A contact that contacts a terminal of the card;
A cam portion formed with a cam groove;
A cam pin having a tip inserted into the cam groove, and a cam pin that moves relative to the cam portion in accordance with the movement of the slider and restricts a moving range of the slider;
The cam groove
A release node corresponding to the release position of the slider before being pushed by the card or the card tray;
An abutment node corresponding to an abutment position against which the slider that is pushed in from the release position in the insertion direction by an operating force abuts,
A temporary holding node corresponding to a temporary holding position that is held in the middle of returning the slider from the abutting position to the take-out direction opposite to the insertion direction with the release of the operating force;
The slider is pushed again in the insertion direction from the temporary holding position by the operation force again, and is formed in a normal route passing through a terminal contact node corresponding to a contact position where the terminal of the card contacts the contact. It has been
The terminal contact node is arranged at a position away from the release node than the butting node.

  In the card connector of the present invention, the movement range of the slider and the card tray (or card) is regulated by the cam groove and the cam pin. When the card tray (or card) is inserted into the card connector, the slider pressed against the card tray (or card) hits at the abutting position and temporarily holds when the operating force of the card tray (or card) is released. Return to position. Therefore, the card tray (or card) is temporarily held by the card connector. When the card tray (or card) is inserted (pressed) again, the slider moves to a contact position ahead of the abutting position in the insertion direction, and the terminal of the card comes into contact with the contact. Here, when the operating force of the card tray (or card) is released, the slider returns to the release position, and the card tray (or card) is ejected from the card connector.

  When this card connector is provided in, for example, a device housing having an insertion hole, for example, the card is inserted from the insertion hole to the abutting position and temporarily held at the temporary holding position. Thereafter, for example, the card tray (or card) is inserted to the contact position by a lid member that closes the opening, and the terminal and the contact are brought into contact with each other. In the case of taking out the card tray (or card), the card is returned only by removing the lid member from the opening without directly operating the card tray (or card).

  Even when the card connector of the present invention is provided in the inner part of a device housing having a narrow insertion hole that does not allow a finger or the like to enter, first the card tray (or card) is directly operated with the finger or the like until temporary holding. After that, the card tray (or card) can be inserted to the contact position of the terminal by using the closing operation of the lid member. Further, the card tray (or card) is ejected simply by removing the lid member from the opening. Thus, according to the card connector of the present invention, it is easy to mount and take out the card tray (or card).

Also has a second abutment node corresponding to the second abutment position against which the slider pushed in the insertion direction abuts, and with the release of the operating force after moving to the second abutment position In the middle of returning to the take-out direction, the slider reaches the contact position and is held at the contact position, and the cam groove is further pushed in the insertion direction from the contact position by the operation force again. It is preferable that the cam groove is formed in a route that returns from the terminal contact node to the release node via the release operation node.

  In this card connector, the slider is pushed to the second abutting position behind the temporary holding position, and then reaches the contact position with the release of the operating force. Then, the slider receives the operation force again and is pushed into the release operation position, and then returns to the release position by releasing the operation force. In the case of this preferable configuration, even when there is no lid member that continues to push the card tray (or card), the card tray (or card) is brought into contact with the terminal by pushing the card tray (or card) using a rod-shaped jig. Can be held in position.

  FIG. 1 is a plan view of a card connector according to a first embodiment of the present invention. FIG. 1 shows a card connector C1 and a card tray T on which a card J is mounted. The card J is an IC card with a built-in IC, for example, a micro SIM card. The card J has a substantially rectangular plate shape and is provided with eight terminals P (P1 to P8). The card tray T functions as an adapter for attaching the card J to the card connector C1. The card tray T is inserted into the card connector C1 together with the card J with the card J mounted. A direction in which the card connector C1 and the card J are inserted into the card connector C1 is referred to as an insertion direction S. The terminals P1 to P8 of the card J are arranged on the lower surface in the posture shown in FIG. 1, that is, on the surface opposite to the surface appearing in FIG. In the present embodiment, among the eight terminals P1 to P8, six terminals P2 to P4 and P6 to P8 are connected.

  The card connector C1 includes a housing 1, a shell 2, six contacts 3, a slider 4, an urging member 6 such as a coil spring, a cam pin 7, and a cam portion 8. In FIG. 1, the state where the shell 2 is removed is shown by a solid line, and only the outer shape of the shell 2 is shown by a broken line.

