Definitions

  • the present invention relates to electrical connectors and, more particularly, a suppressor connector for an electric motor, for example of the type used on board land motor vehicles, and a method of manufacturing such a connector.
  • the electronic components used and their location mean that they are bulky and annoying and that in this way they harm the reduction in the overall dimensions of the motors and increase the cost of their manufacture.
  • the object of the invention is to remedy this type of drawback with the aid of an improved connector which incorporates electronic components of a circuit for filtering parasites generated by the collector and the brushes of an electric motor. direct current.
  • the subject of the invention is a suppressor connector for an electric motor comprising in particular an electrically insulating body, the outer wall of which is provided with passages for preferably flat conductive pins intended to provide an electrical junction.
  • This connector is remarkable in that its body comprises an interior chamber which is intended to receive at least one electronic component and into which at least partially penetrates an internal part of the pins, at least one housing which is intended to receive another electronic component and which opens on the one hand directly above this internal part of one of the pins and on the other hand on the external wall of the body, at least one orifice for the passage of an electric cable intended to provide an electrical junction with this internal part of the pins, and in that these pins are initially presented in the manner of an H with two parallel branches temporarily connected by a breakable frangible transverse bridge and are arranged relative to this body so as to have this internal part made only of a part of the branches and an external part made of the rest of these branches and of this bridge, and in that this body is overmolded s ur this internal part of the pins
  • the invention also relates to a method for the manufacture of a suppressor connector for an electric motor comprising in particular an electrically insulating body, the outer wall of which is provided with passages for preferably flat metal pins intended to provide an electrical junction, of the type indicated before.
  • a suppressor connector for an electric motor essentially comprises a body 10 and pins 20.
  • Such a connector is intended to be electrically connected to a conductive cable 30 in order to be used on a brush holder plate 40 of a direct current electric motor of any conventional current type, for example of the type of those mounted on board land motor vehicles for driving, for example, fan units or window regulators.
  • the body 10, made of a suitable electrically insulating material, is delimited by an outer wall 100.
  • This outer wall 100 is defined by two opposite faces 101, two opposite sides 102 and two opposite sides 103.
  • the body 10 is in the form of a ring arc, the two opposite sides 103 of which are at least partially curved, one convex and the other concave.
  • the concave side 103 is preferably provided with a flat 1030.
  • passages 11 intended to receive the pins 20, an interior chamber 12 intended to receive at least one electronic component of a suppressor circuit of any suitable conventional type such as , for example, a self-inductance 120, as well as at least one housing 13 which opens, on the one hand directly above the internal part of one of the pins 20, as will be understood below, and, on the other hand on the outer wall 100 of the body 10.
  • Each housing 13 is intended to receive another electronic component of the interference suppression circuit such as for example a capacitor 130, as will be understood later.
  • the body 10 also has at least one orifice 14 for crossing the electric cable 30.
  • the outer wall 100 of the body 10 is provided with a groove 1010 on one of the faces 101 and the housings 13 open therein, as well as two grooves 1020, each arranged on the 'one of the opposite sides 102.
  • the pins 20 are initially presented in the manner of an H with two parallel branches 21 momentarily connected by a transverse bridge 22, frangible breakable. These preferably flat pins 20 are arranged relative to the body 10 so as to have an internal part 201 made only of part of the arms 21, and an external part 202 made of the rest of the arms 21 and of the bridge 22.
  • the cable 30 is of any conventional type, for example with an insulating sheath 31 and conductors 32 if necessary also individually insulated. This cable is preferably overmolded in the body.
  • the electrical junctions of the electronic components and of the cable with the pins are ensured in any common conventional manner, for example by contact, welding, crimping, etc.
  • the housings open into the groove, the orifice is located on one of the faces and the passages are located on one of the sides and preferably the concave side.
  • the pins 20 are first cut out with an H-shaped configuration. This cutting is obtained by any conventional technique and is optionally associated with a shaping operation obtained simultaneously or during another operation, for example to ensure that the internal and external parts of the pins are not coplanar, as illustrated.
  • the body is molded on this part of the two parallel branches which is electrically connected to the electronic component and to the cable, in an electrically insulating material so as to form a chamber in which this electronic component is housed and an orifice for the cable crossing.
  • this body traps the internal part of the pins and leaves visible the rest of the branches and the bridge which together form the external part while observing that during this overmolding operation the housings which open out are cleaned.
  • housings are obtained in any suitable manner using movable or non-movable cores, arranged in the imprint of a mold.
  • the frangible breakable bridge is separated from the branches in order to eliminate the electric short circuit formed by this bridge between the two branches of the pins.
  • an anti-interference electrical connector has been manufactured which in particular solves one of the difficulties linked to the installation in particular of the capacitors which are relatively fragile and delicate to implement, and which in particular resist harm to the pressure and temperature constraints which manifest themselves when the body is overmolded on the pins and the cable.
  • these electronic components are physically and electrically associated with the connector only after the overmolding operation.
  • such a connector is associated with the brush holder plate 40 in which there are in particular a central opening 41 intended to allow free passage to a part of the motor such as the manifold, corridors 42 intended to receive graphite-based brushes or carbon brushes, and electrical fittings 43.
  • This brush-holder plate is of any conventional type.
  • a suppressor connector according to the invention to such a brush-holding plate is made in any suitable manner, for example by plugging into a suitably suitable base, by welding, by crimping, etc.
