Description

  The present invention relates to an IC card connector, and more particularly, to an IC card connector that can make contact with an IC contact portion better.

At present, IC cards are used in various fields.
An IC card connector is used to exchange electrical information with these IC cards. The IC card connector is used to connect with a cash card used in a bank or a credit card, or it is used as an authentication card that is mounted on a car and automatically pays a highway charge. ing.

  Some IC card connectors are inserted in the IC card connector by sliding in the longitudinal direction of the card in parallel with the card surface. In this type of IC card connector, when the IC card is inserted, the contact for electrical connection with the IC card of the IC card connector is inserted while contacting the surface of the IC card. Before contact between the card and the contact, the card surface and the contact are always inserted in contact with frictional force, and when the IC card is pulled out, the card is contacted in the same way. Since the contact is to make extra contact, there is a problem that the contact is often worn and a contact failure occurs.

Therefore, when the IC card is inserted into and removed from the IC card connector, a mechanism is provided so that the contact comes into contact with the contact portion of the IC card when the insertion of the IC card is completed. A device has been devised to ensure good electrical contact with the card.
For example, FIG. 16 shows a conventional IC card connector 100, but the contact timing is devised by the operation of the contact.
The IC card connector of Conventional Example 1 shown in FIG. 16 is placed in a position opposite to the contact portion C1 of the IC card C at the position where the IC card C is completely inserted in the housing 101 which is the housing of the IC card connector 100. A plurality of contacts 102 are provided. The contact 102 is configured with a spring force so as to contact the contact portion C1 of the IC card C with a good contact pressure when the insertion of the IC card C is completed.

That is, as shown in the explanatory view showing the state immediately before the IC card C reaches the insertion completion position shown in FIG. 16A, one end of the contact 102 is positioned outside the housing 101 and other members such as a printed wiring board. And a contact end 102g which is a free end and abuts on the IC card C and is swung. The board connecting portion 102a is connected to the board by soldering or the like. Further, the contact 102 is provided with a housing fixing portion 102b for fixing the contact 102 to the housing 101 following the board connecting portion 102a. When the housing 101 is formed, the contact 102 is fixed by integrally forming the housing 101 and the housing fixing portion 102b.
The contact 102 forms a movable part having a spring force for making contact with the IC card C on the side opposite to the board connecting part 102a of the housing fixing part 102b. That is, a spring portion 102c that extends from the housing fixing portion 102b and is bent in a U shape is formed. The spring part 102c is a part ahead of the fixed part 102b, and the folded part 102d folded back in a U-shape is inserted into the fixed part 102b side from the abutting end 102g at the tip, that is, the abutting end 102g. The abutting end 102g is located on the side of the IC card C so as to abut against the tip of the IC card C to be inserted.

  A swing fulcrum portion 102e is provided between the folded portion 102d and the abutting end 102g of the spring portion 102c, and is placed further away from the IC card C than the folded portion 102d. Accordingly, the spring portion 102c of the contact 102 is located on the side farther from the IC card C than the contact end 102g, as shown in FIG.

  In Conventional Example 1 formed as described above, when the IC card C is inserted in the direction indicated by the white arrow shown in FIG. 16A, the insertion-side tip of the IC card C comes into contact with the contact end 102g. When the insertion is performed, the contact end 102g is pushed by the tip of the insertion side of the IC card C and is moved downward in the drawing, that is, toward the housing 101 side. The movement by the spring force at this time is centered around the swing fulcrum portion 102e, and the folded portion 102d moves to the opposite side of the housing 101, that is, upward due to the reaction caused by the contact end 102g side moving to the housing 101 side. Will be.

