Description

  The present invention relates to a card connector, and more particularly to a card connector for simultaneously mounting two types of cards in a crossing direction.

  Conventionally, a card connector for simultaneously mounting two types of cards in a crossing direction is known (see, for example, Patent Document 1). In such a card connector, the SD card connector part to which the SD card is attached and detached and the SIM card connector part from which the SIM card is attached and detached are integrally molded with resin so that the SD card contact terminal and the SIM card The contact terminal lead-out directions are arranged in directions orthogonal to each other.

Incidentally, in recent years, a memory card such as an SD card to be mounted on such a card connector has been downsized. On the other hand, electronic devices that record various data on such a memory card are also reduced in size and thickness. For this reason, further miniaturization and thinning are demanded also for a card connector mounted on such an electronic device and for mounting a memory card.
JP 2001-307801 A

  However, in the card connector for simultaneously mounting the two types of cards as described above in the crossing direction, when the miniaturization is advanced, a portion where the contact terminals for each card overlap vertically is generated. There is a possibility that the contact terminals come into contact with each other in the portion, and there is a limit to reducing the thickness.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a card connector that can be reduced in thickness by preventing contact between contact terminals even when downsized. .

The card connector according to the present invention includes a first mounting portion on which a first card can be mounted, a second mounting portion on which a second card can be mounted, and a partition wall that partitions the first mounting portion and the second mounting portion. A first contact terminal capable of contacting the contact portion of the first card; and a second contact terminal capable of contacting the contact portion of the second card, wherein the first contact terminal and the second contact terminal are provided. Is disposed opposite to the partition wall, and the first contact terminal and the second contact terminal are card connectors that directly face each other at an opening provided in the partition wall , When the first card and the second card are mounted at the same time, the second contact terminal is connected to the first contact terminal within the range of the recess provided in the contact portion of the first contact terminal. Characterized in that arranged in no contact position.

According to the card connector, since the second contact terminal is disposed within the range of the recess provided in the contact portion of the first contact terminal, the first contact terminal and the second contact terminal are close to each other. Even in this case, since the concave portions can be opposed to each other, contact between the first contact terminal and the second contact terminal can be prevented. As a result, even when the card connector is miniaturized and the first contact terminal and the second contact terminal are arranged at the overlapping position, it is possible to prevent contact between the contact terminals and reduce the thickness. .
Further, since the first contact terminal and the second contact terminal are directly opposed to each other in the opening provided in the partition wall, the first contact terminal and the second contact terminal are the second contact terminal and the second contact terminal more than the case where the first contact terminal and the second contact terminal are opposed to each other across the partition wall. Since the contact terminals can be arranged close to each other, the card connector can be made thinner.

  In the card connector, it is preferable that the second contact terminal is disposed at a position where it does not contact the first contact terminal within an installation range of a contact portion of the second card attached to the second attachment portion. In this case, since the position of the second contact terminal is adjusted within the installation range of the contact portion of the second card, the first contact is ensured with the contact portion of the second card at the second contact terminal. It is possible to prevent contact with the contact terminal.

The card connector further includes a first cover member that covers the first mounting portion and a second cover member that covers the second mounting portion, and the housing is a first for inserting the first card. A first card insertion port provided on the first side surface of the housing, and the second side surface of the housing includes the first card insertion port. 2 card insertion port and an external connection portion of the second contact terminal are provided, an external connection portion of the first contact terminal is provided on the third side surface of the housing, and the first side surface is provided on the fourth side surface of the housing. It is preferable that a connection member for electrically connecting the cover member and the second cover member is provided. In this case, the first card insertion port and the second card insertion port, and the first contact terminal and the second contact terminal are provided with a connection member on the fourth side surface of the housing where the external connection portions are not provided. Since the cover member and the second cover member are electrically connected, it is possible to ensure resistance to external noise without hindering the thinning of the card connector.

