DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for an IC card into which an IC card having a built-in memory is inserted and which is electrically connected to the IC card for writing or reading predetermined data to or from the memory. More specifically, the present invention relates to an IC card connector that determines the insertion posture of an IC card or the type of an IC card based on a cutout portion of the IC card.

[0002]

2. Description of the Related Art As a conventional IC card connector electrically connected to an IC card, as shown in FIG. 14, both sides 101a of an insulating case 101 are erected to form a U-shaped cross section. Card connector 100 as a card insertion path 102 into which IC card 110 is inserted
It has been known. A large number of conductive contacts 103 are attached to the insulating case 101 at an equal pitch in parallel with each other so that the contact portions are exposed in the card insertion path 102. Further, an opening surface above the card insertion path 102 is covered by a metal cover 104 provided between both side parts 101a, 101a.

When the IC card 110 is inserted into the card insertion path 102 as shown in FIG.
And a plurality of electrode portions 111 of the IC card 110 are electrically connected to the corresponding conductive contacts 103 respectively.

[0004] On one side 101a of the insulating case 101, a concave groove 113 for accommodating a stopper piece 112 made of a band-shaped metal plate is formed. The stopper piece 112 has a pivot whose base end is in the concave groove 113. It is folded back around the support pin 114 and is rotatably supported by the insulating case 101 about the base end. As shown in FIG. 16, the stopper piece 112 is attached clockwise by a torsion spring 115 disposed between the stopper piece 112 and the inner surface of the concave groove 113 in a state where no external force acts on the stopper piece 112. Urged so that its tip projects into the card insertion path 102.

[0005] By attaching the stopper piece 112 in this manner, the IC card 110 can be removed only when the IC card 110 whose portion corresponding to the projecting position of the tip end of the stopper piece 112 is cut out by the taper 110b is inserted. Insertion into the insertion path 102 is possible, and electrical connection between the electrode section 111 and the conductive contact 103 is enabled.

That is, as shown in FIGS. 16A and 16B, the taper 1

When inserted into the inside, the taper 110b abuts on the tip of the stopper piece 112, and the stopper piece 112 is
The IC card 110 can be inserted up to the position shown in FIG.

On the other hand, when the user tries to insert the IC card 120 which does not have a taper at the corresponding portion, the front end of the IC card 120 comes into contact with the tip of the stopper piece 112 as shown in FIG. Insertion is regulated.

Accordingly, the IC card 110 inserted with the electrode portion 111 in a position facing the conductive contact 103 side.
IC card 110 that can be inserted only and is upside down
Also, it is possible to prevent erroneous insertion of another type of IC card 120 in which the corresponding portion is not tapered.

[0009]

[Problems to be solved by the invention]

However, the conventional IC card connector 100 is provided with a torsion spring 11 to prevent erroneous insertion.
5. It is necessary to use another part such as the stopper piece 112, and the structure is complicated.

Further, a concave groove 113 for accommodating these parts is provided.
Is formed in the insulating case 101, the width of the insulating case becomes large, and when mounting on a printed circuit board,
The mounting area has increased, which has been an obstacle to high-density mounting.

Further, since the mounting position of the stopper piece 112 is limited to one of the both sides 101a of the insulating case 101, the position of the taper 110b of the IC card 110 is also
It is limited to a position on either side of the front end. That is, since it is not possible to make a determination by providing a notch at the center, it is not possible to insert only one type of IC card from many types of IC cards.

Further, the cutout of the IC card is also limited to a tapered shape, and there is a limitation in the design of the IC card.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide an IC card connector capable of preventing erroneous insertion of an IC card with a simple configuration without increasing the number of parts. And

It is another object of the present invention to provide an IC card connector which can prevent an erroneous insertion of an IC card without increasing the size of the entire connector.

Still another object of the present invention is to provide an IC card connector that can be electrically connected to only one type of IC card from among various types of IC cards.

