Abstract

The utility model discloses an encoder pedestal and an encoder using the same. The encoder pedestal comprises multiple groups of terminal hardware sheets and a plastic body wrapped round the terminal hardware sheets. The terminal hardware sheet comprises terminals and brush portions. The brush of the brush portion is higher than the plane of the brush portion because of punch forming. A blank position is disposed under the brush. An extension portion is disposed at one side of the brush portion and is abutted against the bottom surface of the brush portion after bent. The blank position is covered and the plastic body is integrally wrapped round the brush portion and the extension portion. The extension portion is abutted against the bottom surface of the brush portion after bent and the blank position is covered so that the brushes cannot be damaged because of mutual intersection. When the encoder pedestal is applied to the encoder, a bottom cover used for protecting the brushes is not required to be arranged extra. As a result, not only is the integral thickness of the encoder substantially reduced, but also water is easy to prevent while material cost and assembly time are saved.

Description

Second purpose of the present utility model provides a kind of encoder that comprises aforementioned encoder pedestal.

For achieving the above object, the utility model provides a kind of encoder, comprise pedestal, with the pedestal containing cavity in code-disc, the rotating shaft that is inserted in the code-disc centre bore, the shell fragment that is connected to the code-disc wave-formed mouth that touch of brush section, be sheathed in the rotating shaft and be covered on axle sleeve on the pedestal, be arranged in the water proof ring of rotating shaft and shaft room and be positioned at below the pedestal and with the support of pedestal and axle sleeve envelope, wherein, this pedestal is aforesaid encoder pedestal.

The 3rd purpose of the present utility model provides the encoder that another kind comprises aforementioned encoder pedestal.

For achieving the above object, the utility model provides a kind of encoder, comprise pedestal, with the pedestal containing cavity in the code-disc with centre bore that touches of brush section, the shell fragment that is connected to the code-disc wave-formed mouth, be positioned at the code-disc centre bore rotor, be covered on axle sleeve on the pedestal, be inserted in axle sleeve and be connected to rotor rotating shaft, be arranged in the collar of rotating shaft and shaft room and be sheathed in the rotating shaft and with the support of axle sleeve and pedestal envelope, wherein, this pedestal is aforesaid encoder pedestal.

Further, the containing cavity center of pedestal is provided with switch contact in the such scheme, this encoder comprises also and the switch contact of this switch contact dynamic Contact and the silicon rubber cup of push switch contact that this silicon rubber cup and described rotor butt make this encoder strip switching function.

The beneficial effects of the utility model are: the brush section side in the terminal Five-gold-sheet arranges extension, and fit in the bottom surface of brush section after the extension bending, clearance position is covered, like this in the storage transportation of terminal Five-gold-sheet, can be because of the interlaced brush that damages between the brush that stacks successively; By plastic body with brush section and extension whole plastic after; the brush below of encoder pedestal no longer includes through hole; when therefore being applied to this encoder pedestal on the encoder; do not need additionally to arrange one for the protection of the bottom of brush; not only can reduce significantly the integral thickness of encoder; and be easy to waterproof, can also save material cost and the assembling man-hour.
