Abstract
The utility model discloses an interface conversion circuit board of a mobile hard disk, which is provided with an inner interface and an outer interface, and further a force bearing structure, wherein the interface conversion circuit is supported on a casing of the hard disk through one end on the force bearing structure opposite to the opening direction of the outer interface. The utility model transfers the pressure on the inner interface to the force bearing structure when external joints are inserted in the outer interface through arranging the force bearing structure on the interface conversion circuit board, thereby avoiding damaging the inner interface, and protecting the interface conversion circuit board.
Description
Technical field
The utility model relates to circuit board, especially relates to a kind of interface conversion circuit plate of portable hard drive.
Background technology
The interface of portable hard drive is divided into internal interface and external interface.The external interface great majority of popularizing are USB interface, IEEE1394 interface (Fire Wire fire-wire interfaces) etc. at present, and internal interface has PATA interface, SATA interface etc.Internal interface and external interface are by the conversion of portable hard drive interface conversion circuit plate.As shown in Figure 1, interface conversion circuit plate 1 is provided with internal interface 2 and external interface 3, and hard disk 4 is by internal interface 2 connecting interface change-over circuit plates.External interface 3 is connected with other equipment.There is a defective in the structure of this interface conversion circuit plate 1, because external interface 3 is generally hot-plug interface, can bear repeatedly hot plug, often plug.When extraneous joint plugged, the load parts when internal interface 2 is plug will bear pressure.And internal interface is generally PATA or SATA interface, can not bear repeatedly plug, if bear above too frequent pressure acts on, is easy to cause damage, repeatedly after the plug, causes the interface conversion circuit plate to damage easily.
Summary of the invention
Technical problem to be solved in the utility model is to remedy above-mentioned defective, proposes a kind of interface conversion circuit plate of portable hard drive.
Technical problem of the present utility model is solved by the following technical programs.
The interface conversion circuit plate of this portable hard drive is provided with internal interface and external interface.
The characteristics of the interface conversion circuit plate of this portable hard drive are: also be provided with load-carrying construction, an end opposite with the external interface opening direction of described load-carrying construction is supported on the housing of hard disk.
Described load-carrying construction is a bearing column, and an end opposite with the external interface opening direction of bearing column is supported on the shell of portable hard drive.
Described bearing column comprises two, is separately positioned on the position of internal interface both sides on the interface conversion circuit plate.
The beneficial effect that the utility model is compared with the prior art is: by on the interface conversion circuit plate load-carrying construction being set; pressure when externally interface plugs with extraneous joint is transferred on the load-carrying construction on the interface internally; thereby avoided the damage internal interface, protected the interface conversion circuit plate.
Description of drawings
Fig. 1 is the existing portable hard drive interface conversion circuit composition that hardens;
Fig. 2 is the structure chart of the utility model embodiment.
Embodiment
The interface conversion circuit plate of a kind of portable hard drive as shown in Figure 2, interface conversion circuit plate body 1 is provided with internal interface 2, external interface 3 and load-carrying construction.
Load-carrying construction is two bearing columns 5 that are arranged on the interface conversion circuit plate body 1, are positioned at internal interface 2 both sides.Each bearing column 5 extends along the opening direction of internal interface 2, and this direction is opposite with the opening direction of external interface 3.When internal interface 2 is connected with hard disk main circuit board 4, the length that bearing column 5 extends makes the end face 501 of one end just in time be supported on the force-bearing piece on the hard disk shell, like this when extraneous joint inserts external interface 3, pressure acts on the end face 501, avoid internal interface 2 to bear pressure, avoided damaging the interface conversion circuit plate; The length of bearing column 5 extensions has simultaneously also been controlled the insertion depth of main circuit board 4 in internal interface 2, helps protecting internal interface 2.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For example: externally under the situation that the opening direction of interface 3 is vertical with the opening direction of internal interface 2, bearing column also can be arranged on the opposite position of the opening direction with external interface 3 of interface conversion circuit plate body 1, the pressure when plugging to bear extraneous joint.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
Claims (3)
