  FIGS. 30, 31, and 32 of the present application correspond to FIGS. 4, 3, and 6 of Patent Document 1. 33 (A) to 33 (C) of the present application correspond to FIGS. 9 to 11 of Patent Document 1.

  Referring to FIGS. 30 to 32, a card connector (hereinafter simply referred to as a connector) 9 according to the related art includes a plate-shaped housing 91 and a cover plate 92. Further, the connector 9 includes a plurality of first contacts 93 and a plurality of second contacts 94.

  Referring to FIG. 30 or FIG. 32, the housing 91 has a first recess 911 and a second recess 912. The first recess 911 and the second recess 912 have a step. The bottom surface of the second recess 912 is higher than the bottom surface of the first recess 911. A plurality of first contacts 93 are arranged in the first recess 911. A plurality of second contacts 94 are arranged in the second recess 912.

  Referring to FIGS. 30 to 32, the cover plate 92 covers the first recess 911 and the second recess 912. Then, any one of a first-type card D, a second-type card S, and a second-type card M, which will be described later, can be inserted into the connector 9 from the first recess 911 side (FIG. 33). reference).

  Referring to FIGS. 30 to 32, a pair of leaf spring-shaped card guides 95a and 95b are arranged at both ends of the first concave portion 911. The pair of card guides 95a and 95b can be guided by contacting both side surfaces of the card inserted into the first recess 911. Further, the pair of card guides 95a and 95b can press the bottom surface of the card toward the cover plate 92 (see FIG. 31). A card recognition switch (not shown) is arranged near the card guide 95a. When the card is inserted into the first recess 911, the switch for recognizing the card can be operated in conjunction with the operation of the one card guide 95a.

  Referring to FIG. 30 or FIG. 32, the connector 9 includes an ejection mechanism J. The eject mechanism J can operate to stop the card when the card is inserted into the first recess 911 or the second recess 912, and can eject the card when the stopped card is pressed. The eject mechanism J that operates in this manner is also called a push-push mechanism.

  Referring to FIG. 30 or FIG. 32, the ejection mechanism J includes a plate-shaped slide member J1, a compression coil spring J2, and a guide rod J3. The slide member J1 is connected to the housing 91 so as to be able to advance and retreat in a direction parallel to the card insertion / removal direction. The slide member J1 has a heart-shaped cam groove Jd formed on one surface (see FIG. 32).

  Referring to FIG. 30 or FIG. 32, the compression coil spring J2 is held by the housing 91. Further, the compression coil spring J2 biases the slide member J1 in a direction in which the card is ejected. One end of the guide bar J3 is connected to a heart-shaped cam groove Jd. The other end of the guide bar J3 is rotatably connected to the housing 91.

  Referring to FIG. 32, one end of the guide bar J3 is located at the starting point of the heart-shaped cam groove Jd. When the card is inserted into the first concave portion 911 from the state shown in FIG. 32 and the slide member J1 is moved to the rear side of the housing 91 against the urging force of the compression coil spring J2, one end of the guide bar J3 becomes Move to the branch point of the heart-shaped cam groove Jd. Then, when one end of the guide bar J3 reaches the branch point of the heart-shaped cam groove Jd, the guide bar J3 can lock the slide member J1 and can define the stop position of the card.

  Referring to FIG. 32, once the card is pushed from the state where one end of the guide rod J3 is located at the branch point of the heart-shaped cam groove Jd, one end of the guide rod J3 is moved to the position of the heart-shaped cam groove Jd. It is released from the branch point and relatively moves to the return stroke of the heart-shaped cam groove Jd. The card can be ejected by the compression coil spring J2 moving the slide member J1 to the opening side of the housing 91.

  Next, the configuration of a card applied to the connector 9 shown in FIGS. 30 to 32 will be described. The first type card D shown in FIG. 33A is, for example, a small memory card called an MS duo card.

  Referring to FIG. 33A, the card D has a predetermined outer width Dw and a predetermined thickness Dt. Further, the card D has a notch Da for preventing erroneous insertion at a corner. Further, the card D has a plurality of connection terminals Dc arranged at the end on the insertion side. The connection terminal Dc can be electrically connected to the second contact 94 (see FIGS. 30 to 32).

  The second type card S shown in FIG. 33B is, for example, a memory card called an SD card. Referring to FIG. 33B, the card S has a predetermined outer width Sw and a predetermined thickness St. In the card S, a plurality of connection terminals Sc are arranged at the end on the insertion side. The connection terminal Sc can be electrically connected to the first contact 93 (see FIGS. 30 to 32).

  33 (A) and FIG. 33 (B), the depth dimension of the card D is longer than that of the card S. On the other hand, the outer width Sw of the card S is larger than the outer width Dw of the card D. The thickness St of the card S is larger than the thickness Dt of the card D. That is, the relationship of the external width Sw> the external width Dw and the thickness St> the thickness Dt is satisfied.

