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-A-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 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 provided with a first guide opening, which is open on the plug-in side, for the push-on end of the metal contact element and a second, slot-shaped guide opening, which crosses the first guide opening, for inserting and / or fixing a winding end of the winding wire.
  • 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 can be inserted in the form of a flat tongue 2 with its fork-shaped push-on end.
  • Fig.5 shows the partially in the inner winding of the looped winding wire 3 with simultaneous guidance through the guide opening 13 inserted flat tongue 2.
  • the fork-shaped push-on end of the flat tongue 2 is dimensioned such that the outer surfaces provided with sharp edges when the flat tongue 2 is plugged through the enamel insulation of the winding wire 3 and thereby an electrical contact between the Ensure flat tab 2 and the wrapped winding wire 3 securely.
  • the plastic pin 1 in the area of the first slot-shaped guide opening 13 is advantageously provided with a fork flanks 21 when the flat tongue 2 is plugged on, 22 against the wrapped winding wire 3 pressing expanding cone surface 11.
  • 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.

Claims (9)

1. Dispositif de liaison électrique installé entre le fil de bobinage (3) d'un enroulement électrique et un organe de contact métallique pour un conducteur extérieur de raccordement en un point de support de l'enroulement réalisé en un matériau électriquement isolant, caractérisé par le fait qu'un embout en matière plastique (1), prévu en tant que point de support de l'enroulement, est entouré par le fil de l'enroulement (3) et qu'un organe de contact métallique, muni d'une extrémité d'enfichage en forme de fourche (languette d'enfichage plate 2) peut être amené en contact avec le fil de l'enroulement (3), par l'intermédiaire d'au moins deux flancs (21, 22) de la fourche, qui peuvent être écartés lors de l'enfichage en étant appliqués contre le fil de l'enroulement.
2. Dispositif de liaison électrique suivant la revendication 1, caractérisé par le fait que l'embout en matière plastique (1) est entouré d'une manière multiple selon une disposition hélicoïdale par le fil de l'enroulement (3).