  In the card connector, the first contact terminal is in contact with the first contact terminal, and a first restricting portion that restricts the protrusion of the first card over a predetermined position on the insertion path; It is preferable that the first contact terminal is disposed so as to be sandwiched between a second restriction portion that abuts on the contact terminal and restricts the protrusion toward the second mounting portion. In this case, even when a card different from the predetermined first card is inserted into the first mounting portion and the first contact terminal moves more than when the first card is inserted, the second mounting is performed. Since the protrusion to the portion can be restricted, the contact between the first contact terminal and the second contact terminal can be prevented.

  In particular, in the card connector, the partition wall is provided with an opening at a position facing the first restricting portion so that the first attaching portion and the second attaching portion communicate with each other, and the second restricting portion is provided. Preferably, the part is the partition wall on both sides of the opening, and the first restricting part is provided integrally with the partition wall. In this case, since the opening is provided at a position facing the first restricting portion, the first restricting portion can be easily formed when the partition wall is manufactured.

  In the card connector, it is preferable that the first contact terminal has a width wider than the width of the opening. In this case, it is possible to reliably prevent the first contact terminal from protruding toward the second mounting portion side by the second restricting portion including the partition walls arranged on both sides of the opening.

  According to the present invention, since the second contact terminal is disposed within the range of the recess provided in the contact portion of the first contact terminal, the first contact terminal and the second contact terminal are close to each other. However, since these can be opposed to each other with the concave portion interposed therebetween, contact between the first contact terminal and the second contact terminal can be prevented. As a result, even when the card connector is miniaturized and the first contact terminal and the second contact terminal are arranged at the overlapping position, it is possible to prevent contact between the contact terminals and reduce the thickness. .

As shown in FIG. 14, in the connector 1 according to the present embodiment, the position of the second contact terminal 15 arranged on the foremost side is slightly more than the center of the corresponding contact pad B1 of the second card B. Adjustments are made to contact the rear position. Accordingly, it is possible to prevent contact with the first contact terminal 14 while ensuring contact with the contact pad B1 of the second card B in the second contact terminal 15.

  Further, in the connector 1 according to the present embodiment, not only the second contact terminal 15 arranged on the foremost side but also the position of the second contact terminal 15 second from the front side corresponds to the corresponding second card B. It adjusts so that it may contact the position of the back side slightly from the center of the contact pad B1. This is for reliably preventing contact between the tip of the first contact terminal 14 and the second contact terminal 15. Since the two second contact terminals 15 arranged on the rear side are not likely to come into contact with the first contact terminal 14, the contact pads B1 of the corresponding second card B are similar to the known contact terminals. It is in contact with the center.

  By the way, in the connector 1 which concerns on this Embodiment, when the predetermined 1st card | curd A is mounted | worn, the contact with the 1st contact terminal 14 and the 2nd contact terminal 15 is prevented. However, even when a card different from the first card A is erroneously inserted, it is necessary to prevent contact between the first contact terminal 14 and the second contact terminal 15. For this reason, in the connector 1 which concerns on this Embodiment, when a different card | curd is inserted, it regulates so that the 1st contact terminal 14 may not protrude over the partition wall 9 to the 2nd mounting part 8 side.

  Moreover, in the connector 1 which concerns on this Embodiment, the 1st contact terminal 14 is fixed in the front side edge part vicinity of the connector 1, and the front-end | tip part of the back side is made into the free end. For this reason, when the movement of the rear end portion is not limited, the first contact terminal 14 protrudes on the insertion path of the first card A, and the front end portion may be buckled as the first card A is inserted. is there. For this reason, in the connector 1 which concerns on this Embodiment, it controls so that the 1st contact terminal 14 may not protrude beyond a fixed position on the insertion path | route of the 1st card | curd A. FIG. Note that the fixed position on the insertion path of the first card A can be, for example, a position where the tip of the first contact terminal 14 can avoid buckling as the card is inserted into the first mounting portion 7.

