Two-tiered plug for two chip cards
First Claim
1. An electronic device for use with first and second data carriers comprising:
- a first frontal side having an opening;
a plurality of data carrier devices in said opening stacked over one another with respective front surfaces offset, said data carrier devices each comprising at least one integrated semiconductor circuit and a plurality of contact surfaces located adjacent one another in a row on a surface of the data carrier;
two spatially offset rows of contact springs lying next to one another in a terminal side of the electronic device opposite the opening having ends at the terminal side respectively fashioned as plug terminals;
wherein resilient ends of contact springs of a first, lower row contact as disposed to make contact with surfaces of an inserted first, lower data carrier from above; and
wherein spring ends of a second, upper row, which is offset upwards by substantially a height of a data carrier in relation to the spring ends of the first row, are offset in the insertion direction from the spring ends of the first row and are disposed to make contact with contact surfaces of an inserted second, upper data carrier from above.

Abstract
An electronic device has an opening for up to two data carrier devices or, respectively, chip cards with row-type contact surfaces positioned alongside one another. The devices or, cards are stackable over one another in offset fashion. In a region of the terminal side lying opposite the plug opening it comprises two rows of contact springs lying next to one another, said rows being spatially offset upwards by the height of a card, and also offset in the insertion direction in a manner corresponding to the card offset. The resilient ends at the plug side of these contact springs respectively contact the contact surfaces of inserted data carriers from above.