  The third type card M shown in FIG. 33C is, for example, a memory card called a mini SD card. Referring to FIG. 33C, the card M has a predetermined outer width Mw and a predetermined thickness Mt. The card M has a pair of notches Ma and Mb formed on both side surfaces on one end side. Further, the card M has a plurality of connection terminals Mc arranged at the end on the insertion side. The connection terminal Mc can be electrically connected to the first contact 93 (see FIGS. 30 to 32).

  33 (A), FIG. 33 (B), and FIG. 33 (C), the depth dimension of the card M is substantially the same as that of the card S. On the other hand, the outer width Mw of the card M is the same as the outer width Dw of the card D. The thickness Mt of the card M is the same as the thickness Dt of the card D. In other words, the relationship is such that the outer width Sw> the outer width Dw = the outer width Mw, and the thickness St> the thickness Dt = the thickness Mt.

  Referring to FIGS. 30 to 33, card D passes through first recess 911 and is inserted into second recess 912, so that card D does not come into contact with first contact 93, and connection terminal Dc Can contact the second contact 94. In addition, when the card S is inserted into the first concave portion 911, the connection terminal Sc can contact the first contact 93.

  On the other hand, referring to FIG. 30 to FIG. 33, the card M has the relationship of the outer width Dw = the outer width Mw, and the thickness Dt = the thickness Mt, so the card M is inserted into the first recess 911. However, it was difficult to make the connection terminal Mc surely contact the first contact 93. That is, it is difficult to press the connection terminal Mc toward the contact of the first contact 93.

  Therefore, the connector 9 is formed by using an adapter plate (not shown) having the same width as the outer width Sw of the card S and a predetermined thickness so as to have the same thickness as the thickness St of the card S. By holding M detachably, the connection terminal Mc of the card M with the adapter plate inserted into the first recess 911 is surely brought into contact with the first contact 93. As described above, the connector 9 can share a plurality of types of cards having different external dimensions or thicknesses and different arrangements of connection terminals.

  In recent years, a UHS-I compliant SD memory card or a UHS-II compliant SD memory card with improved memory transfer speed has appeared. It is said that a UHS-II compatible SD memory card can achieve a transfer rate that is approximately three times the transfer rate of a UHS-I compatible SD memory card. Hereinafter, the UHS-I compatible SD memory card is referred to as a first card, and the UHS-II compatible SD memory card is referred to as a second card.

  In recent digital cameras, high-speed continuous shooting using an electronic shutter is possible. For this reason, a digital camera compatible with high-speed continuous shooting has two types of SD (Secure Digital) card for normal imaging and an XQD (registered trademark) card with a high writing speed for high-speed continuous shooting that can be inserted separately. It has a card connector. For example, these card connectors are mounted on both sides of a printed board with a printed board in between.

  The SD card and the XQD card have different outer shapes and thicknesses. The SD card has a smaller outer shape and a smaller thickness than the XQD card. A card connector capable of mounting various types of cards having different shapes and thicknesses on one card connector is disclosed. Hereinafter, the XQD card is referred to as a third card.

  By the way, there is a demand for a card connector that can share the first card, the second card, and the third card. The first card and the second card have the same rectangular outer dimensions and the same thickness. The first card and the second card have the same arrangement of a plurality of first connection terminals formed at the end on the insertion side. On the other hand, the second card is different from the first card in that a plurality of second connection terminals are arranged after the plurality of first connection terminals.

  On the other hand, the third card has a rectangular outer size larger than the outer size of the first card or the second card. The third card has a thickness greater than the thickness of the first card or the second card. Further, the third card has a plurality of third connection terminals arranged inside a slot opened on one end surface.

  As a substance, the first card has a plurality of first connection terminals arranged on the bottom surface of the first groove recessed from the bottom surface. On the other hand, the second card has a plurality of first connection terminals and a plurality of second connection terminals arranged on the bottom surface of the second groove recessed from the bottom surface. That is, the length from the edge of the first groove is shorter than the length from the edge of the second groove.

  As shown in FIGS. 30 to 32, the first card that can contact the first connection terminal and the second contact that can contact the second connection terminal are disposed on the bottom surface of the recess of the housing, so that the second card can be mounted on the housing. The second card can be electrically connected to the first and second contacts by inserting the second card into the recess. On the other hand, when the first card is inserted into the concave portion of the housing, there is a concern that the step of the first groove abuts on the second contact and damages the second contact.

  A first card or a second card having the same outer dimensions and thickness, but having a partially different arrangement of connection terminals, and an outer dimension larger than the outer dimensions of the first card or the second card; A card connector having a thickness greater than the thickness of the second card and being able to share a third card in which a plurality of connection terminals are arranged inside a slot opened on one end surface, without having to worry about damaging contacts. There is a need for a card connector. And the above may be said to be an object of the present invention.

