Abstract

A memory card reader body includes proposed, on an internal face, a receiving recess to receive a memory card connector. The receiving recess has electrically conductive tracks forming a protective mesh for the memory card connector. The conductive tracks are such that they also extend on an external face of the memory card reader body through vias passing through the internal and external faces.

First claim

The invention claimed is:

1. A memory card reader body comprising:
an internal face and an external face, wherein the internal face and the external face form opposing sides of the memory card reader body;
a receiving recess formed on the internal face;
a memory card connector within the receiving recess and attached to the internal face; and
at least one electrically conductive track, each of which forms a conductive path that extends over the internal face, through the internal and external faces through at least one via, and over the external face,
wherein:
when a smartcard having a chip is inserted into the receiving recess, an electrical connection is made between the chip and the memory card connector, and signals may be communicated from the chip through the electrical connection and the at least one electrically conductive track; and
the at least one conductive track forms a dual-faced protective mesh for the memory card connector.

2. The memory card reader body according to claim 1 , wherein one of the at least one electrically conductive track is an active-signal-conducting type track, each extremity of which is terminated by a connection pin situated on the internal face, said active-signal-conducting type track extending from the internal face to the external face through a first electrically conductive via and from the external face to the internal face through a second electrically conductive via.

3. The memory card reader body according to claim 1 , wherein one of the at least one electrically conductive track is a ground type track, each extremity of which is terminated by a connection pin situated on the internal face, said ground type track extending from the internal face to the external face through a third electrically conductive via and from the external face to the internal face through a fourth electrically conductive via.

4. The memory card reader body according to claim 1 , wherein the external face is covered with a thermosetting resin.

5. The memory card reader body according to claim 1 , wherein the external face is covered with a thermoplastic resin.

6. The memory card reader body according to claim 1 , comprising a protective cover mounted on the external face.

7. The memory card reader body according to claim 6 , wherein said protective cover is sealed to the external face by a thermosetting glue or cyanoacrylate glue.

8. The memory card reader body according to claim 1 , wherein said internal face and/or said external face has at least one area in relief on which at least one of the at least one electrically conductive track extends.

9. The memory card reader body according to claim 1 , wherein each of said at least one electrically conductive track takes the form of a loop having a determined geometrical shape.

10. A memory card reader comprising the memory card reader body according to claim 1 .

11. A terminal comprising the memory card reader according to claim 10 .

12. A method for manufacturing a dual-faced protective mesh of a memory card connector for a memory card reader body having an internal face and an external face, wherein the internal face and the external face form opposing sides of the memory card reader body, the method comprising:
defining a geometrical shape of at least one electrically conductive track;
defining a location of said at least one through via;
forming said at least one conductive track having the geometrical shape and forming a conductive path that extends over the internal face, through the internal and external faces through at least one via, and over the external face to form the protective mesh; and
connecting the at least one electrically conductive track to the memory card connector, which is received within a receiving recess of the internal face and attached to the internal face,
wherein when a smartcard having a chip is inserted into a receiving recess formed on the internal face, an electrical connection is made between the chip and the memory card connector, and signals may be communicated from the chip through the electrical connection and the at least one electrically conductive track.

13. The memory card reader body of claim 1 , wherein each of the at least one electrically conductive track includes a pair of ends, each of which terminates at a contact pin.

14. The memory card reader body of claim 13 , wherein the memory card connector is connected to at least one of the contact pins.

15. A memory card reader comprising:
a memory card reader body comprising:
an internal face and an external face, wherein the internal face and the external face form opposing sides of the memory card reader body;
a receiving recess formed on the internal face;
a memory card connector within the receiving recess and attached to the internal face; and
at least one electrically conductive track, each of which forms a conductive path that extends over the internal face, through the internal and external faces through at least one via, and over the external face; and

card reader electronics connected to the memory card connector,
wherein:
when a smartcard having a chip is inserted into the receiving recess, an electrical connection is made between the chip and the memory card connector, and signals may be communicated from the chip through the electrical connection and the at least one electrically conductive track to the card reader electronics; and
the at least one conductive track forms a dual-faced protective mesh for the memory card connector.
