Abstract
The present invention relates to a kind of switching device (12), especially catalyst, have: switch region (14), this switch region has contact system；With drive area (15), this drive area includes armature (19), with the coil (17) of coil case (21) and yoke (16).It is a feature of the present invention that yoke (16) is flexibly placed in described coil case (21) by damper element (13a).
Description
Technical field
The present invention relates to a kind of switching device, especially catalyst, have: switch region, this switch
Region has contact system；And drive area, this drive area includes armature, line with coil case
Circle and yoke.
Background technology
When connecting electromagentic switching apparatus, magnetic armature result in unexpected vibration with the shock of magnetic core,
This unexpected vibration causes so-called armature chatter.It addition, movable switch element is with fixing
The shock of switch element create contact chatter, wherein, contact is also shaken by the shock of armature-iron core
Move and create retroaction.
Both effects are all intended to do one's utmost to avoid, because on the one hand both effects shorten magnetic system
Service life and the another aspect of (especially pole-face) create oscillating arc on contact, and this shakes
Galvanic electricity arc creates loss and is welded contact in the most adverse case material.
Repeatedly lifting of contact may cause uncontrollable equipment to control error.It addition, vibration is the most right
The stability of electrical connection, fixing and parts the service life of switching device cause adverse effect.
Switching device with AC-driver element has the highest connection speed when closed magnetic system
Degree.Here, the armature with contact holder strikes in yoke, and movable contact carriage is from disconnected
Open position strikes in the fixed contact on on-position.Based on high stroke speed, armature can be with
Contact holder and its movable contact carriage are clashed into again and are returned on open position, and this is thus referred to as
So-called contact bounce.
Thus, creating electric arc between movable contact and fixing contact, this electric arc is to switch
The service life with electricity of the machinery of device creates harmful effect.
A kind of magnetic damping device, wherein, the yoke quilt in housing is there is known by EP 0 855 084 B1
On the strip rubber absorbers along yoke longitudinal extension being held in place on Housing Base and
Being disposed with the cushioning pressure spring of taper between coil case and yoke, this cushioning pressure spring is towards housing
The direction extruding yoke of base plate and when magnetic system closes spring force by cushioning pressure spring subtract
The weak armature shock to yoke.
Be there is known a kind of magnetic damping device by EP 0 855 085 B1, wherein, Housing Base is designed to
It is vibratile, here, yoke is positioned in below the intermediate layer embedding rubber and magnetic room base plate sets
Meter has two different elastic bearing regions, and the elasticity in one of them region is more weak and another district
The elasticity in territory is the strongest.According to the make of the support strip in the base plate of magnetic room, spring effect is permissible
It is matched with required damping.
The defect of prior art is, the damping of yoke is based on being arranged between yoke and magnetic room base plate
Embed rubber, be the most inflexible due to magnetic room base plate and be hard and relative thin
To embed the damping effect that can be provided by of rubber excessively poor, so this damping is still when magnetic system closes
Strong resilience can be caused.
Summary of the invention
Thus, it is an object of the invention to realize a kind of switching device with damping device, this damping
Device can when magnetic system closes decreasing rebound significantly.
This purpose is realized by the switching device of the present invention.
Switching device according to the present invention, especially catalyst, have: switch region, and it has and connects
The system of touching；And drive area, it includes armature, with the coil of coil case and yoke.The present invention
Being characterised by, yoke is flexibly placed in coil case by damper element.It is designed as, coil case
Surround this damper element completely.This damper element is preferably made up of rubber.
Being designed as in another advantageous embodiment, coil case itself is the most flexibly placed in magnetic room
In, thereby producing two parts damping, this is, is on the one hand that yoke is flexibly placed in coil case
In, and be on the other hand that coil case itself the most flexibly disposes.Preferably, coil case is by spring
Flexibly it is placed in magnetic room.It is designed as in a special embodiment according to the present invention, passes through
It is used as the plastic arm flexibly positioned coil body of spring element.
Damping device according to the present invention is characterised by, yoke is flexibly placed in by damper element
In coil case and coil case surrounds this damper element completely.Furthermore it is possible to the most flexibly dispose
Whole coil case, therefore this damping device is divided into two damping devices.
