Definitions

  • the invention relates to a strain relief component, for supply lines provided with insulation, in particular an electric motor, with a capacitor for electromagnetic interference suppression, a contact element being provided which is in electrical contact with the capacitor.
  • Such a component is known from DE 34 34 429 A1.
  • the component is part of an electric motor here.
  • the strain relief function serves to reduce the mechanical load on the connection points of the electrical supply lines.
  • a capacitor is used which is contacted, for example, on the brush holder of the electric motor and on the motor housing, for example by being clamped between the pole housing and the bearing cover.
  • the strain relief component shown in the cited document also simultaneously connects electrical leads to separate connections of the electric motor.
  • DE 33 14 412 A1 discloses a component for mounting an interference suppressor which is connected at one end to the brush holder of an electric motor and at the other end to the motor housing. At one end the component contacts an interference suppression capacitor connected to the brush holder of the motor.
  • a disadvantage of the solutions described is the complex assembly of the interference suppression capacitor and the component for strain relief.
  • the object of the invention is to simplify the assembly of a component for tensile stress and an interference suppression capacitor.
  • the component according to the invention with the features of claim 1 offers the advantage that the strain relief component and the capacitor can be assembled in one work step. Since the contact is made via a contact element that penetrates the insulation of the supply line, there is no need to attach the capacitor to an exposed electrical connection of the supply line, so that the connection of the capacitor is e.g. no longer has to be in the immediate vicinity of the brush holder. This increases the freedom to position the component for strain relief and the capacitor.
  • the contact element is a mandrel arranged in the strain relief component.
  • a metal mandrel is inexpensive to manufacture and can be easily integrated into the strain relief component.

  • the mass contact takes place via a mandrel arranged in the tension control.
  • the ground connection can also be contacted via a mandrel connected to a capacitor connection. This enables the motor housing to be contacted even if it is painted or non-electrically coated, since the mandrel can penetrate a coating and make electrical contact with the metal of the motor housing.
  • the strain relief component contains a retaining clip by means of which the capacitor is fastened in the strain relief component.
  • the mandrel is inserted into the strain relief component, and the strain relief component has connecting elements for clipping connection to the feed lines and to a component of an electric motor that is connected to ground, so that the strain relief component can be connected to the leads and the component of the electric motor that is connected to ground by clipping on ,
  • the capacitor can easily be fastened in the tension component by means of the holding clips. Due to this construction, the capacitor and the mandrel can be preassembled in the strain relief component, and the assembly comprising the capacitor, mandrel and strain relief component can be mechanically mounted on the feed lines and the motor housing.
  • the strain relief component is preferably made of plastic and can be manufactured in an injection molding process.
  • FIG. 1 shows a three-dimensional partial view of a motor housing of an electric motor and of a strain relief component according to the invention
  • FIG. 2 shows a three-dimensional representation of a strain relief component according to the invention
  • FIG. 3 shows a three-dimensional representation of a strain relief component according to the invention with a capacitor inserted
  • FIG. 4 shows a three-dimensional view of a strain relief component according to the invention with inserted capacitor and inserted mandrel;
  • FIG. 5 shows a three-dimensional view of a mandrel for use in a strain relief component according to the invention

  • FIG. 7 shows the components shown in FIG. 1 in a three-dimensional view.
  • FIG. 1 shows a strain relief component 10 according to the invention with an inserted capacitor 12 in its assembled state, in which the component 10 is clamped between the feed lines 14 and the pole housing 16 of an electric motor.
  • the electrical leads 14 are connected to a brush plate 18 of the motor via connecting elements 20.
  • the view shown in Fig. 1 shows the electric motor from above and outside.
  • the strain relief component has connecting clips 22, which are shown in more detail, for clipping onto the supply lines 14. On the outside
  • Ends of the component for strain relief 10 are two fork-shaped Assembly clips 24 with which the strain relief component 10 can be clipped onto the pole housing 16 of the motor.

  • the capacitor 12 is held by the hook-shaped holding clip 26 and additionally by a projection 46, which is arranged next to the hook-shaped holding clip 26, during the stops 32 and 34 at both ends of the capacitor 12 prevent the capacitor 12 from shifting in the longitudinal direction.
  • the wall 36 prevents the capacitor 12 from moving laterally, so that it is also secured in the strain relief component 10 against shaking stress.