When the insertion of the IC card C further proceeds and the contact end 102g of the contact 102 reaches the lower surface side of the IC card C (the surface on which the contact portion C1 is provided), the folded portion 102d is moved upward, and FIG. As shown in 16 (b), the contact is made with the contact portion C1 of the IC card C to make electrical contact.
At this time, since the entire spring portion 102c of the contact 102 is pressed toward the housing 101 by the IC card C, the card contact portion 102f and the contact end 102g of the folded portion 102d contacting the contact portion C1 of the IC card C are The IC card C is in contact with the contact pressure.

In the conventional example 1, the IC card C is inserted into the IC card connector 100, and the contact 102 is not in contact with the surface of the IC card C, immediately before the IC card C is inserted and the insertion completion position is reached. The contact 102 abuts on the contact portion C1 of the IC card C. As a means for moving the contact 102 for realizing this, the contact 102 itself is swung by the IC card C, and the contact 102f is in contact with the contact C1 so that the contact 102f contacts the contact C1. The inserted IC card C is moved in the horizontal direction (in parallel with the housing 101 at an equal interval).
On the other hand, there has been a conventional example in which the IC card C itself is moved when the IC card C is inserted so as to make contact with the contact when the insertion is completed.

FIG. 17 shows a conventional example of an IC card connector having a mechanism for bringing the IC card C into contact with the IC card C when it is inserted. FIG. 17A shows the state before the IC card C is inserted and the IC card C and the contact are in contact with each other. FIG. 17B shows the IC card C in the insertion completion position and the contact between the IC card C and the contact. Represents a state in which the contact is completed.
In the conventional example 2, the IC card connector 200 is provided with a housing 201 formed of a synthetic resin so as to face the IC card C when the IC card C is mounted. The housing 201 is provided with a contact 202 at a position facing the contact portion C1 when the IC card C is mounted.
The contact 202 is bent at one end and protrudes from the side opposite to the IC card C of the housing 201 to provide a fixing portion 202a for electrical connection with a substrate or the like, and is fixed to the housing 201, and the other end is bent. It is bent and provided on the side of the IC card C with a spring force and can swing, and a contact part 202b that contacts the contact part C1 of the IC card C and makes electrical connection is provided at the tip end of the swinging end. Is provided. When the contact portion 202b is pressed by the IC card C, a good contact pressure is obtained by the spring force.

In addition, guide plates 203 are erected on both side surfaces of the housing 201 on the side intersecting with the IC card C insertion direction. The guide plate 203 is provided with a guide groove 203a. And the guide part (not shown) protruded by the both sides of the slide plate 204 is engage | inserted and latched by the guide groove part 203a, and a guide part (not shown) can move along the guide groove part 203a. Therefore, the slide plate 204 is movable with a guide portion (not shown) guided by the guide groove portion 203a.
This moving direction is the direction indicated by the white arrow in FIG. 17 from the insertion of the IC card C to the direction in which the IC card C is mounted at a predetermined position. The guide groove 203a moves the slide plate 204 to the contact 202 side (downward in the figure) when the guided slide plate 204 finishes moving toward the white arrow and the IC card C is mounted at a predetermined position. As shown, the left side in the figure is perforated downward.

  The slide plate 204 is provided on the side where the contact portion 202b of the contact 202 of the housing 201 protrudes substantially parallel to the housing 201. The IC card C is held between the slide plate 204 and the housing 201 by holding the IC card C. Is configured to slide together with the slide plate 204. The IC card C held on the slide plate 204 only enters the slide plate 204 from the beginning of insertion into the IC card connector 200 until it is held on the slide plate 204. When the IC card C is inserted to a predetermined position on the slide plate 204, A contact portion (not shown) provided on the card insertion tip side of the slide plate 204 is movable while being pressed by the guide card tip 203a by being pushed by the tip of the IC card C on the insertion side.