[0017]

According to a first aspect of the present invention, there is provided an IC card connector including an insulating case having a card insertion path, an input / output section fixed to the insulating case and facing the card insertion path. An IC card connector in which an input / output connection portion comes into contact with an IC card inserted into a path to connect the IC card to the IC card, and a stopper plate having a free end formed into two branches is directly or indirectly connected to an insulating case. Holding and supporting the actuator,
An inclined portion is formed to be inclined inward of the card insertion path along the insertion direction of the C card, and the inclined portion is protruded into the card insertion path, and the tip of the other forked stopper piece is inserted into the card insertion path. To protrude to the position aligned with the slope,
When an IC card with a cutout corresponding to the projecting position of the tip of the stopper piece is inserted into the card insertion path, the IC card comes into contact with the inclined portion first, and the stopper piece and the actuator piece are inserted into the card. It is characterized by being evacuated from the route.

When an IC card having a cutout at a position corresponding to the projecting position of the tip end of the stopper piece is inserted into the insertion path, the IC card comes into contact with the inclined portion of the actuator piece first, and the actuator piece is inserted into the card insertion path. Evacuate from. At this time, the front end of the stopper piece does not come into contact with the IC card because the corresponding portion is cut off. When the actuator piece retreats from the card insertion path, the entire cantilevered stopper plate rotates in the direction to retreat from the card insertion path, and the tip end of the stopper piece also retreats from the card insertion path. Therefore, the IC card can be inserted to the predetermined connection position without interfering with the stopper piece and connected to the input / output connection portion.

On the other hand, when an IC card with an inverted insertion posture or an IC card of a different type, which is not cut off at a portion corresponding to the projecting position of the tip end of the stopper piece, is inserted into the insertion path, When the card comes into contact with the inclined portion of the actuator piece, the card also comes into contact with the tip end of the stopper piece protruding at a position aligned in the insertion path. Therefore, the insertion of these IC cards is restricted by the tip of the stopper piece, and erroneous connection with the input / output connection part can be prevented.

According to a second aspect of the present invention, the IC card connector is attached to the insulating case having a U-shaped cross section so that a card insertion path is formed, and the insulating case so as to cover the opening surface having the U-shaped cross section. The stopper plate is formed by cutting and raising the stopper plate integrally from the metal cover, and the actuator piece and the stopper piece are projected into the card insertion path.

In the IC card connector according to the second aspect, since the opening surface of the insulating case having a U-shaped cross section is covered with the metal cover, the insulating case can be easily molded without using a slide mold or the like. Further, since the metal cover is used, a predetermined strength can be maintained while reducing the thickness of the entire connector. Since the stopper plate is formed by being cut and raised integrally from the metal cover, there is no need to prepare the stopper plate as a separate part, and further, since the stopper plate can be formed in the thick portion of the metal cover, the entire connector does not increase in size. .

In the IC card connector according to the third aspect, the protruding position of the leading end of the stopper piece into the card insertion path may be:
It is a position corresponding to a part where a taper is formed on one side of the front end of the IC card.

According to a third aspect of the present invention, in order to prevent erroneous insertion into a conventional IC card connector, an IC card having a tapered notch on one side of a front end is similarly prevented from being erroneously inserted. Meanwhile, it can be inserted into the card insertion path and connected to the input / output connection unit.

[0024]

Embodiments of the present invention will be described below in detail with reference to the drawings. The IC card connector according to the embodiment of the present invention is a smart media connector (Smart Media Connect) mounted on a printed wiring board of a so-called digital camera.

Are provided with a plurality of conductive contacts 5 serving as input / output connection portions.

As shown in FIG. 4, the insulating case 2 is formed in a substantially flat plate shape by molding in a mold, and the main body 6 and the side portions 7, 7 standing upright on both sides of the main body 6.
The vertical section has a U-shaped section. By forming a U-shaped cross section, the inside thereof is used as the card insertion path 8.

A guide frame 9 for guiding the IC card 10 to the card insertion path 8 is formed integrally with the main body 6 and the side parts 7 on the front side as viewed from the IC card insertion side in FIG. I have.

Numerals 11, 11,... Are contact mounting grooves, which are recessed at equal intervals from each other on the main body 6 from the rear surface (the upper surface in FIG. 4A) of the insulating case 2 toward the front surface. I have. Contact mounting groove 11, 11
The length is alternately different for each one, whereby two types of contacts 5 having different lengths and different contact positions with the electrode portions 12 of the IC card 10 are arranged (FIG. 10 ( a)).

