Description

  The present invention relates to a card connector into which a card such as a memory card or a SIM (subscriber identification module) card is inserted.

  In the case of a card connector, it is necessary to hold the card so that it does not come out of the proper insertion position even if a slight impact is applied while the card is inserted.

  Patent Document 1 discloses a card connector in which a holding force is improved by placing an eject plate acting as a holding member of an inserted card along a guide wall of a housing.

JP 2003-217738 A

  In the technique of the above-mentioned Patent Document 1, the eject plate is placed along the guide wall of the housing, but when an impact is applied, the engaging portion of the eject plate is deformed in a direction to be crushed, and the holding force is further improved. I can't hope. If the holding force is further increased, the card connector may be increased in size, such as requiring a large holding member.

  An object of this invention is to provide the card connector which raised holding force, suppressing the enlargement.

The card connector of the present invention that achieves the above object is a card connector in which a receiving space for receiving an insertion body that has been inserted in the insertion direction and has a locking recess formed on the side surface in the width direction intersecting the insertion direction. And
A locking plate having a shape projecting inwardly into the receiving space and having a locking portion that enters the locking recess of the insertion body received in the receiving space and locks the insertion body at the end in the insertion direction;
A slider that is arranged so as to overlap the locking plate, is slidable in the insertion direction, and is pushed by the tip of the discharge pin that has been inserted and slides to the back in the insertion direction;
An eject lever that is arranged on the back side of the receiving space and extends in the width direction and has a rotation shaft in the middle, and is rotated when the first end is pushed by the slider that slides on the back side in the insertion direction to push the insertion body at the second end. And
The locking plate is bent downward by being pushed by a discharge pin that has been inserted and formed on a slope that rises toward the back in the insertion direction at the end in the insertion direction of the locking plate. It is characterized by having an unlocking part that moves the base plate downward and removes it from the locking recess.

  The card connector of the present invention releases the locking between the locking recesses of the insert by bending the locking plate by inserting the discharge pin. Acts as a rigid body. Therefore, even if a strong impact is applied in the direction in which the insert is pulled out, the insert is kept securely.

  Here, in the card connector of the present invention, it is preferable that the locking portion is formed on a slope together with the locking release portion.

  When the locking part is formed on the slope, the locking part is pushed by the insertion body and escapes from the passage when the insertion body is inserted into the receiving space. A simple mechanism or the like is unnecessary, and a simple structure is realized accordingly.

  Further, in the present invention, the insert may be a card itself, and a locking recess may be formed in the card itself. Alternatively, the insert may have a card tray on which a card is mounted and inserted into the receiving space together with the card, and a locking recess may be formed in the card tray. In the case of a card connector of a type in which a locking recess is formed in the card tray and the card is mounted on the card tray and inserted into the receiving space, the card itself does not require consideration regarding the locking structure. Therefore, the present invention is more suitable for a type of card connector having a card tray.

  According to the card connector of the present invention described above, inadvertent removal of the inserted body in the inserted state can be prevented without increasing the size.

It is a top view of the state which extracted the tray of the card connector as 1st Embodiment of this invention. It is a top view of a card connector in the state where a metal shell was removed from the card connector shown in FIG. FIG. 6 is a plan view and a cross-sectional view of the card connector in a state where the tray is received in the receiving space.

  FIG. 2 is a plan view of the card connector with the metal shell removed from the card connector shown in FIG. Here, it may be called a card connector regardless of the presence or absence of a metal shell.

  FIG. 3 is a plan view (A) and a cross-sectional view (B) of the card connector in a state where the tray is received in the receiving space.

  4 and 5 are a plan view and a cross-sectional view of the card connector, respectively, showing a state in which the tray received in the receiving space is being pushed out and a state after being pushed out.

  3 to 5, the metal shell 20 is removed. In FIGS. 3 to 5, both are overlaid so that the positional relationship between the housing assembly 10 and the tray 30 can be understood. 3 to 5, (A) is a plan view, and (B) is a cross-sectional view taken along the arrow AA shown in FIG. 3 (A).

  The card connector 1 includes a housing assembly 10 (see FIG. 2), a metal shell 20 (see FIG. 1), and a tray 30. A large opening 31 is formed at the center of the tray 30, and a support base 32 is provided at the edge of the opening. On this tray 30, a SIM card (not shown) is supported in a state where the periphery of the bottom surface of the SIM card is placed on a support base 32 and a wide area at the center of the bottom surface of the SIM card is exposed downward from the opening 31. The

  Between the housing assembly 10 and the metal shell 20, an insertion port 1a into which the tray 30 is inserted is formed. In addition, a receiving space 1b (see, for example, FIG. 2) for receiving the SIM card placed on the tray 30 is formed in the back of the insertion slot 1a. The tray 30 is inserted into the housing assembly 10 in the insertion direction indicated by the arrow A. In the present embodiment, the tray 30 alone or a combination of the tray 30 and the SIM card placed on the tray 30 corresponds to an example of an insert according to the present invention.

  The tray 30 has a locking recess 33 formed on the side surface in the width direction that intersects the insertion direction (arrow A direction). On the other hand, the housing assembly 10 includes a locking plate 12 (see, for example, FIG. 3B). The locking plate 12 is provided with a locking portion 121 having a shape protruding inwardly from the locking release portion 122 at the end on the near side in the insertion direction (arrow A direction). The locking part 121 and the locking release part 122 are formed on an inclined surface that climbs toward the back side in the insertion direction (arrow A direction). When the tray 30 is received in the receiving space 1b, the locking portion 121 has a role of entering the locking recess 33 of the tray 30 to lock the tray 30 and preventing the tray 30 from being accidentally pulled out. . Moreover, the latch release part 122 bears the role which cancels | releases the latch by the latch part 121 as mentioned later.