  In Conventional Example 2 formed as described above, the IC card C inserted between the slide plate 204 and the housing 201 is held by the slide plate 204. The state at this time is the state shown in FIG. When the insertion of the IC card C is further advanced from this state, when the tip of the IC card C presses the slide plate 204, the guide portion (not shown) of the slide plate 204 moves while being guided by the guide groove portion 203a. When the guide portion (not shown) reaches the inclined portion of the guide groove portion 203a and the insertion of the IC card C further proceeds, the slide plate 204 is guided by the guide groove portion 203a and moves closer to the housing 201 side. When moved to the housing 201 side, the IC card C reaches the mounting completion position.

  When the IC card C reaches the mounting completion position, the slide plate 204 moves to the housing 201 side, the contact part C1 of the IC card C comes into contact with the contact part 202b of the contact 202, and further presses the contact part 202b downward. Therefore, the contact portion 202b comes into contact with the contact portion C1 with a pressing force to complete the electrical connection.

  However, in Conventional Example 1 in which the contact 102 swings and moves downward to ensure the contact pressure between the contact 102 and the IC card C, the size of the plurality of contacts 102 varies, and the housing 101 and the contact 102 are integrally molded. It is difficult to make the contact pressure between the contact 102 and the IC card C constant due to factors such as variations in the mounting position at the time, and it is difficult to stabilize the contact pressure during mass production. did.

On the other hand, in the conventional example 2 in which the IC card C itself is moved to the contact 102 side to ensure the contact pressure between the IC card C and the contact 202, the slide plate 204 for moving the IC card C to the contact 202 side is the IC card C. There is a guide groove 203a on the side of the IC card C for guiding the movement to the side of the IC card C even though the IC card C is moved to the contact 202 side on the opposite side of the contact 202, and the guide of the slide plate 204 The part (not shown) is also on the side of the IC card C. For this reason, the guide groove 203a has a fulcrum for generating an urging force when the IC card C is urged toward the contact side, and the reaction force when the IC card C is urged toward the contact side warps the slide plate 204. For this reason, it is still difficult to obtain a good contact pressure between the IC card C and the contact 202.
Further, in the conventional example 2, when vibration is generated when the IC card connector 200 is mounted on a vehicle, the slide plate 204 warps more significantly, causing a contact failure due to vibration. .

  In view of the above problems, an object of the present invention is to provide an IC card connector that is unlikely to cause poor contact even when vibrations occur, such as when mounted on a vehicle, and that can obtain a good contact pressure.

  In this invention, the IC card connector has a structure that can reliably obtain a contact pressure when the IC card is moved to the housing side to electrically connect the contact and the IC card.

Provided with a housing made of an insulator, with a shield cover plate that is placed opposite to the housing with a predetermined distance and locked with the housing, and with a card insertion hole that opens one end of the opposite housing and shield cover plate And a contact that is electrically connected to the contact portion of the IC card inserted from the card insertion hole to the insertion completion position with contact pressure, and is an IC card between the housing and the shield cover plate. Can be slidably moved in the insertion / extraction direction, has a ride plate body that covers the shield cover plate facing surface of the IC card to be inserted, and can be held by exposing the housing facing surface of the inserted IC card to the housing side A card holder, and the end of the slide plate body on the card insertion side is inserted by an IC card. A pressing by the slide plate having a sliding movable card abutment in the insertion direction,
The slide plate body is provided with a pressing protrusion that protrudes toward the shield cover plate side with an inclination, and the shielding cover plate has a pressing protrusion facing position immediately before completion of IC card insertion from the pressing protrusion facing position before IC card insertion. A relief opening into which the pressing protrusion enters is drilled,
When the IC card is inserted, the pressing protrusion is released from the beginning of insertion until just before the insertion is completed and enters the opening and is moved in parallel with the housing so that the IC card does not come into contact with the contact. The contact and the contact portion of the IC card are electrically connected to each other with a pressing force by entering the lower side of the shield cover plate along the inclined portion of the protrusion and moving toward the housing side. IC card connector,