The contact 5 is formed by stamping a phosphor bronze plate into an elongated strip shape and then bending the same. As shown in FIG. 3, the contact 5 is press-fitted into a contact mounting groove 11 to be attached to the insulating case 3. The contact portion 5a on the free end side faces the card insertion path 8 on the main body 6, and the contact leg portion 5b on the other end is led out from the back surface of the insulating case 2. The contact leg 5b is connected by soldering the IC card connector 1 to a land pattern (not shown) on the printed wiring board 13, and is electrically connected to a corresponding pattern on the printed wiring board 13.

The opening surface of the card insertion path 8 having a U-shaped cross section is covered with a metal cover 3 that covers the upper surface of the insulating case 2. The metal cover 3 has side pieces 3 a on both sides thereof bent downward along the side portions 7, 7 of the insulating case 2, and engaging projections 14, 14 projecting from the side portions 7, 7 are provided with engaging holes. 15 and 15 are engaged so that the insulating case 2
(See FIG. 3). By covering the upper surface of the insulating case 2 with the metal cover 3, the card insertion path 8 can be formed in a U-shaped cross section, and the molding of the insulating case 2 becomes easy without using a slide die. Furthermore, compared to the case where the upper part of the card insertion path 8 is covered with the insulating case 2, the entire IC card connector 1 can be made thinner, and even if the thickness is made thinner, a predetermined strength against external force can be maintained.

A part of each of the side pieces 3a, 3a is formed into a leg 3b, 3b which is cut and raised and then bent horizontally, and the leg 3b, 3b is connected to an unillustrated ground of the printed wiring board 13. Soldered to the pattern. By soldering the metal cover 3 and the pattern of the printed wiring board 13, the IC card connector 1 is more firmly fixed on the printed wiring board 13, and the IC card 10
Is inserted and a moment in the rotational direction is applied to the IC card connector 1, the soldered portion of the contact leg 5b does not peel off. Further, since the metal cover 3 is electrically connected to the ground pattern, the inside of the card insertion path 8 is electromagnetically shielded.

When fixed to the insulating case 2, the upper surface 3 c of the metal cover 3 facing the card insertion path 8, as shown in FIGS. 5 and 6, protrudes in the direction of the card insertion path 8. Ribs 16 are formed. The rib 16 supports the metal cover 3 in parallel with the main body 6 of the insulating case 2 at a predetermined interval and, when the IC card 10 is inserted into the card insertion path 8, contacts the upper surface thereof.
The electrode portion 12 of the C card 10 is elastically contacted with each of the contacts 5, 5,... With a uniform contact pressure (FIG. 10).
(A)).

Further, as shown in FIG. 7, a stopper plate 20 is integrally cut and raised from the metal cover 3. The stopper plate 20 is cantilevered by the metal cover 3 when the base end 20a is integrally continuous with the metal cover 3, and has a fork-like shape when the free end side 20b bifurcates. One of the two forks is an elongated plate-shaped actuator piece 21, the tip of which is bent in a V-shape toward the inside of the card insertion path 8. When the metal cover 3 is attached to the insulating case 2, the stopper plate 20 moves from the rear side to the front side to the free end side 2.
0b is formed in the metal cover 3 so as to face (from the upper side to the lower side in FIG. 1), the front inclined portion 21a bent in a V-shape is inserted in the insertion direction of the IC card 10 (from the front side). (In the direction of the rear side) toward the inside of the card insertion path 8. Further, as shown in FIG. 6, since the entire stopper plate 20 is gently bent toward the inside of the card insertion path 8 along the longitudinal direction, the inclined portion 21a is in a free state where no external force acts. , Protrudes into the card insertion path 8 from the upper surface 3c.

The other of the two forks is an elongated plate-shaped stopper piece 22 whose tip portion 22a is slightly bent toward the inside of the card insertion path 8. The stopper piece 22
Stopper plate 2 parallel to actuator piece 21
Since the entirety 0 is bent toward the inside of the card insertion path 8, like the actuator piece 21, the distal end portion 22 a protrudes into the card insertion path 8 in a free state.