  The housing 1 is a molded product made of an insulating resin material. The shell 2 is formed by punching and bending a metal plate. Both the housing 1 and the shell 2 have a substantially rectangular outer shape. The shell 2 is attached to the housing 1 so as to cover the housing 1. A receiving space 11 for receiving a plate-shaped card J is formed between the housing 1 and the shell 2. The receiving space 11 is a cavity opened to the outside through the insertion port 11a. The card J is inserted into the receiving space 11 from the insertion port 11a in the insertion direction S.

  The contact 3 is a member for electrically connecting to the terminals P2 to P4 and P6 to P8 of the card J. The contact 3 is formed by punching and bending a metal plate. The contact 3 is fixed to the housing 1 by insert molding or the like. The housing 1 is provided with a contact hole 11h. One end of the contact 3 enters the receiving space 11 at the position of the contact hole 11h. The other end of the contact 3 is soldered to a conductor pattern of a circuit board (not shown) to which the card connector C1 is attached.

  The slider 4, the coil spring 6, the cam pin 7, and the cam portion 8 are disposed in a receiving space 11 formed between the housing 1 and the shell 2. The slider 4, the coil spring 6, and the cam pin 7 constitute a so-called push / push type ejection mechanism.

  The slider 4 is a molded product made of a resin material. The slider 4 is supported by the housing 1 so as to be slidable in the insertion direction S. The slider 4 has a pressing portion 41 that is bent like a bowl and protrudes into the insertion path of the card tray T. The pressing portion 41 is disposed at a position facing the front end edge E of the card tray T in a posture in which the card tray T is inserted, and is a portion pressed against the front end edge E of the card tray T. When the pressing portion 41 of the slider 4 is pushed by the card tray T, the slider 4 moves in the insertion space 11 in the insertion direction S. On the other hand, the slider 4 moves in the direction opposite to the insertion direction S to push the card tray T by the pressing portion 41.

  The urging member 6 is a compression coil spring disposed between the slider 4 and the housing 1. The urging member 6 urges the slider 4 in the take-out direction R opposite to the insertion direction S.

  The cam portion 8 is a portion formed integrally with the housing 1 as a part of the housing 1. A cam groove 80 is formed in the cam portion 8. The cam groove 80 will be described later.

  The cam pin 7 is a metal rod-shaped member. The cam pin 7 is bent at both ends in the same direction and has a horizontally long U-shape. One end of the cam pin 7 is held by the slider 4. Therefore, the cam pin 7 moves with respect to the cam portion 8 following the movement of the slider 4. The end of the cam pin 7 opposite to the end held by the slider 4 is in the cam groove 80 of the cam 8. The end of the cam pin 7 that has entered the cam groove 80 moves along the cam groove 80 in accordance with the movement of the slider 4. The cam pin 7 restricts the movement range of the slider 4 according to the shape of the cam groove 80.

  FIG. 2 is an enlarged view of the cam portion 8 shown in FIG.

  The cam groove 80 formed in the cam portion 8 shown in FIG. 2 is a heart cam type groove partially deformed. The cam groove 80 forms a normal path that passes through the release node 81, the butting node 82, the temporary holding node 83, and the terminal contact node 84.

  The release node 81 is provided on the most front side in the insertion direction S in the cam groove 80. The release node 81 corresponds to the release position of the slider 4 before being pushed by the card tray T, that is, the position closest to the insertion direction S as shown in FIG.

  The butting node 82 is provided on the back side in the insertion direction S with respect to the release node 81. The abutting section 82 corresponds to an abutting position where the slider 4 that the card tray T is pushed in the insertion direction S from the released position abuts.

  The temporary holding joint 83 is provided on the front side in the insertion direction S with respect to the butting joint 82 and on the back side in the insertion direction S with respect to the release joint 81. The temporary holding joint 83 corresponds to a temporary holding position where the slider 4 (see FIG. 1) is held in the middle of returning from the abutting position in the extraction direction R.

  The terminal contact node 84 is provided on the back side in the insertion direction S with respect to the temporary holding node 83. The terminal contact node 84 is disposed at a position farther from the release node 81 than the butting node 82. That is, it is provided in the insertion direction S back side with respect to the butting node 82. The terminal contact node 84 is provided on the innermost side in the insertion direction S in the cam groove 80.

  The cam pin 7 (see FIG. 1) is guided by a step provided at the bottom of the cam groove 80, and in the cam groove 80, the release joint 81, the butting joint 82, the temporary holding joint 83, and the terminal contact joint 84 in this order. Moving. This reverse movement is prevented by the step. The cam pin 7 (see FIG. 1) moves in the cam groove 80 and restricts the movement of the slider 4 at each node.

