Definitions

  • the invention relates to a mains-operated hand tool device, in particular a hammer drill, a chisel or impact drill, a motor-driven saw, in particular a jigsaw or saber saw, or a separating or grinding device, in particular an angle grinder.
  • the hand tool includes a housing from which extends a power cord for connection to a power grid away, and a connection device. This is arranged at a passage opening of the housing, from which the power cord exits from the housing.
  • the connection device has electrical connection means, to which the power cable can be connected, as well as fixing means, on which the power cable can be fixed.
  • a closable by a mounting cover mounting opening of the housing is provided. By spacing this mounting cover from the housing, the connection device can be made accessible, for example during assembly or for repair or replacement purposes of the power cable.
  • a disadvantage of the known machine tool is that the service cover must be made relatively large in order to allow easy access to all connection and Festlegeschn. On the other hand, the stability of the housing can be noticeably weakened if the service cover is designed too large.
  • the present invention has for its object to avoid the disadvantages mentioned in a hand tool and to allow easy accessibility of the connecting device with little weakening of the housing.
  • the object is achieved in that the connecting means and the fixing means are at least partially displaceable out of the housing interior through the mounting opening.
  • the connecting means and fixing means are substantially freely accessible.
  • the mounting opening only needs to be just designed so that the relevant for mounting and dismounting of the power cord connecting means and fixing means can be moved through them. This makes it possible to dimension the mounting hole very small and thereby maintain sufficient stability of the housing. Due to the free accessibility of the relevant connecting means and fixing means on the outside of the housing a particularly convenient assembly, disassembly or maintenance of the power cord is made possible simultaneously.
  • the connecting means and the fixing means are held on a support element.
  • This support element is between an operating position, in which the connecting means and the fixing means are arranged inside the housing, and an open position in which the connecting means and the fixing means are at least partially arranged outside the housing interior, displaceable.
  • the carrier element is connected to the mounting lid.
  • the connecting device is moved through the mounting opening. In this way, the connecting device is made particularly quick and convenient access.
  • the passage opening is provided on the mounting lid.
  • the definition of the power cord is done solely on the mounting lid, which further simplifies handling.
  • the connecting device is biased in the direction of the open position.
  • the connecting device is automatically removed from the housing when releasing the mounting lid in the open position and held in this force-locking relative to the other hand tool. In this way, a stable position of the connecting device is ensured in the open position, which ensures comfortable handling.
  • the connecting device is biased by a resilient protective casing of a device-side wiring.
  • the connecting device in the open position on an end stop.
  • a favorable position of the connecting device can be predetermined, in which the connecting means and fixing means can be accessed particularly well.
  • the mounting lid thus remains in the open position on the power tool, thereby avoiding that the mounting cover is lost.
  • end stop is formed by the protective jacket. In this way, no separate end stop must be formed, which reduces the manufacturing cost.
  • guide means are advantageously provided on the support element, which cooperate with housing-fixed counter-guide means and thereby guide the support member relative to the housing in translation. This gives a drawer-like guidance of the support element and thus the entire connecting device. This can be changed in a comfortable way between the operating position and the open position, wherein the connecting device is held stable in two positions relative to the housing. In this way, both a comfortable assembly or disassembly of the power cord and a safe operation can be ensured.
  • Fig. 1 shows a mains-powered hand tool 2, in the form of a chisel device, which has a housing 4.
  • a power cord 6 is connected, which is connected at a free end 8 with a power plug 10.
  • the power cable 6 is connected to a connecting device 14.
  • the connecting device 14 for fixing the power cord 6, a spout 16, which covers a portion of the power cord 6 and is connected to a mounting lid 18, and formed as a cable clamp fixing means 20, which are arranged on a support member 22.
  • a passage opening 23 is inserted, via which the power cord 6 exits from the housing 4.
  • the carrier element 22 is connected to the side facing away from the spout 16 side of the mounting lid 18 with this.
  • connection means 24 in the form of luster terminals are provided on the carrier element 22.
  • connection means 24 are cable-side strands 26a of the power cord 6 with device-side strands 26b of a device wiring 28 electrically connected.
  • a clamping receptacle 30 is further formed on the support member 22, in which a protective jacket 32 of the device wiring 28 can be attached.
  • guide means 34 are provided, which with groove-shaped counter-guide means 36 (see Fig. 4 ) of the housing 4 cooperate and thereby allow a guided translational movement of the connecting device 14 relative to the housing 4.
  • the guide means 34 may, as shown, be formed by edges of the carrier element 22 or alternatively by ribs formed thereon.
  • the connecting device 14 is held in the open position by the protective jacket 32 of the device wiring 28 on the housing 4.
  • the protective jacket 32 As in Fig. 5 shown curved.
  • a restoring force R is generated, which acts on the clamping receptacle 30 of the support member 22 and biases the connection assembly 14 in the direction of the open position.
  • the connection assembly 14 shifts automatically after loosening the mounting screws 38 in the open position according to Fig. 4 ,
  • the length of the protective jacket 32 is dimensioned such that it acts as an end stop in the open position and thus prevents the guide means 34 from slipping out of the counter-guide means 36.
