DUAL PURPOSE PRESS-BAR AND HEAT SINK FOR HIGH DATA TRANSFER INTEGRATED CIRCUIT CARD READER

摘要

Various embodiments provide a dual purpose press-bar and heat sink for an integrated circuit card (ICC) reader. The dual purpose press-bar and heat sink provides two functions. First, the dual purpose press-bar and heat sink conducts and dissipates internal heat generated by a high data transfer ICC inserted in to the ICC reader. Second, the dual purpose press-bar and heat sink ensures that contact pads of the high data transfer ICC create reliable electrical connections with ICC contacts of the ICC reader. As such, the dual purpose press-bar and heat sink simultaneously dissipates heat from a high data transfer ICC and ensures that a high data transfer ICC maintains proper electrical connections with ICC contacts of an ICC reader.

主权项

1. A card reader device, comprising:
a support member; a plurality of card contacts coupled to and extending from the support member, each of the plurality of card contacts being in electrical contact with a contact pad on a first surface of a card; a circuit board in electrical contact with the card contacts, the plurality of card contacts being coupled to the circuit board by the support member; and an encasing member including:
first and second side portions affixed to the support member;an elevated portion attached to the first and second side portions, the elevated portion substantially covering the support member and the plurality of card contacts, the elevated portion being spaced from a second surface, opposite to the first surface, of the card;a heat sink overlaying the plurality of card contacts, the heat sink projecting from the elevated portion towards the support member and the plurality of card contacts, the heat sink being in physical contact with the second surface of the cardsfirst and second openings in the elevated portion, the first opening being positioned lateral to a first side of the heat sink, the second opening bein positioned lateral to a second side, opposite to the first side, of the heat sink; andfirst and second plurality of air flow apertures in the elevated portion, the first plurality of air flow apertures being positioned lateral to a third side of the heat sink, the second plurality of air flow apertures being positioned lateral to a fourth side, opposite to the third side, of the heat sink, the first side portion bein spaced from the third side of the heat sink by the first plurality of air flow apertures, the second side portion being spaced from the fourth side of the heat sink by the second plurality of air flow apertures, the first and second openings and the first and second plurality of air flow apertures exposing the second surface of the card to provide an air flow channel that flows between the first and second plurality of air flow apertures, adjacent to the heat sink, and on the second surface of the card.
