Connector for card

Description

Connector for Cards {CONNECTOR FOR CARD}

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a card connector, and more particularly, to a card connector for simultaneously mounting two cards in a direction crossing each other.

Conventionally, the card connector which mounts two types of cards simultaneously to cross | intersect is known (for example, refer patent document 1). In such a card connector, the SD card connector portion to which the SD card is attached and detached and the SIM card connector portion to which the SIM card is detached are molded up and down integrally with resin, and the direction in which the SD card contact terminal and the SIM card contact terminal are drawn out. Are arranged in directions perpendicular to each other.

By the way, in recent years, memory cards, such as an SD card mounted in such a card connector, have become small. On the other hand, electronic devices for recording various data and the like on such a memory card are also downsized and thinned. For this reason, the further miniaturization and thickness reduction are requested | required also in the card connector mounted in such an electronic device and mounting a memory card.

Patent Document 1: Japanese Patent Application Laid-Open No. 2001-307801

However, in the card connector which simultaneously mounts two types of cards as described above in the intersecting direction, if the miniaturization thereof proceeds, a part where each card contact terminal overlaps vertically occurs, and the contact is made in the part. There was a possibility that the terminals could contact each other, and the thickness was limited.

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

The card connector of the present invention includes a housing having a first mounting portion for mounting a first card, a second mounting portion for mounting a second card, and a partition wall for separating the first mounting portion and the second mounting portion; And 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 connected to each other. A connector for a card disposed opposite to a partition wall, wherein the second contact terminal is disposed within the range of a recess formed in a contact portion of the first contact terminal when the first card and the second card are mounted at the same time; It is characterized by arrange | positioning in the position which is not in contact with a contact terminal.

According to the said card connector, since a 2nd contact terminal is arrange | positioned within the range of the recessed part formed in the contact part of a 1st contact terminal, even if a 1st contact terminal and a 2nd contact terminal approach each other, Since these parts can be replaced with each other, contact between the first contact terminal and the second contact terminal can be prevented. As a result, even when the connector for the card is miniaturized and arranged at a position where the first contact terminal and the second contact terminal overlap, the contact terminals can be prevented from contacting and the thickness can be reduced.

In the card connector, it is preferable to arrange the second contact terminal at a position not in contact with the first contact terminal within the installation range of the contact portion of the second card mounted on the second mounting 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 terminal is secured while ensuring contact with the contact portion of the second card at the second contact terminal. The contact can be prevented.

In the card connector, it is preferable that the first contact terminal and the second contact terminal directly face each other in an opening formed in the partition wall. In this case, the first contact terminal and the second contact terminal can be arranged closer to each other than the case where the partition wall is opposed to each other, whereby the connector for the card can be made thinner.

The card connector includes a first cover member covering the first mounting portion, a second cover member covering the second mounting portion, and the housing includes a first card insertion hole for inserting the first card; And a second card insertion hole for inserting the second card, wherein the first card insertion hole is formed on a first side of the housing, and the second card insertion hole and the second contact terminal are formed on a second side of the housing. An external connection portion is formed, an external connection portion of the first contact terminal is formed on a third side surface of the housing, and a connection member electrically connecting the first cover member and the second cover member to a fourth side surface of the housing. It is preferable that is formed. In this case, the first cover member and the first cover member and the first cover member and the second card insertion port, and the fourth side surface of the housing in which the external connection portions of the first contact terminal and the second contact terminal are not formed are formed. Since the two cover members are electrically connected, resistance to foreign noise can be ensured without hindering the thinning of the connector for the card.

In the card connector, the first contact terminal includes a first restricting portion that contacts the first contact terminal and restricts protrusion of a predetermined position or more onto the insertion path of the first card; It is preferable to be interposed between the 2nd restriction | restoration parts which contact | connect a contact terminal and restrict | limit the protrusion to the said 2nd attachment part side. In this case, even if a card different from the predetermined first card is inserted into the first mounting portion and the first contact terminal moves larger than when the first card is inserted, it can be restricted from protruding to the second mounting portion. Therefore, the contact between the first contact terminal and the second contact terminal can be prevented.

Particularly, in the card connector, an opening is formed in the partition wall so as to face the first restricting portion so that the first attaching portion and the second attaching portion communicate with each other, and the second restricting portion of the connector It is preferable that it is the said partition wall of both sides, and the said 1st control part is integrally formed with the said partition wall. In this case, since the opening is formed at a position facing the first restricting portion, the first restricting portion can be easily formed at the time of manufacturing the partition wall.

In the card connector, the first contact terminal preferably has a width wider than the width of the opening. In this case, it is possible to reliably prevent the projection of the first contact terminal from the side of the second attachment portion by the second restricting portion formed of partition walls disposed on both sides of the opening portion.

According to the present invention, since the second contact terminal is disposed within the concave portion formed in the contact portion of the first contact terminal, even when the first contact terminal and the second contact terminal approach each other, the second contact terminal is disposed between the concave portions. Since it can replace, the contact of a 1st contact terminal and a 2nd contact terminal can be prevented. As a result, even when the connector for the card is miniaturized and arranged at a position where the first contact terminal and the second contact terminal overlap, the contact terminals can be prevented from contacting and the thickness can be reduced.

In particular, in this case, the first contact terminal 14 constitutes the second restricting portion 94 in the partition wall 9 disposed on both sides of the opening 95, and has a wider width than the opening 95. The wide portion 144 is in contact with each other. This makes it possible to reliably prevent protrusion of the first contact terminal 14 on the second mounting portion 8 side.

In addition, this invention is not limited to the said embodiment, It can variously change and implement. In the above embodiment, the size, shape, and the like shown in the accompanying drawings are not limited to this, and can be appropriately changed within the range in which the effects of the present invention are exhibited. In addition, unless it deviates from the range of the objective of this invention, it can change suitably and can implement.

For example, in the above embodiment, the first contact terminal 14 protrudes from the second mounting portion 8 when a card different from the first card A is inserted into the first mounting portion 7. Although the case where it is provided with the structure mentioned above was demonstrated, in addition to this structure, the 2nd contact terminal 15 may be provided with the structure which restrict | limits that the 1st mounting part 7 protrudes. 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 side can be restricted. It is possible to prevent contact between the first contact terminal 14 and the second contact terminal 15.
