Description

  The present invention relates to a tray-type card connector, and more specifically, a tray that is disposed inside a lid of a housing of an information device having a lid, and that can accommodate an IC card, and a tray that accommodates an IC card. It is related with the tray-type card connector provided with the connector main-body part which hold | maintains slidably in the state which the said cover opened.

  In recent years, information devices such as mobile phones are often provided with card connectors to which IC cards can be attached. There are various specifications for IC cards. For example, in a mobile phone, a subscriber authentication module for authenticating that a mobile phone manufacturer and a seller are subscribers of the communication carrier when the mobile phone manufacturer and seller are different. An IC card called (SIM) is used.

  Examples of the IC card attachment / detachment structure in the card connector include a push-push type (for example, see Patent Document 1 below) and a tray type (for example, see Patent Documents 2 and 3 below). In the push-push type, when the IC card is pushed into the card connector, the IC card is attached to the card connector, and when the IC card attached to the card connector is pushed again, the attached state is released and the IC card is taken out from the card connector. It is a method (structure) that can be used.

  In the tray type, a slidable tray is provided in the connector body, and an IC card is placed on the tray slid from the connector body, and the IC card is pushed into the connector body to insert the IC card. This is a system (structure) in which an IC card can be taken out from the card connector by attaching the card to the card connector and pulling out the tray on which the IC card is installed from the connector body.

  If the user's operability is emphasized, the push-push type in which the IC card can be attached to and detached from the card connector only by pushing the IC card is superior. On the other hand, in the case of the push-push type, the structure for realizing it is complicated, and the size of the entire card connector becomes large. Therefore, it is difficult to reduce the size of the entire information device (for example, a mobile phone). There is a drawback of becoming.

  On the other hand, the tray type has the advantage that the structure for realizing it is relatively simple, the card connector as a whole can be easily downsized, and the information equipment as a whole can be easily downsized. ing. In addition, the tray type has an advantage that it is excellent in reliability of electrical contact against an external force such as an impact. On the other hand, when the IC card is attached to or detached from the card connector, it is necessary to put in and out the tray with respect to the connector main body, so that there is a disadvantage that the user's operability is inferior compared with the push-push type.
