is too large, and there is a risk that the contact and the electrode come into contact with an abnormally large amount of deflection, causing the contact to be deformed or broken. On the other hand, when a thick card is inserted, if the contact and the electrode are in contact with each other with a normal bending amount, the insertion pressure of the card is too small when the thin card is inserted, and the contact and the electrode May cause poor contact.

An escape hole 63 for projecting the second card contact 27 is formed in the approximate center of the top plate portion 54.

The operation of the IC card connector configured as described above will be described.
(1-1) Insertion of the second IC card 12 in a normal state (the electrode 20 is upward) IC in a state where the second IC card 12 is normal (the electrode 20 is upward and the narrow portion 21 is on the left side in the insertion direction) When inserted into the card insertion slot 36 of the card connector, the second IC card 12 is guided by the guide plate portion 57 as shown in FIG. 5A-1 and FIG. 58, the leading end 22 on the narrow width portion 21 side is inserted while being guided by the guide 60, and the leading end 22 is positioned between the first card contact 26 and the second card contact 27. At this time, since the second IC card 12 is thin, an unnecessary clearance is generated inside the IC card connector.

As shown in FIG. 1, when further inserted with the right end of the distal end portion 22 engaged with the locking portion 71 of the locking projection piece 70, the heart cam 69 integral with the locking projection piece 70 is brought into the compression spring 32. The tip of the lock pin 31 slides counterclockwise in the sliding groove 65 from the start point 67 in the figure. Since the second IC card 12 is thin and has the narrow width portion 21, the left end of the tip portion 22 does not come into contact with the contact portion 76 of the spacer 28, as shown in FIG. The distal end portion 22 rides up while rubbing the inclined surface portion 75. Since the spacer 28 is pressed by the spacer spring 29, it does not move from the original position. When the tip 22 of the second IC card 12 rides on the spacer 28, the electrode 20 is connected to the second card contact 27 with an appropriate contact pressure. When reaching the position where the second IC card 12 can be inserted, one end portion of the lock pin 31 reaches the end portion of the sliding groove 65. When the pushing force is removed, the locking slider 30 is returned by the compression spring 32. One end of the lock pin 31 is locked in the pin locking recess 66, and the inserted state of the second IC card 12 is maintained.
In this inserted state, the base end portion of the second IC card 12 is urged downward by the guide plate portion 57 with appropriate pressure in the vicinity of the card insertion hole 36.
At this time, as shown in FIG. 6A, the movable movable piece 83 of the open / close terminal 33 is pushed out at the outer edge past the narrow width portion 21 of the second IC card 12 to the contact portion 86 of the open / close terminal 34. A signal in contact with the insertion of the second IC card 12 is output.

  When removing the second IC card 12, when the second IC card 12 is pushed again, one end of the lock pin 31 comes off from the pin locking recess 66, and when the pushing force is removed, the other sliding groove 65 is formed. Returning to the original start point 67, the electrode 20 and the second card contact 27 are disconnected from each other as shown in FIG.

(1-2) Inserting the second IC card 12 in an abnormal state (the electrode 20 is turned over) IC in a state in which the second IC card 12 is abnormal (the electrode 20 is downward and the narrow portion 21 is on the right side in the insertion direction) When inserted into the card insertion slot 36 of the card connector, the second IC card 12 first passes between the position correcting portions 58 on both sides while being guided by the guide plate portion 57, but in the abnormal state of FIG. As described above, the narrow width portion 21 side passes through the position correction portion 58, the outer edge reaches the position correction portion 58, and the tip 22 on the opposite side of the narrow width portion 21 comes into contact with the guide portion 60, so No more can be inserted.

(2-1) Inserting the first IC card 11 in a normal state (the electrode 16 is downward) With the first IC card 11 in a normal state (the electrode 16 is downward and the narrow side edge 18 is upward) When inserted into the card insertion slot 36 of the IC card connector, the first IC card 11 is fitted into the erroneous insertion prevention step 37 as shown in FIGS. 5 (b-1) and 7 (b). The width side edge 18 passes between the position correction portions 58 on both sides while being guided by the guide plate portion 57, and the wide side edge 17 passes under the position correction portion 58, as shown in FIG. The right end of the tip 22 of the wide side edge 17 engages with the locking portion 72 of the locking protrusion 70. At this time, since the first IC card 11 is thick, the inside moves with an appropriate clearance.

When the first IC card 11 is further inserted in the engaged state, the heart cam 69 integrated with the locking projection piece 70 moves against the compression spring 32, and the tip of the lock pin 31 slides from the start point 67. It slides in the groove 65 counterclockwise in the figure. Since the first IC card 11 is thick and does not have the narrow width portion 21 unlike the second IC card 12, the left end of the tip portion 19 abuts against the abutment portion 76 of the spacer 28 while FIG. As shown in b-2), the spacer 28 is pushed against the spacer spring 29 while pushing the spacer 28 at the tip 19.
In this inserted state, the base end portion of the first IC card 11 is urged downward by the guide plate portion 57 with appropriate pressure in the vicinity of the card insertion hole 36.
At this time, as shown in FIG. 6B, the wide side edge 17 of the first IC card 11 spreads the contact movable piece 82 of the open / close terminal 33 and accurately positions the first IC card 11. However, when further inserted, the wide side edge portion 17 engages with the contact portion 87 of the open / close terminal 34 and causes the movable piece 85 to escape outward. In this state, the narrow side edge 18 of the first IC card 11 is in contact with the contact movable piece 83 of the opening / closing terminal 33 and the contact movable piece 83 moves slightly outward, but before the contact movable piece 83 is pushed out. The contact portion 86 has escaped further, the contact movable piece 83 does not contact the contact portion 86 of the open / close terminal 34, and no signal is output even when the first IC card 11 is inserted.
By moving the first IC card 11 together with the spacer 28, the electrode 16 is connected to the first card contact 26 with an appropriate contact pressure. When reaching the position where the first IC card 11 can be inserted, one end of the lock pin 31 reaches the end of the sliding groove 65. Therefore, when the pushing force is removed, the lock slider 30 is returned by the compression spring 32. One end of the lock pin 31 is locked in the pin locking recess 66, and the insertion state of the first IC card 11 is maintained.

When the first IC card 11 is pulled out, when the first IC card 11 is pushed again, one end of the lock pin 31 is disengaged from the pin locking recess 66, and when the pushing force is removed, the compression spring 32 causes the other slide Returning to the original start point 67 through the moving groove 65, the electrode 16 and the first card contact 26 are disconnected from each other as shown in FIG.
At the same time, the spacer 28 is returned to the original position by the spacer spring 29.

(2-2) Inserting the first IC card 11 in an abnormal state (the electrode 16 is turned over) Inserting the first IC card 11 into the card insertion port 36 of the IC card connector in an abnormal state (the electrode 16 is upward) If it tries to do so, since the wide side edge 17 and the narrow side edge 18 of the first IC card 11 are reversed, they cannot be inserted into the card insertion slot 36 having the erroneous insertion prevention step 37.
