Definitions
- the invention is based on a power-driven hand tool according to the preamble of claim 1.
- features of claim 1 have the advantage that the electrical conductor is fixed and sealed such that its displacement or tearing can be excluded even in the event of strong vibrations.
- a leakage current barrier with a minimum leakage path of 4 mm is ensured for the electrical conductor in the hand-held power tool according to the invention with a normal housing wall thickness that is significantly smaller than 4 mm.
- FIG. 1 shows a partial side sectional view of a hand drill and FIG. 2 shows a section through the housing according to the exemplary embodiment according to FIG. 1.
- the handheld power tool shown in detail in FIG. 1 is a hand drill 1 with a housing 3 designed in a partial shell construction, which tapers to a spindle bearing point in the neck 4.
- the housing 3 has a housing wall 5 and accommodates a motor 7 and a gear 9.
- the motor 7 is operatively connected to a spindle 11 which carries a drill chuck 13.
- the spindle 11 also carries a pulse generator designed as a magnet 15.
- a sensor 17 is arranged closely adjacent to the magnet 15 in the housing wall 5 and is connected via an electrical conductor 19 to an electronic monitor and control unit 21 arranged in the motor housing 3 and having a setting wheel 22 for speed or torque control.
- the Electrical conductor 19 is guided to the neck 4 in the interior of the housing wall 5, ie in a channel 23 designed as a groove.
- the channel 23 is worked into the narrow side of the housing wall 5 of the housing partial shell 27 at an intended division level 30 to an adjacent, further housing partial shell 29.
- a first, bead-like rib 25 is formed in the contour of the end face of the housing wall 5 and runs like a raised bank alongside the channel 23.
- the two housing part shells 27, 29 are encompassed by a ring-like sleeve 32, which is held in a dovetail-like groove 34, which is incorporated into the outer contour of the housing 3 at approximately the same width along the dividing joint 36 or the dividing plane 30 is.
- the sectional view of the housing 3 shown in FIG. 2 shows the housing partial shells 27, 29 in the region of the meandering dividing joint 36.
- the channel 23 runs between the ribs 25, 26 of the housing partial shell 27 and that the electrical conductor 19 is fixed therein is held or clamped by the third rib 31 of the second partial housing shell 29.
- the ribs 25, 26 of the partial housing shell 27 protrude into recesses or in the channel 24 of the further partial housing shell 29 and thus hold the partial housing shells 27, 29 so that they cannot move relative to one another .
- first rib 25 of the first partial housing shell 27 projects into a channel 24 of the partial housing shell 29 and that the housing half-shells 27, 29 are thus secured to one another.
- channel 23 has a slot-like cross section and that the electrical conductor 19 is designed as a multi-core ribbon cable.
- the meandering or zigzag shape of the dividing joint 36 ensures that the creepage distance between the conductor 19 and the outer contour of the housing 3 is greater than 4 mm, without the housing 3 having to be stronger than normal at the dividing joint and that a wall thickness of approximately 2 mm is entirely sufficient here.
- a ring-like sleeve 32 can be seen, which holds the two housing part shells 27, 29 together and forms a reinforcement at a particularly highly stressed point in the housing 3, in which, for example, actuating elements for a gear shift or a switch between hammers or Bores are stored.
- a bore which essentially follows its contour and in which the electrical cable is arranged is arranged in the wall of the transmission housing.
- the electrical line cable is non-detachably encapsulated inside the housing wall.
- partial housing shells are double-walled with cavities for receiving cables or the like, so that light guide means, in particular image guide cables, and furthermore mechanical adjustment elements, in particular Bowden cables or shift linkages, are not from the outside visible, fixable.
