Abstract

A support part for an LCD display module of an electronic device includes at least one element for receiving a press device for pressing a dummy key. The support part at least one attachment element for securing the part to a printed circuit board of the electronic device such that the press device is compressed between the support part and the printed circuit board.

First claim

The invention claimed is:

1. A support part for supporting an LCD display module of an electronic device, which has a printed circuit board with a dummy key having a state activatable by an applied force, the support part comprising:
at least one receiving element configured to receive a pressing device distinct from the support part and which is compressible to apply a pressing force on the dummy key; and
at least one attaching element providing an attachment in a space between the support part and the PCB to secure said support part to the PCB of the electronic device such that the pressing device is compressed between said support part and said dummy key on the PCB.

2. The support part according to claim 1 , wherein said receiving element is a cylinder capable of receiving a portion of said pressing device.

3. The support part according to claim 1 , wherein said attaching element takes the form of a toe.

4. A system for securing an electronic device comprising:
a support part for supporting an LCD display device; and
a PCB comprising at least one dummy key having a state activatable by an applied force,
said support part comprising at least one receiving element configured to receive a pressing device distinct from the support part and which is compressible to apply a pressing force on said dummy key, and said support part comprising an attaching element providing an attachment in a space between the support part and the PCB to secure said support part to the PCB such that the pressing device is compressed between said support part and said dummy key of the PCB.

5. The system for securing according to claim 4 , wherein said receiving element is a cylinder, a portion of the pressing device being inserted into said cylinder.

6. The system for securing according to claim 4 , wherein said attaching element takes the form of a toe.

7. The system for securing according to claim 6 , further comprising a holding element soldered to said PCB board, said toe being inserted into a notch disposed in said holding element.

8. The system for securing according to claim 7 , wherein said holding element forms part of an electromagnetic shielding element fixedly attached to said PCB.

9. An electronic device comprising:
a support part for supporting an LCD display device; and
a PCB comprising at least one dummy key having a state activatable by an applied force,
said support part comprising at least one receiving element configured to receive a pressing device distinct from the support part and which is compressible to apply a pressing force on said dummy key, and said support part comprising an attaching element providing an attachment in a space between the support part and the PCB to secure said support part to the PCB such that the pressing device is compressed between said support part and said dummy key of the PCB.

10. The electronic device according to claim 9 , further comprising the LCD display device, wherein the attaching element attached to the PCB board generates a force FM that holds said support part attached to said PCB board, said pressing device exerting a force FD on the dummy key of the PCB board and a force FD′ on the support part, said LCD display device exerting a force FC on said support part, the force FD being sufficient to activate the dummy key.

11. The electronic device according to claim 9 , wherein the value of the force FM is equal to the value of the force FD′.

12. The electronic device according to claim 9 , wherein the value of the force FD′ is equal to the value of the sum of the force FM and the force FC, the value of the force FC being greater than zero.

13. The electronic device according to claim 9 , further comprising a casing and the LCD display device, said LCD display device being disposed between an upper part of said casing and the support part.

14. The electronic device according to claim 9 , wherein said electronic device is a payment terminal.
