Embodiment

By describing technology contents of the present invention, structural attitude in detail, being realized purpose and effect, below exemplify specific embodiment and cooperate the graphic detailed explanation of giving.

See also Fig. 1 and Fig. 2, the utility model circumscribed hard disc 1 is made up of elements such as disk drive body 10, disk drive circuit board 20, metal cage 30 and shock-absorbing parts 40.

Disk drive body 10 is horizontally disposed and roughly is rectangular-shaped, on the two sides of disk drive body 10, offer three pivoted holes 11 respectively, disk drive circuit board 20 vertically is provided with and is close to the front end face of disk drive body 10, the affixed external power receptacle 21 of about medium position, USB socket 22 and other electronic circuit component on a surface of disk drive circuit board 20.The interface of supply socket 21 is over against the front end of disk drive body 10, and supply socket 21 is used for the circumscribed hard disc is connected to domestic power supply (figure does not show).The interface of USB socket 22 is over against the front end of disk drive body 10, and USB socket 22 is used for the circumscribed Hard Disk Drive is connected with computing machine (figure does not show) by a USB cable.

As shown in Figures 1 and 2, in the utility model, be rectangular-shaped and horizontally disposed at these disk drive body 10 outside sheathed metal cages 30, and envelope the integral body of disc driver body 10 and disk drive circuit board 20.Described metal cage 30 has a base plate 31, and it is rectangular-shaped and horizontally disposed that base plate 31 is, and the relative both sides of base plate 31 stretch out and are bent to form pair of sidewalls 32 vertically upward, and the front side of base plate 31 stretches out and is bent to form a header board 33 vertically upward.Offer first on the header board 33 and insert mouthful 331, second an insertion mouth 332 and an a pair of screw hole 333.Base plate 31, header board 33 and two side 32 surround a receiving space 34.The top of front wall 33 and both walls 32 forms first catch 35 towards receiving space 34 1 side horizontal-extendings respectively.The front end of side wall 32 vertically extends to form second catch, 36, the second catch, 36 applying front walls 33 towards front wall 33 1 sides.And on side wall 32, offer a pair of spliced eye 321.Also offer some manholes 37 on base plate 31 and the side wall 32.

In the utility model; be installed with shock-absorbing part 40 respectively in the left and right sides of disk drive body 10 in addition; be arranged with shell 50 up and down relatively in disk drive body 10; shake to slow down circumscribed hard disc 1 suffered external force by these shock-absorbing parts 40; unimpeded with the transmission of guaranteeing signal, by the shell 50 that is set in disk drive body 10 outsides each element with protection external connected hand disk 1 inside.
