Description
Technical field
The utility model is related to electrical equipment, specifically a kind of tap switch.
Background technology
Tap switch product is used for the needs for meeting transformer adjustment voltage, and gear shaft and movable contact spring are controlled by operating mechanism
Group movement, is allowed to connect different static contacts, realizes the conversion of different stalls, movable contact spring group includes in the prior art：It is left and right dynamic
Contact, leaf spring and dynamic stent, left and right two movable contact springs are mounted on dynamic stent, and leaf spring offsets with movable contact spring, so as to form elasticity
Clamp structure, left and right two movable contact springs inside clamping static contact.The prior art is switched in gear transfer process, without clear
Shift feeling, this leads to the maloperation of certain customers, generates security risk.
Invention content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of gear clearly tap switch, specifically
Technical solution is as follows：
A kind of special strip-shape tap switch of triangular solid Wound iron-core transformer, it is characterised in that：Including operating mechanism, institute
It states operating mechanism to slide in insulating bar group by gear band carry-over bar, setting movable contact spring group on the rack, in insulating bar group
Static contact is set；The operating mechanism includes handle, and the handle and drive gear and positioning gear are coaxial, drive gear and tooth
Item engages；Positioning gear is abutted with positioning bead, and positioning bead is arranged on the end of spring, and positioning bead and spring are arranged on stent
Locating slot in.
To be further ensured that the clear of gear, movable contact spring plane is rectangle, and cross section is the recessed waveform in intermediate convex both sides,
Static contact is cylinder.
To ensure the synchronization of feel, when the bottom of the tooth of the positioning gear is abutted with positioning bead, convex wave among movable contact spring
Just as when be wrapped in the cylinder of static contact.
When can also be agreed with by setting corrugated radian convex among movable contact spring to distinguish positioning gear and positioning bead
Oscillation Amplitude.
The utility model has the advantages that：Switch has positioning function, clearly gear feel, safety in gearshift procedure
Reliably, gear generation not in place has been prevented.

Specific embodiment
The utility model is illustrated below in conjunction with the accompanying drawings, as shown in the figure, the utility model includes operating mechanism, the behaviour
Make mechanism band carry-over bar 4,6 to slide in insulating bar group, movable contact spring 17 on the rack 4,6 is set, is set in insulating bar group 3,5
Static contact 16；The operating mechanism includes handle 71, and the handle 71 and drive gear 9 and positioning gear 8 are coaxial, drive gear
9 engage with rack 4,6；Positioning gear 8 is abutted with positioning bead 13, and positioning bead 13 is arranged on the end of spring 12, positioning bead and bullet
Spring is arranged in the locating slot 14 on stent 1.
To be further ensured that the clear of gear, 17 plane of movable contact spring is rectangle, and cross section is the recessed wave in intermediate convex both sides
Shape, static contact are cylinder.
To ensure the synchronization of feel, when the bottom of the tooth 10 of the positioning gear is abutted with positioning bead, convex wave among movable contact spring
Shape wave is wrapped in the cylinder of static contact simultaneously.
When can also be agreed with by setting the corrugated radian of movable contact spring intermediate projections to distinguish positioning gear and positioning bead
Oscillation Amplitude.
Act the course of work：The rotation band moving gear of operating mechanism 7, the positioning gear 8 on gear revolve simultaneously with drive gear 9
Turn, positioning the tooth top 11 on gear 8 inside contracts the extruding spring 12 of positioning bead 13, and positioning gear 8 continues to rotate, and tooth top 11 leaves fixed
Position pearl 13, positioning bead 13 slips into rapidly bottom of the tooth 10 under the action of spring 12, while drive gear 9 stirs rack 4,6, moves stent
2 reach the position of needs with movable contact spring 17 under the drive of rack 4,6, during movement, because two movable contact springs, 17 inside is convex
Place's relative spacing is small, and need to increase torsional forces can just move past 16 cylinder high point of static contact, after 17 convex of movable contact spring slips over static contact 16
To next static contact, 17 recess of movable contact spring offsets with static contact cylinder, and there is superpower feel of transferring the files to position work(with gear
Energy.
