Technical field
The present invention relates to a kind of trigger mechanism, comprise a moving contact that can lock, a push rod and a frizzen.The invention still further relates to a kind of switching device of being furnished with this trigger mechanism in addition.
Background technology
Fusing conductive contact surfaces in the time of for example can using magnetic trigger itself or magnetic triggering system to prevent that current strength is big in described switching device is perhaps worked as and is guaranteed reliable the disconnection when electric arc that is produced may damage described switching device.Since long triggered time may the limiting protecting switch range of application, so the triggered time should be short as far as possible.
Described magnetic trigger mechanism both can be used for normally closed interlock, also can be used for normally open contact.Below mainly as a reference with normally closed interlock.The moving contact of described normally closed interlock is locked among the contact position that final formation electrically contacts.In other words, the push rod of described trigger mechanism must at first be run into described frizzen, and described frizzen unlocks, and will control motion then and pass to described moving contact from described push rod.Exist to a certain extent from described push rod via of the chain effect of described frizzen until described moving contact.Don't fail to comprise described frizzen, especially described moving contact can not move under lock-out state.
DE 102004040288B4 is disclosed to be exactly a kind of trigger mechanism with above-mentioned triggering chain.
Summary of the invention
The objective of the invention is to set forth a kind of can the realization and can also guarantee the trigger mechanism of transfer function power in the best way than short triggered time, while.
Adopt the described trigger mechanism of beginning, can realize this purpose, but the push rod in the described trigger mechanism is the described frizzen that is used for the release moving contact of actuating both, also can be used to the described moving contact of actuating itself, method is to control first acting surface of motion stage by push rod at first of described push rod to directly act on described frizzen, second controls second acting surface of motion stage by described push rod and directly acts on described moving contact at it then.Employing has a kind of switching device of trigger mechanism of the present invention, equally also can realize this purpose.
The difference of the action principle of trigger mechanism of the present invention and traditional push rod-frizzen-moving contact effect chain is: have and can directly act on trigger mechanism, also can directly act on the push rod of moving contact.But pay special attention to the order of transfer function power because must at first guarantee power is passed to described frizzen so that described push rod continue to act on described moving contact make contact open or closure before can guarantee the described moving contact of timely release.
First of described push rod is controlled motion stage and is acted on described frizzen by its first acting surface.After the actuating frizzen, described frizzen will unclamp the described ratchet that is used for locking moving contact.Second of described push rod is controlled motion stage can act on described moving contact by direct again second acting surface by described push rod equally.Directly realize this two kinds of effects, just both acted on frizzen, act on moving contact again by the acting surface of described push rod.
Described according to a kind of useful form of implementation, first acting surface and second acting surface of described push rod take shape on the different parts of described push rod in the actuating direction.So both can guarantee to stagger time effect, also take into account frizzen and moving contact position simultaneously with respect to the respective action face in frizzen and moving contact.
More useful is to move described push rod by a solenoid.Can produce the operating physical force that is used for twice mechanism by coil.
Help when the described frizzen of actuating, unclamping the ratchet that links to each other with described moving contact machinery.According to the arrangement form of trigger mechanism parts of the present invention, be not by described push rod at one-sided actuating frizzen, but the acting surface of a plurality of symmetric arrangement is arranged, can reduce of tension force and the friction of described frizzen like this in described device outer case inside.
Because described push rod directly acts on described frizzen and moving contact, therefore help to shorten the triggered time greatly, as long as especially apply less acceleration energy, so acting surface is less.
Description of drawings
About other useful form of implementation of the present invention and advantageous embodiment form of implementation, can consult description of drawings and dependent claims.
Relevant drawings is as follows:
Accompanying drawing 1 is the partial 3 d cutaway view before the moving contact of described trigger mechanism after acting on described unclamping,
Accompanying drawing 2 be this trigger mechanism shown in the accompanying drawing 1 after the locking not by the 3-D view under the state of actuating, and
Accompanying drawing 3 is this trigger mechanism and coil and the 3-D view of counterpart contact before the moving contact that acts on after unclamping shown in the accompanying drawing 1.
Accompanying drawing 1 be depicted as this trigger mechanism by described push rod 2 via the of short duration partial 3 d cutaway view that acts on (phase I) after the described frizzen 3 of two acting surfaces 8.Described push rod 2 acts on described frizzen 3 along direction of motion B, and it is crooked to avoid described frizzen 3 to occur by the symmetry effect of described acting surface 8, perhaps avoids increasing friction.In principle as long as a pair of acting surface 8,13 just is enough to the described frizzen 3 of actuating.
Owing to caused release by the described frizzen 3 of actuating, and the acting surface 9 of described push rod 2 has moved forward to described moving contact 1, and (second stage) acts on acting surface 14 by described push rod 2 or the acting surface 9 by described push rod self and move described moving contact in further motion process.
Accompanying drawing 2 be this trigger mechanism shown in the accompanying drawing 1 after the locking not by the 3-D view under the state of actuating.This state is equivalent to the basic status of this trigger mechanism.Hereto both the motoricity of described acting surface 8 is not passed to the acting surface 13 of described frizzen 3, also motoricity is not passed to the acting surface 14 of described moving contact 1 from the acting surface 9 of described push rod 2.
Can find out in the home position of the described frizzen 3 that is used for unclamping or locks moving contact a ratchet 4 is arranged.But the described push rod of its actuating 2 is away from home position.Described push rod 2 moves the described frizzen below this ratchet 4, away from the sphere of action of this ratchet 4.The first actuating stage finished, and this trigger mechanism of release just is in its terminal intermediateness that arrives shown in accompanying drawing 1 and accompanying drawing 3.
Accompanying drawing 3 comprises 3-D view before a coil 5 and the described moving contact 1 of a counterpart contact 6 after acting on release for this trigger mechanism shown in the accompanying drawing 1.Contact-making surface 7 by described moving contact 1 connects described counterpart contact 6.In motion process subsequently, described push rod 2 will interrupt this connection by described acting surface 9.
By the sphere of action of the described frizzen 3 of actuating away from described ratchet 4, thus the power transmission between the elimination associated components, and unlock.
Can find out that described frizzen 3 has left described ratchet 4.This trigger mechanism is in the changeover portion between stage 1 and stage 2 just, and described coil 5 drives described push rod 2 to be continued to move forward, and continues the acting surface 14 of the described moving contact 1 of actuatings by described acting surface 9, makes that closed contact is opened on the described contact-making surface 7.
Described push rod 2 both can carry out release by described frizzen 3, also can make described moving contact 1 move., when making described push rod 2, should note the spacing between described acting surface 8 and 9 in order to guarantee the only described moving contact 1 of actuating after release.If release needs the regular hour, then the spacing of these acting surfaces is bigger, will consider described moving contact 1 and the arrangement of frizzen 3 within described trigger mechanism simultaneously.
