Background technology
Reading of contact rotary encoder coded message is that brush by code-disc and contact is accomplished.The pedestal of existing contact rotary encoder mainly is made up of terminal five metals sheet and plastic plastic cement body outside terminal five metals sheet; Terminal five metals sheet mainly comprises terminal and brush portion; If belt switch function; Then also comprise switch contact, the brush of brush portion is higher than the brush facial planes because of punch forming, and the brush below is a clearance position.The encoder pedestal of this structure, its terminal five metals sheet is in the storage transportation, and a plurality of terminal five metals sector-meeting mutual superposition and make brush interlaced are damaged brush easily; When terminal five metals sheet and the injection moulding of plastic cement body, the clearance position under its brush can't injection moulding, and causing the brush subordinate side of pedestal is through hole; Thereby when producing encoder, need below pedestal, install bottom additional, with protection brush structure; This bottom has not only increased the thickness of encoder; And the junction of bottom and pedestal is prone to the slit, is unfavorable for the waterproof of encoder, also needs consume material and assembling man-hour in addition.
Summary of the invention
First purpose of the present invention provides a kind of encoder pedestal.
For realizing above-mentioned purpose, the invention provides a kind of encoder pedestal, comprise some groups of terminal five metals sheets and plastic plastic cement body outside terminal five metals sheet; Terminal five metals sheet comprises terminal and brush portion, and the brush of brush portion is higher than the brush facial planes because of punch forming, and the brush below is a clearance position; There is an extension side of brush portion; Fit in the bottom surface of brush portion after this extension bending, clearance position is covered, the plastic cement body is plastic with brush portion and extension integral body.
Second purpose of the present invention provides a kind of encoder that comprises aforementioned encoder pedestal.
For realizing above-mentioned purpose; The invention 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 portion, 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 the support of pedestal and axle sleeve envelope; Wherein, this pedestal is aforesaid encoder pedestal.
The 3rd purpose of the present invention provides the encoder that another kind comprises aforementioned encoder pedestal.
For realizing above-mentioned purpose; The invention provides a kind of encoder; Comprise pedestal, with the pedestal containing cavity in the band centre bore that touches of brush portion code-disc, be connected to the shell fragment of 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 also comprises the switch contact that dynamically contacts with this switch contact and the silicon rubber cup of push switch contact, and this silicon rubber cup and said rotor butt make this encoder strip switching function.
Beneficial effect of the present invention is: the brush portion side in terminal five metals sheet is provided with extension; And fit in the bottom surface of brush portion after the extension bending; Clearance position is covered; Like this in the storage transportation of terminal five metals sheet, can be between the brush that stacks successively because of the interlaced brush that damages; By the plastic cement body with brush portion 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 the extra bottom that is used to protect brush that is provided with, not only can reduce the integral thickness of encoder significantly; And be easy to waterproof, can also save material cost and the assembling man-hour.
