Abstract

A memory card adapter includes a body having a set of contact pins. The set of contact pins include input pins and output pins implemented in a pin-to-pin structure. The input pins connect with pins of an inserted memory card and the output pins connect with an external socket. The body includes a bottom lead adapted to support the main body, and a top lead adapted to be combined with the bottom lead. The body includes a fixing substance adapted to combine with the contact pins. The body includes a conduction plate on a top surface or a bottom surface of the fixing substance, where the conduction plate is connected to at least one of the contact pins.

First claim

a fixing substance configured to combine with the set of contact pins; and
a conduction plate on one of a top surface and a bottom surface of the fixing substance, the conduction plate being connected to at least one contact pin of the set of contact pins to form a return path and being disposed on the entire top surface area or the entire bottom surface area of the fixing substance,
wherein the set of contact pins includes at least one ground pin.

2. The memory card adapter of claim 1 , further comprising:
a bottom lead configured to support the body; and
a top lead configured to be combined with the bottom lead.

3. The memory card adapter of claim 1 , wherein a number of the input pins is equal to a number of the output pins.

4. The memory card adapter of claim 1 , wherein
at least two of the output pins are supplied with a ground voltage, and
the at least two output pins are electrically connected.

5. The memory card adapter of claim 1 , wherein the conduction plate is connected to the ground pin.

6. The memory card adapter of claim 5 , wherein the conduction plate includes a set of protrusions, and the fixing substance comprises:
a first groove configured to receive a first protrusion of the set of protrusions, the fixing substance being engaged with the conduction plate when the conduction plate is connected to one of the output pins that corresponds to the ground pin; and
a second groove configured to receive a second protrusion of the set of protrusions, the fixing substance being engaged with the conduction plate when the conduction plate is connected to one of the input pins that corresponds to the ground pin.

7. The memory card adapter of claim 1 , wherein the conduction plate is connected to a first pin and a second pin from among the contact pins, the first pin and the second pin being supplied with a ground voltage.

8. The memory card adapter of claim 7 , wherein the conduction plate includes a set of protrusions, and the fixing substance comprises:
a first groove configured to receive a first protrusion of the set of protrusions, the fixing substance being engaged with the conduction plate when the conduction plate is connected to one of the output pins that corresponds to the second pin;
a second groove configured to receive a second protrusion of the set of protrusions, the fixing substance being engaged with the conduction plate when the conduction plate is connected to one of the input pins that corresponds to the second pin; and
a third groove configured to receive a third protrusion of the set of protrusions, the fixing substance being engaged with the conduction plate when the conduction plate is connected to one of the output pins that corresponds to the first pin.

9. The memory card adapter of claim 1 , wherein, when the conduction plate is on the top surface of the fixing substance, the conduction plate comprises:
a first protrusion on the top surface of the fixing substance, the first protrusion being connected to the at least one contact pin such that when the first protrusion is connected to the at least one contact pin, the conduction plate forms the return path, and the first protrusion has a square plate shape.

10. The memory card adapter of claim 9 , wherein the conduction plate further comprises:
a second protrusion on the top surface of the fixing substance, the second protrusion including a slice structure, the slice structure being a strip of material projecting from the conduction plate that allows the conduction plate to connect with the fixing substance.

11. The memory card adapter of claim 10 , wherein the fixing substance comprises a slice-shaped groove configured to receive the second protrusion such that, when the second protrusion is received by the slice-shaped groove, the conduction plate is connected with the fixing substance.

12. The memory card adapter of claim 1 , wherein in the pin-to-pin structure, the input pins are arranged perpendicular to the output pins.

13. The memory card adapter of claim 1 , wherein in the pin-to-pin structure, the input pins are arranged in-line with the output pins.

14. The memory card adapter of claim 1 , wherein the memory card is a micro secure digital (SD) card.

15. A mobile device comprising:
an application processor;
a communication module configured to perform wireless communications according to instructions of the application processor;
a display and touch module configured to (i) receive input data and (ii) display output data according to the instructions of the application processor;
a buffer RAM configured to temporarily store data generated during an operation of the application processor;
