Embodiment

Fig. 1 is the stereographic map of the external connected hand disk of the utility model one embodiment.Fig. 2 is the explosive view of the external connected hand disk of Fig. 1.Please also refer to Fig. 1 and Fig. 2, the external connected hand disk 100 of present embodiment comprises hard disk main body 110, a plurality of soft elastic component 120 and shell 130.Hard disk main body 110 has a plurality of assembly holes 112, and soft elastic component 120 is configured in respectively in the assembly hole 112.Each soft elastic component 120 has perforate 122, and shell 130 has a plurality of projections 132, and wherein the position of projection 132 corresponds respectively to the position of the assembly hole 112 of hard disk main body 110.Projection 132 inserts perforate 122 respectively and shell 130 and hard disk main body 110 is interfixed.

Shell 130 that it should be noted that present embodiment is made of upper casing 130a and lower casing 130b.When assembling, can earlier hard disk main body 110 be inserted lower casing 130b, and two projections 132 that will be positioned at lower casing 130b insert two corresponding perforates 122 respectively.Then, cover lower casing 130b and hard disk main body 110 is coated jointly by upper casing 130a and lower casing 130b with upper casing 130a again, two projections 132 that also will be positioned at upper casing 130a simultaneously pass two through hole H that are positioned at lower casing 130b respectively and insert two corresponding perforates 122 respectively.

When the external connected hand disk 100 of present embodiment is subjected to external force collision or produces vibrations because of other factors, vibration energy can be passed to each soft elastic component 120 via shell 130, and soft elastic component 120 can absorb to the vibration energy of small part avoids it to be passed to hard disk main body 110.In other words, in the mode that locks shell is fixed in the hard disk main body compared to prior art, and between shell and hard disk main body, dispose elastomeric pad to reach shock-proof effect, present embodiment is with the soft elastic component 120 in the assembly hole 112 of the projection 132 insertion hard disk main bodys 110 of shell 130, assembles in the mode of close-fitting.In order to the soft elastic component 120 that reaches shock-proof effect is to be positioned at assembly hole 112, therefore can't occupy the space between shell 130 and the hard disk main body 110, and make external connected hand disk 100 can have smaller volume compared to existing external connected hand disk.

In addition, in the mode of close-fitting shell 130 is fixed in hard disk main body 110, does not assemble in the mode that locks so do not need to see through screw and screw in addition, and can save built-up time and cost because present embodiment is a elastic deformation by soft elastic component 120.In the present embodiment, the material of soft elastic component 120 can be a rubber, and the material of shell 130 can be metal (for example, the material of shell 130 for example is an aluminium).Yet the utility model is not limited the material of soft elastic component 120 and shell 130, and it can be other suitable material that can reach identical effect.

Please also refer to Fig. 1 and Fig. 2, in the present embodiment, external connected hand disk 100 more comprises circuit board 140.Circuit board 140 is fixed in hard disk main body 110 and is electrically connected to each other with hard disk main body 110, and is coated by shell 130 jointly with hard disk main body 110.In addition, circuit board 140 has transmission plug 142 and USB (universal serial bus) (Universal Serial Bus, USB) plug 144.Circuit board 140 electrically connects by transmission plug 142 and hard disk main body 110.Shell 130 has opening 134, exposes USB (universal serial bus) plug 144 to see through opening 134.Therefore, USB (universal serial bus) plug 144 can electrically connect with the universal serial bus connector (not illustrating) of outside, to carry out the transmission of data with other electronic installation (as mobile computer or desktop PC).

In sum, have soft elastic component in the assembly hole of hard disk main body of the present utility model, shell inserts soft elastic component by projection and assembles with the hard disk main body, and wherein the soft elastic component between hard disk main body and shell has shock-absorbing and fixing effect.Thus, needn't between hard disk main body and shell, dispose elastomeric pad, can make external connected hand disk have smaller volume for shock-absorbing.In addition, interfix, do not assemble in the mode that locks so do not need to see through screw and screw in addition, and can save built-up time and cost because shell and hard disk main body are modes by close-fitting.

Though the utility model discloses as above with embodiment; right its is not in order to limit the utility model; have in the technical field under any and know the knowledgeable usually; in not breaking away from spirit and scope of the present utility model; when doing a little change and retouching, so protection domain of the present utility model is worked as with being as the criterion that claim was defined.
