Abstract
The present invention includes casing, contact, winding and contact moving mechanism comprising permanent magnet, iron bar and frame. When direct current flows through the winding in right or reverse direction, the iron bar produces magnetic field in opposite directions, and the attraction and the repellence produced between the magnetic field of iron bar and that of permanent magnet is utilized to control contactor or relay. After the contactor or relay actuates, the iron bar is attracted firmly by the permanent magnet, the winding needs no further current.
Description
The present invention relates to a kind of electromagnetic contactor or relay, belong to the electric controling element technical field.
Electromagnetic contactor or the relay that uses is made up of shell, support, iron-core coil, armature, contact and actuating mechanism thereof at present, they are all by making contactor or relay work for coil electricity, when coil gets when electric, its armature is attracted by iron core and drives the contact action.Contactor or relay in the course of the work, its coil must keep "on" position, has so both wasted electric energy, produces noise again.
In view of above-mentioned, purpose of the present invention just provides a kind of energy-saving no-noise contactor/relay that overcomes above-mentioned defective.
For achieving the above object, the present invention adopts following design:
A kind of permanent-magnet electromagnetic contactor/relay, comprise shell frame, coil, contact and actuating mechanism thereof, it is characterized in that: described contact actuating mechanism is made of support, iron staff, permanent magnet, wherein: coil is enclosed within on the iron staff, iron staff is bearing on the support, and permanent magnet is fixed on the position of corresponding iron staff termination on the support.
Described permanent magnet is separately fixed at the position of two terminations of corresponding iron staff on the last lower cross frame of support.
Described support is divided into up and down two parts, and described iron staff is fixed on the lower cross frame of support, and described permanent magnet is fixed on the position of corresponding iron staff termination on the last crossbearer of support, between last crossbearer and the described shell frame back-moving spring is set.
The present invention utilizes to coil and passes to forward and reverse direct current, produces the magnetic field of two kinds of different directions on iron staff, utilizes the principle that the same sex is repelled each other between iron staff magnetic field and permanent magnet, there is a natural attraction between the sexes to come the control contactor or the actuating of relay again.After the contactor or the actuating of relay, owing to iron staff is firmly held by permanent magnet, so need not continue to coil electricity.
The present invention is owing to adopting said structure, so have the following advantages:
1. energy-conservation.The present invention only need pass to electric current in moment closed or that disconnect, and normal operating conditions does not need energising, and therefore the contactor or the relay of comparable present use are saved a large amount of electric energy.
2. noiselessness during operate as normal.The present invention thereby can not produce noise owing to need not energising when operate as normal.
3. has explosion prevention function.No current when working because of the present invention does not produce heat, need not consider heat dissipation problem during manufacturing, and contactor or the relay of therefore making explosion-proof type are just very simple.
4. manufacturing process is simple.Make the present invention and need not to use silicon steel sheet, as long as common soft iron rod.
Below in conjunction with drawings and Examples the present invention is elaborated.
Fig. 1 is a structural representation of the present invention;
Fig. 2 and Fig. 3 are respectively two application examples.
See also accompanying drawing 1: the present invention includes shell frame, contact (all not illustrating in the drawings), contact actuating mechanism, coil 5, the contact actuating mechanism is made up of permanent magnet 1 and 2, iron staff 3, support 4.Wherein: coil 5 is enclosed within on the iron staff 3, and iron staff 3 is bearing on the support 4, and permanent magnet 1 and 2 is fixed on the position of corresponding iron staff 3 terminations on the support 4.Among the figure, two blocks of permanent magnets 1 and 2 are separately fixed at the position of two terminations of corresponding iron staff 3 on the support 4.
The present invention has multiple embodiments, only lifts two example explanations below.
See also Fig. 2, iron staff 3 is bearing between the last lower cross frame of support 4, and two blocks of permanent magnets are separately fixed at the position of two terminations of corresponding iron staff 3 on the last lower cross frame of support, and the contact is promoted by iron staff 3.
As the E that closes a switch, cut-off switch F, when passing to the direct current of forward for coil 5, iron staff 3 is magnetized, and repels each other with permanent magnet 2 and inhales mutually with permanent magnet 1, so iron staff 3 moves and firmly held by permanent magnet 1 towards permanent magnet 1 direction.Iron staff 3 promotes the contact action therebetween, reaches the function of common contactor or relay power, and this is contactor or relay attracting state.Because this moment, iron staff 3 was firmly held by permanent magnet 1, so need not continue to coil electricity.Iron staff 3 action back contact M disconnect and contact K connection, and coil cuts off the power supply automatically.
As the F that closes a switch, cut-off switch F, when passing to reverse direct current to coil, iron staff 3 is magnetized, and repels each other with permanent magnet 1 and inhales mutually with permanent magnet 2, so iron staff 3 firmly holds towards the motion of permanent magnet 2 directions and by permanent magnet 2.Iron staff 3 releasing contacts reach the function that the outage of common contactor or relay discharges therebetween, and this is contactor or relay release condition.Because this moment, iron staff 3 was firmly held by permanent magnet 2, so need not continue to coil electricity.Iron staff 3 action back contact K disconnect and contact M connection, and coil cuts off the power supply automatically.
The present invention can be with two blocks of permanent magnets, also can be only with a permanent magnet, replace another piece permanent magnet with back-moving spring again, promptly as shown in Figure 3, support 4 is divided into two parts up and down, iron staff 3 is fixed on the lower cross frame of support 4, and permanent magnet 1 is fixed on the position of corresponding iron staff termination on the last crossbearer of support 4, between last crossbearer and the shell frame 6 back-moving spring 7 is set.The contact is promoted by last crossbearer.
When passing to DC Forward Current for coil 5, iron staff magnetic field makes permanent magnet 1 overcome the elastic force of back-moving spring 7 and inhales tightly mutually with iron staff 3, owing to iron staff is inhaled mutually with permanent magnet, so behind the coil blackout, contactor or relay still keep attracting state.And when passing to reverse dc,, make permanent magnet move upward, and keep by the pulling force of back-moving spring towards the direction that deviates from iron staff because the magnetization iron staff and the permanent magnet same sex are repelled each other to coil.Behind the coil blackout, contactor or relay still keep release condition.
The material of above-mentioned iron staff is a soft iron, and this iron staff can be made with other soft magnetic material.
From as can be known above-mentioned, the present invention utilizes the mutual motion between iron staff and the permanent magnet to promote the contact action, and connected mode by last crossbearer and contact of the connected mode of above-mentioned iron staff and contact, permanent magnet, and the supporting structure of iron staff and support all belong to known technology, repeat no more herein.
Below only be part embodiment of the present invention, any based on equivalents of the present invention, all should be within protection scope of the present invention.
