Definitions

  • the present invention relates to a housing for an electrical assembly, in particular a housing which is suitable for the assembly of a prefabricated assembly.
  • cables that supply different modules can be combined in sections to form a cable harness. If such an assembly is to be housed in a housing, the cable must be led out.
  • This may be enabled in a clamshell housing in that, from the facing edges of the two shells, at least one is provided with a notch through which, when the housing shells are assembled and the assembly is placed between the shells, the cable passes.
  • the object of the invention is to provide a housing for an electrical assembly, on the one hand has a sufficiently large opening to pass the assembly together with a cable connected thereto, but on the other hand, a fixation of the cable in the opening and preferably even a seal with the opening minimal work required.
  • the object is achieved by providing in a housing for an electrical assembly with a shell and a cover closing an open side of the shell, in which an opening for a connecting cable of the electrical assembly is formed in a wall of the shell, one with an open-edge first Slot provided first sleeve of the lid is anchored in the opening.
  • the sleeve By the sleeve is inserted into the opening, it performs two tasks simultaneously, on the one hand, the fixation of the lid on the shell, whereby a closed housing is obtained, on the other hand, the fixation of the connecting cable in the opening, since the connecting cable, although the Sleeve engages in the opening, can only extend through the slot of the latter.
  • the first sleeve is preferably guided in a second sleeve of the shell surrounding the opening.
  • This second sleeve is preferably provided on at least part of its length with an open-edge second slot through which the cable extends when the lid is mounted. If an overlapping region of the two slots is dimensioned such that it is filled by the cable extending through the opening, the intermeshing sleeves additionally achieve a sealing effect, for example with respect to insulation material.
  • a clamping of the cable in the two slots favors the sealing effect and also leads to a discharge of the connection between the cable and electrical assembly relative to outside the housing acting on the cable tensile forces.
  • the first sleeve preferably bears on its edge facing away from the lid a latching projection which engages behind an edge of the second sleeve facing away from the lid.
  • the first sleeve may have a plurality of slots distributed over its circumference. Of these slots, generally one is the above-mentioned first slot through which the cable passes.
  • the first sleeve fills the free cross section of the second sleeve so that a medium to be sealed against can not penetrate between the sleeves.
  • a round cross-section of the sleeves is useful to facilitate insertion, since it allows in an initial phase of insertion of the sleeves into each other, a relative rotation of the sleeves.
  • the shell is provided with a circumferential sealing lip, the shell as a whole can be inserted tightly into a wall opening.
  • a cable holder encircling the housing makes it possible to clearly accommodate any excess lengths of the cable.
  • the lid For fixing and / or fixing the position of the lid to the shell, the lid preferably carries a contact with side walls of the shell in its interior engaging circumferential ridge.
  • the cover is articulated by a hinge in a fixedly connected to the second sleeve base part and a pivotable against the base flap.
  • the flap can be swung open, access to the interior of the shell, for example, to repair the head accommodated therein, is possible.
  • the above-mentioned web is advantageously interrupted at the level of the joint.
  • the cable bushing can serve to accommodate a temperature sensor in the hollow body, which, for example, in a refrigeration device for the Temperature control of the interior can serve.
  • a lighting means for illuminating the interior can be accommodated in the housing.
  • the invention is also an electrical device with a device housing, in which a housing of the type described above is inserted, preferably a household appliance, in particular a refrigerator, with an interior enclosing device housing, in which such a housing is mounted on an inner wall of the device housing ,

  • a projecting into the interior of the column 13 is formed, which carries a latching projection 14.
  • a recess 16 of the base plate 2 can be seen, which extends from a slot 9 opposite edge region of the opening 7 to an edge of the base plate 2.

  • each one of the side wall 4 facing projection 17 supporting arms 18 define between them and the side wall 4 a Jardin arrangementsweg on which the emerging from the opening 7 cable 10 can be wrapped around the side wall 4 one or more times.
  • Such an attachment of the cable 10 is useful when the cable 10 is passed through the heat insulating foam layer on a short path, since the wound around the side wall 4 portion of the cable is exposed to substantially the same temperature as the temperature sensor 1 1 and this before a Falsification of the measured value by in the cable 10 itself passed through the insulating foam layer heat protects.

  • This assembled state is shown in FIG.
  • the length of the slots 9, 27 is dimensioned such that a cross-sectional area on which both overlap in the latched state corresponds exactly to the cross-section of the cable 10 passed or preferably has a slight undersize in order to clamp the cable 10 in the slots 9 To ensure 27.
  • the latching hook 30 of the flap 25 engages in the assembled state behind the locking projection 14 of the column 13.
