Definitions

  • the present invention relates to an electrical connector for insulated conductive wires. It finds application in the field of connection of wound dynamoelectric machines.
  • the set of coils therefore comprises a plurality of insulated conductive wires which must be electrically connected directly or not to the power supply in the case of a motor or to the load in the case of a generator.
  • the present invention provides an answer to these various imperatives, in particular by proposing a connector of an advantageous cost price and easily mountable by an automatic chain.
  • the invention proposes an electrical connector for windings of dynamoelectric machines for connecting thin, free insulated conductor wires to a printed circuit.
  • a connector includes electrically insulating support means which keep the insulated wires initially free and conductive lugs for connection by displacement of insulator at any point along the length of each wire and for connection to a printed circuit board inserted in the connector.
  • a connector according to the invention always comprises a first housing 1 which comprises an upper plate 5 and a lower plate 6.
  • a slot 7 made in the upper plate 5 and a slot 8 in the lower plate 6 make it possible to position the insulated conductive wire 4 to be connected.
  • a terminal 3 made of a conductive material suitably chosen according to mechanical and thermal requirements, is arranged in a second housing 2.
  • the terminal 3 comprises a first part 13 for connection of the insulated conductive wire 4 to the terminal 3 and a second part 14 for connection of the terminal 3 to a printed circuit not shown.
  • the second box 2 is inside the first box and includes means 16 for mechanical attachment to the first box.
  • the second housing has an upper plate 9 and a lower plate 10.
  • the second housing 2 can carry spacers 11 between two successive lugs 3 if the connector has many lugs of connection.
  • the connector can, at least for the two housings 1 and 2, be made of an insulating plastic material, the housings being obtained by molding.
  • Each terminal 3 includes a means 15 for fixing to the housing 2.
  • This fixing means can be of the snap-on type.
  • FIG 2 there is shown a first part 13 of a particular shape for making the connection of the terminal 3 to an insulated conductive wire 4.
  • the wire 4 being an insulated wire
  • the first part 13 of the terminal 3 has a flat part 18 connected by an elbow to a flat part 19.
  • the two flat parts 18 and 19 are in the plane of the drawing. This offset allows the insertion of the terminal assembly tool 3.
  • a part 20 allows to pass behind the wire 4.
  • a part 21 in a plane parallel to the first allows to start the covering the wire 4.
  • the insulated wires to be connected are mounted on the first housing 1 of FIG. 1.
  • the second housing 2 which carries as many lugs as there are wires to be connected, is fixed to the first housing 1 by snap-fastening.
  • the pods are of the form indicated in the figure 2-a.
  • a first bending operation folds the part 22.
  • a hot crimping operation connects the terminals to the insulated wires as described. With appropriate tools, these two operations can be carried out simultaneously.
  • the flat part 21 includes a boss (not shown) which allows the wire 4 to be retained when crimping when the terminal is arched.
  • the boss carried by the front 22 of the part 21 is folded down in front of the wire 4 which it traps between itself and the part 21.
  • the second part 14 of the terminal 3 has the function of connecting the terminal 3 to a track of the printed circuit.
  • a second part 14 is shown according to a first variant.
  • the front part of the terminal has an opening called a lyre 14 between the jaws of which a printed circuit 23, provided with a copper track whose position corresponds to that of the terminal in the connector, is introduced.
  • the mechanical and electrical contacts are established by friction of the lyre opening 14 on either side of the printed circuit 23, to the right of the track.
  • the tracks can be on one side or the other of the printed circuit 23. It is thus possible to alternate the tracks successively one on the upper face, the other on the lower face of the printed circuit board 23. It is also possible to make arrive at the same connection 14 a track on the upper face and a track on the lower face of the plate 23.
  • FIG 4 there is shown another alternative embodiment of the terminal where the second part 14 is of the lamella type.
  • the upper plate 9 of the second housing 2 which carries the terminal.
  • the terminal is twisted so as to be in a plane parallel to those occupied by the plate 9 and the printed circuit 25.
  • the terminal is arched in three successive bends 28 so as to form a resort 27.
  • Au level of the elbow 29 the distance between the spring 27 and the plate 9 is less than the thickness of the printed circuit 25.
  • the track 26 of the printed circuit 25, to be connected to the terminal associated with it in the connector is on the side of spring 27 so that the electrical contact is established. The connection of the printed circuit in the connector is therefore ensured when it is mounted on the connector.
  • the terminal 3 is rigidly held in the housing 2 at the rear of the housing 2 by a shoulder 31 which may include a housing for the part 13 of the terminal 3 on its edge, just like the underside of the plate 9 can , to the right of the previous housing, present the same housing on edge.
  • the terminal 3 can also be blocked at a second point by a spacer 15 fixed to the underside of the plate 9.
  • the terminal 3 comprises a first part 13 for connection to the insulated wire and a second part 14 for connection to the printed circuit
  • another technique for removing the insulation by hooking is used.
  • the terminal is made of a sheet, of brass for example, folded on the side 13 of the wire in two right angles.
  • a slot 33 which terminates on the two faces of the terminal makes it possible to maintain the wire in electrical contact with the terminal.
  • a housing 34 ensures the elasticity of the terminal. The edges of the slot 33 cut the insulation up to the conductive core of the insulated wire.
  • the return of the folding at two right angles makes it possible to form a spring-loaded terminal 27 the second part 14 of the terminal 3.
  • the upper part of the folding which carries means 32 for latching the terminal 3 in its housing of the housing 2 is flat . It is separated from the top of the spring 27 by a thickness slightly less than that of the printed circuit 25. By elasticity, contact is maintained between the track 26 and the top of the spring 27.
  • FIG. 6 a connector is shown according to the invention which uses lugs of the type of that of FIG. 5.
  • the first housing 1 carries eight insulated conductive wires. Connect to the printed circuit board 49.
  • the comb 50 of tracks 51-58 can be single or double sided.
  • the housing 1 comprising three spacers 38-40 the plate 49 carries three notches 59-61 which allow the embedding.
  • the second housing 2 has two parts, 101, 102, perpendicular to the wires, which can be pierced with similar not shown grooves and opposite those of the housing 1. As the housing 2 is introduced according to arrow 62, the grooves of the housing 1 and of the housing 2 are in opposite directions so as to block each wire. In addition, particularly for enameled winding wires of very small diameter, the housing 2 carries, not shown in the drawing, bearing surfaces which come to bear on each wire in the housing 1.
  • a known automatic machine places each terminal 41-48, as in FIG. 5, in the connector according to arrow 63, opposite arrow 62.
  • the wires suitably maintained, are therefore connected to the terminals 41-48.
  • the printed circuit board 49 is introduced into the terminals 41-48 so that each track 51-58 is connected to a terminal 41-48 which is associated with it.
  • the housing 2 carries fixing means, not shown, of each terminal 41-48 by snap-fastening.
  • An assembly of the connector according to the invention is therefore obtained, which can be described as follows. First of all, the insulated wires are installed in their grooves 35 of the housing 1. Then the housing 2 is mounted and snapped onto the studs 36, 37 of the housing 1 so that the wires are blocked. The terminal installation machine feeds each terminal 41-48 onto the wire reserved for it. Finally, the plate 49 is mounted by plugging into the lugs 41-48.
