Patent Application
20180123302
The present application relates to the field of connector, particularly to a new connector applied to USF cards and Micro SD cards.
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:
Compared with the prior art, the beneficial effects of the present application are that: the new connector is applied to UFS cards and Micro SD cards by optimizing the structure and arrangement of the ends. Specifically, on the basis of existing UFS card connectors, the ends 1-10, 11, 12 and 19 form a complete data transmission structure for the UFS card; at the same time, the ends 11-19 form a complete data transmission structure applied to the Micro SD card, so that the connector is applied to UFS cards and Micro SD cards.
The Pin 19 is used as a switch suitable for hot plugging, to eliminate overheat and to protect memory storage of the UFS card or Micro SD card to prevent the stored data from missing.
The present application will be detailed in connection with
As shown in
As shown in
As shown in
The ends of the inserted UFS card or Micro SD card can be connected with respective ends of the end component A, details are shown in tables 1 and 2:
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.
Table 2 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.
Respective functions of the twelve ends(i.e., u1 to u12) of the UFS card are detailed in table 3:
Respective functions of the eight ends(i.e., m1 to m8) of the Micro SD card are detailed in table 4:

In light of general technical knowledge, present technical solutions can be achieved by other embodiments which are not departed from spiritual substance or essential features of the application. Therefore, above described embodiments are simply illustrative in any way and are not intended to limit the application. All the changes within the range of the application or its equivalent are included in the application itself.