I will provide a. Therefore, in this IC card connector, the slide plate holds the IC card inserted from the insertion hole. When the IC card is inserted and pressed, the card contact portion of the slide plate is pressed by the IC card and slides to move the IC card. The moving direction of the slide plate at this time moves parallel to the housing because the pressing protrusion provided on the slide plate enters the escape opening formed in the shield cover plate.
Eventually, the insertion of the IC card proceeds and immediately before the insertion completion position, the pressing projection is located at the end of the opening, and when the insertion further proceeds, the inclined portion of the pressing projection is released to the end of the opening. The pressing protrusion is moved downward along the housing side of the shield cover plate, and the IC card is moved to the housing side. As a result, the contact portion of the IC card is pressed and brought into contact with the contact provided on the housing, and is electrically connected with a good pressing force.
In addition, in order to obtain a better contact state between the contact portion of the IC card and the contact,

  The pressing protrusions provided on the slide plate and the relief openings provided on the shield cover plate are provided at a plurality of locations.

In this configuration, the pressing force obtained from the shield cover plate for moving the IC card to the housing side by the slide plate is obtained at a plurality of locations.
Furthermore, in this invention,

One of the pressing protrusions provided on the slide plate is provided at the position of the slide plate body facing the contact portion of the IC card to be mounted with the IC card interposed therebetween.
In this configuration, the pressing protrusion presses the contact portion of the IC card from the back side of the IC card. As a result, the pressing force obtained by the pressing protrusion from the rigidity of the slide plate directly acts on the contact portion of the IC card.

Therefore, according to the present invention, the IC card and the contact are brought into contact immediately before the IC card mounting completion position when the IC card is inserted / removed, and therefore, the contact and the IC card do not slide while being in contact with each other. In addition to reducing contact wear of the contacts, the pressing force for contacting and contacting the IC card can be obtained from the rigidity of the entire shield cover plate covering the entire IC card, so that a good contact pressure can be obtained. .
And by obtaining good contact pressure, the contact between the IC card and the contact is less likely to be easily released even when an impact due to vibration or the like is applied to the entire IC card connector, and it has excellent earthquake resistance and stable contact. Can be maintained.

Furthermore, by providing the pressing protrusions and relief openings at a plurality of locations, the number of locations where the IC card is pressed toward the housing increases, so that a better pressing state can be obtained and the pressing state is stabilized. Can be provided.
Furthermore, by providing a pressing protrusion and a relief opening at the contact portion position of the IC card, a pressure for obtaining a contact pressure with the contact can be directly applied to the contact portion from the back side. Even if the part is oscillated and moved, the contact portion is not oscillated and moved, so that a more reliable and stable electrical connection between the IC card and the contact is possible.

  Reference numeral 1 denotes an IC card connector. As shown in FIG. 1, the IC card connector 1 can include an IC card C and includes a housing 2 provided with contacts 5 that are electrically connected to the IC card C made of a plate-like insulator. Further, a shield cover plate 3 made of a metal plate that is engaged with the housing 2 with a predetermined distance from the housing 2 is provided. The housing 2 and the shield cover plate 3 facing each other open one end of the four sides to form a card insertion hole 11, and the other three sides are locked and fixed.

The IC card C inserted from the card insertion hole 11 is formed of a plate-like body containing an IC chip, and has a contact portion C1 for exchanging information with the IC chip on the surface. Since the configuration of the IC card C is determined by the standard, the position of the contact portion C1 is determined.
In this embodiment, the insertion side refers to the side positioned in the direction in which the IC card C is inserted, the removal side refers to the side facing the insertion side, and the width direction or width side refers to the insertion side. The side orthogonal to the side shall be said.

Accordingly, as shown in FIGS. 12 to 14, the contact 5 is provided at a position facing the contact portion C1 when the IC card C is inserted from the card insertion hole 11 to the insertion completion position. One end of the contact 5 is positioned outside the housing 2 on the opposite side of the shield cover plate 3 to form a substrate fixing portion 51, and an intermediate portion 52 following the substrate fixing portion 51 is formed integrally with the housing 2. The other end is positioned so as to protrude toward the shield cover plate 3 to be inserted. The contact portion 53 extends from the intermediate portion 52 and has a spring force, and the tip side is provided by being bent into a protruding mountain shape toward the shield cover plate 3 side.
The contact 5 is installed at a position where the contact portion 53 does not contact the IC card C when the IC card C is inserted or during the insertion.

