Definitions

  • the present invention relates to a receptacle for a bundle of electrical conductors connectable to connection terminals and capable of being used, for example for connecting a switch for car window regulators, to one or more manual and / or automatic operating modes. .
  • an electronic delay can be provided, a command by fleeting pressing of a switch key, a selection of several functions, a progressive command by pulses, the detection and taking into account of various parameters. , etc.
  • control assemblies of such devices include in particular a primary electrical circuit constituting a part of a function management electronics, a manual switching device and switching devices for high currents or power circuits (relays) for controlling the load.
  • the control assemblies are generally provided with output connection terminals to be connected to connector boxes which are themselves connected to a vehicle wiring harness.
  • the connector housings occupy a volume which can sometimes be as large and even exceed the volume of the control assemblies. It was therefore essential, for reasons of space, to reduce these volumes and it was quite natural to replace the connector housings with bundles of conductors.
  • each output terminal of the circuit which can be in the form of a connection tab, must be connected to one of said conductors.
  • the conductors are brought together in bundles.
  • the bundle can be obtained by twisting the conductors together so that the stripped free ends or without insulating sheath can be welded to the corresponding connection tabs, each free conductor end being manually welded or crimped to the connection tab.
  • the conductors are of unequal lengths due to the positions occupied by the connection tabs, it is necessary to pull one of the conductors of the harness, starting with one of the sides of the circuit.
  • the FR patent. 2,204,863 relates to a switch comprising in particular a three-conductor cable which is cut to allow certain sections of the conductors to be separated from each other, the sections thus separated being able to be housed in notches provided for this purpose in the housing.
  • An object of the present invention is to provide a bundle of conductors in which it is not necessary to separate said conductors from one another, and which allows each of the conductors to be connected securely and without manipulation to the corresponding connection tab .
  • An advantage of such a characteristic resides in the fact that there is in the presence, at the level of the circuit, a layer of conductors, the width of which is substantially that of the circuit and the thickness of which is at most equal to the thickness to the diameter of the insulating and protective sheath of the conductive wire.
  • the bundle of conductors is flat and arranged on one face of the circuit through which two lateral ramps of connection tabs open, said flat bundle being disposed between said lateral rows.
  • Another advantage of the present invention is that when the receptacle is fixed to the circuit, any movement of the conductors is prevented while allowing prepositioning according to the position of the output terminals, so as to automatically bring the folded ends of the conductors opposite or above the output terminals, which greatly facilitates connection.
  • the invention is as defined in the characterizing part of claim 1.
  • Figure 1 is an exploded view of a receptacle associated with a circuit of a switch.
  • Figure 2 is an exploded view of the receptacle according to an embodiment of the invention.
  • Figure 3 is a plan view of an example of a pre-cut primary circuit used with the receptacle according to the present invention.
  • FIG. 4 is a perspective view of the overmolded circuit of FIG. 3.
  • Figure 5 is a top view of a switch with the control button removed.
  • Figure 6 is a view along VI-VI of Figure 5 but with the control key.
  • the bundle of conductors 1 comprises at least one layer of conductors.
  • the conductors are substantially adjacent to each other and are located substantially in the same horizontal plane.
  • the bundle 1 comprises six conductors 2 to 7, of unequal lengths, the conductor 2 being smaller and associated with an output tab 8a of a circuit of the type shown in FIG. 3, the conductor 4 being the longest and associated with the output tab 8b.
  • the free ends 2a to 7a of the conductors 2 to 7 are folded at a right angle so as to come opposite or above the corresponding output tabs, depending on the connection mode chosen to connect said conductors to said output tabs.
  • the end parts 2a to 7a can be stripped before their connection to the outlet tongues 8.
  • the connection can also be made by displacement of insulation when the edges 9 of the forks 10 of the outlet tongues are sharp.
  • the parts of one end of the conductors are overmolded in a receptacle 11 which is shaped such that it can be inserted between the lateral rows of outlet tongues 8, with the folded ends 2a to 7a of the conductors 2 to 7 free, not overmolded and opening laterally so that they can be connected with the corresponding output tabs.
  • the connection of the receptacle on the face of the circuit preferably overmolded, can be produced by means of connecting studs 12 engaging in orifices 13 formed for this purpose in the receptacle 11.
  • the receptacle 11 it is made in two parts 14 and 15 which may or may not be integral with each other, the separation being shown in FIG. 1 by a dotted line 16.
  • the lower part 15 is provided with grooves 17 in each of which is housed a conductor, the upper part 14 then constituting a kind of cover which can be connected, for example by a flexible hinge to the lower part 15 so as to constitute an openable housing.
  • the receptacle 11 can also be constituted solely by the upper part 14 forming a cover on the internal face of which grooves 17 are provided for housing the conductors 2 to 7.
  • grooves 17 In all cases where grooves 17 exist, these each have a length equal to that of the corresponding conductor.
  • the receptacle according to the present invention has a small volume and can be inserted between the rows of the output tabs of the circuit.
  • the receptacle includes areas cut both to lighten it and possibly to constitute a gripping area.
  • the grooves 17 are formed so that the conductors open on the lateral faces and not on the upper and / or lower face of said receptacle. However, if this were necessary, one could provide outlet openings on the lower and upper parts 14 and 15 for the conductors 2 to 7, depending on the positioning of the outlet tabs 8 of the circuit.
