It is all located in shell 35.Being provided with electric connecting terminals (being not drawn in the drawings) on shell 35, shell 35 is preferably by plastics institute
Formed.
Contact mechanism includes the fixed contact therefor 39 with center through hole 396 and has the mobile contact of center through hole 381
Part 38, wherein, movable contact 38 is positioned at the top of fixed contact therefor 39, and with fixed contact therefor 39 at intervals.
In the present embodiment, movable contact 38 is formed by metal material, movable contact 38 and fixed contact therefor 39 be separated by away from
From about 3.5 millimeters.
Fixed contact therefor 39 includes annular plate 395 and the public contact 390 being arranged on annular plate 395 and four
Stepping contact 391,392,393,394, wherein, annular plate 395 is formed by insulant, public contact 390 and four
Individual stepping contact 391,392,393,394 is all formed by metal material.
Indexing rotating mechanism 30 is positioned on calutron 29, and indexing rotating mechanism 30 includes outer tube 40, rotation bar 41, draws
Bar 42, hollow pipe 43 and contact spring 37, wherein, pull bar 42, hollow pipe 43 and contact spring 37 are all located in outer tube 40, rotate
Bar 41 has part to be positioned at outer tube 40, and the upper bottom portion of outer tube 40 is fixed with shell 35.
Wherein, rotating bar 41 is the body of rod with the first ratchet 411, and pull bar 42 has the second ratchet 421, fin 422 and
The hollow inner edge recessed from bottom, hollow pipe 43 has the 3rd ratchet 432, guide groove 431 and central authorities' pore 433, rotates bar 41
Upper end pivot be placed on the hollow inner edge of pull bar 42, rotate in the tubular connector 30 that calutron 29 is stretched in the lower end of bar 41,
Rotating bar 41 pass the center through hole 381 of movable contact 38 and fix with movable contact 38, pull bar 42 pivot is placed on hollow pipe
In the central pore 433 of 43, the fin 422 of pull bar 42 is positioned in the guide groove 431 of hollow pipe 43, in order to pull bar 42 is relative to hollow
Pipe 43 can slide along guide groove 431 direction.It is true that fin 422 carries out mating use with guide groove 431, beneficially pull bar 42 with
Location between hollow pipe 43.
In the present embodiment, the quantity of the first ratchet 411 is 4, and the quantity of the second ratchet 421 is 8, the 3rd ratchet
The quantity of 432 is also 8.
The upper end of contact spring 37 is connected with the upper bottom portion of outer tube 40, and the lower end of contact spring 37 contacts with pull bar 42.
Contact spring 37 provides downward elastic force to pull bar 42, and this elastic force can pass to movable contact 38 by rotating bar 41.
Calutron 29 includes coiling framework 32, be wound on coiling framework 32 magnet exciting coil 34 and coiling framework 32
The fixed iron core 31 that contacts, movable core 36 and the tubular connector 30 being connected with movable core 36, movable core 36 wraps
Including the cylinder 362 of the medium pore position being positioned at coiling framework 32 and be positioned at the stripe board 361 of cylinder 362 upper end, tubular connects
Part 30 contacts through the center through hole 396 of fixed contact therefor 39 with rotating bar 41.
The bottom of shell 35 is provided with back-moving spring 33, the upper end of this back-moving spring 33 and the cylinder of movable core 36
362 contact, in order to provide elastic force upwards for movable core 36.
When the magnet exciting coil 34 of calutron 29 does not has input current, the movable contact 38 of this many gears electromagnetic switch
The position shown in Fig. 1 it is in, at this moment movable under the common effect of the elastic force of the elastic force of contact spring 37 and back-moving spring 33
Contact 38 with fixed contact therefor 39 at intervals, makes many gears electromagnetic switch be off.
It is then turn on the electric current of magnet exciting coil 34, magnetically-actuated movable core 36 He produced by the electric current of magnet exciting coil 34
The tubular connector 30 fixing with movable core 36 is the most for linear motion, at this moment pull bar 42, rotate bar 41 and with rotate bar
41 fixing movable contact 38 also move downward under the elastic force effect of contact spring 37, make movable contact 38 connect with fixing
A stepping contact in the public contact 390 of contact element 39 and four stepping contacts 391,392,393,394 contacts,
So that many gears electromagnetic switch is in the on-state of a certain gear；Then interrupt the electric current in magnet exciting coil 34, at this moment by
In losing magnetic force produced by electric current, movable core 36 and the tubular connector 30 fixing with movable core 36 are at back-moving spring
Under the elastic force effect of 33 the most for linear motion, and promote the movable contact 38 fixing with rotating bar 41 and fixed contact therefor 39
Separate, make many gears electromagnetic switch be returned to off-state.
In a word, successively connect and interrupt the electric current of magnet exciting coil 34, make movable core 36 carry out back and forth reciprocal straight
Line moves, and in this linear reciprocating motion back and forth, rotates the first ratchet 411 of bar 41 and the second ratchet of pull bar 42
421 and the 3rd ratchet 432 of hollow pipe 43 jointly coordinate, make rotation bar 41 rotate a low-angle around axis Z, owing to movably connecing
Contact element 38 is fixed with rotating bar 41, and such movable contact 38 also rotates a low-angle with rotation bar 41 around axis Z.In this reality
Executing in example, movable contact 38 and rotation bar 41 are rotation direction ω shown in Fig. 3 around the direction that axis Z rotates.
It is again switched on the electric current in magnet exciting coil 34, mobile contact after connecting the most afterwards and interrupting the electric current of magnet exciting coil 34
Part 38 will contact with fixed contact therefor 39 again, owing to movable contact 38 is relative at the upper electricity once connecting magnet exciting coil 34
During stream, the most in rotational direction ω have rotated a low-angle, and it is movable that this movable contact 38 contacts with fixed contact therefor 39
Another in the public contact 390 of contact 38 and fixed contact therefor 39 and four stepping contacts 391,392,393,394
Individual stepping contact contacts.It can easily be seen that constantly interrupt and the electric current connected in magnet exciting coil 34, movable contact 38 can be made
Four stepping contacts of circulating contact 391,392,393,394, thus realize between multiple gears of many gears electromagnetic switch
Cycling switch works.
While there has been shown and described that it is presently considered to be preferred embodiments of the invention, but it will be apparent that this area
Technical staff can carry out various changes and improvements, the scope of the present invention limited without departing from appended claims.
