Definitions
- the invention relates to an electromagnetic relay with a between the magnet system on the one hand and the contact arrangement on the other hand arranged insulating wall, which a Has a plurality of insulating layers.
- the Invention a method for producing such a relay.
- the insulation distances can be achieved by simple insulation realized by means of a one-piece insulating wall be, which then a certain minimum thickness may fall short.
- the insulating wall from, for example, at least three individual layers to form, then the wall thickness of these individual layers is no longer required. It must then be for the individual layers, the dielectric strength is separated be detected.
- a relay of the type mentioned is already in the Utility model DE 8914910 U1 described.
- the film has to be added Part manufactured, cut and inserted. To ensure that this film can be inserted easily, the gap width in the pocket cannot be arbitrary be chosen small.
- the object of the present invention is therefore a relay to design the type mentioned so that an insulating wall designed with several layers as thin as possible and on can be produced as simply as possible.
- this is achieved in that the insulating wall from a wall base with at least one, in one insulating gap provided for an insulating layer is formed and that the insulating layer in the insulating gap through liquid filled and subsequently hardened Insulating material is formed.
- these Wall base also one-piece part of a relay base body can be, for example, which carries the magnet system and / or the contact elements records.
- One or more additional ones Insulating layers are made by simply pouring the liquid Isolierstoffs formed in the gap or in the column. Depending on the circumstances, this does not even require an additional one Manufacturing step, since mostly potting compound anyway must be filled in to seal the relay.
- An additional insulating layer can, for example, also by filling the liquid insulating material into a basic body gap take place, otherwise for receiving a contact carrier is provided. It only has to be ensured that the contact carrier in the gap at the required by the Insulating wall is positioned on the far side, so that the contact carrier the formation of the multilayer insulating wall not affected.
- the width of the isolation gap can be chosen as small as the mold, d. H. the smallest possible knife width of a mold insert.
- the liquid insulating material can vary depending on the circumstances and according to its viscosity due to its own gravity in the Insulation gap flow or be injected under pressure. The capillary action of the insulating gap also helps liquid insulating material up to the inner end of the gap promote. It is expedient in the area of the inner end a vent is provided in the wall base.
- a method according to the invention for producing such Relay consists in that a base body with a bottom part, an insulating wall protruding upwards from the base part with plug-in channels for contact carriers and at least one Insulating gap in the area of the insulating wall made of insulating material is that the magnet system and the Contact arrangement are attached and that finally the Insulated gap sprayed with a liquid insulating material and this insulating material is then cured.
- the relay shown in Figures 1 and 2 has one Base body 1 made of insulating material on which a magnet system with a coil 2, an angled yoke 3 and an armature 4 is arranged.
- the armature 4 operates via a slide 5 a contact spring 6, which in a via a spring support 7 Slot 8 of the base body 1 is anchored.
- An NC contact carrier 9 is anchored in a slot 10 of the base body, correspondingly a make contact carrier 11 in one Slot 12 of the base body 1.
- An insulating material cap 13 forms a closed housing together with the base body 1.
- a partition 14 is also formed on the base body 1, which together with a cap wall protruding downwards 15 a two-layer insulation between the yoke and the forms the contacting end of the make contact carrier 9. In this area, the distance is also relatively large anyway, so that the required insulation distances are maintained.
- the distance between the kink area is critical 16 of the yoke 3 and the NO contact carrier 9.
- This Normally open contact carrier 9 is opposite the contact End slanted to the right to a desired large one Distance between the pins of the contact elements receive.
- the insulation requirement with three insulation layers is to be met in the basic body 1 in the mentioned critical area an isolation gap 17 cut out, the subsequent is filled with liquid insulating material. After this This insulating material forms a gap in the gap 17 additional insulating layer between those formed by the base body Wall layers 18 and 19. So when injecting or Filling the additional liquid insulation material no Air build-up inside the insulating gap 17 is to A ventilation opening 20 is provided inside the base body. This allows excess insulation material in the Reach cavity 21 and harden there.
- the mounting slot 10 of the NO contact carrier 9 insulation material are filled, to form another layer of insulation.
- the contact carrier 9 within of the slot 10 positioned on the wall away from the yoke so that the filled insulation material actually as an effective insulating layer between the contact carrier 9 and the yoke 3.
- the additional insulation material to form the additional insulating layer can also be used at the same time Potting the base side to seal the contact carrier slots 8, 10 and 12 are introduced.