The inclined part 21a and the tip part 22a are located substantially side by side as shown in FIG.
The projections protrude at positions in the card insertion path 8 having substantially the same depth from the front.

The SSFDC 10 shown in FIG. 12 is connected to the IC card connector 1 thus configured. FIG. 12 shows the back surface of the SSFDC 10, and a plurality of electrode parts 12, 12,...
However, they are exposed in parallel in two steps. Each electrode part 1
The arrangement of 2, 12,... Corresponds to the contact portion 5 of the contact 5 described above.
a corresponds to a position protruding into the card insertion path 8, and when the SSFDC 10 is completely inserted into the card insertion path 8, each electrode portion 12, 12,... comes into contact with the corresponding contact 5. ing.

The SSFDC 10 includes a SSFDC 10a operating at 3.3V power supply voltage shown in FIG. 3A and a SSFDC 10b operating at 5V power supply voltage shown in FIG.
There are various types of IC cards, and a tapered notch 26 is formed on the left and right sides of the front end so as to identify each other and prevent erroneous insertion into another IC card connector. The IC card connector 1 according to the present embodiment is a connector to be connected to the SSFDC 10a shown in FIG.
In order to allow only the DC 10a to be inserted, the stopper plate 20 is cut out at the left position in FIG. 1 so that the distal end 22a of the stopper piece 22 is located within the card insertion path 8 and the taper 26 of the SSFDC 10a is It protrudes into the insertion path that passes.

FIG. 8 shows a case where the SSFDC 10a as an IC card is inserted into the IC card connector 1.
This will be described with reference to FIG.

FIG. 8 shows a state in which the SSFDC 10a is inserted into the IC card connector 1 and first contacts the stopper plate 20, and FIG. 9 shows a state in which the SSFDC 10a is further inserted and the stopper plate 20 is pushed up. 10 shows a state in which the SSFDC 10a is completely inserted into the card insertion path 8, respectively. In each of these drawings, FIG.
And (b) is a plan view of an essential part.

As shown in FIG. 8B, the SSFDC10
When a is inserted, the taper 26 first comes into contact with the inclined portion 21 a of the actuator piece 21. At this time, the tip end 22a of the stopper piece 22 that projects at a position aligned with the inclined portion 21a does not contact the front end of the SSFDC 10a.

As shown in FIG.
When the front end of the SSFDC 10a abuts on the inclined portion 21a, the SSFDC 10a is pushed out in a direction to withdraw from the card insertion path 8 (upward in FIG. 7A). When the actuator piece 21 is displaced in the retreating direction, the entire stopper plate 20 rotates about the base end 20a, and the stopper piece 22 also rotates in the same direction. Therefore, the distal end portion 22a of the stopper piece 22 is retracted from the card insertion path 8, and the SSFDC 10a can be inserted to the contact position with the contact 5 in the card insertion path 8 as shown in FIG. In this state, the contact portion 5a of each contact 5
Are in elastic contact with the corresponding electrode portions 12 of the SSFDC 10a and are electrically connected.

On the other hand, the SSFDC10 operating at 5V power supply voltage
The case where b is to be inserted into the IC card connector 1 will be described with reference to FIG. FIG. 3A is a longitudinal sectional view along the actuator piece 21, and FIG.

In the SSFDC 10b, the SSFDC 10a
And the taper 26 is formed at the symmetrical part,
Notches are not formed in the portions where the stopper plate 20 protrudes. Therefore, as shown in FIG.
When the SFDC 10b is inserted into the card insertion path 8, it comes into contact with the tip end 22a of the stopper piece 22 and cannot be further inserted from the contact position.
No contact.

As described above, the IC card connector 1 is
By restricting the insertion of a different type of IC card 1, erroneous insertion and erroneous connection can be prevented, but the corresponding IC card 10 (SSFDC 10a in the present embodiment) is used.
Even if it is attempted to insert it upside down, the wrong insertion can be prevented. That is, in the case of reverse insertion, the notch position of the taper 26 is apparently
b, and cannot be inserted by abutting on the tip end portion 22a of the stopper piece 22 as described above.

