Definitions

  • the invention refers to an electric hand tool with a bending protection cover for the power supply cable, in particular a combination hammer.
  • the Biegeschutz united after the DE29502859U a cable connection system the Biegeschutz with the strain relief by two bivalve rigid insertion shells positioned with a smooth rounded bell-shaped outer opening to a power supply cable and from the outside into a matching circular hole in the device housing can be inserted, they verklipsen positively and with radially inner clamping ribs the Firmly clamp the power supply cable.
  • the rigid introduction grommet thus formed is just no elastic Biegetikülle, as required for highly stressed electric hand tool machines.
  • the object of the invention consists in the technologically simpler realization of an electric power tool with a Biegeschutzülle and a strain relief.
  • an electric hand tool machine has a housing with at least two partial shells with an intermediate insertion opening through which a power supply cable is inserted, which is surrounded radially on the outside by an elastic bending protective sheath which is fixed in a form-fitting manner in recesses between the two subshells via a housing-internal radial collar, wherein in at least one subshell, a clamping rib arranged on the inside of the recesses is arranged for frictionally locking the power supply cable to this subshell.
  • mutually associated clamping ribs are present on both partial shells, whereby the frictionally locking fixing takes place symmetrically.
  • the clamping ribs are formed crescent-shaped, whereby during the assembly of the two partial shells, a substantially one-dimensional adhesion is exerted on the power cable, which deforms the cable cross-section permissible, but does not squeeze the inner leads to each other.
  • the two sub-shells are releasably secured against each other, further advantageous kraftformschlüssig as screwed, whereby the power cable can be changed in case of service.
  • the housing has at least two housing shells, in which the two partial shells are fixed in a form-fitting manner, whereby they can be pre-assembled with the power supply cable during assembly of the housing.
  • an electric hand-held power tool 1 in the form of a combination hammer driving a tool 2 with respect to an axis A comprises a housing 3 made up of two housing shells 4a, 4b, in which partial shells 5a, 5b are arranged, which can be fixed to one another via screwed connections 14.
  • FIG. 2 To Fig. 2 are the two partial shells 5a, 5b via fitting pieces 13 (FIG. Fig. 4 ) fixed in a form-fitting manner in the two housing shells 4a, 4b. Between the two subshells 5a, 5b is an insertion opening 6 ( Fig. 4 ) is present, through which a power supply cable 7 is inserted, at least partially outside the housing 3 ( Fig. 1 ) is surrounded by an elastic Biegetikülle 8 and in the housing 3 ( Fig. 1 ) stripped two power lines 11 releases.
  • Fig. 3 To Fig. 3 is the Biegetikülle 8 via a housing inner radial collar 9 positively in recesses 10 between the two sub-shells 5a, 5b set.
  • mutually associated clamping ribs 12 for frictional fixing of the power supply cable 7 to the partial shells 5a, 5b arranged.
