Definitions
- the present invention relates to an electromagnetic relay according to the preamble of claim 1 and to a method for producing the same.
- KL-armature relays Relays with an armature, which is stored in a cutting edge bearing, are known in particular as so-called KL-armature relays.
- a retaining spring is provided which pulls the armature with a notch against an edge of the magnetic yoke.
- holding springs both those made of metal strips or spiral springs are known, for example from CH-PS 20 68 32 or DE-AS 20 29 607.
- DE-PS 30 08 783 are plastic holding springs, for example molded onto the coil body. All of these designs have in common that the bearing and restoring force generated by the holding springs and acting on the armature depends on the spring force thereof. In mass production, however, a desired spring characteristic can only be produced within certain tolerance limits.
- the present invention is therefore intended to achieve the object of specifying a possibility with which it is possible to precisely define the restoring force and thus the contact pressure of a normally closed contact without great effort and with very low tolerances.
- a relay according to the invention is shown schematically in the drawing.
- a coil body 2 is fastened, which carries an excitation coil 3 and is penetrated by a core 4.
- an edge 6 is formed as a bearing cutting edge, which together with a notch 7 of an anchor 8 designed as a cap anchor forms a cutting edge bearing.
- a leaf spring 11 serving as a power supply to a slide contact 9, 10 is fastened.
- the leaf spring 11 is designed as an angle and has a free protruding angle arm 12. The latter is arranged in a direction which is at least approximately in the direction of a spring force generated by a retaining spring 13.
- the holding spring 13 is designed as an angled spring clamped on one side and the free leg 14 lies against the angled arm 12 and is firmly connected to it, for example by welding or soldering. Both therefore form an overlapping connecting piece 15.
- the clamped leg 16 of the retaining spring 13 pulls the free leg 14 downward and exerts a restoring force on the armature 8 via the angle arm 12, ie it pulls and presses it with its notch 7 against the Bearing edge 6 that he is in the lifted, so. Quiet position, is pulled.
- the normally closed contacts 9, 10 lie on one another with a contact pressure which depends on the return spring force of the holding spring 13.
- the connection of the free angle arm 12 to the free leg 14 of the retaining spring 13 is made only after these parts have been installed and the restoring force has been set in the process. This is done in such a way that a defined, pressure Y corresponding to the desired restoring force.
- the armature 8 is in one end position, in particular in the rest position, and the normally closed contacts 9, 10 are closed. In this position, the overlapping parts of the retaining spring 13 and the leaf spring 11 are connected to one another.
- the retaining spring 13 then exerts a restoring force on the armature 8, which is transmitted in relation to the distance 17 of the connecting piece 15 from the cutting edge bearing 6, 7 to the distance 18 of the normally closed contact 9, 10 from the cutting edge bearing 6, 7 to the normally closed contact 9, 10.
- the contact pressure X can be set precisely in a simple manner, depending on the spring characteristic of the retaining spring 13. It is therefore also possible to produce 13 different types of relays with different break contact faults, i.e. also for different currents and voltages, with one holding spring.