In the above embodiment, the IC card 10
The case where the notch is the taper 26 has been described, but the shape of the notch of the IC card 10 may be another shape.

FIG. 13 is a plan view of a principal part showing a state where an IC card 40 having a rectangular cutout is inserted into the IC card connector 30 according to the second embodiment of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals.

Assuming that the IC card 40 shown in the drawing is to be inserted, the stopper plate 20 is cut and raised in the IC card connector 30 at the position of the metal cover 3 corresponding to the rectangular cutout 31 forming portion. That is, the projecting position of the tip end portion 22a of the stopper piece 22 into the card insertion path 8 is the position where the rectangular cutout 31 at the front end of the IC card 40 passes, and the card insertion path of the inclined part 21a of the actuator piece 21. The protruding position into 8 is a position deviated from the position where the rectangular cutout 31 passes.

When the IC card 40 is inserted into the card insertion path 8, the front end of the IC card 40
Abuts on the inclined portion 21a of the actuator piece 21 before the tip portion 22a of the actuator piece 21. Therefore, as in the first embodiment, the distal end portion 22a of the stopper piece 22 is retracted from the card insertion path 8, and the IC card 40 can be inserted to a predetermined connection position. On the other hand, since the front end of the IC card in which the rectangular notch is formed at another position is in contact with the front end portion 22a of the stopper piece 22, insertion to the connection position is restricted.

According to the second embodiment, only one corresponding IC card 40 can be inserted from a plurality of IC cards in which the notch 31 is formed at any one of the front ends. Can be.

In the above embodiment, the IC card connector into which the IC cards 10 and 40 having the tapered and rectangular cutouts are inserted has been described.
Whatever the shape of the IC card is, if the cutaway shape is such that at least the inclined portion 21a of the actuator piece 21 comes into contact with the front end of the IC card before the tip end 22a of the stopper piece 22, It can be determined and inserted.

In the above embodiment, the stopper plate is formed integrally with the metal cover. However, as long as the stopper plate has elasticity, the stopper plate may be formed using other materials such as synthetic resin and synthetic rubber. Good.

Further, in the above embodiment, the IC card has been described as a card having a built-in memory.
Even if it has a built-in interface circuit or other electronic circuit, or has only a predetermined short-circuit electrode portion to form a switch circuit in contact with a contact on the IC card connector side, Good.

The IC card may be a magnetic card such as an ID card to which a magnetic tape is adhered. When the IC card is a magnetic card, the input / output connection of the IC card connector is a magnetic read head.

[0054]

According to the first aspect of the present invention, since there is no restriction on the mounting position of the stopper plate around the card insertion path, a notch can also be formed at the center of the front end of the IC card. In addition, only one type of IC card to be connected can be connected from various types of IC cards whose cutout positions are changed.

Since the shape of the notch is not limited to the taper, the shape of the notch of the IC card can be freely designed.

Further, since the stopper plate can be formed in the thick portion on the peripheral side surface forming the card insertion path, the size of the entire IC card connector can be reduced.
A stopper plate can be attached.

According to the second aspect of the present invention, since the opening surface of the insulating case having a U-shaped cross section is covered with the metal cover, the insulating case can be easily molded without using a slide mold or the like. Further, since the metal cover is used, a predetermined strength can be maintained while reducing the thickness of the entire connector. Also, if both legs of the metal cover are soldered to the pattern of the printed wiring board on which the IC card connector is mounted,
The rotation of the connector can be prevented. Furthermore, if both legs of the metal cover are soldered to the ground pattern of the printed wiring board, the electrical connection with the IC card is shielded by the metal cover, and the electrical connection can be electromagnetically shielded.

Since the stopper plate is formed by being cut and raised integrally from the metal cover used for these applications, it is not necessary to prepare the stopper plate as a separate part, and it can be formed in the thick portion of the metal cover. Therefore, the entire connector does not increase in size.

According to the third aspect of the present invention, in order to prevent erroneous insertion into a conventional IC card connector, an IC card having a tapered notch on one side of a front end is similarly prevented from being erroneously inserted. Can be inserted into the card insertion path and connected to the input / output connection unit. Therefore, the IC according to the present invention is completely compatible with the conventional IC card connector.
A card connector can be used.
