Pit position comes in contact and weares and teares, and reaching during the position of engagement is then that point on nearest section produces contact and abrasion,
The support zone rotating is contact, and now between sliding sleeve and positioning disk, contact point fretting wear is big, and moment and feel and return
Position performance is also unstable.
Content of the invention
Technical problem to be solved in the utility model is for above-mentioned problem, provides a kind of shunting switch to touch
Head gear positioning device, structure setting is more reasonable, serviceability is more excellent.
This utility model solves above-mentioned technical problem and be employed technical scheme comprise that：A kind of tapping switch contact gear positioning
Device, including positioning disk and axial elasticity sliding sleeve, described positioning disk is installed on switch base, and described axial elasticity sliding sleeve is set in
Setting corresponding with positioning disk in switch spindle, circumferentially corresponding contact on the positioning disk end face corresponding with axial elasticity sliding sleeve
Gear setting positioning pit or positioning boss, setting positioning boss or positioning on the axial elasticity sliding sleeve end face corresponding with positioning disk
Hole, with positioning pit or the positioning boss phase configuration of positioning disk it is characterised in that positioning pit on positioning disk and axial elasticity sliding sleeve
And the cross sectional shape of positioning boss is trapezoidal or other surface compositions, it is in radially fan shape or radial from the inside to the outside.
By such scheme, the axial direction that described axial elasticity sliding sleeve includes being sleeved in switch spindle and being connected by bearing pin is slided
Set, switch spindle has axial slide, bearing pin pass through axial slide and can slide vertically, axial slide outboard end and
It is provided with compression spring between bearing pin, described locating convex block or positioning pit are set in the medial extremity of axial sliding sleeve.
By such scheme, the outboard end of described compression spring is provided with briquetting, and described briquetting and moving contact supporter pass through
Equipotential line short circuit.
By such scheme, described positioning disk and axial sliding sleeve are by strengthening nylon or engineering plastics are made.
By such scheme, described positioning disk and switch base can be formed in one structure.
The beneficial effects of the utility model are：1st, provide a kind of gear positioning device for tapping switch contact, setting is in radiation
After the positioning boss of shape face cooperation and hole, under the effect of axial elasticity sliding sleeve, positioning boss and hole list comprehensively in shift process
Face contacts, and the initial moment of switch gear shift operation is larger and have feel, also has the feel that playbacks by force very much when reaching another gear, this
Feel can be clearly felt that during manual operation switch on operating mechanism outside in transformator for the sample, especially install in operating mechanism
When from external energy feel internal switch body positioning accuracy, increase substantially installation and debugging precision, optimize switch
Serviceability, enhance the stability of operation, also allow for inorganic with the semi-finished product performance of transformator contact performance in switch
Detection under structure state；2nd, the cooperation of the fan-shaped tooth surface in positioning boss and hole makes comprehensive engagement between localizer boss and positioning pit
With cooperation, such moment good stability, wearability is good, life-span length；3rd, structure is simple, especially makes cage type switch dynamic/static contact contact
Positioning precision is lifted, and the switch accuracy of manufacture requires to reduce with cost, and contact is more reliable；4th, structure setting rationally, is adopted
With nonmetallic making positioning disk and axial sliding sleeve, metal removal powder pollution transformer oil can be avoided, improve the safety of switch
Serviceability；5th, this utility model can be used for cydariform, tubular and tubular switch, including single-phase, multiphase shunting switch, especially suitable
Should be in operating mechanism and the not integral Split switch of Switch main body.

Specific embodiment
For more fully understanding this utility model, with reference to the accompanying drawings and examples this utility model is further retouched
State.
Fig. 1-4 is an excitation-free cage type tapping switch, and insulator 2 internal upper part is provided with flange 17, under install switch base 10,
Insulation is circumferentially installed on static contact 3 in vivo, installs switch spindle 6, pacified by supporter 5 in the middle part of switch spindle in the middle of switch base
If moving contact 4, moving contact and static contact phase configuration；Install fixing positioning disk 9 in switch base upper end, circumferentially right on positioning disk
Answer contact gear setting positioning pit 16, positioning pit is circumferentially installed in the upper surface of positioning disk, and positioning pit section is trapezoidal faces,
One axial elasticity sliding sleeve is set with the main shaft above positioning disk, axial elasticity sliding sleeve includes being sleeved in switch spindle and passes through pin
The axial sliding sleeve 8 that axle is connected, switch spindle has axial slide 14, and bearing pin passes through axial slide and can chute slide vertically
Dynamic, it is provided with compression spring 13 between axial slide outboard end and bearing pin, locating convex block 11, positioning are set in the lower end of axial sliding sleeve
Projection is correspondingly arranged as trapezoidal projection, with positioning pit trapezoidal hole phase configuration, trapezoidal angle matches.Additionally, switch spindle
Upper end is connected with operating mechanism 1, drives switch spindle rotation, the gearshift being switched by operating mechanism.
For ensureing spring band current potential, spring outwards end is provided with briquetting 15, and passes through isoelectric level with moving contact supporter
Line 7 short circuit and realize isoelectric level.When switch spindle rotates, drive moving contact and axial sliding sleeve synchronous axial system, quiet mill during startup
Damage moment larger, positioning boss and positioning pit occur axial displacement under spring pressure, relatively slide at flank engagement, produce resistance
Moment, when reaching near new contact position, when positioning boss progressively falls into new definition hole under spring pressure release,
Produce a playback moment forward, and eliminate driving error and help dynamic/static contact positioning more accurate, once positioning pit with convex
Platform is at a fully engaged, and gearshift completes, and is larger resistance torque when being now rotated further by forward again, just can aware switch move from mechanism
Static contact positioning puts in place, lifting operation reliability.In embodiment, compression spring also can use extension spring, makes positioning pit and positioning boss
Engagement.Positioning disk can also be fixed on above flange or following.Positioning pit can be arbitrarily bent with the mating surface of positioning boss
Face, but be radial on a radius, section is linearly amplified.Positioning disk and axial sliding sleeve are by strengthening nylon or engineering plastics system
Become, positioning disk can be integrally formed with switch base.
This device is applicable in other no selecting switch of excitation tubular, strip-shape tap switch and load ratio bridging switch.
