Abstract

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.

First claim

The invention claimed is:

1. A device, comprising:
a support member;
a plurality of card contacts physically coupled to the support member; and
an encasing member including:
an elevated portion that is spaced from and directly overlies the plurality of card contacts;
first and second side portions, the support member being positioned between the first and second side portions;
mounting members extending from the first and second side portions and towards a circuit board, the mounting members mounting the encasing member to the circuit board;
first and second engaging portions directly attached to the first and second side portions, respectively, the first and second engaging portions affixing the encasing member to the support member, the support member being sandwiched between the elevated portion and the first and second engaging portions; and
a heat sink including a first portion physically coupled to the elevated portion and a second portion physically coupled to the first portion, the second portion directly overlying the plurality of card contacts, the second portion including a plurality of sides that are spaced and detached from the elevated portion.

2. The device of claim 1 wherein the elevated portion and the heat sink are a single contiguous piece.

3. The device of claim 1 wherein the first portion extends in a first direction and the second portion extends in a second direction that is transverse to the first direction.

4. The device of claim 1 wherein the elevated portion includes an aperture that directly overlies the second portion.

5. The device of claim 1 wherein the encasing member, including the elevated portion and the heat sink, are made of a conductive material.

6. The device of claim 1 wherein the encasing member includes sidewalls, and the support member is positioned between the sidewalls.

7. The device of claim 1 wherein the second portion has a rectangular shape.
