Description
The present invention relates to a personal computer peripheral device, and more particularly to a flash memory device with a telescopic connector port and a casing of the flash memory device for protecting the connector port.
With the fast development of the electrical domain, flash memory is currently used in variety of apparatus including digital cellular phones, digital cameras, PC cards, and digital setup boxes or inner controllers for notebook computers. A flash memory device such as a U-disk is widely used as an intermedium for accessing data files from one device to another, or like a portable hard drive for installing data.
Usually, a flash memory device includes a circuit board with a plurality of electronic components, such as driver chip, memory chip, oscillator, resistor, etc. for saving and loading data, functioning as a miniature hard drive or wireless communication/transmission, a connector port connected to one end of the circuit board, and a cover enclosing the circuit board. The connector port extends out of the cover for connecting with various peripherals. The connector port is usually housed and protected from dust by a detachable cap.
However, when such flash memory device is connected with a host device, such as a computer, its detached cap may be left unnoticed near the computer and lost due to its small size. Once the extra cap is lost, the connector port cannot be easily shielded from dust and might be damaged by outside forces.
Hence, an improved flash memory device and a casing thereof are needed to solve the problem above.
The present invention provides a flash memory device including a cover, an electrical module received in the cover, a slider and a rotatable member for driving the slider so that the electrical module can be moveable respect to the cover. The cover defines a receiving chamber extending along a longitudinal direction and an opening communicating with the receiving chamber. The electrical module is slideably received in the receiving chamber and includes a circuit board and a connector port electrically connected with the circuit board. The slider is slideably mounted in the receiving chamber and defines a slot extending along a transverse direction perpendicular to the longitudinal direction. The rotatable member has a fixed axis around which the rotatable member revolves. The rotatable member includes a protrusion slideably received in the slot. The connector port is driven to telescopically extend through the opening by the slider which is further driven by the protrusion.

FIG. 2 is an exploded view of the flash memory device shown in FIG. 1;
FIG. 3 is a part perspective view of the flash memory device with a top part removed therefrom in order to illustrate a status when the connector port extends beyond the cover;
FIG. 4A is a top view of the flash memory device with a bottom part and a spin button both removed therefrom under a condition that the connector port extends beyond the cover; and
FIG. 4B is another top view of the flash memory device similar to FIG. 4A while showing the connector port gets back inside the cover.
Referring to FIGS. 1 and 2, a flash memory device 100 which can be used for data transmission with a host device according to a preferred embodiment of the present invention is disclosed. The flash memory device 100 includes a cover 1, an electrical module 2, a frame 3 for mounting the electrical module 2, a slider 4, a rotatable member 5 for driving the slider 4 and a spin button 6 assembled to the cover 1.
The cover 1 is substantial rectangular shaped and defines a receiving chamber 11 extending along a longitudinal direction A-A and an opening 12 formed at a front end 13 of the cover 1 and communicating with the receiving chamber 11. The cover 1 includes a top part 14 and a bottom part 15 attached to the top part 14 with the receiving chamber 11 sandwiched between the top and the bottom parts 14, 15. The top part 14 includes a pair of first and second ribs 141, 142 formed on an inner side 140 thereof, and a through hole 143 defined through the top part 14. The first and the second ribs 141, 142 are aligned with each other for positioning the rotatable member 5, which will be detailed hereinafter. The through hole 143 is located between the pair of first and the second ribs 141, 142 and communicates with the receiving chamber 11.
The electrical module 2 includes a circuit board 21 and a connector port 22 mechanically and electrically connected with the circuit board 21. The circuit board 21 includes a pair of recesses 210 formed on lateral sides thereof. A plurality of chips 211 are mounted on the circuit board 21 for processing signals. According to the preferred embodiment of the present invention, the connector port 22 is a standard USB plug but not limited. That is to say the connector port 22 can be PCI interface, SATA interface etc.
The frame 3 is rectangular shaped and includes a pair of side walls 31, 32, a front side 33 and a rear side 34 opposite to the front side 33. A cavity 35 is formed between the pair of side walls 31, 32 for accommodating the circuit board 21. Each side wall 31, 32 includes a projection 311 extending into the cavity 35 to be received in the recesses 210 so that the circuit board 21 can be firmly fixed in the frame 3. As a result, the electrical module 2 can be slideable in the receiving chamber 11. As shown in FIGS. 3 and 4A, after the circuit board 21 is assembled to the frame 3, the connector port 22 extends beyond the frame 3 through the front side 33.
Referring to FIGS. 2-4A, the slider 4 include a base 41, a pair of fastening portions 42 perpendicular to the base 41 and a pair of connecting portions 43 connecting the fastening portions 42 and the base 41. The base 41 is rectangular shaped and includes a rectangular slot 410 extending along a transverse direction perpendicular to the longitudinal direction A-A as shown in FIG. 3. The slot 410 is enclosed by four peripheral walls 411. The fastening portions 42 are fixed in a slit 340 defined in the rear side 34 of the frame 3 so that the slider 4 and the frame 3 can be moveable together in the receiving chamber 11. According to the preferred embodiment of the present invention, the electrical module 2 is directly driven by the frame 3 which is further directly driven by the slider 4. That is to say, the electrical module 2 is indirectly driven by the slider 4. However, in other embodiments, the frame can be omitted and under this condition the slider 4 can be directly fixed to the circuit board 21.
The rotatable member 5 is received in the receiving chamber 11 as well and defines a fixed axis 51, an offset portion 52 offset from the fixed axis 51 and a protrusion 53 fixed to the offset portion 52. The rotatable member 5 is a crank so that the protrusion 53 can 360-degree revolve around the fixed axis 51. The offset portion 52 includes a post 521 and the protrusion 53 defines a hole 531 to receive the post 521 so that the protrusion 53 can be fixed to the offset portion 52 and can be rotatable together with the offset portion 52. According to the preferred embodiment of the present invention, the protrusion 53 and the offset portion 52 are two independent elements and can be fixed together. However, it is obvious to those of ordinary skill in the art that the protrusion 53 can be integrally molded with the offset portion 52. When the rotatable member 5 revolves around the fixed axis 51, the protrusion 53 is slideable in the slot 410 of the slider 4 through its out surfaces abutting against the peripheral walls 411. Because the fixed axis 51 can't move along the longitudinal direction A-A, the slider 4 is then driven to move along the longitudinal direction A-A. Since the slider 4, the frame 3 and the electrical module 2 are fixed together, the connector port 22 can be slideable along the longitudinal direction A-A to alternatively extend beyond the opening 12 as best shown in FIGS. 3 and 4A.
The spin button 6 is assembled to the top part 14 and includes a handle portion 61 extending beyond the top part 14 and a contracted post 62 extending from the handle portion 61. The post 62 is fixed to the rotatable member 5 through the through hole 143 so that they can be rotatable together. The fixed axis 51 extends through the spin button 6 along a direction perpendicular to the longitudinal direction A-A and the transverse direction. The handle portion 61 is driven by the end user to be rotatable in a horizontal plane and along the direction B-B. As shown in FIG. 4A, the first rib 141 stops the rotatable member 5 at a first position where the connector port 22 extends beyond the opening 12. The second rib 142 stops the rotatable member 5 at a second position where the connector port is hidden in the opening as shown in FIG. 4B.
