Abstract

The utility model provides a fail-safe device for the computer extract box, which cut a sunken guide groove at the one side wall end edge of the inner box, so as to reach insert fail-safe function when the inner box into the outside frame because of the outside frame. A block point is arranged at the place which faces to corresponding guide groove in the converted side wall of the outside frame, thereby making the guide groove pass through the block point, and making the inner box smoothly combine and separate with the outside frame.

Description

Computing machine extracts the error prevention device of box

Technical field

The utility model relates to the mechanism in a kind of computing machine extraction box, refers in particular to the tool error prevention device that a kind of computing machine extracts box.

Background technology

Press the fast development of Information of Science and Technology, make computer hardware equipment produce change for adapting to various variations, for example the hard disk (hard disk) of early stage computing machine all is installed in the host shell of computing machine.Be the preservation or the backup of data, even consider based on the portability and the security of confidential data, so-called extraction box (mobile rack), for example the hard disk abstraction box is to be achieved along with demand, and it is greatest convenient to allow the user obtain.In fact, can be placed in the data storage device of internal box, except that aforesaid hard disk, still comprise hifd machine (ZIP disk drive), MO (Magneto-optical diskdrive), magnetic tape station or flash memory card reader ... Deng, make that the practicality that extracts box is more broad.

But computing machine extracts the start principle of box, be with internal box when the outer framework of turnover, with two corresponding interior casket connector and outer gimbal connector intercalation each other and the disengagings that are provided with, so that the connecting and disconnecting of formation electrical signal.But the user is if be inverted internal box accidentally, and the outer framework of insertion, and both connectors are formed when docking, then may be, so that the lighter causes short circuit because of the dislocation of signal pin position, severe patient even cause burning of data storage device, make the data of preserving or backing up, be destroyed overnight because of mispluging.In addition, in the interior casket specification of other producers because the difference of the signal definition of pin position of interior casket connector, if when carrying out intercalation with the outer framework of different manufacturers hastily, also may be, and cause the facts of aforesaid short circuit or damage to take place because of the conflict of electrical signal.

The utility model content

The error prevention device that this case fundamental purpose is to provide a kind of computing machine to extract box can prevent internal box maloperation during framework outside turnover.

For achieving the above object, a kind of computing machine that the utility model provides extracts the error prevention device of box, and it is to open a recessed guide groove at a sidewall ora terminalis of an internal box, so that when being intercalated in outer framework by internal box, can adapt to outer framework, thinks mistake proofing.And side wall inner surface in opposite directions that should outer framework is able to by the retaining point guide groove to should the prominent retaining point of establishing in guide groove position, make internal box and outer framework smoothly combination with separate.But when the sidewall ora terminalis of internal box touches the retaining point of outer frame side wall, then represent this internal box, be the internal box of other producers perhaps, and can't make internal box combine with outer framework for being inverted.

Wherein this retaining point is the side wall inner surface that is shaped in outer framework; Perhaps this retaining point is to be incorporated into the default cinclides of outer frame side wall inner face with a cylindrical body.

Description of drawings

Fig. 1 extracts the three-dimensional exploded view of box for the utility model computing machine;

Fig. 2 for the utility model desire in conjunction with the time stereographic map;

Fig. 3 can't be intercalated in the synoptic diagram of outer framework for the utility model internal box.

Embodiment

For further disclosing the concrete technology contents of this case, at first see also graphic.

To shown in Figure 2, basically, it is by an internal box 1 that the computing machine of this case extracts box, and an outer framework 2 combines as Fig. 1.

Wherein, internal box 1 is a box body, and is ccontaining and fix a data storage device in it, its back side is provided with casket connector 11 in, as shown in the figure, is the IDE interface connector of one 50 pin positions (pins), only not as limit, it also must be the signal and the power connector at SATA interface.And the creative feature of this case is that a sidewall 12 ora terminalis of this internal box 1 open a recessed guide groove 121, and another sidewall 13 does not then have the setting of this guide groove.

Outer framework 2 is a hollow frame, be installed in the device space of main frame, corresponding internal box 1 size in its hollow frame chamber, for its turnover, casket connector 11 forms intercalation and disengaging with the outer gimbal connector 21 of being located at outer framework 2 back sides in it and make, and this outer gimbal connector 21 is to be oppositely arranged according to the interface of interior casket connector 11.And the creative feature of this case is, the sidewall 22 of this outer framework 2 is with respect to the prominent retaining point 221 of establishing in guide groove 121 positions of the sidewall 12 of internal box 1, and it can pass through for this guide groove 121, and internal box 1 can successfully be combined as shown in Figure 2 with outer framework 2.Wherein, when this retaining point 221 is implemented, be one-body molded with the sidewall 22 of outer framework 2, only not as limit, this retaining point 221 can also a cylindrical body be incorporated in these sidewall 22 default cinclides 222, can obtain identical effect.

See also Fig. 3, if internal box 2 is when being inverted, the ora terminalis of its another sidewall 13 is not owing to open guide groove, so that its ora terminalis can touch retaining point 221, and then forms the backstop function, to obtain to prevent to misplug effect.In like manner, the sidewall ora terminalis of the internal box of other producers does not also have the guide groove setting, also can push and can't go because of touching retaining point 221 again.

This case discloses, and is a kind of of preferred embodiment, and the patent right category of this case is not all taken off in Ju Bu change or modification and come from the technological thought of this case and be the technology that the people was easy to know by inference of haveing the knack of this skill such as.

Claims

1, a kind of computing machine extracts the error prevention device of box, it is characterized in that, opens a recessed guide groove at a sidewall ora terminalis of an internal box.

2, computing machine according to claim 1 extracts the error prevention device of box, it is characterized in that, side wall inner surface in opposite directions that wherein should outer framework is established one and kept off point should the guide groove position prominent.
