A battery cover grounding device for a portable terminal including a metallic battery cover is provided. The grounding device includes a grounding member installed on the terminal to be connected to a grounding surface of the terminal and to be in contact with the battery cover. The grounding member has a cover protrusion formed on the battery cover and a grounding protrusion attached to the terminal to contact the cover protrusion. In this manner, the metallic battery cover is connected to the grounding surface of the terminal to minimize the possibility of current leakage, to improve the stability of the operation of the terminal, and to minimize potential malfunctions of the terminal due to static electricity.

What is claimed is: 1. A battery cover grounding device for a portable terminal, comprising: a metallic battery cover; and a grounding member disposed on the terminal to be connected to a grounding surface of the terminal and to be in contact with the battery cover, the grounding member comprising a cover protrusion on the battery cover and a grounding protrusion on the terminal to contact the cover protrusion. 2. The device as claimed in claim 1, wherein an insulation material is applied to at least a portion of the battery cover. 3. The device as claimed in claim 2, wherein a portion of the insulation material on the cover protrusion is removed. 4. The device as claimed in claim 1, wherein the grounding surface of the terminal comprises electromagnetic interference (EMI) paint disposed on an inner surface of the housing of the terminal. 5. The device as claimed in claim 1, further comprising a fastener hole formed on the terminal and a fastener extending through the fastener hole, and wherein the grounding protrusion comprises a cap coupled to the fastener and the grounding protrusion is connected to the grounding surface of the terminal by the fastener. 6. The device as claimed in claim 5, wherein the grounding surface of the terminal is a ground pattern configured on a printed circuit board of the terminal, and the fastener is fastened to a fastening hole formed on the ground pattern. 7. The device as claimed in claim 1, wherein the grounding protrusion comprises a flexible conductive tape. 8. A portable terminal, comprising: a housing having a battery opening; a metallic battery cover for closing the battery opening; and a grounding member for grounding the metallic battery cover to a grounding surface of the portable terminal, wherein when the battery pack has been installed into the battery opening, the metallic battery cover is attached to the housing to close the battery opening and protect the battery pack. 9. The portable terminal as claimed in claim 8, wherein the grounding member comprises a cover protrusion on the battery cover and a grounding protrusion on the terminal, the grounding protrusion contacting the cover protrusion when the cover is closed. 10. The portable terminal as claimed in claim 9, further comprising a fastener hole formed on the terminal and a fastener extending through the fastener hole, the fastener connecting the grounding protrusion to the grounding surface of the terminal. 11. The portable terminal as claimed in claim 10, wherein the grounding protrusion comprises a cap coupled to the fastener. 12. The portable terminal as claimed in claim 10, wherein the grounding surface comprises a ground pattern on a printed circuit board disposed in the housing, and the fastening hole is formed on the ground pattern of the printed circuit board. 13. The portable terminal as claimed in claim 9, wherein the grounding protrusion comprises a flexible conductive tape. 14. The portable terminal as claimed in claim 8, wherein the grounding surface of the portable terminal comprises electromagnetic interference (EMI) paint disposed on an inner surface of the housing of the terminal. 15. The portable terminal as claimed in claim 8, wherein the grounding surface comprises a ground pattern on a printed circuit board disposed in the housing. 16. The portable terminal as claimed in claim 8, wherein the battery cover comprises a stainless steel material. 17. A portable terminal, comprising: a housing having an opening for receiving a battery pack, the housing having a grounding surface and a grounding protrusion; and a metallic battery cover for closing the opening in the housing, the cover having a cover protrusion, wherein the grounding protrusion of the housing contacts the cover protrusion to form an electrically conductive path between the grounding surface and the metallic cover when the cover is closed. 18. The portable terminal as claimed in claim 17, wherein the grounding protrusion comprises a cap coupled to a fastener extending through a fastener hole on the housing. 19. The portable terminal as claimed in claim 17, wherein the housing comprises a recess for receiving the battery cover. 20. The portable terminal as claimed in claim 19, wherein at least part of the grounding surface is formed on the recess for receiving the battery cover.
