SIM card slot having a fool-proof function and electronic apparatus containing the SIM card slot
View Patent ↗The embodiments of the present invention provide a SIM card slot having a fool-proof function and electronic apparatus containing the SIM card slot. The SIM card slot comprises: an accommodating space for accommodating the SIM card; and a cover, which may be of metal, positioned above the accommodating space; wherein a recessed zone is arranged in the cover, the recessed zone constituting a stopping sheet for blocking the insertion of the bevel edge of the SIM card. The wrong insertion of the SIM card of the electronic apparatus, such as a mobile terminal, may be prevented by the SIM card slot having a fool-proof function and electronic apparatus containing the SIM card slot of the present invention. Upon correct insertion the SIM card edge will cause the stopping sheet to be lifted, but with incorrect insertion the stopping sheet will engage the card bevel edge to block further insertion.
1. A subscriber identity module (SIM) card slot, comprising:
an accommodating space for accommodating a SIM card that has a bevel edge, the bottom of the accommodating space being provided with an opening from which a SIM card identifying terminal arranged on a circuit board of electronic apparatus may be exposed; and
a cover above the accommodating space;
wherein a recessed zone is arranged in the cover, the recessed zone comprising a stopping sheet for blocking the insertion of the bevel edge of the SIM card.
2. The SIM card slot according to claim 1 , wherein the cover is metal and the recessed zone is formed by a punch process.
3. The SIM card slot according to claim 1 , wherein the accommodating space comprises an independent SIM card support structure, or comprising a recessed structure on the body of the electronic apparatus.
4. The SIM card slot according to claim 1 , wherein the cover is metal, the stopping sheet has a fixed end attached to the metal cover, and the fixed end of the stopping sheet is spaced apart at a certain distance from an edge of the metal cover which is in parallel with the insertion path of a SIM card into the SIM card slot.
5. The SIM card slot according to claim 1 , wherein the stopping sheet has a free end that is not attached to the cover, and the distance between the free end of the stopping sheet and an edge of the cover which is in parallel with the insertion path of a SIM card into the SIM card slot is less than or equal to the projection distance of a fool-proof angle of the SIM card in the direction perpendicular to the insertion path.
6. The SIM card slot according to claim 1 , wherein the stopping sheet has a fixed end attached to the cover and a free end that is not attached to the cover, the stopping sheet is in a shape of trapezoid, the lower bottom of the trapezoid being the fixed end of the stopping sheet, and the upper bottom of the trapezoid being the free end of the stopping sheet.
7. The SIM card slot according to claim 1 , wherein the stopping sheet is one piece or two pieces in symmetry.
8. Electronic apparatus, comprising a SIM card identifying terminal arranged on a circuit board of the electronic apparatus and a SIM card slot arranged above the SIM card identifying terminal, the SIM card slot being used for the insertion of the SIM card, and the SIM card being in contact with the identifying terminal after being inserted into the SIM card slot, wherein the SIM card slot comprises:
an accommodating space for accommodating the SIM card, the bottom of the accommodating space having an opening from which the SIM card identifying terminal arranged on the circuit board of the electronic apparatus is exposed; and
a cover positioned above the accommodating space;
wherein a recessed zone is arranged in the cover, the recessed zone comprising a stopping sheet for blocking the insertion of the bevel edge of the SIM card.
9. The electronic apparatus according to claim 8 , wherein the cover is metal and the recessed zone is formed by a punch process.
10. The electronic apparatus according to claim 8 , wherein the accommodating space comprises an independent SIM card support structure, or comprises a recessed structure on the body of the electronic apparatus.
11. The electronic apparatus according to claim 8 , wherein the stopping sheet has a fixed end attached to the cover, and the fixed end of the stopping sheet is spaced apart at a certain distance from an edge of the cover which is in parallel with the insertion path of a SIM card into the SIM card slot.
12. The electronic apparatus according to claim 8 , wherein the stopping sheet has a free end that is not attached to the cover, and the distance between the free end of the stopping sheet and an edge of the cover which is in parallel with the insertion path of a SIM card into the SIM card slot is less than or equal to the projection distance of a fool-proof angle of the SIM card in the direction perpendicular to the insertion path.
13. The electronic apparatus according to claim 8 , wherein the stopping sheet has a fixed end attached to the cover and a free end that is not attached to the cover, the stopping shape is in a shape of trapezoid, the lower bottom of the trapezoid being the fixed end of the stopping sheet, and the upper bottom of the trapezoid being the free end of the stopping sheet.
14. The electronic apparatus according to claim 8 , wherein the stopping sheet is one piece or two pieces in symmetry.
15. The SIM card slot according to claim 1 , wherein the cover is a metal cover.
16. The electronic apparatus according to claim 8 , wherein the cover is a metal cover.
