Abstract

The utility model discloses an electromagnetic transfer switch which includes an electromagnetic loop and a gag bit; a push rod is connected on the gag bit; a detent is hinged on the push rod; one side of the detent is provided with a ratchet wheel; a rotating shaft of the ratchet wheel is provided with a dynamic contact terminal; a plurality of static contact terminals are arranged on the moving tracks of the dynamic contact terminal; compared with the prior art, the electromagnetic transfer switch can remotely realize to control the running and stopping of a motor in a short time with multipoint segment; besides, the power consumption is less when in work, the service life is long and the noise is little.

Description

Solenoid tumbler

Technical field

The utility model relates to electrical equipment control device technical field, especially a kind of multi-position switch of electromagnetic conversion.

Background technology

The break-make of its control contact of existing solenoid tumbler is corresponding with the break-make of controlling electric current in the electromagnet coil, this solenoid tumbler in use its solenoid is switched on for a long time, both wasted electric energy, send noise again, and also can shorten solenoid its life-span under the situation of long-time energising.And this electromagnetic switch in streamline work if stop in the commentaries on classics of the control motor of each post remote multi-point section, its electric wiring is not only arranged very complicatedly, and change-over time is long, consume material is many.

Summary of the invention

The purpose of this utility model is with regard to providing a kind of can stopping in the commentaries on classics of realization control of long-range short time of multipoint segment motor, and is simple in structure, little power consumption during work, and the life-span is long, the solenoid tumbler that noise is little.

In order to address the above problem, the scheme that the utility model adopts is: include solenoid and armature, be connected with a push rod on the described armature, on push rod, be hinged with ratchet, side at ratchet is equipped with ratchet, be connected with moving contact in the rotating shaft of this ratchet, on the movement locus of this moving contact, be provided with a plurality of fixed contacts.

In such scheme, between described ratchet and push rod, can be connected with return spring.

Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:

Because the moving contact of this switch is to be connected in the rotating shaft of ratchet, cooperate a stepwise operation realizing just can controlling moving contact to electric pulse of electromagnet coil with ratchet by the ratchet that is connected with armature, therefore, can be provided with in many places switch independently the commentaries on classics of short time inner control motor stop, and when work little power consumption, life-span is long, and noise is little.

Embodiment

Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:

At Fig. 1, Fig. 2, among the embodiment shown in Figure 3, solenoid 3 is equipped with on the top of support body 1 of the present utility model, armature 2 is housed in solenoid 3, be connected with a push rod 4 on the armature 2, the lower hinge of push rod 4 has ratchet 10, between ratchet 10 and push rod 4, also be connected with return spring 12, side at ratchet 10 is equipped with ratchet 9, this ratchet 9 is fixed on the support body 1 by axle, in the rotating shaft 6 of ratchet 9, moving contact 5 is housed, when ratchet 9 rotated, moving contact 5 was followed ratchet 9 and is rotated together, and the lead-out wire 8 usefulness springs 11 of moving contact 5 are fitted in a side of ratchet 9 and stretch out outside the support body 1.In the bottom of support body 1, be distributed with a plurality of fixed contacts 7 on the movement locus of moving contact 5.

During the utility model work, when solenoid 3 energisings, armature 2 drives push rod 4 and moves downward, and the ratchet 10 that is hinged on push rod 4 bottoms moves downward with push rod 4, rotate thereby promote ratchet 9, drive the angle of moving contact 5 rotations that is contained in ratchet 9 rotating shafts 6 simultaneously and contact with a fixed contact 7.After solenoid 3 outages, armature 2 drives push rod 4 returns, ratchet 10 is retracted by return spring 12 is close to push rod 4, can not stir ratchet 9 toward revolution because of push rod 4 returns, ready for promote ratchet 9 next time, thereby realize that electric pulse of solenoid 3 every acquisitions just makes moving contact 5 rotate an angle, thereby realize the moving contact 5 of change over switch and the switching between each fixed contact 7.

Claims

1. solenoid tumbler, include solenoid and armature, it is characterized in that: be connected with a push rod on the described armature, on push rod, be hinged with ratchet, side at ratchet is equipped with ratchet, be connected with moving contact in the rotating shaft of this ratchet, on the movement locus of this moving contact, be provided with a plurality of fixed contacts.

2. solenoid tumbler according to claim 1 is characterized in that: be connected with return spring between described ratchet and described push rod.
