Definitions

  • the invention relates to a receiving housing for a hand tool, referred to in the preamble of claim 1. Art.
  • a hand tool such as a drill or chisel hammer, a circular, jigsaw, a grinder, a screwdriver or the like
  • electronic devices are provided in a receiving housing.
  • a receiving housing comprises a first housing part having a opening and a second housing part for closing the opening, wherein the housing parts form a receiving space.
  • a board equipped with electronic components is arranged at a distance from the opening.
  • a receptacle housing for an electric hand tool which comprises a first trough-shaped housing part having an opening, in which a printed circuit board equipped with electronic components, such as control components, optical display elements or plugs, is arranged at a distance from the opening.
  • a printed circuit board equipped with electronic components such as control components, optical display elements or plugs
  • the opening in the first housing part is covered with a cover formed as a second housing part, which is fixed via a latching mechanism on the first housing part.
  • the cover plate is transparent or translucent, at least in the region of the optical display elements, so that the light emission thereof is visually perceptible.
  • a disadvantage of the known solution is that between the first and second housing part moisture or dust can penetrate into the receiving space, resulting in a malfunction of the electronics.
  • the receiving space is filled after merging the housing parts with a potting compound.
  • a disadvantage of the known solution is that from the outside of the device visually perceptible or mechanically accessible electronic components are also completely poured.
  • the object of the invention is to provide a receiving housing of the type mentioned, in which individual electronic components are visually perceptible or mechanically accessible from the outside of the device, wherein the receiving space to protect the electronics is pourable.
  • At least one sleeve section is provided on the second housing part, the free axial length of which corresponds at least to the distance between the circuit board and the opening.
  • the at least one sleeve section is arranged on the second housing part such that, for example, an optical display element arranged on the circuit board is visually perceptible from the outside or a plug arranged on the circuit board is mechanically accessible from the outside.
  • the axial extension of the at least one sleeve portion is selected such that after merging the housing parts, at least the free end of the free end portion of the sleeve portion is pressed against the side of the board, wherein the circumferential sealing zone is provided.
  • the remaining space of the receiving space is filled after the merging of the two housing parts with a suitable potting compound, wherein the circumferential sealing zone prevents entry of the potting compound in the created by the at least one sleeve portion interior and thus the existing electronic components in the interior.
  • an access opening to the interior formed by the at least one sleeve portion in the second housing part is provided, through which an electronic component arranged on the circuit board, such as a plug, is mechanically accessible from the outside.
  • an electronic component arranged on the circuit board such as a plug
  • the accessibility of the electronic component is not mandatory, if the second housing part is at least in the region of the at least one sleeve portion transparent or at least translucent.
  • At least the free end portion of the at least one sleeve portion is made of an elastically deformable material, whereby the free end easily slips back when merging the two housing parts, while a secure seal between the receiving space and the board and thus created by the at least one sleeve portion Interior guaranteed.
  • an elastomer is used as the elastically deformable material.
  • the whole at least one sleeve portion or even the entire second housing part is made of an elastically deformable material.
  • the at least one sleeve section preferably has an undercut arranged on the circumference.
  • the undercut is advantageously formed tuned to the configuration of the free edge of the first housing part and allows easy fixing of the second housing part to the first housing part via a latching connection. This locking connection holds the two housing parts during filling of the remaining receiving space with the potting compound in position and seals the opening in the first housing part and the interior against the escape of the potting compound from the receiving space.
  • the at least one sleeve portion is funnel-shaped widening in its free end, so that when merging the two housing parts of the free end portion of the at least one sleeve portion for a secure seal to the board is pushed outwards and at least partially rests flat against the side of the board.
  • the wall thickness of the at least one sleeve portion is designed to be decreasing towards the free end, so that the free end region can easily be deformed when the two housing parts are brought together and simply applies to the printed circuit board under prestressing.
  • the receiving housing 11 shown in Figures 1 to 3 for a, not shown here hand tool comprises a trough-shaped, first housing part 13 having a slot formed as an opening 15, and a second housing part 14 for closing the opening 15, wherein the housing parts , 14 form a receiving space 16.
  • a board 20 equipped with electronic components 17, with LEDs 18 and with a plug 19 is arranged at a distance A from the opening 15.
  • the free axial length L of the sleeve portions 26 at least equal to the distance A, the free end portions 28 of the sleeve portions 26 are to form three interiors 27 in the assembled state of the first housing part 13 and the second housing part 14 on the side 21 of the board 20 via a circumferential sealing zone and seal the receiving space 16 to the interior 27 from.
  • Access openings 29 to the interior spaces 27 are respectively provided in the second housing part 14, so that the LEDs 18 coming to lie in the interior spaces 27 are visually perceptible from the outside and the plug 19 is mechanically accessible from the outside.
  • the free end portion 28 of the sleeve portions 26 is made of an elastomeric material and widens funnel-shaped, wherein the wall thickness of the sleeve portions 26 is formed to the free end decreasing.
  • the sleeve sections 26 have a hyperbolic outer contour in their axial extent.
  • the sleeve sections 26 have a recess arranged on the circumference, which recess is designed in accordance with the configuration of the free edge 32 of the first housing part 13.
  • the free end portion 28 of the sleeve portions 26 is held during filling of the receiving space 16 with the potting compound 23 through the filling opening 22 in the first housing part 13 with the side 21 of the board 20 in Appendix.
  • the potting compound 23 fills the remaining after merging of the first housing part 13 and the second housing part 14 receiving space 16, wherein the visually unnoticeable and mechanically inaccessible electronic components 17 completely and the board 20 except in the area of the LEDs 18 and the plug 19 are poured , Thus, no moisture or dirt can penetrate into the receiving space 16, which could cause a malfunction of the electronics.
