Abstract

A card socket for use in an electronic device is disclosed, wherein two cards may be inserted on top of one another into the card insertion space, so that both of the two cards may be used continuously. The card socket according to one embodiment of this disclosure for use in an electronic device comprises a housing having a space wherein a card is inserted, wherein the housing comprises a step part having a staircase shape in the card insertion direction within the card insertion space, so that two or more cards may be inserted on top of one another.

First claim

The invention claimed is:

1. A card socket for use in an electronic device, the card socket being configured to have first and second cards received therein at the same time with the second card being positioned on top of the first card, the card socket comprising:
a housing having a card insertion space which is open at a front end of the housing, wherein the card insertion space is configured to have the first and second cards inserted therein from the front end, the housing having a step part having a staircase shape which extends upwardly into the card insertion space in order to separate the card insertion space into a first card insertion part and a second card insertion part, the first card insertion part being positioned forward of the step part, the second card insertion part being positioned above the first card insertion part and above the step part; and
a contact terminal assembly installed in the housing, the contact terminal assembly having first contact terminals and second contact terminals which are in direct contact with one another, the first contact terminals being positioned forward of the step part and extending upwardly into the first card insertion part, the second contact terminals being positioned rearward of the step part and extending upwardly into the second card insertion part,
wherein, in operation, the first card insertion part is configured to receive the first card therein and the first contact terminals are configured to contact a bottom of the first card, and the second card insertion part is configured to receive the second card therein, while the first card is received in the first card insertion part, and the second contact terminals are configured to contact a bottom of the second card.

2. The card socket according to claim 1 , wherein a front end of the step part is configured to block further entry of the first card into the first card insertion part.

3. The card socket according to claim 1 , wherein the step part has an upwardly and rearwardly sloping surface which is configured to contact and guide the second card as it is inserted into the second card insertion part.

4. The card socket according to claim 1 , wherein the second contact terminals are generally C-shaped in configuration.

5. The card socket according to claim 4 , wherein the second contact terminals have a support part, a bending part, and a contact part, the support part extending rearwardly from the step part to the bending part, the bending part extending forwardly and upwardly to the contact part, the contact part being at least partially positioned within the second card insertion part in order to allow the bottom of the second card to contact the contact part.

6. The card socket according to claim 5 , wherein the contact part has a top bent part and a front end part, the top bent part being positioned within the second card insertion part in order to allow the bottom of the second card to contact the top bent part of the contact part, the front end part extending forwardly and downwardly from the top bent part.

7. The card socket according to claim 1 , wherein the second contact terminals have a soldering part at a forward end thereof, the first contact terminals being connected to the soldering part.

8. The card socket according to claim 1 , wherein the first and second contact terminals are integrally formed.

9. A card socket for use in an electronic device, the card socket being configured to have first and second cards received therein at the same time with the second card being positioned on top of the first card, the card socket comprising:
a housing having front and rear ends and side ends, the housing having a card insertion space which is open at the front end of the housing, wherein the card insertion space is configured to have the first and second cards inserted therein from the front end of the housing, the card insertion space further being configured to prevent the first and second cards from being inserted therein from the rear and side ends of the housing, the housing having a step part having a staircase shape which extends upwardly into the card insertion space in order to separate the card insertion space into a first card insertion part and a second card insertion part, the first card insertion part being positioned between the front end of the housing and the step part, the second card insertion part being positioned above the first card insertion part and above the step part; and
a contact terminal assembly installed in the housing, the contact terminal assembly having first contact terminals and second contact terminals which are in direct contact with one another, the first contact terminals being positioned forward of the step part and extending upwardly into the first card insertion part, the second contact terminals being positioned rearward of the step part and extending upwardly into the second card insertion part,
wherein, in operation, the first card insertion part is configured to receive the first card therein via the front end of the housing and the first contact terminals are configured to contact a bottom of the first card, and the second card insertion part is configured to receive the second card therein via the front end of the housing, while the first card is received in the first card insertion part, and the second contact terminals are configured to contact a bottom of the second card.

10. The card socket according to claim 9 , wherein a front end of the step part is configured to block further entry of the first card into the first card insertion part.

11. The card socket according to claim 9 , wherein the step part has an upwardly and rearwardly sloping surface which is configured to contact and guide the second card as the second card is inserted into the second card insertion part.

12. The card socket according to claim 9 , wherein the second contact terminals are generally C-shaped in configuration.

13. The card socket according to claim 12 , wherein the second contact terminals have a support part, a bending part, and a contact part, the support part extending rearwardly from the step part to the bending part, the bending part extending forwardly and upwardly to the contact part, the contact part being at least partially positioned within the second card insertion part in order to allow the bottom of the second card to contact the contact part.

14. The card socket according to claim 13 , wherein the contact part has a top bent part and a front end part, the top bent part being positioned within the second card insertion part in order to allow the bottom of the second card to contact the top bent part of the contact part, the front end part extending forwardly and downwardly from the top bent part.

15. The card socket according to claim 9 , wherein the second contact terminals have a soldering part at a forward end thereof, the first contact terminals being connected to the soldering part.

16. The card socket according to claim 9 , wherein the first and second contact terminals are integrally formed.
