Description
TECHNICAL FIELD

The present application relates to the field of connector, particularly to a new connector applied to USF cards and Micro SD cards.


BACKGROUND

USF is a storage standard drafted by many semiconductor corporations of the industry to replace eMMC and SD cards, every channel of the transmission interface of which has a transmission rate ranging from 2.9 to 5.8 Gbps. Even UFS 1.0 provides a bandwidth of 600 MB/s for every channel in each direction, needless to say UFS 2.0 doubles that to 1.2 GB/s.


The contour of a UFS card is irregular with one wave shaped side and has a length of 15 mm at most, a width of 11 mm at most and a thickness of 1.0 mm at most.


Nowadays more and more cell phones are provided with UFS high speed flash memory cards. Compared with currently popular Micro SD cards, UFS cards are faster to transmit. Therefore, the use of Micro SD cards has been eliminated from a new generation of cell phone products of many dominant brands.


However. Micro SD cards are still widely used, as a result of which people has been seeking a coexistence way of UFS cards and Micro SD cards.

To solve above described technical problems, the present application provides a new connector of high speed and density applied to USF cards and Micro SD cards.


To achieve above described objective, the technical solutions to the application are detailed as follows:

    • a new connector applied to USF cards and Micro SD cards comprises an end component, a frame and an outer shell, wherein the end component is provided in the frame covered with the outer shell;
    • a UFS card or Micro SD card can be inserted into the frame and connected with the end component;
    • the end component includes nineteen ends, i.e., Pin 1 to Pin 19.
      • The ends of the inserted UFS card or Micro SD card can be connected with respective ends of the end component, details are shown in FIGS. 4 and 5.
    • FIG. 4 gives end correspondence between the UFS card and the present connector.

      • The end ‘Pin 19’ is used as a switch and is “normally open” when there isn't any card inserted within it; the Pin 19 is converted to “closed” and is connected with the end u11 of the UFS card when a UFS card is inserted into the present connector; and the ‘Pin 19’ will be returned to its “normally open” state when the UFS card is pulled out of the connector.
      • FIG. 5 gives end correspondence between the Micro SD card and the present connector.
    • The Micro SD card includes eight ends, i.e., m1 to m8.
      • The end ‘Pin 19’ is used as a switch and is “normally open” when there isn't any card inserted within it; the ‘Pin 19’ is converted to “closed” and is connected with the end m6 of the Micro SD card when a Micro SD card is inserted into the present connector; and the ‘Pin 19’ will be returned to its “normally open” state when the Micro SD card is pulled out of the connector.