  FIG. 3 is a view showing a state in which a card tray is inserted into the card connector shown in FIG.

  A card connector C1 shown in FIG. 3 is built in a housing B of an electronic device represented by, for example, a portable information device. More specifically, the card connector C1 is attached to a circuit board (not shown) provided in the housing B by solder connection. The housing B has an insertion hole Bh for inserting the card tray T. The card connector C <b> 1 is disposed in the inner back portion of the housing B rather than the outer wall Ba of the housing B.

  The card tray T on which the card J is mounted is inserted into the card connector C1 through the insertion hole Bh of the housing B. In the state shown in FIG. 3, the card tray T is in contact with the slider 4 but is in a state before the slider 4 is pressed. That is, the slider 4 of the card connector C1 is in the release position, and the end of the cam pin 7 (hereinafter simply referred to as the cam pin 7) is in the release node 81 of the cam groove 80. At this time, the edge Ta on the near side of the card tray T protrudes in the take-out direction R from the outer wall Ba of the housing B.

  From the state shown in FIG. 3, when the card tray T is pushed in the insertion direction S in response to an operation force due to a pushing operation of a finger or the like, the card tray T moves in the insertion direction S while pushing the slider 4 in the insertion direction S. Moving. At this time, the cam pin 7 also moves in the insertion direction S as the card tray T moves.

  FIG. 4 is an enlarged view of the cam portion 8 shown in FIG.

  When the card tray T is pushed in the insertion direction S, the cam pin 7 moves from the release node 81 along the cam groove 80 in the insertion direction S and hits the butting node 82. The position of the cam pin 7 at the butting node 82 corresponds to the butting position where the slider 4 pushed in the insertion direction S from the release position shown in FIG.

  FIG. 5 is a diagram illustrating a state in which the slider has moved to the temporary holding position.

  When the operation force is released when the slider 4 is in the above-described abutting position, the slider 4 pushes the card tray T back in the ejecting direction R by the urging force of the urging member 6. At this time, the cam pin 7 moves from the abutting node 82 along the cam groove 80 in the take-out direction R, and abuts on the temporary holding node 83 as shown in FIG. Therefore, the slider 4 and the card tray T are held at the temporary holding position shown in FIG.

  Since the card connector C1 of this embodiment is disposed in the inner part of the housing B, the contact 3 of the card connector C1 is a card at the temporary holding position shown in FIG. The terminals P2 to P4 and J6 to P8 of J are not in contact. The temporary holding position shown in FIG. 5 is a position where the card tray T is held to such an extent that it is difficult to drop off from the card connector C1. In the temporary holding position shown in FIG. 5, the edge Ta on the near side of the card connector C1 is arranged on substantially the same plane as the outer wall Ba of the housing B.

  FIG. 6 is an enlarged view of the cam portion 8 shown in FIG.

  When the card tray T is pushed in the insertion direction S, the cam pin 7 moves from the temporary holding node 83 along the cam groove 80 in the insertion direction S and moves to the terminal contact node 84.

  FIG. 7 is a diagram illustrating a state in which the slider has moved to the terminal contact position.

  When the operation force is applied again when the slider 4 is in the temporary holding position shown in FIG. 5, the card tray T moves the slider 4 in the insertion direction S by the operation force. At this time, the cam pin 7 moves from the temporary holding node 83 along the cam groove 80 in the insertion direction S, and moves to the terminal contact node 84 as shown in FIG. The slider 4 moves to the terminal contact position shown in FIG. 7, and the contact 3 contacts the terminals P2 to P4 and P6 to P8. The state shown in FIG. 7 is a state in which the card J is completely attached to the card connector C1.

  More specifically, the card tray T is pushed in the insertion direction S by the lid member L that closes the insertion hole Bh of the housing B. The lid member L is a molded product made of, for example, a resin material, and has a width substantially equal to the opening of the insertion hole Bh. More specifically, the lid member L is a waterproof cap, and is press-fitted into the insertion hole Bh to close the insertion hole Bh in a watertight manner. The lid member L is held by the housing B so as not to be removed from the insertion hole Bh unless a pulling force is applied from the outside. The lid member L has a thickness (dimension in the insertion direction S) equal to the distance from the temporary holding node 83 to the terminal contact node 84 in the insertion direction S of the cam groove 80. Therefore, the lid member L is located on the substantially same plane as the outer wall Ba of the housing B in a state where the lid member L has completed the closing of the insertion hole Bh, and the cam pin 7 extends from the temporary holding joint 83 to the terminal contact joint 84. Move to. At this time, the slider 4 moves to the terminal contact position shown in FIG. 7, and the contact 3 contacts the terminals P2 to P4 and P6 to P8. Here, the combination of the card connector C1, the housing B, and the lid member L corresponds to an embodiment of the connector mounting structure of the present invention.

