Further, as shown in Figure 3,4, containing cavity 11 comprises totally-enclosed chamber and the semiclosed chamber of adjacent setting, and the accommodating memory module 2 in totally-enclosed chamber, leading section 41, platform 33 and boss 35 are provided with the part of the first draw-in groove 32; The top butt of the upper wall in semiclosed chamber and boss 35, adopt non-full-closed structure to be convenient to the assembly dismounting of memory module 2, supporter 3, electric contact terminal group 4.

In above-mentioned arbitrary embodiment, small-sized USB joint 5 is Micro-USB joint or Mini-USB joint.

Further, Micro-USB joint 5 is Micro-USB male joint or Micro-USB female joint.At this, be only an embodiment, do not limited.

In this embodiment, the Micro-USB joint of take is example, and Micro-USB joint 5 comprises metal end subgroup 51 and is located at the grab 52 of Micro-USB joint 5 left and right sides, and grab is fixed in boss 35, and metal end subgroup 51 is comprised of four metal terminals.

In this embodiment, electric contact terminal group 4, be comprised of four electric contact terminals.

The tail end 44 of four electric contact terminals is electrically connected with Micro-USB joint 5, four electric contact terminal middle parts are bending structure for gathering section 42, namely from leading section 41 processes of four electric contact terminals, gather bending, the structure of four electric contact terminals reduces gradually, lucky four metal terminals corresponding with the metal end subgroup 51 of Micro-USB joint 5 of size of four electric contact terminal structures are electrically connected one by one, based on this, Micro-USB joint 5, by electric contact terminal group 4, is electrically connected with the metal contact piece group 21 on memory module 2.

Micro-USB joint 5 can make other Micro-USB equipment and memory module 2 carry out exchanges data, make USB flash disk can be directly and other Micro-USB equipment be used in conjunction with, without by patchcord, the USB joint of USB flash disk being changed into to corresponding Micro-USB joint again, thereby realize the Micro-USB linkage function.

Further, electric contact terminal group 4 is the connected modes such as welding or riveted joint with metal end subgroup 51 electricity connection ends 53 of Micro-USB joint 5.

Further, the assembling mode of supporter 3, electric contact terminal group 4 and Micro-USB joint 5 adopts plastic rubber shaping (molding) technology:

At first, adopt welding manner to link together the metal end subgroup of electric contact terminal group 4 and Micro-USB joint 5 51.

Secondly, by the plastic rubber shaping technology, supporter 3, electric contact terminal group 4 and Micro-USB joint 5 are combined: electric contact terminal group 4 and Micro-USB joint 5 are placed in mould, and in mould, inject plastic material, and cooling forming is supporter 3, electric contact terminal group 4 and Micro-USB joint 5 are combined with supporter 3.

Wherein, electric contact terminal group 4 and the position of Micro-USB joint 5 in mould make the leading section 41 of electric contact terminal group 4 just be placed on groove 36 positions of four correspondences of the platform 33 of supporter 3, it is gathered section 42 and is covered by supporter 3, and the metal end subgroup 51 of Micro-USB joint 5 and grab 52 also together are covered by supporter 3, and then by the plastic rubber shaping technology, supporter 3, electric contact terminal group 4 and Micro-USB joint 5 are combined into one.

Again, by supporter 3, electric contact terminal group 4 and Micro-USB joint 5 after the plastic rubber shaping technical combinations is integral, memory module 2 is positioned in the cavity volume 31 of supporter 3 lower surfaces, and the face at metal contact piece group 21 places is close to cavity volume 31, make bulge-structure 43 four metal contact pieces corresponding with metal contact piece group 21 that four electric contact terminal leading sections 41 in electric contact terminal group 4 cave in to bottom be electrically connected one by one.

Finally, supporter 3, memory module 2 are put in the lump to the containing cavity 11 of U 1, and the top of boss 35 and containing cavity 11 upper wall butts, memory module 2 and containing cavity 11 lower wall butts, make the assembly of memory module 2, supporter 3, electric contact terminal group 4 firmly be positioned in the containing cavity 11 of U 1, the product assembled as shown in Figure 2.

In like manner, the Micro-USB of the utility model embodiment is also replaceable is the Mini-USB joint, and because Mini-USB joint and Micro-USB joint all are electrically connected by metal end subgroup and electric contact terminal group 4, this is no longer going to repeat them.

Further, in this embodiment, U 1 outside also is provided with housing, be used to preventing that USB flash disk is damaged and beautifying USB flash disk.

In sum, the USB flash disk that the utility model embodiment provides, be electrically connected by electric contact terminal group and the memory module with bending structure; The electric contact terminal group is arranged in supporter, and an end is revealed in the boss upper surface and forms traditional USB joint, and the other end and Micro-USB joint or Mini-USB joint are electrically connected.Electric contact terminal group one end is realized usb function, the other end and Micro-USB joint or Mini-USB joint are electrically connected realizes Micro-USB interface or Mini-USB interface function, make USB joint and Micro-USB joint or Mini-USB joint with memory module, set up and be electrically connected simultaneously, when thereby USB flash disk has traditional USB joint concurrently, can also provide Micro-USB joint or Mini-USB joint to use, the use of USB flash disk is more flexible, easy to carry and cost is lower.

The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
