Problems solved by technology

[0005] First of all, it should be avoided that the characteristic curve of the contact group intersects the drive characteristic curve of the magnet system, because this would result in an unstable operating stroke and no longer ensure a rapid, smooth and continuous operation of the contact group

Embodiment Construction

[0075] exist Figure 1 to Figure 4 An electromagnetically operated relay is shown in , wherein the individual contacts can be present in pairs or individually. For example in figure 2 There is a normally open contact 22, another normally open contact 23 and a normally closed contact 24, all of which are jointly operated by the operator 7. The operator 7 is moved in the direction of the arrow 5 into its working position and is drawn back in the direction of the arrow 6 into its rest position by the spring 3 engaged at its rear end.

[0076] The drive of the operator 7 takes place via the armature 2 , which is pivotally housed in a pivot bearing 4 in the region of the contact group carrier 1 , and which is driven by a drive coil 21 in the direction of the arrow 5 .

[0077] In the exemplary embodiment shown, the actuator 7 consists of flat insulating material and forms successively arranged projections 8 , 10 , 12 , 14 , between which grooves 9 , 11 are respectively provided ...

Abstract

The invention relates to an electromagnetic relay having at least one contact group carrier (1) in which a plurality of contact springs (15-20) are clamped on the base side and each paired Form normally open and normally closed contacts (22-24), wherein at least one operator (7) acts on the corresponding active contact spring (18-20), which operator can be passed through the magnet system (2, 3, 4) is movably driven along its longitudinal extension direction and has an operating surface (26) for acting on the corresponding contact spring (15-17) to be operated, wherein the operator (7) The transition of the operation of the contact spring (15-17) operated by the operator (7) from the upper first operating plane (25) to the lower second operating plane (27) is realized during the stroke, wherein the operator The corresponding operating face ( 26 ) of ( 7 ) associated with the active contact spring ( 15 - 17 ) forms an angle ( 36 ) with respect to the operating direction of the operator ( 7 ).

Description

technical field [0001] The invention relates to a relay with an adjusted force-displacement characteristic curve according to the preamble of claim 1 . A relay of this type is proposed, for example, in patent document EP1121700B2. The relay discloses the adjustment of the force-displacement characteristic curve according to the driving characteristic curve, so that the operator It is possible to work on two different operating planes, that is, the operator for the normally closed contacts is on a different horizontal plane than the operator for the normally open contacts. During the switchover of the operator, the normally closed contact first needs to be opened before the normally open contact closes without displacement (wegversetzen). This means that the force required to actuate the normally open contact must be applied by the drive without delay. This enables an adjustment of the force-displacement characteristic curve of the contact group. This has the advantage tha...