  The card tray T is held in a state where the slider 4 is pushed into the terminal contact position shown in FIG.

  When removing the card tray T from the card connector C1 (that is, the housing B), the lid member L is pulled out from the insertion hole Bh of the housing B. When the operation force is released when the slider 4 is at the terminal contact position shown in FIG. 7, the slider 4 pushes the card tray T back in the take-out direction R by the urging force of the urging member 6. At this time, it is not necessary to directly operate the card tray T with fingers.

  FIG. 8 is an enlarged view of the cam portion 8 shown in FIG.

  When the card tray T is pushed back in the removal direction R, the cam pin 7 moves from the terminal contact node 84 along the cam groove 80 in the removal direction R and moves to the release node 81. The slider 4 and the card tray T move to the release position shown in FIG. As a result, as shown in FIG. 3, the edge Ta on the near side of the card tray T protrudes in the take-out direction R from the outer wall Ba of the housing B. Accordingly, the card tray T can be picked up with fingers or the like.

  Even when the card connector C1 of the present embodiment is provided in the inner part of the housing B having the narrow insertion hole Bh so that fingers and the like cannot be inserted, the card tray T is directly operated with fingers and the like until temporary holding. After that, the card tray T can be inserted to the contact position of the terminal (FIG. 7) using the closing operation of the lid member L. Further, the card tray T is discharged (ejected) simply by removing the lid member L from the insertion hole Bh. Therefore, according to the card connector C1 of this embodiment, it is easy to mount and take out the card tray.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the following description of the second embodiment, elements that are the same as those in the first embodiment described above are given the same reference numerals or omitted, and differences from the previous embodiments will be described. To do.

  FIG. 9 is a plan view of a card connector according to the second embodiment of the present invention.

  The card connector C2 shown in FIG. 9 is different from the card connector C1 of the first embodiment shown in FIG. 1 in the shape of the cam groove 90 provided in the cam portion 9.

  FIG. 10 is an enlarged view of the cam portion 9 shown in FIG.

  A cam groove 90 formed in the cam portion 9 shown in FIG. 10 has a structure in which two heart cam grooves are connected. The cam groove 90 is provided with a second butting section 95 and a releasing operation section in addition to the release section 81, butting section 82 and temporary holding section 83 similar to the cam groove 80 (see FIG. 2) in the first embodiment. 97. Further, the position of the terminal contact node 96 is different from the cam groove 80 (see FIG. 2) in the first embodiment. A second heart cam groove is formed by the second abutting joint 95, the terminal contact joint 96, and the release operation joint 97. The cam groove 90 is formed in a path that returns from the second butting node 95 to the terminal contact node 96 and from the terminal contact node 96 to the release node 81 via the release operation node 97.

  Both the second butting section 95 and the release operation section 97 are provided on the innermost side in the insertion direction S in the cam groove 90. In the present embodiment, the distance from the temporary holding node 83 to the second butting node 95 (release operation node 97) in the insertion direction S is the temporary holding in the card connector C1 (see FIG. 7) of the first embodiment. The distance from the node 83 to the terminal contact node 84 is longer. In the present embodiment, the distance from the temporary holding node 83 to the second butting node 95 is longer than the thickness (dimension in the insertion direction S) of the lid member L (see FIG. 7).

  The second abutting section 95 corresponds to a second abutting position where the slider 4 (see FIG. 9) pushed in the insertion direction S abuts against the temporary holding position (see FIG. 6).

  The terminal contact node 96 corresponds to the contact position reached by the slider 4 (see FIG. 9) on the way back in the take-out direction R with the release of the operation force after moving to the second abutting position.

  The release operation node 97 corresponds to the release operation position in which the slider 4 (see FIG. 9) that has reached the contact position is pushed in the insertion direction S from the contact position by receiving the operation force again.

  FIG. 11 is an enlarged view of the cam portion 9 with the slider moved to the temporary holding position.

