Abstract
The electrical switch includes the slide (44) which is mounted parallel to the principal surfaces of the casing and perpendicular to the rear surface by which it is fixed. It runs against a guide surface, channelled by a pair of strips on the slide which extend parallel to the direction of displacement. The shoulder (45A) lies parallel to the displacement direction and butts against the guide at the rear. The cam mechanism is between the contact support (12) and the slide. An edge (62) on the support corresponds with a slope (63) on the slide so as to impede the path of the edge from the open to closed position of the contacts along an oblique direction relative to the slide direction.
Description
Technical field:
The present invention relates generally to electric equipment, wherein in its machine box, include a contact supporting, a moving contact is installed on it at least versatilely, the latter decides contact with respect to one at least and carries out general layout, and installs versatilely between itself enable possition in above-mentioned machine box and the off-position.When the enable possition, above-mentioned moving contact with decide contact and be spaced a distance, and when off-position, above-mentioned moving contact then is close to this and is decided on the contact.And flexible device and this moving contact are combined, and it leans against on the contact supporting, and impel this moving contact always towards a thrust block of preparing for its on contact supporting.
Background technology: it refers more particularly to, though not unique, a such situation, promptly this electric equipment is a differential type switch, for example, resemble on January 17th, 1992 application, its application number be No. 9200452 and with the french patent document of No. 2686453 bulletins described like that.
When closing, this moving contact under the stress of its contact supporting of supporting, applies contact pressure to deciding contact, owing to the increase gradually of bearing the elastic device elastic force of this power contact pressure being increased gradually, till the penetration power that provides whole hope to obtain with it.Yet above-mentioned contact pressure is zero at first.
In other words, the locking process on the off-position of electric equipment is little by little to take place.
The arrangement of said apparatus still can be satisfactory, especially for the more moderate electric equipment of its rated value.
But for the bigger electric equipment of its rated value, or rather, its rated value is greater than the electric equipment of 40A, sometimes then find, under same size of current, deciding between contact and the moving contact, do not form a kind of row pressure power in good time, its intensity constantly increases, and causes the upset to this closed condition easily.
Similarly, find also that sometimes in this case, this moving contact will be the object that sticks on the fixed contact subsequently.
In french patent document FR 2717617, describe one and be contained in the mechanism that blocks that the activity between expanded position and punctured position is installed in this machine box.When expanded position, the stroke of moving contact is intervened by a convex shoulder, therefore is suitable for temporarily blocking it.On punctured position, it is to be suitable for discharging above-mentioned moving contact.In addition, this blocks mechanism and also makes up flexible device on the one hand, and it impels the former always towards its expanded position.Cam gear blocks between the mechanism at contact supporting and this and works on the other hand, thereby cause when its process be when changing to the process of off-position from the enable possition, above-mentioned contact supporting itself impels above-mentioned mechanism changes to punctured position from expanded position the process of blocking.
Therefore, when closing because the compression that increases progressively of the elastic device combined with it, the temporary transient barred of this moving contact, and with decide contact every a segment distance.
Therefore, moving contact is becoming big contact pressure, decides on the contact but not act on when discharging subsequently by zero contact pressure.
In other words, so implement because block mechanism, so the locking process of electric equipment is just carried out in unexpected mode.
In this case, might avoid moving contact and decide the adhesion of contact, even also be like this for the bigger electric equipment of rated value.
Yet in french patent document FR 2717617, this blocks mechanism is that rotation is installed in the machine box.
In addition, it acts in a zone on this moving contact, and this zone is in a side of moving contact.And by opposite side, moving contact is suitable for being placed on the fixed contact, and this zone need be away from the opposite side of contact.
In this case, before release, be difficult to control moving contact accurately and efficiently with respect to the stop position of deciding contact.
Summary of the invention: the present invention aims to provide a kind of setting, and it has been avoided above-mentioned shortcoming simply and has brought other advantages.
Or rather, content of the present invention is a kind of electric equipment, a contact supporting is arranged in its machine box, moving contact of movable at least installation on this support, the latter decides contact with respect to one at least and carries out integral installation, and installs versatilely between itself enable possition in the machine box and the off-position.When the enable possition, this moving contact with decide the contact segment distance of being separated by; When off-position, this moving contact is close to and is above-mentionedly decided on the contact.And flexible device and moving contact are combined, and it leans against on the contact supporting, and impel this moving contact always towards a thrust block of preparing for its on contact supporting.In addition, also settled one versatilely and block mechanism in its machine box, the latter is placed between expanded position and the punctured position.When expanded position, the stroke of moving contact is intervened by a convex shoulder, therefore is suitable for temporarily blocking it.When punctured position, it is to be suitable for discharging above-mentioned moving contact.In addition, this blocks also combined elastic device of mechanism on the one hand, and it impels the former always towards its expanded position.On the other hand, cam gear blocks between the mechanism at contact supporting and this and has an effect, thus cause when its when the enable possition changes to off-position, above-mentioned contact supporting itself just impels this to block mechanism to change to punctured position from expanded position.One of feature of this electric equipment is that the above-mentioned mechanism that blocks is a slide block.
Except having easy structure, above-mentioned setting can also make and block mechanism's domination moving contact, and is suitable for being placed in the zone of deciding contact.In this case, before release,, can very accurately control the temporary transient stop position of moving contact with respect to deciding contact.
In addition, this blocks mechanism and can not have an effect to other mechanism units of electric equipment.When this electric equipment is installed, whether it can be installed as required, can also increase or not increase parts simply.
