Definitions

  • screwdrivers are known. From the German utility model G 94 14 488.5 a screwdriver with a light source is known, in which one Battery, a halogen lamp with reflector and electrical cables in the commercially available handle of a screwdriver.
  • the disadvantage of this screwdriver is that it is difficult to manufacture because electrical cables on the holder of the halogen lamp and the battery must be soldered or otherwise attached. A replacement of Individual components such as cables or lamp holders are therefore not possible, furthermore, the production is very complex.
  • U.S. Patent No. 4,302,797 describes a tool in which the light in the Center of the tool part extending from the handle to the end is guided and thus illuminate the working area of the tool.
  • the disadvantage of this tool lighting is that the working environment cannot be adequately and sufficiently illuminated.

  • This illuminated screwdriver has the disadvantage that the contacts etc. must be arranged very complicated in the handle.
  • the circuit board is equipped with light sources and current sources. Consequently are no complex lines to install between the individual electrical components more necessary. It makes sense if the PCB has protection to protect it from damage in the event of frequent Protect extension and insertion.
  • the hollow handle on the inside is preferred designed that the circuit board - possibly with protection - along a prefabricated Guide device can be inserted in the handle, so that a simple Return of the electrical components in the handle is possible.
  • the light sources can be incandescent or halogen lamps. But it would be also light conductors or liquid conductors, light emitting diodes, light emitters, filaments or glow sticks or any other suitable light source that the Are known to those skilled in the art.
  • a light emission in the handle preferably two Light exits or three or more light exits can be included.
  • the Lux value depends on the chosen illuminant.
  • the tool has an insulation protection that differs from the Handle extends partially or entirely over the tool part. With such insulation, the tool can also be used in areas in which such insulation is advantageous, such as during assembly other electrical components.
  • the tool according to the invention advantageously has a removable one Handle cover on.
  • the end cover can be preferred Embodiment with an opening for a charging cable for an accumulator or can also be provided for operation by means of an external power source. But it is also possible to provide this cover without opening - this is particularly advantageous if an entry of Moisture should be avoided and a fully insulated Handle interior is desired.
  • This cover is preferably light removable, so that all components can be easily removed if necessary and are interchangeable.
  • the end cover is preferably equipped with a circumferential groove, so that he can use another tool, e.g. a small one Screwdriver or the removable tool part easily lifted off can be. But it is also any other type of attachment - for example over Screw connection or bayonet lock or through snap-in spring connections possible.
  • end cover so that it its engagement in the closed position is rotatable.
  • the tool preferably also has a device for phase testing with a display and an electrical conductor between the tool part and a display and another pole between which the display is switched. If necessary, an indication of the amount of current can also be given Show. This could be done using a digital display, for example.
  • the power source for the tool according to the invention can be a battery.
  • This is preferably attached to the circuit board in a holder.
  • the circuit board is preferably with provided with a mounting bracket to remove the circuit board from the handle of the tool.
  • the power source of the tool is an accumulator, it can do so that can be removed like a battery and then in one external charger can be recharged. But it can also be provided that an accumulator is firmly attached to the circuit board and then this via a charging cable that can be inserted through the end cover, can be loaded. In this case there is no opening in the hollow handle necessary to recharge the battery.
  • the tool can also be used directly with an external power source be connected and operated in this way. Under certain circumstances that is Tool via a transformer / power supply on the power source connected.
  • the tool according to the invention preferably has a switch that the Circuit between lamp and power source can close. Therefore are all obviously suitable to the person skilled in the art for this purpose Switches such as Rotary, toggle, pressure, rocker switch or piezo touch switch, Slide switch or step switch to the Adapt the amount of light to the respective environment.
  • Switches such as Rotary, toggle, pressure, rocker switch or piezo touch switch, Slide switch or step switch to the Adapt the amount of light to the respective environment.
  • An on / off switch is preferably recessed on the front side, so that it is not damaged.
  • the handle of the tool according to the invention essentially of an electrically insulating material.
  • the handle can preferably be a Kraftform-plus handle made of impact-resistant Plastic with integrated soft zones to be when working with the Screwdriver to protect the wrist and hand.
  • Plastic resists external forces and environmental influences, i.e. it is said to have high strength, heat resistance, toughness, etc. exhibit.
  • the handle can preferably also metals, ceramics Have glasses or other substances.
  • the handle conveniently has ergonomic shapes.
  • the handle preferably has all the necessary receptacles for PCBs on. Furthermore, stiffeners for frictional distributions or torsional forces may be included.
  • the tool can also be sprayed and Wet area can be used.
  • the handle on the Face of a holder like an insert holder e.g. one Hexagon on.
  • This can be done with a wrench or Ring wrenches can be turned without the need for additional special tools are.
  • This hexagon holder can be used on the tool part widths, for example a retaining spring can be adjusted. So different uses, depending on Size and length of the tool e.g. Imbus, Torx, Phillips, normal Slot also as rods that can be used on both sides or also angled Inserts are used.
  • the tool can also be designed so that the inserts cannot be replaced.
  • the inserts can also be magnetized if necessary or if so undesirable is made of a non-magnetizable material ..
  • the circuit board of the tool can advantageously be pulled out. So the circuit board can be easily removed from the tool handle and reintroduced, which may when replacing the Battery / accumulator is advantageous.
  • the plate preferably clicks into place, if she is in the right position.
  • the circuit board can be replaced to replace it be pushed out of the handle. Is also on the circuit board a mounting bracket attached, so the circuit board can be even easier, can be pushed out more conveniently and with better control.
  • the tool has a holder for the insulation protection in the handle, it can the insulation protection to be attached to the handle so that it does not can easily detach from the tool. So injuries from the Detachment of the insulation can be avoided.
  • This shot in the handle can For example, a short thread or another closure, such as. a spring lock or bayonet lock or the like.
