We know, current many electronics trackers or electronics are establishedStandby all towards miniaturization development, this development trend forces and is positioned at its inner electromechanical compo (as angular transducer) and also wantsAnd then diminish, but the volume of above-mentioned angular transducer is larger, cannot adapts to again the development trend of miniaturization, be embodied in:1, from radially: 1. rotating shaft 104 right-hand members will be connected with outside parts conventionally, and its diameter is generally 3mm, and turnsAxle 104 left ends are without coordinating with exterior part, and its diameter is also made into 3mm, and this can increase undoubtedly and is contained in rotating shaft 104 left endsThe radial dimension of corresponding parts (as insulation lining seat 100 and conducting ring 101); 2. the revolving force of rotating shaft 104 is by trundle103 and insulation lining seat 100 pass to brush 110, be the intensity that ensures insulation lining seat 100 perisporiums, prevent its transmit movingWhen power, be transmitted pin to twisting off, it is thicker that the perisporium of insulation lining seat 100 is generally all produced, correspondingly, and conducting ring 101Diameter is also along with becoming large; 3. annular protrusion 108 occupies larger radial space; 4. be positioned at 102, the screw of outer cover 111 outsidesPortion also can occupy certain radial space; 2, from Analysis of Axial: stop that with circlip 112 insulation serves as a contrast seat 100 and deviates from meetingThe axial length that increases rotating shaft 104, causes and occupies certain axial space.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of small volume, the angular transducer of compact conformation.
Technical solution of the present invention is that a kind of angular transducer with following structure is provided: comprise rotating shaft, base,One binding post, the second binding post, the 3rd binding post, resistive element, brush, conducting ring, insulation lining seat and cover on resistive element,Brush, conducting ring, the outside outer cover of insulation lining seat, rotating shaft is contained on base by bearing, and resistive element left side is provided with resistanceLayer, resistive layer is the annular with opening, and the opening two ends of resistive layer are electrically connected with the first binding post and the 3rd binding post respectively,Brush one end is pressed on resistive layer, and the brush other end is fixedly connected with conducting ring, conducting ring be enclosed within insulation lining seat upper and with insulationLining seat is bonding, and insulation lining cover for seat is at rotating shaft left end, and the second binding post is brushed silk by ring and is electrically connected with conducting ring, wherein, and rotating shaftLeft end diameter is less than right-hand member diameter, and insulation lining seat is bonding with rotating shaft left end, and resistive element right-hand member is provided with annular boss, the first binding post,The second binding post and the 3rd binding post are all contained on annular boss, and annular boss right-hand member and base left end are bonding, outer cover right-hand member and the endSeat left end is bonding.
Angular transducer of the present invention, wherein, rotating shaft left end periphery wall is provided with axial plane, and axial plane is positioned at insulationIn lining seat inner chamber.
Adopt after above structure, compared with prior art, angular transducer of the present invention has the following advantages:
1, from radially: 1. for ensureing that rotating shaft right-hand member and outside parts are connected, the rotating shaft in angular transducer of the present inventionRight-hand member diameter is same as the prior art, is also 3mm, and in the situation that meeting rotating shaft intensity, will be without joining with outside partsIt is less that the rotating shaft left end diameter that closes is made, and be only 2mm, like this, corresponding parts at an upper portion thereof of dress (as insulation lining seat withConducting ring) radial dimension will correspondingly reduce; 2. rely on trundle and insulation lining seat to transmit the rotation of rotating shaft with prior artPower difference, will insulate lining seat of angular transducer of the present invention is bonding with rotating shaft left end, bonding after, insulation lining seat will become with rotating shaftAn entirety, this is transmitting when revolving force, and insulation lining seat will rely on self whole circumferential side wall to carry out transferring power, thereby is giving birth toProduce while making without the strength problem of considering again insulation lining seat perisporium, therefore, the perisporium of insulation lining seat can be made relativelyThin, thereupon, the diameter of conducting ring can correspondingly reduce; 3. with prior art by the first binding post, the second binding post and the 3rd wiringPost is contained on the annular protrusion that base left end is provided with, and then resistive element is contained on the step of annular protrusion inner chamber different, thisBright angular transducer is directly contained in by the first binding post, the second binding post and the 3rd binding post the annular boss that resistive element right-hand member is provided withUpper, then by bonding to annular boss right-hand member and base left end, like this, angular transducer of the present invention has saved original base left end and has establishedSome annular protrusion wall thickness, radially take up room thereby effectively reduce it; 4. by outer cover directly and base is bonding has saved former screwThe radial space that head is occupied;
2, from Analysis of Axial: insulation lining seat and rotating shaft left end be bonding saves an original circlip that stops that insulation lining is deviate from, therebyThe axial length that effectively shortens rotating shaft, reduces axially to take up room. In sum, the volume of angular transducer of the present invention has obtainedEffectively reduce, after volume reduces, the each several part structure of invention angular transducer will become compacter, and this has adapted to miniaturizationDevelopment trend.
The setting of axial plane can, after insulation lining seat is bonding with rotating shaft, further ensure the reliability of its connection, prevents insulation liningBetween seat and rotating shaft, there is skidding.
