Definitions

  • the present invention relates to an electromagnetic relay according to the preamble of claim 1.
  • Such relays are increasingly required in a so-called wash-tight version. This is achieved, for example, by the fact that the ceiling edge protrudes below the floor surface and this space is poured out with reversed relays.
  • the potting compound it is e.g. from DE-OS 28 51 329 and DE-GM 78 21 508 known to provide the bottom underside with a network of grooves which lead to the separating points between housing parts and housing parts and contact connections.
  • the object of the present invention is to enable a relay to be made wash-proof in a simple manner without harmful side effects from a greasy distribution of the potting compound, and the relay to be easily handled after potting.
  • the miniature relay 1 consists of an inner or lower, essentially cup-shaped, lower housing part 6 formed from two housing shells 2, 3 and a bobbin flange 4 of a bobbin 5 and a cup-like cover L 7 which overlaps the lower housing part 6 approximately to the bottom 8.
  • the two housing shells 2, 3 have an L-shape in cross section (see FIG. 2) and can also have an upper ceiling section to form a closed space, so that in cross section they have the shape of a U standing on a leg.
  • the metal parts 11 of the contact systems 12 and the connections 13 are molded in a manner known per se into the walls of the housing parts 2, 3 forming the side walls 9, 10 of the lower housing part 6 made of plastic.
  • the lower housing part 6 can also consist of a single plastic part or it can be composed of several parts, for example of two side walls 9, 10 and a central U-shaped part.
  • the individual housing parts can be held together by the cover 7 or previously connected by suitable measures, for example by plugging, gluing, welding by means of ultrasonic etc.
  • this consists of the bobbin 5, a winding 14, a magnetic core 15, one with the latter magnetically and mechanically firmly connected magnetic yoke 16 and a cap anchor 17 existing magnetic system of the relay 1 housed.
  • tabs 18 are formed on the bobbin 5 stand, with which it stands on the inner surface 19 of the bottom 8.
  • the separating points or butt joints 20 between the individual components must be tightly sealed.
  • this takes place from the inside in that at least one recess 21 is provided in at least one wall, in particular the side walls 9, 10 of the lower housing part 6, through which potting compound 22 can be filled in from the outside.
  • the latter runs on the inside at the bottom 8 of the lower housing part 6 and, due to the capillary effect, runs into the separating points 20 of the relatively closely adjacent components 2, 3.
  • At least one side wall 2, 3 and / or the bobbin flange 4 there is at least one opening 23 which extends down to the surface 19 of the base 8 and through which casting compound 22 can flow from the inside to the outside.
  • the openings 23 can extend as a slot 25 from the lower edge of the recess 21 down to the surface 19 of the base 8 or the openings 23 can be formed by small bores 26 which are provided above the base 8 but up to the surface 19 reach down.
  • the openings 23 can be distributed around the circumference in such a way that they can run evenly to all the separating points 20 in a certain time unit.
  • the potting compound 22 it is advantageous to choose one which has a lower viscosity when the temperature rises. As a result, after pouring the same and fitting the cover 7 by heating, a faster and more uniform distribution and a good flow in the separating lines 20 or separating surfaces can be achieved.
  • the potting from the inside can be used to remove internal parts, e.g. to anchor the coil flange 26 to the floor 8.
  • the stand tabs 18, which stand on the surface 19 and which are also embedded in the casting compound 22, can be formed on the bobbin 5, in particular on the flange 27. This guarantees vibration-free retention of the magnet system.
  • cutouts 21 are arranged in a side wall 9 and / or 10, they are arranged in such a way and / or the metal parts 11 are provided in a stepped or oblique manner such that they do not run through a cutout 21.
