Definitions

  • the invention relates to an electrical connection device according to the preamble of claim 1; Such an electrical connection device is known from DE-OS 22 30 806.
  • a soldering lug for connecting a brush wire is inserted through the plastic bridge on a plastic bridge which can be locked in a bearing bracket of a collector motor on opposite sides of the collector in a winding base and at its other inserted end with a flat plug or a receptacle for a corresponding receptacle or a corresponding tab connector of an external connecting cable to be connected.
  • a simple electrical connection between the ends of a winding and a metal contact element with the inclusion of a winding support point which can be achieved with only a few components and can be assembled advantageously for automated production with only one main handling direction, is to be created.
  • the device according to the invention by simply plugging on a metal contact element in the direction of the winding axis of the winding wire wrapped around the plastic pin, electrical contacting between the contact element and the winding wire can be achieved at several contact points and at the same time the contact element can be fixed at the winding base;
  • a particularly good electrical contact, in particular in the case of a winding wire covered with an insulating varnish, results from the fact that, on the one hand, the plastic pin is wrapped several times in a helical shape by the winding wire and, on the other hand, the fork flanks at their contact surfaces with the wrapped winding wire with its insulation when plugged on of the metal contact element piercing sharp edges.
  • the plastic pin with a when plugging in of the metal contact element provide the fork flanks against the conical surface pressing against the wrapped winding wire, or the fork flanks in their end plug-on position plugged onto the plastic spigot outside of their contact surface in a material which is softer than the metal contact element Plastic pins are clawed and / or locked.
  • the plastic pin is in each case with a first guide opening, which is open on the plug-in side, for the plug-on end of the metal contact element and a second, the first Guide opening crossing slot-shaped guide opening for inserting and / or fixing a winding end of the winding wire.
  • FIG. 3 shows a winding base in the form of a plastic pin 1, which can be fastened, for example, to the brush bridge of a collector motor or the end flange of a coil former for a motor excitation coil or to the laminated core of a wound motor stator.
  • a winding wire 3 of an electrical coil is wrapped helically with several turns.
  • one winding end 32 is guided as an outer winding to the plastic pin 1, while the other winding end 31, which is to be connected to an outer connecting line via a metal contact element, is inserted into a slot-shaped guide opening 12 which is opened towards the plug-on contact element and is expanded there in a funnel shape by chamfered outer edges 29.
  • a guide opening 13 is provided into which the metal contact element shown in FIG. 1 in the form of a flat tongue 2 can be inserted with its fork-shaped plug-in end.
  • the winding end 31 inserted into the guide slot 12 is advantageously carried downward by the plug-in tab 2 when it is plugged in, with additional fixing in the end plug-on position by pressing the end of the winding 31 against the cone tip of the expanding cone surface 11 is possible.
  • the tab 2 With lateral step-shaped projecting shoulders 27, 28, the tab 2 can simultaneously press the winding turns of the wrapped winding wire close together.
