Description

  The present invention relates to a card connector. In particular, the present invention relates to a connector suitable for connecting a subscriber identity module (SIM) card.

  When the mobile phone terminal manufacturer and seller are different from the telecommunications carrier, an IC card called a subscriber authentication module (hereinafter referred to as a SIM) is used to authenticate the subscriber of the telecommunications carrier.

  For example, Patent Document 1 discloses a structure of a connector provided on the back surface of a mobile phone terminal main body (see Patent Document 1 and FIG. 1).

  The structure of such a connector protruded from both side surfaces inserted into a contact base having a spring property that contacts the electrode of the SIM card or the IC card, a contact base having an opposing guide, and a guide formed on the contact base. It has a tray with guide pins on both sides.

Here, in the structure described in Patent Document 1, considering a state in which a SIM card (IC card) is accommodated in a tray and a guide pin is inserted along the guide, the contact terminal incorporated in the contact base is an IC. Applying force to push up the tray plane from the inside through the card.
JP-A-8-87582

  When this force is small, there is a risk that the “raggedness” of the IC card accommodated will increase and the contact between the IC card terminal and the contact terminal will become unstable. On the other hand, when the force with which the contact terminal pushes up the tray plane from the inside through the IC card is large, the tray plane is curved outwardly.

  Further, when the force for pushing up the tray plane is large, the force applied to the guide pins protruding from both side surfaces of the tray is also large. For this reason, in order to avoid breakage of the guide pins, it is necessary to increase the diameter of the guide pins. In such a case, it is necessary to increase the thickness of the tray plane.

  In any of the above cases, the thickness of the card connector is increased in a state where the IC card is accommodated. On the other hand, it is preferred by consumers to make the mobile phone terminal thinner to make it easier to carry.

  Therefore, in the invention described in Patent Document 1, it is difficult to meet the demands of such consumers.

  Accordingly, an object of the present invention is to provide a simpler configuration that can reduce the height of a card connector and reliably contact the terminal of an IC card with a contact terminal.

A first aspect for achieving the object of the present invention is a card connector having a tray capable of accommodating an IC card, and a main body portion into which the tray accommodating the IC card is slidably inserted. And
The tray has a flat surface portion and an edge portion formed on the flat surface portion along both side portions of the flat surface portion, with a substantially L-shaped cross section and one end of the substantially L-shaped surface directed outward. ,
The main body has a spring-like guide that is formed along both sides of the tray and has a substantially L-shaped end that can be slid into the edge of the tray, and an electrode that is electrically connected to the electrode of the IC card. Having a base portion on which contact elements are formed;
Further, when the tray is slid and inserted into the main body on at least a part of both side surfaces of the base portion facing the guide, the edge formed on the tray is pressed from the inside toward the guide. The protrusion to give is formed.

The second aspect of the present invention that achieves the object of the present invention is a card connector comprising a tray capable of accommodating an IC card and a main body portion into which the tray accommodating the IC card is slidably inserted. The tray includes a flat portion and an edge formed on the flat portion along both side portions of the flat portion, the cross-section being substantially L-shaped and one end of the substantially L-shaped facing outward. Part
The main body is electrically connected to a guide formed along both sides of the main body so that one end of the substantially L-shaped edge of the tray is slidable and an electrode of the IC card. It has a base part on which spring contact elements are formed,
Further, the width between both side portions of the base portion is formed larger than the interval between the edge portions formed along the both side portions of the flat surface portion, whereby when the tray is slid into the main body portion, The edge formed on the tray is pressed by the both sides of the base portion in the guide direction from the inside.

  Further, in the above, the flat portion of the tray is formed in the tray when the tray accommodates the IC card and the substantially L-shaped end of the edge portion is slid into the guide of the main body portion. The IC card has a thickness that can be deformed so as to apply a pressing force in the direction of the spring contact element formed on the base portion on which the spring contact element is formed by pressing force applied to the inside of the edge portion. Preferably, it is formed.

  Further, in the above, inclined portions for guiding the insertion of the tray may be formed at the end portions of the both sides of the base portion where the tray is inserted.

  The solution means of the present invention makes it possible to reduce the height of the card connector and to ensure the contact between the IC card terminal and the contact terminal.
