Definitions

  • the invention relates to a housing for an electrical component, in particular a relay, with a housing wall which closes off a hollow interior and which has sealing points, such as openings and gaps in the region of connecting pins and / or on their edge, according to the preamble of patent claim; see DE-A 28 51 329.
  • the object of the invention is to provide a housing of the type mentioned in the introduction, in which a particularly rapid and reliable distribution of a sealing compound from one or more filling points to the sealing points is ensured by an improved surface structure of the relevant housing wall.
  • such a housing has the features according to patent claim 1 to achieve the stated object.
  • elements of capillary systems which are known per se are combined by additionally forming a distribution rib in the distribution channels, which results in a system of double channels.
  • a distribution rib in the distribution channels, which results in a system of double channels.
  • the distribution channels open at approximately equal distances into a circumferential edge channel, the width of which is expediently less than the width of the distribution channels.
  • the distribution ribs of the distribution channels extend into the edge channel up to its outer wall. This outer wall is usually formed by the edge of a housing cap which is placed on a base part or a base or the like and forms an edge gap to be sealed with the latter.
  • special end channels can be provided which branch off from a distribution channel or from the edge channel. It is advantageous if the width of the capillary sections decreases from the respective filling container via the distribution channels to the edge channel or to the end channels.
  • the base body 1 shown in FIGS. 1 and 2 for a relay housing is largely flat and is provided on its upper side with projections 2 for fastening a relay system (not shown further).
  • the base body 1 has approximately round openings 3 for wire-shaped coil connection pins and rectangular openings 4, 5 and 6 for differently designed contact connection elements. After inserting the aforementioned pins, not shown, into the openings 3 to 6 and after the relay has been fully assembled these openings 3 to 6 are sealed with potting compound.
  • an edge gap 8 is to be sealed, which is formed all around between the base body 1 and a housing cap 7 from above, as shown in FIG.
  • a ventilation hole 10 formed in a protruding pin 9 should only be sealed in a manner known per se after the casting compound has hardened.
  • Distribution channels 13 branch off from these filling containers in the direction of the openings 3 or 4, 5 and 6 and the edge gaps 8.
  • Each of these distribution channels 13 is divided in the middle in the longitudinal direction by a distribution rib 14 into two sub-channels 13a and 13b, a sharp inner edge being formed in each case between the channel bottom and the side walls of the distribution channels or the distribution ribs.
  • the depth of the distribution channels corresponds approximately to the width of the sub-channels and, in an expedient embodiment, is approximately between 0.3 and 0.4 mm. Depending on the viscosity of the potting compound, other dimensions can also be favorable.
  • a peripheral edge channel 15 is also formed, the width of which is smaller than that of the distribution channels, if possible also less than that of the sub-channels.
  • a particularly favorable embodiment has an edge channel with a width between 0.2 and 0.3 mm.
  • the distribution channels are arranged so that they open into the edge channel at approximately equal intervals.
  • the distribution ribs are up to the opening 3 and from this further to the edge channel.
  • the distribution ribs 14 still extend over the width of the respective edge channel 15 to the outside thereof and thus abut the housing cap 7. To this The potting compound is guided very well into the marginal gaps 8.
  • small end channels 16, 17 and 18 with a particularly small width and thus particularly good capillary action are additionally provided, which branch off either from one of the distribution channels 13 or from the edge channel 8.
  • the gradual reduction in the channel cross section with increasing distance from a filling container ensures that the potting compound is sucked out quickly and completely from the filling container 11 or 12 and transported to the most distant sealing points.
  • FIG. 3 shows a somewhat modified embodiment of a housing element in the form of a base plate 21, which together with a cap (not shown) also forms a housing for a relay or a similar component.
  • a central filling container 22 is formed, from which distribution channels 23 with distribution ribs 24 lead to the various housing openings 25 and 26 with a round or rectangular shape and to an edge channel 28.
  • the distribution ribs 24 are each led into the openings 25 and 26 with vertical sections 27, the side walls 29 being designed to be somewhat beveled in this area. This results in a capillary action between the rib sections 27 and the respective breakthrough walls 29 up to the openings.
