Background technology
Micro-camera device has been widely used on mobile phone and the notebook computer, and micro-driving motor wherein (also being the lens drive motors) is also done less and less.
Traditional micro-driving motor generally comprises housing, Upper gasket, upper spring sheet, lens carrier, magnetite assembly, coil block, lower gasket, lower spring chip module and insulator foot; The lower spring chip module comprises two conduction lower spring sheets, leaves the gap between described two lower spring sheets to form open circuit.Described lower some dish is pushed down the outer ledge of lower spring chip module, thereby conduction lower spring sheet is crimped on the base.
Traditional product is for fear of two lower spring sheet short circuits, so the employing plastics are made lower gasket, because the lower gasket size is little, thickness is only about 0.5mm, so intensity is lower, in manufacturing and assembling process, be very easy to damage, even the pressure that is difficult to provide enough compresses the lower spring sheet; Also has another situation, in order to improve intensity, do the thickness of lower gasket thicklyer, between 1mm to 2mm, thereby increased the whole height of micro-driving motor, but the height that for this reason increases, for micro-driving motor, sizable size, the integral thickness of the electric equipment products such as mobile phone that this product of the final employing of direct impact is made.
Summary of the invention
The purpose of this invention is to provide a kind ofly can provide sufficient intensity, not fragile, the base assembly that is used for micro-driving motor of Effective Raise yields.
The technical scheme that realizes the object of the invention is: a kind of base assembly for micro-driving motor comprises insulator foot, two conduction lower spring sheets, is used for conduction lower spring sheet is crimped on crimp on the base; Leave the gap between described two lower spring sheets; Described crimp comprises frame shape shim body and the insulating barrier between lower spring sheet upper surface and shim body lower surface that adopts metal material to make.
In the such scheme, described insulating barrier is by the shim body outer surface being carried out formed insulating barrier after the chemical treatment.
In the such scheme, described insulating barrier is the insulating barrier that forms after coating processes is processed by carrying out at the shim body outer surface.
In the such scheme, described insulating barrier is the plastic layer that forms at the shim body outer surface by Shooting Technique.
In the such scheme, described insulating barrier is to mould layer by the electrophoretic painting mode in the plating that the shim body outer surface forms.
In the such scheme, described insulating barrier is positioned on bottom surface, bottom surface and the two sides or whole outer surface of shim body.
In the such scheme, described insulating barrier is a plastic insulation plate of making separately.
The present invention has positive effect:
In the product of the present invention, described crimp comprises frame shape shim body and the insulating barrier between lower spring sheet upper surface and shim body lower surface that adopts metal material to make.This structure is made shim body by the employing metal, and avoids two lower spring sheet short circuits by insulating barrier, thereby under the prerequisite that keeps the lower gasket size, has effectively guaranteed intensity and the result of use of lower gasket; And because intensity is higher, in manufacturing and assembling process, be not easy to damage, the Effective Raise yields, and can provide enough pressure to compress the lower spring sheet.