  The shield cover plate 3 is formed by pressing a metal plate, and one of the short side edges forms a card insertion hole 11. Further, the other side edge in the short side direction is bent toward the housing 2 that is installed oppositely to form a housing locking portion 31 and is locked and fixed to a locking projection provided on the housing 2. Further, a shield fixing portion 33 that is extended from the plate body 32 and bent in an L shape so that the tip is located on the lower surface of the housing 2 is formed on the side edge in the short direction. The shield fixing portion 33 is used for screw fixing when the IC card connector 1 is fixed to a frame plate (not shown) or a housing (not shown) of an electronic device. And since this shield fixing part 33 is integral with the shield fixing part 33, it can function as a shield earth when screw-fixed. A plurality of housing locking portions 31 are also provided on the side edge in the longitudinal direction of the shield cover plate 3 so as to be locked with the housing 2. The housing locking portion 31 is formed as a locking hole in this embodiment so as to be locked with a locking projection provided on the housing 2, but is not particularly limited, and the locking method is usually Any method may be used.

In this embodiment, in addition to the two points of the shield fixing portion 33, a hold down which is a shield ground is provided on the end portion side opposite to the end portion of the housing 2 where the shield fixing portion 33 is located. That is, the hold down 38. The hold-down 38 is integrally formed with the housing 2 and is provided as a hold fitting 38a between the position of the hold-down 38 and the end of the housing. The holding metal fitting 38a is provided with a plate contact provided on the shield cover plate 3 by screwing a female screw at the position of the hold down 38, opening on the back surface side, extending to the edge side surface of the housing 2 and bending the edge side surface. It is provided so as to be pressed and contacted with the portion 38b. Since the plate contact portion 38b comes into contact with the bent portion of the holding metal fitting 38a exposed to the edge side surface with a spring force, an external device such as a frame plate (not shown) screwed to the hold down 38 is used. And the shield cover plate 3 are electrically connected with each other.
Thus, by providing the hold-down 38, a total of four shielded earths are performed in this embodiment, and the conventional shield fixing part 33 has only two places, so that good shield grounding cannot be performed. The problem of the occurrence of the problem was solved.

Further, the shield cover plate 3 is provided with a slide groove 34 that can be slidably engaged with the slide plate 4. The sliding groove 34 is formed at the end of the plate body 32 on the width side. The drilling position of the sliding groove 34 is appropriately determined depending on the position of the sliding protrusion 41 provided on the slide plate 4.
Similarly, the shield cover plate 3 is provided with a positioning hole 35 for determining the initial position of the slide plate 4 before insertion of the IC card C. This positioning hole 35 is drilled at two locations, and the drilling position is appropriately determined depending on the position of the card guide portion 44 provided in the slide plate 4.
Similarly, the shield cover plate 3 has a second relief opening 37 into which the second pressing projection 47 provided on the slide plate 4 enters as well as the first relief opening 36 into which the first pressing projection 45 provided on the slide plate 4 enters. Drill. The first relief opening 36 and the second relief opening 37 are provided corresponding to the first pressing protrusion 45 and the second pressing protrusion 47, respectively, and the drilling position is appropriately determined depending on the positions provided on the slide plate 4. To do.