  15 to FIG. 15A and FIG. 15B to FIG. 15C to FIG. 15B to FIG. 15B to FIG. 17 will be used for explanation. FIG. 15 is a perspective view showing the housing 2 of the connector 1 according to the present embodiment from the front side (first contact terminal 14 side). 16 and 17 are enlarged views of the vicinity of the tip of the first contact terminal 14 shown in FIG. In FIG. 16, the first contact terminal 14 is omitted.

  As shown in FIG. 15, the partition wall 9 has a first restriction that restricts the tip of the first contact terminal 14 from projecting onto the insertion path of the first card A in the vicinity of the tip of the first contact terminal 14. A restricting portion 93 and a second restricting portion 94 that restricts the distal end portion of the first contact terminal 14 from protruding toward the second mounting portion 8 are provided. The first restricting portion 93 restricts the upward movement of the first contact terminal 14 above a certain position, and the second restricting portion 94 is directed downward below the certain position of the first contact terminal 14. It restricts movement.

  As shown in FIG. 16, the 1st control part 93 is integrally provided in the upper surface part vicinity of the partition wall 9, and is comprised as a protrusion piece which protrudes ahead. As shown in FIG. 17, the first restricting portion 93 abuts on the upper surface of the wide portion 144 provided at the distal end portion of the first contact terminal 14 when the first card A is not mounted, The terminal 14 is restricted from protruding beyond a certain position on the insertion path of the first card A.

  As shown in FIG. 16, the partition wall 9 has an opening 95 at a position facing the first restricting portion 93. The first mounting part 7 and the second mounting part 8 are communicated with each other through the opening 95. The second restricting portion 94 is configured by a partition wall 9 on the side of the opening 95. As shown in FIG. 17, the wide portion 144 provided at the tip of the first contact terminal 14 is set wider than the opening 95. Even when a card different from the planned first card A is inserted, the second restricting portion 94 contacts the lower surface of the wide portion 144 (more specifically, a part of the lower surface on the side side). The protrusion of the first contact terminal 14 toward the second mounting portion 8 is restricted. The opening 95 is used when the projecting piece as the first restricting portion 93 is molded in the housing 2. Thus, by providing the opening 95 at a position facing the first restricting portion 93, the first restricting portion 93 can be easily formed when the partition wall 9 is manufactured.

  As described above, in the connector 1 according to the present embodiment, the first contact terminal 14 is disposed at a position sandwiched between the first restricting portion 93 and the second restricting portion 94, so that the first predetermined terminal is set. Even when a card different from the card A is inserted into the first mounting portion 7 and the first contact terminal 14 moves downwardly more than when the first card A is inserted, it protrudes into the second mounting portion 8. Therefore, it is possible to prevent contact between the first contact terminal 14 and the second contact terminal 15.

  In particular, in this case, the partition wall 9 disposed on both sides of the opening 95 constitutes the second restricting portion 94, and the wide portion 144 of the first contact terminal 14 having a width wider than the opening 95 is brought into contact with the second restricting portion 94. I am letting. Thereby, it is possible to reliably prevent the first contact terminal 14 from protruding toward the second mounting portion 8.

  In addition, this invention is not limited to the said embodiment, It can change and implement variously. In the above-described embodiment, the size, shape, and the like illustrated in the accompanying drawings are not limited to this, and can be appropriately changed within a range in which the effect of the present invention is exhibited. In addition, various modifications can be made without departing from the scope of the object of the present invention.

  For example, in the above embodiment, when the first mounting portion 7 is configured to restrict the first contact terminal 14 from protruding into the second mounting portion 8 when a card different from the first card A is inserted into the first mounting portion 7. However, in addition to this configuration, the second contact terminal 15 may be configured to restrict the first mounting portion 7 from protruding. In this case, even when a card different from the second card B is inserted into the second mounting portion 8, the protrusion of the second contact terminal 15 toward the first mounting portion 7 can be restricted. The contact between the first contact terminal 14 and the second contact terminal 15 can be prevented.
