Push button element and sliding element of adjustment device and adjustment device and method for adjusting the position of a thermally actuated shaft

Abstract

The invention relates to a button element and a slide element of an adjusting device, an adjusting device and a method for adjusting the position of a thermally actuating shaft, as well as a thermomagnetic actuating unit and a current for interrupting an electrical switching circuit in the event of a triggering event An electrical switch for a flow of current having said adjusting device having a push button element supported in a rotatable manner and a sliding element supported in a tangentially movable manner, wherein the The push button element and the slide element are operatively connected such that a rotational movement of the push button element is converted into a tangential movement of the slide element.

Description

technical field [0001] The present invention relates to a button element and a sliding element of an adjustment device, and to an adjustment device and a method for adjusting the position of a thermal trigger shaft of a thermal trigger device of an electric switch. Furthermore, the invention relates to a thermomagnetic triggering unit of an electrical switch and to said electrical switch, and in particular to a compact power switch for interrupting the current flow of a current of an electrical switching circuit in the event of a triggering event . Background technique [0002] Basically know, for example, design compact power switches (MCCB=Molded Case Circuit Breaker) based on the principle of magnetic mutual repulsion or interruption or separation of contacts. In this case, the contacts open before the approximately possible peak value of the short-circuit current is reached. Due to the opening of the contacts, the thermal and mechanical stresses of the system component...

Problems solved by technology

However, such play disadvantageously leads to an imprecise positioning of the individual components and in particular of the triggering axes relative to one another and also to the remaining components of the thermomagnetic triggering unit, which in turn may lead to Inaccurate adjustment or adjustment of the thermomagnetic trigger unit and in particular of the trigger axis of the thermomagnetic trigger unit

In addition, the known embodiment of the adjusting button is realized by means of a pin which is inserted into the insertion area of ​​the trigger shaft and in particular of the thermal shaft, which furthermore has no rotational movement of the adjusting button. Problems converting linearly to tangential or axial movement of the trigger shaft

The known adjusting mechanism has a scale of rotation angle of a maximum of 180°, wherein a linear scale along the axis of rotation of the adjusting knob cannot be realized, especially because of the distance between the adjusting knob and the triggering axis. The axial movement of the trigger shaft in the range of 0° or 180° of the rotary movement of the adjusting button is very small compared to the axial movement in the range of 90° of the