  The position of the cam pin 7 shown in FIG. 11 is the same as the position of the cam pin 7 shown in FIG. 6 in the card connector C1 of the first embodiment. That is, the cam pin 7 shown in FIG. 11 is in a state of abutting against the temporary holding joint 83. Further, the position of the slider 4 (see FIG. 9) in this state is the same as the position of the slider 4 shown in FIG. 5 in the card connector C1 of the first embodiment. That is, the position of the slider 4 (see FIG. 9) corresponding to the temporary holding joint 83 with the cam pin 7 shown in FIG. 11 is the temporary holding position.

  The process that the cam pin 7 and the slider 4 (see FIG. 9) pass through until the cam pin 7 in the present embodiment reaches the temporary holding joint 83 shown in FIG. 11 is described in the first embodiment with reference to FIGS. It is the same as the process in. Therefore, in the second embodiment, description overlapping with the first embodiment will be omitted, and the process after reaching the temporary holding node 83 shown in FIG. 11 will be described.

  As shown in FIG. 11, when the card tray T (see FIG. 1) is pushed in the insertion direction S while the cam pin 7 is in the temporary holding joint 83, the cam pin 7 extends from the temporary holding joint 83 along the cam groove 90. Thus, it is possible to move in the insertion direction S and move to the second butting node 95.

  However, as described above, the distance from the temporary holding joint 83 to the second butting joint 95 in the insertion direction S is longer than the thickness of the lid member L (see FIG. 7), and the lid member L is the card. It is longer than the distance at which the tray T (see FIG. 7) can be pushed. Therefore, as shown in FIG. 7, when the card tray T is pushed by the lid member L that closes the insertion hole Bh, the cam pin 7 does not reach the second abutting node 95. In this case, when the lid member L (see FIG. 7) is removed and the force from the lid member L to the card tray T is released, the cam pin 7 returns to the release joint 81 and the card tray T is ejected. This operation is the same as in the first embodiment described above.

  The cam pin 7 reaches the second abutting node 95 by, for example, using a rod-shaped jig Q (see FIG. 12) to make the card tray T longer than the distance by the lid member L (see FIG. 7). This is the case of pushing in. The use of the rod-shaped jig Q as shown in FIG. 12 is a situation where, for example, the lid member L (see FIG. 7) is lost.

  FIG. 12 is a diagram illustrating a state in which the slider has moved to the terminal contact position.

  When the slider 4 is in the above-described second abutting position, when the jig Q is removed from the insertion hole Bh and the operating force is released, the slider 4 is moved by the biasing force of the biasing member 6 to the card tray T. Is pushed back in the removal direction R. At this time, the cam pin 7 moves from the second abutting node 95 along the cam groove 90 in the take-out direction R, and abuts against the terminal contact node 96 as shown in FIG. Accordingly, the slider 4 and the card tray T are held at the terminal contact positions shown in FIG. In the terminal contact position shown in FIG. 12, the contact 3 is in contact with the terminals P2 to P4 and P6 to P8. The state shown in FIG. 12 is a state in which the card J is completely attached to the card connector C2. In the present embodiment, the contact 3 contacts the terminals P2 to P4 and P6 to P8 even when the cam pin 7 is in the second butting node 95 or the release operation node 97 (see FIG. 13).

  FIG. 13 is an enlarged view of the cam portion 9 shown in FIG.

  As shown in FIG. 13, when the jig Q shown in FIG. 12 is inserted again from the insertion hole Bh and the card tray T is pushed with the cam pin 7 abutting against the terminal contact node 96, the slider 4 moves in the insertion direction S. Moving. Along with this, the cam pin 7 moves from the terminal contact node 96 along the cam groove 90 in the insertion direction S and hits the release operation node 97.

  When the jig Q (see FIG. 12) is pulled out from the insertion hole Bh (see FIG. 12) and the operating force is released in a state where it hits the release operation node 97, the slider 4 (see FIG. 12) is moved to the card tray T. (Refer to FIG. 12) As the push-back is performed in the take-out direction R, the cam pin 7 moves from the release operation joint 97 along the cam groove 90 in the take-out direction R and moves to the release joint 81. The slider 4 moves to the release position shown in FIG. That is, the card tray T (see FIG. 1) is discharged from the card connector C2.

  According to the card connector C2 of the present embodiment, if the lid member L (see FIG. 7) is used, the card tray can be easily mounted and taken out as with the card connector of the first embodiment. Further, even when the lid member L is lost, the card tray T is pushed into the terminals P2 to P4 and P6 to P8 as shown in FIG. 12 by pushing the card tray T using the jig Q (see FIG. 12). It can be held in the contact position.

  In the embodiment described above, card connectors C1 and C2 into which the card tray T on which the card J is mounted are inserted are shown as examples of the card connector according to the present invention.
