Definitions
- the invention relates to an electromagnetic switching device with a magnetic core and an anchor connected to a receiving part.
- the invention is based on the object, as versatile as possible attachment for the anchor to create, with constant given mechanical forces to reduce the overall height of the anchor is around the To be able to use anchors in different shooters.
- This object is according to a connected to a receiving part anchor according to the invention achieved in that the armature at two opposite Side lateral hook-shaped projections under training a magnetic core facing Ein goodnut and at least a bracket on each of the two opposite sides of the hook-shaped projection encompassing with a bent hooking end is suspended in the Ein healthynut, so that the anchor to at least two each other opposite arranged ironing is suspended and on the Magnet core remote from the top of the armature arranged the receiving part is and the bracket with its other bent attachment end the receiving part overlap and by means of a screw of the bracket on the receiving part is fastened.
- the inventively proposed anchor attachment by means of individual Bracket wherein at least one pair of brackets is provided for an anchor takes place exclusively on the sides of the anchor.
- This will cause a cross-sectional loss avoided by a central attachment by means of pins, as in the anchor center is no hole and thus the overall height of the anchor can be reduced be given excitation without loss of power of the drive against an anchor attachment according to the prior art.
- the temples allow a very simple attachment of the anchor to the receiving part by means Screws, wherein the receiving part applied to the top of the anchor is and clasp the temples anchor and receiving part laterally. That's already given a simple positive engagement and the subsequent attachment means Screw connection leads to a nearly rigid connection between receiving part and anchor.
- Another embodiment of the anchor attachment according to the invention is therein to see that the bracket C-shaped with a short bent hooking end and a long approximately at right angles rounded bent attachment end are formed. By forming a rounded bent long leg, a bias of the bracket is generated, which is favorable for the assembly and the anchor clearly positioned.
- higher power requirements in the device can be the bias of the hanger or the number of hangers, with where the anchor is attached to the receiving part can be increased.
- Two brackets can be four straps for attaching the anchor to the receiving part be provided, for example, very high for switching devices Performance, such as vacuum switching devices.
- the receiving parts to which the anchor is attached by means of the bracket are on its top for attachment of the bracket with appropriate mounting areas or investment areas for the temple ends and trained have a corresponding screw hole for the mounting screw for the respective bracket on.
- a connection between the armature and receiving part by means of Bar reached which corresponds to a rigid connection.
- the armature 1 according to FIGS. 1 and 2 can be made in one piece or from one by means of rivets 12, 13 held together laminated core, the laminated cores Through holes 12a, 13b have and outer cover plates 11 are covered.
- the anchor is laterally with hook-shaped projections 121 formed to the lower edge 14, i. the magnetic core facing side, limit the Ein fatiguenut 122 to the armature core out.
- the hook-shaped projections 121 ends at a distance s in front of the lower edge 14 of the armature, so that enough space remains to the bracket 2 to the hook-shaped projection 121 to hang in the Einitatinut 122 with the Ein cognitiveende 21.
- Bracket 2 in the hooked on the hook-shaped projections 121 state does not protrude beyond the lower edge 14 of the armature, which is the magnetic core enclosing bobbins not damaged or destroyed.
- the bracket 2 are, as shown in FIG. 3, approximately C-shaped in Cross-section formed, for example, spring steel and have a tight bent Einitatiende 21 on and a rounded bent approximately at right angles longer end 22 with Medicarekantetem end 23 for attachment on the receiving part.
- This attachment end 22 of the bracket 2 is Also provided through hole 20 for receiving a screw 3.
- the receiving part 5 is on top 19 of the armature 1 shown in FIG. 2 placed.
- the brackets 2 are assigned each attachment regions 52, 53 provided on the receiving part, Fig. 4, here additional insertion slots 51, 50 in order to appropriate pockets the receiving part 5, the strap ends 22 introduce.
- the screws 3 can then from the top into corresponding screw holes in the receiving part. 5 be screwed. This is a rigid connection of the armature 1 to the Receiving part 5 by means of two bracket 2 takes place.
- Brackets are attached to a receiving part, with each side of the Ankers two brackets 2 are provided, as shown for example in FIG. 7.
- a receptacle for an anchor that is attached with four straps is to see for example in Figs. 6a and 6b, the receiving part 7 has this corresponding to four receiving areas on its top four screw holes 71, 72, 73, 74 for fixing the brackets by means of screws.
- the Receiving part 7 further has on its upper side a bearing bore 70th for a bolt 6, see Fig. 7, on for the attachment of the receiving part with Anchor.
- bearing surfaces 75, 76 are provided for the proper installation of the armature 1.
- FIG. 5 shows the longitudinal section through the anchor fastening according to FIG. 7 shown.
- FIGs. 8a and 8b is another possibility of the embodiment of a Receiving parts 7 shown for attachment of the anchor by means of four brackets 2, wherein this receiving part of the receiving part 7 according to 6a, 6b characterized by a simpler surface design.
- this receiving part of the receiving part 7 according to 6a, 6b characterized by a simpler surface design.
- top damping components 8 applied become.
- the invention enables a simple anchor attachment, the versatile applicable is, whereby an economical production is given and in the a maximum utilization of the anchor volume with respect to the driving force is reached.
