Abstract
The utility model discloses a DC contactor improved structure which comprises a base and comprises a magnetic steel and two static contacts arranged on the base. An angle is formed between the connection line of the two static contacts and a magnetic induction line generated in the connection and disconnection of the two static contacts. According to the DC contactor improved structure, through improving the position distribution of the DC contactor contacts and a magnetic field, the angle is formed between the magnetic induction line and the connection line of the two static contacts, in this way, when a DC contactor is in reverse connection and disconnection working states, although two side electric arcs are pulled toward the inner side, an intersection part is greatly reduced, and so the electric arc is easier to be quickly extinguished compared with a traditional DC contactor. At the same time, ceramic insulation is added between the two static contacts, and the insulation distance between the two static contacts is effectively increased.
Description
Technical field
The utility model relates to a kind ofly can control interrupted electronic component automatically, relates in particular to a kind of D.C. contactor structure-improved.
Background technology
At present, the D.C. contactor on market generally adopts magnetic field to extinguish the electric arc producing when cut-off sound contact, reaches the object of thorough disconnecting consumers.Its operation principle is: utilize magnetic field that sound contact is disconnected to the electric arc producing and elongate, and then disconnect.But its must by the electric arc of fixed contact both sides all outwardly layback open, otherwise the electric arc of both sides crosses, and cannot reach the object thoroughly disconnecting fast.Meanwhile, because magnetic field has directivity, under definite magnetic field, in order to reach above-mentioned arc quenching effect, D.C. contactor needs to distinguish both positive and negative polarity in use.But under the service condition of current D.C. contactor, need product to there is certain reverse make-break capacity, and the reverse make-break capacity of traditional D.C. contactor is very poor.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of D.C. contactor structure-improved, by improving the position distribution in D.C. contactor contact and magnetic field, makes the reverse make-break capacity of D.C. contactor improve approximately 4 times, and can realize the effect of fast arc extinction.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of D.C. contactor structure-improved, comprise base and be located at magnet steel and two fixed contacts on this base, between the line of magnetic induction producing when the line of described two fixed contacts and this two fixed contacts break-make, thering is angle.
As further improvement of the utility model, described angle is acute angle.
As further improvement of the utility model, described angle is 45 °.
As further improvement of the utility model, described two fixed contacts are provided with insulating ceramics in the space between described base inner side.
The beneficial effects of the utility model are: this D.C. contactor structure-improved, by improving the position distribution in D.C. contactor contact and magnetic field, make the line of the line of magnetic induction and two fixed contacts at an angle, like this at D.C. contactor during in reverse break-make operating state, although both sides electric arc pulls open towards inner side, but the part that crosses greatly reduces, and the more traditional D.C. contactor of electric arc is more easily extinguished fast.Meanwhile, between two fixed contacts, increase ceramic insulation, effectively increased the insulation distance between two fixed contacts.
Accompanying drawing explanation
Fig. 1 is the utility model Facad structure schematic diagram;
Fig. 2 is the utility model cross-sectional view;
Fig. 3 is that the utility model forward uses view;
Fig. 4 is that the utility model oppositely uses view.
By reference to the accompanying drawings, make the following instructions:
1---base 2---magnet steel
3---fixed contact 4---insulating ceramics
Embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection range of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
As shown in Figure 1, 2, a kind of D.C. contactor structure-improved, comprises base 1 and is located at magnet steel 2 and two fixed contacts 3 on this base.Wherein, between the line of magnetic induction producing, have angle when the line of two fixed contacts 3 and this two fixed contacts break-make, this angle is preferably acute angle, is particularly preferably 45 degree.This D.C. contactor is in the time of normal use, and as shown in Figure 3, the electric arc at two fixed contact places all pulls open toward the outer side; While oppositely use, as shown in Figure 4, the electric arc of both sides all inwards pulls open, and partly greatly reduces but cross, and the more traditional D.C. contactor of electric arc is more easily extinguished, thereby reach the object of fast shut-off.
In this D.C. contactor structure-improved, in the space at two fixed contacts between base inner side, also fill and be provided with insulating ceramics 4, can effectively increase the insulation distance between two fixed contacts.
Claims (4)
1. a D.C. contactor structure-improved, comprise base (1) and be located at magnet steel (2) and two fixed contacts (3) on this base, it is characterized in that: between the line of magnetic induction producing when the line of described two fixed contacts and this two fixed contacts break-make, there is angle.
2. D.C. contactor structure-improved according to claim 1, is characterized in that: described angle is acute angle.
3. D.C. contactor structure-improved according to claim 2, is characterized in that: described angle is 45 °.
4. according to the D.C. contactor structure-improved described in any one in claims 1 to 3, it is characterized in that: described two fixed contacts are provided with insulating ceramics (4) in the space between described base inner side.
