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] in Figure 1 to Figure 4 An electromagnetically operated relay is shown in, where each contact can exist in pairs or separately. For example in figure 2 There are 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 manipulator 7 moves in the arrow direction 5 to its working position, and is pulled back to its rest position in the arrow direction 6 by the spring 3 engaged at its rear end.

[0076] The manipulator 7 is driven by the armature 2, the armature 2 is pivotally received in the pivot bearing 4 in the area of ​​the contact group carrier 1, and the armature 2 is driven by the drive coil 21 in the direction of the arrow 5.

[0077] In the illustrated embodiment, the manipulator 7 is composed of a flat insulating material and forms bumps 8, 10, 12, 14 arranged one after another. Here, grooves 9, 11 are respectively provided between the bumps. , 13.

Abstract

The present invention relates to an electromagnetic relay including at least one contact-set support (1) in which a plurality of contact springs (15-20) are fixed at the base end and, in pairs, form normally open and / or normally closed contacts (22-24), wherein at least one actuator (7) acts on a corresponding active contact spring (18-20). The actuator is movably driven in the longitudinal direction thereof by a magnet system (2, 3,4) and has actuating surfaces (26) for acting on the respective contact spring (15-17) to be actuated, wherein the transition that the contact springs (15-17) operates the actuator (7) from an upper first operation plane (25) to a lower second operation plane (27) is realized during the stroke of the actuator (7), the corresponding operation plane (26) correlated with the active contact spring (15-17) of the actuator (7) forms an angle relative to the operation direction of the actuator (7).

Description

Technical field [0001] The invention relates to a relay with an adjusted force-displacement characteristic curve as described in the preamble of claim 1. For example, this type of relay is proposed in the patent document EP 1121700 B2. The relay discloses adjusting the force-displacement characteristic curve according to the driving characteristic curve, so that the operator It can work on two different operating planes, that is, the operator for normally closed contacts is on a different horizontal plane than the operator for normally open contacts. In the manipulator conversion process, the normally open contact needs to be opened first before the normally open contact is closed without displacement (wegversetzen). This means that the force required to operate the normally open contact must be applied by the driver without delay. This realizes the adjustment of the force-displacement characteristic curve of the contact group. The advantage of this is that the drive charact...
