Problems solved by technology

[0009] A disadvantage of the prior art is that the damping of the yoke is based on an embedded rubber arranged between the yoke and the magnetic chamber floor, since the magnetic chamber floor is very inflexible and rigid and the thin embedded rubber associated with it cannot The shock absorption provided is very poor, so this shock still results in a strong rebound when the magnetic system is closed

Embodiment Construction

[0021] FIG. 1 shows a switching device 1 with a damping device 2 known from the prior art. The switching device 1 has a housing 3 which is composed of two parts, a housing lower part 4 and a housing upper part 5 . The housing lower part 4 is designed as a magnetic chamber 6 which has a magnetic chamber base 7 on its underside. The damping device 2 is arranged on the magnetic chamber floor 7 . Arranged in the magnetic chamber is a drive unit 8 comprising a yoke 9 placed on the magnetic chamber floor 7 , a coil 10 arranged above the yoke 9 and an armature 11 movably arranged above the coil 10 .

[0022] figure 2 shows an electromagnetic switching device 12 with a damping device 13 according to the invention. The switching device 12 has a switching area 14 which has a contact system and is arranged above an actuation area 15 . The drive region 15 includes a yoke 16 , a coil 17 arranged above the yoke 16 and an armature 19 arranged movably above the coil 17 . The coil 17 has ...

Abstract

The invention relates to a switching device (12), in particular a contactor, having a switching area (14) which has the contact system, and having a drive area (15) which comprises an armature (19), a coil (17) with a coil former (21), and a yoke (16). The invention is distinguished in that the yoke (16) is mounted elastically in the coil former (21) by means of a damping element (13a).

Description

technical field [0001] The invention relates to a switching device, in particular a contactor, having a switching region with a contact system and a drive region comprising an armature, a coil with a coil body, and a yoke. Background technique [0002] When the electromagnetic switching device is switched on, the impact of the magnetic armature with the magnetic core leads to undesired vibrations, which lead to so-called armature vibrations. In addition, the impact of the movable switching element with the stationary switching element produces contact oscillations, wherein the armature-core impact also counteracts the contact oscillations. [0003] Both of these effects are to be avoided as much as possible, because on the one hand, they shorten the service life of the magnetic system (especially the pole faces) and on the other hand, they generate vibration arcs on the contacts, which are harmful to the material. Losses are eliminated and the contacts are soldered in the w...
