Definitions

the invention relates to a contact arrangement for relays with mutually opposite fixed and movable contact elements, two adjacent contact elements being able to be electrically conductively bridged by an opposing bridge contact element.
bridge contact arrangements have been known for a long time for shooters, but also for relays. They are used so that even large currents can be safely switched on and off at a given contact distance.
These known contact arrangements each have a movable bridge contact element which bridges the two opposite stationary contact elements, each provided with a connection.
the object of the invention is therefore to provide a contact arrangement which can switch large currents with a very small contact spacing or armature stroke.
this object is achieved in a contact arrangement of the type mentioned at the outset in that at least two fixed contact elements are opposed by at least two jointly operable movable contact elements, at least one of which is designed as a bridge contact element, and which are offset from one another in such a way that when actuated, the fixed ones and the movable contact elements are all switchable in series.
the contact arrangement not only is a movable bridge contact used, but in addition to the bridge contact, at least one further contact element which can be actuated together is arranged, which, in conjunction with at least one stationary bridge contact element opposite, results in a series connection of at least three contact distances. This results in the mode of operation of at least three times the contact spacing compared to a single contact.
the series connection of four or more contact spacings can also be achieved.
the fixed or movable contact elements which are arranged next to one another and which, if appropriate, are to be actuated together are expediently connected to one another in each case via an insulating material sheath.
One of these contact elements can be clamped as an elongated spring element in a relay housing, while the further contact element which can be actuated together with it is carried by it and is fastened to it via an insulating material sheath.
the connection can be made via a torsion bar, see above that a tolerance compensation and thus a perfect contact is achieved when switching.
FIG. 1 schematically shows a contact arrangement with a fixed contact bridge 1 and an individual contact element 2 arranged next to it, each of which has a movable contact bridge 3 offset and a movable individual contact element 4 arranged next to it.
the individual contact elements 2 and 4 are provided with connections, not shown.
the movable contact elements 3 and 4 are actuated together by a schematically shown actuator 5, whereby all four contact elements can be connected in series.
the contact distance a is switched three times in this way, so that there is the effect of a contact distance of (3 x a) between the terminal contact elements 2 and 4.
FIG. 2 A corresponding contact arrangement with an effective contact spacing of (4 xa) is shown in FIG. 2.
a further contact bridge 6 is arranged here, which is additionally opposed to the individual contact element 7.
the two contact bridges 3 and 6 are common actuated, which in turn all contact distances are switched in series.
FIG. 3 and 4 show in two views a specific embodiment for a combined contact element with a single contact and a bridge contact arranged next to it.
the contact element 9 is fastened at its end 9a in a manner not shown and carries a contact rivet 10 at its free end 9b.
This contact spring 9 carries an additional bridge contact element 12 via a narrow web 11, the two contact rivets 13 and 14 of which are aligned with the contact rivet 10 in FIG in a row.
the bridge contact element 12 is fastened to the torsion bar 11 by partial encapsulation with insulating material 15. When switching, this web 11 can be twisted to compensate so that perfect contacting of all three contact rivets 10, 13 and 14 is always achieved.
a bridge contact spring and a single contact spring could also be anchored separately next to one another in a spring clamping block.
FIG. 5 shows the application of the contact principle according to FIG. 1 to a changeover contact in a relay.
the relay housing 21 contains a conventional magnet system 22 with an armature 23, which is only hinted at.
This armature actuates a central contact spring arrangement, consisting of a single contact element 24 and a bridge contact element 25, which can be switched between two fixed contact element pairs.
These fixed contact elements exist on the Rest side of a bridge contact element 26 and a single contact element 27 and on the working side of a single contact element 28 and a bridge contact element 29.
the fixed contact elements 27 and 28, as well as the movable contact element 24 are each provided with a connection.
the bridge contact elements 26 and 29 are pressed into the guide grooves 30 and 31 of the coil body flange 32 in a clawed manner.
the movable contact elements 24 and 25 are actuated together, so that here again the contact distance is switched three times in succession, whereby the switching capacity of the relay compared to a single contact as well as compared to a conventional bridge contact can be increased significantly.
the contact spacings can therefore be connected several times in succession without connections having to be led out from each contact element and connected in series in terms of circuitry.
