Description
Technical field
The utility model relates to a kind of relay switch, and a kind of low-voltage controls the electromagnetic relay of high voltage break-make specifically.
Background technology
Electromagnetic relay is a kind of electronic control device, and it has control system and by control system, is usually applied in automatic control circuit, and it is actually a kind of automatic switch removing to control larger current and higher voltage with less electric current and lower voltage.Electromagnetic relay is generally made up of electromagnet, armature, spring leaf, contact etc., and its operating circuit is made up of low-voltage control circuit and high-pressure work circuit two parts.As long as add certain voltage at coil two ends, certain electric current will be flow through in coil, thus generation galvanomagnetic effect, the pulling force that armature will overcome return spring under the effect of electromagnetic attracting force is inhaled to dynamic iron core, thus the moving contact of band moving armature and fixed contact adhesive.When after coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return to original position at the reaction force of spring, and moving contact and original fixed contact are discharged.Such adhesive, release, thus the object reaching conducting in circuit, cut-out.Patent Office of the People's Republic of China is disclosed in 12 days September in 2012, the patent No. is " a kind of electromagnetic relay with double-contact " of " 201220022843.8 ", it comprises insulator foot, coil is equipped with on the top of insulator foot, coil comprises winding, two leading foots of winding are inserted on insulator foot, insulator foot is also inserted with common port pin and normal beginning pin, armature is equipped with in the front end of winding, a movable contact spring is fixed in one end of armature, the common port pin and the normal beginning pin that are in insulator foot top are respectively provided with a contact, movable contact spring is provided with the contact of two mutual conduction, two contacts on movable contact spring are corresponding with the contact on described common port pin and normal beginning pin respectively, when movement under the effect of armature at winding can drive on movable contact spring two contacts to contact with the contact on described common port pin and normal beginning pin simultaneously.This electromagnetic relay volume or excessive, is difficult to be applied to more occasions.
Summary of the invention
The purpose of this utility model is defect for above-mentioned prior art and deficiency, and for people provide a kind of structure simple, the electromagnetic relay of compact, controls the break-make of high voltage.
Technical solution adopted in the utility model is for achieving the above object: this electromagnetic relay comprises the insulation shell and insulating base that mutually fasten, two low tension terminals and two high tension terminals are fitted with above insulation shell, in insulation shell, coil is installed, the central movable of coil is interspersed with dynamic iron core, two exits of coil are connected with corresponding low tension terminal respectively, the top of described coil and dynamic iron core is covered and fixed cover is housed, this fixed cover has magnetic conductivity, the top of dynamic iron core is fixed with push rod, the upper end of push rod is through fixed cover, and in the upper end of push rod, movable contact spring is installed, two terminal contacts of movable contact spring lay respectively at below corresponding high tension terminal, contact when dynamic iron core moves on movable contact spring and high tension terminal offset, Compress Spring is supported with between described push rod and insulation shell.
Two terminal contacts of described movable contact spring are upturned.
Described coil bottom is provided with supporting bracket, and the below of supporting bracket is provided with packing ring.
Described push rod upper end is provided with spring fixed frame, and the bottom of Compress Spring embeds in spring fixed frame.
The exit of described coil and the bottom welding of low tension terminal.
The two ends of described insulating base are provided with mount pad.
As long as the utility model connects low tension terminal, just coil electricity can be made, iron core is made to have magnetic by electromagnetic induction, because the fixed cover above dynamic iron core has magnetic conductivity, therefore dynamic iron core moves and fixed cover adhesive, contact now on movable contact spring and high tension terminal offset, and make two high tension terminal conductings.During low tension terminal power-off, dynamic iron core falls down, high tension terminal disconnects.The utility model eliminates quiet dynamic iron core, makes volume more small and exquisite, has the advantage that structure is simple, be convenient to installation, is applicable to the break-make that more occasions control high voltage.

Embodiment
As shown in Figure 1, Figure 2, Fig. 3 shows, the utility model is a kind of electromagnetic relay, and it comprises the insulation shell 5 and insulating base 2 that mutually fasten, is fitted with two low tension terminals 1 and two high tension terminals 4 above insulation shell 5.The two ends of described insulating base 2 are provided with mount pad 3, are convenient to install.In insulation shell 5, be provided with coil 12, the central movable of coil 12 is interspersed with dynamic iron core 10, and two exits of coil 12 are connected with corresponding low tension terminal 1 respectively.As long as connect low tension terminal 1, coil 12 just can be made to be energized, to make iron core 10 have magnetic by electromagnetic induction.The exit of described coil 12 and the bottom welding of low tension terminal 1, make connection more reliable.Be provided with supporting bracket 13 bottom described coil 12, for support coils 12, the below of supporting bracket 13 is provided with packing ring 14.The top of described coil 12 and dynamic iron core 10 is covered and fixed cover 11 is housed, and this fixed cover 11 has magnetic conductivity, therefore when dynamic iron core 10 has magnetic, dynamic iron core 10 can move up and with fixed cover 11 adhesive.The top of dynamic iron core 10 is fixed with push rod 9, and the upper end of push rod 9 through fixed cover 11, and is provided with movable contact spring 8 in the upper end of push rod 9, and two terminal contacts of movable contact spring 8 lay respectively at below corresponding high tension terminal 4.When dynamic iron core 10 moves, the contact on movable contact spring 8 and high tension terminal 4 offset.Two terminal contacts of described movable contact spring 8 are upturned, and make compressing of contact and high tension terminal 4 more reliable.Be supported with Compress Spring 6 between described push rod 9 and insulation shell 5, when dynamic iron core 10 loses magnetism, the gravity of the restoring force of Compress Spring 6 and dynamic iron core 10 self makes iron core 10 fall after rise fast, makes two high tension terminals 4 disconnect from face.Described push rod 9 upper end is provided with spring fixed frame 7, and the bottom of Compress Spring 6 embeds in spring fixed frame 7, prevents Compress Spring 6 from skidding off.