4 is a slide plate. The slide plate 4 is installed between the housing 2 and the shield cover plate 3 and is formed to be slidable from the card insertion hole 11 side to the card insertion hole 11 side.
The slide plate 4 is formed by pressing a metal plate to form a slide body 4a, and the length in the insertion direction sliding along with the IC card C is about half of the length in the longitudinal direction of the IC card C. The length in the width direction, which is the direction, is shorter than the length in the short direction of the shield cover plate 3. Therefore, when the slide plate 4 is installed between the housing 2 and the shield cover plate 3, the longitudinal direction is the width direction of the IC card C to be inserted, and the short direction is the insertion / extraction direction of the IC card C.
The slide plate 4 is provided with a sliding protrusion 41 for slidably engaging with the shield cover plate 3. As shown in FIG. 11 and the like, the sliding protrusion 41 is a slide located between the housing 2 and the shield cover plate 3, that is, on the back side of the shield cover plate 3, at the short-side end of the slide plate 4. It is bent and provided in an L shape so as to be located on the surface side of the shield cover plate 3 from the plate 4. The sliding projection 41 is positioned from the back side of the shield cover plate 3 to the surface side (plane side) through the sliding groove 34 and is hooked on the surface of the plate body 32 of the shield cover plate 3 so that the slide plate 4 is shielded. 3 is supported.
Thus, the slide plate 4 is slidably locked to the shield cover plate 3 by the sliding protrusion 41 and the sliding groove 34.

  In addition, a card abutting portion 42 that is bent toward the housing 2 side is provided at the insertion side end that is the longitudinal end of the slide plate 4, opposite to the sliding protrusion 41. Furthermore, the card | curd holding | maintenance part 43 bent in the L-shape so that it may mutually oppose may be provided in the width side edge part similarly. As shown in FIG. 11, the card holding portion 43 is provided with an interval in which the end portion of the IC card C can enter between the L-shaped surface and the slide body 4a. Therefore, the IC card C is inserted from the card insertion hole 11 and held by the card holding portion 43 on the slide plate 4, and the insertion side tip contacts the card contact portion 42. The card insertion hole 11 side of the card holding part 43 is widened by forming a lower guide part 43a with a gentle slope toward the housing 2, and the IC card C inserted from the card insertion hole 11 is inclined downward. Can be inserted between the card holding part 43 and the slide body 4a after being brought into contact with the lower guide part 43a and guided by the slope of the lower guide part 43a.

The card guide portion 44 provided on the slide plate 4 determines the initial position of the slide plate 4 before insertion of the IC card C in the IC card connector 1. Two card guide portions 44 are provided at the removal side end so as to protrude from the removal side end of the slide body 4a toward the card insertion hole 11 side. The card guide portion 44 is provided obliquely toward the shield cover plate 3 and is further bent so that the tip of the card guide portion 44 comes into contact with the edge of the positioning hole 35 formed in the shield cover plate 3.
The slide plate 4 is urged by a coil spring (not shown) so that the tip of the card guide portion 44 is always in contact with the edge of the positioning hole 35 of the shield cover plate 3 when the IC card C is not mounted. . This biasing is such that one end of the coil spring is locked to an appropriate position of the housing 2 or the shield cover plate 3, and the other end is locked to an appropriate position of the slide plate 4 so that the spring force of the coil spring is applied in the removal direction. However, it is only necessary to perform the same operation as that performed by a conventional connector or the like.

Further, the slide body 4a of the slide plate 4 projects toward the shield cover plate 3 at a position facing the contact portion C1 of the IC card C in a state where the mounted IC card C is in contact with the card contact portion 42. A first pressing protrusion 45 is provided. The first pressing protrusion 45 is provided in a mountain shape so as to be inclined toward the top of the protrusion.
The first pressing protrusion 45 is inserted from before the insertion of the IC card C to the innermost part, the card abutting portion 42 is pressed by the IC card C, the sliding plate 4 starts sliding movement, and the IC card C is mounted completely. Until immediately before, the inclined portion 46 of the first pressing projection 45 is slid and moved while entering the first relief opening 36 formed in the shield cover plate 3, and the insertion side end of the first relief opening 36 is inserted. It is provided at a position where it abuts against 36a. Thereafter, in the IC card C mounting completion position, the first pressing projection 45 is guided to the insertion side end 36a of the first relief opening 36 at the position where the IC card C is completely installed, and is below the shield cover plate 3, that is, on the housing 2 side. It is provided at a position where it slides and moves downward. Therefore, the slide plate 4 itself is moved to the housing 2 side by the inclined portion 46 of the first pressing projection 45 being guided by the insertion side end 36a of the first relief opening 36 and moving downward to the housing 2 side. Moved to.
Then, at the IC card mounting completion position, the contact portion C1 of the IC card C and the contact portion 53 of the contact 5 are in an electrically connected state with a good pressing force by the spring force of the contact 5. .

