  The present invention relates to a card connector. In particular, the present invention relates to a structure of a tray type card connector in which a card is accommodated in a tray and attached to and detached from the connector.

  A memory card, which is a card-type storage device, employs a flash memory as a storage medium. A memory card is very small and consumes little electric power for reading and writing data. For example, it is widely used as a recording medium for portable information devices such as mobile phones with cameras and PDAs (Personal Digital Assistance).

  In recent years, SIM (Subscriber Identity Module) cards have become widespread as cards used in mobile phones. The SIM card is a card that can be removed from the mobile phone, and records contract information with a communication carrier. Therefore, by attaching the SIM card to a mobile phone of another manufacturing company, it is authenticated that it is a subscriber of a communication carrier, and this mobile phone can be used.

  By the way, in the connector for connecting a card as described above, the connection between the contact provided on the connector and the pad as the contact provided on the card is momentarily disconnected by vibration or impact (so-called “instantaneous interruption”). May occur.

  And the tray type card connector which is difficult to generate | occur | produce an instantaneous interruption with respect to the above malfunctions is disclosed (for example, refer patent document 1).

  The card connector according to Patent Document 1 includes a tray that can accommodate a card, a housing having a space in which the tray can move, and a plurality of contacts provided in the housing. And the connector for cards by patent document 1 provides the biasing member which contact | abuts only the card | curd accommodated in the tray in the said connector main body in the housing. Also, ribs that contact the card are provided inside the wall portion of the tray.

  Further, a tray type card connector that maintains the low profile of the connector against the above-described problems and ensures reliability in electrical contact between the pad and the contact provided on the card inserted into the connector is provided. It is disclosed (for example, see Patent Document 2).

  The card connector according to Patent Document 2 includes a tray that can store a card and a housing into which the tray that stores the card is slidably inserted. The tray is formed along both side portions of the flat portion, and has a pair of edges with one end having a substantially L-shaped cross section facing outward.

  On the other hand, the housing has a guide and a base portion. The guide is formed along both sides of the housing, and the edge of the tray is slidably inserted. The base portion has a content connected to a pad provided on the card. Furthermore, the protrusion is formed in a part of both sides | surfaces of the base part facing a guide. When the tray is inserted into the housing, the protrusion can apply pressure to the edge in the guide direction from the inside.