  The housing assembly 10 is provided with a resin housing 11 serving as a base thereof. The housing 11 has an opening 113 through which the locking portion 121 and the locking releasing portion 122 of the locking plate 12 can be looked down. Is formed. The housing assembly 10 is provided with a plurality of metal contacts 13 formed integrally with the housing 11. Each contact 13 has a board connecting portion 131 that is solder-connected to the surface of a circuit board (not shown). A pad for electrical connection is formed on the lower surface of the SIM card placed on the tray 30. These contacts 13 are in contact with the pads on the lower surface of the SIM card placed on the tray 30 and received in the receiving space 1b, and have a role of electrically interconnecting the SIM card and the circuit board.

  The housing assembly 10 further includes a slider 14 and an eject lever 15.

  The slider 14 is a metal member disposed so as to overlap the locking plate 12, extends in the insertion direction (arrow A direction), and is slidable in the insertion direction (arrow A direction) with respect to the housing 11. It is supported by the housing 11.

  The tray 30 is formed with a through hole 34 into which an external pin 40 (see FIGS. 4 and 5) for pushing the slider 14 is inserted, and an opening 112 for receiving the pin 40 is also formed in the housing 11. Has been.

  The eject lever 15 is a metal member that is disposed on the back side of the receiving space 1b and extends in the width direction intersecting with the insertion direction (arrow A direction), and the middle of the eject lever 15 is rotatably supported by the housing 11. A shaft 151 is formed. The eject lever 15 rotates counterclockwise (in the direction of arrow D shown in FIGS. 4 and 5) when the first end 152 is pushed by the slider 14 slid in the insertion direction (arrow A direction). The tray 30 is pushed out by the second end 153.

  As shown in FIGS. 1 and 2, the tray 30 that has been taken out is inserted from the insertion port 1a in the insertion direction (arrow A direction) and received in the receiving space 1b. Then, since the locking portion 121 of the locking plate 12 is formed on the slope, the tray 30 pushes down the locking portion 121. As described above, the housing 11 has the opening 113 through which the locking portion 121 and the locking release portion 122 of the locking plate 12 can be viewed. Therefore, the locking portion 121 pushed down by the tray 30 and the locking releasing portion 122 connected to the locking portion 121 are not disturbed by the housing 11 and are directed downward (the direction of the arrow E shown in FIGS. 4 and 5). ) To secure the passage of the tray 30. When the tray 30 is further inserted in the insertion direction (arrow A direction), as shown in FIG. 3, the second end 153 of the eject lever 15 is pushed by the tray 30 and rotates clockwise (direction of the arrow C). It rotates, and the slider 14 is slid to the front side (arrow B direction shown in FIG. 4) in the insertion direction. When the tray 30 is inserted until the locking recess 33 reaches the position of the locking portion 121 of the locking plate 12, the locking portion 121 of the locking plate 12 enters the locking recess 33 of the tray 30 and Prevent inadvertent omissions.

  Here, the locking plate 12 is formed through a shearing process of a metal plate, and the locking part 121 of the locking plate 12 is arranged in a posture in which the surface of the plate material before the shearing process is directed vertically. Since it extends toward the side surface of the tray 30 and enters the locking recess 33, the locking portion 121 acts as a rigid body in the insertion direction (arrow A direction). Therefore, even if an impact is applied in the direction in which the tray 30 is pulled out, deformation that causes the locking portion 121 to be crushed is prevented, the desired holding force is maintained, and the tray 30 is firmly prevented from coming off.

  As shown in FIG. 4, when the pin 40 is inserted from the through hole 34 of the tray 30 and the slider 14 is pushed into the insertion direction (arrow A direction) by the pin 40, the tip of the pin 40 is engaged with the locking plate 12. It hits the stop release part 122. Since the unlocking portion 122 is formed on the slope, it is bent downward (in the direction of arrow E shown in FIGS. 4 and 5) when pressed by the tip of the pin 40. Then, the pin 40 strikes the slider 14 while bending the locking release portion 122 of the locking plate 12 downward, and slides on the locking plate 12 while pushing the slider 14 in the insertion direction (arrow A direction). Proceed as follows. By this movement, the slider 14 pushes the first end 152 of the eject lever 15 and the eject lever 15 rotates counterclockwise (in the direction of the arrow D). (B direction). Here, when the pin 40 pushes down the locking release part 122, the locking part 121 provided on the side of the locking release part 122 of the locking plate 12 is also locked together with the locking release part 122. It moves downward to a position where the engagement with the recess 33 is released. Therefore, when the tray 30 is pushed by the eject bar 15, the tray 30 is pushed out to the state shown in FIG. 5 through the state shown in FIG. After being pushed out to the state shown in FIG. 5, a fingernail or the like is hung on the tray 30 and the tray 30 is pulled out.

  In the card connector 1 of the present embodiment, the tray 30 in a state where a SIM card (not shown) is placed is inserted. However, the present invention can also be applied to a card connector for inserting a memory card other than a SIM card on a tray.

  The card connector 1 of this embodiment is a type of card connector in which a SIM card is placed on the tray 30 and inserted. However, the present invention is also applicable to a type of card connector in which a card such as a memory card is inserted without a tray. Can be applied. However, in that case, the card itself needs to be provided with a locking recess.