  The second pressing protrusion 47 is provided in the vicinity of the four ends of the slide plate 4. Then, the second pressing protrusion 47 is inserted from before the IC card C insertion to the innermost part in the same manner as the first pressing protrusion 45, and the card contact part 42 is pressed by the IC card C, and the slide plate 4 slides. Until the IC card C reaches the mounting completion position, the inclined portion 48 of the second pressing protrusion 47 is slid and moved while entering the first relief opening 37 formed in the shield cover plate 3. The first escape opening 37 is provided at a position where it comes into contact with the insertion side end 37a. After that, the second pressing protrusion 47 has an inclined portion 48 guided to the insertion side end portion 37a of the second relief opening 37 at the IC card C mounting completion position, so that the lower side of the shield cover plate 3, that is, the housing 2 side. It is provided at a position where it slides and moves downward. Therefore, the slide plate 4 slides as the inclined portion 48 of the second pressing projection 47 together with the first pressing projection 45 is guided by the insertion side end 37a of the second relief opening 37 and moves downward toward the housing 2 side. The plate 4 itself is also moved to the housing 2 side.

Thus, the positional relationship between the first pressing projection 45 and the first relief opening 36 and the positional relationship between the second pressing projection 47 and the second relief opening 37 are in contact with each other at the same position, and thereafter The first pressing protrusion 45 and the second pressing protrusion 47 are provided so as to slide while moving downward toward the housing 2 at the same time.
In this embodiment, the second pressing projection 47 and the second relief opening 37 are provided. However, the second pressing projection 47 and the second relief opening 37 are not necessarily provided, and the slide plate 4 is slidably moved. However, the inclined portion 46 of the first pressing protrusion 45 may be formed long in the width direction so that it can be smoothly lowered to the housing 2 side. In this embodiment, the first pressing protrusion 45 is provided so as to face the contact portion C1 of the mounted IC card C. However, the first pressing protrusion 45 may be provided so as to be shifted from the position, while the slide plate 4 slides. It is sufficient that the contact portion C1 of the IC card C and the contact 5 can be brought into good contact with each other by descending in the housing 2 direction.

  The card guide portion 44 of the slide plate 4 and the slide groove 34 of the shield cover plate 3 described above have the first pressing projection 45 guided to the insertion side end portion 36a of the first relief opening 36 and the housing 2. The peripheral portion on the insertion side of the sliding groove 34 in which the sliding projection 41 is positioned is inclined to the housing 2 side so that the card guide portion 44 can be lowered to the housing 2 side at the same timing as the position at which the downward movement starts to the side. A portion 34a is provided.

  Reference numeral 6 denotes an ejecting device. When the inserted IC card C reaches the innermost portion and reaches the mounting completion position, a locking portion (not shown) provided on the slide plate 4 is locked. By holding the slide plate 4 in this position and pressing the push button 61, the latching portion (not shown) is unlocked to free the slide plate 4, and the spring force of a coil spring (not shown) As a result, the card guide portion 44 comes into contact with the end portion of the positioning hole 35 to return the slide plate 4 to the initial position. In addition, the coil spring etc. which give return force to the eject apparatus 6 and the slide plate 4 are implemented conventionally, and a detailed description is abbreviate | omitted.

