Second object of the present invention is to provide a kind of encoder comprising afore-mentioned code device pedestal.
For achieving the above object, the invention provides a kind of encoder, comprise pedestal, the code-disc touched with the brush portion in pedestal containing cavity, the rotating shaft being inserted in code-disc centre bore, be connected to code-disc wave-formed mouth shell fragment, be sheathed in rotating shaft and be covered on axle sleeve on pedestal, be arranged in the water proof ring of rotating shaft and shaft room and be positioned at below pedestal and by the support of pedestal and axle sleeve envelope, wherein, this pedestal is aforesaid encoder pedestal.
3rd object of the present invention is to provide the encoder that another kind comprises afore-mentioned code device pedestal.
For achieving the above object, the invention provides a kind of encoder, comprise pedestal, with the code-disc of the band centre bore that touches of brush portion in pedestal containing cavity, the shell fragment being connected to code-disc wave-formed mouth, be positioned at the rotor of code-disc centre bore, the axle sleeve be covered on pedestal, be inserted in axle sleeve and be connected to rotor rotating shaft, be arranged in rotating shaft and shaft room collar and to be sheathed in rotating shaft and by the support of axle sleeve and pedestal envelope, wherein, this pedestal is aforesaid encoder pedestal.
Further, in such scheme, the containing cavity center of pedestal is provided with switch contact, this encoder also comprises the silicon rubber cup of switch contact with this switch contact dynamic Contact and push switch contact, and this silicon rubber cup abuts with described rotor, makes this encoder strip switching function.
Beneficial effect of the present invention is: arrange extension in the side, brush portion of terminal Five-gold-sheet, and after extension bending, fit in the bottom surface in brush portion, clearance position is covered, like this in the storage transportation of terminal Five-gold-sheet, between the brush stacked successively, brush can not be damaged because of interlaced; By plastic body by overall to brush portion and extension plastic after; through hole is no longer included below the brush of encoder pedestal; when therefore this encoder pedestal being applied on encoder; do not need additionally to arrange a bottom for the protection of brush; not only can reduce the integral thickness of encoder significantly; and be easy to waterproof, material cost can also be saved and assemble man-hour.
