Problems solved by technology

The procedure to connect the top cover shell to the bottom cover shell is complicated.
Further, when molding the plastic covering on the top and bottom cover shell, the high temperature of the molding plastics may cause the USB connector of the circuit board to deform.
Because the memory stick has no means to support the USB connector firmly inside the cover shells, the USB connector may be damaged easily during installation.

first embodiment

[0026] Referring to FIGS. 1˜6, a memory stick in accordance with the present invention is shown comprised of a metal casing 1, a hollow plastic shell 2, a circuit board 3, a locating frame 4, and an end cap 5.

[0027] The metal casing 1, as shown in FIG. 1, is adapted to accommodate the circuit board 3, having two shoulders 11 symmetrically disposed at two opposite lateral sides thereof, a front extension 12 forwardly extended from the front end between the shoulders 11 for insertion into a USB socket of a computer, and two eyelet lugs 13 backwardly extended from the rear end and arranged in parallel.

[0028] The hollow plastic shell 2 is molded from plastics and capped onto the metal casing 1, keeping the front extension 12 and the eyelet lugs 13 exposed to the outside (see FIG. 2).

[0029] The circuit board 3, as shown in FIG. 3, is an electronic circuit assembly constructed according to known techniques to provide a specific function or a combination of functions, having a USB connec...

second embodiment

[0033] FIGS. 7˜11 show a memory stick having a USB port according to the present invention. According to this embodiment, the eyelet lugs 13a of the metal casing, referenced by 1a, are stamped to have a plurality of inwardly projected hook portions 131a; a hollow first end cap element 51a is capped on the eyelet lugs 13a of the metal casing 1a and inserted into one end of the plastic shell 2; a solid second end cap element 52a is inserted into the first end cap element 51a and the inside of the metal casing 1a between the eyelet lugs 13a. The second end cap element 52a has a plurality of retaining holes 521a respectively forced into engagement with the inwardly projected hooked portions 131a of the eyelet lugs 13a of the metal casing, referenced by 1a.

[0034]FIG. 12˜16 show a memory stick having a USB port according to a third embodiment of the present invention. According to this embodiment, the memory stick is comprised of a metal casing 1b, a hollow plastic shell 2a, a circuit bo...

Abstract

A memory stick includes a plastic shell, an elongated metal casing mounted in the plastic shell and having a front extension exposed to the outside of the plastic shell for insertion into a USB socket of a computer, a circuit board mounted inside the elongated metal casing and having a USB connector suspended in the front extension of the elongated metal casing, a locating frame mounted inside the metal casing to support the circuit board, and an end cap capped on the rear end of the circuit board and inserted with the circuit board into the rear end of the hollow plastic shell.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The present invention relates a memory stick and more particularly, to a memory stick having a USB port that is comprised of a metal casing, a plastic shell, a circuit board, a locating frame, and an end cap. [0003] (b) Description of the Prior Art [0004] A conventional memory stick having a USB (Universal Serial Bus) port essentially comprises a bottom cover shell, a top cover shell covering the bottom cover shell, a circuit board mounted in between the bottom cover shell and the top cover shell, and a plastic covering molded on the top and bottom cover shells. The procedure to connect the top cover shell to the bottom cover shell is complicated. Further, when molding the plastic covering on the top and bottom cover shell, the high temperature of the molding plastics may cause the USB connector of the circuit board to deform. Because the memory stick has no means to support the USB connector firmly inside the cove...