  • each conductor When the connection of the conductors 2 to 7 with the output tabs 8 is carried out by displacement of insulation, there is provided for each conductor at least one opening formed in the upper 14 and lower 15 parts, of which only one 7b corresponding to the conductor 7 shown in figure 2.
  • the circuit 23 which is associated with the receptacle 11 with its bundle 1 of conductors is precut and comprises (FIG. 3) tracks 18 which are connected to each other in the usual way.
  • Two extreme lateral foldable tracks 19 and 20 are also precut and are intended to receive electrical contacts 21, other electrical contacts 22, being provided on some of the tracks 18.
  • the electrical contacts 21 and 22 are produced on a strip. comprising a number of circuits 23, similar to that shown in Figure 3, and attached to each other. In this way, the positioning and the making of the electrical contacts can be done relatively quickly, with good precision and automatically, with suitable means which are not described since they are not concerned with the present invention.
  • the circuit 23 also includes connection tabs 8 which are provided at suitable locations, so that after folding, the circuit 23 takes the configuration shown in FIG. 3 in which the output tabs 8 are substantially orthogonal to the horizontal plane containing the tracks 18. It is understood that depending on the configuration of the circuit and its use, the output tabs 8 can be folded up instead of being folded down, some of them being able to be horizontal.
  • free ends of the outlet tongues 8 are in the form of a fork 10 which appears to be the suitable form for receiving conductors and even partially stripping the conductors, as is known under the name of displacement of insulation by specialists in the field.
  • edges 9 which is sharp so as to effect a partial removal of the insulating sheath surrounding the conductive wire during the forceing of the complete conductor (wire and sheath) in a fork 10.
  • the two edges 9 of the fork are sharp.
  • the lateral tracks 19 and 20 each have preformed notches 24 and 25 to facilitate folding.
  • the lateral tracks 19 and 20 can, independently of one or both of them together, be folded back so as to occupy various positions represented in solid lines and in dotted lines in FIG. 4. They can be held perpendicular to the upper face 26 of the circuit, or folded back so that they are parallel to said upper face of the circuit, the contacts 21 being, in this case, opposite the contacts 22, or even occupying an intermediate position, that is to say -to say inclined on said upper face of the circuit.
  • the position of tracks 19 and 20 will essentially depend on the positioning of the rocker or other mechanism associated with said electrical contacts.
  • the circuit 23 comprises support means 27 for a mechanism such as a rocker and support means 28 for a component such as a light emitting diode for example.
  • the rocker support 27 consists of two portions of circuit 29 which are folded along notches 30 so as to be parallel to each other and substantially perpendicular to the upper face 26 of the circuit 1 ( Figures 3 and 4).
  • the rocker is of the type comprising a frame "1 and a spring 32, as shown in FIGS. 5 and 6, then the circuit portions 29 are provided with latching notches 33 and larger notches 34 of positioning of the rocker (figure 4).
  • the circuit 23 includes two support members or means 27 because it is intended to be placed in a switch with two rockers, as will be described with reference to FIGS. 5 and 6.
  • the support member 28 is also folded back to occupy the position shown in FIG. 4, that is to say perpendicular to the upper face 26 of the circuit.
  • the tracks 19 and 20 occupy vertical positions which are not the final positions.
  • the underside 35 is overmolded, that is to say covered with an insulating layer 36, which is provided with fixing lugs 37 for the switch, come with said insulating layer during overmolding, so as to obtain an overmolded circuit as shown in FIG. 4, passages for the passage of the outlet tongues 8 having been provided during overmolding.
  • a simple way of carrying out overmolding is to deposit the circuit in a mold, the foldable parts being arranged vertically; the overmolding of the lower face of the circuit is carried out so that the upper face of said circuit is substantially level with the upper surface 38 of the overmolding, as can be seen in FIG. 4.
  • the output tabs 8 are in a certain position determined by their cutout on the circuit 23.
  • To each output tab must correspond a conductor of the bundle of conductors 1.
  • conductor is meant the 'assembly consisting of an insulating sheath in which is disposed a conductive metal wire.
  • the circuits 23 with the beams 1 can be used in numerous pieces of equipment, such as for example a switch for automobile window regulators as shown in FIGS. 5 and 6.
  • a switch for automobile window regulators as shown in FIGS. 5 and 6.
  • the mechanisms supported by the circuit are constituted by two rockers.
  • Each rocker 43 is constituted by a frame 31 which is supported by the support members 27, the frame 31 being arranged, by one of its sides, in the notches 33 of the vertical walls 29 of the support.
  • the rocker comprises a leaf spring 32, one end of which bears on the bottom of notches 33a formed in vertical walls of the support 27, and a contact 44 carried by a central blade 45 of the rocker.
  • the lateral tracks 19 and 20 of the circuit 23 are parallel to the upper face 26 of the said circuit, so that the contact opposite the contact 44 of the rocker cooperates with the upper contact 21 of the circuit.
  • the switch usually comprises a control key 46, a housing 47, a piston 48 with its support 49 acting on the central blade 45 of the rocker, a partition wall 50 and a light-emitting diode 51 mounted on the support column 28 which is an integral part of the circuit.
