4. The card connector according to claim 3 , wherein the locking units comprise locking ribs.
5. The card connector according to claim 2 , wherein elastic assemblies are disposed between the locking units and the bottom board.
6. The card connector according to claim 5 , wherein the elastic assemblies comprise springs.
7. The card connector according to claim 4 , wherein the locking ribs are provided with a slope along the card insertion direction, so that the slope helps the first card press down the locking ribs.
8. The card connector according to claim 7 , wherein the locking ribs are in a one-section structure or the locking ribs are in a multi-section structure.
9. The card connector according to claim 1 , wherein the bottom board further comprises:
pins; and
electrical contacts disposed in middle positions of the first card and the second card, and wherein the first card and the second card come into contact with the pins by means of the electrical contacts to implement an electrical connection with the card connector.
10. A terminal, comprising:
a device; and
a card connector disposed on the device, the card connector being suitable for insertion of a card along a card insertion direction, wherein the card comprises a first card and a second card, a size of the first card is greater than a size of the second card, the card connector comprising:
a bottom board, comprising,
one lateral side of the bottom board providing an opening for card insertion along a card insertion direction,
side walls located on lateral sides of the bottom board other than the lateral side on which the opening for card insertion is located forming a first-size area for holding the first card,
locking units forming a second-size area for holding the second card, wherein the second-size area is located within the first-size area and the locking units are capable of being pressed down or sprung back, and
wherein the card connector is configured so that:
the first card and the second card are insertable along the card insertion direction through the opening for card insertion;
when the first card is inserted along the card insertion direction into the card connector through the opening for card insertion, the locking units are pressed down by the first card, and the first card is locked within the first-size area formed by the side walls; and
when the second card is inserted along the card insertion direction into the card connector through the opening for card insertion, the locking units automatically spring back, and the second card is locked within the second-size area formed by the locking units.
11. A base suitable for insertion of a device along a device insertion direction, wherein the device comprises a first device and a second device, a size of the first device is greater than a size of the second device, the base comprising:
a bottom board comprising,
one lateral side of the bottom board providing an opening for device insertion along a device insertion direction,
side walls located on lateral sides of the bottom board other than the lateral side on which the opening for device insertion is located forming a first-size area for holding the first device, and
locking units forming a second-size area for holding the second device, wherein the second-size area is located within the first-size area and the locking units are capable of being pressed down or sprung back; and
wherein the base is configured so that:
the first device and the second device are insertable along the device insertion direction through the opening for device insertion,
when the first device is inserted along the device insertion direction into the base through the opening for device insertion, the locking units are pressed down by the first device, and the first device is locked within the first-size area formed by the side walls, and
when the second device is inserted along the device insertion direction into the base through the opening for device insertion, the locking units automatically spring back, and the second device is locked within the second-size area formed by the locking units.