  The present invention has been made in view of such a problem, and is a card connector that can share three types of cards having different external dimensions, thicknesses, and arrangements of connection terminals, and damages contacts. An object of the present invention is to provide a card connector free from worry.

  The present inventors have provided a plate-shaped housing having a concave portion into which a third card can be inserted, an adapter plate having substantially the same width as the third card and substantially the same thickness as the third card. The first card or the second card is mounted on the adapter plate and can be inserted into the recess, so that the first card can be shared with the third card and can be connected to the first connection terminal of the first card. When a first insulating block is provided at an intermediate portion of the first contact, a second insulating block is provided at an intermediate portion of the second contact which can be connected to the second connection terminal of the second card, and the third card is inserted into the recess of the housing. The first contact and the second contact contact the third card by tipping the first contact and the second contact with the leading edge of the third card contacting the first insulating block and the second insulating block. Trouble When the first card having the first groove at the end is inserted into the recess of the housing, the leading edge of the first card comes into contact with the second insulating block, and the second contact is tilted. When it is difficult to contact the first card and the second card having the second groove at the end is inserted into the recess of the housing, the second insulating block does not tilt the two contacts, and the second contacts are connected to the second connection. We thought that we could contact the terminals, and based on this we came to invent the following new card connector.

  (1) A rectangular first card in which a plurality of first connection terminals are arranged on the bottom surface of a first groove recessed from the bottom surface of one end, the outer dimensions and thickness of the first card are the same as those of the first card; A rectangular second card in which a plurality of the first connection terminals and a plurality of the second connection terminals are arranged on a bottom surface of a second groove recessed from a bottom surface of an end, and an outer shape larger than the first card or the second card; A card connector having a size and a thickness, wherein a third card in which a plurality of third connection terminals are arranged inside a slot opened on one end surface can be used in common, wherein a concave portion into which the third card can be inserted, A plate-shaped housing having a projection protruding toward the opening of the recess and being insertable into the slot; a cover plate covering the recess of the housing; a width substantially equal to the width of the third card; Approximately the same as the thickness of the third card A rectangular adapter plate which is insertable into the recess when the first card or the second card is mounted, and which is disposed on the back side of the recess of the housing, A plurality of first contacts capable of contacting the first connection terminal in a state where the second card is mounted on the adapter plate, and A plurality of second contacts capable of contacting a second connection terminal, and a plurality of third contacts arranged on the protruding piece and capable of contacting the third connection terminal, wherein the first contact is the first groove or In a state where the third card is inserted into the recess, the first contact is formed on a tiltable first insulating block and a distal end portion, and the first contact is formed in the middle portion so as to pass through the second groove. Card And a first contact that is freely contactable with the first connection terminal when the adapter plate is inserted into the recess, wherein the second contact is intermediately disposed so as to be able to pass through the first groove or the second groove. In the state where the third card is inserted into the recess, the second contact is formed on a tiltable second insulating block and a tip portion, and the second card and the adapter plate are inserted into the recess. When the adapter plate is inserted into the recess while the first card is mounted on the adapter plate, the first card includes the second card. The second contact is separated from the bottom of the first card by tilting the second contact by contacting the bottom surface of the second insulating block with the second insulating block, and the second card is mounted on the adapter plate. , Upon insertion of the serial adapter plate in the recess, the second insulating block passes without contacting the bottom surface of the second groove, the second contact is in contact with the second connecting terminal, the card connector.

  (2) The second connection terminal includes a plurality of pairs of signal terminals, and ground terminals disposed on both sides of the pair of signal terminals, and the second contact includes the pair of signal terminals. The card connector according to (1), further comprising: a signal contact that can freely contact the ground terminal; and a ground contact that can freely contact the ground terminal.

  (3) The plurality of second contacts are made of a conductive metal plate obtained by forming a development plate, and a central portion of the metal plate is molded to form the housing, and the signal contact and the ground contact are formed. (2), the connector for a card according to (2).

  (4) The card connector according to any one of (1) to (3), further comprising an eject mechanism capable of ejecting the third card or the adapter plate from the recess.

  (5) The first card includes a UHS-I compatible SD memory card, and the second card includes a UHS-II compatible SD memory card, according to any one of (1) to (4). Card connector.

  (6) The card connector according to any one of (1) to (5), wherein the third card includes an XQD card.

  In the card connector according to the present invention, the first contact can be formed by tilting the first insulating block in the middle of the first contact, and the second contact can be formed by tilting the second insulating block in the middle of the second contact. When the third card is inserted into the recess of the housing, the first contact and the second contact are tilted to make it difficult for the first contact and the second contact to contact the third card. When inserted into the recess, the bottom surface of the first card contacts the second insulating block to tilt the second contact, making it difficult for the second contact to contact the first card. There is no need to worry about damaging the contacts.
