Description

Card connector with extraction function

technical field

The present invention relates to a card connector with a take-out function, which is used to connect a card such as an IC card on a substrate, and which can be taken out with a simple operation.

Background technique

Hitherto, among such card connectors, a card connector with a removal function is known in which a card such as an IC card or a card-shaped member such as a card tray accommodating the card can be taken out from a housing by operating a push rod (for example, Patent Document 1).

For example, as shown in FIG. 10 , the card connector with the extraction function has a push-out arm 101 rotatably supported on the inner side of the housing 100 in the direction of card insertion and removal. The end portion of the card tray 101 is rotated, and the other end side 103 of the arm is used to push out the inner edge of the card tray 104 in the ejection direction.