The operation of the embodiment of the present invention will be described below.
As shown in FIG. 12, when the IC card C is inserted from the card insertion hole 11, the insertion side tip of the IC card C first comes into contact with the card contact portion 42 of the slide plate 4. Even if the IC card C is bent and inserted into the IC card C, it comes into contact with the inclined portion of the card guide portion 44 or the lower guide portion 43a and along the gentle slopes of the guide portions 44 and 43a. The card holder 43 is inserted between the slide body 4a.
When the insertion continues after the IC card C abuts against the card abutment portion 42, the slide plate 4 is slid to the insertion side against the biasing force of a coil spring (not shown). At this time, since the slide protrusion 41 is slidably engaged with the slide groove 34 of the shield cover plate 3, the slide plate 4 is slid and moved while being guided by the slide groove 34.
At this time, the IC card C and the contact 5 are not in contact.

The sliding movement of the slide plate 4 is continued and eventually reaches the position shown in FIG. That is, the inclined portion 46 of the first pressing projection 45 reaches and contacts the insertion side end 36 a of the first relief opening 36, and the inclined portion 48 of the second pressing projection 47 is on the insertion side of the second relief opening 37. It reaches and abuts the end 37a. At this time, the sliding protrusion 41 is positioned immediately before the inclined portion 34a provided in the peripheral portion of the sliding groove 34, and thereafter can be moved along the inclined portion 34a.
In the position of the slide plate 4 shown in FIG. 13, the IC card C and the contact 5 are not yet in contact with each other and have an appropriate designed interval.

  When the IC card C is further pressed from the position shown in FIG. 13 and the insertion is continued, the inclined portion 46 of the first pressing protrusion 45 is guided by the insertion side end 36a of the first relief opening 36 and becomes the housing 2 side. The IC card C continues to be inserted by sliding while being moved downward. Similarly, the second pressing protrusion 47 is guided by the insertion side end 37a of the second relief opening 37 and is slid while being moved downward on the housing 2 side to continue the insertion of the IC card C. . At this time, since the card holding portion 43 guided by the sliding groove 34 is provided with the inclined portion 34a around the sliding groove 34, the card holding portion 43 can be moved while being lowered to the housing 2 side.

When the slide plate 4 continues to slide while being lowered, the IC card C is also lowered at the intermediate position between the position shown in FIG. 13 and the position shown in FIG. It will come into contact. This contact is preferably as short as possible of the IC card C mounting completion position shown in FIG. 14 and should be a position where the contact pressure of the contact 5 is sufficiently applied.
The IC card C mounting completion position is a position where the sliding protrusion 41 comes into contact with the insertion-side end of the sliding groove 34 so that the sliding groove 34 and the sliding protrusion 41 are positioned so as to be in this position. Designed to. Note that the mounting completion position may be formed by, for example, notching a part of the shield cover plate 3 so as to come into contact with the insertion-side tip of the slide plate 4 and bending it to the slide plate 4 side.
Then, at the IC card C mounting completion position shown in FIG. 14, the contact 5 is pushed downward against the spring force and contacts the contact portion C1 of the IC card C with a good pressing force to make electrical connection. Is made.
When the IC card C is released and the IC card C is removed, the eject button 61 of the ejecting device 6 is pressed to release the locking of the slide plate 4 by the ejecting device 6, and a coil spring (not shown) The slide plate 4 is moved to the insertion hole 11 side, that is, the removal side by the spring force, and the ejection operation is completed.

  In this embodiment, the eject device 6 is provided. However, the IC card C may be formed so that the user can directly insert and remove the IC card C without providing the eject device 6.

  The present invention can be used for an IC card connector to which an IC card is mounted and electrically connected. In particular, there is a high possibility that vibration or the like occurs, and the contact portion and contact of the IC card have a good contact pressure. It is more effective when used for an IC card connector that is used in a place that needs to be brought into stable contact.
